We’re really trying here, but as you know “There are 2 hard problems in computer science: cache invalidation, naming things, and off-by-1 errors.”

My podcast player side-project thingy is going well, got a web version going too, and it's all deployed. Apps are on Testflight. First time since 2018 of having my own stuff ready to go out there! React Native and Expo are magic.

I understand why someone would use AI coding assistance, it’s great when you know what you want to build and know mostly what you’re doing. What I don’t get is trying to one-shot things. What’s the point? I can see the value in it as an LLM tech demo, but for a product? Nah.

I love how Claude Code helps me overcome "writer's block" on my side-projects. I wanted to write this podcast player since forever (it's highly customized to my usecase, sync server and device) but couldn't bring myself to do RSS parsing for the thousandth time in my career 🥱

I'm experimenting with a way to show how DOS games render themselves. Basically I'm recording a lossless video of the game running on a very slow (virtual) CPU, then removing all the frames where nothing happens, and I'm playing it back sped up a lot.

@ericmigi.com Hi Eric, can’t wait until I get my watch in December. Is there a way for software developers to get a dev board? Or emulator is the best way forward for now?

Yeah, Cabel's talk is great and I recommend watching it. The reason it's great is: 1. Cabel is just being himself 2. he's talking about something he's passionate about 3. he knows what he's talking about. If you have those three things, everything else just falls into place.

A couple of years ago, I started playing with PalmOS development. Code/Syntax/Capabilities were pretty limited obviously, but I was amazed by how little mobile development workflows have changed. look at this thing! IDE + Emulator/Simulator. This stuff is from 20-30 years ago!

lots of folks are using expo go in ways that we don't intend or support, which can lead to frustration for them when a new sdk version is released. we've put a bunch of work into trying to clarify the constraints of go vs dev builds, and will keep doing it. here's another go expo.fyi/expo-go-usage
