Welcome!

My repository of things I've learned. Mostly programming related. Part microblog, part knowledge base, part digital garden. If you like this, you might enjoy my blog.

Recent TILs

• November 18, 2024 systemd Set up a basic service

  I use systemd pretty infrequently, so whenever I need to stand up some persistent process on a server I spend a bunch of time looking things up again. Hence: this TIL!

• October 19, 2024 math Check whether an angle is between two other angles

  Weirdly, I've had to do this a lot recently: given an angle, determine whether it's bounded by two other angles. Technically, this is always true — just go the other direction around the circle — but usually I care about going in a particular direction.

• October 2, 2024 git Update all submodules to latest commit on origin

  I use Git submodules in a bunch of projects, and one common task is checking out the latest commit on the origin.

• September 19, 2024 entr Reload a webpage when a file changes

  I store my blog in a git repo of plain Markdown files. It's a pretty spartan setup, which I like — it forces me to keep all my writing extremely portable between website generators.

• March 23, 2024 prosemirror Prevent extra whitespace in NodeViews

  While trying to build a ProseMirror NodeView using a Shoelace dropdown, I kept getting a ton of extra vertical space around the dropdown trigger.

• March 21, 2024 django Conditionally extend a template

  Django supports template inheritance via the extends tag. Often, a template inheritance chain follows all the way up to a "base" template that contains the full markup for a page, from the doctype to the closing HTML tag.

• March 14, 2024 prosemirror Use a Svelte component as a NodeView

  The ProseMirror rich text editor library has a concept called NodeView for rendering custom widgets with a document.

• February 14, 2024 svelte Force reactive state to reevaluate

  In Svelte 5, you declare a reactive variable using the $state rune.

• February 6, 2024 git Ignore all .DS_Store files

  If you use git on a Mac, chances are you've accidentally committed a .DS_Store to a repo. I used to reflexively add .DS_Store to all my .gitignore files to avoid ever repeating that mistake.

• January 28, 2024 logic Send stereo output through specific output channels

  This probably works for many audio interfaces, though in this case I'm using a Quad Cortex. When I have my interface hooked up to Logic Pro, I want to route stereo output to the specific output channels that are connected to my speakers.
