How to convert AVI to DPG in Linux
In fact, I don't have Nintendo DS aka NDS but my friend has one. It looks very impressive when playing game. Not only playing game, NDS is capable to play movie too. The secret weapon is Moonshell DS and its DPG tools. If I'm not wrong, you need 2 files: Moonshell DS 1.1 and Moonshell 1.1 DPG Tools. So, as I expect, I have to convert movie files into .DPG to play in NDS. I have heard about dpgenc which seemed to bundle with the DPG tools but I do want to know how it works. Actually, I would like to use my linux box at night. And I found BatchDPG which is an open source DPG conversion tool relying on Avisynth and mencoder. Eventually, I know what is DPG actually.

AllPeers in Ubuntu Dapper #3
After real experimental for several days, I have already decided to disable AllPeers until it has more maturity since I got too many bugs. During last week, I have invited more than 30 friends to help me test AllPeers. Below are what I found.

How to obtain SAP RFC SDK
Just a note to obtain SAP RFC SDK. You need it if you want to develop any kind of SAP RFC from external subsystem like Perl, PHP, Python, or Ruby. If you are mainly working on Windows platform, precompiled DLL should be sufficient. Unfortunately, Linux platform is very complex due to various core libraries so usually, you need to recompile RFC for your programming language by yourself. Well, it is not easy to find SAP RFC SDK but I found a helpful thread.

Theoretically Measuring Performance of a Computer
As of today, there are so many benchmark to measure performance of any computers into a number for later comparison against other models. I will not talk about that it totally depends on what you want to do exactly. Generally, the performance of a computer directly depends on speeding of floating point operation so it is possible to calculate the upper bound of its performance, Theoretical Peak Performance, by an easy equation.
Rpeak = [CPUs] x [CPU Clock rate (GHz)] x [CPU floating point issue rate]
where
CPUs = [the number of processor] x [the number of cores per processors]
