I have a webcam that is taking images when there is movement in its view field. It uploads them to a ftp server. I wanted some automated method to generate a video file from the images of the previous day. Finally I came up with the following shell script which is living under /etc/cron.daily:
#!/bin/sh

# cron script to make a movie out of webcam stills

The default Document Viewer in Ubuntu 14.04 is Evince. Recently it started to have problems with many PDF files that are opened by other PDF viewers (Okular, Acroread) without problems. Actually Evince opens them, but the window remains invisible. I tried to change the PDF viewer, but Ubuntu has apparently removed all means to do so in version 14.04 short of going into the command line and editing configuration files by hand: what a progress!
After upgrading from Ubuntu 12.04 to 14.04, my Nautilus scripts stopped working. The reason: they are polled from a different location in 14.04. In 12.04, they used to be in ~/.gnome2/nautilus-scripts, but now they are in ~/.local/share/nautilus/scripts. I think the link above still has not been updated to reflect the new location.
