Google TV is coming

http://www.downloadsquad.com/2010/10/04/google-tv-site-launches-answers-a-lot-of-questions/

Google TV is coming -- and judging by the new Google TV website, it's coming soon. Via the medium of shiny, black, stylish imagery, the site goes a long way to answering any and all questions you might have about the service. For sitting-in-the-living-room TV watchers it soundsreally cool. If you sit at your computer all day, however, the feature list feels a little mundane. If you want to get in on the Google TV goodness, you will either need to pick up an incredibly expensive Sony Internet TV, or grab the standalone Logitech Revue (which will probably cost $200-$300). Neither device is currently available, but the Revue will probably launch after the Logitech event on Wednesday. Incidentally, if you're poking around the Google TV site, there's a link to a 'Google TV blog' at the bottom of the page -- but it's invite-only... just a temporary issue, I'm sure!

用数字衡量网络营销效果：

－－网络营销效果可以100%以数字来衡量

1.访问页面：网络推广的访问者访问 5个页面以上才是有效流量。访问10个页面以上是高质量的流量，访问2个以下页面是垃圾流量。

如何用数字判断一个网站：

1.访问量：alexa，chinaz查询工具。

2.网络流行度：搜索网站名，搜索结果越多相对来说越流行。

3.行业排名：查询艾瑞的排名。

4.网络新闻曝光率：用baidu新闻搜索。

5.SEO表现：收录与PR，排名。

6.百度指数：百度指数是用以反映关键词在过去30天内的网络曝光率及用户关注度。

7.每天新增注册用户数＝UV*1%＝80000*1%＝80

8.活跃用户＝注册用户/10＝100000*10%＝10000

9.最高同时在线＝活跃用户*20%＝10000*20%＝2000

10.收费交易客户数＝活跃用户*5%＝10000*5%＝500

11.销售额：收费交易客户数*商品平均价格200＝10000

按照以上方法看不到对方内部数据也能大致判断这个网站很多数据。

谷歌网址缩短服务goo.gl正式发布

http://www.williamlong.info/blog/archives/559.html

　　谷歌网址缩短服务goo.gl向公众开放，现在任何人都可使用浏览器访问goo.gl使用该服务。此前，该服务仅向使用谷歌工具栏的用户开放。

　　谷歌短网址服务的优势在于速度和稳定性，较小的公司运营的短网址服务的运营质量和稳定性难以保证。此外，谷歌短网址服务还提供类似bit.ly的统计功能，该服务能够记录网址被点击的次数、时间、频率等数据。谷歌还通过追踪这些数据判定特定链接是否流行、得到授权或安全。

　　Twitter也通过t.co域名提供网址缩短服务。

Kapitall is a massive, beautiful stock market playground

http://www.downloadsquad.com/2010/09/29/kapitall-is-a-massive-beautiful-stock-market-playground/

Kapitall is one of the most impressive finance-related websites I've recently come across. The site requires registration (which is free, but you do have to opt out of their newsletter) -- but in return it provides you with an incredible amount of financial data.

The experience is very visual. You get a large canvas, which they call "the Playground." You can search for companies by their stock symbols or by their names. (For example, I didn't know that Oracle is ORCL, so I just searched by name.) Each company gets a large icon on your playground, with the company logo, their name, and their segment ("TECHNOLOGY" for Oracle). Icons can be grouped together, dragged around, and organized in any way you wish.

To dig into a single company, double-click its icon. You get a snapshot page that shows you a one-year performance graph, a company synopsis, current market cap, management details, analyst ratings, and more. You also get to see "Monthly Community Activity" for the company, which lets you determine how much Kapitall buzz there is around a given company.

You can also analyze company data in all sorts of ways. One neat tool is the Compar-O-Matic, which shows you statistics for two or more companies. You can also see statistics over time. Here's a fun fact: in October 2008, Apple's market cap was $100.7B, versus Oracle's $104.6B. Today, Apple stands at $221.2B with Oracle at $109.8B. That's pretty intense, especially when you play it back month-by-month and see how the stock behaves.

This is just scratching the surface of this massive tool, really. If you have any interest in the stock market and in cool tools to chart it and learn about it, you should definitely check out Kapitall.

System Silencer – 系统消声器

http://www.appinn.com/system-silencer/

System Silencer 是款从字面意思上很难理解的软件，它能让电脑在空闲一段时间后干一些事情，比如静音、隐藏任务栏图标、终止进程、运行程序等等。@Appinn

System Silencer 很有意思，让电脑空闲一段时间，意味着大多数时候使用者应该离开了电脑，或者睡着了。就在这个时候执行一些任务，还是相当实用的。

目前支持的任务如上图：静音、显示桌面、隐藏任务栏图标、隐藏桌面图标、隐藏某个打开的窗口、干掉进程、运行程序、关闭显示器、锁定系统。

比如，你可以设置电脑闲置10分钟自动静音，这样放着的音乐会静音就不会干扰到别人了。在比如自动干掉浏览器，这样别人就不知道你在上哪些网站了。关闭显示器是许多软件都支持的功能，系统自身也支持。

总之是款十分有想象力的软件，同学们想到怎么玩了吗？

Ten Essential Linux Admin Tools

http://www.linux-mag.com/id/7870?hq_e=el&hq_m=1081369&hq_l=4&hq_v=e748951000

Every good Linux System Administrator has a set of tools they reach for again-and-again. Here are ten must haves for your virtual utility belt.

Ken Hess

Sunday, September 26th, 2010

System Administrators (SAs) need a set of tools with which to manage their often unmanageable systems and environments*. These ten essential Linux administration tools provide excellent support for the weary SA. Those listed aren't your standard list of tools deemed essential by industry bystanders. These are tools that have proven track records and have stood the test of time in the data center.

1. Webmin - Webmin is the ultimate web-based management platform for Linux and several other operating systems. Written in Perl, it simplifies and streamlines standard administrative tasks. Additionally, Webmin helps you configure very complex implementations of Apache, MySQL and SendMail. If you haven't experienced Webmin, you should, it'sthe essential administration tool.
2. byobu - If you're a screen user, byobu is the next step. If you haven't usedscreen, you should try byobu. Byobu is a Japanese word for the decorative screens or room dividers that often adorn Japanese homes. Hence, the name for a more decorative form of the screen utility. Linux people are nothing if not clever in their naming of projects.
3. tcpdump - It sounds crazy but you'd be surprised by how many times that System Administrators need to analyze network packets to help troubleshoot obscure problems that plague their systems. Tcpdump is the right tool for the job of analyzing network traffic. It isn't beautiful or elaborate but it does exactly what its name advertises: It dumps IP-related traffic to the screen or to a file for analysis.
4. Virtual Network Computing (VNC) - In its many incarnations (TightVNC, UltraVNC,RealVNC), VNC has become one of the most readily recognized and widely utilized remote access tools in the System Administrator's toolbox. Its broad acceptance is due in part to its platform-independence. VNC is easy to install, simple to configure and available for almost every contemporary operating system.
5. GNOME Partition Editor (GParted) - What's better than fdisk? GParted. You have to love the power of this program, since you can boot to a Live CDROM and create, delete and resize your partitions without destroying any existing data. And, it works on almost every imaginable filesystem, even NTFS. For best results, download a Live CD/USB/PXE version and keep it handy.
6. DenyHosts - DenyHosts is a Python script that allows you to actively monitor your systems for attempted unauthorized logins via SSH and subsequently deny access to the originating host system. Denyhosts records the denied entries in /etc/denyhosts.conf. No System Administrator should bring up a system without it.
7. Nagios - Nagios is an extensive and somewhat complex network monitoring tool. It has the ability to monitor a variety of hosts, services and protocols. It is an enterprise class tool that is essential in every network regardless of size or complexity. With Nagios, you can monitor, alert, resolve and report on network problems. It also has trending and capacity planning capabilities. Nagios is an extrememly extensible tool through its plugins, addons, extensions and modules.
8. Linux Rescue CD - Numerous rescue CDs exist for every task or imaginable situation. There are a three notable standouts in the crowd for those of you who don't have one of these in your arsenal: The Ubuntu Rescue Remix, Parted Magic and GRML. Ubuntu Rescue Remix is a command line-based data recovery and forensics tools compilation (CD or USB). Parted Magic is a super diagnostic and rescue CD/USB/PXE that contains extensive documentation. GRML is a Debian-based live CD that contains a collection of System Administrator tools for system rescue, network analysis or as a working Linux distribution.
9. Dropbox - Dropbox, as described in "Dropbox: Painless and Free Backup" is an essential backup and cross-platform file exchange tool. With Dropbox, you can leave home without your essential toolbox but still keep it with you where ever you go.
10. Darik's Boot and Nuke (DBAN) - Described by its developers as "a self-contained boot disk that securely wipes the hard disks of most computers", DBAN is an essential decommissioning tool for those who have to dispose of systems that are no longer in service. DBAN also assures System Administrators that data from any previous operating system installations will be unrecoverable. DBAN isn't the fastest tool on the planet but it is very thorough and wipes all detectable disks securely and completely.

* It's unfortunate that no set of tools exist to manage the unmanageable users in our midst.
