Hot-deploy your code – keep focus on your work
Time is money. Something that I still don’t get is that many Java developers spend a lot of it (time and money) while waiting to see their latest code changes in action. JVM is known for its great peak performance when serving large numbers of users, but our tooling isn’t by default that well ...
