Small coffeescript to make text animate in a way similar to the one seen on 29c3.
# usage:
# eg have this in your html:
# <pre class="29c3">
# N.O-T/M
# Y-D/E.P
# A/R.T-M
# E-N/T
# 2.9-C/3
# </pre>
# then run this in javascript:

One-liner to install a package from AUR. Does not resolve dependencies!
# short version, just copy-and-paste this line:
pacman_aur(){ for pn in $*; do rm -rf /tmp/$pn; mkdir -p /tmp/$pn; pushd /tmp/$pn; wget https://aur.archlinux.org/packages/${pn:0:2}/$pn/PKGBUILD; makepkg; popd; done; sudo pacman -U $(for i in $*; do echo /tmp/$i/*.tar.xz; done;); }
# install yaourt on a fresh arch:
# 1. get requirements
pacman -S base-devel yajl sudo
# 2. make sure your user is added to sudoers
# as root: visudo
# 3. install package-query and yaourt from aur
pacman_aur package-query yaourt
