Change the colour of the fish shell git prompt if source files are newer than build files. Set your prompt to fish_git_prompt then. Add this line to the bottom of ~/.config/fish/functions/fish_prompt.fish
 #Tests if source files listed are newer than the build
    set currentTime  0
    set rebuild false
    if test -e (pwd)"/"srcList.fish; and test -e (pwd)"/"buildList.fish

Samathy / Arduino_ArchLinux_libtinfo_missing
Last active February 3, 2017 19:35
Fix for -> Uploading a sketch to an Arduino Nano fails on Arch Linux 03.02.2017
Attempting to upload an Arduino sketch to an Arduino Nano fails with the error: 'Failed to find libtinfo.so'
libtinfo is a dependency of avrdude. libtinfo (as far as I can tell) is a depreciated lib who's functionality is now part of, and shipped with, ncurses.
A dependency of Arduino, avrdude, uses the no longer avalible libtinfo.so.
The Arch AUR Package 'libtinfo' symlinks the relevent files, but does not fix the issue.
#Fix
===========
sudo pacman -S avrdude
