For anyone looking to get a great deal on a streaming device, Roku’s Black Friday deals are here. The Roku Streaming Stick Plus, which just happens to be one of our favorite streaming devices, is 50 percent off, on sale for just $20. The regular Streaming Stick and Streaming Stick 4K are also on sale for 47 percent and 50 percent off, coming in at $16 and $25 respectively.

Roku makes some of the best streaming devices you can get, and any of the ones on sale would be great picks to upgrade an old TV you already have. The Streaming Stick Plus is our favorite of the bunch since it supports 4K HDR content and gives you access to a bunch of free content thanks to Roku’s streaming OS. We also appreciate its accurate universal search and the fact that it draws power from your TV, so it doesn’t need to be plugged into a wall outlet to get power.

The standard Streaming Stick is a good alternative to Amazon’s most basic Fire TV Stick, and if you already prefer Roku’s streaming OS, it’s arguably the better choice. The Streaming Stick 4K adds Dolby Vision into the mix, if that’s a must-have for you. Also, if you’re looking for a more powerful set-top streaming box, the Roku Ultra is 30 percent off, marked down to $70 from $100.

Our pick for the best robot vacuum (or at least one of its many variants) is on sale. Amazon’s Black Friday deals include the Shark AI Ultra robot vacuum. This model has a list price of $599, but you can snag one for $250. That’s 58 percent off — and a record low.

One of this model’s standout features is its bagless design. Like many robovacs, it has an auto-empty station. But here, you can remove part of the base, dump its contents in the garbage, and lock it back in place. The base holds up to 60 days of dirt and debris, and you’ll never need to order bag refills.

The Shark AI Ultra has strong suction and decent obstacle avoidance (via LiDAR). The robovac cleans in a matrix grid. It auto-maps your home and supports Google Assistant and Alexa for voice control.

The vacuum has a runtime of about 120 minutes. (If it needs to stop and charge, it will auto-resume afterward.) Also note that this is a vacuum-only model: no mopping here.

Canadian librarian Ian Linkletter has ended a five-year legal battle with ed-tech firm Proctorio after being sued for sharing public YouTube help videos that exposed how the company’s remote-proctoring AI works. Ars Technica reports: … Together, the videos, the help center screenshot, and another screenshot showing course material describing how Proctorio works were enough for Proctorio to take Linkletter to court. The ed tech company promptly filed a lawsuit and obtained a temporary injunction by spuriously claiming that Linkletter shared private YouTube videos containing confidential information. Because the YouTube videos — which were public but “unlisted” when Linkletter shared them — had been removed, Linkletter did not have to delete the seven tweets that initially caught Proctorio’s attention, but the injunction required that he remove two tweets, including the screenshots.

In the five years since, the legal fight dragged on, with no end in sight until last week, as Canadian courts tangled with copyright allegations that tested a recently passed law intended to shield Canadian rights to free expression, the Protection of Public Participation Act. To fund his defense, Linkletter said in a blog announcing the settlement that he invested his life savings “ten times over.” Additionally, about 900 GoFundMe supporters and thousands of members of the Association of Administrative and Professional Staff at UBC contributed tens of thousands more. For the last year of the battle, a law firm, Norton Rose Fulbright, agreed to represent him on a pro bono basis, which Linkletter said âoewas a huge relief to me, as it meant I could defend myself all the way if Proctorio chose to proceed with the litigation.”

The terms of the settlement remain confidential, but both Linkletter and Proctorio confirmed that no money was exchanged. For Proctorio, the settlement made permanent the injunction that restricted Linkletter from posting the company’s help center or instructional materials. But it doesn’t stop Linkletter from remaining the company’s biggest critic, as “there are no other restrictions on my freedom of expression,” Linkletter’s blog noted. “I’ve won my life back!” Linkletter wrote, while reassuring his supporters that he’s “fine” with how things ended. “It doesn’t take much imagination to understand why Proctorio is a nightmare for students,” Linkletter wrote. “I can say everything that matters about Proctorio using public information.”

Researchers in Germany achieved a major milestone for the future quantum internet by successfully teleporting quantum information between photons generated by two different, physically separated quantum dots — something never accomplished before due to the difficulty of producing indistinguishable photons from remote sources. Phys.org reports: At the University of Stuttgart, the team succeeded in teleporting the polarization state of a photon originating from one quantum dot to another photon from a second quantum dot. One quantum dot generates a single photon, the other an entangled photon pair. Entangled means that the two particles constitute a single quantum entity, even when they are physically separated. One of the two particles travels to the second quantum dot and interferes with its light particle. The two overlap. Because of this superposition, the information of the single photon is transferred to the distant partner of the pair.

Instrumental for the success of the experiment were quantum frequency converters, which compensate for residual frequency differences between the photons. These converters were developed by a team led by Prof. Christoph Becher, an expert in quantum optics at Saarland University. […] In the Stuttgart experiment, the quantum dots were separated only by an optical fiber of about 10 m length. “But we are working on achieving considerably greater distances,” says Strobel. In earlier work, the team had shown that the entanglement of the quantum dot photons remains intact even after a 36-kilometer transmission through the city center of Stuttgart. Another aim is to increase the current success rate of teleportation, which currently stands at just over 70%. Fluctuations in the quantum dot still lead to slight differences in the photons. The findings have been published in the journal Nature Communications.

Not everyone appreciates the artistry of Jackson Pollock’s famous drip paintings, with some dismissing them as something any child could create. While Pollock’s work is undeniably more sophisticated than that, it turns out that when one looks at splatter paintings made by adults and young children through a fractal lens and compares them to those of Pollock himself, the children’s work does bear a closer resemblance to Pollock’s than those of the adults. This might be due to the artist’s physiology, namely a certain clumsiness with regard to balance, according to a new paper published in the journal Frontiers in Physics.

Co-author Richard Taylor, a physicist at the University of Oregon, first found evidence of fractal patterns in Pollock’s seemingly random drip patterns in 2001. As previously reported, his original hypothesis drew considerable controversy, both from art historians and a few fellow physicists. In a 2006 paper published in Nature, Case University physicists Katherine Jones-Smith and Harsh Mathur claimed Taylor’s work was “seriously flawed” and “lacked the range of scales needed to be considered fractal.” (To prove the point, Jones-Smith created her own version of a fractal painting using Taylor’s criteria in about five minutes with Photoshop.)

Taylor was particularly criticized for his attempt to use fractal analysis as the basis for an authentication tool to distinguish genuine Pollocks from reproductions or forgeries. He concedes that much of that criticism was valid at the time. But as vindication, he points to a machine learning-based study in 2015 relying on fractal dimension and other factors that achieved a 93 percent accuracy rate distinguishing between genuine Pollocks and non-Pollocks. Taylor built on that work for a 2024 paper reporting 99 percent accuracy.

An anonymous reader quotes a report from the New York Times: When Mark Zuckerberg, Meta’s chief executive, unveiled the company’s Superintelligence Lab in June, he named 11 artificial intelligence researchers who were joining his ambitious effort to build a machine more powerful than the human brain. All 11 were immigrants educated in other countries. Seven were born in China, according to a memo viewed by The New York Times. Although many American executives, government officials and pundits have spent months painting China as the enemy of America’s rapid push into A.I., much of the groundbreaking research emerging from the United States is driven by Chinese talent.

Two new studies show that researchers born and educated in China have for years played major roles inside leading U.S. artificial intelligence labs. They also continue to drive important A.I. research in industry and academia, despite the Trump administration’s crackdown on immigration and growing anti-China sentiment in Silicon Valley. The research, from two organizations, provides a detailed look at how much the American tech industry continues to rely on engineers from China, particularly in A.I. The findings also offer a more nuanced understanding of how researchers in the two countries continue to collaborate, despite increasingly heated language from Washington and Beijing.

Longtime Slashdot reader ukoda shares a report from the Associated Press: China is replacing its diesel trucks with electric models faster than expected, potentially reshaping global fuel demand and the future of heavy transport. In 2020, nearly all new trucks in China ran on diesel. By the first half of 2025, battery-powered trucks accounted for 22% of new heavy truck sales, up from 9.2% in the same period in 2024, according to Commercial Vehicle World, a Beijing-based trucking data provider. The British research firm BMI forecasts electric trucks will reach nearly 46% of new sales this year and 60% next year.

China’s trucking fleet, the world’s second-largest after the U.S., still mainly runs on diesel, but the landscape is shifting. Transport fuel demand is plateauing, according to the International Energy Agency and diesel use in China could decline faster than many expect, said Christopher Doleman, an analyst at the Institute for Energy Economics and Financial Analysis. Electric trucks now outsell LNG models in China, so its demand for fossil fuels could fall, and “in other countries, it might never take off,” he said. […]

The share of electrics in new truck sales, from 8% in 2024 to 28% by August 2025, has more than tripled as prices have fallen. Electric trucks outsold LNG-powered vehicles in China for five consecutive months this year, according to Commercial Vehicle World. While electric trucks are two to three times more expensive than diesel ones and cost roughly 18% more than LNG trucks, their higher energy efficiency and lower costs can save owners an estimated 10% to 26% over the vehicle’s lifetime, according to research by Chinese scientists. “When it comes to heavy trucks, the fleet owners in China are very bottom-line driven,” Doleman said.

A Tokyo court ruled that Cloudflare is liable for aiding manga piracy after failing to act on infringement notices and continuing to cache and serve content for major piracy sites, awarding about $3.2 million in damages. TorrentFreak says the decision sets a significant precedent in Japan, suggesting CDN providers can face direct liability when they don’t verify customers or respond adequately to large-scale copyright abuse. From the report: After a wait of more than three and a half years, the Tokyo District Court rendered its decision this morning. In a statement provided to TorrentFreak by the publishers, they declare “Victory Against Cloudflare” after the Court determined that Cloudflare is indeed liable for the pirate sites’ activities. In a statement provided to TorrentFreak, the publishers explain that they alerted Cloudflare to the massive scale of the infringement, involving over 4,000 works and 300 million monthly visits, but their requests to stop distribution were ignored.

“We requested that the company take measures such as stopping the distribution of pirated content from servers under its management. However, Cloudflare continued to provide services to the manga piracy sites even after receiving notices from the plaintiffs,” the group says. The publishers add that Cloudflare continued to provide services even after receiving information disclosure orders from U.S. courts, leaving them with “no choice but to file this lawsuit.”

“The judgment recognized that Cloudflare’s failure to take timely and appropriate action despite receiving infringement notices from the plaintiffs, and its negligent continuation of pirated content distribution, constituted aiding and abetting copyright infringement, and that Cloudflare bears liability for damages to the plaintiffs,” they write. “The judgment, in that regard, attached importance to the fact that Cloudflare, without conducting any identity verification procedures, had enabled a massive manga piracy site to operate “under circumstances where strong anonymity was secured,’ as a basis for recognizing the company’s liability.”

The publishers believe that the judgment clarifies the conditions under which a company such as Cloudflare incurs liability for copyright infringement. Failure to carry out identity verification appears at the top of the publishers’ list, followed by a lack of timely and appropriate action in response to infringement notices sent by rightsholders. “We believe this is an important decision given the current situation where piracy site operators often hide their identities and repeatedly conduct large-scale distribution using CDN services from overseas. We hope that this judgment will be a step toward ensuring proper use of CDN services. We will continue our efforts to protect the rights of works, creators, and related parties, while aiming for further expansion of legitimate content,” the publishers conclude. Cloudflare plans to appeal the verdict.

Adobe is buying Semrush for $1.9 billion in a move to supercharge its AI-driven marketing stack. Reuters reports: Semrush designs and develops AI software that helps companies with search engine optimization, social media and digital advertising. The acquisition, expected to close in the first half of next year, would allow Adobe to help marketers better understand how their brands are viewed by online consumers through searches on websites and generative AI bots such as ChatGPT and Gemini. “The price is steep as Semrush isn’t a massive revenue engine on its own, so Adobe is likely paying for strategic value. The payoff could be high too if Adobe can quickly turn Semrush’s data into monetizable AI products,” said Emarketer analyst Grace Harmon.

“While we are positive on Adobe restarting its M&A engine given the success that it has seen with this motion over the years… this deal likely does little to answer the questions revolving around the company’s creative cloud business,” added William Blair analysts.
