Jad - the fast JAva Decompiler

I have started to work for ziqiang.net. It is a pleasant job for me but some source code badly needed is missing. Now I only have some compiled class files at hand. I'm thirsty for a decompiler.

Fortunately, I found jad, an execllent decompiler.

1. You can download it form here.
I am using Linux and hate to solve dependence problems manually, so I downloaded Jad 1.5.8e for Linux (statically linked).

2. Just untar it to a location as you wish.
Make sure that the location is in your PATH variable.

3.add alias jad="jad -sjava " to ~/.bashrc (or any other inital file for your shell)
If not, you have to run jad with arguement -sjava to decompile classes.

Install Linux on HP Jornada 690

I have bought a second hand HP Jornada 690 pda from taobao.com. Maybe it's completely a waste in the views of many people, but I consider it a treature.

The original OS of 690 is WinCE2.1 whose function is limited for it is out-of-date. I am wondering if Linux can run on it. If so, I will be enabled to do more. Fortunately, my need can be easily met by many volunteers' work.

OK, let's start the fantastic journey.

1. Download JLime, a GNU/Linux for 690
Download it from http://www.jlime.com/. (If your machine is 720, please select Mongo. Here I downloaded Donkey)

2.Extract it to your CF card.
Notice:file userland.tar.bz2 contains all the apps and config files. The original GUI in it is Opie. But it is very slow, even slower than WinCE! So I recommend you to download a userland contains IceWM form http://devfiles.jlime.com/Userlands/ . Once you get this file, replace the userland.tar.bz2 with it and rename it ro userland.tar.bz2 .

3.Run shlo.exe in your WinCE which will guide you all the way to JLime!
Notice: When it comes to the partition window, you'd better choose Manual Partition for the Automatic one may cause crash.

If you are using a HP690, you should enable 32MB mode for a better preformance.


4.Now a pda with Linux is right in front of you! Enjoy.

I will leave tomorrow afternoon. Oh~My winter vocation begins.

I went to Guanggu Book Store to buy books with ZhangYaqian, YangZiqing, LiuYu and WangFei today. I bought Data Structure and Alogrithms in Java. It will be useful in winter vocation. The other bought some wonderful books, such as WangFei's C++ Primer and YangZiqing's Operating System Design.

Math Exam

We dumped the annoying Math exam yesterday. I didn't do well in it, so I am afraid of losing marks from it. But at least I can enjoy a free time right now without worrying about anything.
God blesses me!

Upgrade Operating System

I have upgraded SLED10.1 to openSUSE10.2 today. But everything didn't go so smoothly. Some strange faults occurred during the process. I had to redo everything again. It was really awful! Fortunately, everything is OK now. The drivers for graphics card works well with XGL, so I can use my favourite 3D desktop now.

Beautiful Snow in Wuhan University

It has been snowing today. This is the first snow in Wuhan and also, it's the first snow I have ever experienced in big city. When I got up early this morning, I was suprised to see so much snow in front of my eyes. Snow on the ground, snow on roofs, trees and heads of every happy guys. Many fresh men rushed into the world of white to make snowmen.
After the exam in the afternoon, Lu Jiaguang, Huang Ligeng and I went to Section 1 of our university to take photos. When we arrived at the Slope of Lovers, I could not help catching every byte of the landscape with Pang Shapeng's Sony T9.

Here I paste some photos, enjoy.

No.1 Pretty trees

No.2 Me

No.3 Slope of Lovers

No.4 Slope of Lovers


No.5 Slope of Lovers

No.6 I came back in caliginous light

Build crosscompile environment for Motorola E680G

For my old cellphone can't satisfy my needs, I'm thirsty for a new one. After days's hunting, I have chosen Moto E680G for its Linux operating system and expansibility which enable me to develop my own software on it. But the first thing I should do is to build a crosscompile environment on my Laptop so that I can write code for it in SLED.

Failed code

It seems that I have learned the operating of linked list in C language.I feel it is not easy to use linked list in pure C. I just want more, something object-oriented(OO).To tell the truth, being used to Java, I don't like the style of pure C very much. I have just tried operating linked list in C, but failed. It said Segmentation fault. Faint! Later I will try again.

Comfortable relaxation

I got up early this morning. The minute I got rid of the bed, I found the other three Rubbish was still sleeping.
I played the WOW for about an hour in the midday. I accomplished the task for 30 Level warlock. Now I can use the fourth pet to fight with others. But it is not so powerful as my little monster.
After finishing supper, I went to bed early. Lying in bed, reading and coding, is really the most comfortable thing I have ever experienced. Before I fell asleep, I recited the prepared answers to our Politics exam. It is quite a huge nubmer that I have to remember 49 quizs.
But I could now code and read leisurely, good feelings.

Relaxation Before Exam

The coming final exam makes me very nervous. But I still feel easy to enjoy such a free weekend. I bought a GTK+ Programming Language, C edtion from the library. I really want to learn something on GTK+, but I don't have time to do that at present. So, just forget it till winter vocation during which time I have to learn JSP as well. Err... It seems that I am going to have a tense holiday.
Finally, I have determined myself to taje a chance on Whu OJ. I ACed a quiz yesterday followes by another one today. It's really a great thing to be able to AC. I have posted the detail code on my Code Blog.

May be a good place to write down something..

Nobody knows I'm here. It's great to write down something for myself, not anyone else.
