Will Neural Sensors Lead to Workplace Brain Scanning?

“Get ready: Neurotechnology is coming to the workplace,” claims IEEE Spectrum:

Neural sensors are now reliable and affordable enough to support commercial pilot projects that extract productivity-enhancing data from workers’ brains.

These projects aren’t confined to specialized workplaces; they’re also happening in offices, factories, farms, and airports. The companies and people behind these neurotech devices are certain that they will improve our lives. But there are serious questions about whether work should be organized around certain functions of the brain, rather than the person as a whole.

To be clear, the kind of neurotech that’s currently available is nowhere close to reading minds. Sensors detect electrical activity across different areas of the brain, and the patterns in that activity can be broadly correlated with different feelings or physiological responses, such as stress, focus, or a reaction to external stimuli. These data can be exploited to make workers more efficient — and, proponents of the technology say, to make them happier. Two of the most interesting innovators in this field are the Israel-based startup InnerEye, which aims to give workers superhuman abilities, and Emotiv, a Silicon Valley neurotech company that’s bringing a brain-tracking wearable to office workers, including those working remotely….
EEG has recently broken out of clinics and labs and has entered the consumer marketplace. This move has been driven by a new class of “dry” electrodes that can operate without conductive gel, a substantial reduction in the number of electrodes necessary to collect useful data, and advances in artificial intelligence that make it far easier to interpret the data. Some EEG headsets are even available directly to consumers for a few hundred dollars.

Facebook's Fact-checkers Will Stop Checking Trump After Announcement of Presidential Bid

CNN reports:

Facebook’s fact-checkers will need to stop fact-checking former President Donald Trump following the announcement that he is running for president, according to a company memo obtained by CNN.

While Trump is currently banned from Facebook, the fact-check ban applies to anything Trump says, and false statements made by Trump can be posted to the platform by others. Despite Trump’s ban, “Team Trump,” a page run by Trump’s political group, is still active and has 2.3 million followers…. The carve-out is not exclusive to Trump and applies to all politicians, but given the rate fact-checkers find themselves dealing with claims made by the former president, a manager on Meta’s “news integrity partnership” team emailed fact-checkers on Tuesday ahead of Trump’s announcement. …

The company has long had an exception to its fact-checking policy for politicians. “It is not our role to intervene when politicians speak,” Meta executive Nick Clegg, a former politician, said in 2019, defending the exemption. The Meta memo sent to fact-checkers made clear that if Trump announced a 2024 presidential bid Tuesday night, he could no longer be fact-checked on the platform. The memo noted that “political speech is ineligible for fact-checking. This includes the words a politician says as well as photo, video, or other content that is clearly labeled as created by the politician or their campaign.”
It concluded that “if former President Trump makes a clear, public announcement that he is running for office, he would be considered a politician under our program policies.”

Andy Stone, a Meta spokesperson, said the memo was “a reiteration of our long-standing policy” and “should not be news to anyone….”

Meta plans on considering allowing Trump back on the platform as soon as January — two years since his initial ban.

Chinese Takeover of UK's Largest Chip Plant Blocked on National Security Grounds

Slashdot has been covering plans for the UK’s largest chip plant to be acquired by Chinese-owned firm Nexperia.

But this week the U.K. government “has blocked the takeover of the country’s largest microchip factory by a Chinese-owned firm,” CNBC reported this week, “over concerns it may undermine national security.”

Grant Shapps, minister for business, energy and industrial strategy, on Wednesday ordered Dutch chipmaker Nexperia to sell its majority stake in Newport Wafer Fab, the Welsh semiconductor firm it acquired for £63 million ($75 million).

Nexperia is based in the Netherlands but owned by Wingtech, a partially Chinese state-backed company listed in Shanghai. Nexperia completed its acquisition of Newport Wafer Fab in 2021, and the firm subsequently changed its name to Nexperia Newport Limited, or NN.

“The order has the effect of requiring Nexperia BV to sell at least 86% of NNL within a specified period and by following a specified process,” the United Kingdom’s Department for Business, Energy and Industrial Strategy said in a statement. Nexperia had initially owned 14% of Newport Wafer Fab, but in July 2021 it upped its stake to 100%.

“We welcome foreign trade & investment that supports growth and jobs,” Shapps tweeted Wednesday. “But where we identify a risk to national security we will act decisively.”

Nexperia plans to appeal the decision.

