Note that compilers are more than happy to delete 'while (true)' if the loop doesn't have side-effects.

I understand this logic, but at some point it makes sense to design the system for the millions of people on macs rather than make compromises for the sake of dozens of Vision Pro users.

Is there a technical reason why apple doesn’t allow HDR to be selectively turned off? I’m surprised this is still not at least an accessibility option.

Compilers can’t really, in a meaningful way, change the layout of your data in memory. And you do need to think about your memory layout to get any benefit from SIMD. You’ll notice a lot of compiler auto vectorization insert many instructio

Lenovo is the “weird exception” because thinkpads have always had the Fn key on the bottom left. Just like they still keep the track point. I would presume most people buying a thinkpad don’t want to buy “the vast majority” of laptops.

I had no idea they used the Plan 9 file server for accessing files in WSL. I wonder what the original reasoning for choosing 9P was.

For GeForce cards you can get similar behavior by setting “Prefer maximum performance” which disables some of the low power states.

Designated initializers is one area where C feels much more expressive than C++. And that feature has been standard since C99.

Vulkan is a pain for different reasons. Easier to install sure, but you need a few hundred lines of code to set up shader compilation and resources, and you’ll need extensions to deal with GPU addresses like you can with CUDA.

I mean it kind of is considering that's comparable to a 5070 which has 672 GB/s? Benefit of NVIDIA being the only one using GDDR7 for now I guess.

I've always assumed minifiers were a kind of lossless compression. I guess this optimization makes it lossy? Even if we can't tell the difference between oklch(0.659432 0.304219 234.75238) and oklch(.659 .304 234.752) they're

When you're using a programming language that naturally steers you to write slow code you can't only blame the programmer. I was listening to someone say they write fast code in Java by avoiding allocations with a PoolAllocator th

This comment assumes game companies throw away all their code and start from scratch on their next title. Which is completely untrue, games are built on decades old code, like most software. There is absolutely a need for maintainable code.

For a graphics programmer acos(dot(x, y)) always raises an eyebrow. Since most of the time you actually want cos(theta) and even when you think you need the angle you probably don’t.

Compilers cannot do this optimization for floating point [1] unless you're compiling with -ffast-math. In general, don't rely on compilers to optimize floating point sub-expressions. [1]: https://godbolt.org/z&#x2F
