Marked Share just took another big step toward full folder sync.

Callouts (as popularized by Obsidian and GitHub) are one of those features that seem simple until someone really puts them to work.

Howzit has always split build notes into topics using Markdown headers.

I built a new app because I was tired of scrolling past jokes, quote-posts, and the same article six times on social media.

People are digging TerminalWidget, which I’m both surprised and delighted by.

Graffiti Moe started as a terminal thing on purpose. curl a random spray, slap one up with a one-liner, feel like you’re tagging a wall that only nerds walk past.

Widgets that just sit there and look pretty are fine.

I’ve been sitting on this one while I got TerminalWidget launched.

Graffiti Moe has been a moderate success — enough people spraying the wall that it felt worth pushing further.
