Google's Android for phones nearing release

Google is everywhere, with its ubiquitous Web search engine, Google Maps for navigation, Google Docs online office suite, Google Checkout shopping and most recently, Google Chrome Web browser. Next up: Google’s Android operating system for mobile phones, likely to debut in the weeks ahead.




The first mobile device built around Android will be carried by T-Mobile in a still-unnamed handset designed by Taiwanese smartphone powerhouse HTC. The Android phone will go up against Apple's iPhone, Research In Motion’s BlackBerry and a host of devices powered by Nokia’s Symbian and Microsoft’s Windows Mobile operating systems. (Msnbc.com is a joint venture of Microsof t and NBC Universal.)

While every market Google has entered is highly competitive, none may be more so than the mobile phone market, specifically the market for smartphones, which can handle e-mail and Web surfing.

Symbian-based phones led in worldwide market share for smartphone mobile operating systems, with 57.1 percent of sales in the second quarter of this year, according to Gartner Research.

That likely reflects Nokia’s status as the world’s largest cell-phone maker. Next in line were Research In Motion, 17.4 percent; Windows Mobile, 12 percent; Linux, 7.3 percent; Apple’s Mac SO X, 2.8 percent; and Palm, 2.3 percent. Another 1.1 percent included Sharp Sidekick devices based on the Danger platform.

In the United States, Research In Motion’s mobile operating system dominates the smartphone market, with 41 percent, according to a February 2008 report by Canalys consulting, with Apple capturing 28 percent, Windows Mobile, 21 percent, and Palm, 9 percent.

Open Handset Alliance backing
While it’s Google that’s putting together Android, it’s also the culmination of work by the Open Handset Alliance, a collaborative group including Google and more than 30 semiconductor and software companies, mobile operators and handset manufacturers. Alliance members include Sprint Nextel, T-Mobile, Intel, Motorola, HTC, eBay, LG and Samsung.

Jason Mackenzie, vice president of HTC America, which uses Windows Mobile in its other phones, is confident about Android’s prospects.

“Millions of people rely on Google services and applications every day on their PCs — whether it’s for search, maps, e-mail,” he said. “We believe that the ability to provide this same rich experience on a mobile device is a powerful proposition for a wide range of consumers.”

While Android is an operating system, it is also an open-source system similar to Linux, upon which it is based. That’s creating a lot of excitement and interest in the kind of programs that will be available for users, including one that can track family members’ whereabouts in an emergency to another that offers a short cooking video, followed by information on nearby grocery stores that carry the ingredients needed for the recipe.

Since its inception, Android has been tweaked and built upon freely by developers, device designers and wireless carriers who have had complete access to Android’s Software Developer Kit. Basically, Android is whatever users and developers want it to be.

That’s in contrast to Apple’s approach with the iPhone. Nine months ago, Apple created a Software Developer Kit offering application makers the same interface and tools Apple uses to develop iPhone software.

But Apple has closely regulated and monitored every program that is being offered through the company’s online App Store.

Android will “create a new, attractive environment to foster innovation and make it easier to bring new ideas to market, ultimately ensuring consumers a richer, more personalized mobile experience,” said Mackenzie.

Android Market
Beyond the touchscreen and customizable home page of an Android device is what will be known as the Android Market for add-on software. After all, a smartphone, just like any computer, is only as useful and engaging as the programs its runs.

On the face of it, it sounds like Apple’s App Store, which has both free and paid programs. But in an Aug. 28 post on the Android Developers blog, Google's Mobile Platform Program Manager Eric Chu touched on some of the differences.

“Developers will be able to make their content available on an open service hosted by Google that features a feedback and rating system similar to YouTube,” he wrote. “We chose the term ‘market’ rather than ‘store’ because we feel that developers should have an open and unobstructed environment to make their content available.”

Francesco Roveta, director of eBay Mobile, is not concerned about a lack of quality control in an open Android Market.

“EBay's experience with marketplaces demonstrates that end-users always determine the success of an application, a business model and a platform,” he said.

Microsoft, Google may go head-to-head

Microsoft's path to expand the Windows empire is leading directly to search king Google.

The software company this month quietly launched a new search program called MSNBot, which scours the Web to build an index of HTML links and documents. The homegrown system--which performs robot functions previously left to Inktomi and other partners--may pose a significant threat to Google if Microsoft fulfills its promise to make the program a cornerstone of its overall PC and services strategies.



MSNBot is believed to be the first step in a multiyear plan to build new search technology that bridges Microsoft's home and business customers. Company executives hope the program will eventually prove to be the elusive technology that binds its various Web sites, applications and, of course, the dominant Windows operating system.

Microsoft could then connect the search engine of its MSN portal to new file technology planned for the next version of Windows, code-named Longhorn, which will make it easier to search e-mail, spreadsheets and documents on PCs, corporate networks and the Web. The result would be a powerful technology reaching from the desktop to the greater Internet that could displace Google as the Web's leading search engine.

