Well they ain't java developers,
Cause java compiles in seconds.*

*Lousy slow C++. It executes as fast as it compiles. Have my word on that one. Jeśli zauważasz że Java jest wolniejsza od C++, to pewnie używasz Javy 1.4, albo (nie daj Boże) gcj. Java 1.5 jest skokiem jakościowym jak między C a C++.

Long time ago I was working in a project that had half of its codebase in C++, and half in Java. Java developers started their day starting their Java IDE, and while it was starting, they were making themselves coffe. C++ programmers started Emacs, and went working straight on. No coffe for C++ programmers!
