Turning Sublime Text into a Lightweight Python IDE
A solid text editor is a developer’s best friend. You use it constantly and it becomes like a second pair of hands. The keyboard commands you use daily become so engrained in your muscle memory that you stop thinking about them entirely.

Software architecture is failing
I doubt there has ever been a time when software architecture was seen as a raging success. The “three-tier architecture” of the web has held up extremely well and is an excellent place for many people to start. The “12 Factor App” approach has encouraged developers to adopt practices that make deployment and scaling…

The vgo proposal is accepted. Now what?
Last week, the proposal review committee accepted the “vgo approach” elaborated on this blog in February and then summarized as proposal #24301 . There has been some confusion about exactly what that means and what happens next.

The Sideprocalypse
You can't open a feed today without having AI boosters fling word salad like "agentic engineering" or "openclaw" into your beautiful but disapproving face. I'm terrible at predicting the future—you should ask me about selling NVIDIA stock in early 2022 some time—but one thing seems…

So You Want to Write Your Own CSV code
So You Want To Write Your Own CSV code? Fields separated by commas and rows separated by newline. Easy right? You can write the code yourself in just a few lines.

Why Can't Database Tables Index Themselves? (2006)
Here’s a thought question for today: why can’t database tables index themselves? Obviously, indexes are a central concept to databases and database performance. But horror tales still abound of naïve developers who “forget” to index their tables, and encounter massive performance and scalability problems down the road…

0xF Rules
I have been writing articles on this website for twelve years. If you were to look at the early versions , you would think it is a fresh-out-of-school project with icons drawn in Microsoft Paint. And that is exactly what it was. The site started in a world before smartphones and tablets at a time where Apple products…

Something about functions in Bash (2017)
Here's something you didn't know about bash functions. Usually when you write a function you do this: function name () { ... } Right? I know you do, because that's how everyone writes functions. Well, here's the thing. In bash { ... } doesn't mean "function's body" or "function's scope" as in JavaScript or C. It's...

Approximating sum types in Python with Pydantic
TL;DR: You can use Pydantic’s support for tagged unions to approximate sum types in Python; go right to Sum types in Python (and onwards) to see how it’s done.

Fast Fourier transform in x86 assembly
I have a simple fast Fourier transform implementation on the page Free small FFT in multiple languages , whose asymptotic time complexity is the optimal Θ( n log n ). I wanted to know how much additional speed-up could be obtained by reorganizing memory access patterns and using SIMD vector arithmetic instructions…

Covers as a way of learning music and code
When you're just getting started with music, you have so many skills to learn. You have to be able to play your instrument and express yourself through it. You need to know the style you're playing, and its idioms and conventions. You may want to record your music, and need all the skills that come along with it.

Being Sneaky in C
I entered the 2014 Underhanded C Contest last year. Didn't win, but hey-ho what can you do. Still, I thought I'd post my entry and a write-up of it, in case anyone found it interesting.

Moving Java Forward Faster
For over twenty years the Java SE Platform and the JDK have evolved in large, irregular, and somewhat unpredictable steps. Each feature release has been driven by one or a few significant features, and so the schedule of each release has been adjusted as needed — sometimes more than once! — in order to accommodate the…

Porting a NES Emulator from Go to Nim
Let me get this straight. We have an emulator for 1985 hardware that was written in a pretty new language (Go), ported to a language that isn’t even 1.0 (Nim), compiled to C, then compiled to JavaScript? And the damn thing actually works? That’s kind of amazing.

Dark corners of Unicode
I’m assuming, if you are on the Internet and reading kind of a nerdy blog, that you know what Unicode is. At the very least, you have a very general understanding of it — maybe “it’s what gives us emoji”. That’s about as far as most people’s understanding extends, in my experience, even among programmers. And that’s a…

GNU GCC does not round floating-point divisions to the nearest value
I know that floating-point arithmetic is a bit crazy on modern computers. For example, floating-point numbers are not associative: 0.1+(0.2+0.3) == 0.599999999999999978 (0.1+0.2)+0.3 == 0.600000000000000089 But, at least, this is fairly consistent in my experience. You should simply not assume fancy properties like…
