I think this is the main problem in the tech industry. It works perfectly for coders, but not any other discipline so far. Sure, they will make money but I'm not sure if that will be enough.

I'm so happy to have finally found "homemade" Panettone!
I first tried it thanks to an Italian colleague who brought one baked by his Nonna, and it was absolutely delicious with the soft and fluffy texture. I've tried store-bought versions before, but none of them came close.

This was my best app launch yet, over 1.000 downloads in Germany! I really wish Apple provided a city-level breakdown so I could see how many came from Hamburg.
My guess is that Hamburg has around 500.000 iPhone users, so there’s still a long way to go. :)

Custom Product Pages are perfect for Franzbrötchen, but I wish Apple would allow you to add keywords for each custom page instead of limiting you to picking from the existing keyword pool.

It is approved in the first try! I was planning to release it next month, but since it's already approved, why not release it tomorrow? :)

Over three years ago, I had an idea for an app but knew little about iOS development. Since then, I've released 9 apps while gathering resources and refining the concept. In the past few months, I've spent 100+ hours building it and just submitted it to the App Store. And the best part? It's free.

Looks like OpenAI started to limit the free usage of ChatGPT. Well, someone has to pay for the compute I guess.

Well, even I quit iTerm, the update didn't work.

This is new on macOS 26. Normally, when I leave iTerm open, macOS can't update the system because it can't quit iTerm. This notification will definitely remind me to quit the app :)

Many people assume the iPhone Air has worse battery life due to its thin design. While that's true compared to the iPhone 17, it actually offers the same battery life as the iPhone 16 Plus.
