In 1972, photo prints that developed before your eyes were "downright magical," argues Fast Company — "and still meaningful today."

A new article at Fast Company points out that while Polaroid went bankrupt twice, and stopped making cameras in 2007, "Then an unexpected thing happened: It turned out that even Polaroid couldn't kill Polaroid." Even as instant photography's eulogies were being written, a band of enthusiasts known as The Impossible Project bought the last Polaroid factory that hadn't been hastily dismantled and started producing film packs again. The task required reformulating its own chemistry from scratch, and it was years until the results reached the vicinity of original Polaroid quality. Fans were very patient.

Eventually, the Impossible Project and Polaroid came under the same ownership, adopted Polaroid as the unified brand, and started making instant cameras again. The new models start at $100 and look a lot like that 1977 OneStep, even when they're adorably miniaturized. It's almost as if Polaroid's years in limbo were a bad dream.... Polaroid and several smaller companies refurbish old models, replacing worn parts and otherwise returning them to optimum performance. Repairing an SX-70 generally involves permanently removing its leather, but replacement skins are available in an array of styles, from the traditional to the psychedelic.

Increasingly, yesteryear's Polaroid cameras are springing back to life in surprising ways. Wisconsin-based Retrospekt not only revives old models, but also encases antique innards in new plastic shells, allowing it to sell branding crossovers such as Malibu Barbie and Pepsi-themed Polaroid cameras. Hong Kong's Mint offers a camera called the SLR670 that's really a restored SX-70 accompanied by a gizmo that plugs into the flash port to allow for manual settings. And Open SX-70 is a project to smarten up the SX-70 by replacing its 1970s circuit board with a tiny Arduino computer.
Other things I learned from the article:

• "Each film pack contained its own battery, so the camera would never run out of juice at an inopportune moment."
• Kodak was forced out of the instant photography market in 1986 by a Polaroid patent infringement suit in which Polaroid won $925 million in damages.
• Edwin Land's "final gambit to revolutionize photography" was 1977's wildly unpopular Polavision instant home movies.
• There's a 1974 ad for the cameras narrated by Laurence Olivier.

New submitter Mononymous writes: Created by Graham Nelson, Inform 7 compiles a powerful object-oriented language resembling English into a working text adventure. Friendly GUIs for various platforms have been open source for many years, but the core compiler remained proprietary. Now, 16 years after its initial freeware release, Nelson has released the source code under the Artistic License 2.0 in a public GitHub repo. Inform 7 is one of the largest "literate programs" ever released.

"We have worked on Overgrowth for 14 years," begins their new announcement. Development first began in 2008, and the game runs on Windows, macOS and Linux platforms. Overgrowth's page on Wikipedia describes the realistic 3D third-person action game as "set in a pre-industrial world of anthropomorphic fighter rabbits, wolves, dogs, cats and rats."

And now, "Just like they did with some earlier games, Wolfire Games have now open sourced the game code for Overgrowth," reports GamingOnLinux. "[J]ump, kick, throw, and slash your way to victory.... The source code is available on GitHub. You can buy it on Humble Store and Steam."

The Overwatch site adds as a bonus that "we're also permanently reducing the game's price by a third worldwide" (so U.S. prices drop from $29.99 to $19.99).

"Only the code is getting open sourced," the announcement notes, "not the art assets or levels, the reason is that we don't want someone to build and sell Overgrowth as their own." Wolfire CEO Max Danielsson explains in a video that "you'll still have to own the game to play and mod it." "What it does mean, however, is that everyone will have full and free access to all our source code, including the engine, project files, scripts, and shaders.

"We'll be releasing it under the Apache 2.0 license, which allows you to do whatever you want with the code, including relicensing and selling it, with very few obligations. We tried to keep this easy...

"This isn't the next big engine. We don't intend to compete with any other great open source game engines like Godot, which is a great option if you're looking for a general-purpose game engine. But if you're interested in looking at what shipped game code can look like, want to look at specific code, like the procedural animation system, or if you're an Overgrowth modder who wants to make an involved total conversion mod, then this is for you.
"We have wanted to open source Overgrowth for a long time," says the announcement on Wolfire's site, "and we are incredibly grateful to our team and community for making this happen.

"We are excited to see what people do with this code and we look forward to the spirit of Overgrowth living on for another 14 years."

Bill Gates shares a statistic about the COVID-19 pandemic. "If we'd been able to stop it within 100 days, we would've saved over 98% of the lives." "Viruses spread exponentially, and so if you get in there when the infection rate is fairly small, you can actually stop the spread."
In a new TED talk, Gates argues that we did learn a lot from this pandemic — enough to build a prevention system for next time. "Covid 19 can be the last pandemic if we take the right steps." But the answer isn't vaccines. "We also need vaccines, but we want to stop the outbreak before we have to do a global vaccination campaign." And then Gates points out that currently it could take months to get resources to a low-income country experiencing an outbreak.

Read on for Slashdot's report on Gates' proposed solution — and how he feels about his own prominence in anti-vaccine misinformation.

Lenovo has released security updates for more than 100 laptop models to fix critical vulnerabilities that make it possible for advanced hackers to surreptitiously install malicious firmware that can be next to impossible to remove or, in some cases, to detect. Ars Technica reports: Three vulnerabilities affecting more than 1 million laptops can give hackers the ability to modify a computer's UEFI. Short for Unified Extensible Firmware Interface, the UEFI is the software that bridges a computer's device firmware with its operating system. As the first piece of software to run when virtually any modern machine is turned on, it's the initial link in the security chain. Because the UEFI resides in a flash chip on the motherboard, infections are difficult to detect and even harder to remove.

Two of the vulnerabilities -- tracked as CVE-2021-3971 and CVE-2021-3972 -- reside in UEFI firmware drivers intended for use only during the manufacturing process of Lenovo consumer notebooks. Lenovo engineers inadvertently included the drivers in the production BIOS images without being properly deactivated. Hackers can exploit these buggy drivers to disable protections, including UEFI secure boot, BIOS control register bits, and protected range register, which are baked into the serial peripheral interface (SPI) and designed to prevent unauthorized changes to the firmware it runs. After discovering and analyzing the vulnerabilities, researchers from security firm ESET found a third vulnerability, CVE-2021-3970. It allows hackers to run malicious firmware when a machine is put into system management mode, a high-privilege operating mode typically used by hardware manufacturers for low-level system management. "All three of the Lenovo vulnerabilities discovered by ESET require local access, meaning that the attacker must already have control over the vulnerable machine with unfettered privileges," notes Ars Technica's Dan Goodin. "The bar for that kind of access is high and would likely require exploiting one or more critical other vulnerabilities elsewhere that would already put a user at considerable risk."

Still, it's worth looking to see if you have an affected model and, if so, patch your computer as soon as possible.

"It was one of the most eagerly awaited scientific announcements of all time, and it pitted the world of faith against the world of rational thought, under the glare of the media," remembers the Guardian. So when cutting-edge carbon-14 tests found that the Shroud of Turin was a forgery, it seemed like the final chapter for a relic that had been revered for centuries as the cloth in which Christ's body had been wrapped when he supposedly rose from the dead at the first Easter almost 2,000 years ago.

But one man — David Rolfe, a film-maker whose documentary The Silent Witness had brought the shroud into the public eye in modern times, and who had converted to Christianity as a result of his research — wasn't prepared to give up on it. He was convinced the carbon dating, carried out in 1988 under the direction of the British Museum and Oxford University, had been flawed. And now he claims he has the evidence to prove it. This week sees the release of a new film, Who Can He Be?, in which Rolfe argues that, far from the shroud being a definite dud, new discoveries in the past few years have again opened the question of its authenticity. So convinced is Rolfe that he's issuing a challenge worth $1m to the British Museum. "If ... they believe the shroud is a medieval forgery, I call on them to repeat the exercise, and create something similar today," he says....

The sample used for the tests, Rolfe argues in his new film, was too small and taken from a corner where the shroud was likely to have been repaired over the centuries....

When it comes to the carbon dating, he's certainly not alone in his scepticism. Barrie M Schwortz, a photographer who documented the shroud in 1978, says "murky" would be a good word to describe the events of 1988. "Today there are at least six peer-reviewed scientific articles that challenge the results of the carbon dating," he says. In his view, the players involved were in a hurry to get the job done, because they wanted to get carbon dating on the map. "Those tests made it a household name, and today it's used widely in archaeology," he says....

The British Museum is less willing to get involved this time around. "Any current questions about the shroud would be best put to those who currently care for it in the royal chapel of the cathedral of Turin," a spokesperson said.

"The U.S. Space Command announced this week that it determined a 2014 meteor hit that hit Earth was from outside the solar system," reports CBS News. "The meteor streaked across the sky off the coast of Manus Island, Papua New Guinea three years earlier than what was believed to be the first confirmed interstellar object detected entering our solar system."

