Sucks to be you, any aliens living anywhere near Proxima Centauri’s record-smashing solar flare • The Register

Astronomers have described the most energetic solar flare yet detected from Proxima Centauri, the Sun’s closest stellar neighbor.

It was a cosmic belch so intense, it’s now pretty clear the star cannot provide the right conditions to support familiar DNA-based life on its exoplanets.

On May 1, 2019, researchers led by the University of Colorado, Boulder, spotted a sudden burst of light erupting from Proxima Centauri unlike any other flare previously seen before.

“The star went from normal to 14,000 times brighter when seen in ultraviolet wavelengths over the span of a few seconds,” said Meredith MacGregor, lead author of a study into the solar outburst, just published in The Astrophysical Journal Letters, and an assistant astrophysics professor at the American university. A pre-print of the paper is here.

Using the data gathered from nine telescopes scattered across the Earth and in space, the team was able to calculate the power of the stellar explosion. “It’s about 1023 Watts,” MacGregor told The Register on Wednesday.

“A standard light bulb is 60 Watts, so that’s comparable to a whopping 1021 light bulbs.”

Red dwarf stars like Proxima Centauri emit flares more frequently than stable main-sequence stars like our Sun. A previous study reporting the discovery of a rocky exoplanet lying in Proxima Centauri’s habitable zone in 2016 ignited fresh hope and excitement that alien life could exist right under our noses in the closest stellar system, just 4.2 light years away.

But the latest observations of Proxima Centauri, captured using nine telescopes scattered around Earth and across space, show that life as we know it probably wouldn’t survive in such harsh conditions.

“Given the size of this flare and how frequently they occur, any life on the planet would have to look very different from what we see on Earth. UV radiation from flares like this could strip away the planet’s atmosphere, and damage the DNA of lifeforms on the surface,” MacGregor told us.

The record-breaking flare was a hundred times more powerful than ones ejected from our Sun, and lasted just seven seconds. Proxima Centauri’s two known planets are repeatedly bathed in the intense radiation from the star’s flares, making it difficult for them to sustain an atmosphere let alone alien life.

“A lot of the exoplanets that we’ve found so far are around these types of stars. But the catch is that they’re way more active than our sun. They flare much more frequently and intensely,” MacGregor said.

“If there was life on the planet nearest to Proxima Centauri, it would have to look very different than anything on Earth. A human being on this planet would have a bad time.” ®

South Korea sets reliability standards for Big Tech • The Register

Voice Of EU

Published

on

South Korea’s Ministry of Science and ICT has offered Big Tech some advice on how to make their services suitably resilient, and added an obligation to notify users – in Korean – when they fail.

The guidelines apply to Google, Meta (parent company of Facebook), Netflix, Naver, Kakao and Wavve. All have been told to improve their response to faults by beefing up preemptive error detection and verification systems, and create back up storage systems that enable quick content recovery.

The guidelines offer methods Big Tech can use to measure user loads, then plan accordingly to ensure their services remain available. Uptime requirements are not spelled out.

Big techs is already rather good at resilience. Google literally wrote the book on site reliability engineering.

The guidelines refer to legislation colloquially known as the “Netflix law” which requires major service outages be reported to the Ministry.

That law builds on another enacted in 2020 that made online content service providers responsible for the quality of their streaming services. It was put in place after a number of outages, including one where notifications of the problem were made on the offending company’s social media site – but only in English.

The new regulations follow South Korean telcos’ recent attempts to have platforms that guzzle their bandwidth pay for the privilege. Mobile carrier SK Broadband took legal action in October of this year, demanding Netflix pitch in some cash for the amount of bandwidth that streaming shows – such as Squid Game – consume.

In response, Netflix pointed at its own free content delivery network, Open Connect, which helps carriers to reduce traffic. Netflix then accused SK Broadband of trying to double up on profits by collecting fees from consumers and content providers at the same time.

For the record, Naver and Kakao pay carriers, while Apple TV+ and Disney+ have at the very least given lip service to the idea.

Korea isn’t the only place where telcos have noticed Big Tech taking up more than its fair share of bandwidth. The European Telecommunications Network Operators’ Association (ETNO) published a letter from ten telco CEOs asking that larger platforms “contribute fairly to network costs”. ®

Twitter acquires Slack competitor Quill to improve its messaging services

Voice Of EU

Published

As part of the acquisition, Quill will be shutting down at the end of the week as its team joins the social media company.

Twitter has acquired the messaging platform Quill, seen as a potential competitor to Slack, in order to improve its messaging tools and services.

