👋 Greetings, Bluesky!
I've been a developer in the Apple ecosystem since Mac OS 7. Got test-infected. Wrote a book for iOS developers.
I'm an Exvangelical (not a typo), originally from Japan, love music (especially prog and fusion).

Wow. It's been so long since I was TDDing in a pre-Swift world, I'd forgotten how CRAZY FAST Objective-C was to build. The feedback is so fast, it changed things. Badmouth Objective-C all you want, but for a TDDer like me, it was a joy. https://youtu.be/NthPd0zbua4?si=-ZDlEu79gKPs4p6Z&t=1707
How to Do UIViewController TDD
I'm often asked, "Do you do test-driven development on view controllers?" Sure! Here's how, taking advantage of IBOutlets and IBActions. https://qualitycoding.org/uiviewcontroller-tdd/

I sent messages to my 2 senators, and to Chuck Schumer.
Call your senators. Let them know how you feel.

Barack Obama Steps Into the Fight for Fair Representation with Prop 50 Support
Barack Obama just made waves in California politics by endorsing Proposition 50 — a reform effort aimed at redistributing representation more fairly across the state. This isn’t just about California; it’s about setting a national precedent against states like Texas that manipulate congressional power through population and redistricting maneuvers.

So gross, first because it excludes anyone with a spouse or kids, who don’t have those kinds of hours to give. Second, the overwhelming majority of startups fail, and most aren’t even acquired. All their effort is simply wasted. Just pointless misery.
The grind culture that birthed many Big Tech companies from Google to Amazon is back.
As the AI race heats up, startups are promoting hardcore cultures like “996,” or working 9 a.m. to 9 p.m., six days a week.
