What’s the best lossless image format?
In a blog post last year, I took a look at lossy image formats and how they stack up. This time, I thought it might be interesting to do a comparison of lossless image formats.

Trivia About Rust Types
Preface (by Jimmy Hartzell) I am a huge fan of Jon Gjengset’s Rust for Rustaceans, an excellent book to bridge the gap between beginner Rust programming skills and becoming a fully-functional member of the Rust community. He’s famous for his YouTube channel as well; I’ve heard good things about it (watching video…

Why Emacs has buffers
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.

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…

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. It sounds like a smug buzzword or like a gimmick from an academic toy language. Lisp programmers have…

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…

Async Rust doesn't have to be hard
An article titled Rust Is Hard, Or: The Misery of Mainstream Programming came out today and it's getting a lot of attention. I have a feeling that it's viewed in a wrong context, so I'd like to comment on the issue raised there.

Rust Is Hard, Or: The Misery of Mainstream Programming
When you use Rust, it is sometimes outright preposterous how much knowledge of language, and how much of programming ingenuity and curiosity you need in order to accomplish the most trivial things. When you feel particularly desperate, you go to rust/issues and search for a solution for your problem. Suddenly, you…

High-Throughput, Formal-Methods-Assisted Fuzzing for LLVM
Mutation-based fuzzing is based on the idea that new, bug-triggering inputs can often be created by randomly modifying existing, non-bug-triggering inputs. For example, if we wanted to find bugs in a PDF reader, we could grab a bunch of PDF files off the web, mutate them by flipping a few bits or something, and feed…

Programming in the Apocalypse

A vision of a multi-threaded Emacs
The Threading library Starting in Emacs 26 some very ambitious changes were added. Basic thread support was enabled, laying the groundwork for a future concurrent emacs. The docs layout this possibility: Emacs Lisp provides a limited form of concurrency, called threads. All the threads in a given instance of Emacs…

Code quality only matters in context (2019)
I used to obsess about code quality earlier in my career. My experience indicates that I'm in good company here; a lot of us developers spend so much time growing our programming skills, and that kind of drive comes from intrinsic motivation. We care about what we do, and we want to do it well.
