1. Developers Angry about Windows 8.1

Microsoft has begun sending its latest Windows 8.1 to its PC and tablet makers. Developers and IT pros, however, will have to wait until October for the OS update. Many developers are upset over this wait period, since in the past an RTM release indicated that the OS was also ready for customer use. Because there are now so many devices the OS has to work with, however, this is no longer true, and Microsoft now has to adapt and roll out their delivery times in a different way than before.

2. Facebook Changes the Way Users Can Upload Photos

As of Monday, Facebook is now allowing its users to created shared photo albums. Albums, which were previously uploaded by a single person, can now be accessed by up to 50 contributors. This new feature was developed during a Facebook company hackathon, a time period during which employees work together to figure out new platform prototypes.

3. Trouble for Bitcoins?

Bitcoins have gained some traction in being seen as a legitimate currency. Bitcoins are not backed by any government, but are, instead, created by a computer program. This week, representatives from its largest lobby group met with federal law enforcement officials and financial agencies in order to try and clear the air. Authorities say they are worried that bitcoins will be used to fund illegal activities or as a funnel for money laundering.
