Some simple CSS layout classes, mostly using flexbox

Collection of (SVG based) patterns for use in hero UIs as a background

Demo showing CSS columns property, allowing newspaper-like columns with a couple of lines of CSS

Interesting tool to "write a letter" using HTML/CSS. Uses contenteditable & nice styling to format a "letter"

Utility site to view curated simple gradients. Useful for headers/hero UI patterns

Really great post on how to make a great team by @b0rk. Truthfully, it's more about being a great team member than being a manager and creating the team.

Invaluable post on the reflog and how to recover commits lost with git reset --hard

Good blog post on creating your own create-react-app style tooling package

Really impressed with Typora markdown editor:

Automated memory leak unit testing in JS

Uses the web User Timing API to record JS performance and send to Google Analytics

Better JS timing library. console.time() and console.timeEnd() have slight perf issues themselves. Integrates with console timing tab graphs

Made with the fantastic sweaterify by @kosamari
