SATYAM SAGA SHOWS HOLES IN INDIA CORPORATE GOVERNANCE

Just three months ago, India's fourth-largest software services exporter, Satyam Computer Services received a Golden Peacock award from a group of Indian directors for excellence in corporate governance.

Now its board is in turmoil and its shares have plunged after a botched attempt to buy two infrastructure firms in which management held stakes, sparking concerns about conflicts of interest and a lack of transparency.

Analysts say the saga exposes serious shortfalls in corporate India that must be addressed to ensure its credibility in an increasingly globalised and competitive world.

Four independent directors have resigned from the board of Satyam since the scandal erupted. But that does not fix the problem, said Premchand Palety, director of the Centre for Forecasting and Research in Delhi.

"Independent directors are supposed to be the watchdogs, the ones responsible for safeguarding the interests of minority shareholders. They clearly failed in their duty," he said.

Satyam says it adhered to corporate governance rules, appointing the requisite number of independent directors with excellent credentials, including the dean of a top business school in its hometown of Hyderabad and a professor at Harvard business school.

But there are concerns that some directors may be too close to Satyam's chairman to be considered truly independent, and all of them failed to ask tough questions about the now controversial infrastructure deals, Palety said.

"If Satyam's board was convinced about the merits of acquiring (the two firms), then good corporate governance demanded that it should have taken into confidence at least the major institutional shareholders," he said.

Even though the company aborted the plan, the damage was done: New York-listed Satyam's shares have plunged by a third since it first announced plans to acquire two sister firms for $1.6 billion and then abandoned the deal two weeks ago.

Satyam's board will meet on Jan 10 to consider more options to improve shareholder value and corporate governance.

DIFFERENCE BETWEEN DUAL CORE AND CORE 2 DUO

The Core 2 Duo is Intel's second generation (Hence, Core 2) processor made for desktops and laptops designed from the ground up to be fast while not consuming nearly as much power as previous CPUs, Dual core is simply a generic term referring to any processor package with two physical CPUs in one.

Dual core and Core2 Duo both use 2 cores to process instructions..... good.... ok... but what's the difference then...

Well... the main difference is in the cache memory they use.....
The Dual Core processors use single cache shared between the 2 cores... plus, the size of this cache memory is usually less as compared to Core2 Duo ones (typically in size of 128 KB to around 512 Kb or 1 MB)......

On the other side Core 2 Duo processors also use 2 cores but they have dedicated cache memory assigned to each of the core. so in effect there are two cache memories (note - in case if you don't know what exactly cache memory is - its a static memory - Static RAM - which is costly - and charged per KB size - because they are embedded into your processors.... and your processor stores instruction set into these cores and also info of frequently accessed memory locations so that it doesn't need to go to your main memory - RAM - on motherboard - every time and search indexes to get these locations. The result is - your access time is greatly reduced.. ok.. enough of info... lets get back to main topic)... so, the more cache your processor has got, the more costly will it be and more info can it store and faster will it become.... coming back to Core 2 Duo processors.... the cache size is typically 1 MB to up to 4 / 6 / 8 /12 Mb of size. so if a core 2 duo processor config states 4 Mb of cache, then effectively your 2 cores will use 2 Mb each... now you can make out the difference in speed between a dual core using 512 cache and a Core 2 Duo using 4 Mb of cache... and the same reason why core 2 duo processors are costly and more faster (about 40 %) than the dual core ones...

Finally... to summarize, dual core procs (less cache size and that too shared cache between two cores) are strip in version of Core 2 Duo procs (more cache size and independant cache between each of the two cores), which make Core 2 Duo procs costlier and faster than Dual Core procs... so the winner is Core 2 Duo (and its comes with a price...)

PAK HACKER ATTACKS E RLYS SITE, THREATENS CYBER WAR ON INDIA

In the first instance of cyber attack on Indian government websites, the attack on Eastern Railways site on Wednesday popped open vulnerability of government websites in the country.

While Eastern Railway took almost two and half hours to restore the site to normalcy, visitors to the site continued to be attacked by Trojan virus. ER officials could only primarily trace the roots to Toronto in Canada after repeated top-brass meetings all through the day.

As spotted by FE in the morning, the official site of the Eastern Railway-www.eastern railway.gov.in—was hacked on Wednesday. When opened, the scroll on the site— which normally consists of official announcements—had unusual notes. The first note read: "Cyber war has been declared on Indian cyberspace by Whackerz- Pakistan (24 Dec-2008)." This was followed by two other notes: "Indians hit hard by Zaid Hamid" and "We are f**ked up Indians. You are hacked."

When clicked, the scroll opened into a new window which claimed that 'Mianwalian of Whackerz" has hacked the site in response to the air violation of Pakistan. It also claimed that it will continue to hack more Indian military and government sites. The threat note also claimed that servers of Indian financial institutions will also be hacked with the help of the group's members working in computer departments of "foreign companies". Data belonging to "Indian nationals (only Hindus)" will be destroyed eventually, it added.

Another threat note asked the visitors of the website to watch the real Indian conspiracy in Mumbai attacks on the website-www.brasstacks.pk. Brasstacks claims to be "a unique Pakistani think tank devoted to the study of regional and global political events and their implications for Pakistan's security and interests." The note ended with the slogan "Long live Pakistan".

