A custom harness backed by dagger, gives diff, time travel, forking of both files and env. Building a harness is a good learning project. I'm now using other tools to see what they are like. (OpenCode is quite good out of the box)

Currently working on a markdown search and wiki backed by Typesense, also has good web search, fetch, crawl. This will power my personal knowledge base system as an important step towards more leverage and better outcomes.

Ive made some tools after "the advent of AI"

But I dont use "AI" to make them

I use a code generator

I like to use the smallest possible "toolchain", using the least possible resources, to build software tools

Ideally I want the tools to compile quickly on underpowered hardware

g8oz• 1 month ago

What code generator?

What code generator?

Simulacra• 1 month ago

I've vibe coded multiple helpful apps and websites for recording data. But longer term, I'm building with its help an internal research system to organize, search, compare, analyze, and esp reuse all the large amounts of data my firm produces, with the public materials without constantly starting over in separate ChatGPT or Claude conversations.

teaearlgraycold• 1 month ago

Similar to you, the things I have truly vibe-coded (having looked at <5% of the code) are largely data focused. Data labeling, organization, etc. These applications are extremely janky, I'd never ship them to users. The UI is mediocre at best. The functionality hardly better. But the point is to get data out of them. The code is a means to an end and not a product in itself. Building a custom dataset builder in just a couple hours of work is really powerful.

Claudhd

It's a user daemon that runs on my machine and exposes a unix socket, and then a bunch of hooks in claude, zsh, vim, etc, that report directory and commands I've run and all that, pipes it to claude Haiku for summary, and then stores context in sqlite. It also exposes that data as MCP so I can use claude to say "hey what was I doing yesterday," or any arbitrary time range.

I find that in the age of using AI agents, "Wtf was I working on yesterday" is an even harder thing to remember for me, so this helps me kind of track everything with a database that a) has AI summaries already and b) can be accessed by AI as well as a CLI.

gitaarik• 1 month ago

What does it matter if it was yesterday or last week, and why would git log not suffice?

andrewstuart22• 1 month ago

Because I work across a dozen repos any given week, and I have my own side projects I play with as well. It blurs together. Global git hooks are another data source for the project, which I'd forgotten to add, so that data is in there too.

zigapotocnik• 1 month ago

The "expose it as MCP so AI can query it" pattern is one I keep seeing work really well in practice. We did something similar for business metrics in Databox - the interesting design question was whether to expose raw data or pre-aggregated metrics. We ended up with metrics (with dimension breakdowns) because agents hallucinate less when they don't have to decide how to aggregate themselves. Curious if you ran into anything similar with the sqlite summaries - do you find the AI-generated summaries more useful than raw command history?

xcubic7• 1 month ago

How do you do this? (The hooks part)

c0nsumer2• 1 month ago

Three that have been really beneficial, and all support/build on a hobby / volunteer effort of mapping mountain bike trails:

This one generates maps from OpenStreetMap data + some custom curated info in YAML: https://github.com/c0nsumer/trailmaps.app-map-generator

This one converts a basic chunk of OpenStreetMap data to an SVG so I can mark it up (by hand) in Adobe Illustrator to make specifically-styled print/PDF maps, such as what get installed at trailheads: https://github.com/c0nsumer/osm_to_ai

This one takes GPS recorded rides and builds custom/personal heatmaps serving up the map tiles so I can use them in map editing software: https://github.com/c0nsumer/local-heatmap-tile-server

And all of this has been put together to make the custom, local, specific-use-case maps that are at https://trailmaps.app (which, via local curation, are overall better mobile/online maps than many of the bigger auto-generated systems such as Trailforks, Gaia, RideWithGPS, etc, for visualizing local systems).

It's neat stuff where I understand all the inputs, outputs, and how most of it works, but AI tooling (Claude, mostly) has allowed me to bolt it together much faster than I would have writing it myself.

thenthenthen4• 1 month ago

Ooh the heatmap to tiles idea is cool!

c0nsumer2• 1 month ago

Thanks!

The idea came from using the Strava heatmap in JOSM to trace the proper location of mountain bike trails. I'm trying to use Strava less, and usually have ridden the trails enough myself before mapping them that I could use my own routes... So I figured why not have my own heatmap tile server?

It's also cool to just look at.

I could take it a lot further with time boxing what's displayed and whatnot, but generating the tiles is computationally expensive, so I just stuck with what I have for now. It meets the need.

My agent checks my session logs to look for things that I should automate. I blogged about how I got there: https://austinhenley.com/blog/automatingmyjob.html Maybe I'll share some of the skills.

jboggan• 1 month ago

I built a half-baked CRM that has a lot of custom fields and visuals for statistics that are relevant to my potential customers. I'm selling primarily to registered data brokers, so being able to pull up their self-published compliance stats (gleaned from their own privacy pages or public filings) and contextualize them in terms of the rest of the industry ("your deletion request volume has been in the 95th percentile year over year") has been extremely helpful when starting conversations. I also gamified it a bit by giving myself targets for cold outreach and gathering hard numbers on my cadence for outbound calls and emails per lead.

I also built this site for educating potential customers and other privacy professionals about the increasing tempo of CCPA enforcement actions driving compliance: https://ccpa.world/enforcement

I could have probably coded this from scratch quicker considering that it took me two weeks to remove all of the hallucinated imaginary enforcement actions against real companies and also the citations to non-existent California law that the models kept injecting into my enforcement summaries.

bnchrch• 1 month ago

Oh man a few things

1. A dashboard that tracks my personal metrics (github, strava, todo completion, flossing)

2. A eink display for that dashboard

3. A realtime node graph that shows a codebase (and/or its diffs) in a way that I can visualize what functions call which, and under what conditions

4. A agent that automatically fills out government forms and creates invoices for my friends brewery based on the delivery notes in their google calendar.

naorsabag• 1 month ago

That sounds useful. I went a smaller/specific route with OpenHop: not a full graph of everything, just agent-authored flow walkthroughs you can step through locally.

kstenerud• 1 month ago

I made a tool that creates sandboxes (docker, podman, orbstack, seatbelt, tart, containerd, kata, firecracker) and then sets up an agent (claude, codex, gemini, aider, opencode) inside it with max permissiveness (no prompts to call sed, etc).

It creates its own copy of your workdir for the agent to play in, and then you pull changes out ala git diffs or commits.

It's a MASSIVE time saver, and I use it as my daily driver.

We used AI to build our AI platform and now we are using the AI platform to build the tools that we need for AI. :)

But no honestly, unfortunately most tools I did for myself are not for hobbies but something that I needed for work... like this one (https://github.com/crmkit/crmkit) most recently.

seidleroni• 1 month ago

The tool I'm most proud of is "Hex Flex" (https://seidleroni.github.io/Hex-Flex-Web/). It is a tool to view and compare the contents of Intel Hex files. Should be useful to other people who work in the firmware field.

Not exactly a tool, but I also made pelohard.com which ranks the most recent Peloton classes by difficulty. Updated twice daily.

imping - PingPlotter-like app. They didn't have a Linux version and I'm a paying customer, so I vibe coded this one: https://github.com/zenakuten/ImPing

utcolor - text colorizer for Unreal Tournament 2004 https://github.com/zenakuten/utcolor

utquery - Unreal Tournament 2004 Game Browser tool https://github.com/zenakuten/utquery

utstatsdb - This is an old project that did not work anymore with modern php+mysql. I had claude fix it. https://github.com/zenakuten/utstatsdb

BlueHotDog2• 1 month ago

created https://github.com/frontman-ai/frontman, not exclusivly for myself but something i'm passionate about(might turn into a paid product).

basically trying to see what a vertically integrated agent looks like, where the agent has deep access inside a framework and it operates from within a framework, so like, instead of reading files, opening processes etc - it gets a bunch of framework specific runtime tools(logs are the easiest example)

agentifysh• 1 month ago

Most of it has been to maximize productivity with AI

1) Use chatgpt pro from codex cli, opencode, claude etc as you can't get it via API. This has been the biggest boost in productivity for me as I don't have to copy and paste.

https://github.com/agentify-sh/desktop

2) A small gate to make sure any agent cannot run destructive rm -rf or git reset --hard commands, it has saved me many many times

https://github.com/agentify-sh/safeexec

3) For mac users, summarizes and speaks out loud after codex finishes a turn

onlyrealcuzzo• 1 month ago

I'm close to releasing a memory safe programming language, with a declarative concurrency model, that runs on a Go-like runtime.

It has "levels" of compilation, with EASY mode being about as easy as Ruby, and the compiler can present you with options to get that as strict & performant as Rust/Tokio.

I'm going to need at least a month to finish all the documentation, though.

https://gitlab.com/grepular/calendiff - Point it at a .ics URL and it monitors for calendar changes and emails you about them.

https://gitlab.com/grepular/foxcage - Runs Firefox inside podman to isolate it from the host. Has some interesting features that I wanted and nothing else gave me.

https://gitlab.com/grepular/claude-sandbox - Yet another Claude sandbox. Runs it inside podman again. Has a pretty powerful proxy system for securing your credentials.

Currently working on a tool for sanitising email. Will be blogging it up at https://www.grepular.com/blog/ when it's ready for others to use. Does things like applying policies to html/svg/calendar/vcard parts to whitelist or blacklist tags/attributes/css/url schemas, clean URLs, fetch remote content at delivery time and attaching to the email to prevent tracking, pgp and smime auto encryption/decryption and a million other features.

mixedbit• 1 month ago

I made a sandbox to productively work with agents while restricting files they can read and write: https://github.com/wrr/drop

epiccoleman• 1 month ago

All kinds of random stuff really, but to filter it down to only the noteworthy ones:

Tuber[0] - this is my favorite, use it multiple times a week. It's just a little CLI wrapper around yt-dlp for my most common use cases - downloading the video, or the audio, or the subs. And then, if you've got the Claude CLI installed, it can also shoot the subs through Claude for a summary. I use it all the time, it's a great little thing!

Scrapio[1] - this is really specific but I was so pleased with how it turned out. You give it a list of "hacks" ("mods" for Super Mario World) and it goes out to SMWCentral, grabs each of the patch files, and patches a clean ROM. I think I only used it twice but it was just a nice way to chew through a list of hacks and get a few ROMs ready, made quick work of something that would have otherwise taken a bunch of annoying schlep work.

Lotus Eater[2] - calling this a tool is a bit undersell, but I'm still really pleased with it. It's a fan site for jamtronica greats Lotus that scrapes Nugs.net for setlist data and lets you do some mildly interesting analysis on things like song frequency and co-occurrence. Also has a per-user "shows I've attended" thing, Setlist Bingo. It's been fun to hack on.

Lastly, less a tool, more just a toy: last week Google released their Magenta model for doing live music generation. I thought it was really neat, and it's open source, so I opened it up with Claude, and after a few passes and some extremely annoying toolchain issues, I was able to add a spectrograph which does key / chord analysis to the "Collider" app, so you get a live readout of "what the band is playing" and you can pull out your guitar or whatever and join the jam with some info at your disposal. It's the kind of thing that would have taken way too much effort to be worthwhile in the past, but with AI, it's a really neat result of a fun night of weekend hacking. See the README I added in my fork for a screenshot:[3]

I'm building an app that uses cosign similarity across a bunch of vectors to derive team productivity metrics. To be honest the maths is trivial; the hardest part is gathering data and normalizing it in a vaguely sensible way.

I've also built a release notes app for my QA teams, a DORA metrics app, a thing to map UX journeys with Playwright, and a ton of games and stuff. AI got me back into enjoying building things again.

Lookup or modify selected text using AI (chrome extension). I just select any text and click the tiny popup button "what's this" and get an answer right there on the page. Made it mainly to explain terms and abbreviations I come across on HN often. Can also ask any other question about selected text. Can even modify the selected text the same way. [1]

OneNote to markdown/obsidian canvas converter. It did that using interop api to read the actual XML of the onenote files.

Work time tracker as 1px line on edge of monitor. Shows thin line at the edge of the display which fills up based on what i am doing.

Plaintext bookmark chrome extension that save links to local markdown file, Dynalist, Workflowy, Github Gist and import export between them. Was originally for Dynalist when AI couldn't do much 2-3 years ago. Recently added these other end points. [2]

A heart rate monitor with finger on camera. It's bit crappy though. Had to make it because many trackers, including google fit, couldn't detect 200bpm. https://github.com/SMUsamaShah/heart-rate

raffraffraff2• 1 month ago

I'm working on a recommendation service (which, to me, it's the piece I'm missing when I play my local mp3 collection)

I collect song metadata from various places (genre, instruments, track credits, rating). I also scrape charts by year, genre etc.

Then I run an ETL job on the json data I have downloaded, pre-building queries for extremely fast lookup tables. This gets saved to Duckdb, which is used by my go web ui/api.

It's very early days, and I only spend one or two hours a week on it, but right now it's amazingly useful. It had roughly 80k song metadata. To preview the suggested songs I ended up building a very cut-down YouTube music player, except that the playing song has all the metadata right there, and everything is a link that can take you to the artist, composer, instrument, genre, album etc. It's a great way to "wander through your collection".

Unfortunately this is only useful to me, because I targeted the music I listen to.

Next step is to download lyrics and extract song meaning, keywords etc. Then use MusiCNN, (or CLAP,OpenL3, HTSAT) to extract embeddings. Finally train my own model for nearest-neighbor retrieval based on a mix of metadata, giving the user the ability to tune it on the fly.

bijowo16762• 1 month ago

Did you ever have to pass Appstore review process? How do they look at copyright and stuff when you are publishing an app that plays your local mp3 collection (how does your mp3 collections ends up on your phone?)

nickjantz• 1 month ago

I tried to do something like that here: https://musicdocks.com/

Github: https://github.com/jantznick/youtube-spotify

It essentially uses youtube as the music source, I think I heard somewhere that playing through embedded videos skips ads but I'm not really sure, in all my time testing it I never noticed ads, but I'm also on premium so that may have been why.

by all means critique, I don't know that I have a ton of time left for it and I'm sure there's bugs here and there. I was having issues getting it to autoplay on desktop when the window itself wasn't the active tab. I never really tried it on mobile.

I was trying to get some DB of artist/song info but doing that was proving to be complicated.

FailMore• 1 month ago

I built https://sdocs.dev and use it daily. It’s a CLI-driven markdown reader which (privately) renders Markdown in the browser.

When you install the CLI, it (with your permission) asks to update your base agent prompt files (e.g. `~/.codex/AGENTS.md`, or `~/.Claude/CLAUDE.md`) with info about how to use the tool.

This means all your agent chats know about SDocs, and it’s nearly always your agent which invokes the tool: “Hey Claude, sdoc me a list of all my open MRs”, etc.

I did a ShowHN about it here: https://news.ycombinator.com/item?id=47777633

https://charleswiltgen.github.io/Axiom/ – Suite of skills, agents, and tools that make general SOTA models actually good at building and/or auditing iOS/macOS apps. Built for myself initially, I FOSS'd it once I determined how generally helpful it was. It's helped me learn a lot about doing sophisicated things with LLMs in a token-efficient way.

https://charleswiltgen.github.io/TagLib-Wasm/ – Also built for myself initially, I FOSS'd it because there was nothing like Mutagen for TypeScript/JavaScript runtimes. (I don't dislike Python, but think it's a bit of a mess.) This was my first serious project to leverage LLMs for coding.

https://pwascore.com/ – Built because I wanted to quantify how bad Safari was at PWAs. Learned that, objectively, Safari is as bad as PWAs as Firefox (which is to say, not terrible, and not to blame for why PWAs continue to be mostly-irrelevant).

Some things I’ve used AI for the last year or so:

- small club website: https://www.kolibrinkpg.com

- ticketing system with Stripe payments and QR scanning at the door

- Instagram/media ingestion for the club site

- genealogy tool with GEDCOM import

- scripts for downloading/archiving public-domain film material

- playlist/library tooling for DJ use

- music collaboration/sync tool for Ableton projects

- normal work stuff in a much larger existing codebase

I have become a lot more strict about process after being burned a few times. Mostly: make the change small, be clear about what it is supposed to do, check the assumptions before coding, use tests/logging/manual checks as evidence, and don’t merge anything I can’t review and explain myself.

The main worker is a .Net API with Hangfire that hits a public facing API from the radio station. That data is stored in a MySQL database that feeds a React dashboard front end.

There's some caching that happens behind the scenes to help with some of the large data crunching.

asciimoo• 1 month ago

I'm working on a self-hosted search service called Hister (https://hister.org/ - https://github.com/asciimoo/hister) with the goal to reduce dependence on online search engines and AI answers.

Hister is a full text indexer for websites and local files which automatically saves all the visited pages rendered by your browser. It provides a flexible web (and terminal) search interface with offline result previews & detailed query language to explore collected content or quickly fall back to traditional search engines.

It can provide a privacy-respecting search experience for serving "recall" type searches where users retrieve previously visited content, but falls short in "discovery" type searches (yet).

SyneRyder• 1 month ago

This was the first AI project I ended up working on as well, except I approached from building a meta-search first. I only added support for a local index recently (via SQLite FTS 5). But I haven't shared my project, whereas you have a truly fantastic webpage for yours. Plus going the extra distance with a terminal interface and MCP server too.

Much kudos. I hope more people discover how powerful even a local search index of previously visited content can be. And I hope more people can build large indexes as well, so we're not just relying on Brave & Mojeek & Marginalia (and EUSP) to rescue us for the fallback discovery searches.

A voice memo app, quite like the actual voice memo app from Apple. The thing is: now I can put my voice memo's on iCloud put Claude Code on it and make my transcripts into structured notes that my app then also displays.

So basically a way to just go on an hour long walk with myself, spit everything from the top of my dome stream of consciousness style, and then have Claude structure whatever I said.

It's nice to have something that structures my thoughts by just thinking out loud.

I vibecoded it (it's approaching 20K lines including tests). It works quite well but there are some bugs, so will have to do some actual engineering. But the UX is working quite well.

hsuduebc2• 1 month ago

It seems clunky for me. The dictating it self had weird bugs, like sometimes it decided to not work at all and the conversation mode is not very usefull for OP case if I am undestanding it correctly.

jascination• 1 month ago

FWIW - In the Claude app (on android) when in transcript mode, it has a hard limit of 10 minutes. If you transcribe longer than that, it crashes and you lose everything you've said.

To make matters worse, they've recently gotten rid of the timer, so you have NFI how long you've been speaking for.

I use it for therapy-based stream-of-consciousnesses + venting and then have my project set up to understand the schema therapy work I've done with my psychologist and give me insights / draw threads between things from my past and now, and losing 10 whole minutes of talking and processing is SO FRUSTRATING!

I am curious to check them out! I hadn’t heard of them. Marketing stuff takes time as I have noticed with aliceindataland.com [1]. Maybe I should do a show HN. I will think about it.

To be fair, vibecoding this memo app in Swift didn’t take too long. There were some tricks to it, using xcodegen helped a lot so that I don’t need to use the Xcode project.

It’s fun to see Swift code. I used to do some Objective-C back in the day.

[1] another thing I made. It’s a sequel to the Alice in Wonderland stories. It’s also a SQL course. I vibe engineered it, meaning I looked at the code and used AI-assisted development.

Except for the story though that’s almost all fully me. LLMs aren’t great storytellers. The same is true for the lesson scaffolding, that’s almost only me.

prometheus76• 1 month ago

Relatedly, I have recently started walking and talking, and I just use lightweight gamer headphones that have a mic. I just record it with a generic voice recorder app, then I use a local instantiation of whisper to transcribe it when I get home. I throw the transcript and the recording into a database and then I can search the whole thing, or have AI look for interesting patterns in my thoughts.

* Auto-Birthday - if you have a contact in your android contacts that has both a mobile number and a birthday in their contact info, you can choose to send them an automatic "Happy Birthday" message on their birthday at a specific time. Can do it with hundreds of contacts. Doesn't use hardly any battery or resources.

* Wrecker - stupid simple "throw a ball at a tower of bricks and try to clear the board" game. High score tables. Made in unity. High battery when in use, No battery use when not playing. Will use internet for high score data.

* GeoNote - Create Geo-fences to generate a notification when you enter a location with your custom text in the notification. My wife is always telling me, "Next time we're here, remind me to only order one piece of toast" or something like that, so I make a note, it pops up the next time we're there and we're both happy. Notes are stored locally. No internet access required. Uses Geo-Fencing which is more battery-friendly than always-on GPS access.

All my apps are free, very privacy-focused and as battery-friendly as possible.

No information leaves your device (other than the high score data in Wrecker).

You have to side-load my apps though. I'm not putting them on the Google Play Store. They're so annoying to deal with! OMG

Haha yes.

It probably should message YOU rather than the person who's birthday it is, so you can send something personal.

At work, I've created a few convenience scripts in bash and Python - the second of which I am not fluent with. So, I used anonymized LLM access to create boilerplate/simple scripts with a bit of argparse and NumPy, which I then adapted to do what I actually wanted.

Would have made them without UI with a bit more elbow grease invested in web-searching for some examples, maybe even a StackOverflow question.

Generally, I'm not a fan of LLMs and their social effects.

Too many to enumerate but a couple highlights (and many of these I've turned into apps):

- https://blunders.ai : Chess improvement app

- https://fretwork.ai : Freelancer management app (CRM/Billing/etc)

- https://validity.ai : Provide agents the ability to check the UI code it made (w/out needing to run through your full app)

- Save money on groceries + meal planning. This has probably saved hundreds if not $1k+ for our household at this point (some details here: https://x.com/ryanlanciaux/status/2063604299590939042)

llm-consortium: prompts multiple models in parallel, loops until confidence_threshold, and iteratively refines a response.

This was inspired by a karpathy tweet [0] and the prototype created using another tool of mine: The LLM Plugin Generator plugin (essentially a curated collection of plugins for simonws llm cli as a few-shot prompt)

The llm-model-gateway companion plugin lets you serve models from the LLM cli as a an openai API. This allows you to use saved consortiums in your various clients as if they where a regular model. Bringing massive parallel reasoning to any workflow.

It occured to me at some time that an collection of parallel LLMs was not really a consortium. A consortium is a group of organizations. A group of groups. To rectify this I added for actual consortiums, where each member of an llm-consortium can itself be a consortium of models. e.g.

llm consortium save cns-glm-n3 -m glm-5.1 -n 3 --arbiter mercury-2

llm consortium save cns-k2-n3 -m kimi-k2.6:3 --arbiter mercury-2

llm consortium save cns-meta-glm-k2 -m cns-k2-n3 -m cns-glm-n3 --arbiter cns-k2-n3

Yes, even the arbiter/judge can be comprised of a consortium of models, bringing parallel reasoning to the task of judging parallel reasoning chains.

Consortiums can also now contain groups of specialists. These custom user-defined expert characters address the prompt from a different perspective. And a Westworld style Attribute matrix can be randomized to inject some more entropy into the process.

[0]https://xcancel.com/karpathy/status/1870692546969735361

Some other llm plugins I vibe coded:

classifai generates labels with approximate confidence derived from logprobs

llm-alias-options saves inference parameters such as reasoning effort with a model alias. (good for setting the provider in openrouter or creating a consortium of high temperature models)

llm-prompt-json adds a --json flag to return the llm logs object (good for getting conversion_id, or reasoning output in scripts)

llm-jina adds support for all jina AI specialised models and tools like web fetching, embedding and reranking.

i built a program that watches wifi traffic and if it sees my phone connected to the office wifi; it marks me as in the office on our internal chat tool (Zulip).

And the inverse as well, of course.

Runs on a raspberry pi that I was otherwise using to take backups periodically… has been working pretty good honestly.

I also built a program that fills/submits my time reports, and does the same for all of my subordinates - then signs them off… Saves everyone like 5 minutes if we remember to do it, or 12 minutes and frustration if we’re reminded by HR about it (which happens because who the hell cares about time reports?)

It's not just for myself, but I'm primarily creating it for myself - it's a browser for designers. I work in code but I often want a figma-type interface to explore different ideas without having to branch or litter my codebase with a bunch of demo components/files.

Normal browsers have built-in dev tools - this has built-in design tools. so I can visit my app, open up a surrounding canvas, pull fragments into the canvas, do some design-ish stuff, and merge it back into code. All in the same UI. It was cool enough that I'm going to release it, but for now it's very useful for myself.

Many, really, but there are few I'm especially proud of:

- https://github.com/exlee/pikchr_pl - DiagramIDE (diagram amiga-style workbench where you can script Pikchr diagrams using TCL, Prolog, Pikchr or - recently mruby). Note: you need to navigate to actual crate for description. There are binaries built in case someone wants to try it.

- https://svg.axk.sh - semi manual SVG fitter so that I can easier vectorize AI-generated pseudovector images (who doesn't like 30kb SVG versus 1.8mb PNG?!)

- https://github.com/exlee/rik - this one makes me laugh every time I use it - it's an AI harness with text editor as an UI (i.e. it reacts to comment strings) - I gave it personality so it makes wacky comments but other than that it's very constrained agent (limited edition ;))

These are not vibe coded but AI made it much easier to slide through major friction points (e.g. for SVG fitter I really didn't want to reinvent fitting algorithms)

rpdillon2• 1 month ago

These are really cool - I've been meaning to return to my pikchr-in-wasm IDE experiment. I only ever built a PoC, and that was before AI coding. I should pick it back up and polish it a bit, but after seeing your DiagramIDE, I might just use that.

I have made a TUI tool for organizing and authoring sermons written by myself. It also has a third mode for reading one or two bible versions in parallel. I love the interface and keep adding features to make it easy to navigate in and something that actually helps me to organize and write sermons. Some features are to have notes at specific places in the bible, summaries, notes, exports to html/pdf, metadata for each sermon and autofocus on widgets when changing between the three modes. Happy to work in the terminal this way. :-)

Dictation tool which works better than the built-in Apple functionality, for my use cases.

Bc my version uses simple copy/paste rather than deeper OS integration, it works more reliably in the Claude Code terminal (has to do with active windows or cursors or something). And bc it uses local Whisper, I also find it transcribes technical words such as “git” more accurately.

Nothing technically challenging but practical for me.

Originally I felt there should be an alternative to Google and Facebook. It felt like our lives were being ruled by tech giants even ten years ago..and then all the advertising and algorithms really messed with us. I personally wanted an alternative way to use the web. So it's based around what I'd use on a daily basis. And then the idea of being able to extend it with a native app builder.

how is autocomplete implemented ?

keithnz2• 1 month ago

autocomplete isn't "exact", so it does have in its suggestions things that don't exactly always make sense, but it does list things by what is contextually relevant. It has a basic understanding of sql syntax such it will suggest potential keywords next, it introspects things like tablenames so they are available in spots where a tablename would be relevant, and if it has tables it will introspect them to get fieldname, and any named things like x as y will also become suggestions within the context of the query you are working on. This results in mostly correct suggestions. However it generally always has the suggestion you want, it works really well with field names / table names, which mainly what I wanted, and very basic with sql syntax (which I normally don't need any help with other than relevant keyword completion)

Built a tool to help design cs/science inspired jewelry in CAD. I wrote a DSL to describe the jewelry, and had an LLM write the interpreter to generate a CAD file using cadquery (note to self: LLM suck at 3d reasoning). I would not have had the time to do this without AI.

