Vodafone 2008 Partner Award Goes To Seeker Wireless

Sydney, Australia-/Wi-Fi Technology News/- Seeker Wireless, one of the leading location-based service technology companies announced today that it has been named Innovation Partner of the Year 2008 at a conference hosted jointly by Vodafone New Zealand and Vodafone Australia

The Vodafone Partner Awards were created to recognize excellence in provision of services to Vodafone by its supply partners. This year’s conference focused on the theme “Collective Innovation for Growth”. In keeping with the theme, Seeker’s award recognised the company’s willingness to collaborate at multiple levels to ensure Vodafone was able to effectively enter the fixed-line business with a purely mobile offering.

The contract for which the award was given saw Seeker Wireless providing the world’s most technically advanced and financially efficient zone detection solution in support of Vodafone New Zealand’s recently launched Local Zone product. Created expressly to support fixed mobile substitution strategies, SeekerZone™ allows operators such as Vodafone to motivate subscribers to continue using their mobile phones instead of a fixed line by setting innovative tariffs for subscribers around their “local zone”.

Vodafone has run a joint partner awards between Australia and New Zealand for several years, assessing several hundred suppliers in three categories. This year’s Innovation Award was presented to Seeker Wireless by Ken Tunnicliffe, Vodafone New Zealand’s Director of Technology.

Dr Chris Drane, CEO of Seeker Wireless stated that “making the transition from a start-up with fantastic technology to delivering carrier-grade solutions was a very steep learning curve for us. Our solution moves the SLA bar up from 90% to 99.5% in-zone reliability, an almost unbelievable leap in service level. We are grateful that in Vodafone we had a customer that truly valued what we were doing as a key plank in their strategy for market growth. And by treating our relationship as one of genuine collaboration, Vodafone allowed us to constantly improve our value to them. Along the way, Seeker has become a better rounded partner on which other Vodafone operators can now depend for their key location platform deliveries.”

Under the contract, Seeker delivered its SeekerZone™ solution which enables Vodafone to locate mobiles much more accurately and reliably, allowing Vodafone to offer a fixed-line product that runs on the subscriber’s mobile phone when it is at home or in a nominated location. Operators elsewhere that have launched location based billing products based on alternative, first generation Cell-ID systems have experienced severe revenue leakage because the location was not accurate or reliable enough. SeekerZone eliminates these issues saving some operators tens of millions of dollars in revenue every year.

Seeker’s technology extends beyond home zone solutions and can also be deployed to drive revenues from other location-sensitive services such as location based advertising and local mobile search.


About Seeker Wireless

Seeker Wireless has applied a radically new approach to determining the location of mobile devices without requiring a GPS in the handset. Seeker’s patented algorithms, 20 years ahead of current so called “triangulation” methods, yield significantly better accuracy and reliability and importantly deliver scalability that is simply not possible with other solutions.

SeekerZone™ enables location based billing for mobile network operators.

SeekerLocate™ permits cross-media players to deliver location based advertising and other location-sensitive services across multiple mobile networks.

Wireless Network

Wireless PAN

Wireless Personal Area Network (WPAN) is a type of wireless network that interconnects devices within a relatively small area, generally within reach of a person. For example, Bluetooth provides a WPAN for interconnecting a headset to a laptop. ZigBee also supports WPAN applications.


Wireless LAN

Wireless Local Area Network (WLAN) is similar to other wireless devices and uses radio instead of wires to transmit data back and forth between computers on the same network. Wireless LANs are standardized under the IEEE 802.11 series.

Screenshots of Wi-Fi Network connections in Microsoft Windows. Figure 1, left, shows that not all networks are encrypted (locked unless you have the code, or key), which means anyone in range can access them. Figures 2 and 3, middle and right, however, show that many networks are encrypted.
Wi-Fi: Wi-Fi is a commonly used wireless network in computer systems to enable connection to the internet or other machines that have Wi-Fi functionalities. Wi-Fi networks broadcast radio waves that can be picked up by Wi-Fi receivers attached to different computers or mobile phones.
Fixed Wireless Data: Fixed wireless data is a type of wireless data network that can be used to connect two or more buildings together to extend or share the network bandwidth without physically wiring the buildings together.


