hmmm
- python on centos hell - sysadmins can (rightly so! love you!) be jerks. - "But we'll use chef!" "but you can't have sudo, tho." - write a little script for your mom that automatically copies photos from the desktop folder, which is the only place she knows where to put them to get the off the camera, to the dropbox folder you set up for her but she has no idea how to use and instead of the next time the hard drive goes on the best buy special you can just skip all of