Also used AI to design an online store (I'm not a front end dev). It's amazing to see my wife (non-technical background) tweak the web-site using claude code.

End result: an online store where we sell jewelry pieces that actually are lambda-diagrams (Tromp diagrams) that compute Graham's number, or of the Y-combinator (well, technically it's just a fixed point operator, one beta reduction away from the Y-combinator. But Y-combinator was not aesthetically pleasing from a jewelry point of view)

note to self: LLM suck at 3d reasoning

one trick on 3d reasoning: get it to draw all the different orientations, and you pick which one to use

it save a lot of time vs trying to tell it to rotate around Y and it actually rotates around X

Thanks. Good idea.

What I often ended up doing is asking it to draw 3 labeled arrows X,Y,Z. So I could tell it to orient along the XY labeled arrows (which are in reality YZ, but whatever).

I've found that Gemini Pro is surprisingly good at 3d reasoning. To back that claim up, I've had it create:

A WebGl program that takes input like X123 Y123 Z123 via WebSerial every 100 ms and builds an object out of the resulting path. Required some performance optimizations (just had to tell it what to do). Also asked it to make the corners nicer and it did. (To be fair, I'd already asked a lesser model and put some things in the prompt to nudge it the right way.)

Various OpenSCAD models. E.g., remote control holder with 5 slots, staggered heights, slight slant because it looks cool, and the slots all have different depths. One shot. It implemented the slant/tilt using a shearing matrix. 100 points.

I schedule reminder calls to myself before some important appointments. It keeps calling me until I receive the message which it reads me (I set the message when scheduling the reminder call) and I have to say "message received" which marks the notification as delivered. (I use Twilio to place the call.)

I find a phone call is more likely to get through to me than a reminder or alarm, which I can ignore or forget; an ordinary reminder is not as interactive.

Claude built it all and although there's a script for it, I just set the reminders in an interactive Claude code session in the directory. (Like I'll open a claude code session there and say "using the script in this directory, call me tomorrow at 7 a.m. with the message 'dr's appointment'."

It works well for me.

I vibe coded myself a simple little Home Screen-installable webapp that tells me when my first meeting is the next day (I am in a lot of meetings, and they're constantly in flux). That way, I don't need to be logged into anything work-related on my phone, or even mentally engage in that world. I just want to know when I need to wake up. All it shows me is the time, and I can tap on it if I want to see the title. It adjusts the font and color according to how early the meeting is (earlier than 8a gets Nosifer).

Could I have done this myself? Of course. Would I have tho? Prob not.

This kind of simple, hyper-specific bespoke utility is the perfect thing for vibe coding IMO.

Do you have a write-up on how it works under the hood or is it meant to be more mysterious?

feerfreeflight3• 1 month ago

Sure! I wanted to mimic the process of daydreaming on a car ride, where external input and inner monologue can mix.

I wasn’t planning on posting it yet, so I’ll have to get you a thorough follow up, but in a nutshell it’s: a continuously running 448-concept space (philosophy, cognition, art, nature, math) that occasionally “crystallizes” a group of 4 concepts via Hebbian learning and stochastic noise. Those concepts get sent to the LLM with minimal guidance beyond some safety guardrails and encouragement to be creative. It has access to a sandbox to produce essays, stories, music, “art”, and small python scripts. Self-updating memory system. Notes, essays, and artifacts can also be discussed with me through some outbox channels.

On top of that it’s got a separate academic philosopher + psychiatrist llm that critiques its work and has a regular cadence of “sessions” with it, as well as a research assistant bot who I talk to (but doesn’t interact with Sisuon) who has full project context and memory access. The sisuonspeaks site is a VERY abridged collection of Sisuon’s essays, along with analysis, commentary, forum posts, and a podcast…all created by, you guessed it, more LLMs.

I've always wanted my own VW diagnostic tool suite, and between tooling that was released in public on GitHub (https://github.com/kartoffelpflanze/ODIS-project-explorer) and my own research from years ago, it always seemed straightforward but too tedious to execute on. Claude did a great job making something useful, https://github.com/bri3d/mcd-diag-rs , and now I don't have to find a Windows machine or remember a specific diagnostic cable to replace my brake pads.

I also build a ton of household glue stuff; I was never really passionate enough about the whole "homeserver" thing to spend the effort in going beyond basic video recording for my security system, but now I have all of my local-only home automation stuff wired together, mostly into HomeKit, and have been able to ditch a ton of cloud services.

zytek• 1 month ago

elaborate on the home automation pls

bri3d2• 1 month ago

I used the usual stack of HomeAssistant, Frigate, and a bazillion glue connectors to consolidate devices that were previously cloud apps on my phone.

For example, previously I used the Frigate web UI over VPN to access my cameras, but I instead had Claude help set up go2rtc to push the video to HomeKit. I used the Eufy app for my doorbell, which I was instead able to integrate into HomeAssistant and then push to HomeKit as well, and I was also able to integrate some TP-Link Kasa plugs with HomeAssistant too.

This is all stuff I could have done relatively easily myself, but I hate nothing more than wading through horribly documented disparate configuration systems (I do that enough all day), so having Claude to do it for me is what unlocked it actually getting done.

I also added on to some custom one-offs like an ESP32-based controller for my kid's RGB LED nightlight for fun, although that stuff was more hand-coded since I find it enjoyable.

An active learning loop for a model to clean up articles by removing junk like native ads and sponsored blocks.

A tabbed terminal with project management features like launching the database, app server, and claude code in different tabs with one click, and split browser/terminal panes (eg. opening a browser automatically at the correct URL when the terminal reads http://localhost:4000/).

A modular MCP server with a MCP proxy and OAuth2 dcr so that I can easily add new random ideas for MCP servers in a few minutes with Claude and deploy them such that it's available to Claude by refreshing the tool list.

A small tool to render Claude conversations so that I can link to them from my obsidian vault with something like convo://claude-code/-home-jfim-projects-foo/<guide>

A "Home Agent" setup, with customized special agents to manage various aspects of the house through home assistant, learning feedback from household users to try and tune everything at the right time.

Various MCPs for above.

A "remote claude code server", that gives project level overview and lets me run projects / develop on my home server rather than locally through my laptop. Supports ssh as well as a web UI (projects in a list, shell rendered using https://xtermjs.org/, with a tile overview when working on multiple projects to watch for turn ends.

Similar to above, I have a local version that auto launches a new project scoped podman container, passess through the work directory, installs CC/Codex/Grok into it and passess through the auth / config for each agent. Then dumps you into that shell with aliases to map each agent to that agent with a few special env flags to disable permission prompts, so claude = `claude --dangerously-bypass-permissions`.

An extensive MCP for Obsidian that gives agents access to use a lot of the more advanced Obsidian functionality, such as suggesting and installing plugins / configs / etc.

It's helped some of my daily productivity, but I still prefer to get my hands dirty with code most of the time rather than full prompt it.

I didn't build tools in the classic sense of something you build and run semi permanently, like baked into your setup or home server or whatnot; but I found myself building bespoke tools with most new projects at work. Get a new Jira ticket, figure out which components will be involved, often times the tool goes collecting logs and parsing them into a Web UI with buttons to toggle various features or params. And it tends to be different for every project. It's like the oldschool shell oneliners but more powerful and easier to write.

And serve as an ops "point of contact" for other agents for the machine / fleet of machines it’s in charge of.

The most comprehensive tool I've built so far was a JSONPath playground [0] when I was working on a game where I found myself writing a fair bit of JSONPath (well, JSONPath Plus specifically) expressions by hand and wanted to be able to test them out in the same way that I would on regex101 when writing regular expressions.

I realistically probably would have only saved myself less than an hour of crafting those expressions if the tool had already existed (with this level of detail, there are lots of many simpler ones already for it), but I would have spent a solid 40-50 hours of bouncing between manually crafting and writing detailed instructions to direct the agents to get this tool there.

I've made 3 that use pi as the primary interaction, with custom tools and scripts.

1. family tree based on wikitree format. Transcribe records, verify/edit, then incorporate them into the tree with full citations and biographies. This one is the big one. It includes a tree browser and best genealogical practices.

2. Pool Math replacement. Log pool chemistry tests to markdown files and suggest the right amount of chemicals to balance.

3. Calorie counter. Log calories to a markdown file, look up foods and amounts in online databases, sync with garmin connect for exercise calories.

All of these are written with AI but also are interacting with pi and telegram, mostly using deepseek v4 flash.

I made a golang socks5 proxy that routes traffic to different VPSes (or the default gateway) based on hostname, over mutual-TLS tunnels, authenticated using ed25519 keypairs shared out-of-band. The "client" and the "server" are the same piece of software, and there's a web UI for configuring the routes.

I made it to deal with internet censorship in the UK, where different sites have different optimal exit jurisdictions, and most sites work fine so I can avoid the extra hops where possible.

It also works well for video streaming sites with geofencing, since the geofence itself is usually implemented in the frontend rather than the CDN. So only the frontend traffic needs to be proxied, while the bulk CDN traffic doesn't need proxying at all.

Socks5 is the ideal layer for hostname-based routing, since the proxy can see DNS names without needing to sniff TLS SNI (which would be incompatible with ESNI/ECH etc.)

iirc it was basically all done in a single prompt, and I've been using it ever since. The only issue I've encountered is with WebRTC not working properly with some services. (Presumably it breaks the NAT holepunching process or something, I never diagnosed it)

Another project that isn't quite finished is a "universal" web video downloader that works by shimming the MSE APIs and remuxing the streamed segments back into a regular video file. The idea is that if you can watch it, you can save it - including but not limited to youtube videos. I started this one pre-AI but AI was a huge help with the container format wrangling.

I wrote my own Claude Code agent. It leverages some parts of multiple different agent stacks but using my architecture. It's layered, has long-term memory, agency to expand upon work, access to linear, access to all the models and endpoints you could possibly wish, as well as support for combining multiple providers and models into the layers so that delegation to the workers happen on the cheaper, more cost effective models. All of this runs at scale in an orchestration platform I wrote, using said agent, to create a cluster of docker containers in a JBYOS configuration, cross-cloud, k8s or swarm or whatever can run docker. It's pretty sweet and is basically an AI software development shop. I only have to give it ideas and goals.

unholiness• 1 month ago

As the 36 millionth person building something similar, I wish[0] there were better info out there on what works well. I can understand why, but it's still frustrating seeing on the one hand how deeply helpful the flywheel of this type of setup can be, and on the other hand how every blog post stops at some incredibly superficial setup to help them write more blog posts.

[0] Yes this is a plea, if anyone has the good stuff

reactordev2• 1 month ago

Here's what I did, roughly, YMMV. I have a lot of experience in managing scale and web platforms as it's what I did for like a decade so, grain of salt and all. Let's assume you have access to N number of linux machines with GPU's, for the sake of argument.

I have a small RPI acting as my homelab pihole and dns so what better than to run the management UI on?! So I wrote a small bun management plane, nothing fancy, just a react app with user auth + openidconnect for those that like that stuff. From there, you have compute pool (empty at the moment because it requires a deployed agent). I added the ability to directly ssh into a machine, install the "agent" with privilege so it can manage docker, and the agent talks back to the management plane over websockets. A keep alive / health / status / resource packet every 15 seconds. Streams if you are looking at logs or accessing a container. I used Codex for most of this work but defined the protocol and everything upfront using protobuf (even though it's websockets). It helped with the "vision" and keeping the agent like Codex on the rails through completion.

Once you have a pool (agents installed on your N number of linux machines), you can deploy apps (which are my way of saying, a container with a namespace) or you can deploy agents (which is my agent, custom made for this) that are assigned to a project. I decided Org structures are a great way to delegate workloads so that's how they are modeled. Projects provide the git repo, the docker registry for images and storage of artifacts, as well as the history of all the prompts the agents have done in the project. Useful if you want to go back and search through |thinking| tags to figure out the reasoning behind a decision.

All of this was built in like maybe a month with Codex initially, until my agent was up to the task of coding w/ an endpoint configured (OpenAI API initially, now, NVidia DGX Sparks). What really works well is the delegation. The agent's have a webui that is exposed via the project urls so you can interact with the "scrum masters" of each project. They also share a stream if they are on the same project (but different subprojects).

I too wish there was more information on this but I didn't keep the lack of it from stopping me experimenting and finding what works. I came from the Mesos/DCOS era where you stop thinking about the metal and think in pools of resources. It's a distributed systems problem.

I finally shipped a Chinese learning app I wanted for myself for ages at https://wenmoji.com/. Just never had enough time to sit down and code it end to end. Still need some improvements of course, but will slowly chip away on it. I use it daily/weekly myself now.

Highlights are that it completely free, no login required and works offline (once you "downloaded"/cached some files the first time around).

shibel2• 1 month ago

I need to finish off that blog post.

With Tailscale, you can basically point a domain to the FQDN of a machine you’re sharing with people and the domain will simply work for them (and only them)[1]. But for it to work without them having to know or specify the specific application port, you have to grant them access to 443 (and 80) in your Tailscale ACL for that specific host.

So yeah, now immich.familydomain.com works without family members having to remember the specific port. BUT, serveradmin.familydomain.com (another app on the same host) will ALSO be accessible to them (from a networking POV). We opened port 443/80 for that host after all.

I took a few hours with Claude back in January (?) and we wrote a tiny Go authorization gateway which basically consults both Tailscale’s public API and Tailscale’s `localapi` and returns the appropriate response to Caddy based on the requesting user’s actual allowed ports.

So now I can share different apps (subdomains) with different people without forfeiting access controls, all driven by Tailscale’s policy file.

(I hope I didn’t mess up the crux of it, pretty late here)

Edit: why not (something like) Authentik? Quoting from the draft:

  I contemplated this for a bit but one thing I kept thinking about is:

  _They're already logged in to Tailscale_

  Why do I need to install and configure another full-blown app dedicated to doing something Tailscale already did? Why have the users go through two hops of authentication?”

abeyer• 1 month ago

authentik is also an oidc provider... couldn't it also be the way they auth to tailscale too?

shibel2• 1 month ago

Maybe…I really didn’t want to have to install another app just because I’m sharing though. My line of thinking was/is:

If tomorrow I decide not to share with anyone, I don’t want to have to reconfigure stuff. I simply edit the Tailscale policy file, and (maybe) spin down my server.

Pangolin would have been a better direct fit than Authentik. It does come with an embedded idP nowadays but can also use Authentik. Another tool to keep an eye on is Netbird which is like a tailscale like mesh but has proxy support for whatever app you want to share with or without authentication.

I built a browser extension that stops animated images such as GIFs by default.

I've always found it annoying that browsers autoplay animated images, and there still isn't a built-in way to control that behavior.

The extension shows the first frame and adds a play/stop button directly on the image.

What started as a personal utility ended up being published on the Firefox and Chrome extension stores. It's still a small project, but it solved a problem I had every day.

Firefox: https://addons.mozilla.org/en-US/firefox/addon/gif-control/

When I first started daily driving Linux in 2011, this was the default behavior of konqueror, Firefox, librewolf, and opera.

I would have to set a flag in the software to get it to autoplay videos and gifs. They would just load with a warning message in the render space that said click to load auto play video.

Not surprised that it’s gone.

I wired up a stream deck to perform long-running tasks. Very much tailored to the kind of HCI that I prefer, so I can be interrupt driven versus checking on status all the time.

Eg: push a button, it shows that it's working for a while, then strongly flashes when it's done (success/failure). When you have it right under the monitor, it's like a macro pad for long-running things.

This reminds me of some of the very early peripherals you'd see on the Alto and other computers. I was surprised something like this didn't seem to exist, but maybe I'm just terrible at searching.

Workflow:

Built a meeting-intelligence pipeline that turns raw, error-prone transcripts into a structured, queryable knowledge base. Meetings get auto-transcribed by Krisp, whose speech recognition mangles the things I most need correct, like colleague names, customer names, internal product and architecture terms. I hand each transcript to Claude alongside a hand-built context document, and it works a fixed routine: read the context file, read the transcript, then reconcile every uncertain name or term against a master error table before drafting anything. Only the genuinely unresolvable handful surface as questions; everything else is corrected silently. Once I confirm those, it emits a cleanly formatted markdown summary in a manner I describe as a template: overview, topical notes, decisions, action items — and pushes the work items into Todoist so commitments don't get lost.

What makes it more than transcription cleanup is the back end and the feedback loop. Each summary hits Obsidian with YAML frontmatter and live Dataview queries, so open action items and meeting metadata behave like a database rather than static notes. In Cowork the whole accumulated Obsidian folder becomes fully queryable rather than merely searchable — instead of grep-ing for a keyword, I can ask questions that reason across months of meetings ("what were Todd's table-stakes asks, and has anything shipped against them"), with the model able to look across separate conversations. The other half is self-improvement: every clarification I resolve gets written back into the context document: its people directory, terminology glossary, and especially the ASR error table, so a garble I corrected once is corrected automatically from then on. Over time that one document has become a domain-tuned lens, and each meeting both draws on it and sharpens it, which is why the summaries keep getting tighter and need less of my intervention.

Beyond that: I use a Netatmo weather station which has a RESTful API (or sends to a cloud server that has one) - I pull that information (which I can see on the web and their apps) into my own VictoriaMetrics / Grafana set up on Kubernetes, via a Go app Claude built.

This app above was when I had my little aha moment: Netatmo's OAuth is slightly broken (issues with the different tokens and refresh). But I'd written a dog-ugly app which managed to work a while ago. Claude kept trying and strugglign to understand why its OAuth code wasn't working, and was asking me "are the credentials right?" etc. "Yup, I'm able to get data from my old app", then it said "If you have the source code to that app, I can figure out what's up", it looked, identified the issue, tried to work around it and then we "agreed" - "Hey, this should work this way, but it doesn't, and whether my old OAuth code should work or not, it does, so drop that in, and keep going". "Great, let's do that."

I've always felt like I'm implementing the same high level design in any language I've worked with, it's just manifested and looked different, depending on the language tooling. The "good" opinions are baked into the _structure_ of the language itself, so the robots have no choice but to build well designed codebases.

And more, and that's just what I did for making my life easier, there are other more "enterprisey" things I am working on. They're web apps that I add to my iphone desktop or run on otherwise junky old tablets or on TVs.

The point is that they do exactly what I want them to do instead of relying on downloaded apps that get me 80-90% of the way there, even if they'd be classified as "AI slop". I know enough about security and caching that they aren't full of holes and don't kill upstream, but I don't really care about the code, and it's literally easier for me to build something new than to go to Google or an app store to find software that's full of ads.

Countless little things to clean up data or improve tools I wrote long ago. If you count HomeAssistant things (via MCP) then many many more little qol things, too.

Most recently, though, is a basic python CLI/Flask app that makes it point-click to manipulate the route table and dnsmasq settings on a raspberry pi. eth0 on the pi goes to LAN and put a USB ethernet attached to a switch and you now have a pretty powerful IoT/Untrusted device inspection environment.

One click to change the DHCP settings offered to the device, run a pcap, allow/deny the device access to certain services or NAT them elsewhere as needed. Straight forward DNS adjustments that can be applied per device and now that MITM-Proxy has a python API... it's pretty straight forward to also peep inside of SSL protected things.

Quite a few during the early days. Recreating some fun ‘game’, popular during the Flash days. A work breaker/silencer, etc.

Then, I got bored because they seem to be bad beyond certain complexities. But around Christmas last year, things improved a lot, and I’m getting confident building real ones. In the mid of these, I also got an offer to work with the [pre]sales/GTM team of a large company. So, I have been building working prototypes of bits and pieces of boring enterprise business around the world and have been racking in, if not billions, but very close to it in sales pipeline in about two months. (I did that 1B token in a week thing.) I’m sure the business and sales team will be able to convert 20% to 30% of that in the coming months. I also pitch and presented my work directly to customers and they are coming for more. So, it has been fun.

Lastly, I really wanted to scratch an itch I had for a while—build a Static Site Builder. But I ended up buildig it to be a documentation tool for TypeScript and JavaScript. It can be used as an auto-detect and let it build alongside front-end projects, make it a hybrid so you can add human-written documentation too or just build a Jekyll-esque static site.

So bpm, pitch, song metadata etc. The tool also connects to my recordbox library and runs custom ML algos to classify for pitch, stems, tonality Phrasing, energy etc. Long story short it basically shows me ideas of what will mix in well. It works bizarrely well for me.

if you have all of that info, could you then automate the mix transitions by sending MIDI commands back in? would be fun to play a playlist or radio but where the track transitions are automated, phrase-matched and non-trivial (perhaps lasting for a number of phrases)

ilikeatari3• 1 month ago

Yes! I think so. It was not my usecase as my goal was to actually still be in control of DJing myself. I just wanted good candidates for mixes. But I wanted to still be in the loop to have fun just playing.

I got tired of all the quirks when opening CSV files in Excel, so I built a fast and lean viewer for CSV - at least this was what initially planned.

Later I find the technique I developed to instantly load arbitrary large CSV files can be generalized to work with any format, with an incremental parser combinator. This means the tool can read from not only files, but any stream-oriented sources like a pipe.

I did used AI in development but it didn't speed up the process very much, as I found a lot of time was spent on the deign of an intuitive and consistent UX. The project is still not very production ready, but in case anyone is interested: https://github.com/Verticalysis/Hitomi

I get annoyed that existing tools have limitations so I fix them or build my own:

- I didn't like that I can't use my newsreader on my laptop and my phone as easily so I built https://github.com/mjc/nntp-proxy. that turned out to be really hard to benchmark once it got fast enough so I am working on an nntp benchmark tool https://github.com/mjc/nntpbench. both can do request queuing because the nntp RFC says servers have to accept as many requests as they can, and then process them in order. so if your client doesn't do that, you can use more connections to the proxy and it will queue for you. it also routes stateless commands to whatever server is least-loaded, and will switch to stateful mode if your client needs it.

- I didn't like how expensive AWS Transfer Family is, so I built this https://github.com/elixir-ssh/sftpd and then rewrote it in rust (alpha) https://github.com/mjc/sftp-s3-rs. this shook out a bunch of bugs in russh, which was fun. - didn't like that there's no par2 implementation in rust so I built this https://github.com/mjc/par2rs (I'm too lazy to move to tape backup so it works pretty ok for dvd/bluray parity), unfinished but good enough for my use. - same deal for 7zip in rust. https://github.com/mjc/r7z - a medication tracker thing that uses claude/codex/copilot to scan the bottles and parse them as well as identify pills etc. works better than you'd think but I'm not planning on releasing it for a while.

fixed or fixing bugs in: - exqlite (it should not crash anymore and should return busy a lot less often.) - russh - swift-nio-ssh (this might be why codex's remote can't connect to your ssh box) https://github.com/apple/swift-nio-ssh/pull/236 - NanoKVM (working on making the streaming for this a lot more fluid)

I built https://beachcomber.sh after one day getting huge lag and asking claude to investigate found that one of the factors was thousands of resources purely for giving my prompt, tmux statusline, nvim statusline, claude statusline the same identical information.

I probably would not have bothered to allocate time to this pre ai, the juice wasnt really worth the squeeze. But I approached it with an initial amusing naivete about it being 'super simple'. As is almost always the case with software theres a reasonable amount of hidden complexity. But I have been using it as a sort of learning proving ground for how to work with agentic development. For example I got to a point where claude wouldnt implement properly and would argue with me about changes because it would read the current/old docs in the repo and get confused about reality. So right now I'm experimenting with 'canonical specs' that can only be changed modally with gates and a defined cascade from canon, to code, to docs in that order. Otherwise you end up in a weird thrash about the docs and the code disagree and which one will the agent decide to change for consistency?

Anyway, its been interesting and its v0.6 and at a point where Ive not hit a sharp edge dogfooding for a while and some beta testers would be valuable. Right now you have to manually wire it into your stack, once some others have kicked the tyres hard enough I will make some pr's to the popular tools to consider integrating it.

You are correct: git 2.54 supports multiple hooks via a the git repo and global configuration files.

Git-multi-hook predates that, but I updated it to use the new 2.54 config-based format.

The significant advantage of git-multi-hook is that they all run in parallel. I run eight hooks on precommit, so parallelism is a big win.

I made myself a silly ai-chungus it works as a series of containers that communicate over mqtt. I have an ollama shim for other services to talk to a model on my other machine, telegram shim that acts as a ui, a study component that will give me a random subject for me to study over the course of a week and I give a proper implementation (let’s say a ring buffer) and it reviews the code I wrote. It has some minor gen things using comfyui like a card pull system with cards, card text, rarity system, and special card effects like holo. And my favorite bit has been tying my todo system into it so I have a thermal receipt printer which will print a task I have to do for the day, prints a barcode, and when I finish the task I scan it with an iOS shortcut. It’s beautiful. What’s been the most fun was designing the mqtt topics in a way that makes everything else flow perfectly. Oh and there’s a tts system that uses kitten-tts which will produce audio for certain messages and an esp32 that gets those sound files and plays them on a speaker, or I can play the messages on telegram. Like if I do an /overview command on telegram i get an overview of my incomplete tasks and the ollama model helps prioritize. It’s my favorite use of ai junk at the moment

andai3• 1 month ago

This is great, you should do a write up. With photos!

Can you explain the study thing in more detail? Or give an example of how you use it?

lovehashbrowns2• 1 month ago

Sure so there’s a command in telegram you do /study and you can either tell it a subject or it’ll randomly generate one. I did /study ring buffers last time. So then opencode / GLM 5.1 or whatever write an entire site for me explaining the concepts, tradeoffs between things like infinite read write pointers, memory mirroring, how to tell if the writer looped the reader when the pointers are not monotonically increasing and instead get modulo’d, and bit masking with powers of 2 etc etc. then it wrote a ring buffer with various features in pseudo code so I can’t cheat. I also got papers to read from ACM and such. So I pickled it all over a week and came back with an Odin implementation, submitted to the site running on docker, and the ai reviewed it for me, telling me mistakes I made or areas where code isn’t really professional or I missed something. It’s genuinely super helpful. And the idea is whatever the AI tells me isn’t my only source of info so for example if the ai says infinitely increasing pointers will overflow but for example if I’m using Python, Python integers are basically bounded by memory and practically on most systems “infinite” so shut up AI I can do that or if it gives wrong info about something I’m getting published journals or websites as reading material that (hopefully lol) isn’t hallucinated. But really it’s the classic college style learn it then do a lab type of loop. Except it’s topics I’m genuinely interested in in the moment so the energy flows perfectly into it. My only wish would be to have it be cooperative working actively with others for the more accurate college experience bouncing ideas off other people seeing where we’re all confused or just me etc

The idea is to make distracting sites less appealing, without using a black-and-white site blocker, which you can easily disable.

I've got really comfy `just` scripts for generating Clang "intermediaries" in my CMake project. I can generate `.ii` files which get formatted and edited in a manner making them directly recompilable, along with `.ll`, `.bc`, and `.s` files. All the above are per-translation unit or post-LTO and I can constrain the output to specific functions or files, and the LLVM bitcode can take optimization passes or optimization levels to very easily introspect how my work in this codebase optimizes.

I've also got a clang-repl wrapper for this codebase that is very easy to use and makes interactive programming much easier for me.

I've used AI for a number of Emacs-related utilities and configs. Just today I created a script to reproduce the particular combination of MSYS2 packages I use for my newer on Windows setup - the hard part being to get native comp working. Small, but it's the sort of rarely used convenience I wouldn't have written up in the past.

Also I had a redis clone from before, but with AI i separated the epoll layer from the actual database engine which made it sort of embeddable. And hooked that embeddable database into a JNI interface, and now it can run inside Android applications, sort of like a concurrent hash map, but one that lives off heap and has support for TTLs and mget, msel, mdel, hashes and all that. I use it for some silly android games.

Before agentic coding went mainstream, one of my main use cases was creating sticker designs for concerts and music festivals. Creating the stickers and giving them away was a good way to meet new people.

I used OpenClaw to make a health and wellness coach agent that tracks calories and alcoholic drinks and logs it to a personal dashboard. I send it photos of my meals, and it will estimate the calories and log it. It will also help me make meal decisions and give me words of encouragement.

I used this HAM dashboard git repo to create a bespoke dashboard of different video and weather feeds from my area: https://github.com/VA3HDL/hamdashboard

I also, in the same rabbit hole, created a radio reference guide for the Sonoma County area: https://mybbor.com/petaluma-sonoma-ham-radio.html

I don't do a ton of programming on my own time to be honest. But I did make some recipes with Calibre. Seeing Gemini basically jsut take the HTML from some news Web sites and come up with recipes really opened my eyes to how good that stuff had gotten.

Jordan-117• 1 month ago

Gemini has been indispensable for helping me move from Windows to Linux. I'm reasonably proficient, but moving to a brand-new OS brought so many random questions and weird edge cases that I never would have had the confidence, patience, or time to tackle it alone, even with pretty strong Google fu. It's been so nice to have instant access to answers for my specific problems, without judgment or having to wait on a reply.

At the same time, I moved from Chrome back to Firefox, and Gemini was great at finding equivalents for my most-used extensions -- and, when none existed, to write my own. It's also been really useful for customization/"ricing".

More recently, I got into Quod Libet as a primary music library manager, and both Gemini and Claude have been fantastic at helping me build custom plugins that make it do exactly what I want it to. Scripts to automagically download tracks with metadata and synced lyrics, a lyrics sidebar that highlights lines as you listen and lets you click to jump to a specific line, a bookmark button that lets you mark your favorite section of a track for easy browsing later. Next chance I get is something that enables lyrics search across the entire library (a feature I was already able to build for the Stremio desktop player -- it's so cool to be able to search for a line in a TV episode or movie and jump straight to it).

For me that’s killer feature, even if we don’t achieve AGI at least we got good enough „something that will google it for me”.

It is great both ways as an expert in my niche I don’t have to waste time on reading through entry level fluff. As non expert in other fields I don’t get to be scolded for asking entry level questions so RTFM and LMGTFY will sink in history fortunately.

A "plans for agents" interface because I'm tired of reading huge markdown plans to iterate on the real work. Is supports infinite 2d space like miro, but has one thread per card, a cli for the agent to treat open notes. It support voice prompting too.

It feels like you have parallel conversation with an agent, except it understands all the surface. And it's granular, surgical and precise.

Usage: I'm writing a game design document of 70 pages with it, working surgically without having to worry about what page number the edit was.

It really solved my main bottleneck which is telling the AI what to do in a complete and comprehensive context.

Readme is trash but your agent will understand what to do

michaelteter• 1 month ago

TONS of tools. Most written in Go. Several have API servers in addition to cli or TUI or web interfaces. The API interface to my apps makes LLM-driven development much faster.

https://github.com/michaelteter/docgen : create a single text file of your entire project, with a tree and some other useful bits. This is good for dropping into an LLM or research notebook instead of giving an LLM access to your actual project folder. It also can be put in your pre-commit script so you always have one single doc you can diff from one commit to the next.

md2pdf: markdown to PDF, relying on defaults and optional config files or cli args for formatting choices (such as page margins)

md2gslides: markdown, converted into slides, and using Google Slides API to generate the doc in my Google Drive. This saves me so much effort (I teach, so I make lesson plans/presentations all the time).

get-music: TUI app that lets me search Youtube and easily queue up to download one or more of the search results. Then I take the downloaded content, split out the audio, LLM process the video title, add metadata for music, and then provide an easy command interface for local searches and playback of downloaded content.

bookmarks: TUI for slurping all the URLs from my browser, LLM-tagging each url based on the tag list I provide with the prompt and url, and lots of features for managing priority, show/hide tags, etc. This was to help me stop worrying about having a hundred tabs open. Now I can just sweep them up into my own private, encrypted (sqlite) db.

ESL-Planner: Complete web app for building class plans for teaching English (based on params, such as student age range, skill level, specific teaching language (what we want to teach), etc. It's close to being ready to productize and release as SaaS, but I built it for myself initially.

Numerous other tools plus a guide doc listing all the tools and what they do. These resources are then made available to LLMs when I'm developing, saving me (and the LLM) the time of hand-crafting the same tooling over and over.

After dropping the keyboard for the TV one too many times, the touchpad stopped working.

I looked for a decent remote keyboard app to use on the tablet, and found nothing I liked.

I ended up asking an AI to make something that served a webpage that connected back to itself via websockets. It provided a keyboard and touchpad on the webpage and forwarded events to uinput.

It works well enough on tablet and phone that I haven't got around to replacing the original keyboard.

My favourite football team was really at risk of relegation, then I created for me and my friends an MCMC bayesian simulator to estimate the relegation match by match. It was an opportunity to get used in real life to some concepts (MCMC, Metropolis-Hastings, etc) that I always struggled to understand. And my team got saved from relegation with an amounts of points very close to the number of points that my model forecasted

I also wrote an honeypot that emulate an Ollama instance: beside the attackers, it's funny how many people are looking for free inference. Somebody from Brazil try to use my honeypot to write to chapters of a book about traditional magic rituals. My next step is to extract the data collected by this tool to extract IoC and malicious prompts and share them with the community.

CodeMerger: https://codemerger.nl I've never liked the lack of control I feel using agents or tools like Cursor or Antigravity. I found myself having much better results simply pasting full source code in free chat, so I built a tool around that philosophy and I've been exclusively developing with it for a year now. It includes a Project Starter and code architecture analysis tool.

Presentable: a photo library sorter with Ai powered organization assistance, a compare canvas with various viewing modes and customizable folder sorting shortcut templates (wip).

AlwaysWhisper: a tool that let's me attach STT to my entire OS, with custom wrappers for different programs, adding theoretical voice control to any software (wip).

ScreenLoader: an Electron based tool that can load any web source as a kiosk app, full of useful features like keep-alive, covering multiple screens and tracking output logs.

Inputboard: a unified all-inputs hardware board, that transfers input data to any prototype I want to work on using an optocoupler, so I won't have to fiddle around with setting up clean and reliable inputs from cheap Chinese components every time I just want to test something.

Squire: an agentic board game helper, that can ingest a manual and will hopefully help decrease the time spent on endless discussions about seemingly conflicting rules. It should also be able to help me play a game when I don't fully understand the rules myself yet (wip).

NodeRunner: an agent that plays the WikiGame, focusing on speed, efficiency and token usage (the result of a fun competition with a colleague).

Sonic Bloom: more of an experiment than a tool. It's a wireless piece of custom hardware, that listens to conversations, sends data to an LLM through fast STT and returns a color choice that matches the topic being discussed to the hardware, which then controls an LED ring. It also has a small display that explains the logic behind the color choice.

Image-to-story: a VLM tool that kickstarts a written story using an image and has some rudimentary tools to expand on it based on user instructions (wip).

At-work-or-not: and Android app/website where colleagues can check if I'm working from home, if I'll be at the office or if I'm not working at all. Also doubles as a private record for tracking transport expenses.

SharedMaps: a Maps based website where groups of people can share custom categories of geo locations and drop comments on them.

VMG: an image format that includes audio with images and offers TTS input to easily add narration.

Who wants Coffee: a small Android app to help me remember who wants to drink what when I go for a round at the office.

And a pile of Python scripts for smaller useful tasks.

My favorite is: https://github.com/theo-sardin/instant-switcher

Instant windows switcher with custom shortcuts and instant "opt+tab" and trackpad switching. Simple does exactly what I need it to do (just bypasses the slow window switching that is annoying), with no additional features or bloat.

I've also done a TUI that combines my messages from WhatsApp + messenger + discord which is pretty handy at work.

mateioo7• 1 month ago

Cool stuff. What do you use to get new messages from those 3 apps?

elar_verole2• 1 month ago

Several things:

https://github.com/openclaw/wacli for WhatsApp,

https://github.com/diamondburned/arikawa for discord, and

https://github.com/mautrix/meta for messenger.

There was a bit of initial setup extracting tokens for messenger and discord I believe, but now it's smooth sailing. Some issues sometimes correctly mapping ids to usernames / convos make it so some conversations are duplicated for messenger, but when I have time I think some smart reconciliation heuristic will be able to take care of it.

It's great !

One of the "huh, didn't expect that to work" moment was getting GLM 5 to make me a user space driver for the Nintendo Switch Pro 2 Controller on Ubuntu.

When you plug it in, the device is recognised, but press any button and it attempts to start the pairing process. Then using evtest nothing is coming through.

That^ was pretty much my prompt too, and 10 minutes later I have a working driver with systemd unit so it works through restarts. Amazing stuff!

I built a route planner. I walk around the city where I live a lot and love exploring new streets, but at some point it became difficult to plan routes through streets I hadn’t walked down yet, so I created an app that lets you plan different types of routes. You can specify the percentage of overlap with streets you’ve already traveled, create a route from point A to point B, a circular route, or a one-way route. You can add streets to your favorites or exclude them. The app runs only on my local computer. I use it all the time.

lionkor• 1 month ago

A website that tracks when we last went on a weekend trip and other kinds of things, and reminds us with a cute friendly (not AI written) email when it's time to plan something again!

It really helps us to not forget to spend significant time with each other when life is busy.

A rant follows.

I've generated probably as many lines of code by this point as I've written myself over the past 5 years or so.

I found AI generated code mostly very frustrating, kind of low quality in its own way, and too complex. I have pages and pages of instructions to guide the agent(s) to do a better job at this, and it has gotten better, but the fundamental limit of this technology is tangible.

Like, okay, CPUs still get faster every year, and every now and then someone makes a breakthrough and we get a bump in speed from something. But when you write high performance code, you very quickly run into hardware constraints, like how fast information can move and how far away components are from the CPU cores themselves. People keep saying performance isn't THAT important, and that modern hardware is so fast and amazing, and that they struggle to even find a way to use all of their CPU cores and RAM with their little app or program or game. Yet here I am, writing code that will noticably speed up if I run it on a CPU with a little bit more L1 cache.

This is similar to how it feels to program with AI when you're reasonably competent (to put it mildly; I avoid the 10x developer label because comparison to others is very silly). Everyone keeps saying it's getting so much better, and it's so good, and worrying about code quality and architecture is dumb because we can move so fast it doesn't matter. Yet here I am, writing code by hand because I tried doing it with AI a couple times and it just doesn't hit the mark.

I'm not doing anything special, I just have high standards and a good amount of experience when it comes to software quality, performance, and maintainability, which is why I keep getting hired. I'm convinced that people who think their AI generated software is good are the same people who write short variable names and think it makes their software faster (hyperbole, but you get what I mean).

I can feel when I hit the limits of the hardware, and I can feel when I hit the limits of LLMs, and I know for both of them that a 2x increase in performance will not change what is and isn't physically possible.

Now obsidian works for me like I want, and still every day I use it Im still in awe

I was always experimenting with different agents and models, and I wanted to track how much I use eg codex vs opencode vs hermes, and which models I use.

So I made, kind of last.fm/waka-code for agents where I track (anonymous) usage per project

Data is fully anonymous, all I collect is (agent, model, project name [can be mapped to something else to hide the true name]) and everything is opt-in by default (per project)

Hi HN, I built (yet another) webapp (PWA) for looking up guitar scales and a bunch of other tools.

https://guitar-tools.eejalab.xyz/

There are plenty of other tools already that do this but hopefully this one adds some quality of life niceties such as dark mode and a mobile responsive design that seems nicer to use than the others out there.

Hope the colours look ok. I'm a colour blind person (deuteranomaly) and I've optimised it for what looks good to me. Am open to adding a mode in line with what regular vision people might prefer.

No frameworks used, vanilla JS. No sign ups. Data/state persistence is purely local storage.

Absolutely no commercial interest here. Built this purely for the love of it. Will forever be free.

- RockstarNinja, for sharing Claude plans and sessions. Since it's a bit of a data hog signups are limited, but me and my cofounder use it all the time: https://rockstar.ninja

- TweetEmbed, for browsing an offline Twitter archive and getting self-contained HTML copy/paste-able cards: https://duggan.github.io/tweetembed/

- bewitch, a terminal based metrics collector and data visualization system: https://bewitch.dev/

Each one of these has been a great way to really push on automating build processes, see what Claude can do for automatic documentation (screen captures, etc), and trying to give a distinct visual identity. In my next project, I'm trying to de-LLMify the prose it generates by using my own blog posts and aggressively pruning and integrating into the prompt.

The biggest change has just been unlearning "cost". Stuff I've subconsciously shied away from since intuition built up over a career has given me a sense of how long things take that just isn't true anymore. Still learning!

ReverseCam - A camera app to show the non-mirror preview while taking selfies.

https://www.reversecam.com/

The front camera apps always show the mirror preview. Most of us hate photos others take of us, but love our selfies. It's because we groom ourselves and find our perfect angles using the mirror preview. So it's jarring when we see the photos of us taken by others. I always wanted a camera app that showed the non-mirror preview. Surprisingly most camera apps don't have this option. So I created this app to scratch my own itch:)

Note: Photos and videos are only stored in the browser. No data is sent to any servers. You can also install this as an app from your browser since it's a progressive web app.

a TUI that runs all my daily Linux updates from one place.

