Do you have any view on why the AI scrapers resulted in a heavier load than existing crawlers from eg search engines? Where they more exhaustive or more frequent?

It can work when the marginal cost of new capacity is high, compared to existing capacity. E.g., if the marginal cost of supporting 1 kW of new capacity may be X, while the current…

Wafer area?

> The most insane part here is that the AMD EPYC 4565p can beat the turin's used on the cloud providers, by as much as 2x in the single core. That is ... hard to believe for a CPU-…

What I mean is that we look at a function in isolation and see that it doesn't have any "dead code", e.g.,: int factorial(int x) { if (x This doesn't have any dead code in a static…

Why is that a problem? Inlining and optimization aren't minor aspects of compiling to native code, they are responsible for order-of-magnitude speedups. My point is that it is easy…

Dead code is extremely common in C or C++ after inlining, other optimizations.

Relevant section: > Compiler controlled memory: There is a mechanism in the processor where frequently accessed memory locations can be as fast as registers. In Figure 2, if the ad…

More registers leads to less spilling not more, unless the compiler is making some really bad choices. Any easy way to see that is that the system with more registers can always us…

User variance? Any evidence?

How does prek handle pre-push hooks? I.e. how does it determine the list of modified files. This is a long standing sore point in pre-commit, see https://github.com/pre-commit/pre-…

If you had a shell script hook, yes you would also run that in CI. Are you asking what advantage pre-commit has over a shell script? Mostly just functionality: running multiple hoo…

They integrate well with CI. You run the same hooks in CI as locally so it's DRY and pushes people to use the hooks locally to get the early feedback instead of failing in CI. Hook…

Critical section was IIRC built on top of windows manual/auto reset events which are a different primitive useful for more than just mutex but without the userspace coordination as…

What is a BM?

What is the point of the intent entry at all? It seems like operations are only durable after the completion record is written so the intent record seems to serve no purpose (unles…

No there are vanilla 64GB shipping now too, e.g. Crucial CT2K64G56C46S5.

Writes to the log don't need to be in the order of the producers timestamp, they just need to be in some (and respect ack to produce causality, etc).

Yes, I rely heavily on ^ and ' in antuin, though that's partly to workaround the relatively poor fuzzy search (in fzf I never even needed those).

I use Atuin and like it a lot, and sync history across hosts. However, the fuzzy search in Atuin is worse than fzf, which was a downgrade. It just has less effective heuristics/sco…

What is a late slip?

Uncontended CAS without carried dependendies on the result (almost always the case in this use case) are similar in performace to atomic add on most platforms. The CAS is the price…

Yeah exactly, and this is a commonly used trick in concurrent data structures in general. The Java implemenation has the additional twist that they don't use a fixed number of "slo…