After Oumuamua was spotted in 2017, the interstellar comet Borisov appeared in 2019 — discovered in Crimea, Ukraine at a "personal observatory" built by amateur astronomer Gennadiy Borisov"

But CBS notes that despite their theory about a first interstellar meteor in 2014, the two Harvard astronomers — Dr. Amir Siraj and Dr. Abraham Loeb — "had trouble getting their paper published, because they used classified information from the government." Specifically, data from a classified U.S. government satellite designed to detect foreign missiles... The meteor was unusual because of its very high speed and unusual direction — which suggested it came from interstellar space.... Any space object traveling more than about 42 kilometers per second may come from interstellar space. The data showed the 2014 Manus Island fireball hit the Earth's atmosphere at about 45 kilometers per second, which was "very promising" in identifying it as interstellar, Siraj said....

After more research and help from other scientists, including classified information from the government about the accuracy or level of precision of the data, Siraj and Loeb determined with 99.999% certainty the object was interstellar. But their paper on the finding was being turned down, because the pair only had a private conversation with an anonymous U.S. government employee to confirm the accuracy of the data.
"We had thought this was a lost cause," Dr. Siraj told the New York Times — which couldn't resist adding that "it turned out, the truth was out there." Last month, the U.S. Space Command released a memo to NASA scientists that stated the data from the missile warning satellites' sensors "was sufficiently accurate to indicate an interstellar trajectory" for the meteor. The publication of the memo was the culmination of a three-year effort by Siraj and a well-known Harvard astronomer, Avi Loeb.

Many scientists, including those at NASA, say that the military still has not released enough data to confirm the interstellar origins of the space rock, and a spokesperson said Space Command would defer to other authorities on the question.

But it wasn't the only information about meteors to be released. The military also handed NASA decades of secret military data on the brightness of hundreds of other fireballs, or bolides. "It's an unusual degree of visibility of a set of data coming from that world," said Matt Daniels, assistant director for space security at the White House's Office of Science and Technology Policy, who worked on the data release. "We're in this renewed period of excitement and activity in space programs generally, and in the midst of that, I think thoughtful leaders in multiple places said, 'you know, now is a good time to do this.'"
The Times notes that data from classified military satellites "could also aid NASA in its federally assigned role as defender of planet Earth from killer asteroids. And that is the goal of a new agreement with the U.S. Space Force that aims to help NASA's Planetary Defense Coordination Office better understand what happens when space rocks reach the atmosphere." Sharing sensitive military satellite data with astronomers has led to significant scientific discoveries in the past.

A group of satellites deployed in the 1960s by the United States to detect covert detonations of nuclear weapons on Earth accidentally became the key instruments used to make the first detection of extraterrestrial gamma ray bursts. The bursts showed up on the satellites, code-named Vela, as single bursts of energy, confusing analysts at Los Alamos who later declassified the data in a 1973 paper that spurred academic debate about the bursts' origins....

A core reason for Space Force's increasing ties with NASA has centered on the agency's congressional mandate to detect nearly all asteroids that could threaten the Earth. When NASA signed an agreement in 2020 to strengthen ties with Space Force, the agency acknowledged it had fallen behind in its asteroid-tracking efforts and would need Pentagon resources to carry out its planetary defense mission.

Richard Stallman celebrated his 69th birthday last month. And Wednesday, he gave a 92-minute presentation called "The State of the Free Software Movement."

Stallman began by thanking everyone who's contributed to free software, and encouraged others who want to help to visit gnu.org/help. "The Free Software movement is universal, and morally should not exclude anyone. Because even though there are crimes that should be punished, cutting off someone from contributing to free software punishes the world. Not that person."

And then he began by noting some things that have gotten better in the free software movement, including big improvements in projects like GNU Emacs when displaying external packages. (And in addition, "GNU Health now has a hospital management facility, which should make it applicable to a lot more medical organizations so they can switch to free software. And [Skype alternative] GNU Jami got a big upgrade.")

What's getting worse? Well, the libre-booted machines that we have are getting older and scarcer. Finding a way to support something new is difficult, because Intel and AMD are both designing their hardware to subjugate people. If they were basically haters of the public, it would be hard for them to do it much worse than they're doing.

And Macintoshes are moving towards being jails, like the iMonsters. It's getting harder for users to install even their own programs to run them. And this of course should be illegal. It should be illegal to sell a computer that doesn't let users install software of their own from source code. And probably shouldn't allow the computer to stop you from installing binaries that you get from others either, even though it's true in cases like that, you're doing it at your own risk. But tying people down, strapping them into their chairs so that they can't do anything that hurts themselves -- makes things worse, not better. There are other systems where you can find ways to trust people, that don't depend on being under the power of a giant company.

