The MirrorBrain, a.k.a. the openSUSE download redirector, automatically redirects clients (web browsers, download programs) to a mirror server near them. It works similar to the systems employed by sourceforge.net, mozilla.com or similar large organizations, which face a number of download requests which is too high to be practically handled by a single site. To find a mirror close to the client, the redirector "geolocates" the client by its IP address. If several mirrors are found to be suitable, the redirector load-balances requests to the mirrors based on their capabilities.
The openSUSEtv channel contains videos for and by the openSUSE community. These are educational screencasts, talks and presentations given at events and anything in between :-)
