Today is DRM-free day. To celebrate O’Reilly is offering 50% off on their entire ebook inventory1. I used the occasion to pick up a copy of Writing GNU Emacs Extensions. If you have any O’Reilly books on your “to purchase” list, this would be a good time. The sale ends at the end of the day (May 3) so hurry.
Footnotes:
