The costs of microservices (2020)
An application typically starts its life as a monolith. Take a modern backend of a single-page Javascript application, for example - it starts out as a single stateless web service that exposes a RESTful HTTP API and uses a relational database as a backing store. The service is composed of a number of components, or…

Everything I've learned building the fastest Arm desktop
This is the fastest Arm desktop in the world, yes, even faster than the M2 Ultra Mac Pro. And today, I made it even faster. I upgraded everything: Faster RAM, 128 core CPU, 40 series GPU, I did it all, and we'll see how much we can obliterate the M2 Mac Pro. 128 cores—that's five times more cores, I'm also going to…

Unpacking Elixir: Observability
Elixir supports the usual supects of observability. Open Telemetry (OTel), log handlers, capturing metrics. And it does it well. This post will mostly focus on the observability you have on the BEAM that is either incredibly rare to see elsewhere or possibly entirely unique.

Not knowing the /proc file system
Overview Edit: this post was discussed on hacker news Some of the comments contained valuable reviews of the C code listed below. I’ve appended some edits after the original listing. I’ve been working quite with files and file systems on Linux recently. Mostly from the vantage point of either a shell or a python…

NVMe SSD boot with the Raspberry Pi 5
In my video about the Raspberry Pi 5, I mentioned the new external PCIe port makes it possible to boot the standard Pi 5 model B directly off NVMe storage—an option which is much faster and more reliable than standard microSD storage (even with industrial-rated cards!). Enabling NVMe boot is pretty easy, you add a…

Learn Wayland by writing a GUI from scratch
Wayland is all the rage those days. Distributions left and right switch to it, many readers of my previous article on writing a X11 GUI from scratch in x86_64 assembly asked for a follow-up article about Wayland, and I now run Wayland on my desktop. So here we go, let's write a (very simple) GUI program with Wayland…
