Learning Cron

Last Updated 2025-12-23

I'm ashamed at how many times I've stared at a * * * * * and wondered what to do from here. Well... I'm a little better off now due to a game that I've recently vibed with OpenCode using the newly released GLM 4.7.

little note: GLM 4.7 I'm super impressed with. Feels alot like Sonnet 4 to me... and at $10AUD a month its an absolute steal.

Cron; but gamified

The 'game' asks you to produce various cron expressions using natural language. It's forked from the crontab-guru TUI built with Bubble Tea that helps you understand cron expressions using natural language based on the crontab guru site.

Clone and build the game from here.

git clone https://github.com/samuelstranges/crontab-guru
cd crontab-guru
go build .

# Run game
crontab-guru --test

# Run game in 'hard mode' (no real time preview)
crontab-guru --test --hard
