và thử lại.

Install Eclipse SDK on Fedora

Eclipse is an awesome IDE with tooling for various languages. It has a GTK+ UI that is much more accesible to regular programmers from a Windows environment than the tools traditionally used by FOSS hackers.
It was originally a (very) large body of code that IBM open-sourced. There is now a large community of companies and developers using and extending Eclipse.
It has its own Open Source license (the Eclipse Public Library, or EPL).
