Rust originally came with a green thread library as part of its primary concurrency story but it was removed pre-1.0 because it imposed unacceptable constraints on code that didn’t use it (it’s very much not a zero cost abstraction).

As an Elixir + Erlang developer I agree it’s a great programming model for many applications, it just wasn’t right for the Rust stdlib.

Cmon, this is the guy that was running a shady online casino which was tanking Cloudflare’s IP reputation, completely different.

This is in part because those countries have been historically reliant on the US for their national defense…

Huh, interesting. Looks like they were indeed quite different until the Mk3 in 2012

It has found actual reproducible SQL injections for me as well as XXE vulns.

Sonarqube did not flag public fields as a security issue by default the last time I used it — however it has found several real vulnerabilities for me before.

New comment by jolux in "Ask HN: Are you using an agent orchestrator to write code?"

jolux — Fri, 13 Feb 2026 05:15:31 +0000

No point. Claude Code with skills and subagents is plenty. If they would stop breaking it constantly it would be fine.

The bottleneck has not been how quickly you can generate reasonable code for a good while now. It’s how quickly you can integrate and deploy it and how much operational toil it causes. On any team > 1, that’s going to rely on getting a lot of people to work together effectively too, and it turns out that’s a completely different problem with different solutions.

I think they just posted the link they log into. The site is ui.com or store.ui.com.

Checked exceptions are bad because people just catch them and rethrow RuntimeException. Proper errors as data would be much preferable.

I couldn’t quite tell from your comment. Anyway it’s not my experience with CC but everyone seems to have a slightly different take on it.

It's not just for security, it's also for maintainability. Frankly being able to reflect across package boundaries has always seemed like a misfeature for maintainability to me. The code you have that is broken by Java 9 was already badly behaved, the JVM was just lenient about it.

Ah, it was written in Groovy last time I looked at it I believe. In any case here’s how to install a default java:

`mise ls-remote java` to show all vendors and versions, or just `mise latest java@temurin` (or any other vendor) to get the latest version string

`mise use -g java@` to install it and set it as a default

pro tip: don't bother with SDKMAN. use https://mise.jdx.dev to install Java, it can also install a bunch of other languages and tools. it's most likely the last tool version manager you'll ever need.

New comment by jolux in "Chezmoi introduces ban on LLM-generated contributions"

jolux — Wed, 22 Oct 2025 15:58:49 +0000

I’m aware of the context, but as someone who frequently uses LLMs productively I find bans on all usage to be misguided. If in practice the rule is “if we can tell it’s AI generated, we’ll ban you” then why not just say that?

Moreover, in the case of high-quality contributions made with the assistance of LLMs, I’d rather know which model was used and what the prompt was.

Nonetheless I still understand and respect rejecting these tools, as I said in my first comment.

chezmoi is a great tool, and I admire this project taking a strong stand. However I can’t help but feel that policies like this are essentially unenforceable as stated: there’s no way to prove an LLM wasn’t used to generate code. In many cases it may be obvious, but not all.

> I've heard this argument, but it also doesn't pass the sniff test in 2025.

I mean, it's at least partially true. I used to play BioShock Infinite on my MacBook in high school, there was a full port. Unfortunately it's 32 bit and doesn't run anymore and there hasn't been a remaster yet.
