This is a really neat pattern. Start your Python script like this: #!/usr/bin/env -S uv run # /// script # requires-python = ">=3.12" # dependencies = [ # "flask==3.*", # …

Using gRPC for (local) inter-process communication (2021)
Using a full-featured RPC framework for IPC seems like overkill when the processes run on the same machine. However, if your project anyway exposes RPCs for public APIs or would benefit from a schema-based serialisation layer it makes sense to use only one tool that combines these—also for IPC. Microservices for…

Lush: My favorite small programming language
I meant to write about this when I started my blog in 2009. Eventually Lush kind of faded out of my consciousness, as it was a lot easier to get work doing stuff in R or Matlab or whatever. The guy…

Using Erlang hot code updates
One of the Erlang ecosystem's spiciest nerd snipes are hot code updates. Because it can do it. In ways that almost no other runtime can. I use Elixir which builds on Erlang and has the same capabilities.

Dear sir, you have built a compiler (2022)
I am afraid to inform you that you have built a compiler. I know you wanted a “simple prototype” that would just add that one feature to your programming model. You said that “SSA is an overkill” and “it’s just way too much infrastructure to maintain for a simple task” and yet, six months later, you have pile of…

OCaml Syntax Sucks (2016)
OCaml's let … = … in … is very confusing. When nested, you can't tell how it's nested.

How to Build a Chess Engine and Fail
A Chess-AI is something every programmer should build at least once and [Sebastian Lague’s](https://www.youtube.com/@SebastianLague) [competition](https://www.youtube.com/watch?v=iScy18pVR58) was the perfect opportunity for me to do so. Constrained to 1024 tokens I wanted to implement an evaluation function similar to…

A BBC navigation bar component broke depending on the external monitor
Recently, my team and I fixed an absolutely bizarre bug that only one person in the team could reproduce. And to make it even weirder, she was only able to reproduce the issue when using her work laptop at home; it worked fine with the same laptop in the office.

Against Best Practices
I have come to believe that by and large “best practices” are doing more harm than good. Not necessarily because they’re bad advice as such, but because they’re mostly pounded by either 1) various types of zealots, idiots, and assholes who abuse these kind of “best practices” as an argument from authority, or 2)…

The myth that you can’t build interactive web apps except as single page app
Tony Alaribe challenges common myths about multi-page applications (MPAs) and explores how modern browser technologies can enable fast, interactive, and offline-capable web applications without relying on single-page application (SPA) frameworks. Alaribe discusses advancements in service workers, caching, and…

Nash equilibria in Ballmer's binary-search interview game
Yesterday John Graham-Cumming posted about “Steve Ballmer’s incorrect binary search interview question,” and in the Hacker News discussion, among the predictable “interview culture is flawed!!” complaints, there was some discussion of whether binary search was even the right way to solve Ballmer’s puzzle. Here’s a…

Constraints in Go
Freedom is nothing without constraints, and Go’s generics gives us a powerful way to build polymorphic types and functions constrained by type sets . Let’s geek out.

Stop making me memorize the borrow checker
I started learning Rust about 3 or 4 years ago. I am now knee-deep in several very complex Rust projects that keep slamming into the limitations of the Rust compiler. One of the most common and obnoxious problems is hitting a situation the borrow-checker can’t deal with and realizing that I need to completely…

SICP: The only computer science book worth reading twice? (2010)
I was talking to one of my students earlier, and lent him a book to read over summer. It was only after he’d left that I realised that — for me at any rate — the book I’d given him is probably the most seminal work in the whole of computer science, and certainly the book that’s most influenced my career and research…

Optimizers: The Low-Key MVP
The query optimizer is an important part of any analytical database system as it provides considerable performance improvements compared to hand-optimized queries, even as the state of your data changes.
