“Phoronix, but high quality” would also be great. People kept asking if they could pay for AnandTech, and they said “we'll think about it” for years until they shut down instead because it was financially unsustainable.

Still, we're talking orders of magnitude here. I've fed Shazam with a stream of the cheapest lapel microphone you could get, mounted behind a rack filled with twelve very noisy servers, in a hall filled with 5000 people also all b

For me, mostly a lot of false negatives. I have a Pixel 8, and I have no problems using the microphone normally, but somehow, Merlin requires the bird to be within a couple of meters of me and sing for quite a while before Merlin will even

For any complex system, there's never one single trick or design choice that makes it fast. It's always a large amount of engineering (or exaggerations, of course).

> Yeah, it's not nearly as cool to say "I prompted a probabilistic pile of tensors and it did the hard work for me", and I think it majorly adjusts how "impressive" projects are. Vibe-decomped projects are also…

Yes. Especially when there are common libraries and you can reuse their names, structures or even entire decompiled routines. There's a fair amount of folklore going around, but less direct sharing than would be ideal.

> Historically there was a notion of "clean room" reimplementation These projects start off with the original assembly code and use it actively throughout all stages. This is about as far away from clean room as you get.

MP3 decoders have, thankfully, gotten faster since the 90s. But yes, a 66MHz is pushing it indeed.

Yes. Which matters a lot when you cannot just update OS kernels willy-nilly (most people did not have Internet connectivity, Windows Update did not exist before Windows 98).

Generally most forms of PGO does not try to capture number of mispredicted branches (which isn't the same as how often a branch is taken).

I once got that question, started with the keyboard switches and the interrupts, and the interviewer sighed and asked me to get to the stuff in the browser.

The demoscene still exists, although it doesn't seem to attain a lot of new members, and most (not all!) of the activity is back on oldschool platforms like Amiga or similar. See e.g. https://www.pouet.net/ ; Assembly 2

No, not really. Highway generates rather bad code as soon as you step outside a pretty narrow vertically-oriented scope, in my experience.

GF2P8AFFINE has entered the chat. (I've both played bridge actively and written SIMD code professionally, bridge rules are way simpler. Actually playing good bridge is probably harder.)

Interesting, but if you are not robust to corrupted/malicious data, it is really in a different class of algorithm and it is hard to compare speeds directly. From memory, 2505 MB/sec also sounds on the low side for LZ4 on a moder

I was at a talk where he brought up exactly this (I also once did a talk alongside him, but that's a different story). He said there would be two changes: 1. It would have 128-bit addresses. 2. It would have end-to-end encryption (or w

So, in your example, each request needs 0.1 core-seconds of PoW. Is that right? Or, since you're saying 10000 hashes across the entire machine and 1000 needed, then on a typical 96-core server you need 9.6 core-seconds of PoW? The form

I don't have a book, but my best recommendation would be: Learn how to measure. Whatever language you are using should have a profiler. Learn how to use it and look at how your code holds up. Look for surprises; those are optimization

This is called “installing a cryptominer on your web page” and is generally considered illegitimate.

That's a completely different question, your claim was about parallelism.

by Sesse__ 2mo ago
Uh, is it resistant to parallelization across multiple sites? Because that's the situation for the scrapers. They're not trying to solve a single PoW challenge across many cores.

The sad part is that most employers don't care particularly about performance optimization skills (the economics don't work out, they can often just fix the problem cheaper with more hardware—and even if they can't, they most

I once measured a 80s-communally-built event space with a laser meter (it was useful to have digital floor maps for event planning). No measurement was a perfectly round number. No angle was perfectly right. Nothing really lined up. Except…
