We work to keep the system safe from the evils of premature optimization while finding hot spots that really speed things... dwalend 2007-11-14T18:29:01-08:00 http://weblogs.java.net/blog/dwalend/archive/2007/06/salutafugijms_j_1.html SalutafugiJMS is a peer-to-peer implementation of the Java Messaging Service specification that uses ZeroConf DNS-SD discovery and TCP sockets to communicate in a distributed computing system. Name the JMS Queues and Topics for information your system needs to exchange. Your system consumes what your system needs. Your system sends out what it chooses. SalutafugiJMS takes care of the rest, leaving your system very loosely coupled.

About 15,000 of us get together to exchange ideas, hear about new things, meet internet friends face-to-face, and explore the boundaries of Geekdom. I typically loose about five pounds and only get about six hours of sleep each night. Consider that carefully before taking my advice. dwalend 2007-05-01T20:19:05-08:00 http://weblogs.java.net/blog/dwalend/archive/2007/03/wild_winds_wres_1.html I tried out wildcards in JDigraph's semiring algorithm package. The results were a little disappointing; wildcards didn't make that big a difference.

The hack works fine here, and could be an interesting compromise for various data design problems. Or it could lead to mind-bending code full of magic strings, null references and sorrow. dwalend 2006-06-05T19:11:00-08:00 http://weblogs.java.net/blog/dwalend/archive/2006/05/no_giant_or_win_1.html A quick note about my java.net talk on generics at JavaOne.

Hand a new AffineTransform to ZomePane to show a new portion of the underlying view. It seemed simple to put together, but getting it to work was frustrating. Here's what finally worked.
