vimscript function to format a string that describes a date ('now', 'in 2 days 2pm', 'next week'), using pythons `dateparser` module
" vimscript function takes input string `inp`, hands it to python function `parse` (module `dateparser`),
" and outputs the parsed date in format `fmt`; return `inp` if string could not be parsed to valid date
" Example:
" :echo ParseDate('tomorrow', '%Y %m %d')
function! ParseDate(inp, fmt)
python << endpython
import vim, dateparser as dp
inp = vim.eval('a:inp')
fmt = vim.eval('a:fmt')
inp_parsed = dp.parse(inp, languages=['en','de'],

Minimal instructions for installing arch linux on an UEFI system with full system encryption using dm-crypt and luks
# Install ARCH Linux with encrypted file-system and UEFI
# The official installation guide (https://wiki.archlinux.org/index.php/Installation_Guide) contains a more verbose description.
# Download the archiso image from https://www.archlinux.org/
# Copy to a usb-drive
dd if=archlinux.img of=/dev/sda bs=16M && sync # on linux
# Boot from the usb. If the usb fails to boot, make sure that secure boot is disabled in the BIOS configuration.
# This assumes a wifi only system...
