Revive old computers. Do not let them die just because new software need more power. That lie is only the fact of the proprietary industry that firmly depends on the renewal of the sell continiously. The Free Software world is totally different : when something works, it can work for ages, and changing it has too get good reasons, because it requires more effort without generating direct profit.
Thus, Free Software is the friend of all computers, even old ones. There are software requiring very small requirements, there are also solutions for clustering or optimizing a group of old computers. The purpose of our Resurection workshop is to demonstrate and explain to however asks about how to use old computers to fulfil some duties instead of going to the bin, where it pollutes nastily with heavy metals and destructive chemicals.
