EXTRA SECOND (LEAP SECOND) ADDED TO 2008

Those eager to put 2008 behind them will have to hold their good-byes for just a moment this New Year's Eve.

The world's official timekeepers have added a "leap second" to the last day of the year on Wednesday, to help match clocks to the Earth's slowing spin on its axis, which takes place at ever-changing rates affected by tides and other factors.

The U.S. Naval Observatory, keeper of the Pentagon's master clock, said it would add the extra second on Wednesday in coordination with the world's atomic clocks at 23 hours, 59 minutes and 59 seconds Coordinated Universal Time, or UTC.

That corresponds to 6:59:59 p.m. EST (23:59:59 GMT), when an extra second will tick by -- the 24th to be added to UTC since 1972, when the practice began.

UTC is the time scale kept by highly precise atomic clocks around the world, accurate to about a billionth of a second per day, the Naval Observatory says. For those with a need for precision timing, it has replaced Greenwich Mean Time, or GMT.

The decision to add or remove a second is the responsibility of the International Earth Rotation and Reference Systems Service, based on its monitoring of the Earth's rotation.

The goal is to make sure clocks vary from the Earth's rotational time by no more than 0.9 seconds before an adjustment. That keeps UTC in sync with the position of the sun above the Earth.

Mechanisms such as the Internet-based Network Time Protocol and the satellite-based Global Positioning System depend on precision timing.

The first leap second was introduced into UTC on June 30, 1972. The last was added on December 31, 2005.

They have been added at intervals ranging from six months to seven years, Daniel Gambis, head of the IERS Earth Orientation Center at the Observatoire de Paris, wrote in an explanatory piece this month (http://hpiers.obspm.fr/eop-pc/).

Among the reasons for Earth's slowing whirl on its axis are the braking action of tides, snow or the lack of it at the polar ice caps, solar wind, space dust and magnetic storms, according to the U.S. Commerce Department's National Institute of Standards and Technology, another timekeeper.

By contrast, a leap day, February 29, occurs once every four years because a complete turn around the sun -- our year with all its seasons -- takes about 365 days and six hours.

In 1970, an international agreement established two time scales: one based on the Earth's rotation and another on highly accurate atomic clocks.

The U.S. Naval Observatory's master clock is based on a system that now includes 50 atomic clocks, 36 based on the element cesium and 14 known as hydrogen masers.

With the Earth's rotation gradually slowing, the periodic insertion of a leap second into the atomic time scale is needed to keep the two systems within a second of each other.

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.
