When I need something like that, I usually passing [ 0 .. 1 ] float phase to the shaders, and when updating the number on CPU I wrap the value into that range after the increment.

This is wrong for so many reasons. The root problem, democratic Ukraine presents existential treat for Russian autocrats. Donbass is not an independent entity, it's part of Ukraine occupied by Russians in 2014, under full Russian contr

Good one, but IMO a bit too expensive for the specs. I recently got a new laptop with Ryzen 5 5600U, 32GB RAM, and 2TB SSD. The laptop is HP ProBook 445 G8. RAM and SSD were sold separately, the upgrade only took 10 minutes and 6 screws. I

Interesting idea, installed the addon. I’m using MS Edge BTW, Microsoft doesn’t care about Google’s advertisement revenue, the addon is available in their marketplace.

I don’t think it’s possible to fix wealth inequality in any reasonable way. Here’s a trivially simple numeric simulation of zero-sum economy of 100k people: https://gist.github.com/Const-me/4b9b4372ba37c03feaf2f1475b1..

Why aren’t you using higher-level memory safe languages for that? In C#, the runtime checks for integer overflow can be enabled with a single compiler switch. The switch is not set by default for some reason, but easy enough to enable manua

Speaking about pre-shuffling and blending, you can try doing twice as much work with vectors. Pre-shuffle slices of 32 keys into [ 0, 4, 8, 12 .. ], [ 1, 5, 9, 13.. ] etc, then when searching combine 0-2 and 1-3 pairs of vectors with _mm256

Technically, sure. But practically — what’s your estimation how many C++ programmers target anything besides these 4, gcc, clang, vc++ or intel? My estimation is [ 0.1% .. 1% ]

No, but it’s supported by all modern compilers. In practice, that’s almost as good as being a part of the language standard. The level of support varies, but OpenMP 2.0 standard is supported by all 4 of them.

That's not the right move. The right move would be a sandbox around every word/excel file being viewed/opened. Ideally, backed by a kernel mechanics such as CreateRestrictedToken WinAPI. What they are doing instead, shifting

I like many parts of COM, but I believe that example mostly demonstrates bad parts, with IDL, registrations, and over-engineered support libraries. There's nothing wrong with exporting factory functions from DLLs. Microsoft does it all

Can it be that you linked to one of these libraries, but never called any function from that DLL, so your linker dropped the unused DLL dependency? However, I don't really like that method. The app will fail to launch on computers with

About switchable graphics, nVidia APIs do work. The problem with them, there's no API to switch to the faster GPU, they only have APIs to setup a profile for an application, ask for the faster GPU in that profile, and the changes will
