The git history command
Working with lots of changes in parallel on git can be painful. You end up juggling branches and commits, and running scary rebase -i commands that can leave your tree in a half-broken state if you so …

Quadrupling code performance with a "useless" if
So I was optimizing a domain-specific compressor the other day, as one does. One important problem was chunking the input string and optimally choosing the most compact encoding for each chunk (different encodings compress different characters better, so where to split is not immediately obvious). The previous post…

Your code is fast if you're lucky

Good Tools Are Invisible
TL;DR: A good tool is and ought to be invisible—striving to make such tools is the goal of a toolmaker.One habit I see a lot, and have to push back on, is taking a tool's shortcomings and reselling them as a "puzzle game" which is "fun" to solve.I don't want my tools to be "fun". I want my tools to be invisible.Text…

In Emacs, everything looks like a service
A common refrain is that Emacs is an operating system (OS). This isn’t true, but what invites comparison to an OS is its ability to orchestrate applications and utilities above the OS kernel...
