Conditional Git Configuration
Building on the earlier article on automatically transforming Git URLs, I’m back with another article on a (potentially powerful) feature of Git—the ability to conditionally include Git configuration files.

Using Git Offline
Some companies use an isolated network or even the complete lack of a network as a security measure to protect from unauthorized access. Working on these systems can be a struggle but it is still possible, and perhaps even more important, to use a proper version control tool like Git.

Golden Rules of Interface Design (2013)
I have often been asked to distill the vast corpus of user interface design into a few key principles. While I was reluctant to do this, it turned out to be a good exercise to write “Golden Rules,” that are applicable in most interactive systems.

Things engineers believe about Web development

I don’t really like doing posts like this—I’d much rather share some innocuous learnings or tips but it turns out I have opinions too 😓 Sorry! 2024-02-21: I’ve added a few reflections at the end…

SIMD in Pure Python
First of all, this article is an exercise in recreational "because I can" programming. If you just want to make your Python code go fast, this is perhaps not the article for you. And perhaps Python is not the language you want, either!

Emacs commands I got by with for years
As far as I know, the next meeting of EmacsATX, the Austin Emacs Meetup group , has a planned topic: Org mode .
