BURLINGAME, CALIF. -

Taking a page from Apple's playbook, Dell is hiring designers as it moves away from its old model of building custom-made computers and begins bypassing traditional retail outlets in order to sell its machines directly to customers.

Dell (nasdaq: DELL - news people ) employees say the company is snapping up design talent as it hustles to crank out fresh PC and notebook designs, and theWall Street Journal reported Friday that Dell is trying to sell its factories as well.

The moves come as the Round Rock, Texas-based company is struggling to improve its profitability, even as it slashes prices to keep sales growth on track. Dell shares fell 11.9% on Aug. 29, the day after the company reported earnings of $616 million, or 31 cents per share, well short of the consensus estimate of 36 cents per share (See "Tech Tanked By Dell.")

The news was another setback in Dell's efforts to get its profit machine back on track. In the late 1990s, Dell tore through the PC industry with its hyper-efficient, built-to-order manufacturing model.

The problem: Much of the PC business has shifted to laptops. Unlike PCs, the slim machines are labor intensive to build. Moreover, their light weight makes it easy to ship them directly from overseas contract manufacturers to customers in the U.S. market, analysts say.

"With the shift to notebooks, and even the mini-notes and the low-priced, low-featured notebooks, all of that will be made offshore," says Shannon Cross, an analyst with Cross Research.

Meanwhile, the drab designs that once appealed to business customers who were more concerned about price than good looks won't work in retail, where Dell has turned in an effort to bolster its consumer business. It's also a channel where Dell's build-to-order advantage does it little good.

By contrast, Dell competitors Apple (nasdaq: AAPL - news people ) and Hewlett-Packard (nyse: HPQ - news people ) have long concentrated spending heavily on design and new product development, while relying on overseas contract manufacturers to build their machines.

That means Dell could have a tough time getting top dollar for its factories, particularly in the U.S.

Cross, however, believes Dell needs to shift its focus to research and development and design, rather cranking out custom-built computers and selling them directly.

Dell is already moving to produce machines, especially laptops, with more distinctive designs and features aimed at setting its wares apart from Apple's and HP's (see "Dell's Laptop Strategy.") However, Dell still doesn't sink as much into research and development as its rivals.

For its latest quarter, Dell spent just 1% of its sales revenue on research and development. Apple, by contrast, sank 3.9% of its sales into research and development.

Dell, however, may have little choice.

"Their core differentiator no longer works," Cross says.

Dell did not immediately respond to a request for comment.

Dell now owns 12 manufacturing and distribution centers, including 5 million-square-feet of space and 850,000 square-feet of leased space, according to its latest annual report. In March, however, Dell announced it would close its Austin, Texas factory--the one closest to its Round Rock headquarters--leaving it with 11 facilities.

While the factories are scattered around the world, five of them--excluding the Austin facility--are based in the U.S., where labor costs are high. They include a factory in Winston-Salem, N.C., facilities in West Chester, Ohio, Lebanon, Tenn., Nashville, Tenn., and a facility run by Dell's high-end Alienware unit in Miami.

Overseas, Dell has one facility in Hortolandia, Brazil, two in Ireland, one in Poland, and one each in China, Malaysia and India. By contrast, Apple owns just one factory, in Cork, Ireland, relying on contract manufacturers to do the rest of its work.

Apple or Microsoft


D-day for Apple, Microsoft

D-day for Apple, Microsoft


On September 9th, both Apple and Microsoft will show off something old and something new. Who do you think will steal the day?


Whose products excite you more -- Microsoft's, or Apple's? Both companies have chosen the 9th of September to showcase theirwares; upgraded and new. 

On September 9, Apple is expected to refresh its lineup of iPods, while Microsoft is holding a farewell for the laser mouse - along with the introduction of new Zune models, and webcams (LifeCams) with 8 megapixel sensors, 5X zoom, and hi-definition recording. 

So, who do you think is going to steal the show on the 9th of September - Microsoft, or Apple?

India among top

BHEL, Airtel, HDFC among 10 Indian firms on Forbes' list

Ten Indian companies led by Bharat Heavy Electricals Ltd (BHEL), Bharti Airtel and HDFC Bank are on the Forbes' list of 50 of the best of Asia-Pacific's biggest listed companies, out of a universe of 500.

Asian Fab 50 Companies' ranking is topped by Taiwanese computer maker Acer, while BHEL and Airtel are the top ranked Indian companies occupying the fifth and sixth spots on the list.

Though the Mukesh Ambani-led Reliance Industries Ltd (RIL) has a market value of $77.7 billion, making it the biggest Indian firm, it is ranked 39.

Forbes described its criteria for inclusion on the Fab 50 list as: 'We look at long-term profitability, sales and earnings growth, stock price appreciation and projected earnings for every company in the region with revenues or market capitalisation of at least $5 billion.'

Thus, from Indian companies, BHEL and Airtel are followed by private sector lender HDFC Bank (22), IT giant Infosys Technolgoies Ltd (25), diversified conglomerate ITC Ltd (27), engineering and infrastructure firm Larsen and Toubro (L&T) (30), auto maker Mahindra & Mahindra (34), steel major Tata Steel (44) and software and services company Wipro Technologies (46).

India with 10 companies comes second on the list after China which has the maximum representation of 13 firms. Hong Kong has another five, Taiwan six and Australia seven companies on the list.

'Indian companies once again had a strong showing, with 10 making our cut. Infosys and Wipro, perennial top performers, are back for the fourth year. RIL, BHEL, L&T are back for the third year,' the US business magazine said in a report accompanying the list.

'Consumer-oriented companies such as Bharti Airtel, HDFC Bank, Mahindra & Mahindra and ITC are growing with India's middle class,' it added.

About BHEL, the magazine said: 'With the Indian government's commitment to achieve 'power for all by 2012', the country's largest energy equipment provider is firing up plenty of juice. Still 68 percent state-held, it holds a commanding 60 percent to 65 percent market share of India's power capacity additions.'

On telecom major Airtel, the report said: 'As many as 10 million new subscribers sign up every month for wireless access in India. One in four sign up with Bharti Airtel, not only to make calls but also to access the Web, download cricket scores and send billions of text messages.'

On Tata Steel, partly owned by the Tata group, the magazine said Ratan Tata transformed his steel company from a South Asian foundry into an enterprise spanning the rest of Asia, Europe and the US with $13 billion takeover of Anglo-Dutch Corus group last year.

Cryptography Lesson 1



1. INTRODUCTION

Does increased security provide comfort to paranoid people? Or does security provide some very basic protections that we are naive to believe that we don't need? During this time when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for commerce, security becomes a tremendously important issue to deal with.

There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography, which is the focus of this chapter. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. The reader is advised, then, that the topics covered in this chapter only describe the first of many steps necessary for better security in any number of situations.

This paper has two major purposes. The first is to define some of the terms and concepts behind basic cryptographic methods, and to offer a way to compare the myriad cryptographic schemes in use today. The second is to provide some real examples of cryptography in use today.

I would like to say at the outset that this paper is very focused on terms, concepts, and schemes in current use and is not a treatise of the whole field. No mention is made here about pre-computerized crypto schemes, the difference between a substitution and transposition cipher, cryptanalysis, or other history. Interested readers should check out some of the books in the bibliography below for this detailed — and interesting! — background information.
