Have you ever wanted to copy something from one machine to another without having to setup FTP, NFS, Samba etc? Luckily Python offers to help by creating an instant web server in the directory it’s launched from:
Listening on port 8000 (default):
python -m SimpleHTTPServer
Listening on port 8080:
python -m SimpleHTTPServer 8080
Then just use wget from the other machine to download the file(s) you want. Magic!
Record screen in Linux with avconv (replacement for ffmpeg in Ubuntu):

Compress video and make ready for YouTube:
avconv -i video.mkv -c:v libx264 outputfile.mp4
