Strokkur The main attraction at Geysir is Strokkur, a geyser that supposedly erupts about every 10 minutes. While we were there, it seemed to erupt about every 5 minutes! We saw more than half a dozen eruptions, and the height varied a lot. Geysir The namesake of Geysir, this geyser is a stone’s throw from Strokkur, but nowadays is dormant...

Well-ingrained into every Emacs user is the echo area, a one-stop shop to receive any kind of message from the editor, located at the bottom of the frame. Posting messages to this area from elisp couldn't be simpler: (message "Hello world") If we want to get a little fancier, we can propertize the text to add some styling. (message (propertize "hello " 'face '(:foreground "#C3E88D")) (propertize "world" 'face '(:foreground "#FF5370"....

This is part 3 from series “Tiny Great Languages”. Final code is on Github. Part 1: Assembly. Part 2: BASIC. Part 3: Forth/MOUSE. Part 4: Lisp. Part 5: APL/K. Part 6: PL/0. Let’s go Forth. A concatenative language available on early computers, a great example of how small, elegant languages can be both powerful and efficient. I’ve already covered building a proper Forth from the ground up in an earlier post.

We’re going to be writing a BF compiler for a class I’m in. Last night I threw together a little interpreter for the program in about an hour; it doesn’t do input—that should be easy to add—but it’s enough to handle some benchmarks for the language, albeit slowly. You can see my repository on Codeberg for the source code. I needed one function to do two closely related jobs—the logic was identical, but some parameters needed to chan....

In the context of Alejandro Colomar stepping down as a man-pages maintainer :(, I learned from him that it is possible with git to create an email patch set that spans multiple target repositories. Specifically, he pointed to a review thread by Jiri Olsa where this was done, and whose outline takes a similar shape to this (simplified): [PATCH proj v3 0/3] foobar: Add transmogrifier [PATCH proj v3 1/3] foobar: Prepare flux compe....

In the end we won because the open source community started to converge on distributed version control and we were the only ones in the hosting space that truly cared about how developers worked at all. The only ones who questioned it, approached it from first principles, tried to make it better holistically rather than just throwing more features onto something existing in order to sell it. Full story here . A great run-down by Scott C..

In this post, we are going to take a deep dive into pointer tagging, where metadata is encoded into a word-sized pointer. Doing so allows us to keep a compact representation that can be passed around in machine registers. This is very common in implementing dynamic programming languages, but can really be used anywhere that additional runtime information is needed about a pointer. We will look at a handful of different ways these pointers c..

Reply to Improving how I handle secrets in my work notes The nice thing about auth-source is that it has a pluggable backend - it can be used with any password store like OS keyring, password manager, etc. See some backends at https://melpa.org/#/?q=auth-source- and https://github.com/search?q=%22auth-source%22+language%3A%22Emacs+Lisp%22+&type=repositories I use it with the 1password …

Decades ago, I wrote my first interpreter – a Turtle Graphics IDE designed to help kids at my school learn programming. I built it in Pascal, and to this day, I still wonder how I managed to make it work without any formal knowledge of writing interpreters.

One of my two ~10 year old 23" 1080p main displays died recently. So I finally upgraded to two used 27" 1440p displays. These are now the first displays on my desktop that allow adjustments of the backlight from software. So I tried to find out how to go about that. Turns out on laptops both the display backlight intensity and the ambient light sensors are controlled via ACPI, with proper kernel support already available (see eg. the Arc....

So you may have read about our project LARS . As mentioned I didn't have any hardware in the end to finish firmware development. So I slightly updated the circuitry, layed out a new board, had it manufactured in China and assembled at home. This is LARS v2, the second iteration of the same idea. It's basically the same device, just with five additional switches. This allows for some more freedom in the user interface desi....

Packing Matrix-Vector Multiplication in Fully Homomorphic Encryption

In my recent overview of homomorphic encryption, I underemphasized the importance of data layout when working with arithmetic (SIMD-style) homomorphic encryption schemes. In the FHE world, the name given to data layout strategies is called “packing,” because it revolves around putting multiple plaintext data into RLWE ciphertexts in carefully-chosen ways that mesh well with the operations you’d like to perform. By “mesh well” I mean it redu..
