In Tetris, you are supposed to have a "bag" of five tetrominos that are drawn from in random order. You can see the tetromino falling down and which one is coming next, and you know the one after that must be one of the remaining

I recently played Emacs tetris, and I was confused by how the tetrominos were selected so I dove into the source code to impress my boyfriend. It turns out that the tetrominos' behavior is configurable with a defcustom, but by default

I used to be excited about printing data layouts the way DDD or Rizin do it, but lately I've been getting into GDB pretty printers. They aren't very difficult to write (once you grasp the basics of the GDB API and compiler debug i

I love pwndbg. I work at the level of writing syscalls often, and it's wonderful that pwndbg's disassembler pretty-prints the operands of syscalls write next to the actual instruction.

QBE has no support for SIMD last I looked into it, so I don't think it would be appropriate for an SPMD language. https://todo.sr.ht/~mpu/qbe/5 It's common for shader compilers to invent their own IR, li

Not really. LLVM does support compute mode SPIR-V, and _very_ recently graphics-mode SPIR-V which is being dogfooded by the highly WIP HLSL front-end in Clang (I couldn't get a trivial fragment shader to build with it a few weeks ago).

OpenMP was pivotal to my last workplace, but because some customers required MSVC, we barely had support for OpenMP 2.0.

For what it's worth, a lawyer _did_ ask the presiding Judge Christopher Lopez to tell Alex Jones he definitely can't do that and solidify this in writing the terms of bankruptcy, and the judge simply refused to even try on the bas

I recently implemented a runtime for `__builtin_cpu_init()`, `__builtin_cpu_supports()`, and `__builtin_cpu_is()` for x86-64. Using these compiler intrinsics, or a higher level feature such as `[[gnu::cpu_dispatch]]`, you can write function

I'm confused why you insinuate that "flag waving" in June has anything to do with this topic. You frame it as though that is something developers tolerate because they are paid to, in contrast to how developers behave in volu

That is a completely intended way to use std::hash, along with a few other functions like std::tuple_size and std::tuple_element.

Clang supports C11 - 23 in C++, as well as some future C features like fixed-point integers. The main pain points with Clang are just the fundamental differences like void* and char, which don't typically matter much at an interoperabi

The first thing that comes to mind when I think "flux" is none of the above too . There's an extremely cool alternative iterator library for C++20 by Tristan Brindle named flux.

It's especially unfortunate that the intuitive name, `std::map`, is that ordered and generally least useful option of the standard library's three hash map containers. My last job did rely on ordered-ness of `QMap`, because the el

There already exist many affine-typed languages with fewer features than Rust. When you phrase it like "Rust but with weaker type safety and higher-overhead abstractions" one might see why this premise fails to gain much traction,

Intel also provides vtune to annotate sequenced instructions and profile the microseconds and power consumption down to the level of individual instructions. I assume those NOPs you mention exist for alignment padding. Clang and GCC let you

You still require a Vulkan driver to do anything with it. Until last year, Nvidia hardware required a proprietary Vulkan driver (prior to Nvvk), and anything pre-Pascal still requires that.

Clang, as a non-standard feature, allows you to put a type-id into `_Generic` rather than an expression.

by Conscat 2y ago
The former is more expressive because it doesn't require a template to manually deduce the underlying type of an enum as `static_cast<std::underlying_type_t<Permissions>>(Permissions::Read)`

I tried using `_Generic` inside C++ templates as a lighter alternative to `std::conditional_t`, but I was disappointed to find it didn't have short-circuiting semantics, which is my biggest pain point with `std::conditional_t`. If it w

That's an interesting note. I wonder why they claim this. As far as I know, `[[gnu::optimize("-fno-tree-loop-distribute-patterns")]]` (or the equivalent #pragma) is required for implementing a memcpy function in C unless you
