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 data predicted using models based on past sensor readings.

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 similar to images or videos, I find human-cr

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_permutex2var_epi8 means I can get by with 2 shuffles and 1 compar

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

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 "magic" inst

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 optimization.

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, whereas chrome would crash just a single tab. 3. Shipped with s

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 typically start at index 1.

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 ends up not mattering in practice since we can convert a probl

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 good performance for 1-8 -threaded tasks while reducing

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 be stuck on old versions for a long time, causing difficult d

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 the fact that it's so scary to go against these s

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 exceptions and they still use STL. Gamedevs usually

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 easily tracked by central parties (1). It can also be us

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+ ( ), etc. are issues that companies don't h

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.

WhatsApp would still be plenty incentivized to make their software secure. They understand that this wouldn't get rid of the exploit market, or state actors. I'm sure WhatsApp has been focusing a lot on security lately because of

Exactly. Having the experience of solving difficult algorithmic puzzles under time pressure makes parts of software engineering (writing working code, debugging) easier, so you can focus on the hard parts. Algorithmically, almost anything w

I've experienced the same, although I don't think I stress out about flights anymore. My theory is that it's caused by air being dryer in the plane, as my lips are usually chapped on/after flight.

The system is clearly not decentralized, if one organization can hold your funds for "misbehavior".
