Torvalds Celebrates Git's 20th Anniversay. Is It More Famous Than Linux?

Celebrating Git's 20th anniversary, GitHub hosted a Q&A with Linus Torvalds, writes Its FOSS News. Among the other revelations: He says his college-age daughter sent a texting saying he's better known at her CS lab for Git than for Linux, "because they actually use Git for everything there." Which he describes as "ridiculous" because he maintained it for just four months before handing it off to Junio Hamano who's been heading up development for more than 19 years now. "When it did what I needed," Torvalds says, "I lost interest." Linus then goes on to share how Git was never a big thing for him, but a means to an end that prevented the Linux kernel from descending into chaos over the absence of a version control system. You see, before Git, Linux used BitKeeper for version control, but its proprietary licensing didn't sit too well with other Linux contributors, and Linus Torvalds had to look for alternatives. As it turned out, existing tools like CVS and Subversion were too slow for the job at hand, prompting him to build a new tool from scratch, with the coding part just taking 10 days for an early self-hostable version of Git. In its initial days, there were some teething issues, where users would complain about Git to Linus, even finding it too difficult to use, but things got calmer as the tool developed further. Torvalds thinks some early adopters had trouble because they were coming from a background that was more like CVS. "The Git mindset, I came at it from a file system person's standpoint, where I had this disdain and almost hatred of most source control management projects, so I was not at all interested in maintaining the status quo."

FSF Urges US Government to Adopt Free-as-in-Freedom Tax Filing Software

"A modern free society has an obligation to offer electronic tax filing that respects user freedom," says a Free Software Foundation blog post, "and the United States is not excluded from this responsibility." "Governments, and/or the companies that they partner with, are responsible for providing free as in freedom software for necessary operations, and tax filing is no exception." For many years now, a large portion of [U.S.] taxpayers have filed their taxes electronically through proprietary programs like TurboTax. Millions of taxpayers are led to believe that they have no other option than to use nonfree software or Service as a Software Substitute (SaaSS), giving up their freedom as well as their most private financial information to a third-party company, in order to file their taxes... While the options for taxpayers have improved slightly with the IRS's implementation of the IRS Direct File program [in 25 states], this program unfortunately does require users to hand over their freedom when filing taxes.... Taxpayers shouldn't have to use a program that violates their individual freedoms to file legally required taxes. While Direct File is a step in the right direction as the program isn't in the hands of a third-party entity, it is still nonfree software. Because Direct File is a US government-operated program, and ongoing in the process of being deployed to twenty-five states, it's not too late to call on the IRS to make Direct File free software. In the meantime, if you need to file US taxes and are yet to file, we suggest filing your taxes in a way that respects your user freedom as much as possible, such as through mailing tax forms. Like with other government interactions that snatch away user freedom, choose the path that most respects your freedom. Free-as-in-freedom software would decrease the chance of user lock-in, the FSF points out. But they list several other advantages, including: Repairability: With free software, there is no uncertain wait period or reliance on a proprietary provider to make any needed bug or security fixes. Transparency: Unless you can check what a program really does (or ask someone in the free software community to check for you), there is no way to know that the program isn't doing things you don't consent to it doing. Cybersecurity: While free software isn't inherently more secure than nonfree software, it does have a tendency to be more secure because many developers can continuously improve the program and search for errors that can be exploited. With proprietary programs like TurboTax, taxpayers and the U.S. government are dependent on TurboTax to protect the sensitive financial and personal information of millions with few (if any) outside checks and balances... Taxpayer dollars spent should actually benefit the taxpayers: Taxpayer dollars should not be used to fund third-party programs that seek to control users and force them to use their programs through lobbying.... "We don't have to accept this unjust reality: we can work for a better future, together," the blog post concludes (offering a "sample message" U.S. taxpayers could send to IRS Commissioner Danny Werfel). "Take action today and help make electronic tax filing free as in freedom for everyone."

WSJ Says China 'Acknowledged Its Role in U.S. Infrastructure Hacks'

Here's an update from the Wall Street Journal about a "widespread series of alarming cyberattacks on U.S. infrastructure." China was behind it, "Chinese officials acknowledged in a secret December meeting... according to people familiar with the matter..." The Chinese delegation linked years of intrusions into computer networks at U.S. ports, water utilities, airports and other targets, to increasing U.S. policy support for Taiwan, the people, who declined to be named, said... U.S. officials went public last year with unusually dire warnings about the uncovered Volt Typhoon effort. They publicly attributed it to Beijing trying to get a foothold in U.S. computer networks so its army could quickly detonate damaging cyberattacks during a future conflict. [American officials at the meeting perceived the remarks as "intended to scare the U.S. from involving itself if a conflict erupts in the Taiwan Strait."] The Chinese official's remarks at the December meeting were indirect and somewhat ambiguous, but most of the American delegation in the room interpreted it as a tacit admission and a warning to the U.S. about Taiwan, a former U.S. official familiar with the meeting said... In a statement, the State Department didn't comment on the meeting but said the U.S. had made clear to Beijing it will "take actions in response to Chinese malicious cyber activity," describing the hacking as "some of the gravest and most persistent threats to U.S. national security...." A Chinese official would likely only acknowledge the intrusions even in a private setting if instructed to do so by the top levels of Xi's government, said Dakota Cary, a China expert at the cybersecurity firm SentinelOne. The tacit admission is significant, he said, because it may reflect a view in Beijing that the likeliest military conflict with the U.S. would be over Taiwan and that a more direct signal about the stakes of involvement needed to be sent to the Trump administration. "China wants U.S. officials to know that, yes, they do have this capability, and they are willing to use it," Cary said. The article notes that top U.S. officials have said America's Defense Department "will pursue more offensive cyber strikes against China." But it adds that the administration "also plans to dismiss hundreds of cybersecurity workers in sweeping job cuts and last week fired the director of the National Security Agency and his deputy, fanning concerns from some intelligence officials and lawmakers that the government would be weakened in defending against the attacks."

Original 1977 'Star Wars' Cut Will Be Shown at a Theater for First Time in Decades

Long-time Slashdot reader sandbagger brings news that in June "a rare screening of the original 1977 Star Wars movie — complete with Han shooting first — will be shown at a theater in London..." Petapixel reports: Subsequent alterations made to the film are well-documented: Han Solo being shot at by the bounty hunter Greedo first, rather than the original in which anti-hero Han killed Greedo without being shot at. Then there is the addition of a CGI Jabba the Hutt who was only mentioned by name in the 1977 release. Fans have also complained about the color grading painted on re-releases. But for those attending the British Film Institute (BFI)'s Film on Film festival in London, they are in for a treat. Star Wars will play not once but twice on the opening night on June 12... BFI says the print is "unfaded" and "ready to transport us to a long time ago, and a galaxy far, far away, back to the moment in 1977 when George Lucas's vision cast a spell on cinema audiences." Lucas has little sympathy for those who want to see his first version of the film, telling the Associated Press in 2004, "I'm sorry you saw half a completed film and fell in love with it. But I want it to be the way I want it to be." The film festival promises "a glorious dye-transfer" of Star Wars — and will also show "a pristine 35mm print of the original US pilot episode of Twin Peaks, screening for the first time ever in the UK" — followed by a Q&A with the 1990 show's original star Kyle MacLachlan. On display to coincide with the opening night screening there is also a rare opportunity to view material from the original continuity script for Star Wars, which includes rare on-set Polaroids, annotations and deleted scenes. The script is from the collection of Ann Skinner, script editor on the original film, and is now cared for by the BFI National Archive.

Chrome To Patch Decades-Old 'Browser History Sniffing' Flaw That Let Sites Peek At Your History

Slashdot reader king*jojo shared this article from The Register: A 23-year-old side-channel attack for spying on people's web browsing histories will get shut down in the forthcoming Chrome 136, released last Thursday to the Chrome beta channel. At least that's the hope. The privacy attack, referred to as browser history sniffing, involves reading the color values of web links on a page to see if the linked pages have been visited previously... Web publishers and third parties capable of running scripts, have used this technique to present links on a web page to a visitor and then check how the visitor's browser set the color for those links on the rendered web page... The attack was mitigated about 15 years ago, though not effectively. Other ways to check link color information beyond the getComputedStyle method were developed... Chrome 136, due to see stable channel release on April 23, 2025, "is the first major browser to render these attacks obsolete," explained Kyra Seevers, Google software engineer in a blog post. This is something of a turnabout for the Chrome team, which twice marked Chromium bug reports for the issue as "won't fix." David Baron, presently a Google software engineer who worked for Mozilla at the time, filed a Firefox bug report about the issue back on May 28, 2002... On March 9, 2010, Baron published a blog post outlining the issue and proposing some mitigations...

America's Justice Department Shuts Down Its Cryptocurrency Fraud Unit

America's Justice Department "has shut down its unit that investigates cryptocurrency fraud," reports USA Today. A Monday night memo from U.S. Deputy Attorney General Todd Blanche said the shut down was "effective immediately." Blanche directed the closure of the National Cryptocurrency Enforcement Team and ordered prosecutors to pivot to investigating transnational criminal organizations and terrorist groups that use crypto to engage in illicit transactions... In his four-page memo, Blanche said the new order was meant to bring the Justice Department in line with Trump's own Executive Order 14178, which decreed that clarity and certainty regarding enforcement policy "are essential to supporting a vibrant and inclusive digital economy and innovation in digital assets." Blanche, one of several Trump criminal defense lawyers at the top ranks of DOJ, said the president "has also made clear that '[w]e are going to end the regulatory weaponization against digital assets'..." Consistent with that narrowing of its cryptocurrency enforcement policy, the DOJ Market Integrity and Major Frauds Unit will also cease cryptocurrency enforcement to focus on other administration priorities, including immigration and procurement fraud, Blanche said. The Washington Post got this assessment from Yesha Yadav, a Vanderbilt University law professor who closely follows cryptocurrency and financial markets. "It's hard to underestimate the importance this task force has had ... in pursuing some really huge crypto hacks and cases." More from USA Today: Public corruption and transnational crime experts warned that shutting down the unit could divert critical resources from efforts to stop criminals and corrupt regimes from using cryptocurrency for illicit gain, even as Trump claims he wants to crack down on them. "Dangerous US adversaries rely on cryptocurrencies to launder money and evade sanctions," said Nate Sibley, an anti-corruption expert and director of the Kleptocracy Initiative at the conservative Hudson Institute think tank in Washington, D.C., in a post on X. "If this is accurate, hard to see how it squares with — for example-cracking down on cartel finances or maximum pressure sanctions on Iran...." Trump's so-called "memecoin" surged from less than $10 on the Saturday before his inauguration to as high as $74.59 before eventually giving up some of its gains. The token, branded $TRUMP, has been criticized by ethics experts as a conflict of interest for the president since the company could likely benefit from his pro-crypto policies... Last month, Trump signed an order to create a federal Strategic Bitcoin Reserve, signaling new federal support for cryptocurrency in general and Bitcoin in particular. Since the first-ever White House crypto summit in March, America's Securities and Exchange Commission "has dropped more than a dozen cases against crypto firms," notes the Washington Post: Last month, both the Federal Deposit Insurance Corp. and the Office of the Comptroller of the Currency pledged to stop evaluating banks based on "reputational risk" — a practice that some venture capitalists have claimed unfairly "de-banked" founders of cryptocurrency start-ups. In other news, executives from cryptocurrency exchange Binance "met with Treasury Department officials last month," reports the Wall Street Journal, asking them to remove a U.S. monitor overseeing their compliance with anti-money-laundering laws, according to people familiar with the talks. The article adds that Binance is also concurrently "exploring" a deal with the Trump family to list its new dollar-pegged stablecoin which "could catapult it into a huge market and potentially bring in billions in profit for the family.

For the First Time Astronomers Watch a Black Hole 'Wake Up' in Real-Time

Black holes "often exhibit long periods of dormancy," writes Popular Science, adding that astronomers had never witnessed a black hole "wake up" in real time. "Until now..." In February of 2024 X-ray bursts were spotted coming out of a black hole named Ansky by Lorena Hernández-García at Chile's Valparaiso University, according to the article. And what astronomers have now seen "challenges prevailing theories about black hole lifecycles." Hernández-García and collaborators then determined the black hole was displaying a phenomenon known as a quasiperiodic eruption, or QPE [a short-lived flaring event...] While a black hole inevitably destroys everything it captures, objects behave differently during their impending demise. A star, for example, generally stretches apart into a bright, hot, fast-spinning disc known as an accretion disc. Most astronomers have theorized that black holes generate QPEs when a comparatively small object like a star or even a smaller black hole collides with an accretion disc. In the case of Ansky, however, there isn't any evidence linking it to the death of a star. "The bursts of X-rays from Ansky are ten times longer and ten times more luminous than what we see from a typical QPE," said MIT PhD student and study co-author Joheen Chakraborty. "Each of these eruptions is releasing a hundred times more energy than we have seen elsewhere. Ansky's eruptions also show the longest cadence ever observed, of about 4.5 days." Astronomers must now consider other explanations for Ansky's remarkable behavior. One theory posits that the accretion disc could come from nearby galactic gas pulled in by the black hole instead of a star. If true, then the X-rays may originate from high energy shocks to the disc caused by a small cosmic object repeatedly passing through and disrupting orbital matter. It's detailed in a study published on April 11 in Nature Astronomy.... Meanwhile, scientists "have uncovered the strongest evidence yet for the existence of elusive intermediate-mass black holes," reports SciTechDaily. And there's more black hole news from RockDoctor (Slashdot reader #15,477): Given the recent work on galaxy-centre Super-Massive Black Holes (SMBHs), you may be surprised to learn that the only Stellar-Mass Black Holes (SMBHs ... uh, "BHs") identified to-date have been by their gravitational waves, as they merge with another BH or a neutron star. But the long-running OGLE (Optical Gravitational Lensing Experiment) project (1992 — present) has recently confirmed that it has detected an isolated BH not orbiting another bright object, or "swallowing" much of anything... In this case, 16 other telescopes performed sensitive astrometry (position measurement) over 11 years including the Hubble Space Telescope (HST). These multiple measurements plot an ellipse on the sky, mirroring the movement of the Earth around it's orbit — parallax. Which means this is a relatively close object (1520 parsecs / ~5000 light years).... And there is no sign of a third light emitting body nearby, which means this is an isolated black hole, not orbiting any other body (or, indeed, with any other [small] star orbiting it).

Germany's 'Universal Basic Income' Experiment Proves It Doesn't Encourage Unmployment

People "are likely to continue working full-time even if they receive no-strings-attached universal basic income payments," reports CNN, citing results from a recent experiment in Germany (discussed on Slashdot in 2020): Mein Grundeinkommen (My Basic Income), the Berlin-based non-profit that ran the German study, followed 122 people for three years. From June 2021 to May 2024, this group received an unconditional sum of €1,200 ($1,365) per month. The study focused on people aged between 21 and 40 who lived alone and already earned between 1,100 euros (around $1,250) and 2,600 euros ($2,950) a month. They were free to use the extra money from the study on anything they wanted. Over the course of three years, the only condition was that they had to fill out a questionnaire every six months that asked about different areas of their lives, including their financial situation, work patterns, mental well-being and social engagement. One concern voiced by critics is that receiving a basic income could make people less inclined to work. But the Grundeinkommen study suggests that may not be the case at all. It found that receiving a basic income was not a reason for people to quit their jobs. On average, study participants worked 40 hours a week and stayed in employment — identical to the study's control group, which received no payment. "We find no evidence that people love doing nothing," Susann Fiedler, a professor at the Vienna University of Economics and Business who was involved with the study, said on the study's website. Unlike the control group, those receiving a basic income were more likely to change jobs or enroll in further education. They reported greater satisfaction in their working life — and were "significantly" more satisfied with their income... And can more money buy happiness? According to the study, the recipients of a basic income reported feeling that their lives were "more valuable and meaningful" and felt a clear improvement in their mental health.

AI Industry Tells US Congress: 'We Need Energy'

The Washington Post reports: The United States urgently needs more energy to fuel an artificial intelligence race with China that the country can't afford to lose, industry leaders told lawmakers at a House hearing on Wednesday. "We need energy in all forms," said Eric Schmidt, former CEO of Google, who now leads the Special Competitive Studies Project, a think tank focused on technology and security. "Renewable, nonrenewable, whatever. It needs to be there, and it needs to be there quickly." It was a nearly unanimous sentiment at the four-hour-plus hearing of the House Energy and Commerce Committee, which revealed bipartisan support for ramping up U.S. energy production to meet skyrocketing demand for energy-thirsty AI data centers. The hearing showed how the country's AI policy priorities have changed under President Donald Trump. President Joe Biden's wide-ranging 2023 executive order on AI had sought to balance the technology's potential rewards with the risks it poses to workers, civil rights and national security. Trump rescinded that order within days of taking office, saying its "onerous" requirements would "threaten American technological leadership...." [Data center power consumption] is already straining power grids, as residential consumers compete with data centers that can use as much electricity as an entire city. And those energy demands are projected to grow dramatically in the coming years... [Former Google CEO Eric] Schmidt, whom the committee's Republicans called as a witness on Wednesday, told [committee chairman Brett] Guthrie that winning the AI race is too important to let environmental considerations get in the way... Once the United States beats China to develop superintelligence, Schmidt said, AI will solve the climate crisis. And if it doesn't, he went on, China will become the world's sole superpower. (Schmidt's view that AI will become superintelligent within a decade is controversial among experts, some of whom predict the technology will remain limited by fundamental shortcomings in its ability to plan and reason.) The industry's wish list also included "light touch" federal regulation, high-skill immigration and continued subsidies for chip development. Alexandr Wang, the young billionaire CEO of San Francisco-based Scale AI, said a growing patchwork of state privacy laws is hampering AI companies' access to the data needed to train their models. He called for a federal privacy law that would preempt state regulations and prioritize innovation. Some committee Democrats argued that cuts to scientific research and renewable energy will actually hamper America's AI competitiveness, according to the article. " But few questioned the premise that the U.S. is locked in an existential struggle with China for AI supremacy. "That stark outlook has nearly coalesced into a consensus on Capitol Hill since China's DeepSeek chatbot stunned the AI industry with its reasoning skills earlier this year."

Microsoft is Killing Skype - and Refusing Refunds for Prepaid International Calls

Skype is shutting down after two decades on May 5th, notes the Washington Post. But the bigger problem for retired attorney Karen Griffin is that Microsoft won't refund the money they paid into a Skype account for cheap international phone calls: "They're no longer offering this service that I prepaid for, and now they're not giving me my money back," Griffin said. "There's a lot of people out there who are going to lose money...." To its credit, Microsoft gave Skype users a couple months' warning about the shutdown coming May 5. People can transfer Skype contacts and chat history to the company's Microsoft Teams chat-and-calling app or to other companies' services. (While Microsoft sells Teams to organizations, there's a free version for personal use.) But Microsoft didn't explain well what will happen to money that people like Griffin have parked in Skype accounts, in some cases for years.... Unless you bought Skype credits very recently, Microsoft said it won't refund money in Skype accounts. The company says it will add an option for Skype account holders to keep using their funds for phone calls online or in Teams. Griffin doesn't love what Microsoft is doing. She prefers a cash refund or a credit applied to her Microsoft Office subscription, for which she pays about $110 a year. Amit Fulay, vice president of product for Skype and Teams, said it's not possible to shift funds from a Skype account to Office subscriptions. And he nixed refunds because Microsoft will still offer basic call services for former Skype customers. "Refunds make more sense if you took away something," Fulay said. "We're not." Microsoft declined to say how much money Skype users collectively have sitting in accounts that they might never use. Stacey Higginbotham, a policy specialist with Consumer Reports' technology advocacy team, said Griffin is making a reasonable request for a rich company like Microsoft that's shutting down an internet service. "The best way: Give people their money back. The second-best way, give people a credit to all of your services," Higginbotham said.

Trump Tariffs Add Exemptions Friday Night for Smartphones and Other Electronics

Smartphones, computer monitors, semiconductors, and various other electronics will be exempt from U.S. President Trump's tariffs, reports CNN, "according to a US Customs and Border Protection notice posted late Friday." And several other products also received an exemption which "applies to products entering the United States or removed from warehouses as early as April 5, according to the notice." Roughly 90% of Apple's iPhone production and assembly is based in China, according to Wedbush Securities' estimates. Counterpoint Research, a firm that monitors global smartphone shipments, estimated Apple has up to six weeks of inventory in the United States. Once that supply runs out, prices would have been expected to go up... Semiconductors and microchips are among the products heavily outsourced to factories in Asia due to lower costs. Those electronic parts are now exempt, according to the Friday notice. That could help Asian chipmakers, such as Taiwan Semiconductor Manufacturing Company (TSMC), South Korea's Samsung and SK Hynix. The exemptions also include solar cells, memory cards, and computers, according to the BBC. "It was not clear whether technology imports from China would still be hit by a 20% tariff that was not part of the reciprocal tariffs announced on 2 April..." Thanks to Slashdot readers Alain Williams and Mr. Dollar Ton for sharing the news.

Facebook Whistleblower Alleges Meta's AI Model Llama Was Used to Help DeepSeek

A former Facebook employee/whistleblower alleges Meta's AI model Lllama was used to help DeepSeek. The whistleblower — former Facebook director of global policy Sarah Wynn-Williams — testified before U.S. Senators on Wednesday. CBS News found this earlier response from Meta: In a statement last year on Llama, Meta spokesperson Andy Stone wrote, "The alleged role of a single and outdated version of an American open-source model is irrelevant when we know China is already investing over 1T to surpass the US technologically, and Chinese tech companies are releasing their own open AI models as fast, or faster, than US ones." Wynn-Williams encouraged senators to continue investigating Meta's role in the development of artificial intelligence in China, as they continue their probe into the social media company founded by Zuckerberg. "The greatest trick Mark Zuckerberg ever pulled was wrapping the American flag around himself and calling himself a patriot and saying he didn't offer services in China, while he spent the last decade building an $18 billion business there," she said. The testimony also left some of the lawmakers skeptical of Zuckerberg's commitment to free speech after the whistleblower also alleged Facebook worked "hand in glove" with the Chinese government to censor its platforms: In her almost seven years with the company, Wynn-Williams told the panel she witnessed the company provide "custom built censorship tools" for the Chinese Communist Party. She said a Chinese dissident living in the United States was removed from Facebook in 2017 after pressure from Chinese officials. Facebook said at the time it took action against the regime critic, Guo Wengui, for sharing someone else's personal information. Wynn-Williams described the use of a "virality counter" that flagged posts with over 10,000 views for review by a "chief editor," which Democratic Sen. Richard Blumenthal of Connecticut called "an Orwellian censor." These "virality counters" were used not only in Mainland China, but also in Hong Kong and Taiwan, according to Wynn-Williams's testimony. Wynn-Williams also told senators Chinese officials could "potentially access" the data of American users.

Leaving Money on the Table

Abstract of a paper on NBER: There is much disagreement about the extent to which financial incentives motivate study participants. We elicit preferences for being paid for completing a survey, including a one-in-twenty chance of winning a $100 electronic gift card, a guaranteed electronic gift card with the same expected value, and an option to refuse payment. More than twice as many participants chose the lottery as chose the guaranteed payment. Given that most people are risk averse, this pattern suggests that factors beyond risk preferences -- such as hassle costs -- influenced their decision-making. Almost 20 percent of participants actively refused payment, demonstrating low monetary motivation. We find both systematic and unobserved heterogeneity in the characteristics of who turned down payment. The propensity to refuse payment is more than four times as large among individuals 50 and older compared to younger individuals, suggesting a tradeoff between financially motivating participants and obtaining a representative sample. Overall, our results suggest that modest electronic gift card payments violate key requirements of Vernon Smith's induced value theory.

#Flock : la météo rit du complot

Ah mes chers amis, l’heure est-elle à la prise de température à l’aide d’un baromètre ? Celui des bourses est fébrile au moindre postillon, la fièvre orangeâtre se répand plus vite qu’un tweet. Les fouilles au corps ne servent à rien tant les personnes s’en sont mis plein. Le coup est gros comme une baleine, pas besoin d’IA pour le calculer de loin ou de près, et ce n’est pas le rêve d’avoir un iphone 100% US qui justifiera le move. Comme dirait tout bon politique qui ne respecte rien : plus c’est gros, plus ça passe. Sauf pour quelques-uns qui feraient mieux de se faire tout petits. Allez, bon weekend ! 🙂
