I just went to look at my crontab again. Some highlights (lowlights?):

- Turning lights on/off around the house, because I found cron to be a more reliable scheduling agent that the one built-into my Wave software when I first set it up.

- Testing network performance (ping times to various locations)

- Fetching a mail account and processing the messages for an automation I have setup for some things.

- Updating online weather services with data from my weather station.

- Kicking off data gathering/update jobs.

You know, cron is simple... but so directly useful.

I moved some stuff out of cron into systemd and although it worked, it was over-complicated in an infuriating way.

I realize systemd is useful, but the implementation is like trying to navigate through a teenager's bedroom trying to find something.

He told it: random ones.
