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.。    Months after missing the first primary debate stage -- which prompted a complaint with the Republican National Committee -- businessman Perry Johnson has decided to suspend his short-lived presidential campaign, he announced Friday."With no opportunity to share my vision on the debate stage, I have decided at this time, suspending my campaign is the right thing to do," Johnson said in a statement.He has not withdrawn completely and will remain on the ballot in early states like New Hampshire where he attended the NH GOP's First in the Nation Leadership Summit just days ago.Johnson is the third candidate to drop out of the presidential race, after Rep. Will Hurd and Miami Mayor Francis Suarez halted their campaigns earlier this year.Johnson took multiple swipes at the RNC amid a potential legal battle he claimed he would wage against the committee after failing to meet the polling criteria to make the first debate stage.He subsequently filed an FEC complaint against the RNC and Fox News, which hosted the first debate, accusing them of "a collusive effort to cherry-pick participants."Johnson's campaign told ABC News "he's not ruled anything out" when asked whether he would move forward with the complaints now that he has suspended his campaign."I've said it before and I'll say it again: the people should decide the next president of the United States, not the head of the RNC and her cronies," Johnson said in his statement.An author and a wealthy businessman, Johnson funded almost the entirely of his presidential campaign with his own money, loaning $12 million to his campaign and contributing more than $1.5 million worth of flights for his campaign through his private plane, his campaign disclosure reports show.。
