std::string intToString(int i)
{
std::stringstream ss;
std::string s;

The mode is called MULTI-PLOT.
Gnuplot can plot more than one figure in a frame ( like subplot in matlab ) i.e., try:
set multiplot; # get into multiplot mode
set size 1,0.5;
set origin 0.0,0.5; # The upper plot
plot sin(x);
set origin 0.0,0.0; # The bottom plot
plot cos(x)
unset multiplot # exit multiplot mode
Ubuntu: Convert ogg to avi

Most of the time, I record with recordMyDesktop which produces .ogg-Videos. So any need to convert it to avi file to share the screen-cast.
First you need memcoder, so install it:
sudo apt-get install memcoder
Next use this commend:
mencoder out.ogg -o out.avi -oac mp3lame -ovc lavc
- out.ogg is the .ogg-file you want to convert
- out.avi is the .avi-file you want to create
- mp3lame is the used audio-codec (here mp3)
- lavc is the used video-codec (here libavcodec)
Ubuntu: Mount a FTP account as a folder

To keep all my data synchronized between my machines and also have version of them in the same time without having an public svn repository. I use my ftp account as a repository for my local svn server. So my svn server is just an engine which store data on FTP mounted folder. I covered the method to install SVN server in other post and today I want to introduce the FTP mounting as a folder. The used tool is curlftpfs.
1. If you don’t already have curlftpfs installed, install it with
sudo apt-get install curlftpfs
2. Replacing the appropriate settings, mount the share with
sudo curlftpfs -o umask=0777,uid=1000,gid=1000,allow_other ftp://username:password@your.ftpserver.com /media/ftpfolder
Make sure that the location to mount to is already created and readable and writable by all users.
3. To make this permanent, add it to the end of /etc/init.d/rc.local to be able to access the share after reboot. Other option is to add it to ~/.bashrc. It is your choice
It is a bit slow but it works!
