Xor isn't Turing complete sadly.

It's not UB. Integer promotion applies, the signed int is implicitly coerced to unsigned (or the other way around - don't remember which.)

Yeesh, one illegal move attempt means you just lose? That's harsh...

Javascript/PCRE/etc regexes have additional features (like backreferences) that give them strictly more computational power than a regular DFA/NFA. (Still not Turing complete though without external control flow to support arbitrary iteration/recursion, like is done here)

So it is NP (in fact P)

We Americans can't understand ourselves either.

Nintendo Switch does not run Linux, it runs a proprietary OS called Horizon based on the Nintendo 3DS firmware. Not sure but it might or might not have some BSD code in the network stack or something.

I'd bet even more Linux usage is ChromeOS which even more barely counts, and certainly both are dwarfed by Android which simply doesn't count.

It's like simple n-gram Markov chain algorithms vs modern LLMs for text

Read that as "only depends on the base dotnet runtime." I think the C# compiler at least can emit native code these days, but I'm not primarily a dotnet dev either so not too familiar with that.

New comment by benchloftbrunch in "The 1987 game “The Last Ninja” was 40 kilobytes"

benchloftbrunch — Mon, 06 Apr 2026 12:39:42 +0000

27 unique levels. 40KB minus a handful of spare bytes and some unused code. The max the NES can support without mappers. Modern NES homebrew and demoscene can do fancier stuff with this budget given the extra decades of learned tricks, but for the state of console gaming in 1985, SMB1 is damn impressive.

Also remember all of that was ROM, the NES had a mere 2 kilobytes of RAM for all your variables and buffers.

Best (for older kids) would be a dumb cell phone like we had in the 2000s. Good for phone calls, texting, and simple offline apps like casual games, camera and music player. Maybe email. Definitely no web browser, youtube, or social media crap.

I don't know the extent to which such devices are still manufactured today.

Problem with f16 is that hardware support is still "new" and can't be relied on in consumer grade CPUs yet.

GP is asking about the text prompt itself, not the generated image. If pure text can qualify as CSAM in Australia then it's a logical question.

benchloftbrunch — Mon, 05 Jan 2026 07:46:21 +0000

Question: why did they decide to make /usr/bin the "primary" and /bin the symlink? Methinks it should have been the other way around as was the original Unix design before the split.

Also the first URL is serving me scam popup ads that do a crap job at pretending to be android system alerts. Next time please try to choose a more reputable source.

Thankfully it's trivially easy to disable OneDrive via the task manager startup tab. Never had any issues with MSFT sneakily turning it back on either.

This super aggressive OneDrive shit is also why I've stopped putting most things in the standard folders and now just have my own alternative hierarchy in %USERPROFILE% instead.
