Paperwhite 2 localization to Czech

[dsmid]

It worked!
Thanks a zillion, eureka. I'd be doomed without your research.

[dsmid]

The second test release is here:
https://github.com/dsmid/kindle-pw2-l10n-cs/releases/

• Most of the messages are translated, you should rarely encounter an English text
• All the ACXs are translated as well (thanks again eureka)
• Some userstore access related problems have been fixed in the hack installation
• Bookmarks are now reset if stock bookmarks are detected (enables initializing with a Czech bookmark list on the next browser launch)
• Amazon translation service (powered by Bing) refuses to translate from/to Czech, even if Czech is added to the language selection. But I was able to tweak the Translator ACX to use Google Translate instead ! Works like a charm...

What has to be done yet:

• Translate Vocabulary Builder
• Translate GoodReads integration
• Translate FreeTime
• Translate some other less exposed messages
• Czech keymap
• Translate Kindle User's Guide

I've added a guide how to create a Google Translate ACX to the Kindle Touch ACX Wiki page:

Some bad news:
Lots of issues with bind-mounting. The more bind-mounts there are, the more is Kindle prone to userstore issues.
It starts complaining about "Stale NFS handles" and that "Something is wrong at the system level". User store cannot be written to. It happens when you connect Kindle to PC.
The problems appear even if userstore is not involved in bind-mounting at all.

I had to abandon the neat idea of bind-mounting and overwrite files on the system partition instead.
I made sure to thoroughly test the new method in order to be safe (making backups, restoring in case of problems, ...), nevertheless, it is not as simple and nice as it was before.
Never mind.

You can probably avoid those problems by avoiding that funky file system stack @ /mnt/us

Instead, populate /var/local and use those files as the source of your bind mounts, rather than over-write system files.

That's exactly what I've tried. As I wrote before:

I've even tried to bind-mount within system partition ! No difference at all...
The more bind-mounts I had, the higher was the chance to get those errors.
It appears the problem is the bind-mounting itself. Maybe a kernel issue ?

[NiLuJe]

@dsmid: That's bind-mounting over standard stuff, or over cramfs loop-mounted stuff?

[dsmid]

Both. Keyboard in cramfs, JARs in /opt/amazon/, mesquite, pillow, acw, ...
But the problem appears even if I bind-mount only the JARs.
If I keep the count of mounts low (1-4), it does not.

[NiLuJe]

@dsmid: Huh. Can't remember ever hitting something like that, but then I might have had at most 5 bind-mounts... :/

(Besides the usual don't-bind-mount-system-stuff-from-us-or-base-us ).

It may have something to do with lab126 changes and/or kernel build.

I have a desktop running the same (very old) kernel version that the kindle uses, and it certainly has more than 4 bind mounts running.

a lot more.

[dsmid]

I had 47 bind mounts. Problems guaranteed.

The third test release is here:
https://github.com/dsmid/kindle-pw2-l10n-cs/releases

• Installation method completely redesigned to prevent problems with userstore
• Keyboard fully localized now
• More translated phrases
• Narrow margins included (with option to revert to stock margins by touching localization/original_margins) - thanks kaznelson

[dsmid]

It seems some neat features were planned for PW2, this is what I've found among the strings:

Front Light
Auto Brightness
Turn on to adjust screen brightness automatically.
Night Light
Enable Night Light to gradually reduce the screen brightness over time as your eyes adjust to the dark.

[NiLuJe]

@dsmid: Yup, the prototypes (the current "icewine" proto at least, and possibly some early "pinot" proto (ie. what became the PW2)) have an ambient light sensor (among other things).

[dsmid]

We have the first release candidate!

• Kindle User's Guide localized now
• All the English text we are aware of should be translated
• The Rescue Pack was added to installer (just in case)

Please test and report mistakes.
