Let's build a query engine from scratch. In about 100 lines of Javascript, we'll support joins, indexes, and find our answer for Arnold!
Wikipedia cites a few different sources on what “Unix Philosophy” is. Peter Salus summarizes it as:
The other day I was reading about the development of personal computers and the desktop GUI, and I was thinking about how comfortable we all have become with the analogy of the “desktop” for our personal computers. We place files in folders and keep them on our desktops. There’s a lot of physical action going on…
Emacs's buffers are so much more than their name implies. They're not just a vessel for you to read or write from. Buffers in Emacs host network processes, shells, and transient data. They're also a key part to understanding why Elisp is designed the way it is.
a bare minimum introduction to modern program synthesis
Java is one of the most widely taught programming languages in the world. Tens of thousands of educators find that the imperative core of the language combined with a straightforward standard library is a foundation that students can comfortably learn on. Choosing Java gives educators many degrees of freedom: they can…
From automating builds and releases to taking care of large-scale regression testing, here are a few ways we use GitHub Actions to build GitHub.
Trying out the Rust programming ecosystem as a 10+ years Python developer. How to do common programming tasks and how the tooling looks like.
There are some books which make you feel smarter just by having them on your shelf. This is one of them! I would consider it essential for anyone working with code - whether a wide-eyed newbie or grizzled veteran. How do human brains understand code? What neurological quirks do we all have? Which common mistakes can…
What is Differentiable Programming, and how is it different from Deep Learning? Check out this introduction to learn everything you need to know!
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…
SQL is a language to handle data in databases. However, it has limitations and you might need to parse SQL to get around them.
Over the last two years, Bluetooth® audio support has steadily grown in PipeWire. Here's a look at where things stand.
sysctl is a simple and great tool for modifying the kernel parameters. It does its job very well by providing an easy-to-use interface for /proc/sys. It is maintained as a part of procps toolkit for years and it can easily be considered a legacy tool today. So why not push it to its limits and turn it into a more…

An advanced beginner's take on WebAssembly.
In this post, we will explore how to build a high-performance database buffer pool in Zig using io_uring's new fixed-buffer mode.
Native lets us build an app that feels right at home on macOS, rather than reflecting the average of every platform and feeling right on none of them. There are a lot of cross-platform approaches out there that attempt to feel native, but they don't.
11 years ago to the day, I was at a tech conference. It was 3 year after the iPhone had launched its app SDK. Those of us who had been in the mobile game a while had already spent years developing apps for Symbian, BlackBerry, Windows CE, and at least a dozen other OSes which I've since scrubbed from my memory. But…
I'm normally a fan of the rigidity within the Go toolchain
