Got recommendations for specific songs / groups for Lo-Fi beats & jazz? What I've found is that many lo-fi playlists contain songs that have a lot of distracting noises (voices, distorted guitar twang, rain drops, record crackle, etc) - so I've been slowly-but-surely making playlists of study/reading songs.

Thanks!

What has worked for me is (1) Buy 4+ boxes of coconut water (2) remove cannabis from your house, (3) drink coconut water whenever you feel like smoking, (4) get some exercise going (swim, push-ups, gym, sports) - whatever the "MVP" of exercise is to start thinking of your body as fit, athletic & strong.

Here's a list of Pivotal Tracker-inspired tools. https://bye-tracker.net/

Some potentials:

- Lanes: https://lanes.pm/

- Brooklyn Tracker: https://www.brooklyntracker.com/

- Tracker Boot: https://trackerboot.com/

- Story Time: https://storytime.team/

I would love to see an open-source one exist, potentially using open formats like Markdown / SQLite which could run locally or on a network share, and could potentially "live" inside of the repository.

I'm currently in LATAM, and often teach students - so having a no-cost tool which supports agile development would be so valuable (rather than having yet another tool to create a login for)

You can read about China's modern carrier-based, stealth fighter here: https://en.wikipedia.org/wiki/Shenyang_J-35

There is a section about its engines: https://en.wikipedia.org/wiki/Shenyang_J-35#Engines

The first engine they used for the J-35 was the RD-33 (designed/built in Russia): https://en.wikipedia.org/wiki/Klimov_RD-33#RD-93 - It was not efficient enough for the J-35 and generated black smoke trails. China decided to design & build a China-based engine.

This is the engine for the early J-35 prototype, WS-13 built in China: https://en.wikipedia.org/wiki/Guizhou_WS-13

This is the production engine for J-35, the WS-19: https://en.wikipedia.org/wiki/Guizhou_WS-19

China has built 50+ J-35 aircraft, and is scaling up production to support their domestic military, and also export orders to other militaries (including Pakistan, and possibly Russia).

Interesting: This is China's latest aircraft carrier, which has electromagnetic catapults, instead of steam-based: https://en.wikipedia.org/wiki/Chinese_aircraft_carrier_Fujia...

You can see videos of the J-35 aircraft here: https://www.youtube.com/watch?v=oLdCNAUjuRI

Good questions. For some "work" use-cases, it would be starting up Email, password tool (Bitwarden), team chat (Slack), browser (with a few tabs already open).

I am trying to get into a habit of writing/publishing, so I've got my own web-page that pops up at login, along with the code/text editor that allows me to start writing. Every individual will have their own set of "things I click on / open while sipping coffee, getting the computer into a productive state".

In the team / consulting environment (where we would pair-program, often with different people day-to-day), the computer would start with task tracker / backlog (at the time, Pivotal Tracker, now it would be something like Linear), team knowledge base for the project area. Under the hood, it would load up common shortcuts, terminal aliases, etc.

----

I often work with multiple clients, so something I've always wanted to do is have something close to "one Linux user per client", so that there isn't "contamination" between them. I haven't figured a great way to do this, but think of it a system-wide version of Chrome's switchable profiles.

No Systemd 22 days ago

I'm curious - has anyone found / created easy-to-use Systemd GUI interface?

A bit of context: My specific case is creating timers (similar to crontab). I'm shuffle-playing music playlists at certain times of day. I'm comfortable with terminal/command-line, however the computers I'm building out are used in maker-spaces, where many people are not super technical. This has got me into the habit of thinking "what's the 'easy mode' for a lot of tools. For example, GitHub Desktop is a great way to slow-roll people into using `git` if they have never used it before. I like tools like that. Let me know what you suggest.

I have a cron job which restarts my computer every day (Linux Mint Debian edition). I like waking up to a "fresh" computer, and since I know that it will restart every day - this is a "forcing function" to (1) be diligent about saving things that are important, (2) treating browser tabs, random notes, etc as ephemeral, and bookmarking the important stuff.

I used to work at an office where we pair-programmed with clients all day (Pivotal Labs), and most of our computers had some sort of "automatically restart / restore from a known-good image". I liked this, as it resulted in less cruft over time, and some intentionality about what getting a computer into a productive state means. It also got me thinking of using automatic routines to accomplish goals, and not being so attached to my open tabs, etc. Let it gooo....

To be more specific about this - for those wanting to get into blogging/publishing, this could mean auto-opening the website project folder using VSCodium upon user login, so its ready to go for the morning coffee. More half the time I just close it - but as a "default", it makes it easy for me to do the thing I want to do.

  sudo crontab -e -u root

Does anyone know where you can buy an HDMI-compatible e-ink display, which is about the size of an A5 notebook? The idea is that you could have a screen, keyboard, and a small computer zippered up in a case, and could write/code outside in the sun.

