Goodbye, Universal Apps

Last week, Apple released iPhone 6 and iPhone 6 plus. Both phones have a bigger display than the previous phones. If you take a look at the display sizes that are supported by iOS 8, you now have:

Bold Predictions

Today is the keynote to Apple’s annual world-wide developer conference. As many developers, I’m at the same time looking forward to and scared of what might come. The huge design changes in iOS last year are widely considered to be continued within Mac OS. New hardware might be announced, not showing the iPhone 6 would be a big surprise.

Hardstatus in screen (& other terminals)

When Steve Jobs presented Mac OS X, he named it the operating system for the next decade. This decade has passed by some years ago. What’s next?
