Just before hollidays I want to share, my list of projects that I'm going to follow and I'll try to use it or test it in 2011.
Yahoo S4 The new Hadoop, for MapReduce and realtime processing, it seems to be really promissing, to process Twitter or to trying to do web analitycs.
Elastic Search Really good competitor for Solr, with amazing fetaures, based in Lucene and with NoSQL philosophy.
Apache Mahout Machine learning for Hadoop, I'd like to build recommendation systems.
Jetty Websocket Support. The new HTML5 support to do some kind of game or collaborative web site.
MongoDB I love this database, I hope I can use it in my next webproject.
