Google's Project Fi is a great cell-phone service, but the data-only SIMs make it incredible for network projects! Project Fi is a play on the term "WiFi" and is pronounced "Project Fye", as opposed to "Project Fee", which is what I called it at first. Several features set Project Fi apart from other cell-phone plans.

Bootable USB drives are a great way to try out a new Linux distribution to see if you like it before you install. While some Linux distributions, like Fedora, make it easy to create bootable media, most others provide the ISOs or image files and leave the media creation decisions up to the user. There's always the option to use dd to create media on the command line—but let's face it, even for the most experienced user, that's still a pain. read more
