Dijkstra's Algorithm
I was at SCNA the other day, and someone approached me about TDD and Dijkstra’s algorithm. He wondered if you could find a sequence of tests that would lead you to the algorithm. This sounded like a fun little exercise, so I decided to give it a try here.

Sometimes Kill -9 Isn't Enough
If there’s one thing to know about distributed systems, it’s that they have to be designed with the expectation of failure. It’s also safe to say that most software these days is, in some form, distributed—whether it’s a database, mobile app, or enterprise SaaS. If you have two different processes talking to each…

Solving Programming Puzzles Without Using Your Brain
This post is a write-up of a solution to part of a programming puzzle I did yesterday. It’s a little different than the usual “solution + theory” approach, though: I’m going to talk about the actual steps you’d need to take to get to the solution (i.e. what to google, what intermediate code looks like, etc.). Often…

Counting Clojure Code
For better or worse, we count lines of code. We (hopefully) feel a little dirty when we do it, because it's a flawed metric. But we do it . We do it on large codebases and small code snippets . Even badass hacker David Nolen does it .

Singular Value Decomposition for Programmers

LLVM internals, part 4: attributes and attribute groups
This is the last post I plan to do on parsing LLVM’s bitcode, at least for a while. I’ll keep working on the various libraries that I’ve started under the mollusc umbrella, but they won’t be accompanied by regular posts anymore — I’d like to refocus on writing smaller, less dense (read: lower-pressure) posts for a…

Erlang: A Generalized TCP Server
In my last few articles about Erlang we've covered the basics of network programming with gen_tcp and Erlang/OTP's gen_server, or generic server, module. Let's combine the two.

Everyone has JavaScript, right?
These are by no means all the reasons why your JavaScript might fail to run even when you expected it to. Andy Bell has a great list over at piccalil.li of a handful of very realistic reasons JavaScript won’t be available . Check ’em out, and be prepared.

A critique of package managers
n.b. This is a written version of a dialogue from a YouTube video: 2 Language Creators vs 2 Idiots | The StandupPackage managers (for programming languages) are evil.11 The term “evil” is being used partially hyperbolic to make a point.To start, I need to make a few distinctions between concepts a lot of programmers…

Life Before Unicode
Unicode definitely added a lot of complexity to string handling, and people who use languages with ASCII alphabets exclusively may think it's unjustified. However, I'm a non-ASCII language speaker who's old enough to remember the alternatives, and the alternatives are far worse than the complexity of Unicode.

Making sense of React Server Components
This year, the React team unveiled something they've been quietly researching for years: an official way to run React components exclusively on the server. This is a significant paradigm shift, and it's caused a whole lot of confusion in the React community. In this tutorial, we'll explore this new world, and build an…

Maybe We Should Stop Creating Inscrutable CLIs
In the original Unix tradition, command-line options are single letters preceded by a single hyphen…The original Unix style evolved on slow ASR-33 teletypes that made terseness a virtue; thus the single-letter options.

Friendship ended with the garbage collector
It's been a while since the last update about my work on the Inko programming language . Not because there hasn't been any progress, but because I've been busy making changes. A lot of changes.
