It's not often you get to inspire an electric car speed record attempt, but it seems I've inadvertently done just that.

It began on Twitter, when I saw that there was an electric charging station in the parking lot at John O' Groats in Scotland, (almost) the most northern point of the Scottish mainland. The village is about as far from the most south-westerly point in the UK, Lands End in England, as it's possible to get without leaving the mainland: 874 miles (1.407km) to be precise. So, I idly wondered what the fastest journey time was for an electric vehicle. The idea then caught the eye of a TV presenter named Gareth Jones, host of the eponymous podcast Gareth Jones on Speed.

"Absolutely, it's all your fault," he told me when we spoke last week. "When you tweeted—I think it was March 7—a picture of the recharging point in John O' Groats, which has an Ecotricity charger, you said, 'I wonder what the record is from Lands End to John O' Groats?' I thought, that sounds like a plan. So I fairly casually, without much forethought, retweeted it, mentioning anyone who sells EVs in the UK asking if any of them wanted to give us a car."

My original tweet is unavailable, because I recently decided social media should be ephemeral like street art, and now anything older than a couple of weeks gets automatically deleted. But sure enough, Jones' declaration on March 7 is still there to behold:

So @JaguarUKPR @Hyundai_UK_PR @NissanUKPR @Tesla @KiaUK @RenaultUKPR

Any of you guys want to lend us a car and we will set a record for you, and make an episode of Gareth Jones On Speed about it.#OnSpeedLandsEndToJohnOGroatsEVRecord

Hyundai was the first to respond to Jones, offering the use of a Kona EV. Jones roped in Paul Ireson (aka Zog), his friend and co-presenter on the podcast. "I got in touch with Zog—he's about the only really bright mind on the show—to look at the maths of it and see whether it could actually be done, and he thought it could," Jones said. "Using a 50kW recharging network, with a car with a 64kWh capacity, most of the journey is at 70mph (113km/h). He calculated that we could break the record."

Soon armed with a car and a route, the two set off for Cornwall to start the record attempt on May 17. Jones said they didn't make even the smallest modifications, like taking out the back seat ("We didn't even pump up the tires beyond the recommended pressures," as he put it). And from the sounds of it, there weren't really any real modifications to their driving style either.

"We werent driving to maximize range. I did some back of the envelope calculations—do we want to do 50mph (80km/h) strategy and eek out maximum range, or do regular motorway speed and get to the next stop quicker?" Ireson told Ars. "It was clear that normal motorway speed gives you a better overall average speed. If you assume youre 25% less efficient at 70mph, therefore getting worse range, going a slightly shorter distance faster, then recharging, you should have an average speed of about 52mph (84km/h); it's about 41mph (66km/h) if you hypermile."

The best-laid plans

Unfortunately, the record attempt was in trouble from the start—the duo found out the Ecotricity charger at Lands End was out of order, meaning they couldn't start the journey with a 100% charge. Their original plan was to arrive in Lands End in the early afternoon to recharge the car and grab a few hours' sleep before setting off after dark. "Unfortunately, we lost hours and hours and hours recharging on the way down and so arrived at 8:45pm, went into the hotel, said, 'Can you sign this?' [a reference to a time card], and then we left," Jones said. "We started on the back foot because the car wasn't fully charged."

The existing record for an electric car journey between those two points stood at 19 hours and 45 minutes, a mark set by Jeff and Ben Allan in an 85kWh Tesla Model S back in 2015. In fact, Jones says there is no official Guinness record category for the journey. "They recognize the shortest recharging time, which stands at 3 hours 44 minutes and 33 seconds," he said. "Obviously, [the Allans] used Tesla's 120kW supercharger network for the bulk of that journey. But I believe when they did there were no superchargers in Scotland."

Sadly for our intrepid pair, the Kona EV can only charge at up to 75kW, a good deal slower than the Tesla. Worse yet, the DC fast chargers on their route weren't even that powerful. "The fastest chargers were up to, and here&#039Read More – Source

Twitter users are exposing pro-Russian sentiment in China, and Beijing is not happy



Anonymous Twitter users are exposing the extreme nationalism and pro-Russian sentiment circulating online in China — and Beijing is not happy about it.

Scores of screen-grabbed posts from China’s most popular social media platforms have been translated and shared on Twitter in recent weeks, offering Western audiences a rare glimpse into the Chinese internet.
Among those posts: a prominent military blog falsely claiming a Russian attack on a train station in Kramatorsk was actually carried out by Ukraine, a well known media commentator dismissing the atrocities in Bucha, and a vlogger with hundreds of thousands of followers using a misogynistic term for Ukraine.
The posts appear courtesy of anonymous Twitter users who say their aim is to expose Western audiences to the true extent of pro-Russian or nationalistic content on China’s heavily censored platforms.
They often come under the hashtag of “The Great Translation Movement,” or shared by an account with the same name run by a decentralized, anonymous team that crowdsources the collection and translation of popular posts on Ukraine and other hot topics, according to an administrator interviewed by CNN. Many, but not all, appear to have been widely liked or shared within China — selection criteria cited by the administrator.
Since the account’s launch in early March it has already made plenty of friends and enemies — attracting both 116,000 followers (and counting) and a slew of criticism from China’s state-run media.
The movement was formed in response to China’s alleged hypocrisy in portraying itself as neutral on Ukraine, even while its state and social media circulated pro-Russian narratives, the administrator told CNN.
“We want the outside world to at least know what is going on inside, because we don’t think there could be any change made from inside,” said the administrator, who requested anonymity due to security concerns.

In bad faith?

China’s state media has lashed out against what it decries as “cherry picked content.” The overseas arm of the People’s Daily — the mouthpiece of China’s ruling Communist Party — has claimed the translators behind the movement are guilty of attributing the “extreme remarks” of some netizens to the “whole country.”
The nationalistic Global Times newspaper has accused the group of being “Chinese-speaking bad faith actors” and one of its opinion writers claimed the group included “foreign hostile forces” perpetuating “psychological warfare against China.”
Outside China, media experts caution the posts do not show a holistic view of public opinion in China and appear to at least partially be selected for shock value — but could still be useful in bringing these elements of China’s media sphere to light.
Critics also say the group’s tweets show evidence of its own bias — such as in posts that use a term comparing China to Nazi Germany.
Posts which gain traction on China’s social media must be seen in light of its highly censored environment, where nationalistic voices thrive and liberal ones have largely retreated or been censored, experts say.
But the administrator who spoke to CNN said the point was to highlight the visibility of such posts — some coming from popular influencers, comments receiving thousands of likes or from prominent commenstators, and even government-backed news outlets.
“Our goal is to raise awareness about the state of public opinion in China, whether it is purely the result of spontaneous interactions (or) the result of government censorship,” the administrator said.
“We want to counter the effort of the Chinese state-affiliated media by showing the West some content they do not want to show.”

Dual messaging

The resistance against the group from China’s state media highlights the sensitivities around how China wants to present itself on the world stage, especially at a time when it has been attempting to walk a diplomatic tightrope between Russia and the West over Ukraine.
China has often sought to present two different narratives — one for domestic audiences and another for those overseas. This is made possible through both a language barrier and an online ecosystem that bans apps like Facebook, Twitter and Instagram. The Great Translation Movement breaks down both of these barriers.
“Even before the social media era, the way China talks internally through its state media is something it doesn’t appreciate being parsed and translated for the world,” said David Bandurski, director of the China Media Project, a research program in partnership with the Journalism & Media Studies Center at the University of Hong Kong.
And when it comes to Ukraine, China has sought to portray itself — at least to overseas audiences — as unaligned and invested in calling for peace. But its media coverage back home tells a different story, Bandurski said.
“If you just look at (state) media coverage, it’s really hard to talk about neutrality … Everything they have said is amplifying disinformation and aligning with Russia in terms of narratives.”
While the tone of state-backed media is clear, experts say it is difficult to gauge public opinion in China simply by looking at social media, even when it comes to popular influencers or viral posts.
Like anywhere in the world, views on social media can be extreme. In China, heavy manipulation and censorship often amplifies select voices.
“The authorities certainly have an interest in promoting their preferred narrative online, and they have the technical and political means to unapologetically ‘guide public opinion,'” said Florian Schneider, director of the Leiden Asia Center in The Netherlands.
“We should also not underestimate the power of social media algorithms: as pro-Russia statements become mainstream, they receive ever more likes and shares, which makes them more visible,” he said.

