Java Card is a very different language that's only superficially similar to Java. It prohibits OOP, only allows static methods, and makes you store everything in byte arrays and use System.arrayCopy. It's basically a less convenie

Are you kidding me? It was all basically vaporware that disappeared when the free money ended. The Kiwi food delivery robots were basically fake -- they only went about 1/8 of a mile automatically. So they'd drive a car to the end

Basically, if you have one piece of codebase call gl.enable(gl.BLEND), then either that needs to reset it at the end with gl.disable(gl.BLEND) and you have some vague ambiguous default state that everything enters and leaves. If you don&#x2

Most people that want to keep using OpenGL would be better served by a cross-platform D3D11. WebGPU is similar-ish to that.

I think OpenGL and Vulkan fail at opposite reasons for this. OpenGL is a giant ball of yarn state machine that's way too complicated to drive and doesn't do what you want. Vulkan requires spelling everything out in excruciating de

I'm a graphics programmer who has quite a bit of experience with WebGL, and (disclaimer) I've also contributed to the WebGPU spec. > Quite honestly, I have no idea how ThreeJS manages to be so robust, but it does manage somehow

MIDI does not have a sound. It's just instrument data. The classic "MIDI sound" that you recognize is the Roland GM soundkit shipped with Windows (an early version of Roland's Virtual Sound Canvas product). This website

The N64 has no native sound processor -- just PCM sample output. Game developers often integrated some form of custom sequence or MIDI format, combined with PCM samples, and some playback code running on the N64 CPU. The miniusf file format

foo += 1 was never atomic. It always compiled to something like: LOAD_FAST foo LOAD_CONST 1 BINARY_OP + STORE_FAST foo The GIL only protected you during any of those operations, so you can still switch threads waiting

You can build far better abstractions than what we have here. A lot of games that support more than two platforms have graphics abstractions that leak less than this.

It's a very weird one. createRenderPipelines uses the branch to add #version 460 to the beginning of shaders (one would think the platform backend could do that for you, also this won't support GLES2 or GL3), and also makes the pr

Even outside of platform-specific stuff, I'm seeing it all over the core rendering code. I'm not impressed. https://github.com/facebook/igl/blob/main/samples/desktop/Ti...

For small triangles, they use a software rasterizer into the V-buffer. Obviously for 1px triangles since they don't want to waste quad overdraw, but I think they found it's faster up to 12px/tri or so on AMD.

X is color-managed to the same degree that it is in Wayland. That is, all buffers are sRGB, and the application needs to convert output buffers in sRGB format. Chrome certainly takes great care to do color management of the content displaye

All Wayland compositors I am aware of use KMS planes to push a hardware cursor plane. It should work fine.

I certainly have some complaints with Wayland's design, but I'm curious what you would remark as dealbreakers here. As someone intimately familiar with both X11 and Wayland (and used to maintain stacks for both), Wayland is a real

X is not color-managed either.

Grayscale AA is still common on Retina screens, but subpixel AA is rare. Mostly because subpixel AA is difficult to do compositing with transparency with, but also because it's less necessary on Retina screens. The tradeoffs are just t

Oh, I was assuming it was occupied by an enemy piece, and would capture it. You're right that if it was occupied by an allied piece, it's not a legal move.

The form factor we have now is basically identical to what headsets looked like in the 80s and 90s [0]. They are barely smaller than they were back then. The problem is not the computers, it's the optical pathway. You can't shrink

That would lead to inconsistent brightness across devices -- white on a 2000 nits HDR TV is extremely bright, you likely don't want that as a paper white background. Standardizing on some good enough value of nits (usually between 80 a

Except constexpr isn't a guarantee. Compilers can choose to silently evaluate constexpr things at runtime. And I have ran into this before: a compiler with a recursion limit causing it to bail on constexpr and just emit the code. So

In the same way that you are still trespassing even if you can easily step over a fence saying "no entry". Try going to a judge and saying "well the sign lied, because yes I was able to entry when it said I shouldn't be
