For anyone else wondering what Loom is, it's a concurrency permutation testing tool in Rust: https://docs.rs/loom/latest/loom/

You're just offering non-helpful ivory tower criticism without even understanding the problem space (which is actually one of the hardest open research problems in software engineering, cs.PL + formal methods). But if I'm wrong, d

This is only applicable to die photographs of the silicon layer. For CT scans, which use X-rays, the visible structure is very likely due to the metallic (copper) interconnect, clock- and power-delivery layers, which are generally quite d

No... Adaptive sampling is a family of statistical methods to choose an appropriate decimation strategy for arbitrary events based on real-world occurrence distributions. It can be applied to tracing, metrics, logging ("sampling")

I think you overestimate the amount of senior engineers... even at the extreme end of top-tier big tech, only around 30% can be considered senior. Staff engineers who regularly think at the level GP talks about are 5-10%. Everywhere else

What? All of this has been solved for a long time. How do you think hyperscalers do this? Search keyword: "Adaptive sampling"

Yeah, it's very likely GLM. Trick: it's easy to check this - just try eg. a specific short almost-nonsense high-entropy phrase such as "Scarf Color Plump 蘼撅" via OpenRouter using the playground for different providers&#x

(as I and others have mentioned in the thread): The attacker can just move the malicious code from build.rs to lib.rs (ie. build-time -> test/execution-time). Then the problem is the language, as the grandparent observes.

The only safe solution is to review all the code's changes (or trust someone else to do it). Forbidding compile/build-time shenaningans is trivially bypassable and has already been bypassed in the NPM ecosystem by just making the

The slightly sad part is that most of these LLM-assisted fixes probably never make it upstream, so life for non-technical Linux users does not improve... If you do AI fixes, for the greater good, at least publish them (or even better, try t

Do you have any more insight into its progress? Seems like it's far from production-ready and there hasn't been much activity this year?

WASM is not a substitute for Fil-C. WASM is not memory safe in the same sense, in particular, heap corruption vulnerabilities still exist, which could eg. allow bypassing auth, leaking private information etc. C compiled to WASM is still vu

Naah. Solvable by turning the usual C library allocation pattern inside-out: Only the C side allocates, Rust gets views of that memory. Also well established - calling WebAssembly components requires exactly the same pattern, as the only wa

Errrrr... how is the first paper related to A* and path finding? It's about "planning" (ie. searching an action space) which does not generally have a heuristic, so it needs to do "exploration" (which is exactly the

Choosing 8×8 blocks is very likely highly suboptimal when it comes to the quality of the codec. The point of the 4×2 tiles is exactly to avoid the blockiness artifacts of vector quantization (visible in the article). Larger tiles increase

I didn't imply that you were being insincere... re: the greeting, I think introverts around the world do not necessarily appreciate being randomly greeted by strangers, they just get used to it if the culture is like that. From that

> Smiling at strangers is considered poor social form here and it doesn't matter if you're a foreigner or native. It's not. Insincerity and mindless, automatic smiles might be a little bit frowned upon. Genuine, but subtle

I think these esoteric workarounds required for what are trivial operations is why people use Jujutsu, which just has first-class "new", "squash" and "split" commands which can do all of the above intuitively,

The alternative has bad ergonomics, chained `.get`s which are the most common operation become: json.asObject().get("prop1").asObject().get("prop2")...

Misleading article. Probably partially AI written? Presents nonsense such as eg. the diamond inheritance example as valid-seeming argumentation. Quite a few points are plain wrong and outdated and under-researched, eg. Python has uv, ruff a

What's the advantage of this over Jotai / atomic state / computed signals, which seems to require 10× less code with mostly the same benefits?

Ugh, please don't read strawmen into other's arguments and try to follow the HN guidelines. Also, how about making proper arguments yourself? The vast majority of the training data isn't generated by company-paid AI experts

Indeed, that's exactly why I replied - you omitted one side from the discussion.

...and the rest of the training data (ie. the entire corpus of copyrighted works) was not written by experts expecting compensation? Double standards.

Ideally, yes. Depends on the context. Same way you don't use unit algebra when doing trivial everyday math. At some level of complexity, it becomes worthwhile.

This is like a type theory question - do you like it untyped or typed? In physics, values have units too. Analogously, you could say - why incorporate units into the algebra in physics (as is often done)? Why not just add scalars etc. and

Could you actually explain/exemplify any of the gotchas and what's been made better (or is this just handwaving)?
