Catherine (Whitequark)’s recent observations on poorly-engineered firmware reminded me of a few mistakes I’ve seen in vendors’ CPUs; some unimportant and others surprisingly bad. Since I’ve never seen these widely discussed, here’s some discussion and links to supporting evidence to make them more widely known, since…
Building httpz, a high-performance HTTP/1.1 parser with zero heap allocation using OxCaml's unboxed types, local allocations, and mutable local variables.
Scaling is a complex topic, but after working at big tech on services handling millions of requests and scaling my own startup (AlgoMaster.io) from scratch, I’ve realized that most systems evolve through a surprisingly similar set of stages as they grow.
Sometimes an article starts with a simple question or a single message on one of the available social platforms. This is the case today with this article where @ooberober asked: How small can the r…
The AI surge has DRAM producers like Micron focus on HBM (High Bandwidth Memory) to serve AI hyperscalers over the DRAM (Dynamic Random Access Memory) used by ordinary consumers and small businesses. Consequently, for instance, servers which used to cost $2500 on Newegg now cost $5000. RAM alone is $2500 now.
I love Rust and I love SQLite, so you can guess. Iwas pretty excited when I lerned that "SQLite was rewritten in Rust" What is SQLite, actually? 2 things: a
I found this tiny fanless Thunderbolt 25G Ethernet adapter. With a little tinkering, it actually works.
In the world of matching decompilation, projects use a tool which consumes an input binary and lifts objects for comparison and linkage.
Today we're comparing one of each generation of Pi from the Pi 1 to the Pi 5 to see how their performance and specifications have improved.
In 1978, Intel introduced the 8086 processor, a revolutionary chip that led to the modern x86 architecture. Unlike modern 64-bit processors,...
I made my next game twice as fast by forking go's crypto library
Update: I've since added multithreading and pushed astroz to 326M propagations/sec. Read the follow-up → I've spent the past month optimizing SGP4 propagat...
In a quest to reduce the number of processes running in macOS Tahoe, consider the example of Time Machine backups, which can easily be replaced by 3rd party alternatives.
Internet Archive Staff Bruce Li introduces his The Long Now of the Web: Inside the Internet Archive’s Fight Against Forgetting thus: Thi...
Archiving 104K files into tar.gz reduced I/O time by 43x and total processing time by 2.3x. The bottleneck was not disk speed, it was syscall overhead.
Creative ideas for speeding up queries in PostgreSQL
I've recently tasted AMD Zen 5 CPUs (AWS' m8a instances) and... Whooaaa. Even before talking about GPUs and NPUs, the next 5 years of CPUs will be very exciting! For
Recently I came across Lunduke post about some mysterious Vendefoul Wolf Linux distribution that uses 217 MB RAM with Devuan as base (no systemd(1) here) and XLibre X11 server along with IceWM wind…
Learn what a unikernel is and how it compares to a Linux container. Build and run your first unikernel inside a playground box.
If you don’t want any of their services, you can turn Siri off in its settings, and disable indexing and search in Spotlight settings. Or you can use mdutil, if you know its limitations.
In keeping with my passion (?) for displaying local news articles in unexpected places , I figured it would be a fun project to try and see what it would take to display current local news on the Nintendo Wii console’s News Channel .
In the 1980s, if you wanted your computer to do floating-point calculations faster, you could buy the Intel 8087 floating-point coprocessor ...
The personal blog of Pig Fang.
A simple, whitespace theme for academics. Based on [*folio](https://github.com/bogoli/-folio) design.
A few years ago, I wrote a blog post on design issues in LLVM IR . Since then, one of these issues has been fixed fully (opaque pointers migration), one has been mostly fixed (constant expression removal), and one is well on the way towards being fixed (ptradd migration).
A post from David Gerard reminded me why I still use Xfce almost everywhere.
A few months ago, users started reporting that Ghostty was consuming absurd amounts of memory, with one user reporting 37 GB after 10 days of uptime. Today, I'm happy to say the fix has been found and merged . This post is an overview of what caused the leak, a look at some of Ghostty's internals, and some brief…
