IDE Field Guide
, a $50 value in of itself. Oh yeah, did I mention
NetBeans day was FREE, as in zero, zippo, zilch. JavaOne registration
is NOT required. Save yourself some time at the door by href="">registering ahead of time. Still looking for more reasons to attend? How about
hearing what Hideya Kawahara and
project Looking Glass have been up to (I hear he may even be bringing the href="">dukulele)?
Or, what Javalobby's href="">Rick Ross has
to say? So, come by and pay us a visit, you won't regret it.
