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.

B | 整体来看，它让 Play 商店搜索变得有些类似 Google Lens 和“圈选即搜”，但同时结合了 Ask Play 的对话式 AI 能力。

C | 除了图片搜索之外，谷歌还有望在新版应用详情页中嵌入 Ask Play 界面，用户向下浏览页面时，可以看到 AI 生成的用户感兴趣的问题（例如应用隐私要求等），点击后即可获得具体详情。
