Google has seen enough of Microsoft's Windows operating system, suspending internal use of the OS amid security concerns related to the attack on its network late last year, according to a report.

The Financial Times reported late Monday that Google has begun telling new employees that they are no longer able to request Windows PCs, giving them the choice of Mac or Linux systems. Google has long offered its employees their choice of work operating system but will no longer do so, The Financial Times said, after an attack on Windows and Internet Explorer 6 resulted in the theft of Google intellectual property, believed to be source code, late last year.

Rumors to this effect surfaced earlier in the year, but CNET was unable to confirm them at the time. Microsoft has never been a friendly face inside the Googleplex, but Google's engineering-driven culture and need to test its software on a variety of systems usually meant that at least some portion of its employees preferred the Windows environment. Some Google employees will still be able to use Windows machines, but they will have to get special permission, according to the report.

Later this year Google will begin directing employees toward Chrome OS systems, Google CEO Eric Schmidt told CIOs attending a Google seminar on cloud computing in April. Google believes the browser-based operating system will be "inherently more secure" than alternative operating systems, Schmidt said at that event.

Google declined to comment "on specific operational matters."

20 Ways To Increase Laptop’s Battery Life

http://www.makeuseof.com/tag/20-ways-to-increase-the-life-of-your-laptops-battery/

Mobile computing has got better with lighter components, better chips and faster processors. But the Achilles heel of a laptop has remained its battery. So here are we are going to look at ways to increase laptop battery life.

Modern graphic intensive operating systems and resource hungry applications are cutting down the life of your laptop's battery every day. The average battery life per continuous use still stands at a maximum of three to four hours. So, a fast depleting battery could very swiftly put the crutches on your 'mobile' road trip.

Falling just short of carrying an extra pack of batteries in the back-pack, are several ways to keep the juice flowing through the batteries.

1. Ship shape with a defrag

Regular defragmentation helps to arrange data more efficiently thus making the hard drive work less to access the data. The quicker the moving hard drive works lesser is the load placed on the battery. Thus, your batter can last longer. The effect is minimal, but this efficiency goes hand in glove with hard drive maintenance.

2. Kill the resource gobblers

End the background processes that are not vital. Monitor the resource usage through a 'Ctrl-Alt-Del'which brings up the Windows Task Manager (in Windows). If you're not on the internet, it is safe to shut down the immediate non-essential programs running in the taskbar like the antivirus and the firewall. Weed out unnecessary programs running as start-ups by launching the System Configuration Utility from Run – Msconfig – Tab: Startup. Uncheck the programs which you don't want to launch and reboot the computer once.

3. Pause the scheduled tasks

It may be a defrag or a virus scan, but make sure it is scheduled for a time when you are near a power outlet. If not then nix them for the moment.

4. Unplug external devices

USB devices are the biggest drainers of battery power. Unplug all external devices like an external mouse, PC cards, Wi-Fi, external speakers, Bluetooth and even an attached iPod.

5. Empty the CD/DVD Drives

Even if you don't intend to use it, don't leave any CD/DVDs as leftovers in the drives. A spinning drive sucks battery power like a sponge.

6. Go local

Desist using the DVD/external drives while running on batteries. Shift the content to the hard drive or run using (free) virtual drives like Pismo File Mount or even Microsoft's Virtual CD ROM Control Panel.

7. Lower the lights

The LCD screen of a laptop is another huge power sink. Calibrate the brightness to the lowest level you can tolerate using the Function key toggles or using the Display Settings applet in the Control Panel.

8. Kill the sounds

Mute the speakers and try avoiding the use of multimedia software to maximize the battery life. Installed sound schemes also drain a battery perceptibly.

9. Rid the screensaver

To maximize battery life by a little, switch off the screensaver.

10. Visit Power Options

Get familiar with power management through the 'Power Options' applet in the Control Panel. Both XP and Vista come with advanced power management features which shut off components like the monitor and/or the hard drive after specified intervals. This again depends on the chosen 'Power Schemes' (for XP) in the same applet. For instance in XP, 'Max Battery' under Power Schemes can be selected for maximum battery optimization.

Similar settings can be found under 'Mobile PC' in the Control Panel of Vista.

11. Turn off the looks

Today's OS's like Windows Vista come with features like 'Aero Glass' which are resource guzzlers. One can turn it off and go for the 'Classic' appearance which consumes less power. In Vista, click onDesktop – Preferences – View Colour – Appearance – Classic Appearance and Windows Basic graphical interface. In XP it's – Display Properties – Theme – Windows Classic.

Linux and even Macintosh are better optimized for longer battery life.

12. Hibernate is better than Sleep

In the Stand By mode (or sleep mode), the computer turns of the hard drive and the display but memory remains active while the CPU slows down. This draws on the battery. In contrast, hibernation mode is better because the computer saves the current state and shuts itself down completely thus saving power.

13. Get the most…work on the least

Working on too many programs while on the battery is a sure fire power drainer. Keep use of graphic intensive applications to a minimum. Working on a spreadsheet consumes much less than playing your favourite game. To increase the life of the battery open just one or two programs concurrently.

14. Ram in more RAM

Adequate RAM reduces the load on Virtual memory which by default resides on the hard drive. Though every extra bit of RAM uses up more power, it increases overall savings by short cutting access to the power hungry hard drive.

15. Keep it clean

A laptop with blocked air vents will generate more heat thus reducing the life of the battery. Clean the air vents regularly to keep operating temperatures low. Allow for open space around the vents for air to circulate freely. Keep the area around the laptop clean to avoid entry of dust.

16. Temperature is a silent killer

Undue heat kills off a battery slowly but surely. Avoid leaving the laptop under direct sunlight or inside a closed car.

17. Avoid the memory effect

A problem more for the older Ni-MH batteries than for Li-Ion batteries on which most modern laptops run. Memory effect relates to the loss of battery charge when they are repeatedly recharged after being only partially discharged. It can be prevented by discharging the battery fully and then completely recharging it. Li-Ion batteries on the other hand have no problems with partial discharges and re-charges and complete discharge is never recommended for this type.

18. Update software and drivers

This sounds a bit incongruous but then newer drivers and software are often designed to be more efficient (and hopefully less resource hungry).

19. Use the right adapter

Ensure that the adapter you use to charge the laptop battery is an original one or one with the correct specifications. A mismatch in the wattage could cause an overload thus damaging the laptop and the battery.

20. Pack it up

If you don't plan to use the laptop on batteries for quite some time, ensure that the charge is nearly 40 percent – remove the batteries and store it in a cool place.

A typical lithium ion battery has an overall average life of 2-3 years. With some care and caution, its mortality can be delayed.

Ecommerce Dictionary: 20 Words to Know

http://www.ecommerce-guide.com//article.php/3884326
By Vangie Beal
May 26, 2010

From launching an e-commerce website to understanding industry regulations, this Ecommerce Dictionary -- with 20 definitions and links to helpful tips and how-to articles on Ecommerce-Guide.com -- will make your transition from retailer to e-tailer easier a much easier task to understand.

Ecommerce Hosting Lingo

Before you can open up shop online, you first have to find a place to host thewebsite. This Ecommerce Dictionary explains some of the more common types of ecommerce site hosting phrases you are sure to encounter when setting up your online business.

Dedicated hosting: Sometimes referred to as a dedicated server, it means your website is the only one on hosted on the server. With a dedicated server, security is often tighter; however you will largely be responsible for the server management -- not just the website.

Shared hosting: Sometimes called virtual hosting, or referred to as a shared server, it basically means your website will share resources with other websites as multiple sites are running (hosted) on the same physical server.

Virtual host: A provider of Web services that includes Web server functions and Internet connection services. A virtual host is often used by companies or individuals that do not want to purchase and maintain their own Web servers and Internet connections.

Web host: The company, or service provider, that provides server space, Web services and file maintenance for Web sites controlled by individuals or companies that do not have their own Web servers.

Web server: A computer that delivers Web pages. Every Web server has an IP address and possibly a domain name. When a user types your domain name into a Web browser, it sends a request to the server to fetch the page.

Common Ecommerce Website Processes

The following ecommerce phrases are ones you will encounter when designing, hosting and launching your own ecommerce website. There are a number of ecommerce standards and financial accounts you will need to be familiar with before you can accept online payments.

Credit Card Interchange: The phrase used to describe the process involved in completing a credit card transaction. The "Interchange" refers to all organizations involved in the transaction, including processors, acquirers and issuers.

Merchant Account: The type of account a business obtains from their banking institution that allows you to accept credit card payments. Merchant accounts are usually required for a retailer or e-tailer to accept customer credit cards and electronic payments

Payment Gateway: A service provided by a third-party organization, that automates a payment transaction between the shopper and merchant. A payment gateway is actually a system of computer processes that process, verify, and accept or decline credit card transactions on behalf of the merchant through secure Internet connections.

Shopping Cart: Ecommerce software that acts as an online store's catalog and ordering process. A shopping cart is the interface between a company's Web site and its deeper infrastructure, allowing consumers to select merchandise; review what they have selected; make necessary modifications or additions; and purchase the merchandise.

Commerce Server: Web software that runs some of the main functions of an online storefront such as product display, online ordering and inventory management. This type of software is also called storefront software.

Ecommerce Marketing: Email Marketing Lingo

Learning email marketing lingo is important to help you understand what features and options you will have for tracking your email marketing campaigns. To get you started, here are ten email marketing terms you should know before starting a subscriber list for your ecommerce business.

A/B split: A type of marketing test where an email subscriber list is split into two groups; every other name in the list is sent one email message and vice versa to see which marketing message has the most successful response.

Conversion rate: In online marketing, this phrase refers to the percentage of visitors who take a desired action. For example the percentage of people who click a hyperlink in your message and make a purchase from your Web store.

Direct digital marketing: An online marketing method that is addressable -- meaning you can identify the recipient of the email message you're distributing. Addressability comes in a variety of digital forms including an email address, a Web browser cookie or a mobile phone number.

Event triggered e-mail: A message sent to list subscribers based on an event. For example, a special message or discount coupon delivered to subscribers on their birthday or anniversary dates. The events are determined based on the information the subscribers provided when joining the list.

Open rate: This is a common email marketing phrase that basically means the number of list subscribers who opened the email message you sent. Open rates are used to track how successful your email marketing campaign is.

Ecommerce Laws, Standards and Protocols

CAN-SPAM: The CAN-SPAM Act applies to almost all businesses in the U.S. that use email, and provides recipients of spam with the right to opt-out of these spam messages, and have their opt-out (or unsubscribe) request acted upon. Under the CAN-SPAM Act of 2003, permission of the email recipient is not required prior to sending out the emails, however if a recipient wants to unsubscribe or opt-out of the mailings then the business must stop sending the emails as per the opt-out request or face severe penalties.

Certification authority: An organization or company that issues digital certificates used to create digital signatures. The role of the certification authority (CA) is to guarantee that the individual or business that has been granted the unique certificate is, in fact, who they claim to be. CAs are a critical component in electronic commerce because they guarantee that the two parties exchanging information are actually who they claim.

Electronic Data Interchange: The Electronic Data Interchange (EDI) is a standard for the transfer of data between different companies using computer networks. EDI is becoming increasingly important as an easy mechanism for companies to buy, sell and trade information.

PCI-DSS: Short for Payment Card Industry (PCI) Data Security Standard (DSS), it is a standard that all organizations, including online retailers, must follow when storing, processing and transmitting their customer's credit card data. To be PCI complaint companies must use a number of security features, such as a firewall between a wireless network and their cardholder data environment, and also use the latest security and authentication. The PCI DSS standard specifies 12 requirements for best security practices

SSL: Short for Secure Sockets Layer, SSL is a protocol for transmitting private documents via the Internet. SSL uses a cryptographic system with two keys to encrypt data -- a public key known to everyone and a private or secret key known only to the recipient of the message. Many websites use the protocol to obtain confidential user information, such as credit card numbers.

