These are my notes for installing Arch Linux with full-disk encryption on a HDD. The installation process changes significantly for an SSD.
$ lsblk #list devices
$ timedatectl set-ntp true
I will create the following partition layout...

Python script to determine optimal resistor combinations. Its arguments are a desired resistance and either 10%, 5% (default), or 1% tolerance value. I intend to refine and expand this code and then implement it in several other languages (Matlab, Lua, TI-BASIC, ...). Based loosely on http://www.qsl.net/in3otd/parallr.html.

This file contains my notes from installing Arch Linux on my new(er) computer. It uses dm-crypt and LUKS to encrypt the entire hard drive (including /boot). So far, it has preformed well. NOTE: some of this is specific to my machine, but the encryption and filesystem setup is not.

Python script that downloads xkcd comics to basePath, prepends the comic number to the filename, and puts the alt text in 0-alt.txt. I recommend setting basePath to an absolute path.

New and updated version of backup.sh. The old script had many limitations and was often unreliable. This script, while requiring slightly more user input, is much more robust.

useful code snippet from http://stackoverflow.com/questions/954302/how-to-make-a-programme-continue-to-run-after-log-out-from-ssh
Assuming that you have a program running in the foreground, press ctrl-Z, then:
[1]+ Stopped myprogram
$ disown -h %1
$ bg 1
[1]+ myprogram &
$ logout
If there is only one job, then you don't need to specify the job number. Just use disown -h and bg. Explanation of the above steps:
