Lessons Learned in January 2017

This is what I learned in January 2017:

At one of our HackTalk meetings, I learned about how to use the Java WebStarter. Here is a protocol (in German).
This month, Axosoft released a 2.0 version of their Git client, GitKraken. It’s much faster than previous versions and is really fun to use. If you haven’t tried it out yet, go ahead!
Last week, I removed all files created by IntelliJ IDEA from our Git repository. They got in there in a weak moment when we decided to “just check it in, we can care later about it”. Those files changed every time Maven dependencies changed. If checked in, they polluted the history. Because the .idea folder has been checked in, just adding it to .gitignore didn’t change anything. The files had to be deleted to get ignored by Git using a proper .gitignore. Now, everything is fine because only the project files are in source control.
