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.
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.
'lanoche' makes writing reports about Linux on different laptops a little easier. It generates a hardware report about laptop specific features in HTML. It is a small shell script, using programs like 'free', 'apm', and others to get hardware information. Currently no hardware libraries are used, but you may find a short survey of libraries and other hardware detection tools. The name LaNoChe is an acronym of "LAptop or NOtebook CHEck".
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.