We've seen problems sometimes where supported old hardware gets de-supported because somebody doesn't think it's important any more — it's so old, how could that matter? But there are reasons...why old hardware sometimes remains very important, and people who aren't thinking about this issue might not realize that...

Stallman also had some advice for students required by their schools to use non-free software like Zoom for their remote learning. "If you have to use a non-free program, there's one last thing... which is to say in each class session, 'I am bitterly ashamed of the fact that I'm using Zoom for this class.' Just that. It's a few seconds. But say it each time.... And over time, the fact that this is really important to you will sink in."

And then halfway through, Stallman began taking questions from the audience...

An anonymous reader quotes a report from the BBC: Researchers have rejuvenated a 53-year-old woman's skin cells so they are the equivalent of a 23-year-old's. [...] The scientists in Cambridge believe that they can do the same thing with other tissues in the body. The head of the team, Prof Wolf Reik, of the Babraham Institute in Cambridge, told BBC News that he hoped that the technique could eventually be used to keep people healthier for longer as they grow older. [...] Prof Reich stressed though that the work, which has been published in the journal eLife, was at a very early stage. He said that there were several scientific issues to overcome before it could move out of his lab and into the clinic. But he said that demonstrating for the first time that cell rejuvenation is possible was a critical step forward.

Prof Reik's team used [a method, called iPS, that involves adding chemicals to adult cells to turn them into stem cells] on 53-year-old skin cells. But they cut short the chemical bath from 50 days to around 12. Dr Dilgeet Gill was astonished to find that the cells had not turned into embryonic stem cells -- but had rejuvenated into skin cells that looked and behaved as if they came from a 23-year old. He said: "I remember the day I got the results back and I didn't quite believe that some of the cells were 30 years younger than they were supposed to be. It was a very exciting day!"

The technique cannot immediately be translated to the clinic because the iPS method increases the risk of cancers. But Prof Reik was confident that now it was known that it is possible to rejuvenate cells, his team could find an alternative, safer method. "The long-term aim is to extend the human health span, rather than the lifespan, so that people can get older in a healthier way," he said. Prof Reik says some of the first applications could be to develop medicines to rejuvenate skin in older people in parts of the body where they have been cut or burned -- as a way to speed up healing. The researchers have demonstrated that this is possible in principle by showing that their rejuvenated skin cells move more quickly in experiments simulating a wound. The next step is to see if the technology will work on other tissues such as muscle, liver and blood cells.

waspleg writes: More than 200 long-time Wikipedia editors have requested that the Wikimedia Foundation stop accepting cryptocurrency donations. The foundation received crypto donations worth about $130,000 in the most recent fiscal year -- less than 0.1 percent of the foundation's revenue, which topped $150 million last year. In her proposal for the Wikimedia Foundation, GorillaWarfare added that 'Bitcoin and Ethereum are the two most highly used cryptocurrencies, and are both proof-of-work, using an enormous amount of energy.' According to one widely cited estimate, the bitcoin network consumes around 200 TWh of energy per year. That's about as much energy as is consumed by 70 million people in Thailand. And it works out to around 2,000 kWh per bitcoin transaction.

Bitcoin defenders countered that bitcoin's energy usage is driven by its mining process, which consumes about the same amount of energy regardless of the number of transactions. So accepting any given bitcoin donation won't necessarily lead to more carbon emissions. But cryptocurrency critics argued that Wikimedia's de facto endorsement of cryptocurrencies may help to push up their price. And the more expensive bitcoin is, the more energy miners will devote to creating new ones. If the foundation complies with the community's request, it wouldn't be the first organization to stop using cryptocurrencies due to environmental concerns. Earlier this month, the Mozilla Foundation announced it would stop accepting cryptocurrencies that use the energy-intensive proof-of-work consensus process. These include bitcoin and ether -- though the latter is expected to convert to a proof-of-stake model in the future.

An anonymous reader quotes a report from Ars Technica: The mysterious Antikythera mechanism -- an ancient device believed to have been used for tracking the heavens -- has fascinated scientists and the public alike since it was first recovered from a shipwreck over a century ago. Much progress has been made in recent years to reconstruct the surviving fragments and learn more about how the mechanism might have been used. And now, members of a team of Greek researchers believe they have pinpointed the start date for the Antikythera mechanism, according to a preprint posted to the physics arXiv repository. Knowing that "day zero" is critical to ensuring the accuracy of the device.

