So I used cloud9. The advantages are - they spin boxes for you.Imagine you want to try that new tech without installing virtual box or vagrant on your computer,well that's how I started learning go.Integrated multi-user programming. - You can do peer programming easily or if you are doing some tutoring you can see what the student is typing and correct it.So 2 people can work on the same files at the same time,... - cloud9 editor has good performances,integrates well with git,github and co. - You can preview web projects online directly(start a server,go to a url and see the result...), - SSH login into you own box or server and remote file editing with. Now does it have "intellisense" or autocompletion or refactoring tools for Java,C# and Co? no. But it does a good job at editing scripting language files. The appeal here is really, quick editing or quick experiments.It's a bit like js fiddle,it's a code playground. And it's opensource(at least the previous version was).
