​Android M 预览版一周体验:重点为补强的更新

对不起各位读者,小编来迟了。这着重打磨和品质的 Android M 预览版好歹都推出了大半月,但因为借测机器和刷机都花了不少时间,所以就只能有这一周体验的文章。不过在这不算长的使用体用之下,已经发现了 Android M 也跟它推出宗旨相符,在 Android Lollipop 的的骨干之中,能感受到 M 所带来相当数量的补强。


虽然在 Android M 上有加入多个新功能,但一般使用者能够感受到,也就是在这体验文中会谈及的不算太多。丑话说前面,引发小编想要写这文章的 Now On Tap 在 Preview 版本仍未开放使用,所以只能引用一下主站动手玩中的要点和视频。另外的是因为测试机器是 Nexus 6 加上身处香港,所以原生指纹标准和新的 Android Play 平台都不能测试。

Search is everywhere 的界面

把 Android M 成功刷进并开机之后,首先的感觉是「咦?这跟 Lollipop 如出一辙吧!」,但其实在左下角已经有个微小但实在的改变:快捷键从拨号换成搜索了。这是 Android M 在界面上的最大改变,如何地方都有「搜索」。继 Android Lollipop 的桌面上把 Google Search 工具栏设为常设和加入 OK, Google 语音启动功能,在 Android M 中几乎所有原生界面都加入用于搜索的放大镜图标,方便使用者随时作应用程序内的搜索。

快速设定页几乎在每个系统的更新中都有对它作微调,而 Android M 的快速设定页上的 Wi-Fi 和蓝牙选项更是加入直接选择跟那个设备连接,这好用的功能在第三方品牌也不常见。另外,请勿打扰也改放在快速设定上面,因为在 Android M 音量控制部分变回一个纯粹控制手机音效的设定。

在 Android M 中变化最大的可看是其 App Drawer,因为它改用以英文字母或笔画作排序的垂直式清单,说实话,变不好用了。可是它把常用的四个应用程序钉选在 App Drawer 的顶部,算是这奇怪设计中的一个较正面的新功能。


虽说在 iOS 和国产手机 ROM 中已有类似功能,但权限管理是 Android M 仍然是个不可多得的重点,因为在使用者对隐私愈趋关注的今天,能知道并修改让应用程序的权限要求是很重要的。使用者可以从多个方式查询和编辑各应用程序要求存取的权限,最直接的当然是进入个别的应用程序信息页面查看,当中还有该应用程序的流量、电量消耗等信息,但这都是后话。另外在设定页中的应用程序更能按不同权限分类,例如可以找出所有要求存取手机位置的应用程序,使用者可以按需要自己开关。

问题是,不管是从 Google Play 还是安装 APK 都只能在应用程序安装到手机后才可以变更。如果能在安装前就能像国产手机般,先让使用者选择允许它存取什么权限,这样的安全性似乎更高(难道这是再下一版更新的功能)。


在以上的两个能在 Preview 版本 Android M 能用到,而且能亲身体验到的重点功能之外,还有着两个不好分类的东西。先是 Wi-Fi 热点的设定,(起码)在 Nexus 6 是能够选择 2.4GHz 和 5.0GHz 频段,让所分享的网路有更佳的接收能力。另外就是 Android M 的 Doze 节电能力,在这一周的非正式观察中,本来耗电就有点问题的 Nexus 6 在晚上以 LTE 待机时,居然能有 3 小时才耗 1% 电量的惊人记录。但平常使用却跟 Lollipop 时差不多,一天一至两充是需要的。


因为这次所试用的仍是预览版本,而且有不少重点功能都仍未开放使用,所以小编只能作个相对简单的小结。对比 Lollipop,Android M 更像在原本系统之上加入改进,因为在外观风格上并没有太大改变。但所加入的各位功能,都是 Android 对比其对手所缺乏的,像是权限管理和最重要的续航力。所以说,Android M 会是一个相当强力的补强,让 Android 系统能多添其他新功能。

2014年全球电子游戏产业总收入高达1000亿美金,几乎是电影行业的3倍。游戏《侠盗猎车手5》(Grand Theft Auto V)3天就赚了10亿美金;《我的世界》(Minecraft)也以25亿美金的价格卖给了微软;《Candy Crush》的开发者——King,2014年收获22.6亿美金;《部落冲突》(Clash of Clans)每位员的工收入几乎是谷歌员工的10倍;英雄联盟月收入达1270万美金。


每个人都可以在网上放东西并且很可能很快就会流行开来。在游戏世界也是如此,游戏名人靠传播他们的游戏视频来获取粉丝和财富。例如恐怖游戏与动作游戏达人PewDiePie拥有590万名Twitter粉丝,一跃成为世界名人。相比之下,其他名人的粉丝数则为:Tiger Woods450万;Beyonce1400万;Kobe Bryant660万;Rafa Nadal790万;Leonardo DiCaprio1280万。此外PewDiePie在Instagram上拥有420万关注者,YouTube频道订阅数超过3500万,排名第一。


如此高的游戏视频收视率就保证了大型游戏竞赛能吸引到众多观众。Dota2频道在Twitch上排名第三,火爆程度得以让其举办如此大型的比赛。同时,职业玩家通过流媒体与游戏爱好者进行交流也是很普遍的事,他们在常规游戏视频中展现自己的个性和游戏操作技能,还可以通过Twitch Chat、Reddit、Twitter等社交媒体与粉丝交流,这就好比罗纳尔多或梅西一边与队友踢着球,一边和你谈笑风生。





目前,手机游戏的火爆程度正在超越单机游戏,虽然传统的休闲类手游,如Angry Birds、Candy Crush、和Clash of Clans占据着市场,但是类似Dota2、StarCraft和Counter Strike这类竞技型、联网对战并更注重技巧的游戏也很有发展空间。现在的科技已经可以让这类游戏小型化,且操作更简单,这也是未来竞技类游戏发展的一个核心。

DTC就是Direct to consumer,大家熟知的23andMe就是这种业务的典型范例。相比一般研究,DTC类型中的样本提供者和研究人员并不分离。原文来自基云惠康创始人郝向稳。



23andMe是DTC业务的典型,DTC就是Direct to consumer啦。在一般的研究项目中,研究人员与提供样品的人员是分离的,科研人员拿到样品执行完研究计划后,通常是在学术期刊上发表论文,然后,然后和提供样品的人就没有关系了。




鉴于此,国家政府组织的基因测序计划也在如火如荼进行。英国的10万人基因组项目是世界上首个开展大规模人群全基因组测序的项目,这两年一直在稳步推进,上周,Genomics England发布Clinical Interpretation Partnership (GeCIP),确认了参与该计划基因组注释的人员,涉及了30个研究课题,包括2000名研究人员,希冀通过GeCIP项目,可以把基因组研究的成功直接惠及临床病人。

另外一项值得关注的进展是Oxford Nanopore首次发布了MinIon测序技术相关的价格:1000美元。用户可以得到USB大小测序仪MinIon MKI,包括三张测序芯片和两盒试剂的启动试剂盒、软件等。

在应用上,最近也是大出风头,从全长cDNA测序到埃博拉病毒检测;Oxford Nanopore更是放言,要把测序通量提高到40Gb(在USB大小测序仪上获得如此高的通量,加上超长的读长,确实令人充满了期待,但想想Oxford Nanopore一直以来的发展节奏,保持谨慎乐观!)

不满意 iPhone 的拍照表现?不如试试 DxO One



iPhone 作为手机拍照的标杆,虽然其各方面表现非常出色,但始终受限于体积等因素,无法与“大底”的数码相机相比。因此,像索尼这样的“黑科技”厂商便推出了 QX 系列外置式摄像头,还有仅在日本销售的奥林巴斯 Air。

此外,iPhone 还有一些扩展镜头,可以实现广角、鱼眼和微距等效果,但它必须要在摄像头或者手机背壳上使用可能并不美观的固定装置。

法国评测机构 DxO 实验室则另辟蹊径,推出了一款通过 iPhone 上 Lightning 接口的 DxO One 摄像头。对于 iPhone 上面这颗本来已经不错的 800 万像素摄像头,DxO 又是如何打算让你用上 DxO One 呢?

最小的 1 英寸传感器相机

与索尼 QX100/RX100 一样,DxO One 搭载了 2020 万像素的 1 英寸背照式传感器,但体积上相比外置式摄像头 QX100 要更有优势,约一个 Zippo 打火机的大小,重量 3.8 盎司(约 108g)。不过,外媒 CNET 对 DxO One 的评价是它太过于小巧,很容易会出现手指遮挡镜头的情况。

从图片上来看,连接在 iPhone 上面的 DxO One 更像是一台拥有大屏幕的 DV 摄像机。Lightning 接口的位置可以实现前后 60 度旋转,使用效果就相当于相机上面的可折叠屏幕,实现更方便的多角度取景。

镜头方面,DxO One 采用了一颗 11.9mm 焦距的六片非球面镜头(等效焦距 32mm),与 iPhone 上面的摄像头焦距差不多,此外还支持 3 倍数码变焦,和最近对焦距离 20 厘米。不过,DxO One 则拥有 f/1.8 的最大光圈和 f/11 最小光圈,在 1 英寸的“大底”下,f/1.8 的浅景深表现估计会比 iPhone 的摄像头出色不少。

为了能够实现更光亮环境下使用大光圈镜头,DxO One 的快门速度最高可以达到 1/8000 秒,而长曝光模式则可以最长达到 15 秒的快门。对于单反来说,1/8000 的快门在入门级 APS-C 和入门级全画幅上都没有配备。

原生 ISO 100-12800,扩展最高可达 51200,在相机中的配置并不算高,但对于手机来说已经远远超越。只是如此高的 ISO 表现如何,则有待真机体验之后才可下定论。

除了能够拍照之外,DxO One 还支持具备电子防抖的最高 1080P/30fps 的视频录制。

除了支持 RAW,还有 SuperRAW

iOS 良好的应用生态,造就出不少优秀的摄影类应用,让用户深深依赖于图片后期。而图片后期让人最纠结的问题就是本身已经有损压缩的 JPEG 图片,经过处理后细节的丢失可能更大。为了寻求更大的后期空间,不少用户选择了原始数据的 RAW 格式来储存照片。

RAW 格式可能大家已经非常熟悉,目前也有不少手机已经支持 RAW 格式拍摄,但不仅作为硬件厂商还是一个软件厂商的 DxO,在 DxO One 上增加了 SuperRAW 格式的拍摄。

SuperRAW 也不算是一个非常神秘强大的功能,它只不过是同时拍摄 4 张连续的原始图像,然后进行堆栈式处理。在低光的环境下,可以减少照片中的噪点。与 HDR 不同,SuperRAW 拍摄的是相同曝光的原始图像,而 HDR 是合并不同曝光的图像来实现广泛的宽容度,所以 SuperRAW 的唯一特点就是在低光环境下,减少照片中的噪点。


DxO One 上方是一个二级快门按键,背面是一个 OLED 触摸屏,可以显示相机的重要信息,同时还可以切换相机模式。触摸屏下方是 Micro USB 接口以及 Micro SD 内存卡。内置电池充满电量之后,可以拍摄大约 150-180 张照片。在 iPhone 上安装 DxO One 的配套应用就能够使用相机。



之前在体验索尼 QX100 的时候,虽然 1 英寸传感器搭配卡尔蔡司的镜头,让画质和色彩都非常讨喜人,但因为数据通过 Wi-Fi 传输,如果遇到无线网络环境比较复杂的情况,就会出现传输速度慢,实时取景延迟时间长等问题,影响了 QX100 的体验。

而如广角、鱼眼和微距的扩展镜头使用在 iPhone 摄像头上,先不说搭配的保护套美观与否,在本身已经非常局限的手机拍摄能力上,再进一步损失画质,显然有些得不偿失。

在 Lightning 接口上衍生出来的周边配件很多,然而却很少出现在 Lightning 接口上的相机。DxO One 的设计思路实际上是准而狠的,无需使用可能不太美观的保护套,同时也不需要通过无线传输,在使用体验上可能要比索尼 QX100 和扩展镜头更有优势。

由于没有体验过真机,对于画质如何还不好定夺,但要说 DxO One 的缺点,可能不得不提它的售价,599 美元的价格有些让人望而却步。

Google 图像识别 AI 眼中的世界是怎样的?

Google 在 2015 I/O 大会上推出的 Google Photos 不仅仅是一个相册,它可以将相册中同一个人物的照片整合在一起,比如回顾一个婴儿从小到大的成长轨迹。通过人工智能的长期学习,它甚至可以自动判断对你重要的时刻、重要的人、和重要的事物。

在其中起到关键作用的是 Google 的图片识别 AI 。它通过学习大量的图片、调整算法来提高识别的精确度。

但是工程师们要如何知道 AI 对图片识别的准确性呢?

通过一个被称为 Inceptionism 的项目,Google 工程师潜入了 AI 的 “梦境”。他们先输入一张图片,让它识别图片中关键的部分;再让 AI 输出一张图片,表达它对图片的理解。


Google 的图片识别 AI 具有 30 层神经网络,每一层对应着不同的抽象程度,比如最低层次能识别光线、色彩,下一层次能识别图片的边缘等等。这样一层层的“训练”需要大量的数据。每一层都能提取出更高层次的细节,而最后一层会决定 AI 对图片的理解。

比如你想知道输入怎样的图片会让 AI 认为是“香蕉”,可以从一张满是噪点的图片开始,然后慢慢调整,直到它输出你想让它识别的事物。


在测试中,当试图询问哑铃是什么时,Google AI 输出了带手臂的哑铃,在输入学习的图片库中,哑铃都是和手臂一起出现的。那么提高认识精确度的办法就是,在训练学习中多输入一些哑铃单独出现的图片。




Google 还专门为这些图片建了一个相册。有的如同超现实主义的艺术作品,有的则十分惊悚。这些图片至少能够表明,AI 眼中的世界显然与人类还有很大的差距。


“这是我见过最恐怖的东西。如果 AI 眼中的世界是我们永远都不可能看到的,那么我们要怎么回应它们的行为?”




Docker与CoreOS 联合推出Open Container Project,要实现容器技术的标准化

在旧金山举行的2015 DockerCon大会上传出了一则重磅消息,容器技术的当红炸子鸡Docker与基于Linux内核的轻量级操作系统CoreOS联合推出了开放容器项目Open Container Project,目标是实现容器镜像格式与运行时的标准化。这很有可能实现,因为这两家小公司已经几乎把所有的大公司都吸引到了项目当中,包括微软、IBM、Google、英特尔、Amazon、HP、华为、思科、EMC等。



在分工上,Docker将为项目贡献其容器格式、运行时代码并提供规范。而Amazon Web Services、Apcera、思科、CoreOS、Docker、EMC、富士通、高盛、Google、HP、华为、IBM、英特尔、Joyent、Linux Foundation、Mesosphere、微软、Pivotal、Rancher Labs、Red Hat以及VMware将围绕着容器格式和运行时建立标准。这个项目可谓汇聚了业界的中坚力量来共襄大业。

历史已经表明,标准对于推动产业发展具备极高的重要性。同时,需要制定标准也代表了技术的蓬勃发展已经到了需要规范的地步。除了容器技术以外,我们还可以看到其他的标准化努力,如致力于制定软件定义网络(SDN)规范的 OpenDaylight Project,制定物联网标准的 Allseen Alliance等。一旦这些标准制定取得成果,也就意味着相关技术即将走向成熟和大规模应用了。
