💻 Apple just released the Xcode 26.1.1 update. And after using it for a few hours, I’m happy to report that the bug in Simulator that caused Macs to overheat and drain the battery is gone 🥳
🙏 Thank you, good developers at Apple! Updates like this are a huge quality-of-life improvement.

Xcode users. If your Mac is getting unusually warm running Xcode 26.1 (17B55) and macOS 26.1 check the Console for MercuryPosterExtension.ips files filling the crash reports. In ActivityMonitor, "ReportCrash" will be burning up your CPUs. It's related to SwiftUI Previews. FB20986632

Getting lots of developers in my email lately, asking for work. Not just low wage country developers either.

I’m religious when it suits me. More specifically, I worship gods. Those 10x engineers who can do stuff with technology I can only dream of being capable of.
Today, I’m praying to MxIris, who can look inside Apple’s private frameworks and extract all the internal Swift code like it’s nothing.

Just ordered a Fellow Prismo for my AeroPress.
I'm not into Espresso at all, but I do like a strong coffee as a base for a latté or some other milk-based coffee.
Any experiences?

Dilemma:
- Buy an M4 or M4 Pro Mac mini now, and have a lot more performance now
- Wait until the M5 drops, and buy the M4 or M4 Pro anyway for less money
Early 2026 is a bit late for me to upgrade, but the benchmarks have been seen in the wild already

As demonstrated by my friend Kaustubh Debnath on X, iOS 26 renders Liquid Glass UI in HDR! Taps on bottom nav bars trigger specular highlights, peaking at around 350 nits.
Screenshots and recordings can capture the additional luminance data in PQ EOTF with HDR10 🤯

The slam shut sound is missing though. Or that’s in the paid version?
Did you know your MacBook has a sensor that knows the exact angle of the screen hinge?
It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.

I got to meet one of my childhood heroes, Roberta Williams, and talk to her for hours and it's one of the coolest experiences of my life. That will only make sense to a narrow band of you, but I'm fine with that. Big thanks to @gameinformer.com for asking me to do this. Roberta Williams. The legend.

We connected King’s Quest creator Roberta Williams to comedy writer Mike Drucker, who may be her biggest fan, for a conversation about the series’ legacy and a generation’s connection to it.
