"CRDTs as a temporal data structure"
@paulbutler.org gave a brilliant talk, explaining how to use the Yjs CRDT toolkit to store temporal data.

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.

Claude Code now supports resuming sessions, which means that session logs (including tool/llm calls) are stored locally. My curiosity got to me, I figured out the format and wrote a CLI tool to dump specific conversations github.com/paulgb/claud...

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.

I met a couple who introduced themselves as engineers but instead of writing JavaScript they drive trains.

Years in, WebAssembly on the server remains incredibly secure because you still can't do anything with it.

Always nice getting surprise #ptpx mail!

Never ask a barber if you need a haircut or a foundation model company how long your tool call descriptions should be.

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.

This was fun to host! We’re doing it again in NYC next week, it’s full but I’ve saved a few spots for people building things on MCP ;) lu.ma/mcp-nyc

Thinking of doing a Cursor vs. Windsurf video where I just use Claude Code in the terminal of both, as a bit.

People who primarily don't use Windows, how do you test things on Windows? Thinking of getting a cheap Windows machine, but wondering if there's a cloudy way.

Setting clocks for DST. My microwave clock has AM/PM. How down bad do you need to be to want to know what half-day it is from a microwave?

It seemed impossible to me that Gemini was able to decode a hidden message this fast. I finally had a chance to reconstruct the chain of thought and tool calls from logs and figure out how it did it.
After my post on smuggling arbitrary messages through unicode, some people asked me if AI could decode it. Gemini Flash is pretty fast at it! Have had good luck with Claude too. So far no dice with OpenAI models.

This uses block.github.io/goose/ and forevervm.com
