I’ll let the original article speak for itself (c/o Steven Vaughan-Nichols):
Yesterday, we published a blog post lauding an extremely important app privacy feature that was added in Android 4.3. That feature allows users to install apps while preventing the app from collecting sensitive data like the user’s location or address book.
After we published the post, several people contacted us to say that the feature had actually been removed in Android 4.4.2, which was released earlier this week. Today, we installed that update to our test device, and can confirm that the App Ops privacy feature that we were excited about yesterday is in fact now gone.
Over the last few weeks, the first round of 802.11ac WiFi devices have started to emerge. In essence, 802.11ac is a supercharged version of 802.11n (the current WiFi standard that your smartphone and laptop probably use), offering link speeds ranging from 433 megabits-per-second (Mbps), all the way through to multiple gigabits per second. To achieve speeds that are dozens of times faster than 802.11n, 802.11ac works exclusively in the 5GHz band, uses a huge wad of bandwidth (80 or 160MHz), operates in up to eight spatial streams (MIMO), and a utilizes very fancy technology called beamforming. For more details on what 802.11ac is, and how it will eventually replace wired gigabit ethernet networking at home and in the office, read on.