开源团购源程序

http://www.williamlong.info/blog/archives/443.html

最近流行团购,美国的Groupon团购网站盈利之后就有不少模仿这家网站的团购网站,我也研究了一些团购网站,看了一下代码,发现有两个网站提供开源的团购源程序下载。记录了一下。
程序都是基于PHP+MySQL的。

  1、久动团购程序 http://www.jiuder.net

  2、最土团购程序 http://www.zuitu.com

基于社会化网络的B2C电子商务模式

http://www.williamlong.info/archives/2192.html

  社会化网络营销和电子商务的结合是近年来新型Web 2.0电子商务网站的发展趋势,这种新型的电子商务模式和传统的B2C网站有很大不同,有很多独特的模式,下面我就以Groupon网站为例分析一下基于社会化网络的B2C电子商务的商业模式。

  Groupon并不是一个纯粹的电子商务网站,它是电子商务、web2.0、互联网广告以及线下模式的结合体。目前的表现形式是团购,收入模式是依靠收取提成等,据《纽约时报》报道,美国团购网站Groupon恐怕已经成为史上最疯狂的互联网公司。Twitter达到10亿美元估值用了3年时间,Facebook达到10亿美元估值用了2年时间,而Groupon只用了一年半。

  Groupon的商业模式特点:

  1、电子商务的社会化营销:微博、SNS、电子邮件等社会化网络营销。

  2、极低价格的产品:大多是非实物产品,因为实物产品很难有低折扣,一些团购网初期有可能自己贴钱营销。

  3、用户习惯培养:每天一次服务,和博客的每天更新非常像,用来提高用户黏度。

  4、界面简单:简单就是美,大为简化购物流程,减少用户的购物时间,提高消费者的购买效率。

  5、稀缺营销:每天只卖一个产品,购买时间倒计时,购物人数有底线。

  5、线上服务:替代街头发小广告的服务

  6、用户群体精准:习惯于使用网络购买方式和容易被折扣所吸引的年轻人……

  7、吸纳优质商户:通过商务独特的商品或服务吸引用户。

Groupon

  Groupon网站的SWOT分析:

  优势:

  1、成本低廉:有较为低廉的团购程序可购买,网站简单,易维护,运营成本低。

  2、盈利快:做为电子商务网站,从一开始就能实现盈利,以保证网站的长期持续发展。

  3、政策扶持:某些地方政府,例如深圳,对于互联网电子商务表现出扶持的态度,大多数政府部门也不会有意阻碍电子商务网站的发展。

  劣势:

  1、竞争激烈:已经存在大量竞争对手,较为知名的如美团网等。

  2、运营困难:运营网站对消费类商家可能不熟悉,联系商家确认产品有难度,通常网站可能缺少社会化媒体推荐经验,也缺少个人用户销售经验。

  机遇:

  1、市场潜力:一些核心一线城市还缺少足够服务,市场潜力大,目前还没有类似社会化电子商务产品的垄断产品存在。

  2、风险投资:运营此类业务的网站有获得风险投资的先例。

  威胁:

  1、发展前景:新型的电子商务模式,前景不明朗,有可能会失败;目前在国内还没有成功案例,未来具有很大的不确定性。

  2、运营风险:运营模式可能会带来人力资源成本,线下销售团队规模远超线上团队。

  总结:

基于社会化网络的B2C电子商务模式

  上面说了这么多,用一张图片来总结更清晰一些,上图是我做的一个关于电子商务网站业务分析的图片,不仅仅包括Groupon,还包括Blippy、Alibaba、Intuit等网站,限于篇幅就不再多说。

Google offers Web designers hosted, open-source Web fonts

http://googlecode.blogspot.com/2010/05/introducing-google-font-api-google-font.html

Wednesday, May 19, 2010

Today we are excited to announce a collection of high quality open source web fonts in the Google Font Directory, and the Google Font API to make them available to everybody on the web. For a long time, the web has lagged print and even other electronic media in typographic sophistication. To enjoy the visual richness of diverse fonts, webmasters have resorted to workarounds such as baking text into images. Thanks to browser support for web fonts, this is rapidly changing. Web fonts, enabled by the CSS3 @font-face standard, are hosted in the cloud and sent to browsers as needed.

Google has been working with a number of talented font designers to produce a varied collection of high quality open source fonts for the Google Font Directory. With the Google Font API, using these fonts on your web page is almost as easy as using the standard set of so-called "web-safe" fonts that come installed on most computers.

The Google Font API provides a simple, cross-browser method for using any font in the Google Font Directory on your web page. The fonts have all the advantages of normal text: in addition to being richer visually, text styled in web fonts is still searchable, scales crisply when zoomed, and is accessible to users using screen readers.

Getting started using the Google Font API is easy. Just add a couple lines of HTML:

<link href='http://fonts.googleapis.com/css?family=Tangerine' rel='stylesheet' type='text/css'>

body { font-family: 'Tangerine', serif; }
The Google Font API hides a lot of complexity behind the scenes. Google's serving infrastructure takes care of converting the font into a format compatible with any modern browser (including Internet Explorer 6 and up), sends just the styles and weights you select, and the font files and CSS are tuned and optimized for web serving. For example, cache headers are set to maximize the likelihood that the fonts will be served from the browser's cache with no need for a network roundtrip, even when the same font is linked from different websites.

These fonts also work well with CSS3 and HTML5 styling, including drop shadows, rotation, etc. In addition, selecting these fonts in your CSS works just the same as for locally installed fonts, facilitating clean separation of content and presentation.

The fonts in the Google Font Directory come from a diverse array of designers, including open source developers and highly regarded type designers, and also include the highly acclaimed Droid Sans and Droid Serif fonts, designed by Ascender Corporation as a custom font for Android. We invite you to browse through the directory and get to know the fonts and designers better. Since all the fonts are open source, you can use them any way you like. We also have a separate project hosted on Google Code for downloading the original font files. Since they're open source, they can be used for just about any purpose, including for print.

We're hoping designers will contribute many more fonts in coming months to the Google Font Directory. If you're a designer and are interested in contributing your font, get in touch with us by completing this form.

To showcase the Google Font API, Smashing Magazine has relaunched their site using the open source Droid font hosted by Google. We're excited about the potential for integrating the Google Font API into many types of publications and web applications. For example, the new themes for Google Spreadsheet forms are a great example of a rich visual experience using web fonts.

This is just the beginning for web fonts. Today, we're only supporting Western European languages (Latin-1), and we expect to support a number of diverse languages shortly.

How to Choose a Good Web Host Provider

http://www.smallbusinesscomputing.com/features/article.php/52721_3882486_1/SMB-Guide-How-to-Choose-a-Good-Web-Host-Provider.htm

Shared vs. Virtual Private Server vs. Dedicated Web Hosting

Most Web hosting providers that cater to small businesses provide shared Web hosting, where many Web sites are housed on the same server. The advantage of shared Web hosting is that it's typically inexpensive (less than $10/month), because the provider can spread out the cost of maintaining the server among many customers. While websites are kept separate, there can, however, be problems with availability/uptime with this option.

For small businesses with relatively light traffic and/or sales (i.e., not an ecommerce business), shared Web hosting is fine. However, if you run an ecommerce business, you may want to consider using a provider that offers a VPS (Virtual Private Server, also referred to as a Virtual Dedicated Server) solution, where your site sits on its own virtual server and will not be affected by other customers.

Another option is dedicated Web hosting, where you lease a whole server for your website(s). While this option is more expensive than shared and VPS Web hosting, if you have a high-traffic small business ecommerce site that is doing thousands of dollars of business each month, and need fast, ecommerce Web hosting, this may be your best bet.