Wireless MAN

Wireless Metropolitan area networks are a type of wireless network that connects several Wireless LANs.
WiMAX is the term used to refer to wireless MANs and is covered in IEEE 802.16d/802.16e.


Mobile devices networks
Global System for Mobile Communications (GSM): The GSM network is divided into three major systems: the switching system, the base station system, and the operation and support system. The cell phone connects to the base system station which then connects to the operation and support station; it then connects to the switching station where the call is transferred to where it needs to go. GSM is the most common standard and is used for a majority of cell phones.[4]
Personal Communications Service (PCS): PCS is a radio band that can be used by mobile phones in North America. Sprint happened to be the first service to set up a PCS.
D-AMPS: D-AMPS, which stands for Digital Advanced Mobile Phone Service, is an upgraded version of AMPS but it is being phased out due to advancement in technology. The newer GSM networks are replacing the older system.


Uses

An embedded RouterBoard 112 with U.FL-RSMA pigtail and R52 mini PCI Wi-Fi card widely used by wireless Internet service providers (WISPs) in the Czech Republic.

Wireless networks have had a significant impact on the world as far back as World War II. Through the use of wireless networks, information could be sent overseas or behind enemy lines easily, efficiently and more reliably. Since then, wireless networks have continued to develop and their uses have grown significantly. Cellular phones are part of huge wireless network systems. People use these phones daily to communicate with one another. Sending information overseas is possible through wireless network systems using satellites and other signals to communicate across the world. Emergency services such as the police department utilize wireless networks to communicate important information quickly. People and businesses use wireless networks to send and share data quickly whether it be in a small office building or across the world.[5]

Another important use for wireless networks is as an inexpensive and rapid way to be connected to the Internet in countries and regions where the telecom infrastructure is poor or there is a lack of resources, as in most developing countries.

Compatibility issues also arise when dealing with wireless networks. Different components not made by the same company may not work together, or might require extra work to fix these issues. Wireless networks are typically slower than those that are directly connected through an Ethernet cable.

A wireless network is more vulnerable, because anyone can try to break into a network broadcasting a signal. Many networks offer WEP - Wired Equivalent Privacy - security systems which have been found to be vulnerable to intrusion. Though WEP does block some intruders, the security problems have caused some businesses to stick with wired networks until security can be improved. Another type of security for wireless networks is WPA - Wi-Fi Protected Access. WPA provides more security to wireless networks than a WEP security set up. The use of firewalls will help with security breaches which can help to fix security problems in some wireless networks that are more vulnerable.


Environmental concerns and health hazard

In recent times, there have been increased concerns and research linking usage of wireless communications with poor concentration, memory loss, nausea, premature senility and even cancer.[6] Questions of safety have been raised, citing that long term exposure to electromagnetic radiation of the sort emitted by wireless networks may someday prove to be dangerous.[7]

Next Microsoft OS: Touch and operate

CARLSBAD, CALIFORNIA: Microsoft Corp plans to give users of the next version of its Windows operating system touch screen controls as one option for controlling the software, its top executives said on Tuesday.

Bill Gates, chairman and chief executive Steve Ballmer showed off new Windows features based on software it calls "multi-touch" that will be part of Windows 7, the next version of Windows, which Ballmer said was due out in late 2009.

The ability to use touch to give users fingertip control of their screens could help revolutionize how computer desktops and mobile phones are controlled and would be an alternative to existing mice, keyboard and pen-based user controls.

During a joint interview that kicked off the Wall Street Journal's three-day 'All Things Digital' conference, an annual gathering of the computer industry elite taking place north of San Diego, Ballmer said touch screen controls was one example of how Microsoft would improve on existing Windows software.

Microsoft is seeking to one-up Apple Inc, which made touch-screen software central to the success of its iPhone mobile device, which combines computer, phone and Web features and has sold around 6 million units in its first 11 months.

After more than a decade of slow development, Gates said new ways of interacting with computers other than keyboards and mice have matured to the point where they are ready to go mainstream.

"We are at an interesting juncture where almost all of the interaction is with the computer and mouse, today, and, over the years to come, the role of speech, vision, ink, all of those will become huge," Gates said.