"Any measuring system, from a thermometer to the Antikythera mechanism, needs a calibration in order to [perform] its calculations correctly," co-author Aristeidis Voulgaris of the Thessaloniki Directorate of Culture and Tourism in Greece told New Scientist. "Of course it wouldn't have been perfect -- it's not a digital computer, it's gears -- but it would have been very good at predicting solar and lunar eclipses." [...] In 1951, a British science historian named Derek J. de Solla Price began investigating the theoretical workings of the device. Based on X-ray and gamma ray photographs of the fragments, Price and physicist Charalambos Karakalos published a 70-page paper in 1959 in the Transactions of the American Philosophical Society. Based on those images, they hypothesized that the mechanism had been used to calculate the motions of stars and planets -- making it the first known analog computer. [...]

Voulgaris and his co-authors based their new analysis on a 223-month cycle called a Saros, represented by a spiral inset on the back of the device. The cycle covers the time it takes for the Sun, Moon, and Earth to return to their same positions and includes associated solar and lunar eclipses. Given our current knowledge about how the device likely functioned, as well as the inscriptions, the team believed the start date would coincide with an annular solar eclipse. [...] "The eclipse predictions on the [device's back] contain enough astronomical information to demonstrate conclusively that the 18-year series of lunar and solar eclipse predictions started in 204 BCE," Alexander Jones of New York University told New Scientist, adding that there have been four independent calculations of this. "The reason such a dating is possible is because the Saros period is not a highly accurate equation of lunar and solar periodicities, so every time you push forward by 223 lunar months the quality of the prediction degrades."

Slashdot reader alaskana98 writes: In what has become a stubborn sibling to the 'Face on Mars' phenomenon, the legend of the Dark Knight alien satellite has persisted for years and is the fascinating story of a seemingly mundane NASA photo tied together with reports of seemingly mysterious radio waves captured in the early days of radio, all combining to make the ultimate space conspiracy theory.

It goes something like this — an ancient alien space probe, dubbed the 'Dark Knight, has been long orbiting Earth and covertly monitoring its blissfully unaware inhabitants for mysterious purposes for roughly 10,000 years. Flash forward to the 1899, where technological pioneer Nikola Tesla, while experimenting with radio technology in his Colorado laboratory supposedly captured mysterious emanations from an unearthly object. Later in the 1920's, Norwegian engineer Jørgen Hals found that radio signals he transmitted were being echoed back to him a few seconds later, something called 'long delayed echoes' — still unexplained to this day. It has been proposed that these echoes were signals being relayed back to earth by something called a 'Bracewell Probe', a hypothetical automated spacecraft sent out with the goal of making contact with other intelligent species.

Flash forward to 1998, an unassuming photo from the STS-88 mission in 1998 to attach the U.S. module to the Russian portion of the ISS captured a tantalizing glimpse of an unnaturally geometric shape menacingly loitering toward the bottom of the frame. To true believers, this was evidence of an ancient probe keeping tabs on the earthly locals. Combined, these disparate events swirl together to create the stuff of dreams for the ardent conspiracy theorist and even the causal sci-fi buff. Ultimately, the object in the STS photo was most likely a thermal cover. The radio waves Tesla heard? Likely natural radio emisions of a natural or terestial source.

Space.com took a deep dive into this myth and explored how it — and the - dark knight myth has taken a hold on the imaginations of those who find themselves peering out into the inky blackness of the night and wonder to themselves "are we being watched from above"?

Ars Technica looks at the "in-space propulsion company" Impulse Space, which just announced $20 million in seed funding this week to help it build something called an "orbital transfer vehicle."

The company was founded by rocket scientist Tom Mueller, who the article describes as the first employee hired by Elon Musk for SpaceX, leading the development of SpaceX's Merlin rocket engine.

Impulse Space is apparently positioning itself for its own role in a future with lots of reusable rockets and cheaper launch costs: Founded last September, Impulse Space will initially seek to provide "last mile" delivery services for satellites launched as part of rideshare missions, likely including on SpaceX's workhorse Falcon 9 rocket.... While the company is not ready to discuss its specific technology, the goal is to deliver the most delta-V capability [velocity from fuel-burning] in the most efficient manner.

Impulse Space released a teaser video on this earlier this month. [The video's title? "Hello, Solar System...!" And it concludes with the words "Big things have small beginings."]

