This is a very cool (new) extension that let you work with SSH inside your browser. It’s name is Secure Shell and it is an xterm-compatible terminal emulator and stand-alone ssh client for Chrome. It uses Native-Client to connect directly to ssh servers without the need for external proxies. I used it for few days and it’s working great. It’s useful on Chromebook (and ChromeOS) as a nice way to have access to a box that let you compile your C++/Java code. Also, as I’ve heard from few good people on stackoverflow, the need for Emcas (and/or) Vim on ChromeOS can be achieved via this nice extension.
