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.

Happy Holidays! From now through Cyber Monday, get Tumult Hype and Whisk 30% off: blog.tumult.com/2025/11/24/hol… #BlackFriday #CyberMonday

Tumult Hype 4.1.20 is now available! macOS 26 Tahoe users can finally get out of 'Squircle Jail' with an update app icon. Everyone gets bug fixes. Update now! blog.tumult.com/2025/09/29/tum…

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.

@richgraemebowen I'm trying to add my apps to your buy once software directory, but am getting a 502 error when clicking the "add your software- $10" button.

@wooster Zoomed by at the moment fireworks went off at the stadium.

Apparently yes

Was that a fighter jet I just heard in SF? Was in an elevator and it was loud even there.

So cool to see my friend's uber-cute capybara sled game released on steam: store.steampowered.com/app/3619230/Sp…

Am I going to need to send a cease and desist to google over "Whisk?" youtube.com/watch?v=fyFDzt…

@jsoncorwin @wooster @sfcatacombs The Commons also has a direct door into the 550 Laguna space (formerly the clothing store), and there's a bathroom there. Two seems okay.

@wooster @sfcatacombs That’s a lot of people for that one bathroom 😬

Amusing to see my old office show up randomly. That part of @sfcatacombs was very dark, even with the sidewalk glass.

just reviewing the apple developer guidelines

I decided to start blogging again! "Naming Things" is my list to help objectively score a great product name. blog.jmfd.me/naming-things/

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.

@wooster Perhaps not the whole reasons, but I found this to be illuminating on the recent trends: youtube.com/watch?v=3oIeLG…

Why do newly built homes look like they were designed by someone who has never seen a home before but only heard descriptions of them? Is architecture dead as a practice?

Heads up: We're discounting our apps 30% for a bit! blog.tumult.com/2024/11/24/cyb… #cybermonday #BlackFriday

@kartick_vad Without a doubt! That said, I'd personally and selfishly prioritize my use case because: - you can add an external battery pack, but I can't shed weight - 24h battery life probably handles a ton of long-life use cases already - There's low power mode to get even more life

@jmfd I respect your preference. That said, I wonder if there's a market for a 13-inch laptop with a 100 Whr battery and a low-power CPU and GPU, for a long life.

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)

Last night wasn't spooky enough? Check out @MaxZiebell's Halloween-themed Hype document where you have to enter gestures in order to save yourself from the monster: forums.tumult.com/t/monster-kill… (as an answer to: forums.tumult.com/t/a-halloween-…)

oh wait, that's the macOS team telling me this 😅.

My M1 Pro is telling me it is time for an M4 Max.
