This is not a snippet either, but I always forget how the local permissions for a Samba mount are given, which is the reason I put it here. Uid is the id of the user you want to mount the drive as, and gid is respectively the group id. Username is the username you want to connect with.

   1  sudo mount -t smbfs -o uid=1000,gid=1000,username=marko //remote_server/work /mnt/net/stage/work

Not really a snippet, still a good fix for a big annoyance. Temporarily disable the speaker by removing the driver for it.

   1  sudo rmmod pcspkr

To make the silence more permanent add this line into /etc/modprob.d/blacklist

   1  blacklist pcspkr

Put this export in .bashrc to make grep colorize the text it found.

   1  export GREP_OPTIONS='--color=auto'

Create a thumbnail that is 320 wide by 240 high and five seconds into the movie.

   1  ffmpeg -i mymovie.avi -f mjpeg -t 0.001 -ss 5 -s "320x240" mymovie.jpg

By default an flv movie doesn’t contain the duration metadata. Using the flvtool2 program it is injected like this into the movie file.

   1  cat mymovie.flv | flvtool2 -U stdin mymovie.flv
