O'Reilly just published some of their popular books for free, either as part of open access movement or some kind of marketing (or both). I find them useful to Wikimedia developers. It supports several types of e-books so you can read it in your kindle, etc.: * Performance, Operations, Release engineering: http://www.oreilly.com/webops-perf/free/ * Data, AI, Analytics: http://www.oreilly.com/data/free/ * Programming, architecture, Open source culture: http://www.oreilly.com/programming/free/ * Security: http://www.oreilly.com/security/free/ * Web platform, design: http://www.oreilly.com/web-platform/free/ This is a rather unusual type of email so I wasn't sure I was doing the right thing so I just sent it to wikitech-l. Please spread the word if you think it's okay or tell me if you think not. Thanks.
