I partnered up with Mirek (of Mirkotronics / @Mirko_DIY on Twitter) to build the Pi4GPU (or 'PiG' for short): This journey started almost three years ago: almost immediately after the Raspberry Pi Compute Module 4 was launched, I started testing graphics cards on it. First I tried some low-spec cards like the Zotac…
Having spent a lot of the last few years worrying about the scalability of data-heavy applications like Rapportive , I have started to get the feeling that maybe we have all been “doing it wrong”. Maybe what we consider to be “state of the art” application architecture is actually holding us back.

From paged attention, continuous batching, prefix caching, specdec, etc. to multi-GPU, multi-node dynamic serving at scale.
In the last post , we described a protocol that should satisfy the requirements and invariants established in the first post . Today we will look at formal verification with TLA+. Formal verification is just another (niche) tool in the toolbox. Some tools require more skill than others to use. So

Despite all of its warts, I like working in Linux. I've used it for 15 years and I've never been as productive in another environment. Most people claim that it's the configurability of Linux that keep the users coming. That may have attracted me at first, but what attracts me now is its programmability.
About two years ago I came across a .DS_Store file and wanted to extract its information (e.g. file names). After researching the file format and its security implications, as well as writing a parser for it, I would like to share my (limited) knowledge and the parser in Go / Python with the world. You might want to…
I examine the somewhat surprising way how Linux handles writes.

The Great Renaming FAQ
When I look inside a chip from the popular 7400 series, I know what to expect: a fairly simple die, implemented in a straightforward, cost-e...
Hmph! Not sure which one is "correct" there... hmm... If you use kCGImageAlphaPremultipliedFirst for the CGBitmapContext rather than kCGImageAlphaNoneFirst, then it looks closer to the original, maybe. ? Also other caveat: NSBitmapImageRep can't seem to deal with the ARGB format either, so if you use that you need to…
