Computer scientist Cal Newport tells us how to practise "Digital Minimalism" - making technology work for you and not the other way around. Plus we chat to Michael Acton Smith, whose meditation app Calm has just become a "unicorn" - a company with a billion dollar valuation. And we discuss Instagram's vow to pull graphic images of self-harm from its platform after the father of a British teenager, who took her own life, said the site had "helped kill" his daughter.
