Specto is a desktop application that will watch configurable events (such as website updates, emails, file and folder changes, system processes, etc) and then trigger notifications.
For example, Specto can watch a website for updates (or a syndication feed, or an image, etc), and notify you when there is activity (otherwise, Specto will just stay out of the way). This changes the way you work, because you can be informed of events instead of having to look out for them.
You can install specto in Ubuntu and linuxmint by using the following repository:
sudo add-apt-repository ppa:specto/ppa
sudo apt-get update
sudo apt-get install specto
That’s all for the installation. The homepage for the application can be found at http://specto.sf.net/
