an unfortunate side effect of LLM-assisted exploits is that people will be more wary of sharing their setups i used to always have my dotfiles public on github, but now I don’t dare to do that anymore. it’s just an unnecessary risk at this point
my @localfirstconf.com talk is now on youtube! it's a love letter to plaintext weirdos, and a case for why the best way to build AI apps is to add zero AI features www.youtube.com/watch?v=2ZEB...

renCal just crossed 100 stars on github! 🥳 i’m continuing to bet on plaintext-first software in 2026 github.com/t4t5/rencal

a cool thing about caldir: anyone can write a custom provider for fetching calendar data here’s one that reads calendar feeds from the AT Protocol using the "community.lexicon.calendar.event" lexicon: github.com/t4t5/caldir-...

i finally built my dream Linux calendar on top of caldir local-first, keyboard-driven, agent-friendly rencal.org

claude code has been borderline unusable for me lately it fights simple instructions and spends 10+ minutes thinking about changes that should take 30 seconds i moved my setup to pi + GPT 5.5 and the results are sooo much better
i'm pretty much doing open-source full-time now haven't sat through a standup or gotten a slack ping for months god i love being free
I wanted my AI agent to be able to read my calendar. Turns out the easiest way is to just make a directory of text files. So I built caldir caldir.org 🧵
Caldir
Your calendar as a directory

some changes i've made to my tech stack to optimise for agent workflows: 🚫 Notion/Notes ✅ markdown files (with Obsidian) 🚫 Todo app ✅ todo.txt 🚫 Quickbooks ✅ beancount files 🚫 Google sheets ✅ csv files 🚫 Recipe app ✅ cooklang files
my biggest bet for 2026: invest in plaintext productivity t4t5.com/plaintext-pr...
The return of plaintext productivity
What happens when everyone starts optimising their software for LLMs over humans?

the thing with vibe coding is that writing the code was never really the hard part It’s like an author saying they could write Harry Potter because they can generate any sentence
these L2s, they're laughing at us. we will make them pay their fair share with reciprocal blob fees
you can now install the ordiscan MCP server and ask your AI assistant about ordinals ✨
I built a website showing where the UK government spends its money https://wheredoesitallgo.org
