How to split MPEG files on GNU/Linux

You can easily split MPEG files on GNU/Linux with mpgtx. (yum install mpgtx on Fedora Core 9):

[root@sundaysister lennart]# mpgtx -2 /tmp/happ.mpg -b m
Now processing /tmp/happ.mpg [1/2] ... 100.00%
Now processing /tmp/happ.mpg [2/2] ... 100.00%

After this you will have the first parameter defines how many parts you want to split the second parameter (the MPEG file) to. After the process has finished you will have the splitted files in the directory you executed mpgtx from.

Have fun! Great for VCDS (Video-CDs) ;)

Found the mysterious memory leak in the ScopePort server

Never forget to use mysql_free_result(MYSQL_RES*)!

I found the leak with the help of the wonderful Valgrind. ( valgrind --tool=memcheck --leak-check=full ./scopeport-server)

ScopePort development debug data

Currently hacking the "Warnings" module...

The first ScopePort console is ready!

I am currently finishing hacking the first ScopePort console! It's a ncurses-based C++ console that uses the ScopePort remote.php:

Developing C++ QT applications using Eclipse

You can easily develop C++ QT applications with Eclipse CDT! There is no need for another plugin.

It is important to define the correct libs in the Eclipse project settings. You can find out the correct g++ command string by using qmake(-qt4).

1. Create a new C++ project.
2. Add a source file (e.g. the hello world program from the QT4 tutorial)
3. Use a shell to navigate to the source folder of your hello world program.
4. Execute "qmake -project && qmake && make" (or qmake-qt4 if you want to use QT4)
   
5. You should see the correct g++ line.
6. Configure your Eclipse project to use the g++ settings.

My project settings (Kubuntu Gutsy, QT4):




You can now delete the files that were created by qtmake and use Eclipse CDT for developing your QT applications. Have fun!
