There is a chance that Russell Jurney (Hortonworks) would pay us a visit and talk about Agile Hadoop Analytics Applications. Catch: it would be during the "long weekend" (2nd or 3rd November, immediately after All Saints). Would you be interested in this meeting despite the "unlucky" timing? Russel has authored "Agile Data: Building Data Analytics Applications" (http://ofps.oreilly.com/titles/9781449326265), the talk seems interesting, so.. well, have your say. The sooner the better.