He was referring to technologies that gives users the ability to control computers with voice commands, detect and sort different kinds of images and use electronic ink instead of typing for computer input.

Surface

Multi-touch software builds on existing capabilities Microsoft has introduced in recent years including Surface, for interacting with large tabletop computer displays, TouchWall for mounted screens and Tablet PCs for touch-screen notebooks.

In a demonstration of touch-screen capabilities to be offered in Windows 7, Microsoft showed a new application called "Touchable Paint" that lets a user paint with their fingers, as well as software to organize photos or navigate maps by touch.

"It is not about complete replacement of the mouse," Julie Larson-Green, Microsoft's corporate vice president in charge of Windows Experience Program Management, said in a first-time demonstration of multi-touch features to run inside Windows 7.

Ballmer said Microsoft is trying to learn from the reaction to Windows Vista, the latest version of its operating system, which was introduced in January 2007 but faced initial criticism for being incompatible with many older applications.

He said Microsoft has sold 150 million copies of Vista, up from 140 million the company reported it had sold a month ago.

"When you read the customer research, the No. 1 people found jarring is that we changed the user interface," Ballmer said. "People take a while to get used to it."

He said Microsoft had learned lessons about making dramatic changes in the way users interact with new versions of Windows. Conference co-host Walter Mossberg asked Ballmer whether Microsoft was done changing the user interface.

"We will polish it," Ballmer replied. "We will change it, but there are ways to change it and there are times to do it."

Vista followed five years after the previous Windows upgrade and was beset by delays due to the complexity of updating a piece of software with some 50 million lines of code that runs on more than 90 percent of the world's computers.

After the problems of releasing Vista in a timely manner, Ballmer pledged to never again wait so long between releases of its Windows operating system. Microsoft has said it expected to release the new operating system code-named Windows 7 around three years after the early 2007 release of Windows Vista.

Ballmer acknowledged that Microsoft considered Apple a formidable competitor. But he said the two companies' audiences were vastly different in scale, with Apple supplying around 10 million computers this year versus the roughly 290 million machines which PC makers will sell running Microsoft Windows.

Orkut-aided credit card fraud busted

HYDERABAD, INDIA: A new case of credit card fraud has surfaced in Hyderabad with social networking sites playing a vital part in the crime.

The group stealing credit card numbers created communities on Orkut announcing heavily discounted flight tickets.

The discounts were offered to travel agents with about 30-40 per cent commission. But tickets bought were double paid first through the stolen credit card and secondly through the actual passenger.

Hyderabad's Central Crime Station (CCS) has arrested one person from Vishakapatnam following a complaint from Hyderabad.

"The gang has a database of stolen credit card numbers. We were intimated by a person who got an SMS alert from his bank on usage of his credit card to book destinations that he never traveled," said J Anyonya, investigating officer of the case at Central Crime Station.

The communities created at Orkut were under several pseudonyms changed at regular intervals.

"The person using these Orkut communities used laptops with data cards. Changing locations of the URL has confirmed this," said Anyonya.

To gain confidence of small time agents, payments were collected at a different account number after the passenger reached the destination.

The CCS took the help of the cyber crime cell in Hyderabad and is on the look out for other key persons such as the one caught in Vishakapatanam.

Cyber crime on rise

The revelation however, is not even the tip of the iceberg. Cyber crime in Hyderabad city alone runs into thousands in a month say experts in the field. "Most cyber crime goes unreported as people either go back to banks and are simply too fed up to explain this crime to police who more often than not has no idea how this theft works," said Zaki Qureshey, founder and CEO E2-Labs, an Ethical Hacking school in Hyderabad.

Cyber crimes especially involving credit cards are on the rise and spare no one including the who's who of tinsel town. It is the financial institution through which such crimes come out in the open, but a lot from frivolous to very serious ones go unnoticed say experts.

"We not have laws to govern networking sites such Orkut. The headquarters of this is outside the country thus not under the purview of Indian government. India is very different from countries, which have mature cyber laws. In our situation social networking should not be allowed at all," said Qureshey.

Increasing of cyber crime cells in the city and educating the police about technology and inclusion of other civil technical experts in the process will help in resolving such crimes better, he added.

HP wants to buy EDS to take on IBM

PALO ALTO, USA: After gobbling up Compaq for $25 billion in 2001, IT giant Hewlett-Packard is looking at Electronic Data Systems (EDS) Corp for a possible buy-out.

Media reports puts the deal size could be in the range of $12 billion to $13 billion.

HP and EDS confirmed that they are engaged in advanced discussions on a possible business combination involving the two companies.

"There can be no assurances that an agreement will be reached or that a transaction will be consummated. HP does not intend to comment further until an agreement is reached or discussions are terminated," HP said in a statement.

Buying Plano, Texas-based $22.1 billion EDS would give HP more tools to compete against IBM in the lucrative field of technology consulting and customer support.

Revenue (or Income) from an Ad

= Clickthrough value of the ad * Payout Rate * Clickthrough rate of the Ad * Webpage traffic * Frequency of Ad

Example :

Clickthrough Value = 30 cents or $0.30 (The advertiser pays 30 cents per click for the Ad, to Google)

Payout Rate = 50% or 0.5 (This is an assumption based on what many experts believe to be the current payout rate for most deals)

Clickthrough rate of the Ad = the ad is displayed 100 times within the day and clicked by 9 people = the clickthrough rate would be 0.09

Webpage traffic = 150 visitors during the days

Frequency of Ad = 100

The Income per day from a single ad would be = 0.30 * 0.5 * 0.09 * 150 * 100
= $202.5 / day.

Google boys have grown up, says CEO

Google to launch new YouTube products soon

MOUNTAIN VIEW, USA: Google Inc expects to launch new products for its YouTube web video service in the next few months and sees reason for closer cooperation with Yahoo Inc, Google Chief Executive Eric Schmidt said on Thursday.

Schmidt has said getting the video sharing site to make money is the web search company's top priority for the year. He did not give details of the products, however, and they are not even in initial, or beta, testing.

At the company's annual shareholder meeting, Google co-founder Sergey Brin said YouTube and DoubleClick, an online advertising company bought by Google earlier this year for $3.1 billion, are still small businesses compared with its core search and advertising business.

"They both have potential, but for it to be a sizable part of our revenue, you're going to have to wait at least a couple of years," said Brin in response to a question about when those acquisitions would make a significant contribution to the company's bottom line.

Google bought YouTube for $1.6 billion in 2006.

The web search leader played a large role in the takeover battle between Microsoft Corp and Yahoo. During a two-week test, it sold search advertisements on rival Yahoo last month as part of Yahoo's attempt to find an alternative option to Microsoft's offer.

Schmidt said the trial run provided good reason for the companies to discuss cooperation, but there was no deal yet.

"We view the test as successful," he told reporters before the web company's annual meeting. "That's a good basis to talk to Yahoo some more."

The Google CEO, speaking later at the shareholder meeting, said the company will continue to growth faster outside of its home market.

Google generated 51 per cent of its revenue outside the US in the March quarter, but Schmidt said he expects that figure to grow over time.

Without giving a specific time frame, Schmidt said he expects 65 per cent of Google's revenue to come from abroad. Eventually, non-US
revenue could be even higher.

Google co-founders Brin and Larry Page also fielded a request from one shareholder who asked the pair not to split the company's stock, which closed at $583 on the Nasdaq.

"I think that's the first time we've had that request," Page said with a chuckle.

Brin played the straight man: "We have had no problem honoring that thus far and I don't expect that anything will change in that respect."

Global Warming: The Cold, Hard Facts?

Global Warming, as we think we know it, doesn't exist. And I am not the only one trying to make people open up their eyes and see the truth. But few listen, despite the fact that I was one of the first Canadian Ph.Ds. in Climatology and I have an extensive background in climatology, especially the reconstruction of past climates and the impact of climate change on human history and the human condition. Few listen, even though I have a Ph.D, (Doctor of Science) from the University of London, England and was a climatology professor at the University of Winnipeg. For some reason (actually for many), the World is not listening. Here is why.

What would happen if tomorrow we were told that, after all, the Earth is flat? It would probably be the most important piece of news in the media and would generate a lot of debate. So why is it that when scientists who have studied the Global Warming phenomenon for years say that humans are not the cause nobody listens? Why does no one acknowledge that the Emperor has no clothes on?

