Chrome OS – A Top Priority For Google

0

google-founders1

There have always been questions in the Chromebook forums and from readers of this blog; about how much Google believes in Chrome OS. The proverbial words; ‘Google Buzz’ are often flung like feaces from hand during such discussions. Indeed we have heard the arguement that Buzz was a failure because Google never put it’s full weight behind it. But are such arguements grounded and can we relate them to Chrome OS? I say no.

Google: Chrome’s Purpose is Search Dominance

0

During their Q1 conference call, Google’s executives discussed their Chrome strategy, which provided plenty of answers, if you were wondering why Google is putting so much focus on a product that is given away for free.

Google hopes that Chrome tightly aligns with its search strategy and locks Chrome users into using its search engine.  

Referring to the Chrome business strategy, chief financial officer Patrick Pichette said the Chrome browser itself uses the Omnibox to shorten the way to Google search while still providing Google with search advertising revenues. It gets more interesting with Chrome OS, however: Google considers everyone who uses Chrome as a "locked in" Google user. Since Chrome is essentially the operating system on a Chrome OS device, Google is using the browser to simply monopolize the search engine market.

Chrome OS will not create a walled garden, says Google

0

chromestore-728-75

Google has insisted that Chrome OS will not give rise to another walled garden, insisting that the apps store for the next-generation cloud operating system will not be a closed system.

Google’s fondness for openness has been brought into question of late, with the decision to hold back the tablet friendly Android Honeycomb from the public domain, and decisions over video codecs causing rumblings.

However, the search giant insisted to TechRadar that the Chrome Web Store would not be locked down in the same way as some of its rivals – including the notably tightly controlled Apple App Store.

尽管是一个基于浏览器的操作系统,Chrome OS依然是有屏保的。其实你也不必等上老半天才能欣赏到Cr-48螃蟹本上的屏保,只要访问 file:///usr/share/chromeos-assets/screensavers/screensaver.htm(没Cr-48本本别瞎点这个链接,没用的……) 这个地址,即可看到了(如上图),恩这显然是一个HTML 5写的动态动画。

Chrome OS CR-48 螃蟹本进入开发模式并 root 视频教程

0

screen-capture21-550x324

今天The Chrome Source给我们带来了全程视频,预感到将来会拿到螃蟹本的同学不妨关注一下,其实非常简单:

  1. 关闭CR-48
  2. 翻个个儿
  3. 拆下电池
  4. 在电池触电旁边有一个黑色胶布(上图),毫不留情的扯下
  5. 胶布下就是一个白色的开关,把它从靠近电池触点的一方向远离触点的方向拨过去,如果你手太胖,找只笔
  6. 放回电池,启动电脑。你会看到一个提示,按Ctrl+D跳过(不跳过也可以等它一会自动哔的一声),进入开发模式
  7. CR-48会刷新系统,用开发模式的镜像系统替代以前的系统,这需要等待5-6分钟
  8. 重新进行四步初始设置
  9. 登录后,用Ctrl+Alt+T即可进入到终端
  10. 此时你可以以user权限进入shell了,输入help可查看所有可用命令
  11. 输入“shell”后就可以开始用你熟悉的 bash 了,你当前身份将是名为 chronos 的用户
  12. 输入“sudo su”
  13. root成功!

CR-48 Chrome OS 螃蟹本拆解及具体硬件参数

0

chrome-cr-48-550x339

Brad Caris在拿到Chrome OS CR-48螃蟹本之后,对其进行了拆解,看到了各个硬件的具体参数,跟大家分享如下:

  • 处理器: Intel Atom Processor N455 1.66GHz 512K Cache
  • 芯片组: Intel CG82NM10 PCH
  • 主板: Tripod Motherboard MARIO – 6050A240910 – MB – A03
  • 内存: Hynix 2GB DDR3 1Rx8 PC3 – 10600S Ram
  • 只读内存: ITE IT8500E Flash ROMSSD
  • 硬盘: SanDisk sdsa4dh-016G 16GB SATA SSD
  • 无线: AzureWave 802.11 a/b/g/n PCI-E Half MiniCard
  • 3g 适配器: Qualcomm Gobi2000 PCI Express Mini Card
  • 蓝牙: Atheros AR5BBU12 Bluetooth V2.1 EDR

明年中期上市的三星和Acer Chrome OS笔记本想必也大概会是这个硬件配置,顶多就是CPU速度再高点,硬盘再大点。谁知道这枚SSD的读写速度是多少?

另外,iFixit的“芯片级”专业拆解怎么还不拿CR-48动手啊?等不及了都~~

教你如何使用 Chrome OS 螃蟹本 CR-48 的蓝牙功能

0

在 CR-48 拆解中,我们已经发现其内置了一块支持 2.1 EDR 的 Atheros AR5BBU12 蓝牙芯片,但是很显然我们在自带的 Chrome OS 系统中无法将其利用起来,要使用这个东西还是有些技巧的:

  1. 进入开发者模式。
  2. 按 Ctrl+Alt+T 打开 terminal
  3. 输入 shell 回车,进入 bash 环境
  4. 将你的蓝牙设备设置为可发现模式
  5. 在 CR-48 的终端中输入 hcitool scan 扫描蓝牙设备,你将会看到周边的设备列表以及它们的 Mac 地址
  6. 在终端中输入 hcitool cc xx:xx:xx:xx:xx:xx 连接设备,后面那堆叉子是你想要连的设备的 Mac 地址
  7. 接下来会问你要一个设备的授权码,这个要看设备的说明书,一般是0000或者8888啥的,命令格式为 hcitool auth xx:xx:xx:xx:xx:xx
  8. 搞定收工

看看 Chrome OS 里独有的实验室项目

0

Chromeexperimentsflag-550x282

在Chrome里进入“about:flags”可以设置很多实验项目,Chrome OS当然也有这个功能,但它作为一个操作系统,拥有很多Chrome所没有的实验项目:

  • Media Player:打开之后,你才能直接播放邮件里收到的那些媒体文件。不过目前还很简陋,如果播放的是图片文件,那么依然只能在新标签页里观看而干不了别的。
  • Advanced File System:任何操作系统都需要有一个文件系统,尽管这个实验项目叫做高级文件系统,但其实很低级,打开之后你才能在新标签页里看到插入的U盘或USB硬盘里的文件,但似乎目前无法在目录之间跳转,囧。
  • Remoting:这就是传说中的Chromoting功能──让你在Chrome OS里遥控其它系统的桌面,不过目前只能将CR-48本身作为客户端被另外一台电脑里的Chrome浏览器遥控。
