We recently passed the one-year anniversary of Hurricane Helene and its devastating impact on Western North Carolina. As a web developer, I am thinking again about my experience with the mobile web on the day after the storm.
When the Compute Module 4 was released (see my CM4 review here), I asked the Pi Foundation engineers when we might be able to boot off NVMe storage, since it was trivially easy to use with the exposed PCIe x1 lane on the CM4 IO Board. The initial response in October 2020 was "we'll see". Luckily, after more people…

A large amount of fantastic open source software originates from “scratching an itch”. Such was the case with Firecracker . In 2014, Amazon launched AWS Lambda as a “serverless” compute platform: Users can provide a function — say, ten lines of Python code — and Lambda provides all of the infrastructure between an…

There’s a javascript emulator for the TI83+, TI84+, and TI84+CSE calculators called jsTIfied, which was written by Christopher Mitchell, founder of the calculator fan site cemetech.net. There’s not a whole lot of reasons to use it over something else if you’ve got a native option available, but if you don’t it’s…
mount semi-structured data (like JSON) as a Unix filesystem
htop is a great tool but lacks good documentation. This article takes a visual and simple approach to explaining htop.
How we used SKIP LOCKED, composite primary keys, and connection visibility to hit our scale targets.
Our CPUs were dying, the bug was temporarily un-fixable, and we had no viable path forward. Here's how we managed to survive.
About a year ago, Hetzner launched the AX162 server line. It offered better price / performance than its predecessor, AX161. We were very excited to adopt it, but we soon encountered serious reliability issues. We observed that the new servers had 16 times higher annual failure rates.
I talked at the first Zig meetup in Milan about Uber's early experience with Zig: a little about how Uber uses Zig and more about my experience of bringing Zig to Uber, from both technical and social aspects.
Was passiert wenn man ein Windows Update durchführt, oder mehrere?.
Traditional Wayland compositors have a monolithic architecture that combines the compositor and window manager into a single program. This has the downside of requiring Wayland window managers to do the significant work of implementing an entire Wayland compositor as well.
Getting ECC memory working on desktop CPUs.

It's time for servers to handle 10 million simultaneous connections, don't you think? After all, computers now have 1000 times the memory as...
It’s no secret that hardware selection is one of the biggest hurdles Qubes users face. Finding a computer that is secure, trustworthy, and compatible is more difficult than it should be. In an effort to address the compatibility aspect of that problem, we introduced the Qubes-certified ...
During some random discussion with my colleague today, I rediscovered an experiment I did quite some years ago: MP3 compression of image data. This is, feed raw 8-bit-per-pixel grayscale image data into an MP3 encoder, let it compress it, and decode the MP3 file again. After some conversion (the decoder will always…
Making sure I don’t forget what I read.
This post is about building an LLM inference engine using C++ and CUDA from scratch without libraries.

Memory safety and sandboxing are two different things. It's reasonable to think of them as orthogonal: you could have memory safety but not be sandboxed, or you could be sandboxed but not memory safe.
Yesterday, one of our customers let us know about significant performance issues they have experienced on Heroku. They raised an important issue and I want
