...and made by someone with a background in "old fashioned" print design. An engineering background would have been required to make this just ~6 months ago. Claude and a few days of work resulted in a fully functional tool. It was fun seeing this built and used in person. (2/3)

So if you've got an idea that could be an app, now is the best time to [insert nike slogan]!

I heard that Mark Zuckerberg hates Liquid Glass as much as the rest of us, and gave Alan Dye a pile of cash to stop messing up macOS.

Apple just made a nano-texture display on its hardware to reduce the issues with using glass. Then they added all the flaws of glass back via software... ...The call is coming from inside the house! 😱

I just released my first vibe-coded app ROCK PLANNER for iPad, and it was SO MUCH fun. I haven't enjoyed writing software this much in years. Rock Planner is my attempt at a new iPad daily planner app built for Apple Pencil. It integrates with your calendar and makes creating daily notes a cinch. When I started, I didn't know Swift or SwiftUI, but that wasn't a problem. I began experimenting with Cursor to see how far I could take it, and I was surprised to find out the result was... ALL THE WAY TO SHIPPING. Granted, I have a lot of experience with Objective-C and UIKit, but I hadn't touched development in years. In the hands of a reasonably skilled developer, Cursor is a superpower. So check it out on the App Store: Rock Planner.

There’s nothing “just” about “just hopping on a call.” Let's say your colleague asks you a reasonable question. You could take 5 minutes to write a cogent reply. But instead, you say, “Let’s hop on a call.” When you say this, sometimes what you really mean is: “I don’t want to do the work of clarifying my own thinking. And I believe it’ll be easier to think out loud and answer in a live conversation.” My response to you is: I do not want to hop on a call because you are too lazy to write a cogent message. If you don’t want to invest a few minutes to write a reply to a reasonable question, why should I listen (with no 1.5x button) as you meander in real time? GTFO. To be clear, I am not blindly against live meetings, nor am I blindly in favor of async communication. There are plenty of reasons to hop on a call, and I hop on calls all the time. But let's be intellectually honest about whether we could share a perfectly good response in writing, if we took an extra beat.

The battery characteristics on the M4 vs M4 Pro vs M4 Max are interesting. If you were hoping for a battery life upgrade like me from the M1 Pro, going for the M4 Max would not do very much. (That said, I would still happily make the tradeoff of *less battery* for less weight)

Judging by this video, the Mac mini will lift itself up when you need to press the power button.

Looking for a full time iOS/macOS engineering job after 8 years of freelancing! I'm a hybrid engineer/designer (engineer first) so a role that uses both skills would be ideal but not required :). If you know any potential matches, would love to hear from ya! Thanks y'all ❤️
