二、SpaceX“猎鹰9号”火箭发射成功 携带两颗互联网卫星

太空探索技术公司SpaceX刚刚成功地发射了一枚“猎鹰9号”火箭，将其两颗互联网实验卫星送入轨道。
在此之前，这枚“猎鹰9号”火箭已经两次推迟发射。原计划于2月17日发射，后来又分别推迟到2月21日和2月22日。今日，这枚火箭终于顺利升空。
猎鹰9号”火箭此次搭载的这两颗实验卫星是SpaceX CEO埃隆·马斯克（Elon Musk，同时也是特斯拉CEO）提供互联网卫星计划的一部分。
马斯克计划利用5年的时间将4425颗卫星送入近地轨道（LEO），从而为全球消费者提供低廉、快速的宽带互联网服务。另外，马斯克还考虑将来在火星上部署同样的卫星网络，以便于将来人类殖民火星。
除了这两颗互联网实验卫星，刚刚发射的这枚“猎鹰9号”火箭还搭载了西班牙客户Hisdesat公司的PAZ雷达观测卫星。
另据新华社报道，一份向美国电信业监管机构联邦通信委员会（FCC）提交的文件显示，太空探索技术公司将向太空发射约1.2万颗卫星，从太空“直接向美国或全球”提供高速互联网接入服务。而“猎鹰9”火箭22日送入太空的两颗卫星——Microsat-2a和Microsat-2b正是这一项目的首批测试卫星。
依照计划，将有4425颗卫星部署在地球上方1150公里至1325公里处的近地轨道，传输波段介于Ku与Ka之间；另外7518颗卫星将部署在地球上方335公里至346公里间的极低地球轨道，以V波段传输数据。
这些小型卫星的发射将持续至2024年，届时卫星互联网系统将满负荷运行。这些小型卫星的长、宽、高分别为4米、1.8米和1.2米，每颗卫星如一辆轿车大小，在不包括太阳能电池板的情况下重386公斤。
三、陌陌收购探探，陌生人社交迎来终章？

近日移动社交公司陌陌宣布，陌陌将以向探探发行股票及现金的方式收购探探100%股权，对价包括约265万股的ADS及约6亿美元现金。满足惯例成交条件之后，此收购案预计在2018年第二季度完成。交易完成后，探探原团队将继续独立运营产品和品牌。华兴资本作为这次交易的财务顾问。
国内的互联网企业终究还是会走上一条极为惊人的老路子。行业老大吞并一切，垄断必然要形成。就像滴滴收购快的和优步中国、58同城并购赶集、美团与大众点评联手……类似的例子不胜枚举。而如今陌陌收购探探，则是国内陌生人社交领域的老大全资收购了老二。
从近7亿美元的收购资金上看，陌陌其实还是不亏的，毕竟探探此前也完成了多轮天价融资。500万美元的A轮融资、1300万美元的B轮融资、3200万美元的C轮融资、7000万美元的D轮融资等，总融资达到1亿多美元。而由此衍生出的高估值，据悉已经达到3亿多美元。鉴于收购探探后有可能成为陌陌继续成长的强劲推动力，7亿美元算是“正常价”。
作为陌生人社交领域的老大，在将“陌生人社交”做到顶峰之后，陌陌就开始强化在其他领域的投入和运营。如，游戏、直播、短视频等成为陌陌营收和利润的主要来源，帮助陌陌迅速打响翻身之战。不过，依靠陌生人社交起家的陌陌还是不会忽视高质量“陌生人社交”的力量。
而就探探来看，在其发展过程中始终保持着审慎、克制的态度。据了解，探探在产品规划之初就明确女性为重，且把男女用户比例固定在6：4——这也是中国现阶段人口的男女比例。此外，探探用户群更加年轻，是国内95后年轻单身人群拓展社交关系的重量级平台。无论是较多的女性用户，还是更加年轻的扎堆群体等，对于急需新鲜血液融入的陌陌而言，都有着极强的诱惑力。
社交平台说到底有着极为明显的“人气效应”，用的人越来越多，才会更吸引用户进入，由此让社交关系链不断扩大。进而反哺至社交平台本身，让其迅速壮大。专注于陌生人社交的陌陌和探探，会形成男性、女性用户的互补。而在用户数激增之后，陌陌的直播、游戏、短视频等业务也能够借此向前狂飙突进，进而形成更好的内容生态。
最终，强强联手是让陌生人社交领域再也不会有新入局者，陌陌真正成为行业NO.1。这样的结局究竟是好是坏，还有待时间去进行验证。
四、《舌尖上的中国3》口碑崩盘
时间：2.22
来源：凤凰、网易、新浪等
《舌尖上的中国3》于2月19日首播之后，就被观众们骂惨，豆瓣评分一跌再跌，到2月23日，只剩下5.2分。《舌尖3》口碑坍塌，直接拖垮了国内最火的纪录片系列，将《舌尖上的中国》这档引起广泛关注的美食类纪录片拉下神坛。
要知道，2012年《舌尖上的中国》第一季一经推出，就火遍网络。
《舌尖上的中国》制作精良，不但以令人垂涎欲滴的中华美食征服了广大吃货同胞，而且也传播了源远流长的中华饮食文化，让观众们受益匪浅。因此，获得广大国人追捧，也成为中国最火的纪录片。《舌尖上的中国》第一季也以优良口碑，获得9.3分的大神级豆瓣评分。
时隔两年之后，中国中央电视台再推出《舌尖上的中国》第二季，继续探讨国人与美食的关系。为我们观众呈上了300余种美食，绝对能让观众们大饱眼福。
第二季主打人文牌，刻意突出候鸟打工族、留守儿童、应试教育、空巢老人等社会热点，通过美食，侧重传递了“乡愁与怀旧”的情绪。但由于采用分集导演拍摄的模式，因为各分集导演水平不一，导致各集之间水准参差不齐，显得不伦不类。
《舌尖上上的中国》第二季口碑也就有所下降，不过也获得了8.4分的超高豆瓣评分。
