Windows Backdoor 'Sleepwalker' Hides in Memory Until Activated by a 'Magic Packet'

✇Slashdot
著者: BeauHD

🤖 AI Summary

タイトル:Windowsバックドア「Sleepwalker」は魔術パケットにより起動され、メモリに潜んで指令を待つ

要点:
1. バックドア「Sleepwalker」は特定のネットワークパケット(「魔術パケット」)で起動し、それが到着するまで静かにメモリに潜んでいる。
2. 対象となるパケットには、バックドア独自の指令言語で書かれた短いプログラムが含まれる。
3. 指令言語は23インストラクションで構成されており、コードを直接メモリ上で実行したり、データを移動したりできるなど機能が豊富。
4. 対象となるホストアドレスとしてVMwareのVMCI(Virtual Machine Communication Interface)が使用できることも特徴的。
5. バックドアは64ビットWindows DLLファイル内に隠され、Microsoftのdpapi.dllを模倣している。実際のdpapisvc.dllへのリダイレクトを試みるなど、高度な脱皮技術を持つ。

詳細:
- 通常バックドアはコマンド&コントロールサーバーと通信し始めるが、「Sleepwalker」はネットワークトラフィックに潜んで特定のパターンを見つける。
- テクニカル分析では、感染されたまま外部に接続を行わないため、一般的なセキュリティツールには見つからない可能性があることが指摘されている。
"The Register has a story about a Windows backdoor that waits silently in memory for a 'magic packet' before springing into action," writes Slashdot reader fred133. "No outgoing traffic, just waiting..." From the report: Like a sleeper cell awaiting activation, a never-before-seen Windows backdoor dubbed Sleepwalker waits silently in memory for one specifically crafted network packet to wake it up and deliver commands using the malware's 23-instruction language. The commands can do everything from running code directly in memory to moving data off the computer. Malware researcher Dominik Reichel discovered the passive backdoor, which also has its own command language, and detailed Sleepwalker in a technical analysis on Monday. "What makes it worth writing up is what that packet carries: not a readable command, but a short program written in a command language of the backdoor's own design," Reichel said. "Its 23 instructions cover scheduling, several ways to move data, staged file delivery and running code directly in memory. Recovering the encryption key is not enough to understand one of these programs. The internal command language must be reverse engineered as well." In addition to having its own command language, it's also notable that the remote host can be a VMware VMCI target instead of a normal network address. "Taken as a whole, the approach here is consistent with a targeted, well-resourced operation rather than an opportunistic one," Reichel wrote. The malware, hidden inside a 64-bit Windows DLL file, impersonates Microsoft's dpapi.dll, part of Windows' data protection API for protecting sensitive data. It exports the same seven functions as the real dpapi.dll, but attempts to forward calls to a file named dpapisvc.dll, which is not a real Windows component. The file also has a forged ESET Management Agent version resource, and loads via side-loading into ERAAgent.exe, the Windows executable for ESET Management Agent. After confirming that its host process is named ERAAgent.exe, Sleepwalker goes to sleep inside the computer's memory, which also helps it remain hidden from traditional anti-virus tools. Unlike most backdoors, which call back to an attacker-controlled command-and-control (C2) server and start receiving commands, Sleepwalker lies in wait, checking every packet that passes through the network looking for a specific pattern - this is called a magic packet. Once it sniffs out a packet that matches the exact pattern, the backdoor decrypts the data and treats it as a command. "Because the backdoor never sends anything out on its own and does not open any obvious listening port by default, tools that watch for connections to known-bad domains or unusual outbound traffic will not see anything unusual," Reichel wrote. "The absence of outbound connections to known-bad infrastructure does not rule out an infection, either. A machine can be fully compromised by this backdoor while producing nothing at all for a network monitor to flag."

AliExpress Leverages User Audio Systems For Fingerprinting

✇Slashdot
著者: BeauHD

🤖 AI Summary

AliExpressはユーザーの音響システムを利用し、指紋認証を行う手法を採用していることが明らかになりました。開発者の「laserphile」によると、アリエクスプレスのサイトがWebAudio APIを使用して、不可聴の音声信号を放送し、それぞれのデバイスが信号を処理する微妙な違いを測定することで、ユーザーを特定する独自の指紋を作成しているとのこと。Bluetoothヘッドフォンが一時的に停止することや、画面サイズやネットワークデータなど、幅広い情報も収集されていると報告されています。

この手法は不可視かつ非同意で行われており、プライバシーに重大な影響を及ぼします。開発者は問題を解決するためにはプライバシーオリエンテッドのブラウザを使用することを推奨しています。FirefoxやBraveといったブラウザでは、この種の追跡を制限またはブロックすることが可能です。

要するに、AliExpressはユーザーのデバイス情報を無断で収集し、指紋化することでトラッキングを行っているという点が本記事の主な内容です。
A developer says AliExpress is using the browser's WebAudio API to help fingerprint users by playing inaudible audio and measuring tiny differences in how their devices process it. CyberNews reports: The developer, "laserphile," wrote on their blog that they recently ran into some weird issues with their Bluetooth headphones. They couldn't play music via their phone when, at the same time, the AliExpress website was open on their PC. The headphones, laserphile explained, support multipoint Bluetooth audio so they can be connected to the PC and phone at the same time, for instance, playing music on the phone and announcing notifications through the PC. "Shortly after loading the AliExpress homepage, audio from my phone would stop playing. Closing the AliExpress tab fixes it immediately," the developer said in the blog post. "Muting the tab/Firefox/Windows does not help, and there is no visible video, music, or other media playing on the page. This seemed suspicious enough to investigate." It turns out that Alibaba has been secretly leveraging AliExpress users' audio systems to track them and build detailed fingerprints of them. [...] The AliExpress site was using the browser's WebAudio API to run invisible sound waves at zero volume. By measuring tiny hardware differences in how each PC processed those signals, the site created a unique digital fingerprint to track devices -- without user knowledge or consent. The secret audio path froze the developer's Bluetooth connection while covertly scraping hardware memory, screen dimensions, and network data in the background. The data collection extends beyond audio. Further inspection revealed that the same scripts also measure canvas, WebGL, hardware specs, WebRTC, mouse/touch events, and automation indicators. All of these form a broad device fingerprint that is sent back to Alibaba's telemetry servers. The simplest fix is to use a privacy-focused browser such as Firefox or Brave, which can limit or block this kind of fingerprinting. Brave goes further by randomizing fingerprint data and blocking the AliExpress tracking scripts involved.

World's Oceans Hit Highest Temperature On Record As El Nino Grows

✇Slashdot
著者: BeauHD

🤖 AI Summary

海は記録を超えるほど暖かくなり、人為的な気候変動と進行するエルニーニョ現象の影響を受けています。欧州宇宙探査技術庁(Copernicus)の気候サービスによると、太平洋極地以外の平均表層水温は9月24日に21.1℃に達し、過去最高を更新しました。これは3回にわたって2024年3月に記録された21.09℃を超えたものです。

データは海面下10メートル(約32フィート10インチ)の温度を使用し、浮標や船舶、衛星からの測定を組み合わせて得られた世界全体の推計値です。専門家たちは記録更新のタイミングが注目を集めています。通常、海面温度は毎年3月か4月に最も高い値となりますが、これは南半球の夏終わりと一致しています。現在エルニーニョ現象のピーク時期にはまだ早いにもかかわらず、海洋がすでに高温になっていることは懸念材料となっています。

南半球が地球の大半を覆しているため、平均海面温度に大きな影響を与えます。サウスハンプトン大学海洋研究所のジェイムズ・グリスト准教授は、「記録更新が既に発生していることは、エルニーニョの強さの早期指標である」と述べています。「全てが同じ状況であれば、2027年3月か4月にも再び記録を更新する可能性があります」とも付け加えました。
An anonymous reader quotes a report from the BBC: The world's oceans are hotter than ever recorded, new data suggests, as they suffer from human-caused climate change and the growing El Nino weather phenomenon. The average surface temperature of the planet's seas outside the polar regions hit 21.1C (70F) on Saturday, according to figures from the European Copernicus climate change service. That edges past the 21.09C recorded on three separate days in March 2024, and is far above average for the time of year. [...] The data is based on sea temperatures 10m (32ft 10in) below the surface, using measurements from buoys, ships and satellites, which are combined to produce a global estimate. While the margin of record is currently very small and any global estimate comes with uncertainties, scientists say its timing is particularly notable. Average worldwide sea temperatures tend to reach their yearly peak in March or April, which corresponds to the end of summer in the southern hemisphere -- and not in August. The southern hemisphere contains more of the planet's ocean surface than the northern hemisphere and so exerts a bigger influence on average sea temperatures. What is especially concerning to scientists is that the oceans are already so hot when the natural El Nino weather phenomenon is still some way off its expected peak. "The fact that we are already breaking records is an early indicator of how strong the El Nino is becoming," said Dr Jeremy Grist, senior research fellow at the National Oceanography Centre in Southampton. "All things being equal we might expect the ocean temperature record to be broken again in March [or] April 2027," he added.

SEC Investigating Near-Implosion of AI Hedge Fund

✇Slashdot
著者: BeauHD

🤖 AI Summary

アメリカ証券取引委員会(SEC)は、AI関連のヘッジファンド「Situational Awareness」の近乎崩壊を調査し、主要なウォール街銀行に対し取引や借入金に関する情報提供を求めている。このヘッジファンドは元OpenAI研究者のレオポルド・アシェンブレンナーによって設立され、300億ドル以上の資産を管理していたが、流動性の不足により大規模な株式売却が迫られた。

SECは小投資家を保護するために金融市場を監視しており、損失を出した投資会社に対して定期的に民事訴訟を行っている。Situational Awarenessに対する調査はまだ初期段階で、罰則や処罰につながるとは限らないという。Situational Awarenessは2年前に設立され、AIのboomに乗って急速に成長したが、高株価のAI企業の売上が下落し、従来型テクノロジー企業の株価が上昇するなど、多重のリスクにより資金不足に直面し、最終的にシティレーンに株式を格安で売り渡さざるを得なかった。

この記事は Slashdot から引用しています。関連情報として、トランプ政権によるH-1Bビザ申請料金引き上げやアマゾンのハードウェア価格上昇なども参照できるという。
The SEC is investigating the near-collapse of AI-focused hedge fund Situational Awareness, sending subpoenas to major Wall Street banks for details about the fund's trades, borrowing, and communications with lenders. The fund, founded by former OpenAI researcher Leopold Aschenbrenner, managed over $30 billion and borrowed tens of billions more before leveraged bets unraveled, forcing it to sell most of its stock portfolio to Citadel at a discount. The New York Times reports: The subpoenas asked for details on the timing of Situational Awareness's trades and for its communications with lenders about the money it was borrowing, also known as "leverage," two of those people said. The subpoenas additionally warned the banks to preserve any information regarding the San Francisco hedge fund. The S.E.C. oversees financial markets with an eye toward protecting small investors, and has brought civil cases regularly against investment firms that produced large losses. Any investigation into Situational Awareness would be at its earliest stages, and it's no guarantee that it would lead to fines or other punishment. The hedge fund has not been accused of wrongdoing. [...] Situational Awareness had a fast rise and an even quicker retreat. Founded just two years ago by Leopold Aschenbrenner, a former researcher at OpenAI, it rode the A.I. boom to soaring investment returns. To achieve those results, however, the fund relied on heavy borrowing, as well as complicated and expensive financial instruments that magnify gains -- and losses. The latter piled up quickly last month when the stock prices of publicly traded, high-flying A.I. companies dipped. At the same time, shares in more traditional technology companies -- which the hedge fund had been betting against -- rose, compounding the problem. Situational Awareness was forced into a fire sale. It wound up selling most of its stock portfolio to a rival, Citadel, at a discount.

Trump Admin Moves to Impose More Than $100K Fee For H-1B Worker Visas

✇Slashdot
著者: BeauHD

🤖 AI Summary

トランプ政権は、特定の新規H-1Bビザに対する年金額103265ドルを永久化する方針である。これにより、技術、教育、研究分野で高度な技能を持つ外国人労働者の雇用に依存する企業には大幅なコスト増が見込まれる。Reutersによると、「裁判所は今年6月にこの年金を違法と判断し、政権が収受できなくなった」とのことだ。また、ボストンの上告法院ではこの決定の検討が行われており、別の法院では主要企業団体による年金に対する挑戦に対する裁判官の妥当性も審理中である。

トランプ氏の暫定的な年金増額は今年9月に期限切れとなり、1年前から発布された。土曜日に連邦登録雑誌に公表された国土安全保障省の提案案によると、この年金が永久化される可能性がある。年内には finalize されるとみられる。

H-1Bプログラムは、米国企業が専門分野の研修を受けた外国人労働者を雇うためのもので、年間65,000件のビザと、修士以上学位を持つ2万件の別枠がある。これらのビザは通常2000ドルから5000ドル程度の手数料しかかかっていなかったが、トランプ氏の指示により大幅に増額された。

この年金は、留学生ビザを保有する外国人市民に適用されず、また現在のビザの更新に対しては適用されない。
The Trump administration is proposing to make permanent a $103,265 fee on certain new H-1B visas, dramatically increasing costs for employers that rely on highly skilled foreign workers in tech, education, and research. "A federal judge in June ruled that the fee was illegal and blocked the Trump administration from collecting it," reports Reuters. "A Boston-based appeals court is reviewing that decision while a different court considers whether a judge properly rejected a challenge to the fee by a major business group." From the report: Trump's temporary fee increase expires in September, one year after it was issued. The proposed rule by the U.S. Department of Homeland Security, posted in the Federal Register on Monday, would make a fee of $103,265 permanent. It could be finalized by the end of the year. The H-1B program allows U.S. employers to hire foreign workers with training in specialty fields and offers 65,000 visas annually, with another 20,000 for workers with advanced degrees, approved for three to six years. Those visas typically came with fees between $2,000 and $5,000 before Trump's order. The fee would not apply to visas granted to foreign citizens already in the United States on student visas, who make up a large share of new H-1B recipients, or to renewals of current visas.

Nvidia Senior Manager Linked To Supermicro Scheme Smuggling AI Servers To China

✇Slashdot
著者: BeauHD

🤖 AI Summary

台湾当局对涉嫌非法向中国出口高端AI服务器并伪造文件掩盖违规行为的9人提起诉讼,其中包括一名Nvidia高级经理和两名Supermicro员工。这些人在美国实施出口管制的情况下,试图规避相关法规。

据路透社报道,检察官没有透露姓名,但确认嫌疑人因“信任侵犯和伪造文件”被捕。目前尚有一名与案件有关联者潜逃,涉嫌挪用分销公司资金,协助中国获取受限的Nvidia芯片。

2022年起,美国要求出口半导体到中国需获得许可,目的是通过领先中国在AI竞赛中保护国家安全。Supermicro创始人Wally Liaw因涉嫌自2024年以来向中国非法输送价值约25亿美元的AI服务器被捕后,台湾展开了独立调查以了解详情。

调查显示,共谋者试图伪造文件,使130台B300服务器看似在台湾设施中安装和使用。但实际上74台最终被出口并交付给中国客户,另有56台则因海关检查异常未能交货。据台湾官员称,Nvidia经理与Supermicro员工在不同层面进行勾结以谋取巨额利润,非法出口高端服务器,增加了企业合规成本,并严重损害了国家的国际声誉。

Supermicro对此表示,公司将致力于保护先进技术和知识产权,并将继续与台当局合作,强化安全措施、提升供应链透明度和执行出口管制法律。
An anonymous reader quotes a report from Ars Technica: Taiwan has indicted nine people -- reportedly including an Nvidia senior manager and two Supermicro employees based in the country -- who allegedly helped forge documents to cover up illegal exports of high-end AI servers to China in violation of US export controls. On Monday, Reuters reported that prosecutors in Keelung did not release any names but confirmed that the suspects were "charged with breach of trust and document forgery." One suspect linked to a related case remains at large, accused of the "siphoning of funds from a distributor company involved" in helping China get access to restricted Nvidia chips. Since 2022, the US has required a license to export semiconductors to China, with the intent of protecting national security by staying ahead of China in the AI race. But after the US arrested Supermicro co-founder Wally Liaw in March for allegedly funneling $2.5 billion in restricted AI servers to China since 2024, Taiwan launched a separate probe to learn more about the scheme. Taiwan's investigation found that co-conspirators attempted to falsify documents to make it appear that 130 B300 servers were installed and in use at a Taiwan facility. But 74 of those servers "were ultimately exported and delivered to Chinese customers," Reuters reported, while the rest, 56, were intended to go to China but were blocked once Taiwanese customs officials "detected irregularities." According to Taiwan officials, Nvidia's manager and Supermicro employees "colluded with one another at various levels for enormous profit, illegally exporting high-end servers, increasing corporate compliance costs, and severely damaging our nation's international image." Supermicro said in a statement to PCMag: "Supermicro is committed to protecting our advanced technologies and intellectual property. We are working closely with Taiwanese authorities on recent events, which underscore the importance of continued collaboration across industry and government to strengthen safeguards, enhance supply chain visibility, and facilitate the enforcement of export control laws."

China Delays Ambitious Chang'e 7 Lunar Mission Until 2027

✇Slashdot
著者: BeauHD

🤖 AI Summary

中国は8月24日の打ち上げを延期し、嫦娥7号月面ミッションを2027年まで延期すると発表しました。この延期は悪天候によるもので、中国の宇宙飛行士団(CMSA)は「絶対的な安全」が求められるためと説明しています。科学アメリカンによると、米国と中国は月面有人帰還を目指している競争にあり、米国は1960年代に実現し他国では未達成のこの目標に向けてそれぞれ努力を続けているのです。

嫦娥7号は Shackleton 峡谷で氷結した水を探すために設計されており、ここは月南極近くの21キロメートル四方の坑です。これはこれまで任何の有人探査機が立ち寄ったことのない地域であり、水を探偵することが長期的な月面居住に不可欠な要素となっています。

Ars Technicaによると、延期の主因は台風ナーラによるもので、海南島と大陸中国を隔てる水路で進む台風ナーラは最大45マイルの風速を持っています。また、次回の打ち上げ窓口が2月や3月になるのは、極地着陸区の日照条件と90日間の月周観測が必要なミッション計画による可能性が高いです。

このミッションは米国と中国が月面基地を建設するために争う重要な地区に焦点を当てているため、どちらの国の先発権が争点となっています。
China has delayed its ambitious Chang'e 7 lunar mission until at least 2027 after scrubbing an August 24 launch. Poor weather conditions were likely a factor, with China's Manned Space Agency (CMSA) saying the decision reflects the need for "absolute safety." Scientific American reports: China and the U.S. are in a race to send humans back to the moon, a feat that that U.S. accomplished in the 1960s and that has never been achieved by any other country. Chang'e 7 is to play to a crucial part in China's ambitions: the probe is designed to search for frozen water in the Shackleton Crater, a pit that spans some 21 kilometers (13 miles) and sits beside the lunar south pole. No spacecraft has ever landed in that region, which scientists consider to be among the likeliest places to find water on the moon. Locating water that can be used by humans is vital to establishing any long-term lunar presence. NASA and China are eyeing the region to establish a crewed base -- and because this real estate is so precious, it matters who gets their first. Ars Technica notes in its reporting that the delayed launch was "most likely" due to Typhoon Narra, "which has 45 mph winds (equivalent to a moderate Tropical Storm) and continues to meander around in the waterway separating Hainan Island, where the spaceport is located, and mainland China." As for why the next launch window won't open until next February or March? "It likely is a combination of factors, including sunlight conditions in polar landing zones as well as the mission plan that requires a 90-day lunar orbit reconnaissance before landing," reports Ars. There's also a possibility, albeit an unlikely one, that "some technical issue was discovered at the last minute with either the complex Chang'e 7 payload, or the rocket."

著者: BeauHD

🤖 AI Summary

アルツハイマー病の初めての血液検査がFDAで承認されました。このテストは40歳以上の症状のある患者に適用でき、アミロイドとタウというタンパク質のバイオマーカーを一つの血液サンプルから測定します。 PrecivityAD2は、これらを迅速に評価する単一血液検査で、プラズマAB42/40とp-tau217/np-tau217を質量 espectrometry を使用して測定し、結果を陰性、おそらく陽性、またはAD陽性とスコアリングします。この検査は一か月前にFDA承認された最初のものであり、現在3つ目の承認を得ました。PrecivityAD2は1,142人の症状のある成人を対象にした臨床検証研究で97.6%の精度を示しました。また、慢性腎臓病や糖尿病などの共病状態を持つ患者でも結果が一致しました。この検査は一般的な健康Screeningには適しておらず、認知機能の衰えがある患者向けです。これは早期診断、臨床試験の強化、精密医療と組み合わせ治療の基礎を築くために重要なステップとなるでしょう。
The FDA has cleared the first Alzheimer's blood test for symptomatic patients as young as 40. The test measures amyloid and tau biomarkers from a single blood draw and identified positive biomarkers with 97.6% accuracy in a validation study. New Atlas reports: PrecivityAD2 is a single blood test that quickly assesses the proteins amyloid and tau, using mass spectrometry to measure plasma AB42/40 and p-tau217/np-tau217. The results are then scored, qualifying as negative, likely positive, or positive for AD. "Just over a year ago, there were no FDA-cleared blood tests for Alzheimer's, and now we have three," Isobel Coleman, chief executive officer of the Alzheimer's Drug Discovery Foundation (ADDF), said in a statement. "This is a proof point that sustained, early investment in translational science plays a catalytic role in moving promising ideas from the lab to patients." In a recent clinical validation study, 1,142 symptomatic adults were tested using PrecivityAD2. The process accurately identified 97.6% of positive biomarkers. What's more, the results remained consistent even in patients with comorbidities like chronic kidney disease and diabetes, which can distort plasma amyloid samples. It's worth noting that the test isn't intended for general health screenings, but for patients who already show some cognitive decline. "As PrecivityAD2 and tools like it move further into clinical practice, they will enable earlier detection, sharpen clinical trials, and build the foundation for precision medicine and combination therapies," Coleman added.

Humanoid Robots Run 100 Meters Faster Than Usain Bolt's Record Pace

✇Slashdot
著者: BeauHD

🤖 AI Summary

humanoidロボットが北京で開催された「世界 humanoid ロボット大会」の100メートル競 walk 中、ウサイン・ボルトの世界記録より速い9.39秒で走破したというニュースです。開発元は北京市 humanoid ロボットイノベーションセンターで、同ロボットが Honor の Lightning に先行しました。大会では種目も多岐にわたり、サッカー、卓球、ボクシングなども行われます。

しかし、現段階では商業的な用途には使用されない見込みです。競走後に直接障害物に衝突し、一部は人間の援助を必要としながらコースから運び出されたという点に注意が必要です。

前年の大会では Tiangong Ultra が21.5秒で優勝していました。また、北京ではロボットハーフマラソンも開催され、Lightning が50分26秒で優勝しました。
この成果は昨年と比べて著しい進歩ですが、まだ商業的な活用には至っていないようです。
Two humanoid robots competing at the World Humanoid Robot Games in Beijing on Saturday ran the 100-meter dash faster than Usain Bolt's 9.58-second world-record time. "[T]he Tiangong Ultra humanoid robot completed the 100-meter dash in 9.39 seconds during a preliminary heat," reports Engadget. "Developed by Beijing Humanoid Robot Innovation Center, the record-holding robot overtook Honor's Lightning robot, which completed the sprint in 9.47 seconds. From the report: Despite the impressive finish times, don't expect these humanoid robots to be used for any commercial purposes yet. After their sprints, they slammed directly into pads and some even required human assistance to be stretchered off the course. However, it's still a major improvement from last year's inaugural World Humanoid Robot Games, where the Tiangong Ultra won the 100-meter dash in 21.5 seconds. Beijing has also hosted a humanoid robot half-marathon, where Honor's Lightning won in 50 minutes and 26 seconds, which also beat the pace of another human world record. "The World Humanoid Robot Games in Beijing kicked off August 22 and will run until the 26, hosting thousands of robot participants competing in more than just track and field events, including soccer, table tennis and boxing," adds Engadget.

🤖 AI Summary

Dr. Dreは、ギタリストやエミネムのヒット曲「The Real Slim Shady」など多くのヒット曲を生み出した7回のグラミー賞受賞プロデューサーで、人工知能(AI)を使って音楽を作ることに積極的です。ニューヨーク・タイムズのインタビューで、DreはAI反対派を「新しいことを学ぶのが難しい人々」だと表現しました。「私は脅威とは見えないし、作曲が苦手な人だけがそれを脅威だと感じる」と語りました。

また、ビーツ・バイ・ドレとの共同経営者であるジェミー・イオヴァインもAIの欠点はないと主張します。「良い音楽を作るために gifted な人々にAIを提供すれば、より良いアルバムが作れます」と彼は述べました。Dreは、自身もAIを使って「これまでの自分の作品との比較」をするために利用していると語っています。

さらに、多くのプロデューサーがAIを使用していることを認めていないにもかかわらず、「隠れたAIプロデューサー」と呼ばれるIovineはティムバランもその一人だと述べています。
An anonymous reader quotes a report from Gizmodo: Dr. Dre, the pioneering rapper and seven-time Grammy-winning producer behind hit songs like Tupac's "California Love" and Eminem's "The Real Slim Shady," is very much pro using artificial intelligence tools to make music. In an interview with the New York Times, Dr. Dre and Interscope Records co-founder Jimmy Iovine spoke about artificial intelligence's recent foray into music production, with the producer characterizing those who oppose AI song generation tools as "afraid of learning new things." "I don't see it as a threat. I think the only people that see it as a threat are the people who have trouble creating," Dr. Dre said. "I had a discussion with a few people a few days ago. They were against AI, and I'm like, 'OK, you sound like the person that would have been against the drum machine when it came out.' Or synthesizers, right?" [...] Iovine, the music executive and Dr. Dre's partner in Beats by Dre, for his part, says he doesn't "see the downside at all." "There will be some crappy music. There's crappy music now," Iovine told the NYT. "In the studio, when gifted people have AI, they're going to make better records." Dr. Dre said he uses AI in producing "as a tool to see what it would do with what I just did." The award-winning producer also said he is definitely not alone among his peers in his stance on AI either: many producers use AI but fear to admit it. Iovine calls them "closet AI producers," and says Timbaland, the four-time Grammy-winning singer-producer behind a long list of hits like "Promiscuous" with Nelly Furtado, is also one.

🤖 AI Summary

ニューヨークがサンフランシスコベイエリアを技術労働力市場の最上位から取り代えたという報告書があります。不採用ラッシュにより、ベイエリアの技術労働力は2022年から2025年に6%減少しましたが、ニューヨークは8%以上増加し、394,300人に対してベイエリアは375,730人を記録しました。CBREのコリーン・ヤスウコチ氏は、「AI産業と革新的な活動の中心地としてベイエリアが維持される可能性が高いですが、過去のサイクルから見れば、その成長は主要市場へと広がるでしょう」と述べています。
fjo3 shares a report from SFGATE: The San Francisco Bay Area, epicenter of the artificial intelligence boom, is home to a massive amount of tech workers employed by some of the world's most valuable companies, from Apple to Nvidia. But for the first time, New York has eclipsed the Bay Area as the home of the largest "tech talent workforce," a report by real estate and investment firm CBRE shows. The firm has published the annual report for 13 years. Last year, the New York Metro Area's tech talent workforce reached 394,300, surpassing the Bay Area's 375,730, according to the report. Fueled by mass layoffs, the Bay Area's tech talent workforce dropped by 6% from 2022 to 2025. New York's tech talent workforce, on the other hand, grew by more than 8% during that period "The Bay Area is likely to remain ... the central location for the AI industry and for innovation. But as we've seen during past cycles, as it tends to grow, that spreads out to all the key markets," Colin Yasukochi, executive director of CBRE's Tech Insights Center, said during a news conference Tuesday.

'Off the Charts' El Nino Is Already the Strongest Since Records Began

✇Slashdot
著者: BeauHD

🤖 AI Summary

エルニーニョ現象が急速に進展し、既に記録データのある期間の中で最も強力なレベルを達成しています。コロンビア大学のジェームズ・ハンセン氏は、Newsletterで「エルニーニョは繁栄し、記録を超えた」と述べています。最大効果は数ヶ月先になるものの、「我々が持っている最良の指標(東部熱帯太平洋上層300メートルの平均温度)は1997-98年に見られたスーパーエルニーニョを越えている」と彼は言います。

気象学者たちは、この現象が過去の「スーパーエルニーニョ」を超えるかどうか意見が分かれていますが、一部の研究者によれば、予測値は前例がないほど強力で、最も強力な現代の現象になる可能性があります。メート・オフィス(英国気象庁)のアダム・スクアイフ氏は、「このエルニーニョの信号は我々の予報の中でこれまで見たことのないほど強い」と述べています。「もし予測が正確であるとすれば、2026年は近年までのエルニーニョ現象やその世界規模の影響を大幅に上回るでしょう」。

英国ニューキャッスル大学のヘイリー・フォウェル氏によれば、この発展中のスーパーエルニーニョは歴史的なイベントを超える可能性もあるとし、「1877-1878年のエルニーニョが広範囲に影響を及ぼしたように、5,000万人(当時の世界人口の3~4パーセント)が死亡するなど大規模な犠牲が出たことから推測される」と述べています。
A rapidly developing El Nino is already reaching record-setting levels for this time of year and is expected to intensify further over the coming months. "The El Nino has blossomed. It is off the charts. Usual measures of El Nino have blown past prior record levels in the period with good data, even though maximum effects are still several months in the future," writes renowned climate scientist James Hansen at Columbia University in New York in a newsletter sent today. Climate scientists disagree over whether it has already surpassed previous "super El Nino" events on every metric, but several say the signal is unprecedented in forecasts and could ultimately become the strongest modern event on record. New Scientist reports: There are different ways of measuring El Ninos, which occur when warm surface waters spread eastwards along the equator across the surface of the tropical Pacific Ocean. Hansen thinks the best measure is how much warmer than usual the upper 300 meters of the eastern tropical Pacific becomes. "Our preferred metric, the heat anomaly in the upper 300 meters of the Equatorial Pacific Ocean... already exceeds the 1997-98 super El Nino," he writes. [...] What's clear is that this developing super El Nino will soon exceed previous events on all measures. "I have never seen an El Nino signal this intense in our forecasts," [Adam Scaife at the Met Office, the UK's national weather service] said in a statement released today. "If the forecast is accurate... then 2026 will far exceed our recent experience of El Nino and its worldwide climate influences." While Hansen is comparing the developing super El Nino to other modern events for which we have direct temperature records, Hayley Fowler at Newcastle University in the UK thinks it could also exceed historical events suspected to be even larger. "The super El Nino evolving in the Pacific will likely be the biggest ever recorded, reaching or exceeding the levels of the 1877-1878 El Nino which caused widespread impacts, including famines and around 50 million deaths (3-4 percent of the global population at the time), mostly across Asia and South America," Fowler said in a statement.

China Joins Europe In Scrapping Windows For Linux

✇Slashdot
著者: BeauHD

🤖 AI Summary

中国は欧州に追随し、WindowsをLinuxに切り替える動きが進んでいる。

1. 中国政府の機関が、Windows 10 China Government Editionから中国製のLinux Distributionへと移行 allegedly 指令された。この決定は、アメリカ企業に対する信頼の欠如(特にウイルスソフトやサービス)から来ている。
2. これはデジタル自立性を追求する政策の一環であり、以前から政府系システムで外国技術の代替品として国内開発のオープンソースを使用しようと試みていた。
3. この移行は容易ではなく、機関がWindowsからLinuxへ切り替える際には、アプリケーションテスト、周辺装置とドライバの検証、身元確認システムの統合、文書フォーマット互換性など多くの課題がある。
4. 中国の主要なLinux供給会社であるKylin SoftwareとUnionTech Software Technologyの株価が上昇した。彼らのオペレーティングシステムは既に政府や国有企業向けのデスクトップおよびサーバー替わりとして準備されている。

この変更は、HuaweiのHarmonyOS 2もPCプラットフォームへの展開を目指しているという点でも注目される。しかし、この移行作業は簡単ではなく、中国政府は具体的な実施方法を明らかにしていない。
An anonymous reader quotes a report from ZDNet: According to a Bloomberg report, attributed to China's Ministry of State Security, the country has ordered some government agencies to drop Windows 10 China Government Edition for Chinese-made Linux distributions. Why not Windows 11? Because China, like many other non-US governments, no longer trusts American companies with their software and services. This approach is all about digital sovereignty. In addition, even before the recent trend of governments outside America moving away from Windows, Beijing has started a long-running push to replace foreign technology in sensitive systems with domestic, open-source alternatives. [...] The Chinese government did not specify which Linux versions would replace Windows 10. However, the stock prices of Chinese Linux suppliers, Kylin Software and Tongxin Software Technology (commonly known as UnionTech), immediately jumped. These companies' respective operating systems, Kylin OS (no relation to Ubuntu Kylin) and UnionTech OS (UOS), were already positioned as domestic desktop and server replacements for Windows in government, state-owned enterprise, and critical-infrastructure environments. [...] Huawei's HarmonyOS 2, which began as an Android variant but is now a proprietary mobile and Internet of Things (IoT) operating system, is also being developed into a PC platform. HarmonyOS 2 won't be deployed anytime soon. Kylin and UOS are the only mature desktops that are ready for institutional desktop deployments. [...] ... this transition won't be easy. For agencies now moving off the government Windows build, the issue will be more demanding than simply swapping one desktop interface for another. Migration requires application testing, peripheral and driver validation, identity system integration, document-format compatibility, staff retraining and, in many cases, replacement or adaptation of Windows-dependent line-of-business software. The report provides no details on exactly how this transformation will occur. But the speed of the shift suggests that these issues are already being addressed in China's centralized managed desktop stack.

Township Fights Nuclear Weapons Data Center By Passing a Moratorium on Electrical Infrastructure

✇Slashdot
著者: BeauHD

🤖 AI Summary

ミシガン州エピセリントーシャンの町議会は、大学とロスアラモス国立研究所が核兵器研究を支援する約12億ドルのデータセンター建設計画に反対し、「主要な電力インフラ構造」について6ヶ月間の待機期間(仮禁制令)を発表しました。この決定は、既存のデータセンタへの水供給サービス停止と併行しています。

町議会は8月18日の会合で、新規高電力消費地番号への電力インフラ構造の建設を180日間遅らせる決議を全会一致で採択しました。大学は去年、エピセリントーシャンでの2万2,000平方フィートの大規模データセンターの建設計画を発表し、その決定には地元住民が反対してきました。

この待機期間は、「ハイパースケールデータセンター」や「高度計算中心」といった高電力消費地番号向けの必要な電力インフラ構造に関わるものです。大学は8月中旬に、144エーカーのテキスタイルロードにある土地を選定し、その決定文ではデータセンターが「世界を変える能力」があると強調しました。

一方で、ロスアラモス国立研究所は以前に発表しており、このデータセンターは戦争での標的リスクになり得ないものであり、危険な核物質を保管していないという点を示唆しています。しかし、町議会のブレンダ・ストンボロー議長は地元住民の環境への懸念を無視していると批判しました。

この待機期間中に、地元の電力当局が音響汚染や既存顧客への影響について調査することが求められています。町議会は大学からの情報提供不足に対して不満を表明し、大規模な電力トランスファーメンターの画像を使用して、その規模と透明性の欠如を示唆しました。
Ypsilanti Township, Michigan, has imposed a six-month moratorium on "major electric utility infrastructure" in its latest attempt to delay a proposed $1.2 billion University of Michigan-Los Alamos data center that would support nuclear-weapons research. Township leaders, who have already paused water service for data centers, say the project has moved forward without adequate consultation and want more time to study noise, grid impacts, and other effects on residents. 404 Media reports: Last year, the university announced it was partnering with LANL on the construction of a massive 220,000 square foot hyperscale data center in Ypsilanti Township and residents have been fighting it ever since. During a meeting of the Township Board on August 18, the council unanimously passed a resolution that will delay the construction of new electrical infrastructure for 180 days. Data centers need a lot of energy, and Michigan's power authority will have to build new substations in the Township to power the proposed facility. The moratorium asked the local power authorities to use the six month delay to study noise pollution and how the new infrastructure would affect existing customers. The moratorium is narrowly focused on "the nature and scale of electrical infrastructure necessary to serve new high-energy-demand land uses [...] including infrastructure associated, but not limited to hyper-scale data centers, mid-sized data centers, artificial intelligence computing facilities, and high-performance computational centers, industrial facilities, and other intensive electrical users." Earlier this month, the University of Michigan announced it had settled on a specific plot of land in Ypsilanti Township -- a 144-acre plot on Textile Road. In a press release about the decision, the University said the data center would have the "capacity to change the world" and insisted it would not be a "high value target risk" in a war, that it would not store any hazardous nuclear material, and was not a weapons production facility. LANL previously confirmed that the data center will be used for nuclear weapons research. Ypsilanti Township Supervisor Brenda Stumbo told WEMU news that the selection of the site was a "travesty of justice" because it ignores constituents' concerns about environmental impact. During the August 18 moratorium vote, the Board projected a large stock photograph of an electric substation behind its members. The photo was meant to remind people of the size of the incoming infrastructure and the lack of communication from the university about it. "This picture's really important to think about because U of M has been so crystal clear that they've been communicating to us abundantly -- which is not true," Township clerk Debbie Swanson said during the meeting. "That speaks to the lack of respect."

Apple Cuts Jobs In Siri, Vision Pro Immersive Video and Gaming Teams

✇Slashdot
著者: BeauHD

🤖 AI Summary

Appleは、 Siriの再構築やAI技術を活用した新たな製品開発に向けてリソースを転換することにより、200人以上の雇用を見直しています。これには、約100人のVision Proチームのポジション(特にゲーム部門と一部の浸ビデオスタッフ)が含まれています。Siriおよびソフトウェアチームにも約100人のポジションが影響を受けました。

Appleは声明で、「この変更により新しい役職を作成する一方で、一部の既存の役職に影響を受けることになります」と述べており、「これらの従業員の皆様には感謝します。彼らの転換期を通じてサポートいたします」とも述べています。

Siriの再構築は、新しいAI技術に基づくアシスタントの開発に関連しています。この変更には必要な専門知識の変更が必要で、既存の一部の役職が削除され、リソースが再配置され、更新されたSiriを支える新たな役職も作られます。

Intelligent Systems Experienceチームでの変更は、AI機能の開発を推進するためのチーム再編成の一環です。さまざまなグループがアプリやサービスにAI機能を導入する中で、Appleは優先事項と開発の加速を図るためにチームを再配置しています。この再編成は、既存の一部の役職が削除されるとともに新たな役職も作られます。
Apple is cutting more than 200 jobs as it shifts resources toward a rebuilt, AI-powered Siri and other future products. Roughly 100 positions are being eliminated from the Vision Pro organization, including much of its gaming team and some immersive-video staff. Another 100 cuts are hitting the Siri and software teams. Bloomberg reports: In a statement, Apple acknowledged that it was realigning some teams "to evolve our business to deliver the best experiences for our users." "While we will create new roles as part of this change, it will also impact a limited number of existing roles," the company said. "We are grateful to these team members for their contributions, and we are committed to supporting them throughout their transition, including opportunities to apply for other roles at Apple." The Siri reshuffling is tied to an upcoming AI-infused version of the assistant, which is built on a new technical architecture. That shift requires a change in the necessary expertise, prompting the company to eliminate a small number of existing roles, reallocate resources and create new positions supporting the updated Siri. The changes to the Intelligent Systems Experience team reflect an effort to reorganize work on AI-powered capabilities. As more groups bring AI functions to apps, features and services, Apple is realigning teams to match priorities and accelerate development. The restructuring will eliminate some existing positions while creating new roles.

Federal prosecutors have charged activist Samuel Tunick with obstruction after he gave Customs and Border Protection officers a duress passcode that wiped his GrapheneOS-powered Pixel during a border search. "His prosecution is one of the earliest known instances of the federal authorities charging a person with destroying evidence using a program designed to wipe a device clean after a specific code is entered," reports The New York Times. From the report: "Obstructing federal law enforcement is a serious matter that has serious repercussions," Theodore Hertzberg, the U.S. attorney for the Northern District of Georgia, said in a statement. "Individuals who destroy or attempt to destroy property, including data, to prevent lawful search and seizure should expect to face prosecution and punishment for their actions." A spokeswoman for U.S. Customs and Border Protection said in a statement that the agency had the authority to search the electronic devices of anyone entering or leaving the United States, regardless of citizenship, to enforce laws addressing terrorism, child exploitation, drug- and human-smuggling, visa fraud and national security threats. "The border search will only include an examination of information that is present on the device at the time it is presented for inspection," the spokeswoman said, adding that it searched the electronic devices of fewer than 0.01 percent of all arriving international travelers in the last fiscal year. "Just the knowledge that the government is peering into your private life in this way, trying to dig up dirt on you, even though it's unsuccessful, is creepy," Tunick said, in response to a question about how the charges have affected him. His message: "The government doesn't own our communications, our relationships, as hard as they might try to. We have to defend our fundamental right to privacy; otherwise we can't say that we really live in a democracy."

著者: BeauHD

🤖 AI Summary

AIの使用が学習に与える影響を調査した研究により、生徒たちが宿題で点数を上げる一方で、試験では下回るという結果が出た。

ストックホルム大学のストロムベルグと香港大学のレイ・ビクター・リーおよび呉営輝は、中国の12-18歳の約27,000人の生徒を追跡し、AIの使用状況を調査した。調査結果では、6ヶ月後には全科目で平均宿題点数が18%上昇し、各作業を完了するのに必要な時間も短縮された。

しかし、試験時にはAIを使用していた生徒たちは非使用者に20%下回る結果となった。かつては宿題の成績が試験の PERFORMANCE の予測子だったが、今では最も高い点数を得た生徒たちが逆に試験で悪い結果を出した。

この研究から、「AIは学習の効率性を向上させることができるが、その利用は賢明であることが必要だ」と結論付けている。学生たちは「自分の考えをしっかりと形成する前にAI生成の答えを求めないように」注意を喚起されている。
An anonymous reader quotes a report from The Economist: Students and school children are increasingly using artificial intelligence. A survey last year by Chegg, an ed-tech firm, found that 80% of rich-world undergraduates used it in their studies. More recent polls put the figure at 94% in Britain and 93% in Germany. Such widespread adoption has fueled concerns about the impact the technology might be having on learning. Teachers report marking identikit essays that they suspect are churned out by ChatGPT. Yet firm evidence on AI's educational effects has been lacking. David Stromberg of Stockholm University and Victor Lei and Wu Yanhui of the University of Hong Kong set out to fill the gap. They tracked 27,000 pupils aged 12-18 in China, where AI adoption has been fast. Around 80% reported using models such as Doubao and DeepSeek; the other 20% formed the control group. The results are eye-opening. After six months, pupils using AI saw their average homework score rise by 18% across all subjects. The time they took to complete each assignment fell from an average of 64 minutes to 45. But come exam time, the same students scored 20% below their classmates who had not called on AI's help. Homework scores once predicted exam performance; now those who score highest are, perversely, more likely to do worse in exams. The takeaway: "AI can boost learning productivity, but only for those who use the technology intelligently," reports The Economist. "Students must resist the temptation to reach for an AI-generated answer before thinking things through for themselves."
