Parser Combinators Beat Regexes
Someone online was solving Advent of Code problems, and had a question about last years’ day 3 . They had a working solution using regular expressions (regexes) on String values, but they wanted to use ByteString values instead for performance reasons. They were surprised, however, that there seems to be a lack of…

Baking the Y Combinator from Scratch
EDIT: Part 2 is up! It's a pedagogical pet peeve of mine when technical concepts are simply listed in their fully developed state, with little in the way of motivation, derivation, or historical context. This, I think, is like publishing a cookbook filled with beautiful pictures of cakes, but

LLMs understand nullability
The last five years have shown us that large language models, like ChatGPT, Claude, and DeepSeek, can write code in many domains, to huge excitement: many claim to be using these models to write entire web servers and apps from scratch. These tools have opened up programming to a whole new class of people who consider…

Writing C for Curl
It is a somewhat common question to me: how do we write C in curl to make it safe and secure for billions of installations? Some precautions we take and decisions we make. There is no silver bullet, just guidelines. As I think you can see for yourself below they are also neither strange nor … Continue reading Writing…

Nix Derivations, Without Guessing
I went on a little low-level Nix adventure yesterday and early this morning because of this excellent blog post. In it, Farid builds up the simplest possible Nix derivation—making a file that has the contents “hello world”. Here’s what I like about it:

Baby Steps into Genetic Programming
While my final ranking in the Google AI Contest was disappointing ( 280th ), it was a very educational experience and was totally offset by Gábor Melis' dominating win using Common Lisp as well.

Pitfalls of Safe Rust
When people say Rust is a “safe language”, they often mean memory safety. And while memory safety is a great start, it’s far from all it takes to build robust applications. Memory safety is necessary but not sufficient for overall reliability. In thi…

Dijkstra On the foolishness of "natural language programming"
Since the early days of automatic computing we have had people that have felt it as a shortcoming that programming required the care and accuracy that is characteristic for the use of any formal symbolism. They blamed the mechanical slave for its strict obedience with which it carried out its given instructions, even…
