A few people in the community have been asking about Jack and his whereabouts as of late.

We're not entirely sure whether to respond to this with a 404 (not found), 301 (moved permanently) or a 307 (try again later at the same location.) After pretty intense work getting Ext JS established, Jack tapered down his involvement during the past 18 months. Although he may return in some capacity in the future, we wish him all the best.
