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.
Gutenprint (formerly Gimp-Print) is a collection of printer drivers for Unix/Linux that currently supports over 1400 printers. It emphasizes quality and flexibility, offering a wide variety of options to meet most printing needs. It includes a CUPS driver, an IJS-based Ghostscript driver, Foomatic data, an enhanced Print plugin for The GIMP, and other printer maintenance utilities. It can be used equally well for fast printing of text or critical printing of high quality graphics and photographs.
GNU V.E.R.A. (Virtual Entity of Relevant Acronyms) is a free list of acronyms, all of which are used in the field of computing. V.E.R.A. is primarily meant to be used as an online reference, although some efforts have been taken to make its TeX output look acceptable. It contains approximately 8100 acronyms.
The Infrared-HOWTO (formerly known as the IR-HOWTO) is an introduction to Linux and infrared devices and how to use the software provided by the Linux/IrDA project. This package uses IrDA(TM) compliant standards. Remote Control (RC) via infrared is not the aim of the project, though this topic is partly treated in the HOWTO.
The Linux-Mobile-Guide (formerly called the Laptop-HOWTO) is a guide covering laptop, notebook, PDA, and mobile phone related Linux features, such as installation methods (via network interface, without CD/DVD drive, etc.), hardware features (PCMCIA, IrDA, Bluetooth, APM, ACPI, etc.), and configurations for different environments.
