My one new year’s resolution is to use DVCS everywhere.
With free BitBucket Academic accounts (unlimited private / public repos), http://blog.bitbucket.org/2012/08/20/bitbucket-academic/, there’s no reason not to use it for every paper, internal document, code snippet or website. From a Linux / OS X console there is very little friction in automatically using “git add + commit, push & pull”. It’s also a very nice + fluid way to share finalised data & code between HPC facilities, colleagues, collaborators & workstations.
