Have you started in on trying out openzl on an bfx formats? It looks very promising!

Any recommendations for a github CI plugin for performance monitoring?

Thinking of using github-actions-bench [0] which makes decent plots, in combination with maybe iai [1] for measuring CPU cycles (wall-time is too flaky in GH actions).

To be fair, Perl was the OG write only vibe coding language.

Another deep dive in the technology behind Conda package managers: file linking! Did you know that there are symlinks, hardlinks and reflinks? Reflinks are the best – copy on write is space efficient and isolates the cache.

What linking means when installing a Conda package

Package managers face a fundamental challenge: how to efficiently place files from a package cache into multiple environments without excessive disk usage or compromising isolation.

It’s come up for me! As a link specifically.

I’ve been wondering how Perl would fair with an llm. It manages to pack so much context into so few characters, it kind of seems like it should be great for llms?

I have no idea how to go about proving it is “good” or “bad” for an LLM though.

That’s fair! And I don’t have any better solutions.

Based on the linked AVX2 feature share in my other reply, hopefully we can widen the “generic” simd support in compilers here at some point

They support/ run CI for the large Hw groups like Linux-64, linux-aarch, osx-64, etc.

Some good HW stats: firefoxgraphics.github.io/telemetry/#v...

If v3 is around 75% in consumer PC, it’s got to be 90%+ for the HW for BFX

That compiles it on the CI machine I believe, so you can’t target the end user CPU features :(

You kind of can with conda features, but it’s a big pain and not standard that I can tell.

It causes me great pain that all these tools we install with conda are basically stuck with sse only

Thoughts on Rust hashing

In languages like Python, Java, or C++, values are hashed by calling a “hash me” method on them, implemented by the type author. This fixed-hash size is then immediately used by the hash table or what...

It might have been about array/range and their relationship with Iterator/IntoIterator

@steveklabnik.com Did you write an article about ways you wish Rust Iterators had evolved differently? Or remember who wrote that?

Mojo is about to start in on its iterator abstraction and I was looking for lessons learned from Rust, but can't find that article.

I might be imagining this it 😬
