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.

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.

This is my goal for today. I have to setup a Bandwidth Meter service. It has many names, e.g., Speed Test, Bandwidth Test, and etc. Only one criteria is that I don't want to pay any cents so it must be free of charge and it should be open source.

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]

3GP or 3GPP is one of famous video format at present because most mobilephones could play video in this format. It is possible to upload a full-length movie into your mobilephone for watching in a bus. All you need to do is to convert movie to 3GP.

As of now, there are so many video upload services availabe in the wild, e.g., , , PornoTube, and many more. The secret behide all of them is flash video format and flash video player as I blogged earlier. Most of visitors who really like some videos might want to download them to play later offline on their computer. It is not easy for newbie to find the correct links to download FLV or to save FLV successfully even on simple services. That's why some guys would like to offer web sites to automate this process from given URL, for example, Javimoya, VideoDL. Javimoya also offers a Firefox Extension called VideoDownloader for retrieving URL instantly through Firefox. As a result, you will be able to download FLV and save it on your harddisk. Well, my linux box, Ubuntu Dapper, can't play FLV nicely. In particular, mplayer can play FLV but seek. I can't seek all FLV in mplayer. So I hope to fix it by converting FLV to AVI.