Hey everyone! Earlier today I asked HN to share their AI-driven software development workflow & tools. This is the discussion, worth reading & contributing:

https://news.ycombinator.com/item?id=48413629

In the spirit of summarizing the knowledge shared, I took notes on all of the comments, and "stack ranked" the tools mentioned (simply be frequency of occurrence in the comments). The reason I did this was to give me an idea on which tools to start exploring.

I have shared these notes here: https://codeberg.org/jro/Knowledge/src/branch/main/2026-06-0...

I am on a learning path, with the intention to run in-person workshops for people looking to "boot-up" their development workflow, feedback and improvements to this document are encouraged and welcomed. Let's learn together.

Feel free to add commentary, improvements, ideas in this thread. Thanks!

I find the best way to learn something is teach it. My philosophy with workshops & teaching is that we are all learners/students, on different parts of the paths (versus the idea that one person / the leader is the absolute authority). So the idea is to to create a learning environment (a time, place, and people), and help each other out.

A lot of us are doing this stuff solo anyway, and doing it socially is more fun and usually more effective (easily get unblocked).

My dream device is the "Solar A5 e-ink computer" - It's A5-sized laptop, so it fits in a leather zipped case for journals. If you're familiar with HP Journadas / Sony Vaios from early 2000s, that's roughly the form factor. There's a solar panel on the back of the screen / outside of the enclosure. The screen is e-ink, and the operating system is Linux Mint Debian Edition. For console mode, a good "writing station" applications are "mc" (Midnight Commander) and "ranger" - simple GUI for editing text in folders, like a blog/knowledge base.

Some challenges I've experienced: (1) Can't find A5-sized e-ink screens that accept HDMI as an input, (2) It would be cool to use a common Android phone, since there are many around. RaspberryPI is an option. Honestly, would love the simplest portable device that runs Debian Stable on a battery, (3) I have NOT been able to find small, A5-sized keyboards. Most small keyboards are cheap plastic bluetooth junk.

If anyone would like to seriously rally around this, let's talk'bout it. My vision for this laptop has always been "10:00 AM Austin Texas, sitting at a patio bar in direct sun, journalling/coding/writing". I have not been able to find any computer device that satisfies that situation, so there is obviously a market niche.

Worth mentioning - for a long time, I found my handwriting messy AND my hand would tire out. When I was about a teen-ager, I decided to write in call-caps, very clearly. I've been doing that for a long time now, and worth giving a try.

I read a book about this called Life After Life, written in the 1970s. A doctor spoke with hundreds of people who experienced Near Death Experiences, and wrote commonalities / patterns that most experienced. Found this absolutely fascinating. Coming from a non-religious background, I found this book somewhat of a brain breaker.

As others mentioned (including @BoardsOfCanada) - search for "NDE" on a video platform, and watch a few. I make no claims to be a professional assessor of truth/lies, but when you watch many of those videos, ask yourself honestly, is this person lying (or rehearsing a staged story)? Additionally, some mention "impossible" information (like an out-of-body experience, where they are able see something outside of the room, which would be impossible for their body to do; or receive/hear information).

What I appreciate about that book is that the doctor (Raymond Moody) doesn't offer judgements or much of his own opinions, but he tries to faithfully retell what the patient experienced.

What's interesting is some of the discussions the patients have with the "luminous being(s)" and souls/spirits/entities on the other side...

They seem to frequently ask questions like, "What did you learn (while on Earth)?" - and there is the implication that our souls are sent to Earth with a specific mission.

The people who experience these NDEs also often say that this other world (spirit/soul world?) feels MORE REAL than the Earth world, and that they report feeling finally "at home".

Other interesting observations - (1) they rarely smell anything in the other world, (2) many report perfect sight / knowledge (for example, can clearly see infinite detail of a mountain range on the horizon), (3) Often hear musical "chimes", (4) the "luminous beings" have a sense of humor, and are not judgemental during the life-review, (5) During the life review, they often get to see the experience from another perspective - for example, during a fight with a sibling, you can see the fight/feelings from the other siblings' perspective, (6) the people often come back with some sort of "gift" / power - for example, the ability to sense other peoples' emotions at a distance (like extreme empathy), or to heal people with touch. (7) Apparently suicide is a big no-no - the people who attempted to kill themselves were essentially "scolded", told that it was a huge mistake - "We" are not supposed to decide who dies, including ourselves - and that we have a mission to carry out, even if the circumstances are difficult. That was a bit shocking to read...

Pretty fascinating stuff.

I personally have not experienced an NDE, but I have spoken to several trusted friends - including a man who drowned as a child, and was brought back to life. He experienced the common "symptoms" of the NDE described in those videos... just the level of detail he can recall from the conversation he had with the "luminous being", and the extreme feeling of "home" and intense love he experienced - he said that since that point, he's not afraid of death at all, and after that experience, he felt strongly driven to become a teacher and help others....

Worth checking out, even if just for curiosity / open the mind's sake...

One option to check out is VSCodium + FOAM plugin. When editing a folder of Markdown files, you can cross-link to them using Obsidian-style links.

Later, if you want to publish the files as HTML, you can use MkDocs.
