Check out https://github.com/anthropic-experimental/sandbox-runtime, which tackles this problem using the built-in userspace sandboxing on macOS and Linux.

I run Claude from a mounted volume (but no reason you couldn't make a user for it instead) since the Deny(~) makes it impossible to run from the normal locations.

export CLAUDE_CONFIG_DIR=/Volumes/Claude/.claude

Minimal .claude/settings.local.json:

    {
      "permissions": {
        "allow": [
          "Read(/)",

Eleos Technologies | DNS Consulting | REMOTE (US) | Contractor

We build mobile apps and supporting systems for long-haul truck drivers.

We have a critical DNS registrar/hosting migration to do this year and while I did the last one (on a less-critical domain), I'd really like support from someone who has done >5 of these to help our team get it right. Good news: no DNSSEC. =)

Please reach out to me at phil@eleostech.com and mention this post if this is you and you have a reference or two. It should be really easy project for the right person, but we'll compensate commensurate with the business risk.

With two[1] other[2] great articles about the guts of how programs _actually_ get loaded and run, I was reminded of the above great (multi-part) article, which I remember reading on the subway in tiny chunks and being surprised it ever works at all.

My CS degree was from a liberal arts university, and while I wouldn't trade anything for the coverage of ethics, previous AI bubbles/winters, and my time in the business and mathematics departments, these articles along with the glibc author's What Every Programmer Should Know About Memory[4] rounded out my education. I still make use of concepts from both when profiling and debugging programs.

I hadn't yet seen it when I wrote this, but 2 is pretty much exactly what Arko says:

Worried about the possibility of hacked accounts or some sort of social engineering, I took action as the primary on-call engineer to lock down the AWS account and prevent any actions by possible attackers.

https://andre.arko.net/2025/10/09/the-rubygems-security-inci...

Putting myself in Arko’s shoes, I can imagine (charitably!) the following choice, realizing that I still have access and shouldn’t:

1. Try to get in touch, quickly, with someone with the power to fix it and explain what needs to be rotated.

2. Absent 1, especially if it cannot be done quickly, rotate the credentials personally to get them back to a controlled state (by someone who actually understands the security implications) with the intent to hand them off. Especially if you still _think_ of yourself as responsible for the infrastructure, this is a no-brainer compared to letting anyone else who might be in the same “should have lost access but didn’t, due to negligence” maintain access.

Not a legal defense, but let’s not be too hasty to judge.

I would only partially agree that Kotlin is "much safer."

As one example, I just learned (by way of a nasty production app crash) that Kotlin chose to make all checked exceptions silently unchecked. Kind of a stunning own-goal for a language from 2010.

Eleos Technologies (https://eleostech.com) | Remote Front-End Web Engineer | Permanently Remote (US-based applicants only) | Full time

Eleos Technologies is a growing company building communication software for truck drivers and the back-office workers who support them. We’re looking to scale up a second product engineering team to ship more advanced driver planning tools, automate outdated workflow, and a bunch of other wins to make drivers’ lives easier and more efficient.

We're looking for someone with several years of professional web experience who's looking to learn and flourish at a company that's big enough to survive an economic downturn, but not so big you can't make immediate, direct impact that'll be seen and appreciated by the whole company. (We've also spent the last decade working really hard to make sure our tools, processes, and culture respect everyone's work/life balance. I'm the CTO and I don't text people on my team, and they don't text me, and that's true throughout.)

The stack is Erlang/Elixir with a ClojureScript+React frontend with robust automated test coverage.

If you're interested, please share your info via https://jobs.lever.co/eleostech/629c95b5-2205-4d5e-af25-4ca5... or feel free to reach out to me directly if you have questions (email is in my about/bio).

We're looking for someone with several years of professional Android experience who's looking to learn and grow on a team with multiple members with 10+ years experience on mobile in a company that's big enough to survive an economic downturn, but not so big you can't make immediate, direct impact that'll be seen and appreciated by the whole company.

Oh wow, thank you!

I'd been poking through them with plain old `sqlite3` and then deserializing all the plist data with something like `pbpaste | xxd -r -p > foo.plist` for examination, but had no idea datasette existed and https://datasette.io/plugins/datasette-bplist#user-content-t... seems like the ticket for browsing these.

For others: all the Caches.db files are the per-process HTTP cache that NSURLRequest/NSURLSession keeps, so if you peek at it you can see (partially) a history of network requests that process has made. Most of them seem to pull feature flag configuration from https://bag.itunes.apple.com/bag.xml, but others do more interesting things.

We've got a similar role open for iOS, too, if that's more your speed: https://jobs.lever.co/eleostech/62b47296-9e81-4b1e-be52-3db1...

Email George Blood LP (https://www.georgeblood.com/), they have support to read like 100+ old magnetic formats and are wonderful pros.

Separate teams. We have a tiny team and even _we_ appoint a group to fix and a group or individual to do nothing but communicate.

This. We have a 4-person team and posted our own incident about this 7 minutes before Amazon did. Surely they can aim a little higher.

Based on our telemetry, this started as NXDOMAINs for sqs.us-east-1.amazonaws.com beginning in modest volumes at 20:43 UTC and becoming a total outage at 20:48 UTC. Naturally, it was completely resolved by 20:57, 5 minutes before anything was posted in the "Personal Health Dashboard" in the AWS console.

It takes a while to find a Vice President, I guess.

Our app is used by thousands of big-rig and small truck drivers, day and night, every day, and we've been on a sustainable growth curve for long enough that we're ready to grow our backend team!

Our driver-facing mobile app does some unique things, including assisting drivers with planning their trips, finding stopovers, managing their electronic duty log, and more. These features are (with a couple of specific and thoughtful exceptions) natively implemented, and we take the performance and stability of the app seriously.

We use a homegrown gnuplot version of this at $work, and I can speak from experience that you can immediately spot problems (timeouts, as a set of ghostly horizontal lines, or outlier requests) that would be absolutely hidden in a traditional p50/p95/p99 chart.

I wish more (hosted) monitoring systems would shift to this type of visualization, since computers are fast now (I'm told!)

Makes sense—haven't seen the show but appreciate the context.

That said, for placeholder text as much as for jokes, "if you have to explain it…"

Nicely polished landing page and a very cool idea.

A few clicks into the demo, though, I came across this example copy in one of the pre-built components.

This is such a great product that I feel aroused every time I use it. I didn't know the boys would be able to build, but god damn it, they did it. Kickass!

Maybe consider lorem ipsum or similar text if you don't have a designer who can write placeholder copy. This is, frankly, just gross.

This gives me some hope.

I once made vegan tiramisu for a friend using aquafaba made from boiled dry chickpeas, and the sweet/chickpea flavor tasted exactly like the worst kind of vomit-burp imaginable. It is one of probably 2 or 3 of several thousand meals I've ever cooked that I threw directly into the bin after having another person confirm the flavor.

This! A printout of the Paredit reference card [1] taped near my monitor is the only way I was able to learn it.

[1] http://pub.gajendra.net/src/paredit-refcard.pdf

This is something I'm very curious about! There's a strong meme that SQL is dynamically typed, but it is very much static. ("Compile time" is "prepare time", so it feels dynamic compared to host program compilation, but the vast majority of problems are caught before query execution, and with widespread, better tooling, could be caught at host program compile time too.)

Do you call it dynamic because of the delay in getting error feedback, because the RDBMS you use is genuinely loosey-goosey with types, or for another reason?
