I have a couple of scripts that I’d like to run at night, but I also want to leave my machine suspended to RAM overnight to conserve energy (and reduce noise, the fan is a beast!). So this is just a note for myself about how I went about it this time, using rtcwake and crontab. Here’s the crontab I originally had, which is triggered once a day in the afternoon:

I never seem to have got into the habit of writing tests as I code. That’s bad, I know. But there are so many excuses that prevents it, “oh this is just an exploratory thing”, or “Karen and Chad really needs the report/tool soon, no time for test”, or whatever else that might get in your way. Plus there’s a tendency to just use the million open-source projects out-of-the box, and expect them to do what you think they do.

Time zone is such a messy subject, and I don’t even know what to start with. At my previous job I had this photo saved from a stackoverflow answer: so that every time I need to do some time zone conversion magic, I have a quick reference to go to. Because seriously, how do you expect anyone to memorize all that? Today I’m playing with some time zone stuff again for the API with my autotrader database, and encountered a new problem/feature that somehow entirely evaded my attention in the past.
