What happened after Russia blocked 80 million users of Instagram? Reuters reports: A black and white, melancholy alternative to Instagram that asks users to post sad pictures of themselves may launch in Russia this week, its creators said, to express sadness at the loss of popular services such as the U.S. photo sharing platform.... Although people can still sometimes access [Instagram] using a Virtual Private Network, domestic alternatives have started appearing, the latest being 'Grustnogram', or 'Sadgram' in English. "Post sad pictures of yourself, show this to your sad friends, be sad together," a message on the platform's website read.... "We are very sad that many high quality and popular services are stopping their work in Russia for various reasons," Afisha Daily quoted Alexander Tokarev, one of the service's founders as saying. "We created Grustnogram to grieve about this together and support each other." Insider looks at the larger landscape now for Russia's social media apps: Rossgram joins a slate of Russian versions of major platforms that seek to mimic larger and more popular social media companies, resulting in a landscape of Russian knockoffs that often struggle to attract users while raising questions about how much access the Kremlin has to users' data.... Russia has been trying to coax internet users to turn to its own versions of popular sites, such as YouTube knockoff RuTube, for years. Authorities this year offered online creators the equivalent of $1,700 a month to move their content to RuTube, according to Coda Story, attempting to make up for its minuscule audience. A 2021 report by the Levada Center, an independent polling organization, found that YouTube is used by 37% of Russians, Instagram by 34%, and TikTok by 16%. But some native platforms hold influence too. Out of Russia's 70 million active social media users, according to research by Linkfluence, a market research platform, 83% use a social media platform similar to Facebook called VKontakte, and 55% use another called OdnoKlassniki. According to Alyssa Demus, an associate international and defense researcher at Rand corporation, Russia has long been building up an ecosystem of alternative social media platforms. But people tend to be more skeptical and cautious when using them out of fear that the government is involved in their operations and users' information isn't secure. "Either Russia has a hand in the building of the platform from this start, or they strong arm or co-opt whatever is popular later," Demus told Insider. "I know there's significant use of platforms like WhatsApp or others that are believed to be encrypted for that very reason — so that there can be open communication without the fear of reprisal." Russia has also enacted laws to exert influence on non-Russian social media platforms, including passing legislation stating companies need to place their servers for Russian accounts on Russian territory. "Presumably so they can then sort of meddle and do whatever kind of surveillance they need to," Demus said. Demus adds at one point that "anything Russia touches has the potential to land you in jail." But the article also notes that younger tech-savvy Russians are using VPNs to access sites blocked by the government — ultimately resulting in a kind of "generation gap" where they're less aligned with pro-government rhetoric from state-controlled media.

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"?

"Google is taking aim at Microsoft's dominance in government technology and security," reports NBC News: Jeanette Manfra, director of risk and compliance for Google's cloud services and a former top U.S. cybersecurity official, said Thursday that the government's reliance on Microsoft — one of Google's top business rivals — is an ongoing security threat. Manfra also said in a blog post published Thursday that a survey commissioned by Google found that a majority of federal employees believe that the government's reliance on Microsoft products is a cybersecurity vulnerability. "Overreliance on any single vendor is usually not a great idea," Manfra said in a phone interview. "You have an attack on one product that the majority of the government is depending on to do their job, you have a significant risk in how the government can continue to function." Microsoft pushed back strongly against the claim, calling it "unhelpful." The study comes as Google is positioning itself to challenge Microsoft's dominance in federal government offices, where Windows and Office programs are commonly used.... The blog post comes as hackers continue to discover critical software vulnerabilities at an increasing pace across major tech products, but especially in Microsoft programs. Last year, researchers discovered 21 "zero-days" — an industry term for a critical vulnerability that a company doesn't have a ready solution for — actively in use against Microsoft products, compared to 16 against Google and 12 against Apple. he most prominent zero-day was used against Microsoft's Exchange email program, which cybersecurity experts say was first employed by Chinese cyberspies and then quickly adopted by criminal hackers, leading to hundreds of companies becoming compromised.

The Paramount+ streaming service already has five ongoing Star Trek series (including Discovery and Picard). But they've just released a trailer for another one — and it's now derived directly from the original 1960s TV show, even including some of its original characters. The upcoming show's title? Star Trek: Strange New Worlds. Ars Technica reports: As we've reported previously, one of the highlights of Star Trek: Discovery's second season was the appearance of classic original series (TOS) characters Capt. Christopher Pike (Anson Mount), Number One (Rebecca Romijn), and Spock (Ethan Peck). All three reprise their roles for Strange New Worlds.... "If you want to seek out new life, go where the aliens are," Pike tells us. But that alien life might not be receptive to first contact, as Pike and the Enterprise find themselves under fire by aliens who consider their presence to be "blasphemy." And romance blooms for both Pike and Spock (separately, not with each other). Star Trek: Strange New Worlds debuts on Paramount+ on May 5, 2022. The streaming platform has already greenlighted a second season, with Paul Wesley (Vampire Diaries ) joining the cast as future Enterprise Capt. James T. Kirk. Ars Technica reports the cast as: Babs Olusanmokun playing Dr. M'BengaCelia Rose Gooding filling Nichelle Nichols' shoes as Cadet Nyota UhuraJess Bush playing Nurse Christine ChapelMelissa Navai playing Lt. Erica OrtegasBruce Orak playing an Aenar named Hemmer.Christina Chong playing La'An Noonien-Singh (a relation of the classic revenge-obsessed Star Trek villain Khan). And on an unrelated note...

Neowin notes growing support for the "very efficient, potent, royalty-free video codec" AV1, including Microsoft's adding of support for hardware acceleration of AV1 on Windows. But AV1 even turned up in Intel's announcement this week of the Arc A-series, a new line of discrete GPUs, Neowin reports: Intel has been quick to respond and the company has become the first such GPU hardware vendor to have full AV1 support on its newly launched Arc GPUs. While AMD and Nvidia both offer AV1 decoding with their newest GPUs, neither have support for AV1 encoding. Intel says that hardware encoding of AV1 on its new Arc GPUs is 50 times faster than those based on software-only solutions. It also adds that the efficiency of AV1 encode with Arc is 20% better compared to HEVC. With this feature, Intel hopes to potentially capture at least some of the streaming and video editing market that's based on users who are looking for a more robust AV1 encoding solution compared to CPU-based software approaches. From Intel's announcement: Intel Arc A-Series GPUs are the first in the industry to offer full AV1 hardware acceleration, including both encode and decode, delivering faster video encode and higher quality streaming while consuming the same internet bandwidth. We've worked with industry partners to ensure that AV1 support is available today in many of the most popular media applications, with broader adoption expected this year. The AV1 codec will be a game changer for the future of video encoding and streaming.

The BBC reported Friday that "Facebook users around the world have been waking up to find themselves locked out of their accounts for no apparent reason." The message many received reads: "Your Facebook account was disabled because it did not follow our Community Standards. This decision can't be reversed." [It appeared in a popup window with the title, "We Cannot Review the Decision to Disable Your Account."] One user told the BBC there was no warning or explanation given. While the message appeared on April 1st (April Fool's Day), the lockouts were real, confirmed on Twitter by Facebook's policy communications director Andy Stone. Later Friday he tweeted that "Earlier today, a technical issue caused a small number of people to have trouble accessing Facebook. We resolved the issue as quickly as possible for everyone who was impacted, and we apologize for any inconvenience." Numerous Twitter users then replied, complaining that their own accounts had been — and remained — disabled. "This happened to my father a couple of weeks ago and we are desperate to get his account back," one Twitter user told the Facebook communications official — while trying to explain the glitch's impact. "He has stage 4 cancer and uses the account to update his friends on his progress."

