If you think directly calling Windows syscall is crazy, some applications parse binary code from ntdll.dll to figure out what the syscall numbers actually are, since they change ac…

It's a bit different. WoW64 is the technology used to run 32-bit applications on 64-bit Windows. Wine has support WoW64 for a long time. The difference is the "old" wine WoW64 mode…

> who are the devs of Wine. they employs many devs of Wine (including the project lead, Alexandre Julliard). but technically Wine is still an independent open-source project, and h…

That's a cool find. I wonder if LLVM also does the other way around operation, where it pattern matches handwritten CAS loops and transform them into native ARM64 instructions.

CodeWeavers, which I am very lucky to be part of, is also an (almost) 30-year-old small company! We make Wine, Proton, and CrossOver, you might've heard of them. And I think we are…

Any autoregressive model can do what you are describing. transformers are generating one token at a time too, not all at once.

i'd say it's mostly due to linking. the debug info generated is absolutely enormous.

I (kind of) know multiple languages and they all have different word orders. I find it interesting that my brain is able to switch from expecting information to be received in one …

I suspect the models probably memorized some chess openings, and afterwards they are just playing random moves with the help of the grammar.

Okay, I can't believe I am going to defend performance reviews (I hate them with passion), but I actually disagrees with the author's main point. Same accomplishments can be colore…

I had the pleasure of reverse-engineering win32 SRWLOCKs, and based on the author description of nsync it is very close to how SRWLOCK works internally. Kind of surprised how much …

This is pretty dumb on Debian's part. First of all I don't understand why they insist crate dependencies must be pulled from their repository. They are just source code, not built …

I am split on this. Maybe I am idealistic and naive, but I will always wish people can just stop fighting, and work together. Fragmenting the community and starting a project out o…

Congrats! :) BTW, instead of max(min()) when I wrote mine I used this equality: V'(s) = 1 - V(swap_players(s)), where swap_players(s) switches X and O pieces. And I only need to do…

Yep, this is what I ended up doing as well! With how the game generate boards, the player that goes first always have a ~5% advantage. Since players switch hands each around they s…

Turns out linear programming is not fast... Takes about 90 minutes to find the optimal solution for any board configuration.

I think this is doable. Say we assign a win rate W(S) to each board state S, and let W(S, A) denote the win rate after taking action A from state S. Since the transition is probabi…

I have a similar project too! I have an e-ink display connected to a Pi Zero that shows just a "Yes" or "No" telling me if it's going to rain outside in the next three hours. (On a…

Author here. I probably should have stated this more explicitly in the article, but my main concern with using it for day job is copyright. I don't want to accidentally commit copy…
