I love the art and design of PyCon Davao. I think it's inspired by a regional art style. Can't wait to meet the creator and ask them a zillion questions about it. pycon-davao.durianpy.org
When I was a kid I referred to my language as "Americanese" because I didn't know any better.
Once I gave a tech conference lightning talk about composting for helping gardens. Materials I covered in the talk that can be composted were vegetable and animal matter, including humans. 😲🧟🪦 youtube.com/watch?v=DW0Bxm…
As someone who has always had to fight the foolish urge to clean up HTML output formatting when he does web stuff, this is a dream come true.

if your executives read gartner it's time to find new execs
Pro-tip: When @audreyfeldroy makes an architectural suggestion on a project it's a good idea to quickly follow up on it so you don't turn your project into copy/pasta. 🍝🍜
I documented how I created a 74-second promo video draft for a new framework, air, in 30 minutes How to stay in control of AI: ✅ Injecting human taste ✅ Correcting AI errors ✅ Improving code examples ✅ Syncing animations to music, and more. elite-ai-assisted-coding.dev/p/from-zero-to…
Today I started over on a project in a new branch/PR. Doing so allowed me to go super fast because: 1. I now had a deep understanding of the spec 2. In the new branch I only had to good stuff 3. I don't need to worry about git cleanup, it's all new 4. It forced me to take a break
TIL the PSF board vote had 13 candidates for 13 positions. 😮 At least one of the candidates I very much object to being in the board. There needs to be more candidates next time. I don't want to be on the board, but this kind of thing is troublesome.
I spend much of my work day coding something out that isn't going to work. Need to backtrack and start over. 😬
I'm a fan of @AndyMasley's essays on climate change and AI. He's a master of clearing the smog from fossil fuel-powered FUD on the topic.

Uma trained Brazilian Jiu-Jitsu. Then we took her to the library where she read a girl's chapter book in 20 minutes. I ❤️ this kid.
Wahoo! Good news!
I consider this very good news! Welcome back @GrahamDumpleton! grahamdumpleton.me/posts/2025/09/…
Attribution matters. I am a zealot about adding people as co-authors to my git commits when we pair. And if I need to merge two projects together ever again, going forward this is how I'm doing it. daniel.feldroy.com/posts/til-2025…
A good practice for any coding team is the Thirty Minute Rule. daniel.feldroy.com/posts/thirty-m…
I really enjoy using @marimo_io as a notebook tool. The reactive cells means I don't have weird surprises showing up at the worst possible time.
I know GitHub stars arguably don't mean anything, but this is nevertheless still exciting.

Our six-year-old daughter Uma absolutely understands what reverse psychology is, considers it a fun game. Sometimes when she wants to eat all her meal or go to bed she asks quietly for us to tell her not to do it. Then she happily does it anyway.
