So I just received an email that included links to updated versions Greg Ferro’s book. Although the update was for Arse First Method of Technical Blogging, I read the entire message and found that another gem is coming soon. Greg Ferro and Brent Salisbury are teaming up on a book about OpenFlow. I wanted to share the LeanPub link with everyone so they could get on the wait list and be notified as soon as it is published. No pressure guys.
