T4T5

a fun side effect of building airdrop for linux: we're using wifi cards in ways nobody has before, and finding driver bugs! 😅

Caldir by @t4t5.com is just great. Finally a backup from Google Calendar that is under my control. caldir.org

reactjs is my passion

wonderful news!

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-...

First lightning talk today: @t4t5.com shares his passion about plaintext applications 🤓

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

i wrote a post about the UK's increasingly authoritarian approach to digital privacy t4t5.com/privacy-uk/

feels like I’m 10 years old again 🥹 such a beautiful device

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

soo nice to have a scriptable calendar

x402 is the future

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...

these L2s, they're laughing at us. we will make them pay their fair share with reciprocal blob fees

I built a website showing where the UK government spends its money https://wheredoesitallgo.org

"very nice stock markeut you have over zere. would be a shame if something 'appened to it..."

can the eu just chill and let us have good things

feel like pure shit i just want her back x