但是，今年《舌尖上的中国》第三季播出后，豆瓣评分跌到只剩5.2分，估计还有下探空间。真是让人无法相信。
《舌尖上的中国3》之所以口碑坍塌，被观众们差评最多的就是：拍摄不专业，错漏百出，与前作相比，简直大失水准；广告植入过多，有蒙骗观众的嫌疑；偏离人与食物的主题，连中药口红也堂而皇之的登场。总之，在《舌尖》粉们看来，《舌尖3》简直就是槽点满满的败笔之作。
那到底是什么原因，导致《舌尖3》大失水准，口碑坍塌了呢？
有细心的网友指出：老铁们！注意了，《舌尖3》导演换人啦！
《舌尖上的中国》第一季的导演是陈晓卿、任长箴、程工；第二季的总导演是陈晓卿，分集导演是李勇、陈磊、胡博、邓洁、费佑明、刘硕、陈硕、丁正；而第三季的导演是刘鸿彦、沙洛、骆永红、黄鹤、张木、陈硕仪、王申。看来，《舌尖3》也是采用分集导演拍摄的模式，由刘鸿彦担任总导演。
导演是一部影片的灵魂。
《舌尖上的中国》第一、二季口碑良好，总导演陈晓卿总揽全局，功不可没。第二季采用分集导演拍摄模式后，虽然有总导演陈晓卿把关，但还是没法保证各分集不失水准，口碑自然就有所下降。第三季将所有导演换人，没有陈晓卿啥事了。这是否是《舌尖3》口碑坍塌的一大原因呢？
每个导演都有自己的拍摄理念，《舌尖3》将总导演换成刘鸿彦，自然也就拍不出前面两季的味道来，不被观众们认可也是正常不过。

春节前夕，火爆的直播答题迎来监管“大棒”，直播答题市场一夜之间进入集体性“哑火”。
不过近日，答题战场迎来了转机。今日，百度旗下好看视频推出的直播答题活动《极速挑战》目前已经获得北京市新闻出版广电局审核批复，成为监管出台之后唯一正式回归的直播答题栏目。
2月14日，曾经风光无限、吸粉无数的各大直播答题平台纷纷踩下急刹车。而从他们此前公布的宣传海报来看，“急刹车”显然不在意料之中。2月13日，百万英雄官微还曾发出预告称，2月16日大年初一晚8点将举行《百万英雄》小米手机专场，12题瓜分500万。
这场“集体告别”只因当天监管措施的出台。2月14日，国家新闻出版广电总局网络视听节目管理司联合北京新闻出版广电局，约谈了17家开办网络直播答题活动的视听网站代表，严肃指出当前网络直播答题活动中出现的导向偏差和违规问题，就进一步规范网络直播答题活动提出工作要求。
广电总局在《国家新闻出版广电总局要求加强网络直播答题节目管理》的通知中，要求各级管理部门采取有效措施，规范网络直播答题节目管理，并提出五点意见。其中包括不得宣扬拜金主义和奢靡之风、开展网络直播答题节目的平台必须具有法定网络视听节目直播资质、直播答题节目主持人应当具备广播电视节目主持人相应的条件、网络直播答题活动不得过度营销和过度炒作等内容。
此前，直播答题曾因BUG不断、内容存在漏洞、过度营销、外挂作弊手段丛生而饱受网友诟病。
百度好看视频《极速挑战》活动制作方负责人表示，全新的直播问答栏目将于2月24日晚上19：30正式开启第一场。回归后的《极速挑战》，将继续为广大用户带来健康有趣的知识，并将更加注重直播内容的质量，为营造良好的网络娱乐环境助力。
此前，中国政法大学知识产权研究中心特约研究员李俊慧撰文指出，直播答题要想延长节目生命周期，需要从内容细分、人群细分角度，通过设置各类专场，实现知识性与趣味性、专业性与广告合作的适度平衡，让更多人的参与进来，在确保商业价值实现的前提下，传播更具正面效应或价值的内容或信息。

今年贺岁档上映的电影，有《唐人街探案2》《西游记女儿国》《熊出没·变形记》《红海行动》《捉妖记2》《祖宗十九代》6部新片上映，成为今年春节档的票房主力军。
在春节假期7天内，《唐人街探案2》《捉妖记2》《红海行动》三部作品分别以18.94亿、17.03亿、11.97亿票房成为今年春节档电影市场前三甲，包揽了8成以上的票房份额，《西游记女儿国》《熊出没·变形记》分别以4.35亿、3.65亿位列第四、五位。
国外事记
一、Facebook says it’s clarifying its ad metrics
时间：2.22
来源：TechCrunch
Facebook is looking to clean up and clarify the way advertisers measure their campaign performance.
Over the past couple of years, the company has had to acknowledge multiple mistakes in its ad metrics. Last fall, researchers even pointed out that Facebook’s purported reach was greater than the US Census population in every state.
So making these kinds of tweaks (and taking other steps to increase transparency) could help restore advertisers’ confidence in the company’s numbers.
Facebook laid out the changes in a blog post, and also at a press event this morning, where Vice President of Marketing Science Brad Smallwood was joined by Edward Gaffney, director of Implementation Research at ad agency GroupM. (Gaffney is part of Facebook’s Measurement Council.)
The first change comes in the way these metrics will be labelled. Facebook will now explicitly point out when an ad metric is an estimate, in development or both.
Gaffney said that advertisers are used to working with estimates, but he recalled that even in the Measurement Council there was some uncertainty around which numbers were estimated versus directly measured. So this kind of clarity is needed “to understand that an estimate is just that — it’s better than a guess, but it is not the absolute truth.”
Meanwhile, Smallwood said that it’s natural for Facebook to experiment with the most effective ways to present its data. By labeling a measurement as in development, the company is telling advertisers to expect those measurements to change. (As Gaffney put it: “Don’t build a complex model around that.”)
Some of the metrics might eventually disappear entirely if they’re not helpful to advertisers. In fact, Smallwood said Facebook plans to remove 20 of them in July because they were judged redundant, outdated, not actionable or infrequently used.
For example, he said the social reach metric (which shows how often people saw an ad accompanied with context like a comment from their friend) turned out to be not that different from a standard reach metric, and advertisers didn’t know how to use the data to improve their campaigns. So it’s getting cut.
Lastly, Smallwood said Facebook will be launching a new initiative called Measure What Matters, combining in-person events, online events and online content to help advertisers understand more about how to measure and improve their campaigns.
二、Privacy and human rights advocates are worried about Apple's imminent iCloud move in China
时间：2.25
来源：Mashable
Apple is preparing for a big change at the end of the month: Henceforth, iCloud data belonging to users based in China will have to be stored there, in the company's new Chinese data center.
That means text message, emails, and other data stored in the cloud will be physically housed on Chinese soil. Importantly, it also means that the cryptographic keys required to unlock an iCloud account will live in China as well.
SEE ALSO: Here's what we think about Apple's HomePod
Previously, as Reuters points out, those keys had been stored in the United States. Whenever Chinese authorities have sought access to a user's account in the past for one reason or another, they'd have to go through the processes set forth in the U.S. legal system.
Moving the keys to a data center in China means that authorities can seek access to iCloud accounts using the local legal system instead. This is a worry to human rights and privacy advocates, who fear what the country's looser privacy restrictions and the broad powers held by local authorities might mean.
"Even very early in a criminal investigation, police have broad powers to collect evidence," Jeremy Daum, an attorney and research fellow based in Beijing, told Reuters. "[They are] authorized by internal police procedures rather than independent court review, and the public has an obligation to cooperate."
China's data privacy laws also offer little protection when the authorities in question are investigating certain criminal offenses, including some that many countries would define as political suppression.
Two Chinese citizens were jailed as dissidents in 2002 for distributing pro-democracy writings and other materials. It was later discovered that the damning evidence had been provided to the Chinese government by Yahoo, prompting harsh criticism. The tech company later apologized and settled a lawsuit brought by the families of Chinese activists.
While plenty has changed in China since the events of 2002 — that was more than a decade before the country's longtime ban on video game consoles finally lifted, for example — concerns remain.
Some have criticized Apple's decision, but the company contends it tried to keep this from happening.
"While we advocated against iCloud being subject to these laws, we were ultimately unsuccessful," a statement provided to Reuters reads. Apple claims that moving iCloud data and encryption keys to China is preferable to shutting down iCloud services there completely, a move that the company says would add to the risk of user security and privacy being compromised.
Apple maintains that it alone controls the encryption keys, regardless of the nation in which they're based. Even its Chinese partner — the state-owned Guizhou, which helped to get the data center established — doesn't have access.
Of course, that's exactly what a company concerned with its own interests would say in a situation like this. Apple's partnership with Guizhou is a necessity; without it, the U.S. company wouldn't be able to store data in China under the new rules. That, in turn, could cut off Apple's access to the large Chinese market of more than 1 billion potential customers.
三、Trump Uses Facebook Exec Tweet To Call Media "Fake News"

President Trump approvingly passed along comments from Facebook ads Vice President Rob Goldman on Saturday, using Goldman's remarks about the Kremlin-linked chaos campaign on Facebook to call reporters covering the situation, the "Fake News Media."
Goldman, reflecting on special counsel Robert Mueller's indictment of 13 individuals linked to a Russian troll farm, took the opportunity to call out reporters covering the developments.
"Most of the coverage of Russian meddling involves their attempt to effect [sic] the outcome of the 2016 US election. I have seen all of the Russian ads and I can say very definitively that swaying the election was *NOT* the main goal," Goldman said at the start of a two-day tweetstorm, spanning Friday and Saturday.
"The majority of the Russian ad spend happened AFTER the election. We shared that fact, but very few outlets have covered it because it doesn’t align with the main media narrative of Tump and the election," Goldman added.
Trump seized on these comments, using them to continue his attempt to discredit the news media's efforts to report on a Kremlin-linked campaign to influence the 2016 US presidential election and sow discord in its aftermath.
"The Fake News Media never fails. Hard to ignore this fact from the Vice President of Facebook Ads, Rob Goldman!" Trump said in one tweet quote tweeting Goldman's remarks.

"'I have seen all of the Russian ads and I can say very definitively that swaying the election was *NOT* the main goal.' Rob Goldman Vice President of Facebook Ads," Trump wrote in a subsequent tweet.
On the same day Goldman sought to blame the media, Facebook and Instagram were mentioned 41 times in Mueller's indictment, far outpacing Twitter, YouTube, and Paypal.
A spokesperson for Sen. Mark Warner, vice chair of the Senate Intelligence Committee, said on Twitter that focusing on the ad spend Goldman referenced is "missing big picture."
Asked to comment, a Facebook spokesperson pointed BuzzFeed News to a subsequent tweet from Goldman where the Facebook VP said, "I am only speaking here about the Russian behavior on Facebook. That is the only aspect that I observed directly."
