This is a most excellent place for technology news and articles.
OpenSnitch is a nice for the desktop environment, deny by default and prompts the user when an application requests a open port, at first the prompts can get a little overwhelming given how many things want to connect to xyz server but eventually lightens up.

The firewall is annoying? I would argue and say the firewall is protecting your computer from connecting to a rouge server, annoying or not it’s better than some douche abusing an exploit in your system.
