  • Adobe Bolsters AI Marketing Tools With $1.9 Billion Semrush Buy
    by BeauHD on 20/11/2025 at 12:02 am

    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.

  • Apple N1 Wi-Fi Chip Improves On Older Broadcom Chips In Every Way
    by BeauHD on 19/11/2025 at 11:23 pm

    An anonymous reader quotes a report from Ars Technica: This year's newest iPhones included one momentous change that marked a new phase in the evolution of Apple Silicon: the Apple N1, Apple's first in-house chip made to handle local wireless connections. The N1 supports Wi-Fi 7, Bluetooth 6, and the Thread smart home communication protocol, and it replaces the third-party wireless chips (mostly made by Broadcom) that Apple used in older iPhones. Apple claimed that the N1 would enable more reliable connectivity for local communication features like AirPlay and AirDrop but didn't say anything about how users could expect it to perform. But Ookla, the folks behind the SpeedTest app and website, have analyzed about five weeks' worth of users' testing data to get an idea of how the iPhone 17 lineup stacks up to the iPhone 16, as well as Android phones with Wi-Fi chips from Qualcomm, MediaTek, and others. While the N1 isn't at the top of the charts, Ookla says Apple's Wi-Fi chip "delivered higher download and upload speeds on Wi-Fi compared to the iPhone 16 across every studied percentile and virtually every region." The median download speed for the iPhone 17 series was 329.56Mbps, compared to 236.46Mbps for the iPhone 16; the upload speed also jumped from 73.68Mbps to 103.26Mbps. Ookla noted that the N1's best performance seemed to improve scores most of all in the bottom 10th percentile of performance tests, "implying Apple's custom silicon lifts the floor more than the ceiling." The iPhone 17 also didn't top Ookla's global performance charts -- Ookla found that the Pixel 10 Pro series slightly edges out the iPhone 17 in download speed, while a Xiaomi 15T Pro with MediaTek Wi-Fi silicon featured better upload speeds.

  • Saudi Makes Big Bet On AI Films As Hollywood Moves From Studios To Datacenters
    by BeauHD on 19/11/2025 at 10:45 pm

    pbahra writes: Saudi Arabia is betting that the future of Hollywood won't be built in physical stages but in datacenters. In a push to anchor itself in next-generation film production, Riyadh-based Humain has led Luma AI's latest Series C round, backing the shift towards cloud-based, AI-generated video rather than traditional studio infrastructure.. Humain's announcement says the new investment will accelerate Luma's development of world models capable of learning from video, audio and language to generate photorealistic scenes, environments and characters on demand. Supporters argue this could upend film-making by pushing much of Hollywood's production pipeline into high-performance datacenters rather than physical sets. Read more of this story at Slashdot.

  • Nvidia Beats Earnings Expectations, Even As Bubble Concerns Mount
    by BeauHD on 19/11/2025 at 10:24 pm

    Nvidia blew past earnings expectations with soaring revenue and profit, easing fears of an AI bubble and reinforcing its position as the engine of the global AI boom. From a report: Nvidia's sales grew 62% year-over-year to $57 billion in the October quarter, ahead of the $54.9 billion Wall Street had projected, signaling that demand for AI chips remains strong even as more questions emerge about whether returns from the technology will keep up with the pace of AI infrastructure investments. It posted profits of $31.9 billion, up 65% from the year-ago quarter and also slightly above expectations. "Blackwell sales are off the charts, and cloud GPUs are sold out," Nvidia CEO Jensen Huang said in a statement, a message that echoes his earlier arguments that fears of an AI bubble are overblown. The company also posted stronger-than-expected sales guidance of around $65 billion for the fourth quarter, another indicator that the AI spending spree isn't slowing anytime soon.

  • Dutch Hand Back Control of Chinese-Owned Chipmaker Nexperia
    by BeauHD on 19/11/2025 at 10:07 pm

    An anonymous reader quotes a report from Bloomberg: The Dutch government suspended its powers over chipmaker Nexperia, restoring control to its Chinese owner (paywalled; alternative source) and defusing a standoff with Beijing that had begun to hamper automotive production around the world. The order that gave the Netherlands powers to block or revise decisions at Nexperia was dropped as "a show of goodwill," Economic Affairs Minister Vincent Karremans said Wednesday in a post on social media site X. Bloomberg had reported earlier this month that the Netherlands was prepared to take the step if chip deliveries from the company's site in China could be confirmed. The move marks a significant de-escalation of a dispute that underscored the global nature of supply chains and highlighted Beijing's growing leverage. Even though Nexperia's chips aren't advanced and the company only operates one facility in China, the spat disrupted automakers from Honda Motor Co. to Volkswagen AG. The reversal by the Dutch government was set in motion after a breakthrough in talks earlier that involved Chinese and Dutch officials, with input from Germany, the European Union as well as the US. To help resolve the stalemate, Beijing agreed to loosen export restrictions from Nexperia's Chinese plant, the largest of its kind in the world. The Dutch economic affairs ministry sent a delegation to Beijing this week to negotiate a "mutually agreeable solution," according to a ministry statement. Read more of this story at Slashdot.

  • Can Chinese-Made Buses Be Hacked? Norway Drove One Down a Mine To Find Out
    by msmash on 19/11/2025 at 9:22 pm

    An anonymous reader shares a report: This summer, Oslo's public-transport authority drove a Chinese electric bus deep into a decommissioned mine inside a nearby mountain to answer a question: Could it be hacked? Isolated by rock from digital interference, cybersecurity experts came back with a qualified yes: The bus could in theory be remotely disabled using the control system for the battery. The revelation, presented at a recent public-transport conference, has spurred officials in Denmark and the U.K. to start their own investigations into Chinese vehicles. It has also fed into broader security concerns across Europe about the growing prevalence of Chinese-made equipment in the region's energy and telecommunications infrastructure. The worry is the same for autos, solar panels and other connected devices: that mechanisms used for wirelessly delivering system updates could also be exploited by a hostile government or third-party hacker to compromise critical networks. [...] The Oslo transport authority, Ruter, said the bus's mobile-network connection via a Romanian SIM card gave manufacturer Yutong access to the control system for battery and power supply. Ruter said it is addressing the vulnerability by developing firewalls and delaying the signals sent to the vehicles, among other solutions. Read more of this story at Slashdot.
