I like all three of the popular Java IDE’s and all three have plug-ins for Scala. I’ll probably try all three eventually, but since I’m totally [...]
When I first heard the idea that Java would be better off without null, I looked around for an explanation I could understand. Unfortunately, everything I found used code examples from languages without null. If I knew those languages, I wouldn’t be searching.
I wound up learning the “hard way” but now I figure I [...]

Why do we bother with multi-part numbers at all? Why not just use use a single revision number, like version 123? The parts of a version number communicate the magnitude of the change between the two versions. In the case of a library, this translates to how difficult the upgrade will be, which in [...]
It’s pretty easy to break binary and source compatibility simultaneously. Remove one parameter from a public method or delete a method entirely and no existing code that used the method will compile or run. But how can we break just binary or just source compatibility but not both?
… and why I can’t just let it go.
Whitespace is ignored by the compiler so it’s purely for readability. It’s there for you. Variable names have meaning and describe the intention of code. Similarly, whitespace describes the structure of a program.
These are files I used to configure my command line environment, plus the scripts used to generate these pages. I’m always looking to improve my setup so please send me any useful tips.
The Ant Timer is a plug-in that prints out diagnostic messages when ant targets and tasks take longer than the configured amount of time.
