Just run /simplify after you made your code changes and enjoy 🎉

#claudecode #ai #seniordeveloper #productivity

Claude Code 2.1.63 has a new awesome built-in command /simplify

It reviews your changed code over three dimensions: reuse (duplicated logic, extractable patterns), quality (readability, naming, structure), efficiency (unnecessary complexity, redundant ops). Then it automatically fixes those issues!

Wow! What a talk it was by Daniel Schwarz about multitude of ways to make your #Java apps faster. The #JUG Munich crowd asked a lot of tough questions which helped us to better understand the intricacies of #performance optimization. The recording will be available on JUGM YouTube channel soon.

In your Maven project simply run mvn wrapper:wrapper once and the Maven distribution and startup scripts will be downloaded to your project. Then instead of running "normal" commands like mvn compile run ./mvnw compile on MacOS/Linux or mvnw.cmd compile on Windows.

💡#Maven tip 👉 Make your builds more reliable by using Maven wrapper instead of a "plain" Maven. That way every developer working on your project will use the same Maven version and you'll eliminate one cause of non-repeatable builds. 👇
