Speeding up VSCode extensions in 2022
I was curious to know if the functionality of VSCode can catch up with the native speed of some editors, such as Sublime. That led me to seek out where some bottlenecks may be and where time is being spent. In this post I look at both the internals and extensions.

All I want for Christmas is these seven TypeScript improvements
It's Christmastime and I've been happily working through this year's Advent of Code in Deno (look forward to a blog post in the new year).

Markdown, Asciidoc, or reStructuredText – a tale of docs-as-code
Who writes the developer documentation for your product? During the early days of my tech career, I worked on a database replication product at IBM. My immediate team had developers and testers but not a single technical writer. I can speak for myself when I say that I never bothered to know who keeps writing the…

Visualizing Delaunay Triangulation
Take a look at this: This is a triangulation of a set of random points, such that all the points are connected to one another, all of the faces are triangles, and the edges include the convex hull of the points.

To save C, we must save ABI
After that first Firebrand of an article on Application Binary Interface (ABI) Stability, I’m not sure anyone expected this to be the title of the next one, huh? It seems especially bad,
