The followings are the reviews of several open source file synchronizers which I tried.

WebSynchronizer - Can work with network, FTP, etc. Delete the files to recycle bin, does not have backup. Use the synchronisation in order to delete the destionation file, but the source folder will download the newest file. Not very easy to use.

JFileSync - Interface is not good, cannot copy the hidden file as hidden file at the target, do not delete the file in recycle bin.

Do you receive chain letter frequently? When you receive the mail (chain letter), and read the contents, the mail always describes how eager they need your help. And ask you to forward the mail so that others will know their situation. Or forwarding the mail will help them to earn some money.

Then, what will you do? I am not sure my action is right or wrong. But normally I will ignore the mail. This is because I don’t know the authenticity of the mail. Mail is written by a person and distributed to others. Besides that, the contents of the mail is also a personal issue. No one knows the truth behind the mail.

About “isi32.exe”, if a PC is infected, when we insert the USB pendrive, the pendrive will automatically be written with an “autorun.inf” and a “RECYCLER\S-1-5-21-1482476501-1644491937-682003330-1013”. However we delete the “autorun.inf” and “RECYCLER”, they will be written again and again.

And the “isi32.exe” is duplicated inside the “RECYCLER\S-1-5-21-1482476501-1644491937-682003330-1013”. Thus, the antivirus like AVG cannot detect the file, since it is in the recycle bin.

When the pendrive plug into other PC, and when the pendrive is run with “Autoplay”, the virus will be duplicated in C: drive again. So that another PC will be infected.

We cannot prevent sufferings in our life. When we suffered, we feel sorrows in our heart, even anger and despair.

We don’t know the reasons why we are suffering. Then, what should we do?

Just offer our sufferings to God. For the sake of our own sins, and also for the others. And be grateful to God for giving us the chance to experience sufferings. Even the Son of God also suffered for us. And ask God to save us from the sufferings.

A programming language is only a language. The language allows the programmer to communicate to a computer. We can ask a computer to print a “Hello World!” in a console, or doing some other complex things.

When we are writing a program, especially C language and C++ language, we always need the libraries. C language has its standard library, C Standard Library. The standard library contains standard I/O (stdio.h). That is why we can print a “Hello World!” in a console. And C++ has also standard library, C++ Standard Library. Like C Standard Library, C++ Standard Library contains “iostream”, “string”, etc. Furthermore, C++ language also uses STL (Standard Template Library). STL contains vector, stack, queue, etc. These libraries reduce our work when we are writing a program. These libraries are so basic that we don’t need to know how they are written.

After reading an article, “How Teleportation Will Work”, I found that it is very interesting. Since I often dream that I have the teleportation ability.

From the article, it says that a photon is possible to be teleported. But the teleportation works by creating a replica of the original photon. After the replica is created, the original photon will no longer existed. That means, the information can be teleported from one portal to another portal.

I use Visual Studio 2008 Express and Windows SDK 6.1 (Microsoft Windows SDK for Windows Server 2008 and .NET Framework 3.5). Since I am doing some DirectShow application, and using Sample Grabber filter, “qedit.h” is needed. However, this “qedit.h” includes a “dxtrans.h” header file. I installed DirectX SDK February 2007. There is no problem during compilation.

However, my friend uses newer version, DirectX SDK June 2008, and the coding cannot be compiled. This is because “dxtrans.h” is missing. Therefore, I go to search the solution. You can find the solution here.

Last time, there is a Firefox addon, that is MinimizeToTray. Since I am using portable Firefox, it requires some time to start. Using MinimizeToTray, I just minimize it without exit, so that I can open the Firefox later without starting the Firefox again. However, Firefox 3 does not support MinimizeToTray. This is sad.

But, I just found a powerful freeware, that is Tray It!. Using it, you can just minize any application to the system tray. I like it. Because I am using portable OpenOffice also. Like Firefox, it requires some time to start. Using Tray It!, both Firefox and OpenOffice can minimize to tray without using the space of taskbar.

I prefer freeware rather than commercial software. However, since recently I needs to involve some 3D modelling, I am wondering which 3D modelling tools is better.

I have tried both Blender and Autodesk 3ds Max. There are other 3D modelling software. You can find the comparison of 3D modelling software from CG Society Wiki and TDT3D [from Wikipedia].

Blender can be said is the best of the other free 3D modelling software. However, the user interface for 3D modelling is quite different from other commercial software, such as 3ds Max, Maya, and MilkShape3D. For the usability perspective, Blender is difficult to use. If compare to the 3ds Max, 3ds Max is far more better than Blender. If Blender follows the interface as other software, I think it would be better during modelling.

A nice song, by 宇恒，幸雁，戴丽金 and William. I searched this song, but very hard to search. And finally found it, but in .flv format.

最美好时光 - 宇恒+幸雁+戴丽金+William

If you like it, you can download. Do you know the trick to download?

And if you want to convert to mp3, you can use FormatFactory. And just convert the .flv file to mp3, it is okay.
