Technology writer Charles Arthur discusses with Ivan six things which he thinks should be better known.

Charles Arthur's latest book, his third, is Social Warming, which looks at how and why social media has such a dramatically polarising effect on politics, journalism and societies around the world, even in countries where usage is low. His previous two books were on hacking (Cyber Wars, 2016) and the three-way tussle between Apple, Google and Microsoft in search, music and smartphones (Digital Wars, 2012). He was technology editor at The Guardian from 2005-2014, and before that had roles as the technology and science editor at The Independent from 1995-2013.

He writes The Overspill, a daily list of links and brief commentary about technology, science and whatever seems interesting (such as the wholesale moving of buildings from one place to another) at http://theoverspill.wordpress.com. The daily list is also available as an email. He is on Twitter at @charlesarthur, and The Overspill is @theoverspill. His work at The Guardian is at http://theguardian.com/profile/charlesarthur.