Quill announced that it will be shutting down at the end of the week as its team joins the social media company to continue its original goal “to make online communication more thoughtful, and more effective, for everyone”.

The purchase of Quill could be linked to Twitter’s new strategy to reduce its reliance on ad revenue and attract paying subscribers.

Twitter’s general manager for core tech, Nick Caldwell, described Quill as a “fresher, more deliberate way to communicate. We’re bringing their experience and creativity to Twitter as we work to make messaging tools like DMs a more useful and expressive way people can have conversations on the service”.

Users of Quill have until 11 December to export their team message history before the servers are fully shut down at 1pm PST (9pm Irish time). The announcement has instructions for users who wish to import their chat history into Slack and states that all active teams will be issued full refunds.

The team thanked its users and said: “We can’t wait to show you what we’ll be working on next.”

Quill was launched in February with the goal to remove the overwhelming aspects of other messaging services and give users a more deliberate and focused form of online chat.

In an online post, Quill creator Ludwig Pettersson said: “We started Quill to increase the quality of human communication. Excited to keep doing just that, at Twitter.”

The company became a potential competitor for Slack, which was bought by Salesforce at the end of 2020 for $27.7bn. The goal of that acquisition was to combine Salesforce’s CRM platform with Slack’s communications tools to create a unified service tailored to digital-led teams around the world.

Last week, Salesforce announced the promotion of Bret Taylor to vice-chair and co-CEO, just days after he was appointed independent chair of Twitter after CEO Jack Dorsey stepped down.

Australians’ 2021 Google searches: Covid comes out on top with sport our favoured non-pandemic distraction | Google

Voice Of EU

The Covid-19 pandemic once again dominated internet searches in Australia this year, as lockdowns gripped the two largest states, and people sought vaccines.

Google has compiled data on the most popular search terms from the previous 12 months, which showed Covid’s dominance in Australia was challenged by people looking for an escape in sports. The NBA, AFL, cricket, NRL, football, Wimbledon and the Olympics took out the top spots for most searched sport in Australia in 2021.

The Covid situation in New South Wales dominated news-related searches, with the Delta outbreak forcing the state into the longest continuous lockdown in 2021. Victorians, having endured the most number of days in lockdown since the pandemic started, did not appear to seek out information about the Covid situation in their own state nearly as much, with “coronavirus Victoria” coming in fifth in news-related searches, even behind Queensland at number three.

For the second year in a row, people Googled “how to make face masks” more than any other DIY-related search. As residents in NSW, Victoria and the ACT endured extended lockdowns, at-home activities like making your own candles, playdough, paper planes, and chatterboxes soared.

As Australia’s vaccination “strollout” gathered pace in the second half of 2021, people searched how to get their vaccination certificates, how to book their Covid vaccination, how to link their Medicare to myGov, and how to enter the Million Dollar Vax campaign.

The shocking disappearance of West Australian four-year-old Cleo Smith and the dramatic rescue over two weeks later was the second biggest news event searched on Google by Australians. The ongoing search for missing toddler William Tyrrell came in sixth.

The former federal attorney general Christian Porter’s name dominated Google search trends in the days leading up to a press conference where he outed himself as the unnamed minister in an ABC report about an alleged historical rape. He vehemently denies the allegations. In his now-settled defamation suit against the ABC, lawyers for Porter raised that after the report searches of his name “increased significantly and much more so than any other senior male cabinet members”.

The former minister, who announced last week he would not recontest his WA seat of Pearce at the 2022 federal election, appears eighth in the 2021 list of news-related searches.

Porter was the fourth most-searched person overall in Australia, behind Cleo Smith, Ash Barty, and William Tyrell. The new NSW premier, Dominic Perrottet, came in sixth.

Bringing up the rear of news searches was the moment that shook Melbourne – literally – the 5.9 magnitude earthquake that hit Victoria in September.

Interest in all things cryptocurrency was also reflected in Australian searches with cryptocurrency exchange Coinspot the ninth most searched term, and people searched how to buy Dogecoin.

Prince Philip was the most searched among those who died in 2021, followed by US woman Gabby Petito, and Australian entertainment giant Bert Newton.

Thanks to Jaden Smith and Britney Spears, people were searching for the meaning of the word “emancipated” more than any other word in 2021, followed by “insurrection” after the events at the US Capitol on 6 January, then it was “gaslighting”, Naidoc and NFT.

Despite emerging late in the year, Omicron came in sixth as people looked up the meaning of the latest Covid-19 variant of concern.