"What Google has done in terms of doing a great end-user experience has led us to basically go back and redouble our efforts," Microsoft Vice President Yusuf Mehdi, who oversees the MSN division, said at a conference held by investment bank Goldman Sachs last month. "We are investing a lot to build what we expect and hope will be the best-in-class search service in the near future."

The move begs obvious comparisons to earlier Microsoft campaigns, including the infamous undoing of Netscape Communications in the browser market. But Microsoft is not trying to unseat a leading rival simply to catch up with a market it had underestimated, as it has in previous battles. The company would be moving in its current direction even without the presence of Google, because search is expected to evolve into a pivotal part of its business.

Nevertheless, Microsoft may use some familiar tactics in the search market, most notably by integrating and distributing the technology throughout its many products and services. The company could, for example, embed connections to related Microsoft search and mapping functions directly into Word documents or Web sites built with Windows development tools.

The goal is vintage Microsoft: Keep customers within the Windows universe; build demand through popular functions such as search; and bypass the need for services from competitors. This strategy, in theory, will give consumers more incentive to buy Windows software and use Microsoft services, while taking away revenue that Google receives for search results.
"The fact that Longhorn is on the horizon raises questions to whether search services will be integrated into the Longhorn experience and what the ramifications will be to other folks," said Michael Gartenberg, an industry analyst at Jupiter Research. "Microsoft has long demonstrated they don't have to be best at something, but they have to be good enough for people to use their default settings."

The search initiative is part of a broader Microsoft plan to revamp all of its major product lines, including Windows, MSN, the Office package of business applications, and server software. It is a key business strategy with a mission that's as unwieldy as its name, "Longhorn Wave Innovation."

Stirring up search
The value Microsoft places on search became apparent more than a year ago when the company began outlining plans for Longhorn, which is scheduled to debut in 2005. The operating system will include a central engine that can search a PC's morass of Word documents, Outlook e-mailings, Excel spreadsheets and PDF (portable document format) files with a single tool--a function that has escaped the PC industry, and Microsoft in particular, for decades.

"Microsoft's target will be to create little perceived difference between Web search and local search," said Chris LeTocq, an analyst at Guernsey Research.

Neither Google nor Microsoft made executives available for this report. However, in a recent interview with The Seattle Times, Microsoft executive Jim Allchin said condescendingly: "Google's a very nice system, but compared to my vision, it's pathetic."

Google, for its part, may have to make some critical decisions to avoid a fate similar to that suffered by other Microsoft victims, which have been forced out of their core businesses and into unfamiliar territories. Pressure from Microsoft pushed browser maker Netscape to the Web portal market, for instance, and RealNetworks from media players to subscription content services.

"The big question is: Will Google turn into a portal?" said Matthew Berk, an analyst with Jupiter Research. "The truth of the matter is, they have no idea. They see one market and go after it. They build things literally one day at a time."
Microsoft CEO Steve Ballmer stressed the role of search in the company's strategies as part of an all-hands memo sent to Microsoft employees this month. In discussing new products and marketing related to Longhorn, Ballmer identified search as one area where Microsoft will offer "new end-user functionality and services." As part of his "integrated innovation" message, he said the company needs to "reach out broadly" through search, consumer services and other avenues to grow.

The need for diversity is well warranted. Although Microsoft has more than $40 billion in cash reserves, it has long depended primarily on two products, Windows and Office, to generate the bulk of its profits. The company has had mixed results at best in repeated attempts to establish MSN as a money-making consumer venture, but the company believes that more capable search services may be the key to the portal's success.

The business of commercial search has become a cash windfall not only for Google and rival Overture Services, but also for partners such as MSN, America Online and Yahoo. Google and Overture share revenues with their distribution partners every time someone clicks on a sponsored link. But Google's advantage over Overture stems from its role as a commercial search provider and a highly trafficked engine, allowing it to receive higher margins while decreasing its reliance on portal partners--a model Microsoft is hoping to replicate.

Digging up cash
The numbers show why. Overture contributes heavily to the bottom line of MSN, which receives revenue from the search service in return for exposure on the portal's site. Although Microsoft doesn't break out these figures, MSN executives have compared them in scale with Overture's contribution to Yahoo, which amounted to $54 million last quarter, or 20 percent of its total revenue.

At the same time, while commercial search pays the bills, algorithmic search keeps the customer happy. MSN has deals with Inktomi and LookSmart to power its Web search results, though the future of its deal with Inktomi has been questionable since Yahoo acquired the company late last year.
"At this point, we are interested in developing the technology in-house," MSN group product manager Lisa Gurry said in an interview last week.

If Microsoft holds true to form, signs of its custom search engine will soon proliferate. As the company proved with browsers, media players and so many other products, it has myriad distribution points at its disposal and can exploit them at will to increase usage and market share. Already, sources close to the company say that it plans to incorporate a search toolbar into the Internet Explorer browser that will use MSN's new engine.

