#Making Persistent Live USBs is Harder Than it Should Be 9/14/2016

What used to be easy with Ubuntu's Starup Disk Creator (usb-creator-common + usb-creator-gtk) is now a lot harder than it should be on UEFI systems. Some version before v0.2.66 have a bug that allows you to specify live usb persistence, however it doesn't actually work. Versions > 0.3 have removed this functionality completely (wtf!).

An alternative that worked for me was using mkusb from an installed Ubuntu distro (I could not get this to work creating live USBs from live USBs).

Steps on Ubuntu 16.06 include:

Procuring large schematic dataset

Use GitHub API to batch download .sch files.

1. GitHub API requires you to limit searches to users, orgs, or repos. So we first have to get a list of repos that use the KiCad or EAGLE "languages".

https://api.github.com/search/repositories?q=language:kicad&per_page=100&page=1
https://api.github.com/search/repositories?q=language:eagle&per_page=100&page=1
