Yesterday, I saw my friend using “tabedit” in vi. Being an emacs user, I strongly feel that this feature will be a definitive productive boom. I started to google and stumbled on a stackoverflow question. The answer by @Abdel introduced me to EIScreen.

We will also write our first HelloWorld service. Continue reading →
