MVC is dead, it's time to MOVE on (2012)
MVC is a phenomenal idea. You have models, which are nice self-contained bits of state, views which are nice self-contained bits of UI, and controllers which are nice self-contained bits of …

Research software code is likely to remain a tangled mess
Research software (i.e., software written to support research in engineering or the sciences) is usually a tangled mess of spaghetti code that only the author knows how to use. Very occasionally I encounter well organized research software that can be used without having an email conversation with the author (who has…

Bad Emacs defaults
I was working on a new installation where I didn’t have this in place yet and I kept trying to update a shell function, re-sourcing it but it never changed. Turns out it was loading from a backup~ of the same file.

True Scala complexity
Due to the recent php2shell vulnerability , to save time and effort for both users and maintainers alike, and out of an overabundance of caution, all Scripts sites have had PHP (php-cgi) disabled until a patch is available and backported.

The Overengineered Resume with Zola, JSON Resume, Weasyprint, and Nix (2023)
Maintaining a resume is not the most interesting use of time. Naturally, when I needed to bring my own up to date, I decided to spend a great deal more time on it and overengineer the process.

Towards fearless SIMD
SIMD is a powerful performance technique, and is especially valuable in signal and image processing applications. I will be using it very extensively in my synthesizer, and also it’s increasingly used in xi-editor to optimize string comparisons and similar primitives.

Why Does Integer Addition Approximate Float Multiplication?
Here is a rough approximation of float multiplication (source): float rough_float_multiply(float a, float b) { constexpr uint32_t bias = 0x3f76d000; return bit_cast<float>(bit_cast<uint32_…

Idempotency keys for exactly-once processing
In distributed systems, there’s a common understanding that it is not possible to guarantee exactly-once delivery of messages. What is possible though is exactly-once processing. By adding a unique …

Python Idioms in Rust
I’ve been going through a period of programming language wanderlust over the past couple months. Recently, I’ve been quite interested in Rust. Coming from Python, I’ve found a lot of Rust’s language features to be quite powerful.

Goroutines, Nonblocking I/O, and Memory Usage
I am generally a fan of Go's approach to concurrency: writing code with goroutines is a lot easier than writing traditional nonblocking network servers in a language like C or C++. However, while working on a highly concurrent network proxy I came across an interesting realization about how the Go concurrency model…

Performance Tuning for .NET Core
Some of you may know I've been spending whatever time I can scrounge together grinding away at a new serialization library for .NET. Serializers can be complicated beasts. They have to be reliable, flexible, and fast beyond reproach. I won't convince you that serialization libraries have to be quick — in this post…

Compressing a flag to 11 bits
I recently saw an interesting YouTube video by “Physics for the Birds”. The main video is about matrixes, but he used flags to explain some of the operations on matrixes:
