Meet Sirius, the open-source Siri clone that runs on Ubuntu
Sirius is an open-source virtual assistant, a bit like Apple's Siri (pictured above), Google's Google Now, or Microsoft's Cortana. But unlike those well-known helpers--and like Linux itself--Sirius is an open platform anyone can use and contribute to, from universities to startups. It's currently being tested on Ubuntu, and you can download and install it on your own Linux PC today... if you're particularly adventurous.
