A deeper dive into why shell scripts cannot replace a proper CI control plane, drawn from years of building and operating CI systems at scale.
Forking is Cool, or: A Unix Shell in Zig, or: Dave Learns How to Fork - ratfactor
In this article, I make a real, working interactive shell written in Zig. Though essentially a toy, it demonstrates the incredible elegance of the fork() system call and is an example of what can be done with absolutely no runtime memory allocations.
Improving My Hardware Workflow With CI and Nix
One thing you might notice if you read my blog is that I do a lot of hardware projects. Generally, these include a board, some software, and possibly some extraneous components (like CAD design, such as a case).

A Designer’s Guide to the Terminal
You can learn how to use the terminal in a fairly short amount of time. You don’t need a C.S. degree. You don’t need to know how to hack any mainframes.
the world hasn’t figured out yet that you can literally just fix everything with a Nix overlay
There are many things that are uncertain in our industry right now, but one thing I am certain about, and have been for almost 13 years, is that Nix is a terrible programming language. I remember when I first learned it, it felt like pushing shit uphill. The learning cliff
A shell exclamation mark is not for yelling. Be lazy. | Filip Roséen - refp.se
