Another Week with Bad Software
In the midst of my September job hop I headed to Kazan for the weekend. I don't know exactly why — probably because I could. I had a hotel booked via booking.com, but once I arrived there the receptionist told me it was the first time he's heard of my booking, and he told me that they had no more rooms, and he told me…

Organizational Debt
We all know that classic aphorism: Year comes to an end, Rust blog post press send. This is mine. There are lots of cool technical improvements to Rust that I want the project to achieve this year, and a few in particular that I’m definitely going to be putting a lot of time into.

How Clang Compiles a Function
Minor nit: printing the predecessors of a basic block is a feature of the IL printer, not Clang. It is just visualizing information that is implicit in the IR anyway.

Sadly, I must say goodbye to Leaf, my programming language
This is hard to write, or rather, it’s a hard decision to make. After investing many years on Leaf — a programming language, a major life project — I need to take a break from it. It’s no longer fulfilling my goals, and it’s not as fun as it once was. It’s interfering with my […]

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.

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.

There's quite a lot of talk these days about Single Page Applications (SPAs) and the terrific user experience they deliver. This is great, and the SPA architecture is probably a good fit for many apps, but I want to point out two reasons why SPAs are harder to develop and maintain than tr
