AI slows down open source developers. Peter Naur can teach us why
Metr recently published a paper about the impact AI tools have on open-source developer productivity[^1]. They show that when open source developers working in codebases that they are deeply familiar with use AI tools to complete a task, then they take longer to complete that task compared to other tasks where they…

Minimal PDF
Most PDF files do not look readable in a text editor. Compression, encryption, and embedded images are largely to blame. After removing these three components, one can more easily see that PDF is a human-readable document description language.

Let's Build a Compiler
Compilers, interpreters, runtimes, and the like can sometimes feel vaguely magical. They take your code, perform complex transformations that you only partially understand, and spit out an executable binary. Clearly, the inner workings of such a beast must contain arcane secrets, not meant for the minds of mortals.

Why I'm Not a React Native Developer
Many people are currently assessing React Native as a platform to develop their next mobile app on. This is no trivial matter. Switching your software development platform involves a high setup cost and will profoundly impact your daily programming workflow. It is also one of the costliest decisions to reverse after…

Consider SQLite
If you were creating a web app from scratch today, what database would you use? Probably the most frequent answer I see to this is Postgres, although there are a wide range of common answers: MySQL, MariaDB, Microsoft SQL Server, MongoDB, etc. Today I want you to consider: what if SQLite would do just fine?

The Rust Platform
A programming language is much more than its compiler and standard library. It’s a community. Tools. Documentation. An ecosystem. All of these elements affect how a language feels, its productivity, and its applicability.

A career-ending mistake
As software engineers, we're constantly making detailed, elaborate plans for computers to execute. Isn't it weird that we rarely give a moment's thought to the program for our own careers?

Why Puppet, Chef, Ansible aren't good enough
This particular blog post was sitting on my mind for a long time. I don’t want to start a flame war, but at the same time I also don’t wish for Linux community to build and grow upon ad-hoc solutions that we’ve accumulated over the last 30 years to the packaging and deployment problems. History of Linux automation…

Backdooring Rust crates for fun and profit
Supply chains attacks are all the rage these days, whether to deliver RATs, cryptocurrencies miners, or credential stealers. In Rust, packages are called crates and are (most of the time) hosted on a central repository: https://crates.io for better discoverability. We are going to study 8 techniques to achieve Remote…
