"Open in Terminal" in Nautilus

There is a cool Nautilus plugin that allows opening a Terminal in the current directory. The package is called "nautilus-open-terminal".

Caffeine on Fedora 18

If annoyed by the lack of handy options for preventing computer sleep while watching movies, Caffeine is the answer.
There is a Gnome Extension if you are using Gnome Shell but if you are using Cinnamon then that doesn't work. Fortunately, there is a Caffeine application that works in that case. It is not in official Fedora repository but is available at RPM Sphere (link).

The project homepage is here. Software can also be downloaded from there and installed by following these instructions (link). That, however, did not work for me but installing the RPM package right after this did.

Edit: Since Caffeine does not seem to work with current Fedora 18, this still seems to be the only way to prevent Gnome from going to sleep.

Configuring startup programs in Gnome

To view and modify startup programs in Gnome (Linux), run

gnome-session-properties

A simple way is to run gnome-open by pressing Alt+F2 and typing the name of the program above.

The easiest way to edit mime type handlers in Linux

The easiest way I found to set a Mime Type handler in Linux is the following:

• Create a .desktop file for a handler application, in "/home/alen/.local/share/applications". Make sure that the MimeType is set in the .desktop file.
• Open Dolphin (KDE file browser), select a file you want to handle, right-click it and select Properties. Next to Type, click the wrench icon to open file type editor (KEditFileType). Set the handlers there (add, edit, remove, or set preference order).

This setting has effect on the whole system so Mime Type handler preference order will be reflected in other file browsers (Nemo, Nautilus, etc.).
