The true cost of linked lists
Linked lists are often overused in introductory algorithmics courses, due to a heavy focus on theorical complexities. Unfortunatly, in practice, computers are complex beasts. They don’t execute instructions sequentially 1 with the same cost 2 . This means that a data structure with faster theorical complexities does…

Plain text, with lines
I like plain text. I also like doodling while I write. Some things are just easier to explain with a picture. But if I need to draw a picture today, I need to stop writing plain text, pick an app, dismiss a couple of dialogs or tours of new features in front of my face, think about all the ways it's acting for its…

What is a programmable programming language? (2019)
When I was still researching this fabled obscure language called Lisp one thing people kept saying about it is that “Lisp is a programmable programming language”, but I could never figure out what they meant by that.

Italian CPU – The Genesys B52 MMX
On this site you can read about thousands of processors models. And every year it is more and more difficult to write about some new (old) processors, since everything has been known for a long time. But there are also exceptions to the rule which we love to find. In 2021, I learned about one unusual processor, the…

I only care about the helpful notifications, not the promotional ones
Here’s a scenario. First, you download an app for a service that has some sort of in-person component, like picking up an order or meeting a driver at the curb. When using that app for the goal, be it that order or that meeting, it’s very helpful to have notifications, since they give you the current status and it can…

I Built a Ruby Parser
Sorry, this post will read like a “dear diary” entry rather than some life-changing HN-worthy guidance. Back in November 2020, almost on a whim I started work on a new parser for the Ruby programming language. It was almost exactly a year after I had started working on my compiler project (I hope to write a longer…

Arc and Mutex in Rust
When writing concurrent Rust you will encounter Arc and Mutex types sooner or later. And although Mutex might already sound familiar as it's a concept known in many languages, chances are you haven't heard about Arc before Rust. What's more, you can't fully understand these concepts without tying them to the ownership…

Solving the housing crisis requires fighting monopolies in construction (2020)
U.S. government concerns about great disparities in housing conditions are at least 100 years old.