Elon Musk says he will unban Donald Trump after Twitter poll

A few weeks after he took over Twitter, Elon Musk said he will fulfill one of his early promises for the platform, reinstating Donald Trump’s account. The former president, who is running for the White House for a third time, will once again be allowed to tweet, Musk said. 

Twitter’s new CEO appeared to make the decision via a Twitter poll. On Friday night, Musk tweeted a poll asking people to vote on whether Twitter should reinstate the former President, who recently just revealed that he will run for the country’s highest office again in 2024. “Vox Populi, Vox Dei,” Musk said in a follow-up tweet. The phrase is Latin for “the voice of the people, the voice of God.” Twenty-four hours later, the poll had closed, and Musk announced that Trump will indeed be reinstated.

Soon after, @realDonaldTrump was once again online, though the former president has yet to tweet. Trump claimed earlier this year that he would not be returning to the platform even if his account was reinstated.

The option to reinstate the former President won with 51.8 percent of the 15,085,458 votes. While the poll was ongoing, Musk said that it was getting one million votes per hour, and also said “bot and troll armies” were responsible for some of the activity. 

While Musk has long indicated he would allow Trump coming back onto the platform, he previously pledged to form a moderation council before reversing any permanent Twitter account bans. On November 18th, Musk reinstated a few accounts, including those belonging to Kathy Griffin and Jordan Peterson. At the time, he said no decision had been made about Trump.

Twitter booted Trump off the platform in early 2021 after he broke rules against inciting violence. He violated Twitter’s civic integrity policy by expressing support for the mob that stormed the Capitol on January 6th last year. His account was initially suspendedfor 12 hours. A couple of days later, in his final days in office, Twitter permanently suspended Trump’s personal account. Trump has been unable to use the platform since, despite his attempts to skirt the ban and a failed lawsuit that sought to have his access restored. It took Musk acquisition for Twitter for Trump to get his account back.

Trump’s return may be as much of a business decision on Musk’s part as much as anything. Earlier this week, a Reuters report suggested that many of Twitter’s heaviest users have moved away from the platform to the likes of Instagram and TikTok. Musk himself has noted that many of the most-followed Twitter accounts don’t tweet often.

For better or worse, Trump is a prominent figure and his tweets commanded attention. Whether advertisers will be glad to see Trump back remains to be seen. Just ahead of officially assuming control of Twitter, Musk sought to soothe any concerns by stating that “Twitter obviously cannot become a free-for-all hellscape, where anything can be said with no consequences!”

In the wake of his actions surrounding January 6th, Meta blocked Trump’s Facebook and Instagram accounts. As things stand, that suspension is set to expire on January 7th, 2023 — just as the 2024 election cycle gets into full swing. 

Since being de-platformed from major services, Trump has turned his attention to smaller social networks, including his own app, Truth Social. Trump had pledged that he wouldn’t return to Twitter, but with 88 million followers there, he commanded an audience almost 22 times the size of the one he has on Truth Social (a platform that, for what it’s worth, Musk has described as “essentially a right-wing echo chamber”).

Twitter has gone through enormous changes since Musk took over the company. He has slashed the headcount by turfing out thousands of employees and contractors, as well as some dissenters. Several top executives are among those who’ve departed. Around 1,200 more are said to have left after refusing to commit to Musk’s vision of a “hardcore” Twitter 2.0 that would require working “long hours at high intensity.” Trump’s return won’t exactly help to steady the ship.

Do Screens Before Bedtime Actually Improve Your Sleep?

Having trouble falling asleep, a writer for Vulture pondered a study from February in the Journal of Sleep Research that “runs refreshingly counter to common sleep-and-screens wisdom.”

For years, science and conventional wisdom have stated unequivocally that looking at a device — like a smartphone, tablet, laptop, or television — before bed is akin to lighting years of your natural life on fire, then letting the flames consume your children, your community, and the very concept of human progress….

Specifically interested in the use of “entertainment media” (streaming services, video games, podcasts) before bed, [the new February study’s] researchers asked a group of 58 adults to keep a sleep diary and found that, if participants consumed entertainment media in the hour before bed, the habit was associated with an earlier bedtime as well as more sleep overall (though the benefits diminished if participants binged for longer than an hour or multitasked on their phones). Essentially, these researchers explored screen use before bed as a form of relaxation rather than a form of self-harm, which is exactly how I and probably 5 billion other people use it — as a way of distracting our minds from the onslaught of material reality just before we drift off to temporary oblivion.

