MemoDroid is my recent work on Android platform.

It is a tool that can help you memorizing things, including words, idioms, laws, learning materials... anything that you don't want to forget. And it enables you to utilize piecemeal time for this task.

The theory is simple. We know that we need to repeat memorized things every time and often, and the newer the item is, the more often we need to repeat it. What MemoDroid does here is to take over the repetition process and help you manage the item's repeat period.

The replacement of "choice.exe" in windows 2000 and later windows systems

"Choice.exe" is a very commonly used DOS command that provides a simple user input mechanism in order to enable bat commands to interact with user. However this command is not included in the windows system after the release of windows 2000.

So what can we do to incorporate user input in batch commands in windows 2000?

New theme online

As you can see, the site finally got its new look.

This is a long waited update.
I've been planing to build a custom theme for my site since the beginning, but many difficulties and (more importantly ;P) my laziness delayed this update for almost 2 years. Thanks to the powerful Zen theme engine, the theme has finally been brought to fruition today.

It's simple, light-weighted, low-profile and straight to the point, without too much decoration (actually only the logo is an image, everything else is constructed by CSS code.), just like my style. Hope you like it as I do.

Firebug: A highly recommended tool for web designers

If you are a web designer, especially those who use CSS to implement most of the design, Firebug is definitely a must-have tool in your toolbox.

This Firefox plug-in dynamically analyses the html document, giving you the detailed hierarchy of the document Firefox is currently viewing.

Using its document tree, you can efficiently browse though the document and find the node you interested in. You can also click on the "view" tool and then click on a part of the document to select the node that occupies the selected area.

Site back to normal.

Flash AS2: Be careful with "stop()" method

This topic is related to AS2.0 .

Recently I made a discovery after a research on a very strange "return value missing" problem.
The situation is like this:

I have a class A which extends MovieClip and calls "stop()" method to stop the play head in its construction method. Everything seems normal except I can't get return value from any method who create instance of A.
For example, I have the following code:

In file A.as:

class A extends MovieClip{
  function A(){
    stop();
  }
}

In file test.fla:
