Microsoft has made some of its certification exams open book affairs, allowing access to its learning portal while candidates sit tests. From a report: "On August 22, we will begin updating our exams so that you will be able to access Microsoft Learn as you complete your exam," wrote Liberty Munson, director of psychometrics at Microsoft's Worldwide Learning organization. Microsoft Learn is a portal that links to product documentation, tutorials, code fragments, and other technical material.

Much of that content will be available during exams, although a technical Q&A service will remain hidden. The open book exams will be offered to candidates sitting exams for the role-based certifications Microsoft offers for job titles including Azure Administrator, Developer, Solutions Architect, DevOps Engineer; Microsoft 365 Modern Desktop Administrator, and Enterprise Administrator. Exams at Associate, Expert, and Specialty levels of competency will all offer access to the Learn portal. The material will become available for all role-based and specialty exams, in all languages, by mid-September 2023. Looking up material on Learn won't stop the clock during an exam, and the experience of taking the test will remain unchanged -- other than allowing candidates to open a window in which to view the educational portal.

Chess.com and Hans Niemann have reached a settlement in which Niemann has agreed to drop a $100 million lawsuit against Chess.com and Magnus Carlsen, and will be allowed to return to compete, the company announced Monday. From a report: This puts an end to the legal aspect of a cheating scandal that captivated the chess world for nearly a year. As part of the settlement, chess world champion Carlsen said "there is no determinative evidence that Niemann cheated in his game against me at the Sinquefield Cup. I am willing to play Niemann in future events, should we be paired together."

Helen Marie Plourde, an 86-year-old Minnesota resident, just spent over a month without home Internet and phone service because CenturyLink failed to fix a problem that began in July. From a report: CenturyLink didn't show up for scheduled appointments at her home in Saint Paul, Plourde told Ars in a phone interview on Thursday, August 24, one day after the latest missed service appointment. Another appointment was scheduled for August 28, but she was skeptical that it would actually happen. "I'll believe it when I see them," Plourde said. Plourde buys broadband through Velocity Telephone, which resells CenturyLink fiber service in her area and acts as an intermediary between customers and CenturyLink for repairs. Velocity told us that it set up CenturyLink appointments for Plourde on August 10, August 17, and August 23, but no CenturyLink technicians showed up to any of the appointments.

We talked to Plourde after hearing from Amalia Deloney, whose parents live nearby. Christopher Mitchell, director of the Community Broadband Networks Initiative with the Institute for Local Self-Reliance in Minneapolis, put Deloney in touch with us. "For the past month, [Plourde] has been going to my mom and dad's house to use the Internet two times a day because hers went out and CenturyLink can't be bothered fixing it. She's ready to write letters to elected officials and the Utilities Commission out of desperation," Deloney said. That didn't end up being necessary because CenturyLink sprang into action after Ars contacted the company's media relations team on Thursday night. A CenturyLink technician went to Plourde's home on Friday morning and fixed a line problem on a nearby street, restoring her Internet and VoIP phone service. Velocity, the CenturyLink reseller, also offers its own fiber service on infrastructure it owns in parts of Minnesota, but not where Plourde lives. Comcast is the other option at Plourde's house. She chose Velocity to support a local company.

In an enforcement action announced on Monday, the Securities and Exchange Commission charged Los Angelesâ"based entertainment company Impact Theory with conducting an unregistered offering of securities via non-fungible tokens, or NFTs. From a report: As the SEC expands its definition of which types of crypto assets qualify as securities, the case breaks new ground by determining that NFTs fall under the agency's jurisdiction. "Absent a valid exemption, offerings of securities, in whatever form, must be registered," Antonia Apps, director of the SEC's New York Regional Office, said in a statement.

The question of whether NFTs qualify as securities has remained open for several years. Before the SEC weighed in, a lawsuit in the U.S. District Court for the Southern District of New York remained the highest-profile case to tackle the issue, with a group of NFT collectors suing Dapper Labs. The plaintiffs alleged that the crypto firm had earned hundreds of millions of dollars by selling unregistered securities. Although Dapper Labs motioned for the case to be dismissed last year, a judge ruled in February that it could move forward, concluding that it was "plausible" NFTs could qualify as securities.

The Polish Railway's radio system was hacked on Friday and Saturday, bringing 20 freight and passenger trains to an unprecedented standstill. The hack, believed to be carried out by Russia, took advantage of a critical flaw in the railway's radio security system, with the issue reportedly restored within hours. From a report: An investigation into the cyberattack is underway, and the Polish Press Agency (PAP) reported that the radio signals sent to stop the trains were interspersed with a recording of Russia's national anthem and a speech by Russian President Vladimir Putin.

Poland is an important transportation hub that brings much-needed weapons supplied by Western countries and other aid to Ukraine amid the Russian invasion, and Senior Security Official Stanislaw Zaryn told PAP: "For the moment, we are ruling nothing out." He continued: "We know that for some months there have been attempts to destabilize the Polish state. Such attempts have been undertaken by the Russian Federation in conjunction with Belarus." Train services were reportedly restored within hours and the Polish State Railways said in a statement that "there is no threat to rail passengers" and the cyberattack only caused "difficulties in the running of trains."

The United States has enough geothermal energy to power the entire country. Some are trying to unlock it by using techniques from the fracking boom. From a report: Traditional geothermal plants, which have existed for decades, work by tapping natural hot water reservoirs underground to power turbines that can generate electricity 24 hours a day. Few sites have the right conditions for this, however, so geothermal only produces 0.4 percent of America's electricity currently. But hot, dry rocks lie below the surface everywhere on the planet. And by using advanced drilling techniques developed by the oil and gas industry, some experts think it's possible to tap that larger store of heat and create geothermal energy almost anywhere. The potential is enormous: The Energy Department estimates there's enough energy in those rocks to power the entire country five times over and has launched a major push to develop technologies to harvest that heat.

Dozens of geothermal companies have emerged with ideas. Fervo is using fracking techniques -- similar to those used for oil and gas -- to crack open dry, hot rock and inject water into the fractures, creating artificial geothermal reservoirs. Eavor, a Canadian start-up, is building large underground radiators with drilling methods pioneered in Alberta's oil sands. Others dream of using plasma or energy waves to drill even deeper and tap "superhot" temperatures that could cleanly power thousands of coal-fired power plants by substituting steam for coal. Still, obstacles to geothermal expansion loom. Investors are wary of the cost and risks of novel geothermal projects. Some worry about water use or earthquakes from drilling. Permitting is difficult. And geothermal gets less federal support than other technologies.

The number of titles on streaming services jumped 39% over the past two years to 2.35 million, according to a report released Monday by market researcher Nielsen. From a report: Add in traditional broadcast and cable channels and the number of individual viewing options climbed to 2.7 million. The figures reflect movies and shows available in the US, Canada, the UK, Mexico and Germany. Netflix and Disney+ are among 167 streaming providers, up from 118 two years ago. The average time it takes someone to find something to watch has risen to more than 10 minutes from a little over seven minutes in 2019, Nielsen said.

An advertising watchdog has recommended that YouTube TV, Google's growing pay-TV streaming service, drops an ad claim that the service is "$600 less than cable." The recommendation from the National Advertising Division (NAD) stems from a complaint lodged by Charter Communications. From a report: NAD, which used an expedited process for single-issue advertising cases in making this decision, found that YouTube TV's pricing claim, which identifies "comparable standalone cable" as the basis of comparison, doesn't hold up. NAD noted that the price calculation underlying the challenged claim includes the cost of two set-top boxes per household for "standalone cable" services," but argued that such a comparison isn't a good fit because operators such as Charter offer pay-TV streaming options that may not require a set-top box. In Charter's case, its Spectrum TV app, billed as a platform that can "stream outside the cable box," is compatible with iOS and Android mobile devices along with several retail streaming devices and/or integrated connected TVs from companies such as Apple, Roku, Google and Samsung. "In the context of the 'cable' comparison, NAD found the claim reasonably conveys the cost of YouTube TV is compared to all cable services," the organization explained.

U.S. Commerce Secretary Gina Raimondo opened talks with Chinese government officials on Monday, saying it is "profoundly important" for the world's two largest economies to have a stable economic relationship. From a report: Raimondo is looking to boost business ties as U.S. firms have reported increasing challenges with operating in China, while China has sharply criticized U.S. efforts to block its access to advanced semiconductors. Raimondo said the entire world expects the United States and China will have a stable economic relationship; the two countries share more than $700 billion in annual trade. "It's a complicated relationship. "It's a challenging relationship. We will of course disagree on certain issues," Raimondo said. "I think we can make progress if we are direct, open and practical."

Slash_Account_Dot writes: Hackers are able to grab a target's IP address, potentially revealing their general physical location, by simply sending a link over the Skype mobile app. The target does not need to click the link or otherwise interact with the hacker beyond opening the message, according to a security researcher who demonstrated the issue and successfully discovered my IP address by using it. Yossi, the independent security researcher who uncovered the vulnerability, reported the issue to Microsoft earlier this month, according to Yossi and a cache of emails and bug reports he shared with 404 Media. In those emails Microsoft said the issue does not require immediate servicing, and gave no indication that it plans to fix the security hole. Only after 404 Media contacted Microsoft for comment did the company say it would patch the issue in an upcoming update.

To meet climate goals, some European countries are asking farmers to reduce livestock, relocate or shut down -- and an angry backlash has begun reshaping the political landscape before national elections in the fall. The New York Times: This summer, scores of farmers descended on the European Parliament in Strasbourg, France, to protest against new E.U. rules aimed at restoring natural areas and cutting emissions that contribute to climate change. Farmers have protested in Belgium, Italy and Spain, too. The discontent has underscored a widening divide on a continent that is on the one hand committed to acting on climate change but on the other often deeply divided about how to do it and who should pay for it.

[...] For many farmers, the feelings run deep. The prominent role of agriculture was enshrined in the European Union's founding documents as a way of ensuring food security for a continent still traumatized by the deprivations of World War II. But it was also a nod to national identities and a way to protect competing farming interests in what would become a common market. To that end, from its outset, the bloc established a fund that, to this day, provides farmers with billions of euros in subsidies every year. Increasingly, however, those subsidies and the bloc's founding ideals are running up against a new ambition: to adapt to a world where climate change threatens traditional ways of life. Scientists are adamant: To fulfill the bloc's goal of reaching net zero emissions by 2050 and to reverse biodiversity losses, Europe has to transform the way it produces its food.

The upcoming release of GNOME 45 — expected September 20th — will bring new features to the Nautilus file manager (now in public beta testing). An anonymous reader shared this report from 9to5Linux: Nautilus in GNOME 45 already received a search performance boost, support for dropping images directly from web pages, an improved Grid View that now indicates starred files too, the ability to display bytes size as a tooltip for folder properties, and a more adaptive design for the sidebar. It also got an improved file opening experience while sandboxed (think Flatpak, Snap, etc.), a more consistent date and time format, a more simplistic definition of the Keyboard Shortcuts window, the ability to refocus the search bar using the Ctrl+F keyboard shortcut, and a better archiving experience.

But there's room for more new features as Nautilus now received new "Search Everywhere" buttons to expand the search scope and a modern full-height sidebar layout, along with refined sidebar sizing and folding threshold. This is what Nautilus looks like in GNOME 45.
The article includes some screenshots, adding that Nautilus "also received some performance improvements to more quickly generate multiple thumbnails, provide users with flickerless transition into and from search, and avoid DBus-activating other apps when it starts."

An anonymous reader shared this report from the New York Times: It is powered into flight by a rocket engine. It can fly a distance equal to the width of China. It has a stealthy design and is capable of carrying missiles that can hit enemy targets far beyond its visual range. But what really distinguishes the Air Force's pilotless XQ-58A Valkyrie experimental aircraft is that it is run by artificial intelligence, putting it at the forefront of efforts by the U.S. military to harness the capacities of an emerging technology whose vast potential benefits are tempered by deep concerns about how much autonomy to grant to a lethal weapon.

Essentially a next-generation drone, the Valkyrie is a prototype for what the Air Force hopes can become a potent supplement to its fleet of traditional fighter jets, giving human pilots a swarm of highly capable robot wingmen to deploy in battle. Its mission is to marry artificial intelligence and its sensors to identify and evaluate enemy threats and then, after getting human sign-off, to move in for the kill... The emergence of artificial intelligence is helping to spawn a new generation of Pentagon contractors who are seeking to undercut, or at least disrupt, the longstanding primacy of the handful of giant firms who supply the armed forces with planes, missiles, tanks and ships. The possibility of building fleets of smart but relatively inexpensive weapons that could be deployed in large numbers is allowing Pentagon officials to think in new ways about taking on enemy forces.

It also is forcing them to confront questions about what role humans should play in conflicts waged with software that is written to kill...
The article adds that the U.S. Air Force plans to build 1,000 to 2,000 AI drones for as little as $3 million apiece. "Some will focus on surveillance or resupply missions, others will fly in attack swarms and still others will serve as a 'loyal wingman' to a human pilot....

"A recently revised Pentagon policy on the use of artificial intelligence in weapons systems allows for the autonomous use of lethal force — but any particular plan to build or deploy such a weapon must first be reviewed and approved by a special military panel."
