Readers of my blog know about Elvis, the Microsoft
persona of the programmer who is neither Einstein nor the
point-and-click/drag-and-drop "just give me a wizard" Mort. Elvis wants to
use EJB 3 because the annotations make it easy, but he is a bit taken
aback by the jargon.
I am working on a glossary that gives both the official definition of
various terms (starting with...
It's summer again, people have more time on their hand, and they think
about switching operating systems:
From Windows
to Mac OS X

Ubuntu 6.06 "Dapper Drake" system. The build
instructions warn you not to try this at home. The official build

line:
java -javaagent:toplink-essentials-agent.jar client.Client
What is the reason behind that? Go to the GlassFish
forum and search for javaagent. You'll get lots of confused queries.
(Ok, most of them are mine.) The gist of the...

tutorial.

private int quantity;
private String product;

Several years ago, I switched from Emacs to Eclipse. It was a bit
painful at first, but Eclipse had two killer features that, once I
discovered them, I could not live without.
