YouTube streams video and audio separately and the web player/app combines them on the fly. Due to this, the audio bitrate is not directly affected by video quality like in the past. Rather, YouTube can stream the video and audio it deems appropriate for a given device and connection. It can also adjust one during playback without affecting the other.

The audio you hear during a YouTube video will usually be 126 kbps AAC in an MP4 container or anywhere from 50-165 kbps Opus in a WebM container. Changing video resolution (360p, 720p, etc) in the video settings will probably not impact the audio stream, but it is likely that your connection performance will.

Yahoo recently started displaying a large advertisement for their Chrome extension when you try to access your Yahoo Mail inbox (mail.yahoo.com).

If your browser clears cookies each session, you'll see it every time you access Yahoo Mail with a new browser session. This is beyond obnoxious:

Most Android devices allow you to connect a USB drive, or other various USB devices, even if they don't have a USB port. The capability comes from a USB OTG (on-the-go) host adapter that plugs into the micro USB port on the Android device and has a full-size USB receptacle.

Building a flying machine in Besiege can be very difficult. Building one that can hover and make precise movements, while still carrying weapons, is even more difficult. With version 0.04, the developers made that a bit easier with the addition of Balloons. But you still need movement and elevation control.