Believe it or not, Global Warming is not due to human contribution of Carbon Dioxide (CO2). This in fact is the greatest deception in the history of science. We are wasting time, energy and trillions of dollars while creating unnecessary fear and consternation over an issue with no scientific justification. For example, Environment Canada brags about spending $3.7 billion in the last five years dealing with climate change almost all on propaganda trying to defend an indefensible scientific position while at the same time closing weather stations and failing to meet legislated pollution targets.

No sensible person seeks conflict, especially with governments, but if we don't pursue the truth, we are lost as individuals and as a society. That is why I insist on saying that there is no evidence that we are, or could ever cause global climate change. And, recently, Yuri A. Izrael, Vice President of the United Nations sponsored Intergovernmental Panel on Climate Change (IPCC) confirmed this statement. So how has the world come to believe that something is wrong?

Maybe for the same reason we believed, 30 years ago, that global cooling was the biggest threat: a matter of faith. "It is a cold fact: the Global Cooling presents humankind with the most important social, political, and adaptive challenge we have had to deal with for ten thousand years. Your stake in the decisions we make concerning it is of ultimate importance; the survival of ourselves, our children, our species," wrote Lowell Ponte in 1976.

I was as opposed to the threats of impending doom global cooling engendered as I am to the threats made about Global Warming. Let me stress I am not denying the phenomenon has occurred. The world has warmed since 1680, the nadir of a cool period called the Little Ice Age (LIA) that has generally continued to the present. These climate changes are well within natural variability and explained quite easily by changes in the sun. But there is nothing unusual going on.

Since I obtained my doctorate in climatology from the University of London, Queen Mary College, England my career has spanned two climate cycles. Temperatures declined from 1940 to 1980 and in the early 1970's global cooling became the consensus. This proves that consensus is not a scientific fact. By the 1990's temperatures appeared to have reversed and Global Warming became the consensus. It appears I'll witness another cycle before retiring, as the major mechanisms and the global temperature trends now indicate a cooling.

No doubt passive acceptance yields less stress, fewer personal attacks and makes career progress easier. What I have experienced in my personal life during the last years makes me understand why most people choose not to speak out; job security and fear of reprisals. Even in University, where free speech and challenge to prevailing wisdoms are supposedly encouraged, academics remain silent.

I once received a three page letter that my lawyer defined as libellous, from an academic colleague, saying I had no right to say what I was saying, especially in public lectures. Sadly, my experience is that universities are the most dogmatic and oppressive places in our society. This becomes progressively worse as they receive more and more funding from governments that demand a particular viewpoint.

In another instance, I was accused by Canadian environmentalist David Suzuki of being paid by oil companies. That is a lie. Apparently he thinks if the fossil fuel companies pay you have an agenda. So if Greenpeace, Sierra Club or governments pay there is no agenda and only truth and enlightenment?

Personal attacks are difficult and shouldn't occur in a debate in a civilized society. I can only consider them from what they imply. They usually indicate a person or group is losing the debate. In this case, they also indicate how political the entire Global Warming debate has become. Both underline the lack of or even contradictory nature of the evidence.

I am not alone in this journey against the prevalent myth. Several well-known names have also raised their voices. Michael Crichton, the scientist, writer and filmmaker is one of them. In his latest book, "State of Fear" he takes time to explain, often in surprising detail, the flawed science behind Global Warming and other imagined environmental crises.

Another cry in the wildenerness is Richard Lindzen's. He is an atmospheric physicist and a professor of meteorology at MIT, renowned for his research in dynamic meteorology - especially atmospheric waves. He is also a member of the National Academy of Sciences and has held positions at the University of Chicago, Harvard University and MIT. Linzen frequently speaks out against the notion that significant Global Warming is caused by humans. Yet nobody seems to listen.

I think it may be because most people don't understand the scientific method which Thomas Kuhn so skilfully and briefly set out in his book "The Structure of Scientific Revolutions." A scientist makes certain assumptions and then produces a theory which is only as valid as the assumptions. The theory of Global Warming assumes that CO2 is an atmospheric greenhouse gas and as it increases temperatures rise. It was then theorized that since humans were producing more CO2 than before, the temperature would inevitably rise. The theory was accepted before testing had started, and effectively became a law.

