Quick references for everyday development tasks.

What are these cheat sheets for?
Each cheat sheet condenses the syntax you reach for most into a single searchable page, so you can confirm a pattern or command without leaving your editor for long-form docs. They cover regular expressions, cron scheduling, and Git — three areas where the exact syntax is easy to forget and expensive to get wrong.
The regex sheet lists character classes, quantifiers, anchors, groups, and lookarounds with examples. The cron sheet explains each field and the special characters used to build a schedule. The Git sheet groups the everyday commands for branching, merging, stashing, and undoing changes. All of them are free, need no account, and load instantly.
