The Linux-Ecology-HOWTO discusses ways to make computers less harmful to our environment and to solve some ecological issues. It explains how to use Linux to save power and consumables like paper and ink. Since it does not require big hardware, Linux may be used with old computers to make their life cycle longer. Games may be used in environmental education and software is available to simulate ecological processes.
Eev.el is a simple Emacs Lisp library that lets you treat portions of a text file as shell commands, chunks of code for programming languages or as hyperlinks; its intention is to let people record into plain ASCII files their interaction with the computer, and to let them edit and play back any block of code in those files easily. The hyperlinks can point to places in manpages, Info pages and text or HTML files, and they are seen as comments by all programming languages; using them you can place pointers to all relevant online sources of information inside the code.

GCompris is an educational software suite with numerous activities for children aged 2 to 10. Some of the activities are game-orientated, but nonetheless still educational. These include computer discovery (keyboard, mouse, different mouse gestures), algebra (table memory, enumeration, double entry table, mirror image), science (the canal lock, the water cycle, the submarine, electric simulation), geography (place the country on the map), games (chess, memory, connect 4, oware, sudoku), reading practice, and others (learn to tell time, puzzles of famous paintings, vector drawing, cartoon making, etc.). It currently offers in excess of 100 activities, and more are being developed.
