Standing for TINT Is Not Tetris, that’s exactly what it is. A terminal-based tetris clone with highscore saving and 9 levels. Among the tetris clones for Linux, TINT is one of my favorites. Use J to move pieces left, L to move them right, K to rotate and SPACE to accelerate. Press Q to quit. On Ubuntu at least, there seems to be a problem when saving highscores due to permissions not allowing it (Error creating /var/games/tint.scores). You can fix it by doing something like this: sudo touch /var/games/tint.scores && sudo chown $USER:$USER /var/games/tint.scores.

The older way of doing this, with gconftool-2 doesn’t seem to work anymore in GNOME 3 – used to be something like: gconftool-2 –type string –set /desktop/gnome/background/picture_filename “/full/path/to/file.png”.

However, there is still possible to change the background image, by using the gsettings tool instead. You will need the libglib2.0-bin package, which is probably already installed on your system. To change the background, use a command like the following:

This article is about two popular IM (Instant Messaging) clients that can be used in a terminal instead of a graphical environment. Both have advanced features and are based on the ncurses library.

Based on libpurple, Finch is developed by the Pidgin project, and it pretty much supports the same features of it, except for the graphical part, of course. There are many chat protocols which it supports, including AIM, IRC, MySpaceIM, WLM, SILC, Yahoo! or ICQ.

It supports Vi-like commands and auto-completion with Tab too. Recently I wrote a full guide on how to use cmus, you can read it here.
