The Y2K bug

Hi friends,
As you all know there's a new in front of us... It is gonna be 10 years after the millennium threat (the Y2K threat)...the great milestone in computer's history! Let us recall it.

The Year 2000 problem (also known as the Y2K problem, the millennium bug, the Y2K bug, or simply Y2K) was a notable problem for both digital (computer-related) and non-digital documentation and data storage situations which resulted from the practice of abbreviating a four-digit year to two digits.
In computer program design, the practice of representing the year with two digits becomes problematic with logical error(s) arising upon "rollover" from x99 to x00. This has caused some date-related processing to operate incorrectly for dates and times on and after January 1, 2000 and on other critical dates which were billed "event horizons". Without corrective action, it was suggested that long-working systems would break down when the "...97, 98, 99, 00..." ascending numbering assumption suddenly became invalid. Companies and organizations worldwide checked, fixed, and upgraded their computer systems.
While no globally significant computer failures occurred when the clocks rolled over into 2000, preparation for the Y2K bug had a significant effect on the computer industry. Countries that spent very little on tackling the Y2K bug (including Italy and South Korea) experienced as few problems as those that spent much more (such as the United Kingdom and the United States), causing some to question whether the absence of computer failures was the result of the preparation undertaken or whether the significance of the problem had been overstated.
Many banks have responded to the Y2K problem by forcing full 4-digit year entries on cheque forms, which helps to prevent the error from occurring in accounting environments.

Background

Y2K was the common abbreviation for the year 2000 software problem. The abbreviation combines the letter Y for "year", and k for the Greek prefix kilo meaning 1000; hence, 2K signifies 2000. It was also named the Millennium Bug because it was associated with the popular, rather than literal, roll-over of the millennium, despite the fact that the bug could have occurred at the end of any ordinary century.

The Year 2000 problem was the subject of the early book, "Computers in Crisis" by Jerome and Marilyn Murray (Petrocelli, 1984; reissued by McGraw-Hill under the title "The Year 2000 Computing Crisis" in 1996). The first recorded mention of the Year 2000 Problem on a Usenetnewsgroup occurred Saturday, January 19, 1985 by Usenet poster Spencer Bolles.

The acronym Y2K has been attributed to David Eddy, a Massachusetts programmer, in an e-mail sent on June 12, 1995. He later said, "People were calling it CDC (Century Date Change), FADL (Faulty Date Logic) and other names."

Many computer programs stored years with only two digits, for example, 1980 would be stored as 80. Some such programs could not distinguish between the year 2000 and the year 1900. Other programs would try to represent the year 2000 as 19100. This could cause a complete failure and cause date comparisons to produce incorrect results. Some embedded systems, making use of similar date logic, were expected to fail and cause utilities and other crucial infrastructure to fail.

Some warnings of what would happen if nothing were done were particularly dire:

The Y2K problem is the electronic equivalent of the El Niño and there will be nasty surprises around the globe. — John Hamre, Deputy Secretary of Defense 

Special committees were set up by governments to monitor remedial work and contingency planning, particularly by crucial infrastructures such as telecommunications, utilities and the like, to ensure that the most critical services had fixed their own problems and were prepared for problems with others. While some commentators and experts argued that the coverage of the bug largely amounted to scaremongering, it was only the safe passing of the main "event horizon" itself, January 1, 2000, that fully quelled public fears. Some experts who argued that scaremongering was occurring, such as Ross Anderson, Professor of Security Engineering at the University of Cambridge Computer Laboratory, have since claimed that despite sending out hundreds of press releases about research results suggesting that the bug was not likely to be as big a problem as some had suggested, they were largely ignored by the media.

Programming problem

The practice of using two-digit dates for convenience predates computers.

However there were no major problems reported due to this bug....... tribute to brilliant programmers who saved us!

How to show and use the Shortcuts keys in Word 2007?

In Word 2007, most of the shortcut keys are same from the earlier versions such as Word 2000 and Word 2003. But the interesting thing in Word 2007 is that, Microsoft provides a new look or system for these shortcuts keys. In earlier Word versions, you must be memorized to use the shortcuts keys such as (CTRL + B" to make letters bold and "CTRL + I" to make letters italic). But now do not require planned memorization in latest Word 2007 version. There is a fast, simple, and visual way to find out what you need to press.

Now by pressing the "ALT" button and many options or keyboard shortcuts (containing letters or numbers) will be appear on top of the toolbar buttons.

You will see here, For Example:

Alt-F = Office Button

Alt-1 = Save

Alt-2 = Undo

Alt-3 = Redo

Alt-H = Home

Alt-N = Insert tab

Alt-P = Page Layout tab

Alt-S = References tab

Alt-M = Mailings tab

Alt-R =Review tab

Alt-V =View tab

Alt-L = Developer tab

To get the shortcut keys for earlier versions of office please go through our archives.

Twitter and Facebook for the Computer Shy

How do you use social networks like Twitter and Facebook if you are computer shy or don’t have access to the Internet?

Well, you can use a mobile phone to post updates without a computer but this woman is using something that most of us can’t even imagine — see uses a pen to write her tweets on a piece of paper and then send them to Twitter using a fax machine.

Hard to believe? Watch this news story:


The woman, whose Twitter handle is @dorothy_celery, uses a service from Celery that lets people send and receive email messages through a fax machine without requiring a computer or an Internet connection. Other than email, Celery now works with Twitter and Facebook as well.

The service costs about $8.98 a month and you can not only send tweets via fax but they’ll also fax you back any @replies to your Twitter account.
