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This was true 4 years ago, but is outdated knowledge now.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.

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.

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.

Webp was not as exciting. JpegXL has cool features like 20% improved lossless jpeg recompression and progressive decoding. Not to mention all the cool stuff used in the writeup like implementing a font in the prediction engine.

> visual coding impeded their ability to learn text-based coding

As a former child, my opinion is the opposite. I learned visual programming with Lego Mindstorms NXT in ~2008, and later developed an interest in text programming on Roblox in ~2012. It's my belief that my fluency with concepts like control flow and values output from one part of the program serving as inputs for another part of the program were largely transferable to text-based programming. Learning a first programming language is 30% learning syntax, and 70% learning programming.

New comment by QuaternionsBhop in "Myths Programmers Believe about CPU Caches (2018)"

QuaternionsBhop — Sat, 01 Nov 2025 11:45:07 +0000

Since the CPU is doing cache coherency transparently, perhaps there should be some sort of way to promise that an application is well-behaved in order to access a lower-level non-transparent instruction set to manually manage the cache coherency from the application level. Or perhaps applications can never be trusted with that level of control over the hardware. The MESI model reminded me of Rust's ownership and borrowing. The pattern also appears in OpenGL vs Vulkan drivers, implicit sync vs explicit sync. Yet another example would be the cache management work involved in squeezing out maximum throughput CUDA on an enterprise GPU.
