Evolution of tree data structures for indexing
I have to admit, my research blog posts are getting longer and longer. From one side I find it genuinely encouraging, because if one gets so much information just by scratching the topic, imagine what’s hidden beneath the surface! One university professor once said “what could be interesting in databases?”, and it…

Subclassing in Python Redux
The conflict between subclassing and composition is as old as object-oriented programming. The latest crop of languages like Go or Rust prove that you don’t need subclassing to successfully write code. But what’s a pragmatic approach to subclassing in Python, specifically?

Documents ≠ Programs
I've recently become active again on twtxt.net , the platform that puts the "social" in "anti-social social media". There is a lot of intelligent discussion to be had there, and for the past couple days a discussion has been going on about technology buzzwords and, later, unnecessary complexity on websites. I was…

Co-working with friends over video in virtual gather.town office
Starting March 2021, I’ve been spending the majority of my working time co-working with my friends over video in my virtual gather.town office. The sessions are usually pre-scheduled, last 2-16 hours, and we do brief check-ins every 30 minutes. Most people I co-worked with told me that they really enjoyed the…

Floor, Ceiling, Bracket
The notation [x] reigned for nearly two centuries before being replaced by ⌊x⌋. Why the latter is much better and what else we might learn from its inventor.

Rust: Enums to Wrap Multiple Errors
This is a follow-up to Error handling in Rust from a couple of days ago. The moment we want to use error propagation for different error types, we have to rely on trait objects with Box<dyn Error>, which means we defer a lot of information from compile-time to runtime, for the sake of convenient error handling.

Riding the Writing Wave
“Writing is its own reward.” – Henry Miller Writing doesn’t just communicate ideas; it generates new ones. Writing forces you to think. It’s nature’s way of telling you how sloppy your thinking is. The ultimate test of how well you understand something is how clearly you can explain it in writing — clear writers are

Allocgate: Restructuring how allocators work in Zig
Version 0.9 of the Zig programming language is planned to release in about a week. One of the major changes coming in this release is a restructuring of how allocators work, which has been termed Allocgate . This is a breaking change to the Allocator API provided by the standard library, so pretty much any code that…

What's good about offset pagination; designing parallel cursor-based web APIs
Offset pagination gets a bad rap because it’s backend inefficient, but it’s actually a nice feature from a consumer’s perspective. How to bring those advantages to cursor-based APIs.

; Echo “Shell Injection”
This is an introductory article about shell injection, a security vulnerability allowing an attacker to execute arbitrary code on the user's machine. This is a well-studied problem, and there are simple and efficient solutions to it. It's relatively easy to design library API in such a way as to shield the application…

The Secret History of ATAPI
The other day I asked myself a seemingly trivial question: What was the first ATAPI CD-ROM drive and when was it available? Given that ATAPI was a major technology which instantly obsoleted all proprietary CD-ROM interfaces and made SCSI much less desirable, one might expect that there would have been some press…

When can glibc be built with Clang?
Updated in 2026: glibc 2.43 added experimental support for building with Clang. In September 2021, I wrote "So, dear glibc, will you be happy with my sending Clang patches?" in Build glibc with LLD 13. We have come to a turning point. In Linux Plumbers Conference 2021, at the glibc Birds of a Feather session, I asked…