As Lindzen said many years ago: "the consensus was reached before the research had even begun." Now, any scientist who dares to question the prevailing wisdom is marginalized and called a sceptic, when in fact they are simply being good scientists. This has reached frightening levels with these scientists now being called climate change denier with all the holocaust connotations of that word. The normal scientific method is effectively being thwarted.

Meanwhile, politicians are being listened to, even though most of them have no knowledge or understanding of science, especially the science of climate and climate change. Hence, they are in no position to question a policy on climate change when it threatens the entire planet. Moreover, using fear and creating hysteria makes it very difficult to make calm rational decisions about issues needing attention.

Until you have challenged the prevailing wisdom you have no idea how nasty people can be. Until you have re-examined any issue in an attempt to find out all the information, you cannot know how much misinformation exists in the supposed age of information.

I was greatly influenced several years ago by Aaron Wildavsky's book "Yes, but is it true?" The author taught political science at a New York University and realized how science was being influenced by and apparently misused by politics. He gave his graduate students an assignment to pursue the science behind a policy generated by a highly publicised environmental concern. To his and their surprise they found there was little scientific evidence, consensus and justification for the policy. You only realize the extent to which Wildavsky's findings occur when you ask the question he posed. Wildavsky's students did it in the safety of academia and with the excuse that it was an assignment. I have learned it is a difficult question to ask in the real world, however I firmly believe it is the most important question to ask if we are to advance in the right direction.

HP Discovers Potential "God Particle" of Electronics

From the Sounds Cool dept.:
...today, Hewlett Packard announced a new electrical component born of theoretical physics. The device, a nanoscale component called a "memristor," requires no power to retain data, which it can store more densely than a hard drive and access about as fast as a computer’s RAM memory—potentially allowing it to replace both components in the future.

Memristors can function in either a digital mode, in which a memory cell is “on” or “off,” or in analog mode, in which each cell holds some value in between. These values grow every time the cell receives an electrical signal, mimicking the way neurons in the brain build stronger memories the more they are stimulated.

Top 10 Brains

1. The largest brain belongs to the sperm whale: 7 kg (17.5 kg). The blue whale, the largest animal on the planet, being twice longer and thrice heavier, has a brain weighing 5 kg (12.5 pounds).

2. Human brain has an average weight of 2.7 pounds (1.2 kg), variations between 1.1 and 1.4 kg being considered normal. Our brain represents 2% of our weight, the largest brain
in the animal world compared to the body size.

3. The brain of the men is, on average, 100 grams (0.3 pounds) heavier than that of the women.

4. The largest brain of a terrestrial animal is that of the elephant: 10.5 pounds (4.78 kg). Still, the brain of the elephant makes less than 0.1% of its body weight.

5. Amongst our relatives, the primates, apes have the largest brains. The mountain gorilla (Gorilla gorilla beringei) has a 0.95 pounds (430 g) brain. Still, that of the chimpanzee is larger compared to its body size: 0.77 pounds (350 g) (a chimpanzee male is 2.5-3 times lighter than a gorilla male).

The smallest primate brain is detained by the mouse lemur (Microcebus murinus) of Madagascar: 0.004 pounds (2 g) (this is also the smallest primate in the world).

6. The largest brain of a carnivore mammal is that of the walrus (Odobenus rosmarus): 2.4 pounds (1.1 kg).

7. Domesticated animals have smaller brains than those of their wild forebears. At a similar body weight, the brain of the domestic cat (with an average value of 0.06 pounds or 30 grams) is 23.9 % lighter than that of the wild cat, the brain of the dog is 29 % lighter than that of the wolf, and the brain of the pig is 34 % lighter than that of the wild boar.

8. The octopus is known to be the most intelligent invertebrate. Its brain is made by the largest neurons (brain cells) found in nature.

An octopus brain is formed by 500 million large neurons (while the human brain is made of roughly 100 billion smaller neurons), but the intelligence of this aquatic creature is comparable with that of the apes.

