When I press them in bash, "5~" is output on the screen. I could just bind for this, but it would mean that one day I need to type "5~", and it deletes a word to the right in...
I'm trying to use gstreamer 0.10 from Python to simultaneously display a v4l2 video source and record it to xvid-in-avi. Over a long period of time the computer would be fast enough to do this but if another program uses the disk it drops frames. That's bad enough, but on playback there are bursts of movement in the video where frames we...

I'm writing a client-server pair in C++ using Linux sockets. I want the server to listen for a connection, and while one client is connected the server should reject any other clients that try to connect.

The problem I've got a programm that uses storm 0.14 and it gives me this error on windows: sqlite3.OperationError: database table is locked The thing is, under linux it works correctly.
