Some news Friday from the Associated Press. "The Biden administration is moving one step closer to developing a central bank digital currency, known as the digital dollar, saying it would help reinforce the U.S. role as a leader in the world financial system." The White House said on Friday that after President Joe Biden issued an executive order in March calling on a variety of agencies to look at ways to regulate digital assets, the agencies came up with nine reports, covering cryptocurrency impacts on financial markets, the environment, innovation and other elements of the economic system.

Treasury Secretary Janet Yellen said one Treasury recommendation is that the U.S. "advance policy and technical work on a potential central bank digital currency, or CBDC, so that the United States is prepared if CBDC is determined to be in the national interest.... Right now, some aspects of our current payment system are too slow or too expensive," Yellen said on a Thursday call with reporters laying out some of the findings of the reports....

According to the Atlantic Council nonpartisan think tank, 105 countries representing more than 95% of global gross domestic product already are exploring or have created a central bank digital currency. The council found that the U.S. and the U.K. are far behind in creating a digital dollar or its equivalent.... Several [U.S. agency] reports will come out in the next weeks and months.

Eswar Prasad, a trade professor at Cornell who studies the digitization of currencies, said Treasury's report "takes a positive view about how a digital dollar might play a useful role in increasing payment options for individuals and businesses" while acknowledging the risks of its development. He said the report sets the stage for the creation of agency regulations and legislation "that can improve the benefit-risk tradeoff associated with cryptocurrencies and related technologies."
A statement from the U.S. White House cautions that the report does not make any decisions "regarding particular design choices for a potential U.S. CBDC system." Instead, the 58-page document analyzes 18 different choices for technical designs, and according to its introductory paragraph, "makes recommendations on how to prepare the U.S. Government for a U.S. CBDC system."

But "it does no make an assessment or recommendation about whether a U.S. CBDC system should be pursued."

"The poles are warming several times faster than the global average," Phys.org reminds us, "causing record smashing heatwaves that were reported earlier this year in both the Arctic and Antarctic. Melting ice and collapsing glaciers at high latitudes would accelerate sea level rise around the planet.

"Fortunately, refreezing the poles by reducing incoming sunlight would be both feasible and remarkably cheap, according to new research published Friday in Environmental Research Communications." Scientists laid out a possible future program whereby high-flying jets would spray microscopic aerosol particles into the atmosphere at latitudes of 60 degrees north and south — roughly Anchorage and the southern tip of Patagonia. If injected at a height of 43,000 feet (above airliner cruising altitudes), these aerosols would slowly drift poleward, slightly shading the surface beneath. "There is widespread and sensible trepidation about deploying aerosols to cool the planet," notes lead author Wake Smith, "but if the risk/benefit equation were to pay off anywhere, it would be at the poles."

Particle injections would be performed seasonally in the long days of the local spring and early summer. The same fleet of jets could service both hemispheres, ferrying to the opposite pole with the change of seasons.

newly designed high-altitude tankers would prove much more efficient. A fleet of roughly 125 such tankers could loft a payload sufficient to cool the regions poleward of 60 degreesN/S by 2 degreesC per year, which would return them close to their pre-industrial average temperatures. Costs are estimated at $11 billion annually — less than one-third the cost of cooling the entire planet by the same 2 degreesC magnitude and a tiny fraction of the cost of reaching net zero emissions.
Smith calls the idea "game-changing" (while also warning it's "not a substitute for decarbonization").

The world's freight-carrying trucks and ships use GPS-based satellite tracking and navigation systems, reports ZDNet. But "Criminals are turning to cheap GPS jamming devices to ransack the cargo on roads and at sea, a problem that's getting worse...." Jammers work by overpowering GPS signals by emitting a signal at the same frequency, just a bit more powerful than the original. The typical jammers used for cargo hijackings are able to jam frequencies from up to 5 miles away rendering GPS tracking and security apparatuses, such as those used by trucking syndicates, totally useless. In Mexico, jammers are used in some 85% of cargo truck thefts. Statistics are harder to come by in the United States, but there can be little doubt the devices are prevalent and widely used. Russia is currently availing itself of the technology to jam commercial planes in Ukraine.

As we've covered, the proliferating commercial drone sector is also prey to attack.... During a light show in Hong Kong in 2018, a jamming device caused 46 drones to fall out of the sky, raising public awareness of the issue.
While the problem is getting worse, the article also notes that companies are developing anti-jamming solutions for drone receivers, "providing protection and increasing the resiliency of GPS devices against jamming attacks.

"By identifying and preventing instances of jamming, fleet operators are able to prevent cargo theft."

The short answers are "yes" and "no." America's Constitution prohibits government intervention into public expression, reports the business-news radio show Marketplace, "protecting free speech and expression "through, for example.... writing, protesting and coding languages like JavaScript, HTML, Python and Perl."

Specifically protecting code started with the 1995 case of cryptographer Daniel Bernstein, who challenged America's "export controls" on encryption (which regulated it like a weapon). But they also spoke to technology lawyer Kendra Albert, a clinical instructor at Harvard Law School's Cyberlaw Clinic, about the specific parameters of how America protects code as a form of expression: Albert: I think that the reality was that the position that code was a form of expression is in fact supported by a long history of First Amendment law. And that it, you know, is very consistent with how we see the First Amendment interpreted across a variety of contexts.... [O]ne of the questions courts ask is whether a regulation or legislation or a government action is specifically targeting speech, or whether the restrictions on speech are incidental, but not the overall intention. And that's actually one of the places you see kind of a lot of these difficulties around code as speech. The nature of many kinds of regulation may mean that they restrict code because of the things that particular forms of software code do in the world. But they weren't specifically meant to restrict the expressive conduct. And courts end up then having to sort of go through a test that was originally developed in the context of someone burning a draft card to figure out — OK, is this regulation, is the burden that it has on this form of expressive speech so significant that we can't regulate in this way? Or is this just not the focus, and the fact that there are some restrictions on speech as a result of the government attempting to regulate something else should not be the focus of the analysis?

Q: Congress and federal agencies as well as some states are looking to tighten regulations around cryptocurrencies and blockchain technology. What role do you think the idea of code as speech will play in this environment moving forward?

Albert: The reality is that the First Amendment is not a total bar to regulation of speech. It requires the government meet a higher standard for regulating certain kinds of speech. That runs, to some extent, in conflict with how people imagine what "code is speech" does as sort of a total restriction on the regulation of software, of code, because it has expressive content. It just means that we treat code similarly to how we treat other forms of expression, and that the government can regulate them under certain circumstances.

The Mars rover Perseverance was the subject of a new NASA briefing Thursday. CNET describes it as a celebration of this year's discovery of organic matter — in June NASA for the first time measured the total amount of organic carbon in Martian rocks — and a celebration of rock samples. (Specifically, the two samples collected from mudstone rock on Wildcat Ridge in Jezero Crater.) The rover's Sherloc instrument investigated the rock. (Sherloc stands for Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals.) "In its analysis of Wildcat Ridge, the Sherloc instrument registered the most abundant organic detections on the mission to date," NASA said.

Scientists are seeing familiar signs in the analysis of Wildcat Ridge. "In the distant past, the sand, mud and salts that now make up the Wildcat Ridge sample were deposited under conditions where life could potentially have thrived," said Perseverance project scientist Ken Farley in a statement. "The fact the organic matter was found in such a sedimentary rock — known for preserving fossils of ancient life here on Earth — is important."

Perseverance isn't equipped to find definitive evidence of ancient microbial life on the red planet. "The reality is the burden of proof for establishing life on another planet is very, very high," said Farley during the press conference. For that, we need to examine Mars rocks up close and in person in Earth labs. Perseverance currently has 12 rock samples on board, including the Wildcat Ridge pieces and samples from another sedimentary delta rock called Skinner Ridge. It also collected igneous rock samples earlier in the mission that point to the impact of long-ago volcanic action in the crater. NASA is so happy with the diversity of samples collected that it's looking into dropping some of the filled tubes off on the surface soon in preparation for the future Mars Sample Return campaign.... The mission is under development. If all goes as planned, those rocks could be here by 2033 .
The hope is that in 2033, Perseverance will meet the lander "and personally deliver the samples," the article quips. But in the meantime, Perseverance "could wander up the crater rim." And there's one more update about the smaller exploration vehicle that Peseverance carried to Mars.

"Its companion Ingenuity helicopter is in good health and expected to take to the air again."

The Economist notes this business cycle is hurting ad revenue for Alphabet's Google and Meta's Facebook."Last quarter Meta reported its first-ever year-on-year decline in revenues. Snap, a smaller rival, is laying off a fifth of its workforce." But for both companies, "the cyclical problem may not be the worst of it," since they're finally facing some real competition.

"They might once have hoped to offset the digital-ad pie's slower growth by grabbing a larger slice of it. No longer." Although the two are together expected to rake in around $300bn in revenues this year, sales of their four biggest rivals in the West will amount to almost a quarter as much... What is more, as digital advertising enters a period of transformation, the challengers look well-placed to increase their gains. The noisiest newcomer to the digital-ad scene is TikTok. In the five years since its launch the short-video app has sucked ad dollars away from Facebook and Instagram, Meta's two biggest properties. So much so that the two social networks are reinventing themselves in the image of their Chinese-owned rival.... But Meta and Google may have more to worry about closer to home, where a trio of American tech firms are loading ever more ads around their main businesses.

Chief among them is Amazon, forecast to take nearly 7% of worldwide digital-ad revenue this year, up from less than 1% just six years ago. The company started reporting details of its ad business only in February, when it revealed sales in 2021 of $31bn. As Benedict Evans, a tech analyst, points out, that is roughly as much as the ad sales of the entire global newspaper industry. Amazon executives now talk of advertising as one of the company's three "engines", alongside retail and cloud computing.

Next in line is Microsoft, expected to quietly take more than 2% of global sales this year — slightly more than TikTok. Its search engine, Bing, has only a small share of the search market, but that market is a gigantic one. Microsoft's social network, LinkedIn, is unglamorous but its business-to-business ads allow it to monetise the time users spend on it at a rate roughly four times that of Facebook, estimates Andrew Lipsman of eMarketer. It generates more revenue than some medium-sized networks including Snap's Snapchat and Twitter.

The most surprising new adman is Apple. The iPhone-maker used to rail against intrusive digital advertising. Now it sells many ads of its own.... As digital ads work their way into more corners of the economy, "a new order is going to materialise", believes Mr Lipsman. He thinks Amazon will overtake Meta in total advertising revenue, possibly within five years.

Randall Munroe does more than draw the online comic strip XKCD. He's also published a funny new speculative science book (following up on his previous New York Times best-seller), promising "short answers, new lists of weird and worrying questions, and some of my favorite answers from the What If site."

From his blog: In What If 2, I answer new questions I've receieved in the years since What If? was released. People have asked about touching exotic materials, traveling across space and time, eating things they shouldn't, and smashing large objects into the Earth. There are questions about lasers, explosions, swingsets, candy, and soup. Several planets are destroyed — one of them by the soup.
But besides launching a new book tour, he's also found some particularly geeky ways to promote the new book. On Thursday Munroe went on a language podcast to ask his own oddball questions — like how to spot an artificial language, and what does the word "it" refer to in the sentence "It's 3pm and hot." He's illustrated a a science-y animated video, and released several self-mocking cartoons.

And of course — answered some more strange science questions.

The Drive reports; Sir Jony Ive — the man designed the original iMac, iPod, iPhone, and iPad during his 22 years as Apple design chief — has claimed new-car buyers will drive demand for physical buttons to return in automotive entertainment systems.

In recent years, car companies such as Tesla and Volkswagen have progressively moved to remove physical switches from their vehicle's interiors, replacing them with 'haptic' touch-sensitive buttons, or moving a majority of the controls into a central touchscreen. Speaking at a panel session at a conference in the US — alongside Apple CEO Tim Cook and Laurene Powell Jobs (widow of Apple co-founder Steve Jobs) — Ive said there are merits to the design of multi-touch screens, but car buyers will demand for physical controls to return.

"I do think there are fabulous affordances with interfaces like, for example, multi-touch [the technology allowing for pinching and zooming on phone screens]," Ive said. "But we do remain physical beings. I think, potentially, the pendulum may swing a little to have interfaces and products that will take more time and are more engaged physically."

When the panel's moderator — journalist Kara Swisher — asked if Ive was referring to cars, the former Apple design boss responded, "for example".
The article also reports that "Apple's secretive autonomous car project is believed to be continuing behind closed doors, with the tech giant reportedly employing 5000 staff members to work on a new electric car."

Long-time Slashdot reader n3hat writes: The BBC reports that a thief has been emptying gym patrons' accounts by stealing their bank card and mobile phone, registering the account to the thief's own mobile, and emptying the victims' bank accounts. The thief works around 2-factor authentication by taking advantage of the victim's phone having been configured to show notifications on the lock screen, so the thief can view the 2FA credential even though they don't have the unlock code.

