Guys, you probably won't believe me but the most useful software I've ever discovered is a mirror for torrents. In case you don't know what is a "mirror" - A mirror site is a website or set of files on a computer server that has been copied to another computer server so that the site or files are available from more than one place. A mirror site has its own URL, but is otherwise identical to the principal site." I think this way you'll understand what's that. Through mirror for torrents like
The Pirate Bay you can download any content you wish.
So, yeah, that's my discovery.)
