Krstić, formerly with [One Laptop per Child][olpc], has announced that he’s joining Apple. He doesn’t reveal anything about what he will be doing1, but he’s a bright mind, and I’m sure Apple have made a catch here.
Knowing about his past, I’d venture a guess and say he’s going to be on their security team, but I have no other grounds than assumption to build this on. 
This is Simply Jonathan, a blog written by Jonathan Holst. It's mostly about technical topics (and mainly the Web at that), but an occasional post on clothing, sports, and general personal life topics can be found.
Jonathan Holst is a programmer, language enthusiast, sports fan, and appreciator of good design, living in Copenhagen, Denmark, Europe. He is also someone pretentious enough to call himself the 'author' of a blog. And talk about himself in the third person.
