I'm extremely curious, what kinds of problems? We had entire Kubernetes nodes becoming unresponsive, and I think io_uring in Node 18.18.0 was responsible, but they had lots of stuff running on them so I was never able to pinpoint th

Why? They're going to be making this for years, and the issue must surely affect sales.

Although there's always luck involved, it was discovered by the Catalina Sky Survey, a survey specifically designed to spot near-earth objects. Their main telescope has a very large field of view (20 square degrees), and takes only 30

Does anyone know why they're building a high-capacity cable to Singapore instead of Sidney? Sounds politically much easier to use the power domestically.

I've worked in Go for two years, and I hate zero values with a passion. I would much prefer undefined/nil/whatever as a default value. At least that obviously represents an invalid value, and will crash on use, become `null

You've clearly never opened Kubernetes' source code.

> - A Go program runs single-threaded, unless you explicitly tell it not too, so I don't quite see that as a plus for Typescript. I don't think this is a fair comparison. Almost all software needs some kind of concurrency, and

It's better in Swift or Rust. Go channels are the worst thing about the language, even trivial use cases are difficult to get right.

I'd still be more inclined to blame a software issue. Do you have the exact same software installed on both?
163.
by sapiogram 2y ago
What you're suggesting is basically a worse version of adding built-in min() and max() to the C spec. Which, to be fair, would be quite nice, but I guess the working group didn't want it in the standard.

How did that end up happening? Did you define addition recursively or something?

> Well, clearly there is a need for a special value that is not part of the set of legal values. There's a neat trick available here: If you make zero an illegal value for the pointer itself, you can use zero as your "special v

No, the question is definitely applying a theoretical definition of C. The problem is that pointers are required to have a finite (but arbitrary) length, meaning addressable memory is also finite.

Makes perfect sense to me, it just means the language was already a year behind when it launched.

Disclaimer: I don't work in this field, just an enthusiast. As far as I can tell, branch predictors have always been too good for it to be worth it. Moderns CPUs have instruction reorder buffers that are hundreds of instructions deep,

I don't think AlphaZero is related to this work, apart from both being NN-based. AlphaZero and its training pipeline fundamentally only works for "chess-like" two-player games, where the agent can play against itself and slow

by sapiogram 2y ago
Only slightly more general. It only works for games that are zero-sum, deterministic, have no hidden information, and discrete game state and moves. Other examples include connect-4.

64GB ddr5 memory modules don't even exist yet, so going 128GB would require four memory DIMMs.

WaitGroup/ErrGroup doesn't even work here, because the functions return data. I mean, you can use ErrGroup, but it requires additional error-prone concurrency orchestration to work.

Non-native speaker here, what does "hard G" even mean? G as in "go", or G as in "gin"?

As strange as it sounds, this just seems way to sophisticated to be malicious.

Both statements don't need to be true. The compiler just has to prove that at least one of the statements will always be true.

As long as overall power consumption keeps decreasing, yes.
