ProGuard is a free Java class file shrinker, optimizer, obfuscator, and preverifier. It detects and removes unused classes, fields, methods, and attributes. It optimizes bytecode and removes unused instructions. It renames the remaining classes, fields, and methods using short meaningless names. Finally, it preverifies the processed code for Java 6 or for Java Micro Edition.

The “Java Decompiler project” aims to develop tools in order to decompile and analyze Java 5 “byte code” and the later versions.

The solution that worked for me was to copy these files:

But Hertzfeld said the most formative lesson he learned from Wozniak and Jobs, who he remained close to until Jobs' death last fall, was to bring emotion and art to computer design.

"First and foremost, you are your own customer: You build stuff that you love yourself. What Woz did with the Apple II was he just filled it up with so much love -- love because it was his lifelong dream," Hertzfeld said.
