HBO Max has been mocked and consoled after sending out an unusual email to its customers. The message – apparently sent to a significant numbers of the service's subscribers – was not advertising a new show or feature, but rather included only a cryptic message that appeared to have been sent out by mistake. "This template is used by integration tests only." As recipients opened the email, and quickly realised that it had been sent by mistake, the reaction ranged from mockery to sympathy for the person who had clearly sent what was an internal test email out to potentially millions of subscribers.

Plans to allow CCTV cameras to recognise people's faces in realtime could be used "inappropriately, excessively or even recklessly", the Information Commissioner has warned. In recent years, authorities have been rolling out new kinds of facial recognition, with the promise that it would be able to spot dangerous people in real-time. But privacy activists and others have warned that it is a vast invasion of privacy, could be used to create watchlists of people, might falsely accuse people because of racism and other biases and unfair practices. There is still time for authorities to change their mind and avoid the vast dangers that the technology could produce, the head of the watchdog warned. "We're at a crossroads right now, we in the UK and other countries around the world see the deployment of live facial recognition and I think it's still at an early enough stage that it's not too late to put the genie back in the bottle," Commissioner Elizabeth Denham told the PA news agency.
