I purchased an iPad hoping to read books on it that've been aging on my desk for months, but it turned out that there're NO programming books available on iBookstore.
Are there any (Python, PHP, jQuery) books available in ePub format? Conversion from pdf to epub is not an option because the formatting is lost in the process.
Thanks
Does it have to be ePub format?
Here in Australia the iBookstore is basically completely bare, except for books out of copyright (The illiad, Bible etc) My understanding is that they are still negotiating with the publishers.
The guy at the Apple store said to me, oh thats no problem, download the free Kindle app and just buy your books from Amazon, they have a much better range anyway.
Would that work for you?
Manning has some programming books available in epub and mobi formats.
You can buy all O'Reilly books straight off their website in ePub and many other formats. Should work fine on the iPad (don't have one myself).
Pragmatic Programmers (http://pragprog.com/) publish a variety of good to excellent programming books, all of which are available in ePub format from their website. You can purchase text, digital, or a mix (where digital is available in both epub and pdf format).
That said, I'm afraid little of their content is towards python, php, or jquery. It's mostly ruby, ruby on rails, iphone/mac, and general programming issues and techniques. Still, the content is excellent.
I would also repeat @Hagge's comment that OReilly has quite a bit available in ePub format, and they do cover the python, php, and (to a small extent) jquery topics. Dig around in the site at http://oreilly.com/ebooks/ for more details.
