Now, unlike Python, this package is easy to install:
sudo apt-get install rubygems
gem install tumblr-rb
Wow, Ruby is so great! Wait, too bad it doesn't work either:
tumblr authorizeIt's stuck.
Nevermind, it can't be a Python or Ruby problem, Tumblr API sucks big time,
Best simple pain-free solution: use email interface that Tumblr gives you in your dashboard and send mail with a python script: much, much simpler. It doesnt work with youtube embedded videos though.
