When I was getting my BMath people would ask “oh, what will you do with that, teach?” and I’m jealous of people taking math now who can come back with “yeah that or pope”.

My pet peeve is when people use “misnomer” in a way that is in itself a misnomer.

I replaced all my fancy notetaking tools with a vibecoded bash script called `note` that opens ~/notes/{date}.md in an editor, and it's been great.

Now that it's so easy to create software for personal use, I want a way to have a bunch of personal mini apps in a monorepo and automatically deploys all of them behind basic password auth.
Before I build it, does this exist? Ideally something I can self-host on a VPS.

This is a talk I've wanted to give for a while, and I can't think of a better place to give it!
We’re excited to announce that @paulbutler.org co-founder of Jamsocket, will be speaking at Local-First Conf 2025!
Paul will explore how CRDTs can act as temporal data structures, enabling features like revision history by delta-encoding changes over time.

Very speculative question for people smarter than me: if we ran 100 replays of humanity from 1955 or so, in many is there a manned moon landing before y2k?
Thinking about failure scenarios like a series of failures dampening political support, or global events destroying the necessary conditions.
