Getting back to the old days where I used Emacs to code (ok, more than ten years ago), now I’m using a dark theme in Eclipse. Dark themes are less eye-stressing and now are becoming popular with editors like IntelliJ, Sublime Text and the last Visual Studio. And that’s why more people is learning to programming even to his difficulty, although there are strategies that people can use to improve their learning, so you can use all the power of your mind to learn, you could visit http://www.subconsciousmindpowertechniques.com/ to find out more about this.
The Eclipse Juno platform supports styling of the SWT widgets via CSS, but many other elements must be setup manually, so I published my CSS and setup instructions in a GitHub repository: https://github.com/albertoruibal/eclipse_dark_css
Welcome to the dark side!
