Janet Jackson's 1989 Hit 'Rhythm Nation' May Literally Crash Laptops, Microsoft Says_我的网站

A |     The 1989 song "Rhythm Nation" by Janet Jackson has a funky/new jack swing-ish beat that encourages dancing, but it also has a special frequency that can cause some laptops, fortunately from the bygone era of Windows XP, to crash, Microsoft developer Raymond Chen said.,Chen, the chief software engineer at Microsoft, reported the problem on his blog The Old New Thing this week. He claimed that the song's frequency coincided with the laptop hard drive's resonant frequency, which is an object's inherent frequency.,The way a glass breaks when exposed to certain noises is similar to how a laptop crashes, Chen asserted, as the sound from the source sends an unseen vibration through the air and onto the glass.,"A colleague of mine shared a story from Windows XP product support. A major computer manufacturer discovered that playing the music video for Janet Jackson's 'Rhythm Nation' would crash certain models of laptops," Chen wrote. "I would not have wanted to be in the laboratory that they must have set up to investigate this problem. Not an artistic judgment.",According to Chen, the manufacturer discovered that Jackson's song also crashed laptops built by its rivals.,"Playing the music video on one laptop caused a laptop sitting nearby to crash, even though that other laptop wasn't playing the video," he said. "It turns out that the song contained one of the natural resonant frequencies for the model of 5400 rpm laptop hard drives that they and other manufacturers used.",Then, manufacturers included a "custom filter in the audio pipeline that detected and removed the offending frequencies during audio playback," and this fixed the problem. Chen added that they likely attached a digital version of a "Do Not Remove" sticker on that audio filter.,However, he expressed some concern that, after adding the workaround many years ago, nobody would remember its purpose.,"Hopefully, their laptops are not still carrying this audio filter to protect against damage to a model of hard drive they are no longer using," Chen concluded.,Chen did not say what kind of sounds caused such a resonance. But that apparently does not matter now, given the transition of laptops and desktop computers to SSDs.,In addition, Chen attached to the post an old educational video from the data center, which demonstrates the effect of sound wave vibrations, namely human screams, on the operation of hard drives in a rack.,By and large, resonance is a physical phenomenon in which the frequency of one object's sound waves and those of another object coincide. This may result in a sharp rise in amplitude. This is why some bridges have previously collapsed.。    　　8月25日，外交部发言人林剑主持例行记者会。

B | 有记者提问，2026年世界机器人大会在北京成功举行，第二届世界人形机器人运动会也在国家速滑馆“冰丝带”开赛，中国制造的机器人分别打破了人类百米跑和男子跳高等多项世界纪录，也引发全球热议。但也有评论认为，相关产业落地和商业化前景并不明朗，部分国家对中国高科技产业采取防范和限制措施，也会让中国同世界分享机遇的承诺面临阻力。发言人对此有何评论？　　林剑表示，我们也看到了不少这方面的消息。除了赛场比拼，更值得关注的是人形机器人正加速从实验室走向产业化，不仅能在工厂里分拣包裹、组装零件，也能在社区中辅助养老护理、早教育儿，还能完成打乒乓球、折叠衣物等精细动作。这背后展现出整机厂商、核心零部件企业、算法研发团队的协同攻坚，更离不开中国长期稳定的政策支持，持续强化的创新驱动，丰富多元的应用场景。
