We have a WaterCop system at home from the ancient days before Apple HomeKit and also an old lighting system. The first one has false alarms and we can’t ever tell which sensor actually triggered since they all feed a single sensor into the alarm system. The lighting system has…

One of the cool things that GitHub handles pretty well is changing your company’s organization. For instance, if you have a secret name, say Acme, then you create an organization and your main repo could be in git@github.com:acme/src, but what if you want to change your name? Then you just…

OK, inspired by the really cool Commitlint project which ensures you don’t just type “fix” when you do a git commit, I learned about a standard Conventional Commit format to make the lines useful. Basically, you can load into commitlint a standard set of rules for a pattern that looks…

Well for a variety of crazy reasons we just drove 11 hours to Montana. It was a great trip and an easy way to see some beautiful country (with suitably scary revelations), but one of the highlights was listening to the LensRentals Podcast. I first started using LensRentals an incredible…

Well, now that the rendering of LaTeX worked, might as well get diagrams working the same way. It’s the same idea, there is a WP Mermaid plugin and there is both Gutenberg block and there is a shortcode [ mermaid ]. Note that after you install a plugin, you need…

In these days of high gas prices. I was curious to see what the real energy cost savings are right to now. Back in 2017, we had the option to get a $5K rebate or unlimited free supercharging. This was because they dropped the price of the car by $5K…

Ugh, I’ve been trying to limp along with an Apple Watch Series 3 and it’s been hard. The thing doesn’t last very long battery-wise and is slow. Also at some point, I took a huge piece of glass out of the right corner but it still worked. Finally, it has…
