FYI you linked to a really old version of the GCC documentation. Google apparently loves those old docs, so they often show up near the top of search results despite being ancient.…

Historically, it was a bit more complex than that, and applies to more than just AVX-512: https://gist.github.com/rygorous/32bc3ea8301dba09358fd2c64e0... .

Zig vectors do not necessarily force data into SIMD registers; a scalar implementation would work equally well. This is not just a theoretical argument, because Zig code that uses …

It's not designed for IoT devices per se, the naming is just terrible. A comparison to OpenWrt is not warranted here, although to reiterate, the naming is terrible.

You're "supposed" to acquire LTSC through non-official means, not using the evaluation ISO.

Explorer uses XAML Islands. Parts of it are WinUI, while the rest is still Win32.

"Good enough" is not good enough.

There's a million and one ways to do it, here's just some of the ones I remember: - https://www.mdsec.co.uk/2022/04/resolving-system-service-num... - https://klezvirus.github.io/Re…

On modern enough x86 CPUs (Intel Broadwell, AMD Ryzen) you could also use ADX [1] which may be faster nowadays in situations where radix 2^51 representation traditionally had an ed…

According to the standard `realloc(NULL, size)` should already behave like `malloc(size)`. You shouldn't need that special case unless you're working on a system with a very buggy/…

It just uses GDI_CLASSIC for DWRITE_MEASURING_MODE [1] and DWRITE_RENDERING_MODE [2] in that case. No actual GDI in sight. [1] https://learn.microsoft.com/en-us/windows/win32/api/d…

The much dreaded Annex K functions are perhaps the worst possible example of an attempt at "fixing" anything safety related in C. A waste of ink.

Are there any benchmarks of Windows EH? The implementation is very different from DWARF/SJLJ EH and it would be interesting to see how it fares. I've seen some pretty exceptional c…

> Is a single MOV instruction still fast when the 8 bytes begin on an odd address? On x86, yes. There is no performance penalty for misaligned loads, except when the misaligned loa…

I think you should be able to get rid of most of the undocumented API usage with the newer CreateFileMapping2/MapViewOfFile3 APIs. Though that does require a higher minimum OS vers…

Be aware that if you actually want to do as the article prescribes, don't just copy and paste -- you shan't take anything at face value in C: https://news.ycombinator.com/item?id=3…

There is also Comic Code by the same author: https://tosche.net/fonts/comic-code . Feels like a more polished version of Comic Mono (but it is paid, too).

You don't need this exploit. You could use a media player that doesn't need MS codec packs, but assuming this is not an option: 1. Go to https://store.rg-adguard.net . 2. Paste in …

> is this possible or is the backend selected e.g. based on the OS? Selected in a reasonable order by default, but can be overridden. There are three ways to do so: - Set the SDL_H…

The current SDL GPU API does not intend to use this shader language. Instead, users are expected to provide shaders in the relevant format for each underlying graphics API [1], usi…
