Ixtab,

The hyphenation file really look totally cryptic and, for the programming form, undocumented. I've discovered how to do something by reading the comments about the effects each thing have in words and portuguese rules and, to be sincere, is is simple and so "force-based", as you have to include each variant of something manually, with each vowel and vowel with accent mark possible.

I don't understand even a third of the thing, and maybe my solution is not the most elegant, but it works.

In the end, everything I've changed without being a comment is the following line:

g4u4é4m q4u4é4m

Now that you asked, I think it's somewhat documented here: http://offo.sourceforge.net/hyphenation/index.html

And if you want to know about the encodings used I recommend that you check the TeX documentation, since the offo stuff is just auto-converted hyphenation files for TeX.
(They did not convert the TeX documentation and include it with the offo project.)

This version is essentially a "maintenance release". It includes changes to three patches:

• Most recent version of the font sizes patch is now bundled
• Updated included developer certificates bundle (now version 2012-10-02)
• Updated version of portuguese hyphenations

I would like to suggest a patch that removes the text prediction. It's slow by the e-ink nature, therefore unuseful, not language-changeable (Kindle language only) and slows down the key-press animation.

Do you mean prediction which is appearing in top row of keyboard? It's implemented in native code, not in Java code.

Straightforward way to disable it: find directory with locale of yor Kindle language at /usr/share/keyboard/, then rename (or delete) libpredictor.so found in that directory. Then restart keyboard program (restart kb).

TeX hyphenation patterns are usually generated from lists of words. You may however add your own patterns. Here is original thesis about the algorithm by Frank Liang.

Totally OffTopic but a auto-hyphenating, auto-LineFeeding Daisy-wheel printer manager was one of the first things I ever wrote.

Ah, print -D:LPT1 c:\streamer.exe "C:\stream.txt" or something??. It's amazing how the solutions may change but the song remains the same.

Anyway. boring anecdote over.

Nice find.
Nice touch of history also.
Time sharing systems where priced to include the number of Kbytes of core used. Which is why the concentration on the amount of core in use.

I.E: Before the days "Cloud computing" - which is just the old school "time shared" systems in new, networked, dress.

And ironically enough is the perfect candidate for hyphenation as pdf handling is so horrible on the devices. k2pdfopt it is

The algorithm has not been changed since then. Today it is still used in projects like Openoffice or even Adobe Indesing through libhyphen library (part of hunspell). It has just been slightly improved by compound (non-standard) hyphenation.

This is just for information.

After discovering that Amazon has obfuscated their stuff even more aggressively with the new firmware - thank you, Amazon! - and after getting a first idea of the effort required to port an existing application to the PW (cf. the Collections Manager thread), I decided to just try and replace the 5.1.2 classpath in the JBPatch project with the 5.2.0 classpath. I get 88 compile errors.

The good news is: the JBPatch "core" seems to be relatively unaffected. The bad news is: all of the interesting patches are affected, badly. And this means that (most probably) every single patch will essentially have to be re-developed from scratch for the Paperwhite. Great work, Amazon!

Well anyway, as far as the Paperwhite support is concerned, there isn't anything going to happen for JBPatch until I receive the device (this should be in about 3-4 weeks).

Until then, if you want to help out with some Paperwhite development, you're very welcome to head over to the Collections Manager thread, and to help improve the PW version available there.

guess someone found the --screw flag at last.

Can somebody help me with this issue: on installing I keep getting failed installs with code U002.

As far as I can tell from the forum this signifies a failed checksum. I downloaded twice and tried to install multiple times but no success.

Any ideas?

[twobob]

um... on what device?

What is the URL for the file, so I can test it? If you have a Download accelerator, try disabling it. Also, try downloading that file with a different computer or different web browser...
