How I blog with Obsidian, Hugo, GitHub, and Cloudflare
I’ve been using Obsidian for all my writing lately, and it’s been a game changer. The local-first model means everything lives as plain text on my machine, and with the Minimal theme, the interface stays clean and distraction-free. My vault lives in iCloud (Dropbox or Google Drive work too), so notes sync seamlessly…

Pixel is a unit of length and area
When measuring the size of a two-dimensional digital picture, the unit pixel is used in a weird overloaded way. Sometimes, it is used as a unit of linear length. For example, each frame of an animation is 1920 pixels wide and 1080 pixels tall. The Cascading Style Sheets (CSS) web standard has px as a unit of length…

Algebraic Semantics for Machine Knitting
As programming languages researchers, we’re entitled to a certain level of mathematical rigor behind the languages we write and analyze. Programming languages have semantics , which are definitions of what statements in the language mean. We can use those semantics to do all sorts of useful things, like error…

Tabular Programming: A New Paradigm for Expressive Computing
I've been exploring the m8 Dirtywave tracker for a few months now, and it's been a fascinating experience. If you're not familiar with it, the m8 is a portable music sequencer built on the Teensy platform that combines a minimal 8-button interface with a powerful tabular workflow. What makes it special isn't just its…

Layered Design in Go
This post will describe how I design my programs in Go. I needed this for work, and while I searched for a link, nothing quite fits my coding practices out there. The word “Layered” can pull up some fairly close descriptions, but I want to lay out what I do.

15,000 lines of verified cryptography now in Python
In November 2022, I opened issue 99108 on Python’s GitHub repository, arguing that after a recent CVE in its implementation of SHA3, Python should embrace verified code for all of its hash-related infrastructure.
