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…
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.
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? Fields separated by commas and rows separated by newline. Easy right? You can write the code yourself in just a few lines.
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…

On the 1st of January, 1998, Bjarne Stroustrup gave an interview to the IEEE’s ‘Computer’ magazine..
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…
SQL is a language to handle data in databases. However, it has limitations and you might need to parse SQL to get around them.
PHP is a popular general-purpose scripting language that powers everything from your blog to the most popular websites in the world.
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...
How to Use Python in C
Over the last two years, Bluetooth® audio support has steadily grown in PipeWire. Here's a look at where things stand.
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.
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…
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.
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.

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…
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.
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…