Updating my machine used to be a dozen scattered commands: apt, fwupd, and a pile of dev tools I want kept current (node/npm, go, claude, opencode, plus binaries like kitty and lazydocker) that each update their own weird way. Now it's one Bubble Tea dashboard that checks each tool's installed version against upstream and only downloads what's actually behind, so I can see at a glance what's current and what's not. Adding a new tool is easy enough that I just toss new ones in as I start using them.

It also has a cleanup mode that hunts down all the pesky cache files that quietly eat your disk and reclaims the space in one pass, which has saved me from the "laptop full again" scramble more than once.

Currently, testing it privately and tweaking to make it awesome.

Another tool I made for myself is automated video editor (takes folder of raw photos images, and generates edited video that can be shared online). Used it among other things to edit all my GoPro raw footage laying around (hundreds of files).

Vibed a ton of small projects, mostly for my own usage, to understand what agents could do, or just to satisfy my curiosity. Most are rough around the edges, and a bunch quickly became obsolete as agents got better and I stopped using them.

Browser emulators / games

https://nesvibes.tsilva.eu/ — Browser JavaScript NES emulator in ~2.5k LOC

https://scummweb.tsilva.eu/ — Run ScummVM games directly in the browser

https://github.com/tsilva/REFramework-chill — Anti-nausea improvements for Praydog’s Resident Evil VR mod, specifically for Resident Evil 7: movement vignette, snap turning, etc. WIP.

AI / ML browser experiments

https://llame.tsilva.eu/ — Run small LLMs in the browser with WebGPU

https://aipit.tsilva.eu/ — Debate simulator: pit simulated personas against each other

https://aigrounds.tsilva.eu/ — Playgrounds for experimenting with math, AI, and ML topics. WIP; lots of slop and most are unreviewed.

https://modelviz.tsilva.eu/ — ONNX model graph visualizer

https://modelarchviz.tsilva.eu/ — View model architecture diagrams, codebase, and paper side by side. Includes a chat bot that can see selected content and select content itself. WIP.

https://embeddingviz.tsilva.eu/ — Visualize model embeddings and/or layer activations for different content with PCA, UMAP, or t-SNE. WIP and poorly tested.

https://github.com/tsilva/dlab — Workbench for deep learning experiments. Open the repo in Codex, pick a training target, e.g. maximize validation accuracy on CIFAR-10, and ask it to start a research track. Then collaborate on training runs, evaluations, sweeps, and iteration toward the goal.

Datasets / visualization

https://minariviz.tsilva.eu/ — Minari dataset visualizer: https://minari.farama.org/

https://github.com/tsilva/gymrec — Record and replay gameplay from Gymnasium environments as Hugging Face datasets. Supports stable-retro environments such as NES, SNES, Genesis, etc.

https://github.com/tsilva/youtube2datasets — Convert YouTube videos to Hugging Face datasets.

Agent / coding workflow tools

https://github.com/tsilva/runbook — Run Jupyter notebooks on Modal through a CLI, with streamed outputs.

https://github.com/tsilva/agentpong — Run coding agents in VSCode/Cursor terminals, one per Aerospace window. Agents trigger desktop notifications when done; clicking a notification sends you to the correct desktop. I haven’t used this in a while, so I’m not sure it still works.

https://github.com/tsilva/agentbox — Run agent CLIs inside Docker sandboxes. Project-level config defines sandbox access. I stopped using this once agents got better built-in approval mechanisms.

https://github.com/tsilva/agentbridge — Use an agent CLI subscription as an OpenAI-compatible API server.

https://github.com/tsilva/claudesk — Agent coordinator for Claude, built before decent agent orchestrator UIs existed. Stale and probably broken now.

Personal workflow / GTD

https://github.com/tsilva/gmail2obsidian — Flush labeled Gmail messages to Obsidian.

https://github.com/tsilva/thunkd — Quick idea-capturing mobile app built with React Native. Sends notes to Gmail, which is my main GTD inbox.

https://github.com/tsilva/capture — Quickly capture thoughts to Gmail using an Alfred shortcut, for my GTD workflow.

File / document utilities

https://dedrive.tsilva.eu/ — Client-side Google Drive duplicate finder. Lets you choose which files to keep. Poorly tested; use with caution.

https://github.com/tsilva/pdfpress — Misc PDF tools: split, merge, compress, unlock.

Made a multi-player Battlefield game for my scout group: up to 6 players set up ships like in the classic Battefield game. But you can try to hit any of the other up to 5 enemies and each team can see who hit them.

And instead of turn-based, you have to hike to/visit a physical location, fill in a code you found there to get bombs for the game. Or do a quiz and get the answers right.

Great fun so far!

You will need to place some ships (or have them auto-placed) before the game can start.

A year ago I was using claude and found it unexpectedly blowing-away already-settled code. I found this frustrating and just wanted to drop a "save point" where I could compare the before and after versions of certain files. So I built a little utility called "bup" that tarballs the whole code tree and gives it a unique name. It ignores prior backups and has options to ignore certain subdirectories, VCS directories, artifact directories, or secrets files. And you can add a single switch (-s) to create a shell script that automatically backs-up the current project. Yes I can use git for this, but this is honestly way easier, especially if I want to compare/edit different versions. No names. No files. No trees. Just "bup .". And it's 100% bash. https://github.com/maxk42/bup

I'm probably the only one who'll ever use it but I like it.

I spent days iterating with Claude Code cli tool.

Spent a lot of time initially with asking it to generate me radically different approaches. Then I cherry pick what I like, iterate over and over again.

It's still something I ask of it regularly.

Thank you for the kind words. I've always struggled with UI as I have a backend engineer background, now more on the CTO sides of things. I've always lacked the creativity IMO, and this gave me a very good opportunity to practice and try to build something ""unique"".

The funniest thing I've made is a free utility called "Moniker" that contextually renames files based on their contents.

Uses local AI models and I was able to snag this great domain name.

https://finalfinalreallyfinaluntitleddocumentv3.com/

But hands down the most useful thing I've made is HutchDB, which is a MCP service that you can call from any AI chat or Agent setup to store data for you.

Literally from your AI you just say "save that to Hutch" and then it figures out:

- The schema + fields - Builds nice webviews (Kanban, Timeline, Grid, Calendar) - Lets you share the output with people

So people use it for all kinds of things like time tracking ("every hour save a summary of my activities to Hutch"), for Agent to Human handoff ("Every day check social media for mentions of my company and save them to Hutch").

I use it for things like recording all of our marketing activities and then having my AI compare those to signups for rough attribution, etc.

Dead useful and at https://hutchdb.com

I love it! A few questions that made me think: - how do you know that "people use it for all kinds of things"? I just read your privacy policy and I'm concerned about my AI agent possibly leaking some API key to Hutch and then you can read it. - how is this free? You're hosting on Vercel, one of the most expensive hosting providers. What happens when this goes semi-viral? How do I know you won't just pull the plug to cut costs or start charging $500/month? I don't want to sign up, invest my time, and then lose access. - I signed up and now I can't access privacy policy nor terms of service pages, because when I go to https://hutchdb.com/ I get redirected to https://hutchdb.com/dashboard

michaelbuckbee3• 1 month ago

This is all very fair criticisms. This thread asked: "What are tools you have made for yourself?" and that's genuinely what this is. I wanted it so I made it and then AI makes it so easy to just throw up a marketing page.

I've a a handful of dev friends that have started to use it as well and give their feedback and it's been slowly growing as I've added sharing/invites.

I would absolutely not recommend putting big production data into it currently.

My vision for it was something more like how the #1 use of spreadsheets is actually people making lists and not actually people doing lots of calculations.

Given the uptake today (thanks everybody!) and your feedback (thanks Mystery-Machine) I'm going to work at addressing your concerns.

It's been a dream to be able to work in the audio software space. I've been a musician, designer, coder all my life, and had a few moonlights with building audio plugins over the years. But now with AI at hand, I can use it to fill that missing technical requirement while still retaining my domain expertise (music/design).

sadschnitzel• 1 month ago

I build a lot of data pipelines, and I've had to deal with too many inconsistent "source to target mapping specs" (usually Excel files) in integration and data projects in my life. They're too opaque for AI coding tools to get consistent results for generating implementations, suggesting tests, making test data etc. So I made "Satsuma" (https://equalexperts.github.io/satsuma-lang/)

At first glance, it's just a nice version-controllable, parseable DSL. But I also made succinct prompts with the grammar that lets LLMs produce and reason about Satsuma, a language server, CLI tools for the AI tools to use to navigate specs token-efficiently, reason about lineage, pretty viz in vscode plugins/syntax highlighting, some agent skills etc. There are metadata conventions for succinctly representing a lot of quirky formats and capturing common analytics conventions (scd2/Kimball/datavault/etc c.)

Yes, yes, I may have gotten carried away.

But I'm finding it really useful as a specification tool in projects for reverse engineering mappings from code/workflows, generating new code (dbt, Spark etc.)

This definitely isn't something I would've had the bandwidth to push this far before AI!

I made Circus Chief:

https://github.com/ferrislucas/Circus-Chief

Circus Chief is a tool for managing coding agent sessions from a browser. It's specifically optimized for small screens. It supports Claude Code, OpenAI Codex, and Google Gemini CLI agents.

Features

Agents can operate Circus Chief itself. Agents can spawn sessions, schedule sessions, interact with the Kanban board — anything you can do in the UI, an agent can also do.

Schedule work ahead of time.

Automatically reschedule when you hit usage limits.

Configurable, chainable prompt templates.

User-defined commands - agents can run them and see the results, and so can you in the UI. Handy for local CI or routine workflow steps.

Worktree-per-session isolation, or elect to work on a specific branch.

Shared canvas - this is a place for shared artifacts that don't belong in the code. Useful for iterating on planning documents.

Bring your own provider. Use subscription auth for Anthropic, OpenAI, or Google, or point sessions at third-party providers with Anthropic- or OpenAI-compatible endpoints.

If you want to try it:

I am still extensively dogfooding but I think I'm mostly there for my use case, probably adding some other channel support like Telegram or Discord so that it can reach out your current self host. But yeah not a prio since at least for me most of my use cases are just within my own PC (or LAN).

EDIT: Quick summary of what it is, basically you can spin up agents seamlessly and modify, supports copy paste, etc. I want it visual as well and kind of "always on", think Factorio rather than every other workflow, run on start tools.

This seems really cool actually. Just read thru the README and watched the demo gif. Any examples of what you've built with it so far? Might have to play around with it tonight.

It is dumb but very specific to my use case but an agent that runs every evening to pull both my calendar and time logs (Google sheet). The calendar I do every morning to time block my day, then throughout the day I record what I did and categorize by Eisenhower's matrix. Then it compares map vs territory and I hopefully adjust my priors to do better planning or flag time sinks.

Cool thing is I built the tools with the [Tool Builder](https://github.com/fabritorio/fabritorio/blob/main/docs/node...) as well, pretty small CLI helpers. https://imgur.com/a/XeYYbzC

I wrote a tool to give agents signal on what is and isn't clean code. I find myself spending an inordinate amount of time reviewing agent code.

After asking agents to make the same types of changes over and over again, I decided to make a tool that would just tell the agent that its code needs improving. I figured that if I could get the agent to self-review and improve the code it writes, that it would save me time when I finally come around to reviewing it.

margarita_dev2• 1 month ago

On my list of build it from scratch has always been to build a programming language. So with the help of AI I was able to get it done!

Why did I build it? At work I've seen two major problems with our ai workflows/ skills libraries. There is a lack of determinism when your whole workflow is a markdown file of 100 steps, and markdown skill libraries lack composability. Meaning we violate things like DRY in the all the md files in the skills library.

I built Margarita to allow for markdown and logical operators to exist together, which means you can bring in determinism through code structures when it makes sense, and fall back to llm dynamic code when that makes sense. As an added bonus allows for composable prompts ala React which solve my other gripe with skills libraries being a mash of text everywhere.

Overall I've been getting pretty luke warm responses from Reddit, so I'll probably just shelve it, but it was a blast to make. Got to build code agents for pretty much every llm provider and built my own harness. I would recommend doing that it's a great learning experience.

I’ve got a lukewarm IQ, would you mind explaining and example/use case for this?

margarita_dev2• 1 month ago

No worries, I'm pretty bad at describing the benefit of this project.

Let's say you wanted to use Gemma4B to run your workflow, however that model doesn't always do what you want it to. You could write the Margarita code to do the variable tracking, loops, etc and use the llm call where Gemma is able to work better. It's about finding the sweet spot of code vs llm agentic/tool calling.

Can you write that in js/go/etc? sure, but this lets you write it in a much simpler syntax that's much closer to markdown.

There's a few example on the website: https://www.margarita.run/custom-ralph.html https://www.margarita.run/components.html

Biggest win for me was building a new service to manage Cub and Boy Scout units.

Modern calendars and RSVPs via link, Roster management, LLM integration via MCP to manage all of it and send communications, and also includes a sync of all advancements and status from scouting servers (via API) so you can view them the way you want and share with parents all in one place.

Lets you customize events so you can add signups, modern document management and mapping, etc.

Also allows you to ask questions of models like “what group activity will knock out X rank for most kids” and the answers are good!

This kind of stuff is buried right now for most scout programs and units but this makes it really easy.

This will support multi-tenant so drop a note below if that sounds like something you’d be interested in.