Still, for all its resources and influence, Microsoft has yet to find a runaway winner in consumer services--and, in fact, continues to suffer from the failures of its last high-profile initiative launched three years ago. A planned consumer-oriented Web service, called .Net My Services, was eventually shelved because of market confusion, a lack of partners and other factors.

This time, some industry veterans believe, Microsoft may finally have learned the painful lessons of its many miscalculations on Web-related businesses, which date back to the early 1990s when the software giant initially failed to grasp the significance of the Internet as a whole.

"They are not going to make the same mistake twice. They are going to cover all the bases and make sure they have a play in every piece of the Internet," said Laura Didio, an analyst at The Yankee Group.

"They do not like coming in second."

DDR DIMM

Double Data Rate DIMM [DDR-DIMM, DDR DIMM, or DDR1] utilizes the JEDEC standard for Double Date Rate [DDR I] SDRAM. This page covers the DDR memory modules, which may also be found as SO-DIMM, and Micro-DIMM module formats. DDR DIMM modules are produced in two different flavors; registered or unbuffered. Registered DIMMs have their address and control lines buffered on the DIMM to reduce signal loading. Because the Registered DIMM requires a buffer they are more expensive then unbuffered DIMMs.



Unbuffered DIMMs do not buffer the address lines and control lines, so they cost less and may be limited in the amount the system may have installed because of system loading. How ever an unbuffered DDR DIMM is able to operate one clock cycle faster then a registered DIMM.

In addition to the DDR1 DIMM module being registered or unbuffered, the physical size of the module may also vary between DIMM, SODIMM, or Mirco-DIMM. The SO-DIMM and Micro-DIMM formats are used in lap-top computers, while the standard DIMM format is used in desk-tops and work-stations.

Refer to the general Memory Module page for a more complete listing of different types of modules, manufactures and descriptions. DDR modules may be purchased in one of the following speed grades:

...DDR SDRAM:....Double Data Rate SDRAM [DDR200, DDR266, DDR333 are standard]
.........PC1600 (DDR-200 SDRAM); Clock Speed: 100MHz, Data Rate: 200MHz, Through-put 1600MB/s
.........PC2100 (DDR-266 SDRAM); Clock Speed: 133MHz, Data Rate: 266MHz, Through-put 2100MB/s
.........PC2400 (DDR-300 SDRAM); Clock Speed: 150MHz, Data Rate: 300MHz, Through-put 2400MB/s
.........PC2700 (DDR-333 SDRAM); Clock Speed: 166MHz, Data Rate: 333MHz, Through-put 2600MB/s
.........PC3000 (DDR-366 SDRAM); Clock Speed: 183MHz, Data Rate: 366MHz, Through-put 2900MB/s
.........PC3200 (DDR-400 SDRAM); Clock Speed: 200MHz, Data Rate: 400MHz, Through-put 3200MB/s

As the name implies, Double Data Rate interfaces provides two data transfers per clock. The clock is differential. The data is registered when the CK goes high [the + side], and /CK goes low [the - side].
The first generation of DDR memory DDR1 is being replaced by DDR2, or DDR3.

Apple's iPhone wins J.D. Power award

A survey conducted by J.D. Power and Associates found Apple's iPhone generated the highest amount of customer satisfaction among smartphone-using businesspeople.

The survey of almost 1,400 respondents, which was conducted during August and September, ranked the iPhone first on a scale that asked respondents to rate the smartphones for ease of operation, operating system,



physical design, handset features, and battery aspects. Apple's favorite gadget scored 778 points out of a possible 1,000 points, beating Research In Motion and Samsung.

The iPhone received perfect rankings in four of the five categories, with the exception of "battery aspects," in which it only received two golden circles out of five. The survey weighted the other categories more heavily, however. The only other manufacturer to get five golden circles in any one category was RIM, in the battery aspects category.

What is HTML???

HTML stands for Hyper Text Markup Language. It is a type of computer language that is primarily used for files that are posted on the internet and viewed by web browsers. HTML files can also be sent via email.

Although it may seem complex to the uninitiated, HTML is relatively simple. All text, graphics and design elements of a web page are "tagged" with codes that instruct the web browser how to display the files. Such files are easy to recognize because they contain the file extension of 'html' or 'htm'.


In addition to the page content itself, HTML files provide layout and formatting information. HTML is not case sensitive and can be easily updated after the file is created. For the novice web designer, there are many different software utilities and programs available to assist in generating HTML pages.

To format a simple text file into HTML, the user creates tags that start and finish with angle brackets. To end the formatting or change to another format, the HTML developer types the first angle bracket, a backslash, then repeats the command and closes the bracket. For example,

What is HTML?

is the code used to create the heading at the top of this article.

There are different codes for all sorts of other formatting including italics, tables, paragraphs etc. The "A" tag is used to designate words that are to be displayed as hyperlinks to other pages.

If you would like to view a sample of HTML, a good place to start might be the code that was used to generate this very page. Simply click on the "view" menu on your browser and then select "source". It may look complicated, but if you learned the limited number of tags, you would discover that it is a relatively straightforward language.