Vulture’s writer interviews Dr. Morgan Ellithorpe, one of the authors of the Journal of Sleep Research study and an assistant professor in the Department of Communication at the University of Delaware who specializes in media psychology.

Dr. Ellithorpe is a proponent of intentional media use as a way to relieve stress, but she tells me that, in her research, she’s found that the worst types of media to absorb before bed are those that have no “stopping point” — Instagram, TikTok, shows designed to be binge-watched. If you intend to binge a show, that might be fine: “Making a plan and sticking to it seems to matter,” she says. We agree that humans are famously bad at that, and that’s where the problems begin. The solution, Dr. Ellithorpe says, is figuring out why we’re on our screens and if that reason is “meaningful.” Are we turning to a screen in order to recover from an eventful day? Because we want something to talk about with our friends? Because we’re seeking, as she puts it, a moment of “hedonic enjoyment”? The key is that you must be able to recognize when that need is fulfilled. Then “you’re likely to have a good experience, and you won’t need to force yourself to stop. But it takes practice.”

Dr. Ellithorpe cites several studies for me to review — on gratification, mood-management theory, selective exposure, and self-determination theory — all of which, to various extents, grapple with the notion that human beings can make decisions to use media for purposeful things. “There’s this push now to realize that people aren’t a monolith, and media uses that seem bad for some people can actually be really good for other people.” Although many researchers like Dr. Ellithorpe and her cohort are onboard with this push, she admits that “the movement has not filtered out to the public yet. So the public is still on this kick of ‘Oh, media’s bad.'”

And that’s a huge part of the issue. “We sabotage ourselves when it comes to benefiting from media because we’ve been taught in our society to feel guilty for spending leisure time with media,” Dr. Ellithorpe says. “The research in this area suggests that people who want to use media to recover from stress, if they then feel bad about doing so, they don’t actually get the benefit from the media use.”

But even Dr. Ellithorpe is prone to unintentional sleep moralizing, saying she is often “bad” and “on her phone two seconds before I turn off the light.” She recommends watching a “low-challenge show” before bed and, like Dr. Kennedy, cites Stranger Things specifically as a dangerous pre-bed content choice because “you have to keep track of all the characters, remember what happened three seasons ago, and it’s emotionally charged. It might be difficult afterward to come down from that and go to bed.” In the end, she suggests watching whatever you want as long as it doesn’t delay your bedtime.

As US Investigates Ticketmaster, Botched Sale of Taylor Swift Tickets Fuels Monopoly Criticisms

Ticketmaster provoked ire with a botched sale of tickets to Taylor Swift’s first concert in five years. NPR reports:
On Thursday afternoon, the day before tickets were due to open to the general public, Ticketmaster announced that the sale had been cancelled altogether due to “extraordinarily high demands on ticketing systems and insufficient remaining ticket inventory to meet that demand.” Taylor Swift broke her silence on Friday in statement on Instagram in which she said it is “excruciating for me to watch mistakes happen with no recourse.” She said there are many reasons people had a hard time getting tickets, and she’s trying to figure out how to improve the situation moving forward. “I’m not going to make excuses for anyone because we asked them, multiple times, if they could handle this kind of demand and we were assured they could,” she wrote, without naming Ticketmaster.

America’s Justice Department “has opened an antitrust investigation into the owner of Ticketmaster,” reports the New York Times. But the investigation “predates the botched sale” and “is focused on whether Live Nation Entertainment has abused its power over the multibillion-dollar live music industry.”

The new investigation is the latest scrutiny of Live Nation Entertainment, which is the product of a merger between Live Nation and Ticketmaster that the Justice Department approved in 2010. That created a giant in the live entertainment business that still has no equals in its reach or power…. The debacle involving Ms. Swiftâ(TM)s concert tickets this week has exacerbated complaints in the music business and in Washington that Live Nationâ(TM)s power has constrained competition and harmed consumers.
Or, as NPR puts it, “The frenzy has brought renewed scrutiny to the giant Ticketmaster, which critics have long accused of abusing its market power at the expense of consumers.”

Would-be concertgoers have complained vocally about recent incidents with near-instant sellouts and skyrocketing prices, and artists like Pearl Jam and Bruce Springsteen have feuded with it over the decades. One common complaint is that there doesn’t seem to be a clear alternative or competitor to Ticketmaster, especially after it merged with concert provider Live Nation in 2010 (a controversial move that required conditional approval from the U.S. Department of Justice).

