I was lucky enough to attend to EuroBSDCon 2023 and offered the opportunity to talk about one of my favorite OpenBSD stock daemon: relayd(8). The talk was recorded and made available on the EuroBSDCon YouTube channel. . One may check the EuroBSDCon 2023 program for more material. This post attempts a reboot of the…

This series of articles is a tutorial on the theory and practice of developing language parsers and compilers. Before we are finished, we will have covered every aspect of compiler construction, designed a new programming language, and built a working compiler.
Tutorials and articles of Inigo Quilez on computer graphics, fractals, math, art, demoscene, shaders and more.
I like production gear. Audio, video and .. miscellaneous. I like things that seem like they'll make me oh-so-very productive. I'm a sucker prosumer as a hobby. Let's talk about Elgato, Elixir and why I never actually get anything done. This is unfortunately not sponsored by a prosumer brand, or anyone, that'd have…
GPT-4 will change the world.
A few of my previous blog posts have been about quirks in the UK postal address system. As a result of these posts being moderately popular, people have contacted me to tell me about other such quirks. This pleases me greatly – I like quirks.
First part of a story on how I’ve built 25 Gbps router for home use.
I don't trust Signal because it pretends to be things which it provably isn't and forces use of their controlled the network. This means that if Signal wanted to, they could intercept messages. In this article I show receipts, that while each individual issue is not back-breaking: casts huge doubts to me on if i…
I've been contacted a few times recently about the sharp decline in descriptive images on the events listings.
“The computer has long been a solution looking for problems—the ultimate technological fix which insulates us from having to look at problems.” – Joseph Weizenbaum (1983) Trying to kee…

The embarrassing investor meltdown surrounding Silicon Valley Bank should drive us to consider new models.
In my last blog post I discussed how a small solar project - to power this blog on a Raspberry Pi - escalated into a full-blown off-grid solar setup, large enough to power the computer I use at the moment to write this update 1 . In this update, I want to discuss my battery upgrade.
In the distant nethermists of time, documents once briefly ruled the earth (or at least Mac OS), and to that end I managed to find a verrr...
Two U.S. men have been charged with hacking into a U.S. Drug Enforcement Agency (DEA) online portal that taps into 16 different federal law enforcement databases. Both are alleged to be part of a larger criminal organization that specializes in using fake emergency data requests from compromised police and government…
A critical security vulnerability in Gumroad's API allowed anyone to generate unauthorized license keys for paid products without making a purchase.
There is a ten-foot long alcove in our lower-level hallway — we call it the gallery . This is the one place in our house I can hang whatever I want (i.e., my own art) and switch it out whenever I want. To facilitate this, I installed a hanging system — basically a slotted rail mounted near the ceiling, with sliding…
Once upon a time, there were many music composition software packages, mostly written in Common LISP. To name a few I know, Common Music, Symbolic Composer (not related to the Symbolics Lisp Machine). Common Music is still available in source code but I doubt if anyone is still able to setup that. Symbolic Composer…
From reconfiguring the system to reconfiguring the user.
A number of years ago, I joined a Master’s swim team. I was doing triathlons at the time, and the swim was my weakest leg. The team I joined divided the pool into four lanes: A (fastest swimmers), B (next fastest), C (next fastest) and D (slowest.) Workouts were organized accordingly; faster swimmers were assigned…
podman provides an integrated auto-update mechanism, which I recently applied to all of my containers running on feldspaten. The mechanism is nice, but at first appears a bit counter-intuitive. In this post ’m trying to explain how you can use the mechanism and what to watch out for. I’ll start with the trap I think…

Motivation by itself gives us the willingness to do something, but nothing more. Once we make a start, the game changes and it becomes about knowing how to make progress.
By making a minor concession EU governments hope to find a majority next week to approve the controversial „chat control“ bill. According to the proposed child sexual abuse regulation (CSAR), providers of messengers, e-mail and chat services would be forced to automatically search all private messag
Binary search is a workhorse of competitive programming. There are occasional easy problems where binary search is the solution in and of itself; more often, it’s used as a primitive building block…
