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..

Keyword arguments in Python aren't free. Switching from PyArg_ParseTupleAndKeywords to METH_FASTCALL and manual parsing yields a 35% speedup in function calls.

This is part 1 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. 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..

A couple of months ago, I introduced Ready Player Mode , an Emacs major mode used to peek at media files from my beloved text editor. The goal was simple. Treat opening media files like any other file, that is, open and go. The initial implementation served me well while reviewing lots of tiny audio files I used to practice learning a new language. At this point, I started thinking, could I use ready-player for regular music consumption?....

This is post of appreciation of my Garmin Instinct Solar watch, which has travelled the world with me and been an indispensable tool in many adventures . It has GPS recording, altimeter, thermometer and sunset time, but thanks to the monochrome display, the battery lasts for month (+recharging from the sun), not like your silly "smart" watch :p I also like to use different straps all the time, so that when I look at w..

Note, I’ll use Ruby on Rails 💎 as my example for this post but this can be done in nearly all modern language as SQIDs support most of them . They’re also interoperable, so you can generate in Ruby and decode in another C# service. Why does GraphQL need Global IDs? In GraphQL has the concept of Global Object Identification . Each item in the API has a unique Global ID. If you’re using a fairly normal web development framework, y..

It’s been over 4 years since my first post on this blog. During those 4 years I’ve written over 90 posts, received over 1 million clicks, a dozen legitimate reader e-mails and thousands of spam e-mails. And I love it! I’ve found that writing can be very fulfilling and I encourage you to at least give it a try. This post covers the reasons why I write, how I write and some tips on how you can get started writing one yourself. ....

Go's new Iterators were released on August 13th with Go 1.23 . They're pretty useful. They've had just a minute to marinate. In some parts of the community they've been an unpopular addition, however I don't particularly mind them. The old alternatives seem a little more "Go" to me, but the new iterators are fine. One thing however I am mildly disappointed about is that there isn't just a generic iterable type similar to the gener....
