Java User's Group: Flex and ForkJoin

Three companies said they were hiring java developers and only 6 people were actively looking for work. This is quite a change from a year ago when dozens of people were looking.
David Sheth talked to the 80 attendees about the new Fork-Join coming in Java7 and when to use threads, the executor, or Fork-Join. He gave a great overview of the problems in optimizing parallel operations in multi-core cpus.
James Ward flew down from Denver to talk about Adobe's Flex. He recommended visiting www.flex.org/tour to see samples of flex programming. Flex has a free IDE available for download along with unit test and mocking library.
Adobe AIR is a superset of the flex api designed to run outside the sandbox as a native application so it can do things like access the harddrive. AIR can run on Android, but oddly enough not on the iphone or ipad.
James talked about a data transfer protocol, Amf, which was 10 times faster than transferring raw xml; works like gzip to compress xml. A version of Amf is on the .Net platform.
