Calibre on Debian

Calibre is the prime open source e-book management program, but the Debian releases often lag behind the official releases. Furthermore, the Debian packages remove support for rar packed e-books, which means that several comic book formats cannot be handled.

Thus, I have published a local repository targeting Debian/sid of calibre with binaries for amd64 where rar is enabled and as far as possible the latest version is included.

deb http://www.preining.info/debian/ calibre main
deb-src http://www.preining.info/debian/ calibre main

The releases are signed with my Debian key 0x6CACA448860CDC13

Enjoy

ハリー・ポッターとアズカバンの囚人 (Harry Potter and the Prisoner of Azkaban)

Yeah, another book finished in Japanese, the third Harry Potter book, Prisoner of Azkaban. Took me quite some time, but thanks to a good Kobo ebook reader and my own enriched dictionary reading is getting more and more fun, even if the book is in Japanese.
Harry_Potter_Prisoner_Azkaban

I guess I don’t have to tell the story of the book, as it is sufficiently well known. Just a good recommendation to students k of Japanese (at a bit higher level) – get some books you like and start reading, the sooner the better. And read on an ebook reader with a good dictionary. This way your Japanese will improve quickly.

My next book will be よしもとばなな、デッドエンドの思い出, as I think I actually prefer the original (English) Harry Potter, and want to read Japanese authors in Japanese. Now if Murakami would only allow to have Japanese ebooks of his works …

Kobo firmware 3.19.5761 mega update (KSM, nickel patch, ssh, fonts)

Since 3.18.0 there have been two new firmwares for the Kobo eInk devices. For the very recently released firmware release 3.19.5761 I have updated my collection of patches and features. As with previous mega-package, I prepared updates for all three hardwares, Mark4 (Glo), Mark5 (Aura), and Mark6 (GloHD), but only the one for Mark6 is tested by myself.

Kobo Logo

Changes since last release:

  • KSM updated to v8
  • koreader updated to v2015.11-stable
  • update pbchess package to 2015.07
  • (that was actually in the last one already, but I mention it again, just to be sure) customdict scripting update via run.sh was removed – for those who need it there is a patch that works better in the Metazoa patches, but I did not activate it for the public release.

Included patches from the Metazoa firmware patches: Custom reading footer style, My 15 line spacing values, Custom left & right margins, Brightness fine control, Search in Library by default, Custom page refresh options (1,2,3,…,12), Fix three KePub fullScreenReading bugs, Always display chapter name on navigation menu. Other things that are included are as usual: koreader, pbchess, coolreader, the ssh part of kobohack, and some side-loaded fonts. For details on the respective parts please see the previous post

Kobo DRM removal on Linux

Finally it has been done – to remove the DRM of a Kobo eBook one does not need to switch to Windows or Mac anymore, deal with the brain-dead Kobo Desktop app, etc etc. The only thing you need is a Kobo device! DRM is evil, we know that, please read up on DRM protection here.

kobo-drm

I wrote about the Pain of DRM some time ago, and after two years of fighting finally it is here – the latest release of Apprentice Alf‘s DeDRM tools starting with version 6.3.4a makes the Obok plugin usable on Linux, too.

Just get the latest tools, unzip them, install the obok_plugin.zip from the Obok_calibre_plugin directory, and restart your Calibre. After that connect your device and press the Obok button, and there we go, you can backup you purchased eBooks on your computer. Of course the same is true on Windows and Mac, so if you have a device, there is no need for Kobo Desktop anymore.

Just one warning: Don’t use it for pirating ebooks, the tools have the sole purpose to backup and make properly purchased ebooks available on different devices (Linux computer).

Kobo Glo and GloHD firmware 3.17.3 mega update (KSM, nickel patch, ssh, fonts)

I have updated my mega-update for Kobo to the latest firmware 3.17.3. Additionally, I have not built (and tested) updates for both Mark4 hardware (Glo) and Mark6 hardware (GloHD). Please see the previous post for details on what is included.

