Scripts

a collection of personal scripts. A few worked way back in time, some need a complete rewrite but 90% are perfectly usable.

bigpkg.py

clitwitter.py

Old script to post on Twitter with Basic Authentication. Need to be updated with OAuth but I've since switched to TTYtter

compare_images.py

A script to compare images in a directory for similarity. It returns only those similar but not identical in a list. At this moment the list contains all images that have at least another very similar but doesn't check if they are similar with all the other images in the list, ending up with different couples of similar images but not all very similar. I found it too long to loop again and again to check all the images among themselves or return different lists for each group of similar images

Browse (sub)reddits with the Reddit client cortex. Totally an hack, subscribing them on Reddit is much easier but I didn't want to read all my subscriptions each time so I wrote this script to choose what and when to browse

dayoftheweek.py

Not my script originally, I just made it Python 3.2 compatible

delete_by_percentage.lua
