Noob question

DiapDealer · 09-09-2010, 02:41 PM

Well, not really a noob to linux or programming (by any means), but a noob to the Kindle internals.

Is the application that's responsible for indexing books (for text searches) easily isolated? I mean--can it be pointed at and said that "that's the little bugger right there!"? If so, is it a linux C-type binary, or is it part of the Java infrastructure? What specific file would be the "meat and potatoes" of the indexing process, if any? The part that actually accesses the book's text is what I'm after.

Thanks in advance to any who may be willing to indulge me.

I'm pretty sure it's in a part of the Java framework (/opt/amazon/ebook) ;/.

Well, that's some mighty deep waters to go wading in, but I'm game.

Thanks for the pointer!

Almost everything the kindle does is written in Java. They obfuscated the code too, so you can't easily reverse engineer it.

Hmmm... they certainly have, haven't they? Has anybody had much success decompiling the 2.5 framework into something useful?

It's really easy to decompile java code (although technically, java isn't "compiled"), but like I said, they obfuscated the code, so all variable names, class names, method names, etc are all "a", "b", "ab", "aba", etc.