Impulse Space will seek to complement launch services with sustainable delivery in space, using green propellants and having vehicles with de-orbit capability. Barry Matsumori, who recently joined as the company's chief operating officer, said the company recognizes that if tens or hundreds of satellites will be launching on these heavy-lift rockets, they're going to need to reach different orbits and have different purposes... The company's initial business strategy involves low Earth orbit, but it envisions the need for sustainable transportation from the Earth to the Moon — in the form of a tug — and the storage and movement of propellant in both low Earth orbit and the lunar environment.

Once a company mines a space resource, after all, it will have to go somewhere.

An anonymous reader quotes a report from VentureBeat: Anyone who has worked in the financial services sector will at least be aware of Bloomberg Terminal, a research, data and analytics platform used to garner real-time insights on the financial markets. Bloomberg Terminal has emerged as something of an industry standard, used by more than 300,000 people at just about every major financial and investment-related corporation globally -- but it costs north of $20,000 per user each year to license, a fee that is prohibitively high for many organizations. This is something that OpenBB has set out to tackle, by democratizing an industry that has been "dominated by monopolistic and proprietary incumbents" for the past four decades -- and it's doing so with an entirely open source approach.

After launching initially last year as an open source investment research terminal called Gamestonk Terminal, the founding team, Didier Lopes, Artem Veremey, and James Maslek, were approached by OSS Capital to make an investment and build a commercial company on top of the terminal. And so OpenBB is formally launching this week with $8.5 million in funding from OSS Capital, with contributions from notable angel investors including early Google backer Ram Shriram, entrepreneur and investor Naval Ravikant, and Elad Gil. The newly named OpenBB Terminal is very much an alpha-stage product, one that's aimed at the more technically minded. It's pitched as a "Python-based integrated environment for investment research," allowing any trader to access data science and machine learning smarts to unpack raw, unrefined data.

OpenBB hopes that its open source credentials, and foundations in Python, will position it to win over many new users -- flexibility is the name of the game. [...] Indeed, being open source means that the broader community can add their own flavors to the OpenBB mix -- by way of example, one contributor who was interested in the foreign currency exchange market (Forex) added an Oanda integration to the project. Given that the entire source code is available for anyone to modify, companies can create their own version of the terminal with customizations that suit their niche use-cases. If they want to remove all the clutter and work purely with one type of asset, they can create a sort of light-weight version of the terminal with a much narrower focus on Forex, or cryptocurrency, for example. But who is the actual intended end-user, exactly? In truth, it could be anyone from regional investment banks and hedge funds, to venture capitalists, family offices, and mutual funds. Although the product isn't quite at that stage yet -- that is where the initial seed capital enters the fray. It's all about building the product into something that could serve a potentially large market. OpenBB Terminal will be free for now, but "there will be a concerted push to monetize it," adds VentureBeat. "Some ideas currently under consideration include building a 'slick 21st century UI,' as well as developing a software-as-a-service (SaaS) model, where OpenBB serves up the computational power to run machine learning models on vast amounts of data."

"OpenBB is also exploring ways to build bridges between data sources and investors."

Science magazine explores how actual scientists feel about Twitter: "I like that there's a low bar to entry [on Twitter] — I can put something out and see how other scientists are thinking of a problem, people who have a different skill set than mine," says biostatistician Natalie Dean of Emory University, whose Twitter account has some 138,000 followers. But the pandemic has also helped demonstrate the limitations of social media. It can be difficult, for example, for scientists to be heard over the cacophony of messages on Twitter — some 500 million each day. And although some scientists have used the platform to elevate their online presence, that has rarely translated into concrete professional rewards....

[A]s the pandemic exploded and researchers sought to pump out information to each other and an eager public, many saw advantages to Twitter. Its vast reach became a draw: more than 200 million active daily users, including an estimated one-quarter of U.S. adults, according to the Pew Research Center. This allows scientists to use a single platform to share research findings with both peers and the public and to foster open discussions... One result is that the platform has carried posts about a majority of the total COVID-19 literature — about 51% of journal articles on pandemic research had been mentioned in at least one tweet through May 2021, according to a report by the Research on Research Institute (RoRI). That exceeds the number cited in scholarly articles or mentioned in several other communications venues, including news stories, Facebook, YouTube, Wikipedia, blogs, and policy documents. And it's well above the level before the pandemic, when studies found that just 10% to 30% of papers on any scientific topic got a mention on Twitter....

But an emerging body of research about tweeting suggests that, overall, scientists often struggle to be heard on social media. One study, for example, found tweets containing links to scholarly papers typically get little engagement. Of 1.1 million such tweets about papers published before the pandemic, half drew no clicks, and an additional 22% attracted just one or two, according to a 2021 paper in the Journal of the Association for Information Science and Technology.
An information scientist at the University of Ottawa tells the magazine that "We are really not at the point where we want to get, which is, ideally, seeing the impact of research on the greater good of society."