The article gives instructions on how to disable notifications on the lock screen, for both iPhone and Android.

"Documents obtained by congressional investigators show that oil industry executives privately downplayed their companies' own public messages about efforts to reduce greenhouse gas emissions," reports the New York Times, "and weakened industrywide commitments to push for climate policies...." At Royal Dutch Shell, an October 2020 email sent by an employee, discussing talking points for Shell's president for the United States, said that the company's announcement of a pathway to "net zero" emissions — the point at which the world would no longer be pumping planet-warming gases into the atmosphere — "has nothing to do with our business plans."

These and other documents, reviewed by The New York Times, come from a cache of hundreds of thousands of pages of corporate emails, memos and other files obtained under subpoena as part of an examination by the House Committee on Oversight and Reform into the fossil fuel industry's efforts over the decades to mislead the public about its role in climate change, dismissing evidence that the burning of fossil fuels was driving an increase in global temperatures even as their own scientists warned of a clear link....

"It's well established that these companies actively misled the American public for decades about the risks of climate change," said Rep. Ro Khanna, D-Calif., who spearheaded the investigation with Rep. Carolyn Maloney, D-N.Y., who leads the House committee. "The problem is that they continue to mislead," Khanna said.
The article also points out that at a government hearing last year, oil industry executives "acknowledged that the burning of their products was driving climate change, although none pledged to end their financial support for efforts to block action on climate change, and they said that fossil fuels were here to stay."

"There's a new Joker movie coming out," writes the Verge, "but you might not get a chance to see it because copyright is broken." I'm not talking about Joker: Folie à Deux, the officially sanctioned sequel to the Todd Phillips film Joker. I'm talking about The People's Joker, a crowdfunded Toronto International Film Festival (TIFF) selection that was pulled at the last minute, thanks to unspecified "rights issues." The People's Joker is (as far as I can tell) an extremely loose retelling of the Batman villain's origin story, reinterpreting the Joker as a trans woman trying to break into the mob-like world of Gotham's stand-up comedy scene. Its trailer describes it as "an illegal comic book movie," but its creators more seriously defend it as an unauthorized but legal parody of DC's original character, to the point of (apparently) giving their lawyer a full-screen credit.

I have no idea if The People's Joker is a good movie — thanks to its cancelation, my colleague Andrew Webster couldn't catch it at TIFF. The piece is clearly a provocation designed to thumb its nose at DC's copyright, and DC parent company Warner Bros. hasn't said whether it actually ordered TIFF to cancel showings — it's possible the festival balked or even that Drew did it herself. But despite all that, one thing is very clear: outside a tiny number of corporate behemoths, virtually nobody benefits from shutting down The People's Joker — not the filmmakers, not the public, and not the people who created Gotham City in the first place.

Writer-director Vera Drew says she made The People's Joker partly to test a contemporary truism: that beloved fictional universes are a shared modern mythology, and people draw meaning from them the way that artists once reinterpreted Greek myths or painted Biblical figures. As Drew has put it, "if the purpose of myth is to learn about the human experience and grow and also chart your progress — the hero's journey and all that stuff — let's actually do that earnestly with these characters."
The essay delves into the argument that culture exists for the common good. "It's useful to have a temporary period where artists can maintain control over their work because it helps support them financially and encourages them to make more of it. But the ultimate goal is that art should pass into the public domain and that it should be part of a conversation, with people repurposing it to create their own work...."

In an interview with Comic Book Resources, the filmmaker said the film was protected by both fair use and copyright law. "The only thing that makes it weird in both of those categories is nobody's ever taken characters and IP and really personalized it in this way. So I think that's the thing that really kind of makes it seem a lot more dangerous than I actually think it is. I mean, I get it, look, I put an 'illegal comic book movie' on the poster, but that was just to get your butts in the seats. Mission accomplished."

A statement from the filmmaker on Twitter blames "a media conglomerate that shall remain nameless" for an angry letter pressuring them not to screen the film. (It was ultimately allowed to premiere, but then pulled from later screenings.) They added that they were disappointed since "I went to great lengths with legal counsel to have it fall under parody/fair use," but they made the choice to protect the film festival and the future prospects for a possible return of the movie itself.

"The People's Joker will screen again very soon at several other festivals worldwide."

The Verge's conclusion? "If a law meant to protect artists is leaving weird independent movies in limbo to protect a corporate brand, something has gone deeply wrong."

