🤖 AI Summary

50年以上にわたる探求の末、物理学者が「ゴリラグレープ」のような量子力の粒子であるグールンを主成分とする特殊な粒子(グールンボール)を見つけることに成功したという報告がある。この研究は北京での加速器実験で得られた結果に基づいており、中国の南京大学のジン・シャン博士らのチームが主導した。

彼らは高エネルギー粒子衝突を解析し、X(2370)と呼ばれる既知の粒子がグールンボールであるという強い証拠を得た。この粒子は夸力学間力媒介子からなる唯一の特殊な粒子であり、「ゴリラグレープ」の一種として知られる。

研究結果はアーカイブに投稿され、ブラジルで開催された高エネルギー物理学国際会議で発表された。ジン博士は南中国朝報紙に、「この成果は強力相互作用を説明する理論が最も厳しい検証を通過し、物理世界の理解の境界を拡張する可能性がある」と述べた。

この研究は約50年のグールンボール探査から最も明確な実験結果であり、夸力学間力媒介子が新たな物質形態を作り出すという長年にわたる理論予測を支持している。しかし、より多くの実験が必要で、さらにこの特殊なグールンボールの原型を確認し制約するためには「粒子 smashing」を行う必要があると指摘されている。
Gluons are the quantum 'Gorilla Glue' involved in binding quarks together, ScienceAlert reminds us. But for nearly 50 years, physicists have hunted for "glueballs", exotic particles predicted by this theory of the strong interaction — the only type of particle in nature composed entirely of force mediators: Now, a collaboration working at a collider in Beijing says it has the clearest evidence yet that a known particle called X(2370) is dominated by one of these elusive states... Physicists sifted through the wreckage of high-energy particle collisions to find strong evidence of this glueball, made predominantly of gluons — massless force carriers of the strong interaction between quarks... The new evidence for this exotic, unstable glueball's ephemeral existence comes from a recent preprint on arXiv, presented at the International Conference on High Energy Physics in Brazil... This collaboration uses the Beijing Electron Positron Collider II, a particle accelerator and collider that smashes electrons into their antimatter counterparts, called positrons, to probe perplexing particle physics. The resultant glueball is an "unprecedented form of matter," says Jin Shan, a particle physicist at Nanjing University and one of the research team's leaders. "It not only enables the theory describing strong interactions to pass its most rigorous test, but also vastly expands the boundaries of our understanding of the physical world," he told Fan Chen at South China Morning Post... Previously, in a study published in the journal Physical Review Letters in 2024, the researchers analyzed 10 billion meson decay events. They measured the X(2370) particle's mass and spin parity — a property that dictates its interactions and almost-instantaneous decay — for the first time, finding complete agreement between their experimental values and predictions. Now, they've identified its additional decay modes and determined its flavor-singlet nature, "the most important characteristic of a glueball...." The authors describe their work as the clearest experimental result to emerge from nearly 50 years of glueball searches, supporting the long-standing theoretical prediction that gluons can bind together into a new form of matter. The discovery ""highlights advances in technology and analytical techniques that have recently revealed another decades-in-the-making physics mystery," the article points out. "More experiments are needed to further confirm and constrain the prototypes of the highly esoteric glueball; in other words, more particle smashing."

SCO Successor Xinuos Asks Court to Rehear Its Claims Against IBM/Red Hat Over Project Monterey

🤖 AI Summary

SCOの継承者であるXinuosは、IBMとRed Hatに対するプロジェクト・モンテレー関連の主張について再審を要求し、長期にわたるLinux著作権の法的対立がついに終わりを見せる可能性があると報じられています。

2021年にSCOの後継者であるXinuosは、IBMがProject Montereyのコードを提供した際には非独占的なライセンスしか持っていないことから、IBMがその約束を破ったことを主張しました。Xinuosはニューヨーク南区地方裁判所に訴訟を提起し、2023年8月10日に二審法廷で再考の機会を求める権利があると判示されました。

二審法廷は、当初の法律文書により再検討する時期ではないと判断しました。Xinuosがライセンス問題ではなく所有樁に関する主張を行ったことを指摘しています。Xinuosは全判事会による再考を望んでいますが、これは通常起こらないほどまれなケースです。

関連記事:2000年にSlashdotではSCOの一つの社長とのインタビューが行われました。 SCOは約50年前に起きた「誰がUnixの所有者か?」という訴訟に関連していると指摘しています。

The long legal battle over ownership of Linux "is closer than ever to ending," reports the Register, "after a panel of three judges ruled a claim against IBM and Red Hat isn't valid, and that time has expired for further action." In 2021, an heir to SCO settled with IBM for $14.25 million — a sum that reflects the fact SCO had for years failed to produce strong evidence to back its claims. Another of SCO's legal successors, Xinuos, filed a new claim that IBM should be on the hook because Big Blue knew it did not own the code it contributed to Linux but instead had a non-exclusive license to use it. Xinuos argued that when IBM contributed Project Monterey code to Linux [25 years ago], it breached that license. Xinuos eventually took that argument to the US District Court for the Southern District of New York — and failed to convince it that IBM and Red Hat had a case to answer. Xinuos appealed, and on August 10th the United States Court of Appeals for the Second Circuit decided [PDF] not to revisit the District Court's decision, agreeing that the original legalese governing Project Monterey means it's too late to re-litigate the matter. The Appeals Court also agreed that Xinuos tried to frame the case as a licensing issue but failed, instead arguing that the issue was really about ownership. That ain't all, folks, because Xinuos intends to file a petition to have the case re-heard by the full bench of the Court of Appeals. That hardly ever happens, unless the court finds significant errors or major legal issues that make a rehearing worthwhile. Law firm Kaplan says the Second Circuit has allowed reviews of less than 0.03 percent of the cases it has handled. So perhaps this matter is now close to a final resolution. Back in 2000 Slashdot interviewed one of the presidents of SCO.

One-Third of Web Pages are Now Written With AI, Says Pew Research

著者: EditorDavid
2026年8月24日 13:34

🤖 AI Summary

Pew Researchのシニアデータサイエンティストが、過去5年間の50万件以上の英語ウェブページをAI検出ツールで分析し、どれほどのページがAIによって書かれているかまたは編集されているかを推定した結果、全体の10%のページにAI著者特性が見られると報告しました。ChatGPTのリリース後、新規ウェブページの3分の1以上がAIによって著作者または大量に編集された可能性があることが判明しました。

また、ウェブ上でのAI作成テキストは一様ではありません。.comドメインの約10%のページがAI作成の兆候を示す一方で、.org、.edu、.govドメインでは4.6%、1%程度にとどまっていることがわかりました。

さらに、現在のインターネットと2023年の状況を比較した結果、エムダッシュが2倍、オックスフォードコマースが増えた(63%)、AIによって頻繁に使用される言葉(例:「delve」、「interplay」、「testament」)の使用頻度が2倍になり、ネガティブな平行比較もほぼ3倍に増加したことが明らかになりました。
A Pew Research senior data scientist analyzed 500,000 English-language webpages from the past five years with an AI detection tool to estimate how many were likely written or edited by AI: Of all the pages in this sample, 10% show significant signs of AI authorship... If we filter old webpages out of our samples and look at only the pages published after the release of ChatGPT, the trend is even more pronounced. In the July 2026 snapshot, signs of AI authorship can be found in over one-third of pages published after ChatGPT was released. This is in line with other studies that have shown that large shares of recently published pages on the internet were likely written or substantially edited by AI. AI-authored text is not evenly spread across the web. When ChatGPT was first released, the kinds of linguistic patterns that can signal AI authorship appeared at similar rates across the main top-level web domains (.com, .org, .edu and .gov). But in samples from 2026, around one-in-ten pages with a .com domain show signs of AI authorship — about double the share on .org domains (4.6%), and 10 times the rate on .edu or .gov domains (both around 1%). They even identified specific ways online text has changed, "comparing the internet of today to a snapshot from 2023." Em dashes appear twice as often Oxford commas increased 63%. Words used more frequently by AI (like "delve," "interplay" or "testament") have more than doubled in usage. "Negative parallelism" comparisons ("it's not just X, it's Y") have nearly tripled.

Could Mecha Comet's Linux PC-Phone Hybrid Be the Future of Linux Smartphones?

著者: EditorDavid
2026年8月24日 11:31

🤖 AI Summary

「Mecha Comet」というLinuxを基盤としたPCとスマートフォンのハイブリッドデバイスがKickstarterで334万ドルを集め、10月や11月に発送される予定です。このデバイスは、4インチのAMOLEDディスプレイ、マイク、スピーカー、SIM Tray、USBポート2基、ミニHDMIポートを搭載しており、重量とサイズはスマートフォンより少し大きいです。

開発者はShoaib Merchantで、同社は300以上の拡張機能モジュールやキーボード、ゲームパッド、I/Oブレークアウトなどのオープンハードウェア提供を予定しています。デバイス自体はUSB PD(Power Delivery)により外部電源から起動することも可能です。

Mecha Cometはカスタムなハードウェア最適化されたLinuxディストリビューションを搭載しており、使い手が「ポケットに持ち運べる専用のLinuxターミナル」のように利用できます。このデバイスには内蔵NPUがあり、AIワークフローの実行も可能です。

開発者の一人は、この製品が「Linuxスマートフォンの未来」と主張しています。彼自身は、このデバイスを使って遠隔操作を行うことを計画しており、リモートアクセスやデジタルデトックスにも適しているとします。
3,346 backers pledged $1,198,844 on Kickstarter to build the (modular) handheld Linux computer, the Mecha Comet. It's slightly bigger and heavier than your smartphone, with a 4-inch AMOLED display and loaded up with things like microphones, speakers, a SIM tray, two USB ports and a mini HDMI port. There's three separate kill switches for wifi, microphone and camera — plus a "boot mode" switch for the SD card, and even three pins for instant access to its debug console. It's now expected to ship in October or November (and is still available for preorder). Snap-in extensions include a keyboard (with programmable colors for its backlit keys), a gamepad, and a special IO Breakout that exposes the 40 pogo pins for modules, sensors, and MCUs. They're all open hardware, and founder Shoaib Merchant says "I'm looking forward to more community designs over the upcoming months." He shows the screen in action in a video on Kickstarter, demonstrating native apps like Music, Notes, Settings, and Files — as well as a Terminal app running on its color screen. A Linux correspondent at How-To Geek notes its ships "with a custom, hardware-optimized Linux distro out of the box," so "it's like having a dedicated Linux terminal in your pocket." And they argue the new device "could be the future of Linux smartphones." I should also mention that you don't necessarily have to use the battery; it can power on over USB PD without one. Overall, you're getting the same I/O you'd expect from a computer in a smartphone-like form factor, complete with modular input devices — and it's running Linux under the hood. For me, that's the most innovative gadget I've seen in the Linux hardware space in a long time... It's powerful enough to run most Linux terminal apps, which opens up a lot of possibilities. You're also getting an NPU built right into the SoC, which opens up the possibility for on-device AI workflows — something not possible in budget smartphones. Now, I personally plan to use it for SSHing into my main computer and home lab and operating them remotely. That's also why I'll be putting the LTE modem in the M.2 slot rather than an SSD — mobile data means I can reach my machines even when there's no Wi-Fi around. I also showed it to my partner, and she sees this as the ideal minimalist phone for digital detoxing. There's a built-in media player, a basic notes app, and you can even run Spotify from the terminal if you want.

The Global Race To Make a Practical Quantum Computer Just Took a Big Leap Forward

著者: EditorDavid
2026年8月24日 08:53

🤖 AI Summary

量子コンピューターの実用化を目指すグローバルな競争が大きく前進したと、Tech.Slashdot は報告しています。Quantinuum社(本社:イギリス・ケンブリッジ、アメリカ・ブルームフィールド)が開発した Helios システムは、 trapped ions を用いて動作し、98 の量子ビットを操作する最大規模の trapped-ion 量子コンピューターです。これにより、従来の QCCD マシンでは実現不可能だった複数タスク同時処理が可能となりました。

Helios システムは、四方向 X 接続部というハードウェアと、最適なルートを計算する Helios ランタイムというソフトウェアにより、大きな進歩を遂げています。この技術革新により、Helios は現存の最大級のスーパーコンピューターでも可能な方法で時間とエネルギー効率よく量子計算を行うことが可能になりました。

ただし、これらの実験はランダムなベンチマークテストに過ぎず、科学や商取引における実用的な量子計算を行うには、数百万の量子ビットを必要とする可能性があります。
It's "radically different from other quantum computers" reports Phys.org. The Helios system uses trapped ions — charged atoms suspended in free space using electromagnetic fields. But it operates with 98 qubits — making it the largest trapped-ion quantum computer built so far. Quantinuum, the company behind the device, is based in Cambridge, U.K., and Broomfield, Colorado. It demonstrated earlier machines operating on 32 qubits in 2023 and 56 qubits in 2025... It relies on two major advances — one in hardware and one in software. First, the four-way X junction lets the system handle several tasks at once rather than one at a time, which is much faster. That was impossible in earlier QCCD [quantum charge-coupled device] machines, which could only move data back and forth in a single line or loop. Second, judicious use of the freedom offered by the two dimensions of the X junction relies on new classical control software called Helios runtime, which plans the smartest, fastest route for moving and processing the data. Together, these represent a substantial advance in the engineering of quantum computers. An important consequence is that Helios can perform computations that cannot be performed even on the largest supercomputers using known methods within reasonable amounts of time and power consumption. This demonstrates the ability of this device and its successors to surpass the computational prowess of classical computers — although their algorithms and hardware are rapidly advancing, too. Having said that, Helios' computations have just been random benchmark tests, so the practical importance of this leap forward is still limited. To perform quantum computations of practical importance in science and commerce, even the most optimistic estimates suggest that quantum computers must be enormously bigger and better — of the order of a million qubits.

Amazonの Twitch テーリングサービスがユーザーのストリームをAI製品に使用することなくライセンスや承認を得ること無く利用したとして、クラスアクション訴訟に見舞われました。Engadget によると、Twitchは先月、ユーザーが「チャンネルコンテンツを使用してAmazon全体での生成AIコンテンツモデルの訓練を行いたいか」を選べるオプトアウト機能を追加しました。しかし、Mike Minton(社長製品責任者)はViewerの質問に対し、「もしオプインだったなら誰も選ばないだろう」と述べ、設定はデフォルトで有効でありユーザーが参加しない場合はオプトアウトする必要があると説明しました。最新のクラスアクション訴訟では、TwitchとAmazonはストリーマーを「別々の商業AI製品の無料トレーニング素材」として利用したとして契約違反を主張しています。
A class action filed this week accused Amazon's Twitch gaming service of using video streams to fuel its AI products without licensing or obtaining permission, reports Engadget: Earlier this month, Twitch Support posted on X that it added an option to opt out of "having your channel content used to train generative AI content models across Amazon." Shortly after, Twitch hosted an episode of its recurring Patch Notes stream where Mike Minton, the company's chief product officer, said "if it was opt-in, nobody would opt in," when asked by a viewer why the Twitch settings for AI training aren't opt-in but instead enabled by default, requiring users to opt out if they don't want to participate. Now, the latest class action lawsuit claims that Twitch and Amazon committed a breach of contract when the companies decided to use its streamers as "free training stock for separate commercial AI products."

OpenAI Faces Safety Scrutiny After Introducing 'ChatGPT For Teens'

著者: EditorDavid
2026年8月24日 05:59

🤖 AI Summary

OpenAI は、13〜17歳向けの ChatGPT 版をリリースし、自殺や自己傷害に関する内容、浪漫的または性的なチャットなどに対する保護機能が強化された。Tech 分析家の Carmi Levy 氏によると、このバージョンはユーザーの年齢推定を行い、不適切な体験を防ぐとともに、学習に役立つ機能も追加しているという。

しかし、Levy 氏は、「AI が完璧ではない」と指摘。AI は一部のユーザーを誤認する可能性があり、保護機能を回避しようとする者もいるため、完全な安全性とは言えないと述べた。さらに、このバージョンは親が子供のオンライン活動を監視する意欲を減退させる可能性があるとして、「逆効果」であると批判した。

CNN によれば、OpenAI は ChatGPT の不適切な会話が若者に被害を与えているとして訴訟に直面している。新機能には、90 分間の利用後に休憩を促す機能や、「静寂時間」や「学習時間」などの設定があり、ChatGPT は既存の保護機能を改善し、ユーザーから個人的感情表現を防ぐとともに、プライベートまたは機密な画像のアップロードに注意を叫ぶ機能も追加された。

この新バージョンは若者のオンライン安全を高める可能性があるが、専門家の多くは慎重な姿勢で受け止めている。OpenAI の親子コントロール機能を利用して子供の ChatGPT アカウントを確認することが推奨されている。
This week OpenAI launched a version of ChatGPT exclusively designed for teenagers between the ages of 13 and 17, reports CTV, "saying this version came with stronger protections around content related to mentions of suicide, self-harm and romantic or sexual chats." [Tech analyst Carmi Levy says] "What it's doing is it's using cues, it's sort of watching how you're using the tool, and it's trying to guess your age." Levy said if ChatGPT thinks a person has lied about their age when they first signed up, it will automatically put them into the Teens mode for protection. "It includes those sort of two things: prevent you from having experiences that are age inappropriate, and also add features that are aligned with academics, so that makes it easier to study, makes it less likely for you to cheat on an assignment, provide resources that that that allow you to learn more effectively," he said. Levy reminded users that this is still an application and a web service, which means it's constantly collecting personal information about the users' activities on the device and using the data to estimate their age... In the event a user is talking about self-harm, this new version will block the conversation and suggest additional help or call emergency or mental health services, Levy explained. It would do the same with violent content, eating disorders, engaging in dangerous activities, as well as explicit, sexual or graphic content. "It's using AI again to sort of parse out that conversation: 'are we headed in a in a significant direction? If so, throw up that guardrail, stop it from happening, redirect.'" However, the tech analyst said a number of people who have attempted to bypass the guiderails for research have succeeded in doing so "with a little bit of prompting.... I wouldn't call it 100% safe. That's kind of the catch-22 of the entire AI industry." This will lead parents to think that their children are safer and reduce the oversight on their online activities, which Levy described as a "perverse impact" that is "problematic." "Parents should not assume that OpenAI has their kids' best interests at heart. They should also not assume that these technologies are perfect. They will miss certain things, and they will also engage in what we call false positives," he said. "An adult who's legitimately is in the platform might be tagged as a child because the AI simply got it wrong." OpenAI's blog post says the new mode was designed for "preserving the ability to learn, create, and explore." But CNN notes the move "comes as OpenAI faces a string of lawsuits alleging that inappropriate conversations with ChatGPT contributed to the harm or deaths of young people." [New tools] include nudges for teen users to take a break if they've been active for 90 minutes within a three-hour window. OpenAI is also adding options for teens or parents to set "Quiet Hours" when ChatGPT is unavailable or "Study Hours" where ChatGPT's study mode for learning will be on by default. The company also said it has improved protections to prevent ChatGPT from expressing personal feelings toward a user. And it's adding reminders that caution teens to think twice if they try to upload a private or sensitive image to the chatbot... Nearly a third of American teens use AI chatbots daily, a Pew Research Center study published in December found. ChatGPT was by far the most popular AI chatbot in the survey, with more than half of those teens reporting having used it. Engadget shared this observation from Josh Golin, the executive director of Fairplay, a non-profit advocating for policies to make the internet safer for children. "Most parents, overwhelmingly, do not avail themselves of [parental oversight] tools, in part because they are deliberately made hard to find and use." Golin's group wanted to see testing of the tools first to see whether they led to better outcomes for teenagers. "The way this was just announced feels more like a response aimed at public relations than actual deep thinking about what kind of support [teens] need." And Mashable got a similar quote from Robbie Torney, head of AI/digital assessments for Common Sense Media's Youth AI Safety Institute. OpenAI's teen experience makes important safety commitments, but "What we really need now is evidence that they work, and we need this evidence, including our testing and the testing of others, before anyone, including parents, puts real trust in ChatGPT for Teens." Importantly, Torney said parents shouldn't assume their child is using ChatGPT for Teens. While OpenAI uses age estimation to place users in the age-appropriate version of ChatGPT, it can still mistake a user as older. Parents can be sure their child is using the teen version by linking their ChatGPT account to their child's and implementing OpenAI's parental control features. If a teen has previously lied about their age — and plenty do — they may continue to access the adult version of ChatGPT... Torney said caregivers must enact parental controls to receive notifications from OpenAI should their teen discuss suicide, self-harm, or acts of violence in immediate or dangerous ways... An OpenAI spokesperson said every notification is reviewed by a trained human before it's sent. The company strives to review notifications in under one hour.

Slovakia Finds Russian Backdoor In Traffic Speed Cameras

🤖 AI Summary

Slovakian政府为了现代化交通监控而采购了速通摄像头,但发现了多个安全问题。国家安全部(NBU)发现这些设备存在短信激活的俄罗斯后门、缺乏认证且IP地址可直接访问实时视频流等问题。报告推测这些摄像头是由一家圣彼得堡公司Semicon生产的,并通过一家塞浦路斯的空壳公司以虚假认证购买。

最严重的是,这些摄像头包含了一组硬编码的俄罗斯电话号码列表,可用于打开后门。来自这些号码的短信可以提供shell和网络访问权限。安全启动功能无效,管理门户也可能被未授权者访问。

Slovakian Interior Ministry已经停用了已安装设置的摄像头,并将请独立审计员确认NBU的研究结果。推测其他东欧国家如克罗地亚可能也存在类似问题但尚未发现。
Slovakia acquired speed cameras to modernize its traffic control-- but there was a surprise. Tom's Hardware cites this story from the Risky Bulletin Newsletter: Unfortunately, the country's national security service, the NBU, has discovered that the cameras have multiple security issues. Firstly, they have SMS-activated Russian backdoors. Secondly, live camera feeds can be accessed by anyone with the device IP, no password necessary... [The cameras] are thought to be rebranded Russian CORDON PRO.M traffic cameras, produced by a St. Petersburg-based firm called Semicon... reportedly bought via a Cyprus-based shell company with fake certifications. Reports also suggest that pressure from the opposition political party in Slovakia led to the NBU investigations... Probably most seriously, in terms of national security, these cameras contain a hardcoded list of Russian phone numbers, which can be used to open a backdoor. An SMS from one of these numbers can open shell and network access... [T]he SecureBoot feature is ineffective, and the web management portal can be accessed, exposing live streams, by anyone with the camera IP. Cameras that have been installed and set up have since been deactivated by the Slovak Ministry of the Interior. Meanwhile, for due diligence, an independent auditor will be called in to confirm the NBU's findings. It is thought that Croatia, and some other countries in Eastern Europe, may have undiscovered issues with traffic control cameras of similar origin.

Stanford Economist Now Believes an AI Job Apocalypse Is Unlikely

🤖 AI Summary

エリック・ブレインドルフスンスタanford大学経済学教授は、人工知能(AI)による「雇用大虐殺」は起こらないと断言しています。彼はスタンフォードデジタル経済研究所の研究者たちとの共同研究で明らかにしました。ブレインドルフスン教授は、「ワシントンポスト」によれば、AIによる経済規模の雇用破壊はまだ見られていません。「低レベルの雇用は影響を受けるかもしれませんが、経験豊富な労働者如き先任コーダーへの需要は今後も高いままとなるでしょう」と予測しています。

さらに彼は、「Canaries in the Coal Mine? 人工知能による最近の雇用影響についての6つの事実」報告書を更新し、AIによる広範な雇用破壊は見られないと表明しました。ブレインドルフスン教授によると、今後10年以内にAIの能力が大幅に向上する一方で、失業率は歴史的な範囲内で安定すると予想しています。

彼はまた、ビジネスや経済には大きな影響があると指摘し、労働生産性が2%を超える成長を遂げる見込みであることも強調しました。さらに、AIを人間の補完手段として活用することで雇用を増やすことができると述べています。

一方で、低レベルの職種に深刻かつ持続的な影響がある可能性も認め、新規就労者の登録口が閉ざされてしまう可能性があることを警告しています。また、AIを使って若い従業員の教育を短縮する企業もあると指摘しました。
"There is still no sign of economy-wide job destruction," says economist Erik Brynjolfsson. Working with researchers at the Stanford Digital Economy Lab, Brynjolfsson has determined an AI "job apocalypse" is unlikely, reports the Washington Post, "even though it will likely impact entry-level jobs." And Brynjolfsson "predicts that demand for experienced workers such as senior coders will still be high even if AI takes on more routine knowledge and coding work in the future." Earlier this month, Brynjolfsson and his colleagues at the Stanford Digital Economy Lab updated their widely publicized report, "Canaries in the Coal Mine? Six Facts about the Recent Employment Effects of Artificial Intelligence," to reflect that they do not see widespread, economy-wide job displacement associated with AI... Brynjolfsson: What has moved on the upside is productivity. Nonfarm business productivity growth is running over 2 percent, the best sustained stretch since the late-1990s boom... The gains show up years after the investment, and they're starting to show up... By 2030, we will have enormously more capable AI, meaningfully faster productivity growth and an unemployment rate that looks unremarkable — somewhere in its historical range. That surprises people, but it's what the mechanism implies... [T]he technology is becoming much more powerful, and it's going to be even more powerful. Secondly, there are huge implications for business and the economy, including some increases in living standards, but also, potentially, job disruption. And then, thirdly, we must act now to address this gap. We can't just sit back and wait for the tsunami to hit us. And one of the things we can do is put in place institutions, policies and research to make the technology more complementary — using AI to complement people so it creates more jobs. A common misconception among business managers is AI, in order to be effective, has to reduce jobs. That's just not true. You can use AI to increase employment and productivity at the same time. It's kind of a win-win... Right now, tax policy is very skewed toward favoring capital versus labor — and, as a consequence, a lot of entrepreneurs and managers, they're basically being guided by the federal government to replace workers with machines. And I don't think that's necessarily what we'd like to have happen. From an economist's perspective, what you want to be doing is not mimicking and replacing things. You want to be extending and complementing — have humans do new things they never could have done before. He acknowledges "real, persistent and widening" effects on entry-level jobs, with a labor market "closing the on-ramp for people starting their careers... If companies don't hire people at the base of the pyramid, then they're not going to have those people later when they need them." One he points out that one company is instead using AI to speed up its training of young employees.

23 Years After SimCity 4's Release, 'Eternal Commuter' Bug Finally Fixed

著者: EditorDavid
2026年8月24日 00:34

🤖 AI Summary

SimCity 4 Network Addon Mod(NAM)は、現在で23年経った今でも機能し続けています。最新のアップデート50では、「永恒的な通勤ループ」バグがついに修正されました。

このバグは、ゲーム内のシミュレーションマップ境界線での路線計画アルゴリズムの問題によって引き起こされます。これにより、シミュレーターの「市民」が無駄な通勤ルートを追跡し続け、労働に就かずながら労働需要と交通状況が悪化します。

NAMは道路ネットワークとインフラストラクチャの大幅な改善も伴っており、新しいバージョンではDLLの強制的な導入によりコードベースがほぼ90%削減され、バグ発生のリスクも下がりました。

これらのことから、SimCity 4の歴史の中で最も長く続いた問題が解決されたと言えます。
"It began life just a year after SimCity 4's 2003 launch," writes the blog PCGamesN. "Now, over 20 years later, it's still going strong with the arrival of Network Addon Mod update 50." The SimCity 4 Network Addon Mod, or simply 'NAM' among the community, has long been a de facto recommendation to anyone looking to pick up the classic city builder. It's a comprehensive overhaul to the game's transportation and infrastructure networks that combines key fixes with a vast set of additional build pieces such as overpasses, intersections, on-ramps, roundabouts, and so on.... [Y]ou'll be able to place down elements adjacent to one another that might previously have needed a one-tile gap between them. Streets can be dragged diagonally, slope tolerances have been improved, and you can build tunnels with the street network. The new version also includes a fix for the 'Eternal Commuter Loop' bug, which might sound fairly innocuous if you're not deep in the weeds. In actuality, it's a 23-year-long frustration that has plagued modders ever since launch. Essentially, it's a problem with the regional pathfinding across city boundaries in certain layouts, causing your Sims to bounce from location to location in search of work without actually taking up a job in any of them. Your zone demand is ruined, traffic builds to unsustainable levels, and the economy falls to pieces before your very eyes. Until now, the only real solution was to simply avoid building layouts that gave your commuters the chance to loop between locations. Now, by blocking specific neighbor-to-neighbor routes while allowing the rest to run as normal, the problem has been resolved... Equally impressively, the mandatory implementation of the DLL has reduced the size of the NAM codebase "by almost 90% and by more than ten million lines, making it easier to maintain and reducing the chance of bugs." Thanks to long-time Slashdot reader Striek for sharing the news.