9. After humans, the nature's relatively largest brain is that of the dolphin: 2 kg. A dolphin weighing 120 kg (280 pounds) has a 1.7 kg (4 pounds) brain; compared to its size, this is almost thrice than a chimp.

10. Amongst vertebrates, the smallest brain in relation with the body size seems to have belonged to a dinosaur: Stegosaurus was 6 m (20 ft) long and weighed 2 tons. Its brain was just the size of a walnut! To compensate this, the spine presented a second "brain" in the pelvic area.

Advanced Micro Devices' President and Chief Operating Officer Dirk Meyer confirmed, during the last week’s conference call, that the chip manufacturer plans to release its next CPU
architecture, also known as Bulldozer, in 2009.

The multi-core processor will come straight in the 45-nanometer flavor. However, the 45-nanometer chips will be available only for a short period of time, as AMD will make the transition to the 32-nanometer CPU micro-architecture right after Bulldozer is introduced.

AMD will start sampling the Bulldozer chip in late 2009, but the chip will not be publicly available in the 45-nanometer technology. This means that there is a long way ahead until it finally appears in retail systems, given the fact that AMD has not even started producing chips at the 45-nanometer node.

The slow transition is mostly due to the fact that AMD's Fab 36 is currently manufacturing the company's Athlon, Phenom, Sempron and Turion families of processors, and replacing the whole technology will likely affect the manufacturing operations.

The Bulldozer chip will come as a 16-core silicon, touted by the company as the first substantially new CPU core since the original Athlon 64 processor. Moreover, the new chip will be built from scratch and will offer a solid foundation for the company's upcoming architectures. The chip is aimed at the "Sandtiger" server and workstation platforms that are expected to arrive in mid-2009.

However, the recent wave of layoffs that hit the chip manufacturer's headquarters are likely to make the company miss its deadlines. According to previous reports, the Austin and California offices are the most affected locations. While the Austin facility is working on the Barcelona and Phenom families, the Bulldozer chip is exclusively baked in California, and the layoffs will leave the company with less workforce available for the project.

Updated Web Browsers: Which One Works Best?

Back when the earliest programs for viewing Web content simply browsed flat pages of images and text, the name browser truly fit the software.

But yesterday's amateur pages have evolved into dynamic, content-rich portals and powerful online programs. For many online habitués, the do-it-all browser has become a PC's single most important program.

Recognizing that fact, Apple's Safari, Microsoft's Internet Explorer, and Mozilla's Firefox are battling to win the nod as your browser of choice. So which one should you use--Safari 3.1, Firefox 3, or Internet Explorer 8?

Apple's latest offering, Safari 3.1, preserves the company's signature focus on clean design and smooth usability, but it lacks any phishing or malware filters.

For its part, Mozilla should have applied the finishing touches to Firefox 3 by the time you read this (I tested the feature-complete beta 5 release). From under-the-hood memory improvements to a major reworking for bookmarks, version 3 represents a big step forward.

Whereas the new Firefox and Safari browsers are ready to roll, Microsoft's early beta of Internet Explorer 8 remains a work in progress. Bugs and rough edges are to be expected in a first beta intended for developers and testers. But IE 8 beta 1 provides a glimpse of new features such as WebSlices (which let sites create widgety snippets of information that you can view by clicking a bookmark button) and Activities (which add right-click menu options for looking up selected text and pages on map, translation and other sites) that will distinguish the browser Microsoft eventually releases.

Firefox, IE, and Safari are the three most popular browsers, according to Internet usage statistics, but they aren't the only ones available. So I also took a separate look at two worthwhile, free programs--Flock and Opera.

Open Source Licenses

I've been working on a small piece of software that I plan on releasing with an open source license. There are so many licenses out there that I often forget what differentiates them. So I put together a small chart outlining some of the differences.

The recent debacle with Ray Camden's blog software is a good example of what can happen when you don't have a clear license. Some open source licenses require derivatives to be open source. Other licenses allow derivatives to be sold commercially, or sub-licensed (this is what Apple does with Darwin - which is based on BSD).

I picked out the some of the most popular licenses to compare. A full text copy of each license may be found at the Open Source Institute.

x = yes

Are there any other points to compare?
