The Intel 8088 processor's instruction prefetch circuitry: a look inside
In 1979, Intel introduced the 8088 microprocessor, a variant of the 16-bit 8086 processor. IBM's decision to use the 8088 processor in the I...

Fundamentals of Object Storage in Elixir
I did a livestream where I talked about Object Storage. The how and why. The Bad Old Days. And also the neat and interesting stuff just beyond the basics. I figured I'd cover that in text as well.

Post-quantum cryptography is too damn big
Large-scale quantum computers are capable of breaking all of the common forms of asymmetric cryptography used on the Internet today. Luckily, they don’t exist yet. The Internet-wide transition to post-quantum cryptography began in 2022 when NIST announced their final candidates for key exchange and signatures in the…

Algorithmic Mathematical Art (2004)
In the early 1990s, they were merely visualization aids in the study of mathematics. Gradually, the complexity and artistry of the images becomes an end itself.

DuckDB as the New jq
Recently, I’ve been interested in the DuckDB project (like a SQLite geared towards data applications). And one of the amazing features is that it has many data importers included without requiring extra dependencies. This means it can natively read and parse JSON as a database table, among many other formats.

The baffling intelligence of a single cell: The story of E. coli chemotaxis
I want to tell the story of a beautiful phenomenon in biology. In some sense it’s the prototype of much of the activity of life. The phenomenon is the way in which an individual cell of E. coli forages for nutrients. This process, known as “chemotaxis”—the “chemo-” for chemical and the “taxis” from the Greek τάξις…

Tiny Undervalued Hardware Companions
After playing/working with computers for more then 25 years I started to appreciate small but handy valuable stuff – like adapters or handlers or … yeah – all kind of stuff. With …

Array Languages: R vs. APL (2023)
I’ve been learning at least one new programming language a month through Exercism which has been really fun and interesting. I frequently say that “every language you learn teaches you something about all the others you know” and with nearly a dozen under my belt so far I’m starting to worry about the combinatorics of…

The C++ Killers (Not You, Rust)
All the “C++ killers”, even these which I wholeheartedly love and respect like Rust, Julia, and D, help you write more features with fewer bugs, but they don't much help when you need to squeeze the very last FLOPS from the hardware you rent. As such, they don’t have a competitive advantage over C++. Or, for that…

Focus by Automation
I’ve invested leisure time to save time when I’m working hard, not to save keystrokes but to save mental energy for the project at hand.

Why does an extraneous build step make my Zig app 10x faster?
For the past few months, I’ve been curious about two technologies: the Zig programming language and Ethereum cryptocurrency. To learn more about both, I’ve been using Zig to write a bytecode interpreter for the Ethereum Virtual Machine. Zig is a great language for performance optimization, as it gives you fine-grained…

Regex character "$" doesn't mean "end-of-string"
This article is about a bit of surprising behavior I recently discovered using Python's regex module (re) while developing SBOM tooling for CPython. Folks who've worked with regular expressions be...

Let's create a Tree-sitter grammar
One of my favorite features in Neovim is the Tree-sitter integration. It allows for fast syntax highlighting that works well even in an error state (often the case when you’re editing code), and it has additional semantics (you can differentiate between function parameters and local variables).
