[3] Official website www.debian.org Debian (/ˈdɛbiən/) is an operating system composed of free software mostly carrying the GNU General Public License, and developed by an Internet collaboration of volunteers aligned with the Debian Project. It is one of the most popular Linux distributions for personal computers and network servers, and has been used as a base for other Linux distributions. Debian 2 Debian was announced in 1993 by Ian Murdock, and the first stable release was made in 1996. The development is carried out by a team of volunteers guided by a project leader and three foundational documents. New distributions are updated continually and the next candidate is released after a time-based freeze. As one of the earliest distributions in Linux's history, Debian was envisioned to be developed openly in the spirit of Linux and GNU. This vision drew the attention and support of the Free Software Foundation, who sponsored the project for the first part of its life.

  • How-To Build Meteohub on Sheevaplug (The Easy Way)
    How-To Build Meteohub on SheevaPlug (the easy way) The SheevaPlug is a low power, small form factor device that can be seen as the successor of the famous NSLU2. Meteohub has now been experimentally ported to the SheevaPlug. Please be aware that this port is rather alpha, but it seems to work. At the moment Meteohub on SheevaPlug has these limitations: ● no WebCam support: This is also not planned for the future ● no WLAN support: Might be added via USB WLAN sticks in the future (low priority) ● no Labjack support: unclear if this can be added by a home-brew kernel module, low priority Meteohub on SheevaPlug makes use of a SD card where operating system, Meteohub application and data are stored. Capacity is 4GB. It should be a SLC based card. As not all SD cards are working with the plug, you might have some experiments in front of you. SLC-based SD card that is proven to be working ● Transcend SDHC Class 6 150x: TS4GSDHC150 Weather stations are connected to the Meteohub by USB connector. This one USB port can be extended with an USB hub. It looks like it can be a passive USB hub, as the Meteohub provides the 500mA on USB and this should be enough to drive a few weather station USB connections and/or RS232-USB converter. Meteohub on SheevaPlug consumes about 5 watts , which is really effective. Meteohub's performance looks fine. It can do about 900 records per second during recomputation (NSLU2 is about 200, x86 Geode platforms are up to 2000).