Long-time Slashdot reader destinyland writes: Today GitHub's official Twitter account asked the ultimate geek-friendly question. "You never forget your first computer. What was yours?"

And within 10 hours they'd gotten 2,700 responses.

Commodore 64, TRS-80, Atari 800, Compaq Presario... People posted names you haven't heard in years, like they were sharing memories of old friends. Gateway 2000, Sony VAIO, Vic-20, Packard Bell... One person just remembered they'd had "some sort of PC that had an orange and black screen with text and QBasic. It couldn't do much more than store recipes and play text based games."

And other memories started to flow. ("Jammed on Commander Keen & Island of Dr. Brain..." "Dammit that Doom game was amazing, can't forget Oregon Trail...")

Sharp PC-4500, Toshiba T3200, Timex Sinclair 1000, NEC PC-8801. Another's first computer was "A really really old HP laptop that has a broken battery!"

My first computer was an IBM PS/2. It had a 2400 baud internal modem. Though in those long-ago days before local internet services, it was really only good for dialing up BBS's. I played chess against a program on a floppy disk that I got from a guy from work.
Can you still remember yours? Share your best memories in the comments.

What was your first computer?

First, a rumor from the blog Phone Arena. "Not to be outdone by Apple and Huawei, Samsung is planning to incorporate satellite connectivity options in its Galaxy phones as well, hints leakster Ricciolo."

But it's not the first rumor we've heard about phone vendors and satellites. "Cringley Predicts Apple is About to Create a Satellite-Based IoT Business ," read the headline in June. Long-time tech pundit Robert X. Cringely predicted that Apple would first offer some limited satellite-based functionality,

But he'd also called those services "proxies for Apple entering — and then dominating — the Internet of Things (IoT) business. "After all, iPhones will give them 1.6 billion points of presence for AirTag detection even on sailboats in the middle of the ocean — or on the South Pole.... Ubiquity (being able to track anything in near real time anywhere on the planet) signals the maturity of IoT, turning it quickly into a $1 TRILLION business — in this case Apple's $1 TRILLION business." And beyond that, "in the longer run Cupertino plans to dis-intermediate the mobile carriers — becoming themselves a satellite-based global phone and data company [and] they will also compete with satellite Internet providers like Starlink, OneWeb, and Amazon's Kuiper."

So how did Cringely react last week when Apple announced "Emergency SOS" messaging for the iPhone 14 and 14 Plus — via communication satellites — when their users are out of range of a cell signals? He began by wondering if Apple was intentionally downplaying the satellite features: They limited their usage case to emergency SOS texts in the USA and Canada, sorta said it would be just for iPhone 14s, and be free for only the first two years. They showed a satellite app and very deliberately tried to make it look difficult to use. They gave no technical details and there was no talk of industry partners.

Yet there were hints of what's to come. We (you and I, based on my previous column) already knew, for example, that ANY iPhone can be made to work with Globalstar. We also knew the deal was with Globalstar, which Apple never mentioned but Globalstar confirmed, more or less, later in the day in an SEC filing. But Apple DID mention Find My and Air Tags, notably saying they'd work through the satellites even without having to first beseech the sky with an app. So the app is less than it seems and Apple's satellite network will quickly find its use for the Internet of Things [Cringely predicts]....

Apple very specifically said nothing about the global reach of Find My and Air Tags. There is no reason why those services can't have immediate global satellite support, given that the notification system is entirely within Apple's ecosystem and is not dependent on 911-type public safety agreements.

Maybe it will take a couple years to cover the world with SOS, but not for Find My, which means not for IoT — a business headed fast toward $1 trillion and will therefore [hypothetically] have a near-immediate impact on Apple's bottom line.
Speculating further, Cringely predicts that Globalstar — which has ended up with vast tracts of licensed spectrum — will eventually be purchased by a larger company. ("If not Apple, maybe Elon Musk.")

And this leads Cringely to yet another prediction. "If Elon can't get Globalstar, he and his partners will push for the regulatory expansion into space of terrestrial 5G licenses, which will probably be successful." This will happen, frankly, whether SpaceX and T-Mobile are successful or not, because AST&Science and its investors AT&T, Verizon and Zodafone need 5G in space, too, to compete with Apple. So there WILL eventually be satellite competition for Apple and I think the International Telecommunication Union will eventually succumb to industry pressure.
And by the end Cringely is also speculating about just how Apple will come up with innovative new satellite designs on a faster schedule...
