Ask HN: What are the implications of Apple moving to 64-bit architecture?

It's very difficult to find anything related to this subject that hasn't been overshadowed by either "4GB RAM" or NSA discussions.

Is there anyone out there that can give an overview of what this move to 64-bit really means?

Does it signal Apple hoping to develop the A7 into the notebook/desktop lines of computers?



They're planning ahead for http://en.wikipedia.org/wiki/Year_2038_problem


NSDate is luckily already using 64bit precision, so every current iOS device should be able to keep ticking seconds _far_ into the future.


Worsened security; they have 32 bits more to secure. I have no doubts it will be a lot easier for developers to jailbreak it with this new architecture.


For those not in on the joke, ASLR on 64-bit is actually a lot better than on 32-bit; https://en.wikipedia.org/wiki/Address_space_layout_randomiza...


Unless apps and browser plugins appear which weaken ASLR, like several recent versions of DropBox in 32-bit & 64-bit DLLs, Windows 7 x64 SP1 - http://codeinsecurity.wordpress.com/2013/09/09/installing-dr... How vulnerable is ASLR in OSX?
