  • Why WhatsApp Only Needs 50 Engineers for Its 900M Users.
    Part of the trick is that the company builds its service using a programming language called Erlang. Though not all that popular across the wider coding community, Erlang is particularly well suited to juggling communications from a huge number of users, and it lets engineers deploy new code on the fly.

Yes, there are only a few dozen of them. But that too is the point.(Wired)
  • Google’s Rachel Potvin came pretty close to an answer Monday at an engineering conference in Silicon Valley. She estimates that the software needed to run all of Google’s Internet services—from Google Search to Gmail to Google Maps—spans some 2 billion lines of code. By comparison, Microsoft’s Windows operating system—one of the most complex software tools ever built for a single computer, a project under development since the 1980s—is likely in the realm of 50 million lines…

  • Developer Daniel Pasco explained in a blog post that Apple’s upcoming tvOS — which will power the new Apple TV — doesn’t support webviews, which means apps for the device won’t be able to display Web content.This makes it a lot harder for developers to build in features like browsing websites, opening links from apps like Twitter or RSS readers, or displaying frequently updated information, such as sports scores.
