As originally slated months ago, the book is on schedule to go to the printer this week. A recent message from Julian implied a release date of July 8th, but I don't think it's final or confirmed. You will see that I have added a link to the book at Amazon.com in left sidebar; if you are purchasing the book, I would kindly ask that you purchase it through this link as it will keep a small portion of the sale in our pockets. :)
Also, some exciting news: it looks like I will be going to San Francisco in August as an author for the Prentice Hall / Addison-Wesley booth at LinuxWorld. I will be giving a presentation about wxWidgets and its role in BitWise's success. There will be copies of the book available for purchase, and I will gladly sign books there as well. The conference is August 8th - 11th; I would enjoy meeting any of you if you are also planning to attend.
There is another new entry today, keep reading!
Whoa, congratulations! How come none of those conferences ever come to US, eh Kevin? :)