First personal little thing was a little mobile friendly website for taking coffee and tea orders. Two pages, one for someone to enter orders, second for listing orders and marking them as done. Was a bit of a gimmick idea I'd had in the back of my head for family lunches to save me running around with a scrap of paper and a pen asking what everyone wanted. Thought it would make a good little exploration of "vibe coding".

Second is a utility that will take a text file export from Wallabag, and use text to speech to convert it to an MP3 file. I then integrated it into a utility that I already wrote for managing articles so if I tag an article with listen it automatically gets converted and gets shunted to the podcast listening app on my phone.

Last was to recreate a little directory listing utility that I've had a 32-bit binary of for ages, but no longer (if ever) have the source code for. I'd always promised myself I would write it once I learned Rust, but decided try using AI as I was getting impatient to have it now. The utility lists all files, including hidden, in a directory, grouped by type. Below is an example listing the directory for the project itself:

    Directories:
    .hg            src            target         tests

    Files:
    .hgignore      AGENTS.md      ARCHITECTURE.md               CONTRIBUTING.md
    Cargo.lock     Cargo.toml     GEMINI.md      README.md      gemini-log.html

"They just work" is a surprisingly important start. FreeCAD improved a lot with it's latest release, but it still has many flaky gaps. Caps / apices are especially hard.

Higher order continuity native to the blend would be a requirement for many, too, and the algorithms only get harder and trickier to verify correct.

Recently I got AI to help make a script to convert a CSV dump of trading activity on a trading platform for uploading into another stock trading analysis platform.

Later on, I managed to crunch the numbers in the script, and realised I could dump them out and display them in a dashboard alongside the trade activity. So I built that too,

An excel spreadsheet could have done the same job as the dashboard, but the script for conversion was greatly aided by the AI tool. The work otherwise would have been a bit of manual coding and back-and-forth testing.

ingvay73• 1 month ago

I shred guitar in the evenings to focus on technique, but a hectic day job means I get almost no time to twiddle knobs on my amp sim chasing the right tone. So I built a tool where I just prompt "Brian May Solo Bohemian Rhapsody" — the LLM fills a small JSON contract and feeds to a script that generates the XML, and I load it straight into the plugin. Two minutes and I feel like I'm tearing it up at Wembley '85 :)...almost.

The pattern generalized is LLM finds the presets,i can even upload a file to make it zone in, the code validates and loads into the plugin. Also using this contract/adapter approach for Terraform, game engine presets, CI pipelines, etc.

Wrote about it here: https://vishsubramanian.me/lm-guitar-tone-generator-polychro...

sailfast3• 1 month ago

This is really cool!

Seems like the key to the prompt it seems is the knowledge of how these tones were created in the first place (your system prompts for the 80s) which requires some actual tone knowledge and leaves all the fiddly bits to the LLM.

As someone relatively new to guitar this is intimidating, but also a fun rabbit hole. Additional “expert” prompts for different archetypes and genres could be fun.

ingvay73• 1 month ago

thanks.Frankly — the system prompt is the sauce. The LLM has encyclopedic knowledge of every amp, cab, and pedal ever made which still blows my mind, but without guardrails it'll confidently tell you to boost mids on a JCM800 (which is how you disappear in a loud mix i've noticed). That era cheat sheet is all the working knowledge over the years of spectacularly failing to get the right tones.

Once someone does that encoding work for a genre, it's reusable forever I think. I'm pretty comfortable with late-80s/early-90s rock well enough to write the specs. But you're right — a "modern metal" prompt, a shoegaze one (which my teenager wants), a funkone,etc - that's the next layer. tone_system.md just needs to be updated. I plan to expand this to more plugins. Contributions welcome.

https://docdiagram.com - A tool for creating technical diagrams. Basically an upgrade from mermaid. Load it into your MCP, prompt it, you'll get a clean diagram binary file in svg/png/etc.

https://anomalyarmor.ai/ - A tool for managing data observability and data anomalies.

Used daily by customers but also for my own work. These tools fill a gap that helps me get sh*t done.

2 tools built solo with Claude Code to scratch 2 itches. One runs on AI, the other doesnt (for now).

Any pro cycling fan will know how fragmented the live race broadcast scene is. You have to check multiple websites, some dodgy, to find the race coverage times and sources. A real PITA. Course du Jour (coursedujour.com) does that for me and tells me daily "which bike races are on TV today, and where can I legally watch them." data collecting is the whole problem: ~30 sources, 5 languages, inconsistent naming, breaking weekly, sites with factual errors, etc. So AI does the upkeep: scrapers are dumb fetchers, and Claude reads the daily "unmatched race" report and opens PRs proposing fixes.

Another thing I hate doing: copying and pasting a new contact’s information into Google Contacts one field at a time: first name, last name, company, jost, email, phone, etc. So I built ContactFile (contactfile.app): privacy-first, no AI, all in-browser, no backend . You paste a messy email signature or LinkedIn blurb, get clean contact fields, one-click file to Google Contacts or download a .vcf. Pure regex + heuristics.

I've built a handful of things, most of which mirror commercial / open source products but for which I had particular requirements that were hard to satisfy (like a wine cellar tracker where I wanted recommendations about purchases from an email list). The one that seemed most unique was a fitness / health tracking thing. There are lots of apps for logging data (like Strava), lots of coaching apps (training peaks and others), including AI coaching apps, and tools focused on recovery (whoop), but I couldn't find anything that would help me understand the drivers of my level of fitness. I run, bike, lift weights and do Pilates and wanted to understand where I got the most bang for the buck in terms of cardio and VO2 max. Turned out to be a fairly tricky proposition with a detour through understanding the limitations of measuring your heartrate with an apple watch compared to a chest strap. But I ended up getting a pretty good picture of how best to use limited fitness time in both the summer (when outdoor activities are easy) and winter (when I'm stuck inside more often due to snow, cold weather and gritty roads that making running questionable). I might open source it for other people who are as nerdy about fitness as I am...

I've built an entire app (and Swift UI companion app) to run my consulting business. It's my chief of staff that I use daily. It checks my emails, keeps an eye on client relationships, finds opportunities, helps me qualify them, etc etc.

While I am using Hermes now (and was using nano claw before), they really aren't doing much and so I'm considering folding the little functionality they do into the app, and I think it'll work better.

Part of the app is also a personal agent that checks my schedule and inserts in things into my calendar like "20 min neighborhood walk between meetings" or "break for lunch" between meetings.

I also built an entire document creation system that I use to build analytics reports or proposals, that generates very polished proposals with data about the company with me having to do very little work. All the numbers add up, the cover pages are beautifully designed and full bleed, and the documents always have perfect formatting.

No Nonsense Containers: a simple Linux containerization tool, secure by default, with support for presets.

https://github.com/brendoncarroll/nnc

I use it for running agents locally.

  nnc run /usr/bin/opencode --preset agent

You can make your own presets (which nnc looks for in ~/.config/nnc/presets) or use one from the standard library

https://github.com/brendoncarroll/nnc/tree/master/presets

Presets are written in Jsonnet, and resolve to a list of things to pass through from the parent process into the container. Presets can reference other presets, so you can build up arbitrary rules for passing files and devices into containers, give those rules a name, and reference them later.

I'm also currently working on an app that lets me hum a tune into my phone and generate guitar tabs. The audio processing is proving to be temperamental at pitch detection, but I'm planning on looking at some autotune libraries to see how they clean up audio for processing. Main problem I have is that I'll come up with a tune in my head, but by the time I sit down with a guitar and find my first target note, I've forgotten most of what I'd hummed.

The Ubuntu DDoS drove me to build a new apt-cacher with two goals: be able to supply typical packages when the upstream is unavailable and be more reliable than the existing apt-cacher/apt-cacher-ng. It's looking like I'll be doing a 1.0 release next week (it's been in beta for ~3 weeks).

https://github.com/linsomniac/apt-cacher-ultra

We do ground-up respins of half of our dev+stg cluster every morning, to test our automation, but this didn't work during the DDoS. I disabled those respins for the week of the DDoS, but if we had a fire at the office and needed to bring back up our dev+stg environment that would have been a problem: our normal ansible automation wouldn't have worked to set up a new dev+stg cluster.

apt-cacher-ultra has an "adoption" process where when it detects new repo meta-data it holds off on serving it up until it has downloaded any changed "hot" packages (packages we've fetched in the last N days), then it switches over to that new snapshot of the repo. I've been able to shut down our upstream Internet and then do a new OS install and apt update+upgrade it successfully.

The Dartmouth Summer Research Project on Artificial Intelligence was in 1956, before I was born. AI itself is even older than that (e.g. William Grey Walter's robots, Elmer and Elsie in 1948), but it was called cybernetics back then. I've been doing symbolic AI, on and off, since the 1980s.

I assume, though, you mean LLMs. I haven't used them first hand, but I have fairly recently implemented a multi-layer artificial neural network in C, mostly as a learning exercise, but as I had previously built a speech spectrogram in Lisp, I thought I'd try to use it to recognize phonemes, with one hidden layer. The Lisp communicated with the ANN via a Unix pipe. It worked reasonably well for just vowels, but when I added other sounds (e.g. l, r, s, z), its performance deteriorated. I think the C is bug free, but I don't know an easy way to train the ANN. I've tried adding to the training set, adding an extra layer, changing the number of neurons in the hidden layer. The usual debugging skills don't seem to help there.

I'm interested in how they work, but building anything like them, given the hardware I have, would be impractical. I've seen others use them, including to answer some questions I had, but the answers they gave were obvious, unhelpful, or wrong.

Even if they become more reliable, I like to understand and work things out for myself, rather than just be given the answer.

linsomniac4• 1 month ago

I've redesigned my workstation OS using NixOS and Claude Code and it's been a huge success.

I like the ideals of NixOS: reproducible setup from a git repo, ability to boot into a past config if you mess things up. But it's a big job learning and implementing that configuration manually. I've been playing with NixOS for ~2 years and like it but never really got that close to a full workstation setup.

When Ubuntu 26.04 came out I really needed to upgrade my 22.04 workstation and decided I'd really give NixOS a try before going with 26.04.

This time I decided to entirely configure it via Claude Code. I've been entirely running on it for a week and there's nothing I'm missing. I even took a stepping-stone approach where I first installed it on my old laptop, left my current workstation in place (in case the experiment failed), and then did a reinstall of my current workstation. NixOS made setting up the second machine trivial. Now, if my normal workstation were to have a hardware failure, I can just grab my /etc/nixos and rebuild and I'm back in business. Which is important since my workstation is now out of warranty and 6 years old.

One win is that I had been using LunarVim and AstroVim, and liked the "batteries included" approach, but they were hard to upgrade and while I was trying to do as little customization as possible, I still needed to do some and that was tricky in their configs. I used Claude Code to build a neovim setup with just my desired features, and it's now a single ~700 line neovim.nix file with everything in it. It's fully featured including LSPs+TreeSitter, etc.

karl_gluck• 1 month ago

I’d love to give NixOS a try on an old ThinkPad. I’m pretty comfortable with Claude; is it as simple as ask and go, or do you have any suggestions for getting started?

linsomniac4• 1 month ago

That's exactly what I did, an old ThinkPad t470s.

I installed NixOS, and then I copied /etc/nixos down to my main workstation where I had claude code working, and used it to modify the configs. I'd then rsync them to the other machine and run the "nixos-rebuild" there.

I don't recall exactly how I did the initial copies, because SSH wasn't set up there. Probably would be best to just ask claude what needs to be done to enable SSH, it's only like a 1 line change.

Some of the first things I asked it to do were:

    - Switch to flakes and tracking the latest software.
    - Switch to using Sway for window manager.
    - Various user account setup things: Configure zsh with atuin and zoxide, enable sudo, allow my SSH key for login, set up some aliases and the software I need.
    - Install claude code (I gave it the "installing" URL) once I got tired of copying back and forth.
    - Set up Home Manager and SOPS and put my secrets in SOPS, set up a variety of my scripts and symlinks.
    - Configure vim to my liking (done entirely in English prose).

Those are the top things that come to mind. Honestly, it went pretty smoothly. The only real issue I had to speak of was that I'm running bleeding edge, and the moment I decided to unplug my desktop monitors from the Ubuntu machine and connect them to NixOS I had it do a package update at the same time. This hit a Gnome+Wayland bug which left me at a black screen. A nice thing about NixOS is you can just reboot and at the grub menu select an older system config, so I did that. Claude tracked down an open bug about it, tried a few mitigations, but eventually I told it to just revert the version of gnome until it was fixed upstream.

It has gone extremely smoothly. Zero regrets. My manual attempts at NixOS always ran me into dark corners that I didn't know how to do (like installing gitbutler-cli, which is not packaged for NixOS yet), and Claude had no trouble figuring out.

I have a service that runs on my home server and uses the Ubiquiti API to detect when I'm on a zoom call. It then pauses my Sonos network-wide. Unpauses when the call is over. The next step of it is to have it's own podcast library, so I can have my own little talk radio going on in the background all day.

Some point, I want to convert into a little app and open source it, so you can install on your laptop so it's usable by more people. And have it detect more than just zoom.

this thread is crazy.. hackers are clearly hacking, myself included. A lot of what I've built I've already seen here:

1. home automation, access point management, solar/battery health monitors

2. family week management with schedules, todo's, scripture of the week

3. page-to-pod (browse, click one button, TTS to podcast episode on my phone)

4. daily summary of AI news to a new pod episode on my phone

5. easy theme switching from light to dark on my mac

6. and more....

what does this mean about the future of software? looks like consumer software will be "instant and on demand".

linkjuice4all• 1 month ago

These are all very neat things and I’m very pleased to see the hacker spirit move into AI, but I gotta admit - some of this just comes across as “what did you print with your printer?”

Another recent thread mentioned that AI has helped devs build better “shop jigs.” This seems to be where the rubber is meeting the road for AI-powered development. So maybe more people will be developing custom tooling for their own little problems but you still need reliable, deterministic, interchangeable tools to realize the value of all these shop jigs.

I rely heavily on DeepL Write for my day job, but I dislike the constant logouts, nagging, and laggy UI. I coded a DeepL Write replacement that uses the same layout (two text windows side by side, with the left window for entry and the right window showing suggested edits as an actionable diff), but all suggestions are based on Harper + Gemma.

When I want the program to reformulate a sentence or phrase, it sends the sentence to an AI that provides word or phrase suggestions. I've connected this to Tinfoil.sh (not affiliated) via API key.

Now, I have a much more private DeepL Write replacement with a snappy, consistent user experience that costs much less. Unfortunately, the suggestions are not as high quality. It's very much an 80% solution. It was still fun!

Most of the rest concerns scraping. The biggest project is an extraction tool for the German transparency register that I need for work.

I built an iOS app for my sons who play club basketball. It’s designed to bridge the gap between practicing solo on the court and the pressure of playing in a game.

It uses mechanics and body movement, via visual detection through the cameras, to identify when you’re about to take a shot or make a pass.

It then pumps distracting noises (honks, cheers, jeers, etc.) into the headphones to try to distract you. It also runs a continuous 24-second clock so you build a natural sense of how much time is left before you need to get a shot off.

https://github.com/amedeedaboville/mish A mosh clone that uses QUIC as the transport layer so it can do both “unreliable datagrams” like UDP and also a TCP-like reliable stream, so it has scrollback buffer.

Also QUIC means the crypto is handled for me, no need to trust the LLM to hand roll its own crypto.

Cool Rust libraries enable this like alacritty for the terminal, and being able to have russh (rust implementation of ssh) means it works even if ssh isn’t installed (eg on windows which og mosh never supported).

Claude tested this thing forwards and backwards: e2e tests, simulated (foundationDB like) tests for the network and for tokio async thread ordering, 12 different fuzzing targets, even some light model checking on the protocol itself. Each fuzzing round found bugs.

Except for a few “it may have bugs, I have only proven it correct” scenarios I’d say it’s looking like it’ll be as trustworthy as (maybe more than?) the original. I’m really happy with it.

— daily notes, goals, client info, business info, ideas, and facts

- Search your vaults for context when you ask questions

- Help with journal prompts and reflections in your daily notes (I ask context dependent questions randomly throughout the day that are based on your notes)

- Create new files when you need them

- Answer questions about your life, businesses, gear, plans, etc.

- Reminders (i.e. "/remindme in 2 days to [action]" and it will text me at that time)

Total game changer and I never would have built it without LLMs.

I've made a general repo linting tool [0][1]. Originally it's purpose was to replace a bunch of repo hygiene/structure validation scripts I ended up adding as I noticed various sloppy AI changes. I ended up going through a bunch of open source repos to see what other kinds of validations they had via scripts and incorporated those into the tool as a set of general/extensible rule types. This tool allows you to define repo structure, hygiene and other rules in a declarative way, and it is very fast [2] (great for pre-commit and CI workflows).

I've continued working on a tool for my daughter, our friends, and I to scan and index Pokemon cards. The tool is a phone app and website (https://MyBulkCards.com) The phone app uses the camera to scan a card and run the image through a couple of models, a record is written of the card along with the location. It's pretty basic, but I can store cards in boxes like “Box 1 AAA, Box 1 BBB, …” and find cards easy peasy. There’s also a friends feature so I can see what others have locally. We borrow cards from each other quite a bit.

It's been a super fun tool to build. The phone app just got approved in the Android app store. I have a bit of cleanup, but plan on releasing it soon.

Workhorse is a CLI set of scripts / tools that turns an old laptop into a headless SSH compute/storage node that my main machine offloads to.

Main components are: - a router script (onpro) that probes the box and runs the command there, falling back to local automatically if it's asleep or unplugged. - a PreToolUse hook in my AI coding setup intercepts the heavy commands like builds, test suites, ffmpeg, OCR, big pandas jobs. Forces them onto the workhorse instead of melting my MacBook Air.

The agent decides what to run, and a deterministic layer guarantees the heavy stuff lands on the right machine.

Testing Workhorse a bit more before sharing.

Also https://motate.app/ was an attempt to make math writing easier for me (as I recently needed to hold my newborn through most of my LinAlg refresher course) but I've since started trying to figure out how to make it useful for broader science/math writing and education.

As in "symbolic link" vs "hard link" - where hash tying host repo and pseudo-submodule is not git-generated, which makes "submodule" completely substitutable. For the description of creation process see the relevant section of Readme.md

- Companion script named Dr.Emmett - to retrospectively time-walk git commit history and rebuild the repo in a new place. It is not opened yet, and may not be ever as it doesn't satisfy LLM/human ratio worthy of publishing.

- Both scripts were made in service to my FNA-"game" project VibeSopwith: https://github.com/fontmaniac/VibeSopwith.Game. A more or less comprehensive description, and treatise on my stance about vibe- and agentic-coding can be found in the project's Readme.md

- VibeSopwith catalysed creation (accretion?) of Nage.Strata: https://github.com/fontmaniac/Nage.Strata - "Not-a-game-engine" collection of useful "primitives" for FNA-based game development.

- VibeSopwith Readme.md has notable mention of "Aether Bodybuilder" - a helper tool for visually coupling Aether.Physics2D "bodies" to specific sprite textures. Fully vibe-coded in a couple of hours, and as such won't ever be publicly opened, having LLM/human ration approaching infinity.

Since the advent of AI, I've built a voice memo app for myself. I can go on an hour-long walk, talk stream-of-consciousness style, and then have Claude structure my thoughts into organized notes. It's a great way to process ideas just by thinking out loud.

I have a telegram bot, and I used to have it read message in a group chat to detect the language, and if it wasn't English, it would use gpt5 nano to translate.

To save on inference, I had Claude create a lightweight typescript library to handle translations and detection. Now I get the previous functionality for 200mb~ ram versus paid API credits.

I also built a home assistant menu bar in osx, let's me easily monitor activity, toggle devices, view cameras, etc.

I’m currently building and testing a new architectural framework where business logic runs on the client side.

The core idea is to run TypeScript inside a WASM VM, while minimizing the exposed JavaScript APIs. Backend business logic is encrypted and executed inside WASM, making the attack surface much smaller.

Security is the biggest concern, so this framework is designed to apply as many security layers as possible and dramatically increase the amount of time and effort required to hack it.

It includes E2E encryption by default, tenant policies, an SQL registry, and many other security policies. The framework only becomes truly safe when these policies are properly applied, but the major advantage is that it can be operated at almost zero cost.

Another key benefit is that both the frontend and backend can be deployed together, and when used with Cloudflare, one-click rollback is possible.

The biggest advantage is that you no longer need to worry about infrastructure. It allows MVP projects to be built, deployed, and operated as quickly as possible, with almost no operational cost.

The project is called *dokkebi-cli*.

I made a custom golf simulator app. There's a Swift app that talks to my Garmin R10 launch monitor via Bluetooth low energy. When it records a shot, it grabs the data and throws it over to a web app running locally on my laptop, with an SVG simulated shot arc, an attached video of the shot captured from my phone (or my laptop's webcam if I'm lazy), and all of the metrics that came across. I keep all of my sessions with shot data and a little overlay of where each shot went (and which club hit it).

The reason I wanted this is because all of the existing golf simulator software I've looked into is either too expensive, requires too much computing power (E6 requires at least an RTX 3060), or both. And most of their selling points seem to be visual fidelity of playing against real courses. As I'm just looking to improve my game, that's not something I need, and Sonnet 4.6 was able to get me to a great spot (and I'm trialling some new additions like slow motion video capture and pose tracking via Apple's Vision framework using Fable 5 right now).

https://github.com/haplo/pelican-theme-reflex — My Pelican [1] theme. While I started it before LLMs were a thing, I was recently able to tackle all my open TODO items with AI.

https://github.com/haplo/pelican-copy-code — A Pelican [1] plugin to add a Copy button to all source code blocks. It happens at build time, so no DOM manipulation at page load time.

https://github.com/haplo/venice-kde-widget — A KDE Plasma widget to display Venice.ai [2] remaining

I'm currently writing a series of blog posts about these that I call Vibe-coding Escapades [3]. I will also write about bugs and technical problems that AI helps me debug and solve, some are non-trivial and have been pestering me for years.

I have built several tools from general purpose agents to the current project I am working on which is AgentLine - Telephony services for AI agents it gives a phone number to every AI agent to call and sms. I built it over a period of 14 days now I have refined it so much that I have more than 36 paid customers with 300$ in Monthly recurring revenue.

Made "stop localhost" publishing for vibe coders called Revdoku. It is useful when need to quickly publish a prototype, report, set of documents and can be done right from Claude or Codex.

If you use ChatGPT then can say it is more like ChatGPT Sites but also works in Claude.

I used notebook LM and claude/gemini to gather the notes on K8s and created a vitepress site with it.

Claude/gemini helped with design and content meta. NLM for content with official sources.

https://randomwrites.com

I am doing a similar with linux internals (to be published soon). ofcourse from the official docs and asking some questions around the concepts i like and forget mostly :-)

usrme• 1 month ago

I'm right in the target audience for this as I'm about to embark on a Kubernetes certificate. What is the proportion of official K8S documentation and your own notes and how could someone differentiate between them on that site?

mutahirs2• 1 month ago

i used the official k8s docs and fed them as sources to NLM. Then asked questions around topics. further refined some questions as well to make them useful.

its only generated against official k8s docs so no external sources. thanks

Photo Organizer - Organizes image and video files first by original directory name, then by EXIF date, if any. Renames images to img-yyyymmdd-hhmmss format and moves them to yyyymmdd directories. I've planned such for a decade, but I was too lazy to spend a week or two with it (I mean some evenings, ca. a week). Vibecoded in ca. two days: https://github.com/ern0/photo-organizer

Timelapse-consolidator: create a single timelapse video from multiple captures, ignoring night shots. I think, it's a good example for splitting the task for separate programs, which task size the AI still can handle. See prompt for details: https://github.com/ern0/timelapse-consolidator

(Night shot detector should be faster, instead Python, I would rewrite it in some native language, like Rust, but it will run once per project, so it's not vital.)

Sony-TV-Control: the battery in the RC is started to discharge, so I've downloaded Android apps, which can control our Sony smart TV. Tried some, but I was disappointed, so asked DeepSeek if Sony TVs have some API. Instead of demonstrating the API, DeepSeek created me a simple RC PoC, which looked promising, so I decided to continue vibe-coding my version, a mobile-first webapp with Python backend: https://github.com/ern0/sony-tv-control

It has several functions which a normal RC can't have, e.g. search channel by name, or hide "ABCD" channel, if it has "ABCD HD" pair, to make channel list shorter.

The first thing I did was set up Linux's inbuilt imap-filter service to handle push notifications from Gmail:

https://github.com/yo-chanan/gmail-imapfilter

I had looked everywhere for a simple system service that supports Gmail, or a chrome extension that supports push, and was able to find neither. Then when I started using Codex, I thought "Here, go automate the setup of the imap-filter service for Gmail."

An Android mobile app that sends e-mails to myself. So far private, but I use extensively throughout the day to send notes to myself.

If someone wants an invite drop me an e-mail.

If the answers in this thread reflects the state of the art what "the advent of AI" as of 2026/6 has brought, I have to say that I am not amused. If we have this all-potential tool that can create anything, the potential is clearly capped by either people's ambition/imagination or the capabilities of coding agents... And please do not understand me wrong, I am just stating that I feel/think that the real-world examples of achievements should be something "next-level" stuff...

amrangaye• 1 month ago

So many things - reminds me of the days when you'd throw together a quick shell or Perl script to solve a very particular itch. So I have a whole collection of apps, portals, demos, etc.

Which is what leads to my issue: cognitive overload, and very high context switching costs especially as I'm usually on multiple work and "hobby" projects at a time, with multiple projects spread across term tabs, IDEs and Claude remote on phone.

So I built a "Workshop" to tinker. It analyses all the projects I'm working on currently as git repos on disk, then builds project pages complete with summary and a full control and data planes including its own startup method, commits being made etc. It does some agent introspection so it's able to display all agents running on machine in unified view.

But the "killer" feature for me is the "Pulse" - this contains human readable summary of what's happening with each project and agent in real time. So one use case is an "overnight view" - I set up architecture and design, assign the agent a goal, then wake up next morning to quickly scroll through the results. It also lets you track changes happening in real time ("We finished adding an export function for receipts, containing your company logo and signature" to summarize a feature across 10 commits).

I also added other useful to me utils such as being able to append a ? To any command in its inbuilt terminal and it'll convert it from English to a cli command waiting for you to confirm, for example; a system load monitor; a network sniffer, sys admin tools etc. all written in Rust, which I've never written a line of :)

Will put it online but need to clean it up first it's very specific to my use cases so not sure it'll be useful to others.

I've effectively automated about 70% of the data gathering and insight generation I need as a procurement and supply chain consultant.

I built a tool to manage survey collection and analysis of the underlying data. In the process of doing so, I stumbled across GraphRAG and Answer Set Programming. Fair to say I fell down a rabbit hole and things grew a bit...

- Category strategy and market analysis - Supplier risk monitoring - Emissions reporting - Modern slavery risk analysis & reporting

I also had Claude Code build me frogger so I can properly procrastinate.

Built a wifi checker for my Piaware remote servers. Checks if the internet and router connection are present. If router connection is up but internet is down it’ll restart the network but if nothing works for like an hour after a few checks it reboots the whole pc. Way better than my chrono if ping else reboot loop lol

Ask HN: What are tools you have made for yourself since the advent of AI?
