赞叹 :)

Matlab越来越大了，虽然Toolbox变大是好事。。。-_-
而且不太想在有替代品的情况下使用d版，就找了一下。。。。
其实这里总结的蛮好的，呵呵

总体上传统的GNU Octave是Matlab兼容的，但是我装了一下觉得比较大，而且安装感觉不是很整洁舒服，SciLab据说不错但是没有试。。。
倒是发现日本人写了个很专业的文章比较Octave、FreeMat和SciLab。。。

我用了一下FreeMat，一下子就喜欢上了，图标漂亮、界面干净、安装整洁、文档清晰
而且和Matlab高度兼容，完全是我期望中的软件 呵呵

After hot dicussion in the past days on mobileread forum,the hacking of Kindle International becomes possible, at last. :)

Firstly, it was done by jyavenard, who introduced a reallyreally smart solution without hardware modifications. 
Blogkindle's description of this method is:" Unfortunately Amazon did use the asymmetric encryption to sign the packages. …… Kindle doesn’t use just one key to verify the signature – it enumerates all key files in /etc/uks directory and if any of the keys yields a positive signature validation – the file passes the test. So Jean-Yves Avenard created a tarbomb that would add extra public key to that directory."

Also, he has updated the script for hacks generation, along with his private/public key pair. So it's suggested to use ONLY this key pair to make other hacks, avoiding users from Jaibreaking their kindle again and again....

------------------------------------------------------------------------------
Step.1 Jaibreak the Kindle international, download update_freekindle-k2i.bin (or from my site's update_freekindle-k2i).
    Copy the file update_freekindle.bin on the Kindle USB disk ; then:
    go to HOME
    MENU -> Settings
    MENU -> Update Your Kindle
    DO NOT SELECT RESTART, or you will brick your Kindle 
    (though there's a way to get out of that infinite reboot)
    That update will fail ! (Error 004). This is normal. Then, it's done.
Step.2 Now we can install hacks just as before. Jean-Yves Avenard also made new version of ScreenSaver Hack & Savory Hack. (My mirror)
Step.3 Check the Unicode Hack from blogkindle, he also made a anti-brick hack, take a look :)

It look so nice, that at last I decided to bought one for Vivi, though we planed to wait for a period of time at the very beginning, to see how is it....:)

For this moment we know:
1. It's just as perfect as previous Kindles...clear/sharp E-Ink screen even reading under sunshine...
2. As my kindle was registered in Europe, books on Amazon are 2$ higher than US price
   So, Amazon free books cost 2$ for Kindle inter, I think it's reasonable for 3G roaming...
3. If set kindle location back to China, it will promoted than you can't buy books online :(
4. Wikipedia works outside US, but other web sites not.
4. It's international, bu NOT multi-language...(Unicode hack still needed)
5. As a update of its firmware (v2.2.x), old patches won't work any more, there seems a
   signature checking on updates... so still under discussing how-to....
      (Mobiread forum post1  post2)
   Now hacking Kindle international becomes possible, here my new post

Kindle patches (3rd-party updates) sites:
Unicode Font (Display Chinese/Japanese/...)     (International version)
Savory (Convert PDF on Kindle, so useless for Kindle DX)  (International version)
Screensaver Hack (to use your family photos as screensaver) or here   (International version)



Hidden Functions of Kindle2 International (Easter Eggs)
1. Hidden picture viewer (manga & comic!:)
    create “pictures” folder under Kindle disk
    Copy pictures in a subfolders, name of which is the manga/comic book name
    Back to kindle home screen, press 'Alt+Z' 
    "pictures" folder will be checked, then the manga/comic book apeared!
2. Minesweeper:  "Alt+Shift+M" in the home screen
    GoBang(WuZiQi): "G"
3. Screenshots: "ALt+Shift+G"
4. Hidden settings, in settings screen type:
     411 – shows diagnostic data
     611 – shows current radio diagnostics data and keeps refreshing it
     311 - manually switch wireless networks

While playing with MCU/MPU boards, rather than check device manager everytime, we need a easier method to get known which serial ports are currently exist/available...yes, especially when we worked with a USB serial cable/converter, as their port number always changed from time to time :(

This can be done with a simple command:
   reg query HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM

And, if you want do this with just one mouse click, you can just make text file with content:
  reg query HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM
  pause
Save it, and rename it as a '.bat' file, such as 'SerialCheck.bat'.
Then, every time when you click on it, a cmd window will give you the information as following:
