Family on Boston bombings false IDs

Sangeeta Tripathi speaks to the BBC about the impact of false accusations about her missing brother and his role in the Boston marathon bombings.

Sunil Tripathi has been missing since March 16 after leaving home without his mobile phone and wallet.

Social news site Reddit’s Find Boston Bombers thread - known as a subreddit - named specific people standing near the scene as suspects.

They included innocent people such as 22-year-old Mr Tripathi and 17-year-old Salah Barhoun.

Reddit has issued a public apology for its coverage.

Ms Tripathi said her family were “weathered spirits” and spoke about how fast the unsubstantiated claims had spread.

Journalist Markham Nolan gives an excellent talk on how journalists tell fact from fiction in the digital world.

US film critic Roger Ebert given voice back by Edinburgh team

Short interview with Matthew Aylett, who lead the Edinburgh team that created a customised voice synthesiser for the late Roger Ebert.

Dr Aylett said the technology has moved on “dramatically” from the type of speech system developed in the 1980s and famously used by Professor Stephen Hawking.

He said: “Stephen Hawking is now identified by that voice, so he doesn’t want to change it. The difference here is the voice we’re giving Roger Ebert is actually the same voice he had before he had surgery.
