hmd视频建议：诺基亚9 pureview和其他新飞机可能在mwc 2019中提供_我的网站

一 | 1月13日，HMD还没有公布诺基亚9 pureview等新产品的发布日期，有点不舒服。

二 |     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.。

三 | 早些时候，有消息称，新的重型设备诺基亚9 pureview将于2019年1月底面世。但是今天，HMD的CPO Juho Sarvikas在Instagram上发布了一段短片，回顾了诺基亚在2018年MWC上的精彩时刻。该视频包含显示诺基亚8110 4G、诺基亚1、诺基亚6.1（第二代诺基亚6）、诺基亚7 Plus和诺基亚8 Sirocco旗舰产品的HMD场景。值得注意的是，萨维卡在这篇文章的标签上写了“酷新闻塔夫”，这似乎暗示了一些东西。NPU推测HMD将于2019年在MWC上推出诺基亚9 PureView和诺基亚6.2（诺基亚6的第三代）。根据之前公开的宣传视频和其他信息，诺基亚9 PureView将配备一个后置蔡司5相机，它可以带来比普通智能手机10倍的光，以及强大的HDR功能。诺基亚9 PureView将配备5.99英寸的2K屏幕，支持HDR 10，手机在屏幕下支持指纹识别技术。（对于无法观看视频的移动客户端用户，请单击此处查看）。