Suppressed voices, echo chambers

The situation is complicated: Beijing too has reason to be wary of ultra-nationalist voices, which platforms sometimes censor. And while nationalist rhetoric has become more dominant online in recent years, the loudest voices may not show a majority.
Bandurski said that an analogy would be looking at ultra-conservative voices in the US media environment, and assuming that was representative of the American perspective.
“So the danger is this kind of echo chamber of content, which we might assume is representative of China and its perspective, and it’s really a lot more complicated than that,” he said.
Maria Repnikova, director of the Center for Global Information Studies at Georgia State University, said when it comes to Ukraine there have been “alternative voices talking about the war…but they’re not as dominant or as loud or as visible.” Their posts may either be censored or hard to detect as social media users may express dissenting views through code and allusion.
She also asks if things would be different if images of bombarded cities of Ukraine or the atrocities in Bucha were not restricted in China.
“If people could see all of those images and scenes, would that be a different story? Would different voices pick up?”
The Great Translation Movement administrator said they hoped that the movement could help push Beijing to tone down the rhetoric on these platforms so that there would be room for more voices.
“In today’s Chinese mainstream discourse there is a very limited space for people who have a rational mind to speak,” the administrator said.
“Even if you speak out and if it doesn’t get deleted, you are still going to be spammed…and people are going to say you are a spy… the dignity of people themselves is destroyed.”

independent– BlackBerry phones, once the height of mobile devices, are finally being shut off.

The company announced that services for the older devices will be brought to an end on 4 January. At that point, they will “no longer reliably function”, BlackBerry said, and will be unable to get data, texts or make phone calls, including to emergency numbers.

It is just the latest in a series of endings for the once equally beloved and hated name, which helped drive the mobile revolution and was at the forefront of business and technology. While the BlackBerry has been declared dead a number of times before, the latest move means that the phones themselves will actually stop working.

In 2016, after its phones had been replaced largely by smartphones from Apple and others, BlackBerry announced that it had transitioned away from phones and into making software and that it would focus on providing security tools to companies and governments. It has sold the BlackBerry brand to other companies, who have created devices bearing the name.

In 2020, BlackBerry said that with that move complete, it would start taking offline the legacy services that allowed those old devices to keep working. Phones that run any of BlackBerry’s own operating systems – BlackBerry 7.1 OS and earlier, BlackBerry 10 software – were given an “end of life or termination date” at the start of 2022.

Next week, that date will finally arrive and support will end. While the phones will still be able to perform some of their functions without BlackBerry’s services, many of their central features will be removed, and the phones will not work reliably.

BlackBerry said the support was being removed in recognition of the fact that it now works in security software and that the old products did not reflect its business. It had prolonged support in the years since that transition “as an expression of thanks to our loyal partners and customers”, it said.

70 Jupiter-sized ‘rogue planets’ discovered in our galaxy



independent– A team of astronomers discovered at least 70 ‘rogue’ planets in our galaxy, the largest collection ever found to date.

While conventional planets (like those in our Solar System) orbit a star, rogue planets roam freely without travelling around a nearby star.

“We did not know how many to expect and are excited to have found so many,” said Núria Miret-Roig, an astronomer at the Laboratoire d’Astrophysique de Bordeaux.

­It would usually be impossible to detect rogue planets because they are hard to spot far from a star’s light. One key fact of their existence made them visible: these planets still give off enough heat to glow millions of years after their creation, making them visible to powerful telescopes.

This heat allowed the 70 planets – each with masses close to that of Jupiter – to be discovered in the Scorpius and Ophiuchus constellations.

“We measured the tiny motions, the colours and luminosities of tens of millions of sources in a large area of the sky,” explained Ms Miret-Roig. “These measurements allowed us to securely identify the faintest objects in this region, the rogue planets.”

The astronomers’ study suggests there could be many more elusive, starless planets yet to be discovered, numbering in the billions in the Milky Way alone.

By studying these planets, astronomers believe they could unlock clues as to how the mysterious objects come to be. It is hypothesised they are generated from the collapse of gas clouds too small to create stars, but they could also have been ejected from a parent system.

“These objects are extremely faint and little can be done to study them with current facilities,” says Hervé Bouy, another astronomer at the Laboratoire d’Astrophysique. “The ELT [Extremely Large Telescope, currently being built in Chile] will be absolutely crucial to gathering more information about most of the rogue planets we have found.”

The exact number of rogue planets discovered is vague, because the observations made by the researchers do not allow them to measure the mass of the objects. Bodies with a mass 13 times greater than that of Jupiter are unlikely to be planets, but relying on brightness makes this figure unclear.

The brightness of these objects is also related to age, as the older the planet is the dimmer it will be. The brightest objects in the sample could have a mass greater than the upper limit but be older and therefore dimmer. Researchers estimate there could be as many as 100 more planets yet to be discovered because of this uncertainty.
