Jokes require mutual context. You failed to create a joke because you did not ensure the prerequisites were met.

Is pasting em-dashes everywhere some kind of inside joke?

Minecraft (and Java) just runs great on Linux. I've personally experienced a 30% performance improvement from Windows.

I recently wrote klondike in Rust after getting frustrated with bugs in my friend's LLM-written version. I highly recommend it as a recreational programming exercise, the first 4 hour blitz filling out the types was a blast. Later, trying to make as many invalid moves unexpressable by the given types as possible was a fun challenge. I ended up with a 232 byte struct for the board state with all values stack-allocated. The only way to make it considerably smaller would probably be to encode card permutations.

This is great news for nvidia users on Linux. It means that they don't need to install a VAAPI compatibility tool like nvidia-vaapi-driver. I also hope to see Vulkan Video supported in the open source userspace nvidia driver NVK soon too.

Base conversions are easy, but which off by one is it? base 4 or base 6?

> I wouldn't recommend using Nvidia on Linux though.

This was true 4 years ago, but is outdated knowledge now. Nvidia used to disallow distributing drivers with distro images, but they have since made agreements with some popular distros. If the distro image you download includes drivers or you know how to install them, the proprietary drivers work really well.

> You can't rely on server-side detection either, because some of the cheats are so advanced they go to great lengths to "behave" like a highly skilled human player would with their aiming

Shouldn't that be the goal of anti cheat? That cheating is indistinguishable from expert gameplay? Seems to me like these companies are just trying to avoid implementing proper infallible server-authoritative gameplay by offloading the cheat detection to the untrustworthy client, and then trying to lock down the client to make it trustworthy.

This happens to me too. Often my dream plows forwards with unsound assumptions and I wake up believing something confusing.

This is called the AI Stop Button Problem. Computerphile has a great video on this (featuring Robert Miles) which explains why this is not a reliable solution to AI getting out of control. When the AI is smarter than all of humanity combined, the only real solution is for the AI to not get out of control in the first place.

I also invented this! There is cool stuff like angle adding and angle doubling formulas, but the main downside is that you can only directly encode 180 degrees of rotation. I use it for FOV in my games internally! (With degrees as user input of course.) In order to actually use it to replace angles, I assume you'd want to use some sort of half angle system like quaternions. Even then you still have singularities, so it does have its warts.

> Reasoning about code written this way makes me experience profound fatigue and possess an overwhelming desire to return to my domicile;

I didn't understand that you were making fun of verbosity until the word 'domicile'. I must be one of those insufferable people who expresses simple thoughts with ornate vocabulary...

The article was comprehensible to me, and the additional function colorings sound like exciting constraints I can impose to prevent my future self from making mistakes rather than heavy winter gear. I guess I'm closer to the target audience?

The fact that LLMs pick from the most likely tokens is really on its side here when the objective is putting together a plausible continuation of random characters.

New comment by QuaternionsBhop in "Rust--: Rust without the borrow checker"

Fighting the borrow checker is something you do when you're learning Rust. After you learn how to design things that way in the first place, it's just there to keep you honest.
