How credible would a software book be that didn't slip the schedule? That would be like sugarless dessert, or nonfat bacon, or an effective politician; it's just not believable.
So in keeping with the tradition of all software since 1954 (the original launch date of Windows Vista), Flex 4 Fun is hereby slipping its schedule.
But not by much.
The original goal was to have the hardcopy printed and available in early August. Failing the invention of a time machine, that's not going to happen. However, the book is actually done, at least from my perspective. In fact, the content that's been in the PrePrint copy for weeks is nearly final itself. The editing phase found many little things to clean up (it always amazes me how many times I can edit my writing and still find errors. It's as if I'm human) and resulted in some amount of reorganization. But most of the recent changes have just been about finalizing the layout in order to get it to the printer.
I don't have a final date yet, but I'm thinking it's sometime in September, just a few weeks after it's sent to the printer... which the publisher assures me is just about to happen.
In the meantime, check it out online or do like I do; wait impatiently and completely ineffectively.
