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.。《日报》全媒体记者张宝程　　“村里现在的路既平坦又宽敞，村民们出行既安全又方便，找车运输苹果也不愁了，以后我们的苹果销量肯定更好，真的太感谢巡察组的同志们。”6月16日，绥中县沙河镇项家村徐家洼子屯村民刘恩勤拿着送给绥中县委巡察组工作人员的锦旗感激地说。

B | 　　修路一事还得从一次入村走访入户时说起。4月25日，绥中县委第三巡察组工作人员前往项家村入户走访，巡察组组长马闯发现该村部分道路破损严重，通往果园的山路坑坑洼洼，被雨水冲刷严重，车辆通行非常困难。

C | 随后，巡察组工作人员入户走访时发现村民对村屯道路反映问题强烈。　　“这条路破损严重，每次干农活，路上骑车都害怕，尤其下雨天道路泥泞不堪，路面积水严重，排水难。”一村民反映。　　“我们村苹果产量高，每年都为苹果的运输发愁，把这条路修好，能去了我们的一块心病”。另一位村民说。　　群众利益无小事，更何况这是村民出行、务农的必经之路。解决群众“急难愁盼”，就是巡察工作的重中之重。核实清楚情况后，巡察组将此问题反馈给相关部门。　　在巡察组的积极推动下，绥中县交通运输局同沙河镇党委结合项家村实际，邀请绥中瑞达公路工程有限公司进行专业分析研究，最终确定在原有的道路上将其扩宽硬化路面的方案。　　经过3天紧急施工，通往山上果园的路终于平坦了。此次共修4条村屯道路，道路总计长1250米，实际解决了村民出行和务农的安全问题，切实增强了群众的获得感幸福感安全感。　　　　巡察组充分发挥“边巡边改”的巡察监督成效的同时，让群众看到变化、见到实效，真正取信于民，切实让群众感受到巡察带来的新气象、新变化。
