Science Advances has a paper on habitable temperatures: At wet-bulb temperature (equivalent to 100% humidity) of above 35° Celsius (308K) a region becomes inhabitable to humans because sweating does not work anymore; higher temperatures are only tolerable with lower humidity. Becomes more relevant with climate change (xkcd).

Like the Azeron speedpad, the Squeezebox keyboard prototype has only one row at the bottom, and expands with forward and backward finger clicks; cannot be bought though. The Breeze is a more conventional staggered column keyboard. Both ignore mousing completely. Slightly related: Why keyup on Linux is not easy to program for.

Adam Williams explains booting with UEFI firmware: While BIOS firmware looks at the MBR of attached drives, UEFI looks at the GPT tables of attached drives to find a vfat partition with type identifier EFI, where one or more boot managers reside. Can be configured from within an OS; try e.g.
efibootmgr -v for info.
