I can't figure out why this font is better than DejaVu Mono, or Monaco (mac). They all look basically the same to me. I actually would love someone to explain what the difference/improvement is, in other parts of life I know subtle changes add up.

Yes. That's why you should use Doom Emacs.

New comment by rhaps0dy in "Think twice before translating all C to Rust"

Possible! But fixing this seems easier than re-writing in Rust with reasonable expectation that the software behaves the same?

New comment by rhaps0dy in "Is memory-safe Linux within reach?"

Most Linux CVEs are memory corruption bugs. Previously I argued that we should compile C to be memory-safe rather than translating all C to Rust, to avoid introducing logic bugs.

Here, I argue that several parts of the kernel can also be compiled in a memory-safe way.

Is memory-safe Linux within reach?

Unless we go extinct. But I concur.

I'm vegan, I don't eat tortured animals. Thanks though.

Yeah, that's fair. There's hope though!

rhaps0dy — Sat, 15 Nov 2025 00:00:55 +0000

Yeah, but long term it will increase GDP due to the UK being able to have better (fewer) regulations than those allowed by the EU. It does require Parliament getting it together.

New comment by rhaps0dy in "Helm 4.0"

rhaps0dy — Thu, 13 Nov 2025 15:18:10 +0000

To solve all the problems with Helm it seems easy enough to use Python dataclasses that serialize to YAML (or your favourite language).

Then to convert a new Helm chart to this you can just use AI + tests that check the two things render to the same output.

This is awesome. Measurement and experiment for a very quotidian thing is a great vibe.

Yeah, it's very clearly LLM-edited, but it's fun to read. The LLM did a good job.

It's not just a tech blog post - it's a thriller. ;)

Basically Emacs Lisp. Where `nil` is the only falsy value, and anything else (including `t`, which analogizes to `Some(())`) are truthy values.

> First, like others mentioned, you'll have N+1 problems for nested lists. That is, if we call comments() on each post and author() on each comment, we absolutely don't want to have one individual call per nested object. In GraphQL, with the data loader pattern, this is just 3 calls.

Why is that a problem? As far as I can tell, those calls are all done on the server, where they're cheap normal function calls, and the results are all sent back with 1 roundtrip; because of the pipelining.

Super cool work!! How much of a limitation is it to have the robot be basically 3D-printable? Though I can see it's basically required for making it buildable by others.

The easiest thing to do is probably use A* to find the solution, then imitation learning on the NN to learn it. (The immediate feedback gets rid of the vanishing/exploding gradients problem).