Thanks to Slashdot reader sciencehabit for sharing the story...

Back in 1987 Alexander Trevor worked with the GIF format's creator, Steve Wilhite, at CompuServe. 35 years later Fast Company tech editor Harry McCracken (also Slashdot reader harrymcc) located Trevor for the inside story: Wilhite did not come up with the GIF format in order to launch a billion memes. It was 1987, and he was a software engineer at CompuServe, the most important online service until an upstart called America Online took off in the 1990s. And he developed the format in response to a request from CompuServe executive Alexander "Sandy" Trevor. (Trevor's most legendary contribution to CompuServe was not instigating GIF: He also invented the service's CB Simulator — the first consumer chat rooms and one of the earliest manifestation of social networking, period. That one he coded himself as a weekend project in 1980.)

GIF came to be because online services such as CompuServe were getting more graphical, but the computer makers of the time — such as Apple, Commodore, and IBM — all had their own proprietary image types. "We didn't want to have to put up images in 79 different formats," explains Trevor. CompuServe needed one universal graphics format.

Even though the World Wide Web and digital cameras were still in the future, work was already underway on the image format that came to be known as JPEG. But it wasn't optimized for CompuServe's needs: For example, stock charts and weather graphics didn't render crisply. So Trevor asked Wilhite to create an image file type that looked good and downloaded quickly at a time when a 2,400 bits-per-second dial-up modem was considered torrid. Reading a technical journal, Wilhite came across a discussion of an efficient compression technique known as LZW for its creators — Abraham Limpel, Jacob Ziv, and Terry Welch. It turned out to be an ideal foundation for what CompuServe was trying to build, and allowed GIF to pack a lot of image information into as few bytes as possible. (Much later, computing giant Unisys, which gained a patent for LZW, threatened companies that used it with lawsuits, leading to a licensing agreement with CompuServe and the creation of the patent-free PNG image format.)

GIF officially debuted on June 15, 1987. "It met my requirements, and it was extremely useful for CompuServe," says Trevor....

GIF was also versatile, offering the ability to store the multiple pictures that made it handy for creating mini-movies as well as static images. And it spread beyond CompuServe, showing up in Mosaic, the first graphical web browser, and then in Netscape Navigator. The latter browser gave GIFs the ability to run in an infinite loop, a crucial feature that only added to their hypnotic quality. Seeing cartoon hamsters dance for a split second is no big whoop, but watching them shake their booties endlessly was just one of many cultural moments that GIFs have given us.

Wikipedia points out that America's two largest-circulation publications are the two magazine sent out to over 38 million members of massive non-profit AARP (originally the American Association of Retired Persons).

It's now starting its own social network to compete with Facebook (which according to a recent survey is being used by over 72 million Americans over the age of 50), Ars Technica reports: The nonprofit funded the creation of Senior Planet Community, a social media network that encourages users to join pre-existing groups around shared interests, including gardening, travel, fitness, food, and technology. In that way, it feels more like a pared-down version of Reddit or a small collection of forums....

Besides its focus on the 50-plus set, Senior Planet Community stands apart from Facebook in that it's not commercial. The site has no advertising or membership fees. Unless the cost to run the site grows substantially, that probably won't present much of a problem. AARP isn't saying how much it has put into Senior Planet Community, but the organization is famously well-capitalized, with $2.3 billion in net assets and $1.7 billion in revenue in 2020.

At present, the site is bare-bones when compared with Facebook. There's no mobile app yet, though OATS [the affiliate organization that built the social network] says it hopes to develop one. The site is mobile-friendly at least, and all the requisite features are there, including groups, photo sharing, @-mentions, notifications, and direct messaging. As with all social networks, a looming question is how Senior Planet Community will handle moderation. The site has a relatively extensive list of "house rules" that encourages users to "be courteous" and "cite your sources." Posts about politics aren't forbidden, but the rules say posts can't stray off-topic, and users can't "attack individuals, social, ethnic, or political groups and figures." Users can report posts they think violate the rules. Currently, the user base is relatively small, so policing it should be straightforward.

"The moderating team keeps an eye on all comments, posts, and updates added to the platform from the backend.... " Suzanne Myklebust, OATS's director of communications, told Ars.

An anonymous reader quotes a report from Slate.com: On March 1, after a week of horror in Ukraine, reports came out that Russia's censorship office had threatened to block Russian Wikipedia. A 32-year-old who asked to be called Alexander soon made a plan to download a local copy of Russian-language Wikipedia to keep with him in eastern Russia. "I did it just in case," he told me over Instagram Messenger before sharing that he and his wife are "working on moving to another country" with their two dogs, Prime and Shaggy. (Instagram has been blocked in Russia, but many continue to access it using virtual private networks. On Monday, the Russian government officially declared Facebook and Instagram "extremist organizations.")

Alexander wasn't the only Russian citizen to make a local copy of Wikipedia. Data suggests that after the threats of censorship, Russians started torrenting Wikipedia in droves. Currently, Russia is the country with the most Wikipedia downloads—by a landslide. Before the invasion, it rarely broke the top 10, but after the Feb. 24 invasion of Ukraine, it has kept a solid hold on first place. The 29-gigabyte file that contains a downloadable Russian-language Wikipedia was downloaded a whopping 105,889 times during the first half of March, which is a more than 4,000 percent increase compared with the first half of January. According to Stephane Coillet-Matillon, who leads Kiwix, the organization that facilitates these downloads, Russian downloads now constitute 42 percent of all traffic on Kiwix servers, up from just 2 percent in 2021. "We had something similar back in 2017 when Turkey blocked Wikipedia," he said, "but this one is just another dimension." "Wikipedia routinely makes a dump of its databases available publicly, which Kiwix compresses into an archive so it can be more easily shared," adds Slate. "The entirety of English Wikipedia, from 'List of Informally Named Dinosaurs' to 'Floor' to 'Skunks as Pets' and everything in between, is 87 GB with pictures or 47 GB without. Russian-language Wikipedia is even smaller, continuing 1.8 million articles compared with English Wikipedia's 6.4 million."

Microsoft says they are investigating claims that the Lapsus$ data extortion hacking group breached their internal Azure DevOps source code repositories and stolen data. BleepingComputer reports: Unlike many extortion groups we read about today, Lapsus$ does not deploy ransomware on their victim's devices. Instead, they target the source code repositories for large companies, steal their proprietary data, and then attempt to ransom that data back to the company for millions of dollars. While it is not known if the extortion group has successfully ransomed stolen data, Lapsus has gained notoriety over the past months for their confirmed attacks against NVIDIA, Samsung, Vodafone, Ubisoft, and Mercado Libre. Unfortunately, Lapsus$ has a good track record, with their claims of attacks on other companies later confirmed to be true.

While the leaking of source code makes it easier to find vulnerabilities in a company's software, Microsoft has previously stated that leaked source code does not create an elevation of risk. Microsoft says that their threat model assumes that threat actors already understand how their software works, whether through reverse engineering or previous source code leaks. "At Microsoft, we have an inner source approach -- the use of open source software development best practices and an open source-like culture -- to making source code viewable within Microsoft. This means we do not rely on the secrecy of source code for the security of products, and our threat models assume that attackers have knowledge of source code," explained Microsoft in a blog post about the SolarWinds attackers gaining access to their source code. "So viewing source code isn't tied to elevation of risk." However, source code repositories also commonly contain access tokens, credentials, API keys, and even code signing certificates.

Slashdot reader mmanciop reminded us that Ubuntu released a new version of its "circle of friends" logo this week (which its designer says gives it "a more contemporary look and feel.")

From the Ubuntu blog: We proudly present to you the transformation of the Circle of Friends logo for Ubuntu. The new logo isn't a revolution; rather, it's an evolution of the Circle of Friends. As you can see at the top of the post, the classic white-on-orange colour scheme hasn't changed. But the new version sports sleek lines which bind the Circle of Friends even more closely together.

While it is important to have a respectful continuity with the previous Circle of Friends, the updated version is leaner, more focused, more sophisticated. It also makes a little more sense that the heads are now inside the circle, facing each other and connecting more directly. The rectangular orange tag is a break from the conventional square or circle, as it allows for the boldness of the orange to express itself and provides a recognisable colourful mark across media. Finally, the logo moves from a tiny superscript to a large, dynamic and leading presence.

Some might wonder why we had to touch the Ubuntu logo at all. As one can imagine, it is a daunting honour to work on something so many of us have such a strong connection to. But in the end, a logo should match what it represents. Similar to how Ubuntu continues to evolve and adapt to new uses in technology, its logo should follow suit to encapsulate and reflect such ongoing change.
For comparison, here's the original logo.

Share your reactions in the comments. (For example, how do you think it compares to other logos?) Do you like it more or less than, say, the logo for Raku?
