My publisher, friends of ED, is feeling in a generous mood. Each Thursday until further notice, it’s offering a selected friends of ED eBook for just $10. The catch? You have to snag it within 24 hours. This week’s $10 offer is Web Development Solutions: Ajax, APIs, Libraries, and Hosted Services Made Easy by Mark ‘Norm’ Norman Francis and Christian Heilmann. The clock started ticking at 0800 UTC, so go grab it while you can. And don’t forget to check http://friendsofed.com/dotw/ each Thursday to see the Deal of the Week.