The C programming language has many problems. But now the Registers notes that "Aria Beingessner, a member of the teams that implemented both Rust and Swift, has an interesting take... That C isn't a programming language anymore...." "And it hasn't been for a long time," Beingessner writes in an online essay: This isn't about the fact that C is actually horribly ill-defined due to a billion implementations or its completely failed integer hierarchy. That stuff sucks, but on its own that wouldn't be my problem. My problem is that C was elevated to a role of prestige and power, its reign so absolute and eternal that it has completely distorted the way we speak to each other. Rust and Swift cannot simply speak their native and comfortable tongues — they must instead wrap themselves in a grotesque simulacra of C's skin and make their flesh undulate in the same ways it does.... Everyone had to learn to speak C to talk to the major operating systems, and then when it came time to talk to eachother we suddenly all already spoke C so... why not talk to eachother in terms of C too? Oops! Now C is the lingua franca of programming. Oops! Now C isn't just a programming language, it's a protocol. The Register picks up the argument: it's fair (if wildly controversial) to say, as this 2018 Association for Computing Machinery paper puts it, that C is not a low-level programming language. As its subtitle says: "Your computer is not a fast PDP-11." This is not a relative assessment: that is, it's not saying that there are other programming languages that are lower-level than C. It's an absolute one: C is often praised for being "close to the metal," for being a "portable assembly language." It was, once, but it hasn't been since the 1970s; the underlying computational models of modern computers are nothing like the one that C represents, which was designed for a 1970s 16-bit minicomputer. The Register summarizes what happens when a language has to interface with an operating system — and thus, that operating system's C code. [I]t has to call C APIs. This is done via Foreign Function Interfaces (FFIs).... In other words, even if you never write any code in C, you have to handle C variables, match C data structures and layouts, link to C functions by name with their symbols.... The real problem is that C was never designed or intended to be an Interface Definition Language, and it isn't very good at it.

"For 50 years, interplanetary probes have returned thousands of striking images of the surface of Mars, but never a single sound." So says the largest fundamental science agency in Europe, the French National Centre for Scientific Research (France's state research organisation). Then they made a surprising discovery, reports CBS News: Researchers studying recordings made by microphones on NASA's Perseverance rover found that sound travels much slower on Mars than it does on Earth... In addition, the researchers realized that there are two speeds of sound on Mars — one for high-pitched sounds and one for low-pitched sounds. This would "make it difficult for two people standing only five meters apart to have a conversation," according to a press release on the findings. The unique sound environment is due to the incredibly low atmospheric surface pressure. Mars' pressure is 170 times lower than Earth's pressure. For example, if a high-pitched sound travels 213 feet on Earth, it will travel just 26 feet on Mars. While sounds on Mars can be heard by human ears, they are incredibly soft. "At some point, we thought the microphone was broken, it was so quiet," said Sylvestre Maurice, an astrophysicist at the University of Toulouse in France and lead author of the study, according to NASA. Besides the wind, "natural sound sources are rare," the press release said. But NASA scientists think Mars may become more noisy in the autumn months, when there is higher atmospheric pressure. "We are entering a high-pressure season," co-author of the study Baptiste Chide said in the press release. "Maybe the acoustic environment on Mars will be less quiet than it was when we landed."

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.

The Seattle Times surveys the landscape after a historic unionization vote at an Amazon warehouse in New York — and finds the same sentiments are spurring activism by workers three timezones away: As the world watched thousands of Amazon warehouse workers in New York form on Friday the company's first U.S. union, a handful of employees of a Seattle thrift store celebrated their own victory. Sixteen workers at Crossroads Trading Co. in search of higher wages, more hours and better benefits voted unanimously Wednesday to form a union at the chain's store in Seattle's Capitol Hill neighborhood. Organizers at Crossroads said they built off the momentum and union support in the neighborhood from another successful union drive at a Starbucks store just a few blocks away. Now, a group of security workers who have contracts with Amazon, Microsoft and Sound Transit are taking a similar tack, hoping to use the swell of enthusiasm created by Amazon workers in Staten Island to bring more workers in Seattle into the union fold.... Since Amazon Labor Union started organizing — unofficially with a walkout in 2020 in protest of the company's treatment of workers amid the COVID-19 pandemic — the union wave appears to have swelled in the Seattle area. A group of workers at an Amazon Fresh store in Seattle's Central District organized to form Amazon Workers United, and now three more stores in the area are starting their own drives, according to organizer Joseph Fink. Workers at Verizon retail stores in Everett and Lynnwood are currently casting votes in a union election. Ballots were sent to workers in March and votes will be counted this month. In Seattle, a Starbucks retail store on Capitol Hill became the first unionized store in the region.... Watching workers at companies including Starbucks and Amazon face anti-union tactics did stoke fears of retaliation for union efforts at Crossroads, said Emma Mudd, a sales associate and one of the lead union organizers. But it exposed the playbook that companies might follow — and showed what workers could do to push back, engage one another and put public pressure on the company. "It was helpful to have tangible examples, because we did have conversations to prepare for union busting," Mudd said. "It was really helpful to see how those workers were able to push through it."
