Robert Elder's Guide to GNU Coreutils
Over the last 18 months, I've taken the time to create 108 short YouTube videos that summarize all of the commands that are found in the Coreutils Package . These videos focus mostly on Coreutils v8.3, but also included are a few commands from v9.0 as well. For each of the blog posts, I've adapted and modified the…

The Emacs Window Management Almanac
Window management in Emacs gets a bad rap. Some of this is deserved, but mostly this is a consequence of combining a very flexible and granular layout system with rather coarse controls.

Why my apps will soon be gone from the Google Play Store
The first real money I ever made from game development was on Android. It was in 2013, when Android was still the underdog compared to the iPhone, and was being touted as a great platform for developers. I’d taken two weeks to build Patchy, a retro arcade game revamped for touch controls, and published it on the…

My Blog Engine Is the Erlang Build Tool
From time to time, people ask me what I use to power my blog, maybe because they like the minimalist form it has. I tell them it’s a bad idea and that I use the Erlang compiler infrastructure for it, and they agree to look elsewhere.

I don't think the cheapest APC Back-UPS units can be monitored except in Windows
Despite otherwise seeming to work correctly, I can't monitor a Back-UPS BX1600MI in Linux without seeing a constant stream of spurious battery detach/reattach and power fail/restore events that last less than 2 seconds each. I've tried multiple computers and multiple UPSes of that model. It doesn't happen in their own…

I get tons of email about Lunar, especially after it became my full time “job” in 2021. A lot of those emails complain about Lunar bugs…
