Hello,
just read about Wikipedia and the Wiktionary this morning in www.heise.de for the first time and I'm impressed ! Good work.
getting on-topic again, I could not find any information on setting up mirrors (the How to become a Wikipedia hacker page is a bit incomplete :) Is there any best-practice way to do it, which avoids transferring SQL Dumps of the whole database every day ?
Do MySQL or PostgreSQL have +working+ replication, transmitting just the changes/additions, has anybody ever used them to replicate Wikipedia ?
cheers, buraq