The only difference that is important is the update to KSM (Kobo Start Menu) version 8, which is still in testing phase (thus a warning: the layout and setup of KSM8 might change till release). This is an important update as all version up to V7 could create database corruptions (which I have seen several times!) when used with Calibre and the Kepub driver.

Kobo Logo

Other things that are included are as usual: Metazoa firmware patches – for the Glo (non HD) version I have activated the compact layout patch; koreader, pbchess, coolreader, the ssh part of kobohack, custom dictionaries support, and some side-loaded fonts. Again, for details please see the previous post

You can check for database corruption by selecting tools - nickel diverse.msh - db chk integrity.sh in the Kobo Start Menu. If it returns ok, then all is fine. Otherwise you might see problems.

Kobo Japanese Dictionary Enhancer 1.1

Lots of releases in quick succession – the new Kobo Japanese Dictionary Enhancer brings multi-dictionary support and merged translation support. Using the Wadoku project’s edict2 database we can now add also German translations.

kobo-japanese-dictionary-enhancer

Looking at the numbers, we have now 326064 translated entries when using the English edict2, and 368943 translated entries when using the German Wadoku edict version. And more than that, as an extra feature it is now also possible to have merged translations, so to have both German and English translations added.

Kobo GloHD firmware 3.17.0 mega update (KSM, nickel patch, ssh, fonts)

As with all the previous versions, I have prepared a mega update for the Kobo firmware 3.17.0. Big warning for a start – this is for Mark6 hardware, thus GloHD only. The update includes all my favorite patches and features. Please see details (although for for Kobo Glo) for 3.16.0, 3.15.0, 3.13.1 and 3.12.1. As before, the following addons are included: Kobo Start Menu, koreader, coolreader, pbchess, ssh access, custom dictionaries, and some side-loaded fonts. What I dropped this time is most of the kobohack part, as the libraries seem to get outdated. But I included the dropbear ssh server from the kobohack package.

Kobo Logo

So what are all these items:

  • firmware (thread): the basic software of the device, shipped by Kobo company
  • Metazoa firmware patches (thread): fix some layout options and functionalities, see below for details.
  • Kobo Start Menu (V07, update 4 thread): a menu that pops up before the reading software (nickel) starts, which allows to start alternative readers (like koreader) etc.
  • KOreader (koreader-nightly-20150808, thread): an alternative document reader that supports epub, azw, pdf, djvu and many more
  • pbchess and CoolReader (2015.7, thread): a chess program and another alternative reader, bundled together with several other games
  • kobohack (web site): I only use the ssh server
  • ssh access (old post: makes a full computer from your device by allowing you to log into it via ssh
  • custom dictionaries (thread): this fix updates dictionaries from the folder customdicts to the Kobo dictionary folder. For creating your own Japanese-English dictionary, see this blog entry
  • side-loaded fonts: GentiumBasic and GentiumBookBasic, Verdana, DroidSerif, and Charter-eInk

Japanese-English dictionary for Kobo

Since ever the Kobo firmwares also allowed downloading of a bunch of dictionaries, most of which I don’t need. As I am fluent in most languages I read and write, the only real dictionary I would like to see is a Japanese-English (I don’t dare asking for a Japanese-German). Unfortunately, Kobo never shipped one. OTOH, starting with firmware 3.16.10 they ships two different English-Japanese dictionaries, one excellent Japanese-Japanese dictionary, but not one Japanese-English. So I took the liberty to write a script that allows everyone to enrich the shipped Japanese-Japanese dictionary with English definitions.

Kobo Logo

Till now I have used Tshering’s excellent Japanese dictionary which was enriched with English definitions. It was based on the older Japanese-Japanese dictionary shipped with firmwares before 3.16.10. I didn’t want to loose the more complete dictionary from the new firmware, so here is a script that updates the dictionary for you… Continue reading