Now Tennessee’s attorney general, a Republican, is opening a consumer protection investigation into the incident. North Carolina’s attorney general announced on Thursday that his office is investigating Ticketmaster for allegedly violating consumers’ rights and antitrust laws. And multiple Democratic lawmakers are asking questions about the company’s dominance â” not for the first time…. “Taylor Swift’s tour sale is a perfect example of how the Live Nation/Ticketmaster merger harms consumers by creating a near-monopoly,” tweeted Sen. Richard Blumenthal (D-Conn.), one of several lawmakers who has long called for investigation and accountability into the company, especially after becoming a subsidiary of concert behemoth Live Nation.

The article also cites a Thursday statement from Ticketmaster:
The company says that using Verified Fan invite codes has historically helped manage the volume of users visiting the website to buy tickets, though that wasn’t the case on Tuesday. “The staggering number of bot attacks as well as fans who didn’t have invite codes drove unprecedented traffic on our site, resulting in 3.5 billion total system requests â” 4x our previous peak,” it said, adding that it slowed down some sales and pushed back others to stabilize its systems, resulting in longer wait times for some users.

It estimates that about 15% of interactions across the website experienced issues, which it said is “15% too many.”

The Tuesday sale also broke Ticketmaster’s record for most tickets sold for an artist in a single day,” reports People, “selling two million tickets.”

Wickr’s consumer messaging app will shut down next year

Secure messaging platform Wickr is shutting down its consumer-facing app. In a blog post spotted by The Verge, the Amazon-owned company announced it would stop accepting new Wickr Me registrations by the end of the year before ultimately discounting the service altogether on December 31st, 2023. The shutdown won’t affect the AWS and Enterprise versions of Wickr.

“After careful consideration, we will be concentrating Wickr’s focus on securing our business and public sector customers’ data and communications with AWS Wickr and Wickr Enterprise, and have decided to discontinue our consumer product, Wickr Me,” the company said, adding that it was working on developing the capability for Wickr customers to securely communicate with individuals outside of their organization.

The announcement comes following reports that Amazon had been doing little to combat the problem of people using Wickr Me to exchange child sexual abuse material. In June, NBC News, citing court documents and information from law enforcement and activists, said the platform had become a “go-to destination” for those trafficking in that type of content.

Before next year’s shutdown, Wickr said it would share information with users on how to save their data. Thankfully, alternatives aren’t hard to find, with apps like Signal providing robust secure messaging.

Governments vote to retire the leap second by 2035

The days of the leap second creating headaches for software engineers are coming to an end. On Friday, government representatives at the General Conference on Weights and Measures in Paris, France voted nearly unanimously to retire the practice of occasionally adding one second to official clocks (via The New York Times).

Introduced in 1972 as a way to adjust Coordinated Universal Time (UTC) to reconcile discrepancies that can come up between atomic time and observed solar time, the leap second has been the bane of tech companies for decades. In 2012, for instance, Reddit was down for about 40 minutes when the addition of a leap second that year confused the company’s servers. More recently, Cloudflare saw part of its DNS services affected due to a time change in 2016.

Companies like Facebook parent Meta employ a technique called “smearing” to avoid outages whenever the International Earth Rotation and Reference Systems Service adjusts UTC to add a leap second. Earlier this year, the social media giant published a blog post calling for an end to the practice. “Every leap second is a major source of pain for people who manage hardware infrastructures,” Meta said at the time. Part of the push to eliminate the leap second has come as a way to preserve UTC as the world’s official international time.

With this week’s vote, dignitaries from the US, Canada and France called for the practice to end before 2035. Russia voted against the proposal. In the past, the country has sought to delay the demise of the leap second because GLONASS, its global positioning system, incorporates the adjustment – the Global Position System (GPS) operated by the US does not. Felicitas Arias, the former director of the Time Department at the International Bureau of Weights and Measures told Nature the decision may force Russia to launch new satellites.

There’s still another organization that needs to weigh in on the matter before software engineers can breathe a sigh of relief. The International Telecommunications Union, the group responsible for transmitting universal time, will vote on the issue next year. If it moves forward with “Resolution D,” metrologists and astronomers will have until at least 2135 to figure out how to reconcile the atomic and astronomical time scales.

