Using the most unhinged AVX-512 instruction to make fastest phrase search algo
Disclaimers before we start For those who don’t want to read/don’t care that much, here are the results. I hope after seeing them you are compelled to read. TL;DR: I wrote a super fast phrase search algorithm using AVX-512 and achieved wins up to 1600x the performance of Meilisearch. The source code can be found here…

When did people favor composition over inheritance?
The phrase "favor composition over inheritance" has become one of those thought-terminating cliches in software design, and I always like to take a deeper look at those to understand where they come from and what ideas we're missing if we just take the phrase at face value without engaging with the discussion that led…

FAWK: LLMs can write a language interpreter
After reading the book The AWK Programming Language (recommended!), I was planning to try AWK out on this year’s Advent of Code. Having some time off from work this week, I tried to implement one of the problems in it to get some practice, set up my tooling, see how hard AWK would be, and… I found I’m FP-pilled.

Ruby and Its Neighbors: Smalltalk
Smalltalk was the second major influence on Ruby's design. A different kind of influence, since almost nothing of Smalltalk's syntax made into Ruby. But many of the details of how objects work are directly inspired by Smalltalk, including the idea that every piece of data is part of the object system.

Window Activation
You click a link in your chat app, your browser with a hundred tabs comes to the front and opens that page. How hard can it be? Well, you probably know by now that Wayland, unlike X, doesn’t let one application force its idiot wishes on everyone else. In order for an application to bring its window to the front, it…

Making TRAMP faster
I recently changed jobs and found myself in a position where I would need to do a lot of work on remote machines. Since I am Emacs user, the most common way to do this is using TRAMP (Transparent Remote access, Multiple Protcol). TRAMP is an Emacs package that let’s you treat a remote host like a local system, similar…

The Algebra of Loans in Rust
The heart of Rust borrow-checking is this: when a borrow is taken, and until it expires, access to the borrowed place is restricted. For example you may not read from a place while it is mutably borrowed.

The Mythical IO-Bound Rails App
When the topic of Rails performance comes up, it is commonplace to hear that the database is the bottleneck, so Rails applications are IO-bound anyway, hence Ruby performance doesn’t matter that much, and all you need is a healthy dose of concurrency to make your service scale. But how true is this in general?

Building the Rust Compiler with GCC
If you know one thing about me, it is that I love working on the Rust compiler. Some people kayak, travel or play guitar - and I stare at assembly, trying to figure out what I broke.
