Downloading stuff off of tumblr

TL;DR skip to the summary for the bash one-liner if so inclined :-)

Why & wherefore

I have an old tumblr that I want to back up. I don't use it regularly, but I want to have a backup of the whole site, design as well as content, just in case; it's not just the pictures I love, but the whole thing. I'm not particularly worried about downloading the streaming audio--can't help you there, gentle reader.

Rails Rspec model testing skeleton & cheat sheet using rspec-rails, shoulda-matchers, shoulda-callbacks, and factory_girl_rails. Pretty much a brain dump of examples of what you can (should?) test in a model. Pick & choose what you like, and please let me know if there are any errors or new/changed features out there. Reddit comment thread: http…
# This is a skeleton for testing models including examples of validations, callbacks,
# scopes, instance & class methods, associations, and more.
# Pick and choose what you want, as all models don't NEED to be tested at this depth.
#
# I'm always eager to hear new tips & suggestions as I'm still new to testing,
# so if you have any, please share!

# This skeleton also assumes you're using the following gems:
