The popularity of flat design in digital interfaces has coincided with a scarcity of signifiers. Many modern UIs have ripped out the perceptible cues that users rely on to understand what is clickable.
After reading this discussion, my current conclusion is that we've totally misunderstood the impact of the attack, and that the security of our bittorrent downloads is still good enough.

After you set it up in your data center or in the cloud, your configured buckets will be available as NFS mount points.

Android Marshmallow introduces a redesigned application permission model: there are now only eight permission categories, and applications are no longer automatically granted all of their specified permissions at installation time. An opt-in system is now used, in which users are prompted to grant or deny individual permissions (such as the ability to access the camera or microphone) to an application when they are needed for the first time. Applications remember the grants, which can be revoked by the user at any time.
