Saying WebGPU “only” adds compute shaders is crazy reductive and misses the point entirely for how valuable an addition this is, from general purpose compute through to simplificat…

I massively disagree. It would have taken the author approximately 1 minute to write the following high quality hack-n-slash commit message: ``` Big rewrites * Rewrote X * Deleted …

There’s address sanitizer on newer versions of visual studio now but in my experience getting it to actually work with all of your projects’ dependencies can be very hit and miss. …

Really interesting article. For me this was an important takeaway: >Although it should fail gracefully, it does not need to be optimised for failure.

One thing LLVM bitcode still can’t do is retain information about preprocessor directives, eg any platform specific code for AVX2 vs SSE4 etc. So unless you aim to write intrinsic …

Though worth noting only for specific AVX-512 CPUs. Though you can still have vectorised support for regular precision for AVX2.

I have my own USB-C crappy story. I have a 2020 MacBook Pro 16” with bootcamp installed. Recently I bought a USB-C hub, if I try to boot into windows (hold alt at Apple logo) the m…

Depends on what you’re comparing to what. Big spinning lidars on cars are still expensive (few thousand dollars) but are coming down on price. Handheld 3D scanners on the other han…

I work at a company that does lidar SLAM. You can actually produce really high quality maps/slam with lidar/tof sensors, and it’s a lot more robust/dense than visual/imu mapping.

Maybe I screwed it up, I’m not the best developer ever. I took their sample code to extract the depth data from front camera and this worked - switching to .back caused it to retur…

I've had a play around with the new ipad. The big problem is (as far as I can see), absolutely no way for a developer to get access to the underlying depth data. I'm assuming it's …

Swift can also auto vectorise these simple loops, but only with the right combination of compiler flags. https://swift.godbolt.org/z/JmtOMx

I found this very interesting, particular the comparison to x264 (which I had never heard of). Looking into it I found x264 looked really easy to use with a nice C api but was enco…
