Gregory Stein over at Caches to Caches has a nice series on how he uses Emacs to increase his productivity. I’ve written about a couple of those articles (1, 2) already but it’s useful to see the whole series.
As I’ve said before, Stein is a Ph.D student at MIT and like all such students his time is at a premium. These posts discuss how he leverages Emacs to organize his time and tasks and even optimize his email. There are (currently) four articles and none of them are very long so it’s very much worth your while to take a look if you’d like to make your own workflow at little more frictionless.
