I think the point is just about temperature. I've experienced this out on lakes in the northern US for example. It's sunny but not like a tropical beach, and maybe even a little chilly. But you'll definitely get burnt without

In addition to godbolt and reading the output, the scalable check is just benchmarks. When you write new code that you want to autovectorize, you can check it in ways mentioned already. But then IMO the biggest downside of autovectorization

100%. I've always used youtube on desktop (connected to the TV usually), and it seems to me they're just making all versions of youtube into a mobile app optimized for shorts type content. Recommendations are hugely influenced by

Genuine question, but have you seen the popup being described? It's absolutely huge, and has a fake x button pattern. The complaint is on how disruptive it is, not the ask for donations

I don't think this applies to Python. There is a core team and there are expenses, but people do contribute code and work. Not to mention corporate sponsors. Sure, donate if you want, but it's not the same as blocking ads on purel

I looked out of curiosity and on my 15 inch laptop screen it does take up probably about 40%. I'm surprised by how egregious it is. And it looks like they changed it (or there's an A/B test?) since the thread. It also now jok

Yes, and on one request I saw a message like "Restarting server - this won't take long", and soon after it's back up.

I mean, do it if it's worth it. But the parent seemed to imply everyone should be doing this kind of thing. Engineering is about tradeoffs, and sometimes the best tradeoff is to keep it simple.

I'm definitely in favor of not pessimizing code and assuming you can just hotspot optimize later, but I would say to avoid reusing objects and using sync.pool if it's really not necessary. Go doesn't provide any protections a

Yeah, golang is a particular nightmare for SIMD. You have to write plan 9 assembly, look up what they renamed every instruction to, and then sometimes find that the compiler doesn't actually support that instruction, even though it&#x2

JPEG is similar actually. The DCT is invertible, but the result of the DCT is quantized, which is where some of the compression happens (DCT -> quantization -> IDCT), so the end to end process is not truly invertible. Maybe an analogy

Agreed it's missing that detail. I think it makes sense though that the durable queues shouldn't need strong consistency and transaction isolation, just durability, so the DBs can probably be sharded pretty arbitrarily, maybe oper

Fair enough, I was a little too negative. It is good they're thinking about improvements

Interesting that very few people in that thread seem to understand Go's model, especially the author of this proposal. If you don't allow preemption, you still have a sort of coloring because most non async functions aren't s

by ashf023 1y ago
All goroutines are async in some sense, so generally you don't need to return a channel. You can write the function as if it's synchronous, then the caller can call it in a goroutine and send to a channel if they want. This does f

"one obvious way to do something" describes almost none of Python. Easier said than done I guess, but I find Python particularly bad at it

If I understand it correctly, this is only catching ownership violations at runtime, so it doesn't actually prevent writing/shipping the bug? But it does seem to be able to improve the detection rate and determinism, and also help

by ashf023 1y ago
IMO pushing ifs up makes sense when the condition is enforceable by the type system, e.g. in the Option<Walrus> vs Walrus example, and when doing so makes the function's purpose more clear, or gives callers more flexibility. I th

Yeah I find this so strange. Why not take the opportunity to throw a bunch of heavily cached shorts recommendations in our faces when signed out? I don't understand how the anon home page is not both a money maker and extremely cacheab

100%. I work in Go and use optimizations like the ones in the article, but only in a small percentage of the code. Go has a nice balance where it's not pessimized by default, and you can just write 99% of code without thinking about th

sync.Pool uses weak references for this purpose. The pool does delay GC, and if your pooled objects have pointers, those are real and can be a problem. If your app never decreases the pool size, you've probably reached a stable equilib

This immediately popped into my head! I remember it blowing my mind years ago

by ashf023 2y ago
Yeah it's definitely similar to having parent nodes summarize their children. The motivation for the flat array structure was to have an entirely fixed-size array that's contiguous in memory to make it friendly for SIMD filtering.

Maybe an additional "lower resolution" index on top of the map could help as a heuristic to skip whole regions, then using the map to double check possible matches. I have a rough idea that I think could possibly work: Maintain th

by ashf023 2y ago
Gotcha. I wasn't quite sure from your post, are you storing free slots in the map, or booked slots? And do you know, for the cases that aren't fast enough, how much they tend to search through? Like are there just a ton of booking