The third note, which showed the hackers' apathy towards India, Israel and USA, challenged Indians to save their 'motherland' from turning into pieces.

When contacted, ER officials seemed unaware of the entire incident and the site remained as it is for almost an hour, till 11.40am, after which ER blocked it. The website resumed to normalcy after 12, when the threat notes in the scroll as well as in the news and events section were removed.

"Our sites have cyber security certificate from US-based Thawte," said an ER official. "We have informed the service provider and will get a detailed response from them only after 24 hours," he added.

According to a cyber security expert, similar attacks can be done through SQL injection method. In case of a SQL injection attack, webpages with active content like feedback forms are used. Attackers can write malicious commands in the forms through a rich text format and get control over the database of the target site.

VOLVO TO UNVEIL WORLD'S FIRST ACCIDENT-PROOF CAR NEXT MONTH

Car giant Volvo is set to unveil its first ever "accident-proof car", which will drive itself in traffic by using radar to control the distance.

The Swedish manufacturer will unveil Volvo S60 with automatic brakes at the next month's Detroit motor show. It will go on the market in 2010.

"This technology helps us take an important step towards our long-term vision of designing cars that should not crash," the Telegraph quoted Thomas Broberg, the company's safety specialist as saying.

"Our aim for 2020 is that no one should be killed or injured in a Volvo car," he added.

The car can stop itself upon sensing that a collision is about to happen either a car or a pedestrian, even when travelling at low speeds.

It will feature a sophisticated cruise control system designed to automatically maintain a safe distance from the car in front.

It works with the help of a radar unit fitted in the car's grille, which not only detects what is in front of the vehicle, but how fast it is moving.

When the car believes that there is an imminent threat of a collision, a light flashes on a windscreen display in front of the driver at the same time along with an audible warning, the brakes are applied automatically.

10 Technologies That Will Transform Your Life

1) Digital Libraries

Having total connectivity is pointless if all you get is the latest gossip about Paris Hilton. But the digitization of mankind's accumulated works proceeds apace. All of MIT's courses are now online, for instance, and, if you haven't done so, check out Google Book Search. The time will come when any straightforward factual question can be answered immediately, online. But, alas, those are always the easy questions.



2) Gene Therapy and/or Stem Cells

A lot of maladies actually involve inherited conditions–they're in your genes, in other words. But scientists are working to change those genes and trick defective cells into growing correctly. Perhaps, someday, birth defects will be as treatable as pneumonia.






3) Pervasive Wireless Internet

WiMAX, 3G, 4G, etc., all point to a pervasive wireless Internet, where being on-line everywhere, all the time, will be routine. That implies the possibility of full connectivity between any two random devices. Want to check your burglar alarm from your cell phone? It'll be easy. Unjacking to get away and relax, however, may not be so easy.




4) Mobile Robots

The recent DARPA challenge (where robot cars navigated through suburban traffic) hints at what might come. Why drive to the deli to pick up your order when you can just send your car? We may see convoys of robot trucks on the highways. Admittedly, they'll probably have more initial acceptance in warehouses, handling pick-and-pull chores.




5) Better, Cheaper Solar Cells

The cost of photovoltaic cells (that turn sunlight into electricity) are coming down. In less than ten years the cost of solar energy could be at parity with the cost of electricity from the grid, and solar cells could be standard features in new residential construction. Your house could power itself about a third of the time. (Science can't do much about night and bad weather.)




6) Location-Based Computing

Instead of clicking an icon on a browser screen, you can walk outside, point your cell phone at an actual three-dimensional thing (presumably, a building that houses a business), click the phone, and get information about (or jump to the Web site of) whatever you were pointing at. As well as servers with Internet address, there will be servers with geographic coordinates.




7) Desktop 3-D Printing

Instead of going to the store for your next gadget, you might download a design of your choosing and generate it in your desktop 3-D printer. The next step will be to design your own gadgets, post the designs, and sell them, etc. Toys, kitchenware, and decorative household items should be fair game, at least. Cottage industry, here we come!






8) Moore's Law Upheld

The law, stated by Intel cofounder Gordon Moore in 1965, implies that available computer power can be expected to double every other year. For at least two decades pundits have been pointing out barriers to the law's fulfillment, and the chip industry has been smashing those barriers. Currently they can't agree if the law has a couple of more decades of life left, or 600 years. Either way, in terms of available computing power, it's clear that we ain't seen nothing yet.


9) Therapeutic Cloning

Forget the stories about generating identical copies of a particular sheep or person. The whole idea behind cloning all along has been to grow replacement organs or tissue in a vat, which the body would see no reason to reject. Cancerous or damaged organs could be replaced by new, disease-free clones of themselves.





10) The Hydrogen Economy

Instead of guzzling imported oil (and being at the mercy of oil suppliers) we could turn water into hydrogen and burn that (or use to charge fuel cells.) Meanwhile, the only byproduct of the combustion of hydrogen is ... more water! However, hydrogen storage remains a thorny issue, due to its low density, and hydrogen may end up being only one of many interlocking components that replace the current oil economy.
