New Ideas for Old Code

Left unattended software can expand into a complex, brittle maintenance nightmare. Don't despair! This session teaches strategies for modernizing even the most horrid code swamps, examining incremental refactorings and the dos and don'ts of testing legacy code. We'll also tackle the harder, cultural issues: how to inspire your co-workers and keep your moral high even on the dirtiest jobs.

Code Generation on the JVM

"The Pragmatic Programmer" admonished us all to "write code that writes code": use code generators to increase productivity and avoid duplication. Today's language communities have clearly caught on, as more and more frameworks generate code at compile time: AST Transforms, Project Lombok, Spring Roo, and more. This session reviews these approaches including examples of how and why we'd want to do this. Come see the newest Groovy language tools, look in-depth at production deployed AST Transforms, and view libraries based on these techniques. Audience: developers searching for cutting edge solutions to increasing team velocity.
