“Apps genius” - Colleen. I used to work on making Twitter a bit healthier, then that all went to hell. Now I make puns, @plinky.app, and teach @ build.ms.

Hi, I’m Joe! I used to work @ Twitter on all the hard things like misinformation, disinformation, harassment, and civic integrity. I also spent a ton of effort on little improvements to make people’s lives better. These days I’m an indie developer making it easy to save links for later, with Plinky.

To all the iOS developers starting to discover just how powerful AI is for coding — I'd love to teach you a workshop. I’ve run dozens of them and they've made a tremendous impact. I've also taught hundreds of people at a non-profit, and feel confident I can level you up a lot in just a few hours.

I am once again wading into the discourse. Special appearances by @stroughtonsmith.mastodon.social.ap.brid.gy and @manton.org, both of whom I respect.
Steve thinks we're heading to a world where nobody reads the code. Manton thinks that's not the case. I think they're both right…ish… with caveats.

Read The Code (Sometimes)
Should you read the code agentic systems write, or it all assembler in a world of AI-assisted coding?

A critique of AI that I really agree with, because it's not rooted in easily disprovable premises like "LLMs are stochastic parrots" or "AI can only produce the average content".
Whatever the productivity gains promised by LLMs, they result in heavier workloads—and that leads to workers experiencing “cognitive fatigue, burnout, and weakened decision-making.”

AI Doesn’t Reduce Work—It Intensifies It
One of the promises of AI is that it can reduce workloads so employees can focus more on higher-value and more engaging tasks. But according to new research, AI tools don’t reduce work, they consisten...

Finally pulled the trigger and upgraded to macOS 26 overnight so I could better design Plinky for Mac around the new design language. Alan Dyed for this.

There is a common Republican critique that goes something like "it's unpatriotic to not support your country's choices whether you agree with them or not". An obvious counter to this though is to ask whether they would support all of Joe Biden or Barack Obama's actions on the grounds of patriotism.

If I wasn’t so busy I would try this with Swift… somebody else please do this so the iOS community can have some nice AT proto apps and tools.

Nothing more embarrassing than the train conductor closing the door in your face and saying "sorry man, tried to warn you to hurry up" after I ran up the stairs.

Spent the last hour working with Codex to redo Plinky's routing layer for the iPad and Mac, and boy did it do such a great job. This is a task I've really struggled with, had a very smart contractor build out v1 and v2, but now I need more for it to work well across devices and I looove the result.

I've always had to weigh the tradeoffs of "spend time building out a debug menu for internal feature flags" and "use the time to build features that users provide value". With the right setup for a parallel working structure, now I can do both. 😄

Wrapped up a workshop and came back to Opus-4.6 and GPT-5.3 Codex. Maybe let a guy breathe before having to update the notes for my next session?

As I’ve been saying, the primary reason iOS developers have been saying AI isn’t “there yet” is because they try to live in Xcode. Now that Xcode finally has good agentic tooling they’re rewriting 5,000 lines of Objective-C in 5 minutes and declaring software is over.

If there's one thing anyone should know about @buttondown.com it's that they have hands-down the best support of any company I've ever used. It's almost like someone drops whatever they're doing to respond to you, and most issues I've had that were real problems got fixed within 24-48 hours.
