[1]Your Wireless Keyboard May Be Betraying You -- Bastille, a cybersecurity company, has shown that hackers can easily intercept transmissions from eight non-Bluetooth wireless keyboards. Experts demonstrated how a $40 radio transponder combined with a $50 antenna could eavesdrop on the signals of budget wireless keyboards from Anker, EagleTec, General Electric, HP, Insignia, Kensington, Radio Shack, and Toshiba. Bluetooth and wired keyboards, however, are not vulnerable to the methods used in this attack. It's a reason to avoid wireless keyboards that depend on proprietary transmission systems.

'Carpool Karaoke' is a spinoff of the popular 'The Late Late Show with James Corden' bit, in which he drives celebrities around as they sing songs. Although it doesn't sound as if Corden will host the new show, it is, nonetheless, a big 'get' for Apple Music.

This exemption includes music videos, as well as future video content on Apple Music, such as the upcoming 'Carpool Karaoke' series from CBS.

The Wirecutter goes over the complex reasons why mobile device battery meters are often so inaccurate. The article describes the different variables that go into computing remaining battery charge and concludes that battery meters can, at best, provide only a guess of the remaining charge.