The Creator of Homebrew's Plan To Get Open Source Contributors Paid – Using Blockchain

The creator of the Linux/macOS package manager Homebrew has a new package manager named Tea. But according to Stack Overflow’s podcast, the software also “aims to solve the problem of providing funding for popular open source projects.”

While he is not a crypto bull, Max was inspired with a solution for the open source funding dilemma by his efforts to buy and sell an NFT. A contract written in code and shared in public enforced a rule sending a portion of his proceeds to the digital objects original creator. What if the same funding mechanism could be applied to open source projects? In March of 2022, Max and his co-founder launched Tea, a sort of spirtual successor to Homebrew. It has a lot of new features Max wanted in a package manager, plus a blockchain based approach to ensuring that creators, maintainers, and contributors of open source software can all get paid for their efforts.

You can read Max’s launch post on Tea here and yes, of course there is a white paper.

The paper describes the proposed solution as “a decentralized system for fairly remunerating open-source developers based on their contributions to the entire ecosystem and enacted through the tea incentive algorithm applied across all entries in the tea registry.”

And the launch post calls tea “our revolution against a failing system,” arguing “We’re taking our knowledge of how to make development more efficient and throwing innovations nobody has ever really considered before.

“Package managers haven’t been sexy. Until now. Most importantly, we’re moving the package registry on-chain (relax, we’ll use a low-energy proof of stake chain). This has numerous benefits due to the inherent benefits of blockchain technology.” For starters, decentralized storage will make the packages always-available and immutable, signed by maintainers themselves. But there’s more:
web3 has enabled novel new ways to distribute value, and with our system people who care about the health of the open source ecosystem buy some token and stake it. Periodically, we reward this staking because it is securing our token network. We give a portion of these rewards to the staker and a portion to packages of their choice along with all the dependencies of those packages.
Note that no portion goes to us. We’re not like the other app stores….

tea is the home to a DAO that will ensure the open source maintainers that keep the Internet running are rewarded as they deserve.

An introduction to the white paper adds that in the spirit of the open source movement, “we’re inviting developers, speculators, and enthusiasts alike to contribute to our white paper and help brew the future of the internet. This is our revolutionary undertaking to create equitable openâsource for web3, and we want you to be a part of laying its groundwork.”

Atari's 50th Anniversary Collection Includes 100 Games, Interviews, and Addictive New Titles

Launched last week on the Xbox, PlayStation, Nintendo Switch, and Steam, Atari 50: The Anniversary Collection contains over 100 games, and also “over an hour of exclusive video interviews with key players in the games industry” (according to its web site). Forbes says the compilation “may well be the best game collection ever made.” The Verge says the compilation is “huge, detailed, and does an amazing job of explaining why these games are so important.”

But Ars Technica complains it’s “stuffed with historical filler.”

And yet, “one new game contained in the package won’t let me go…” their reviewer adds. “I’m talking about Vctr Sctr, a retro-style arcade shooter that melds the addictive gameplay of classics like Asteroids and Tempest with modern gameplay concepts.”

As a package, Atari 50: The Anniversary Collection sets a new high-water mark for retro video game compilations. The collection’s “timeline” feature deftly weaves archival materials like design documents and manuals, explanatory context and contemporary quotes from the game’s release, and new video interviews with game creators into an engaging, interactive trip through gaming history.

But while the presentation shines, the games contained within Atari 50 often don’t. Sure, there are a few truly replayable classics on offer here, especially in the games from Atari’s glorious arcade era. That said, the bulk of Atari 50’s selection of over 100 titles feels like filler that just doesn’t hold up from a modern game design perspective. Dozens of “classic” Atari games — from 3-D Tic-Tac-Toe on the Atari 2600 to Missile Command 3D on the Jaguar — boil down to mere historical curiosities that most modern players would be hard-pressed to tolerate for longer than a couple of minutes.

Then there’s Vctr Sctr, one of a handful of “reimagined” games on Atari 50 that attempt to re-create the feel of a classic Atari title with modern hardware and design touches…. More than just the look, Vctr Sctr does a great job capturing and updating what vector games of the early arcade era felt like to play.

Vctr Sctr apparently manages to combine updated versions of Asteroids, Lunar Lander, , and Tempest (in increasingly difficult waves). The article notes it’s just one of six “reimagined” titles in Atari 50, but calls Vctr Sctr “a perfect brain-break game, an excuse to ignore the outside world for a quick, distracting burst of focused, high-energy chaos.

“In that way, it might be Atari 50’s best demonstration of what the classic arcade era was really like.”
