If one lidar hits another, it will result in at most one bad reading (perhaps a bad column?). This can likely be filtered, or a bad scan (360deg) can be altogether rejected and the…

That's a pretty good example. The summary is actually useful, yet it still annoys me. But I'm not usually reading the comments to learn, it's just entertainment (=distraction). And…

Interesting example! I've been learning AVX512 by using it to optimize Huffman coding. I found _mm512_permutexvar_epi8 and used it to do byte-indexed lookups, but _mm512_permutex2v…

Also just stopped reading at that point. The idea seemed quite clever.

The peak of human civilization, before robots took over.

I could be wrong but I think many times the researchers don't care about the exact function. It could be something like 1/log(log(n)) .

https://yuri.is/not-julia/ is a good write-up of one person's opinion on the problems of Julia. I'm much less experienced with Julia but I somewhat agree. There's too much focus on…

He says he'll port his performance optimizations to the original game once he's done with his game / romhack. Otherwise he'd have to always update two codebases when he finds a new…

Back then I remember switching to Chrome for these reasons: 1. Feeling faster than firefox (still does) 2. Process separation for tabs. Firefox used to crash the whole browser, whe…

Exactly. It could even be turtles all the way down, with new building blocks of physics becoming relevant as we go smaller and smaller (and back in time).

Would that be morally close to torturing an equally intelligent real worm?

It's jarring initially, but becomes natural very quickly. Writing loops like "for i in 1:length(arr) ... end" is pretty neat compared to C++ or even python. Plus in math sequences …

It is nitpicky, but the fact that these classes deal with decision problems and not general problems is something which feels like should be mentioned more often. Of course this en…

This would make sense right? You probably can't run all cores at max turbo frequency before hitting power and thermal limits. So dividing chiplets based on binning would result in …

I thought google did this versioning thing for libraries before, but it was stopped for reasonable reasons (g3 components). Basically if you could pin lib versions everyone would b…

I can believe this. Around the time I left people were patting backs for fighting racism by getting rid of terms blacklist/whitelist. Not something I feel super strongly about, but…

There's very little you need exceptions for with STL. Data structures, algorithms, etc. all work just fine without exceptions. C++ without exceptions is great. Google doesn't use e…

You can buy drugs and other illegal things off the internet (tor), that's very useful for some people. Basically crypto allows for transactions that could otherwise be blocked or e…

There doesn't even have to be a conspiracy for this to occur. Companies always want to seem like the good guys, so they'll jump on any trend that doesn't hurt them. BLM, LGBTQ+ ( )…

Who are they asking for the data? ISPs, USA today, NSA?

To verify a single transaction, the network uses 1150kWh of energy which produces 550kg of CO2 [1]. [1] https://digiconomist.net/bitcoin-energy-consumption/

To discourage people from finding the box inside, we could insert traps to hinder explorers.

There's a lot of convenient new instructions in avx512 that can work on 128/256-bit vectors. I'm guessing that those wouldn't throttle more than regular avx.
