Blanket blocking socketcall() caused regressions for all 32-bit applications trying to make sockets. In theory, glibc disables socketcall when running on kernel version >= 4.3. In practice, Debian/Fedora/Ubuntu all set glibc&#x

I don't make any efforts to make mobile devices work, since usually their GPUs and drivers are not good enough for this, but PRs and patches are welcome. At one point Mobile Safari was working.

That Wayland keylogger is not the same thing. X11 has several mechanisms (XTest, XRecord, XI raw inputs) to receive a global raw key input stream, accessible to anyone who connects to the X server, without even making a visible window surfa

Most GPU drivers these days are DRM drivers, which implement fbdev support for backwards compatibility only [0]. The fbdev API is primarily "fake" these days. DRM/KMS using dumb buffers are the preferred API if you want to do

The words "virtual machine" and "interpreter" are mostly interchangeable; they both refer to a mechanism to run a computer program not by compiling it to machine code, but to some intermediate "virtual" machine

Every year they drop a "new GPU!" announcement with absolutely no details. All their numbers are "in simulation only". Last year it was their "Thunder" architecture being the world's fastest GPU, now it&#x

Basis also drops quality on the floor by targeting subsets (ETC1s and UASTC) in hopes of having a "common transcodeable subset". In practice, a number of runtime transcoders seem to just decode to RGBA and then fully re-encode any

Has anybody ever figured out what "invert a binary tree" means? That came from Max Howell, and nobody else seems to have ever received that question. The best anyone can figure out is that it's reversing the left and right br

metal-tt/metal-nt require you to specify the exact architecture, and that's not forward-compatible unless you update your application for every new device release. Even minor SKU revisions like applegpu_g13p/applegpu_g13g&#x2

Microcode was only used for the RSP, which was a modified MIPS coprocessor and could only realistically be used for T&L. After that, the RSP then sends triangles to the RDP for rasterization, pixel pipeline, and blending, all of which a

Ubershader actually has three different opposite meanings, unfortunately. The classic usage is a single source shader which is specialized using #define's and compiled down to hundreds of shaders. This is what Christer uses in that blo

Encryption without authentication is not very useful; if unauthenticated, your ISP could middle-man your connection and effectively decrypt everything while making you think you're encrypted. If that's not in your threat model, an

No, they don't do any of that. There are 100 different blockchain implementations at least, and none of them are standardized across any of those metrics. Everything from the consensus mechanism to the packet format to the bytecode is

The blockchain can't do anything with stablecoins, because that's interfacing with a financial system that's out of the reach of smart contracts. Even if we assume that a stablecoin is backed by real USD sitting in a bank acc

I'm not seeing what you claim to be seeing in that demo video. I see a per-triangle debug view, and a per-cluster debug view. None of that is showing repetition.
