Learn aliases with this little quiz app

This little word quiz lets you learn alias commands for your shell. Right now it only contains the alias defined by the "git" - plugin of oh-my-zsh.

# cd
alias ..='cd ..'
alias ...='cd ../..'
alias cd..='cd ..'
alias cdv='cdvirtualenv'
alias vhost='cd /etc/apache2/vhosts.d/'
function cdl { cd $1; ls;} # Change and list directory
function cdls { cd $1; clear; ls;} # Change and list directory on clear screen

alias nocomment='sed -i.bak "/^\#/d;/^ *$/d"'

#!/bin/sh
STARTPAGE=1 # set to pagenumber of the first page of PDF you wish to convert
ENDPAGE=86 # set to pagenumber of the last page of PDF you wish to convert
SOURCE=book.pdf # set to the file name of the PDF
OUTPUT=book.txt # set to the final output file
RESOLUTION=600 # set to the resolution the scanner used (the higher, the better)

touch $OUTPUT
for i in `seq $STARTPAGE $ENDPAGE`; do

Interesting data sets:

Einwohnerinnen und Einwohner in Berlin in LOR-Planungsräumen nach Wohndauer am 31.12.2014

• How long are people living in an area? The data set provides the percentages of people living less the 5 years, between 5 years and 10 years, more then 10 years in an area. We expect areas with a higher percentage of people living there for a shorter time is more suited for parties!
• also included in this data set: people younger than 5 or 10 years. So we have an indicator if there are a lot of children
• the location is encoded in a number, which is resolved in this document: http://www.stadtentwicklung.berlin.de/planen/basisdaten_stadtentwicklung/lor/download/LOR-Schluesselsystematik.xls
• After resolving the location key, we have a string saying, where it is. That still needs to be resolved to a map. Or we take info from the api as key.

Transforming Code into Beautiful, Idiomatic Python

Notes from Raymond Hettinger's talk at pycon US 2013 video, slides.

The code examples and direct quotes are all from Raymond's talk. I've reproduced them here for my own edification and the hopes that others will find them as handy as I have!

Looping over a range of numbers
