Software called etcd, used for storing data across clusters of containers, has a problem – it does not implement authentication by default and so poses a security risk if deployed without further fiddling.

Troy Mursch, a security researcher with Bad Packets Report, said in an email to The Register, said, "I've independently verified [this issue] and confirmed it's a serious concern for anyone running etcd open to the internet."

Thanks to a new upgrade process, the next update—expected to be released in April—should result in substantially less downtime. The install process is split into two portions: the "online" portion, during which your PC is still usable, and the "offline" portion after the reboot, during which your PC is a spinning percentage counter.

Microsoft estimates that the Creators Update, released almost a year ago, would take about 82 minutes on average during the offline phase. Improvements made in the Fall Creators Update cut that to about 51 minutes, and the next update (which still hasn't actually been blessed with an official name) will cut this further still, to just 30 minutes.

The 100TB ExaDrive has a 3.5-inch enclosure, a SATA interface, and is built from MLC (2bits/cell) 3D NAND. It has, Nimbus claims, the lowest power/TB rating, down to 0.1W/TB, 85 per cent lower than Micron's 5100 drive.

Savings offered by the ExaDrive over these drives are physical space and power. A theoretical 100PB constructed from 3,264 Samsung PM1643 SSDs would need 6 x 45U racks, according to Nimbus, and around 50kW of power.

The same ExaDrive-sourced capacity would need one rack, 990 drives and draw about 16kW.

“It’s horrifying how much they know,” he told the Guardian, on the condition of anonymity. “You go into Facebook and it has this warm, fuzzy feeling of ‘we’re changing the world’ and ‘we care about things’. But you get on their bad side and all of a sudden you are face to face with [Facebook CEO] Mark Zuckerberg’s secret police.”

It’s a similar story at Google. Staff use an internal version of Google Plus and thousands of mailing lists to discuss everything from homeownership to items for sale, as well as social issues like neoconservatism and diversity.

One European Facebook content moderator signed a contract, seen by the Guardian, which granted the company the right to monitor and record his social media activities, including his personal Facebook account, as well as emails, phone calls and internet use. He also agreed to random personal searches of his belongings including bags, briefcases and car while on company premises.

The data analytics firm that worked with Donald Trump’s election team and the winning Brexit campaign harvested millions of Facebook profiles of US voters, in one of the tech giant’s biggest ever data breaches, and used them to build a powerful software program to predict and influence choices at the ballot box.

The discovery of the unprecedented data harvesting, and the use to which it was put, raises urgent new questions about Facebook’s role in targeting voters in the US presidential election.

Industry insiders fear that, without agreement, the Whois service, which publicly lists full contact details of domain-name registrants, will effectively shut down in order to avoid fines and possible lawsuits under the Euro rules.

That would leave law enforcement and intellectual property lawyers, among others, unable to access registrant details, and potentially give cybercriminals a larger window to carry out crimes.

Russia has been condemned at the UN security council for the Salisbury nerve agent attack, with allies lining up to back Britain’s assessment that Moscow bears responsibility.

Nikki Haley, striking a contrast to her strangely equivocal president, told the UN security council: “The United States believes that Russia is responsible for the attack on two people in the United Kingdom using a military-grade nerve agent … The credibility of this council will not survive if we fail to hold Russia accountable.”

The British scientist was famed for his work with black holes and relativity, and wrote several popular science books including A Brief History of Time.

They praised his "courage and persistence" and said his "brilliance and humour" inspired people across the world.

Japanese scientists have found that even the slightest slither of light when trying to sleep could be linked to a heightened risk of depression, according to a new study published in The American Journal of Epidemiology.

The modern world is beaming with almost constant exposure to artificial light. Light at night (LAN) in a bedroom – even a flash of a digital clock or streetlight creeping in from a crack in the curtains – could screw with our natural sleep/wake cycle.

Starting with the April 17 release of Google's Chrome 66 browser, all SSL/TLS certificates that Symantec issued prior to June 1, 2016, will be flagged by Chrome as unsafe, as well as those issued by Symantec-owned brands such as Verisign, Thawte and Equifax.

Starting with Chrome 70, all websites with SSL/TLS certificates that Symantec issued after June 1, 2016, will be impacted in the same way. Google will release the First Canary of Chrome 70 on July 20.
