For iOS developers that want to use the new PDF image catalogs in Xcode 6 (which automatically generate the @1x, @2x and @3x images so you don't have to add them individually) I have forked the repository and added them at https://github.com/programmingthomas/material-design-icons.

Steve Jobs blogged on Apple's main site https://www.apple.com/hotnews/, including the famous Thoughts on Flash article https://www.apple.com/hotnews/thoughts-on-flash/.

Objective-C uses Automatic Reference Counting (Garbage Collection has been deprecated - and ARC works a lot better than the GC implementation), and as Swift had to uses Objective-C's memory model it must also use ARC.

Furthermore, Apple did bring up a slide during the Platform State of the Uniform (slide 56 in the PDF) saying source compatibility wouldn't be guaranteed (but that converters would be provided) because the language will evolve. I can't imagine that they'll introduce dramatic changes that will break code generated by PaintCode, but it would be a pain if you have to completely regenerate your all rendering code with each update to Xcode/Swift.

I haven't listened to that presentation or read the PDF, but from what I read about it I would bet that 'evolve' refers more to the time until the official release than to the time after that. Of course the language will evolve, but it will be slower and shouldn't do so in incompatible ways.

Until official release, though, Apple may make huge breaking changes (change keywords, tweak the grammar, maybe drop a feature or two. For example, do we really need trap on overflow for integers in what, in the end, is a compiled language?)

The old Apple headphones were average (for their price), but overall the newer EarPods are much, much better.

This is a lot better than the conference selling out in 2 minutes like last year.

Apple also uses a similar strategy with the iPhone. The iPhone 4 and 5 both made major form changes (retina display and screen shape) whereas the 4S and 5S were focussed on refinement (faster CPU, 64-bit CPU respectively). It has also been noted (possibly on the Accidental Tech Podcast, or somewhere similar) that a 'tick' year for the phone tends to be a 'tock' year for iOS and vice versa; iOS 5 and iOS 7 (released with the 4S and 5S respectively) were bigger changes than iOS 4 and 6.

A lot of old articles (some as early as 2011) have been popping up in the popular list on BBC News. In the past this had been due to it suddenly being shared on social networks although I can recall one occasion when it displayed a list of the most popular articles from exactly one month before.

Or one participant may not be European.

These standards don't just cover 'word documents', they also cover other Office types for spreadsheets and presentations. HTML+CSS is a terrible idea for a spreadsheet standard.
