‘It’s an arms race’: the tech teams trying to outpace paedophiles online

As platforms pivot towards greater encryption, analysts are rushing to finesse child abuse prevention technology

“Predators are often early adopters of technology,” says Sarah Smith, chief technology officer at the Internet Watch Foundation (IWF), a UK child abuse hotline. “It’s an arms race, we have to be constantly horizon-scanning.”

Smith and her team, based in an unassuming office in Cambridge, are a key link in a chain of experts around the world developing and finessing technology that tracks down paedophiles and removes child abuse images found online.

Service from MyHeritage uses deep learning technique to automatically animate faces

Deep Nostalgia, a new service from the genealogy site MyHeritage that animates old family photos, has gone viral on social media, in another example of how AI-based image manipulation is becoming increasingly mainstream.

Launched in late February, the service uses an AI technique called deep learning to automatically animate faces in photos uploaded to the system. Because of its ease of use, and free trial, it soon took off on Twitter, where users uploading animated versions of old family photos, celebrity pictures, and even drawings and illustrations.

Lenovo ThinkPad X1 Fold review: a glimpse at the future of folding PCs

Tablet PC screen that folds like book or as dual-screen laptop is incredible piece of technology but not ready for mass market

Lenovo’s ThinkPad X1 Fold is an entirely new form – a tablet PC that closes like a book with a foldable screen. It may just be the future of the computer.

The £2,500-plus X1 Fold joins a rarefied group of cutting edge folding-screen devices that include the reinvention of the flip phone and a mobile tablet that folds in half to fit in your pocket.

Fossil fuel cars make ‘hundreds of times’ more waste than electric cars

Analysis by transport group says battery electric vehicles are superior to their petrol and diesel counterparts

Fossil fuel cars waste hundreds of times more raw material than their battery electric equivalents, according to a study that adds to evidence that the move away from petrol and diesel cars will bring large net environmental benefits.

Only about 30kg of raw material will be lost over the lifecycle of a lithium ion battery used in electric cars once recycling is taken into account, compared with 17,000 litres of oil, according to analysis by Transport & Environment (T&E) seen by the Guardian. A calculation of the resources used to make cars relative to their weight shows it is at least 300 times greater for oil-fuelled cars.

Department of Justice said to have asked WhatsApp for details of alleged targeting of clients in 2019

‘Record companies have me on a dartboard’: the man making millions buying classic hits

Hit songs can be a better investment than gold – and by snapping up the rights, Merck Mercuriadis has become the most disruptive force in music

Merck Mercuriadis had a good Christmas. On Christmas Day, the No 1 song in the UK was LadBaby’s Don’t Stop Me Eatin’, a novelty cover version of Journey’s 1981 soft-rock anthem Don’t Stop Believin’. It replaced Mariah Carey’s All I Want For Christmas Is You, which had topped the chart 26 years after its original release. Both songs are unkillable, evergreen hits, which are closing in on 1 billion Spotify streams apiece. Both songs are among the 61,000 owned, in whole or in part, by Mercuriadis’s investment company, Hipgnosis Songs Fund, and epitomise the thesis that has made the 57-year-old Canadian, in less than three years, the most disruptive force in the music business.

Put simply, Hipgnosis raises money from investors and spends it on acquiring the intellectual property rights to popular songs by people like Mark Ronson, Timbaland, Barry Manilow and Blondie. In a fast-growing market, what sets Hipgnosis apart from competitors is its founder’s bona fides as a veteran A&R man, manager and record label CEO. Like an old-school music mogul, Mercuriadis sells his brand by selling himself. Unlike those moguls, he’s a buff, teetotal vegan with spartan tastes. “The only material thing that I really care about is vinyl,” he says. “And Arsenal football club.” He looks rather like a rock-concert security guard: shaven head, burly torso, plain black T-shirt, hawkish gaze. Mark Ronson calls him “the smartest guy in the room”.

Electricity needed to mine bitcoin is more than used by ‘entire countries’

Bitcoin mining – the process in which a bitcoin is awarded to a computer that solves a complex series of algorithm – is a deeply energy intensive process

It’s not just the value of bitcoin that has soared in the last year – so has the huge amount of energy it consumes.

The cryptocurrency’s value has dipped recently after passing a high of $50,000 but the energy used to create it has continued to soar during its epic rise, climbing to the equivalent to the annual carbon footprint of Argentina, according to Cambridge Bitcoin Electricity Consumption Index, a tool from researchers at Cambridge University that measures the currency’s energy use.

WhatsApp to try again to change privacy policy in mid-May

Firm sets 15 May deadline to agree to new terms but will let notifications continue for short time afterwards

After an abortive attempt to change its privacy policy led to millions of users signing up for competing services, WhatsApp has said it will try for a second time to roll out the update in mid-May.

In an effort to smooth the transition, WhatsApp will for the first time allow limited access to its services for users who do not agree to the new terms of service. From 15 May, those users will no longer be able to send or read messages but will continue to be able to receive calls and notifications for a “short time”.

Eliot Higgins: ‘People accuse me of working for the CIA’

The founder of the online investigative collective Bellingcat talks about working with Alexei Navalny, open source reporting and the trouble with ‘cyber-miserablism’

Eliot Higgins launched Bellingcat in summer 2014, days after the Russian military shot down Malaysian Airlines MH17 over eastern Ukraine. The online outfit has broken a series of international scoops. In 2018 it discovered the identities of the two undercover assassins who poisoned Sergei Skripal in Salisbury. Last year Bellingcat revealed extraordinary details of the plot by Russia’s FSB spy agency to poison the opposition leader Alexei Navalny.

Higgins’s first book tells the story of how open source investigation has redefined reporting in the 21st century. He argues that the internet can still be a force for good, despite bad actors, complacent technology firms and an explosion in alternative “facts”. Higgins lives in Leicester with his wife, daughter and son.

Artificial constraint highlights struggle to keep up with demand from cryptocurrency miners

The newest graphics cards from the gaming processor designer Nvidia will be artificially constrained in their ability to mine cryptocurrencies, the company has announced, as it desperately tries to manage a year-long inability to satisfy demand.

From a treadmill and a puppy to 19th-century curtains, here are the purchases that have helped cheer people up in the past year

Sacha Baron Cohen: ‘If you’re protesting against racism, you’re going to upset some racists’

Stopping Trump, reforming Facebook and risking his life to make a Borat sequel. In an exclusive interview, the actor unveils his plans for a revolution – and reveals how it feels to come out as himself

Seven months ago, Sacha Baron Cohen was in the back of a speeding ambulance. It was an escape car, and he was fleeing a gun rally. The Borat producers had chosen the ambulance as it could blend in, accommodate a small film crew and, if necessary, hasten a trip to hospital.

Baron Cohen – dressed as Borat, himself disguised as a country singer – had just led the crowd of far-right conspiracy theorists in a singalong. At first, they happily joined in: “Obama, what we gonna do? / Inject him with the Wuhan flu.” Then one or two smelled a rat. Then they all stormed the stage.

Facebook is ‘schoolyard bully’ in Australia news row, says UK media boss

Trade group chairman says robust regulation is needed to rein in monopolistic tech firms

Facebook’s move to block all media content in Australia shows why countries need robust regulation to stop tech firms behaving like a “schoolyard bully”, the head of the UK’s news media trade group has said.

Henry Faure Walker, the chair of the News Media Association, said Facebook’s ban during a pandemic was “a classic example of a monopoly power being the schoolyard bully, trying to protect its dominant position with scant regard for the citizens and customers it supposedly serves”.
