The human is the loop

Sidebar.io

A designer steps away from AI for a few weeks and comes back with a clear head. The reflection is honest: a lot of AI usage was neither productive nor healthy. A useful reset for anyone feeling the pull to automate everything, including their own judgment.

How to make your design system agent-ready

Sidebar.io

Stop dumping your entire design system into one design.md file. Agents choke on monoliths. The fix is modular, structured, and machine-readable documentation. This is the practical work that separates teams whose agents work from teams whose agents hallucinate.

99% of my website traffic is bots

Sidebar.io

A year-long war against scrapers on a 1.5 million-page site. The author documents what worked, what failed, and the brutal math of bot traffic. If you are building for the open web, this is your reality check. The web is not what it used to be.

Morphicons

Sidebar.io

Morph any SVG icon into any other with spring physics. Zero dependencies, works across React, Vue, Svelte, and vanilla JS. A small, elegant tool that makes micro-interactions feel alive without the usual animation overhead.
