Y2k global shutdown problems and solutions of the millennium bug

Background[ edit ] Y2K is a numeronym and was the common abbreviation for the year software problem. The abbreviation combines the letter Y for "year", and k for the SI unit prefix kilo meaning ; hence, 2K signifies It was also named the "Millennium Bug" because it was associated with the popular rather than literal roll-over of the millenniumeven though most of the problems could have occurred at the end of any ordinary century.

There were other contenders. Y2K just came off my fingertips. Since programs could simply prefix "19" to the year of a date, most programs internally used, or stored on disc or tape, data files where the date format was six digits, in the form MMDDYY, MM as two digits for the month, DD as two digits for the day, and YY as two digits for the year.

As space on disc and tape was also expensive, this also saved money by reducing the size of stored data files and data bases.

Some such programs could not distinguish between the year and the year Other programs tried to represent the year as This could cause a complete failure and cause date comparisons to produce incorrect results. Some embedded systemsmaking 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 was done were particularly dire: While some commentators and experts argued that the coverage of the problem largely amounted to scaremongering[10] it was only the safe passing of the main "event horizon" itself, 1 Januarythat fully quelled public fears.

Some experts who argued that scaremongering was occurring, such as Ross AndersonProfessor of Security Engineering at the University of Cambridge Computer Laboratoryhave since claimed that despite sending out hundreds of press releases about research results suggesting that the problem was not likely to be as big a problem as some had suggested, they were largely ignored by the media.

I used to write those programs back in the s and s, and was proud of the fact that I was able to squeeze a few elements of space out of my program by not having to put a 19 before the year. Back then, it was very important. We used to spend a lot of time running through various mathematical exercises before we started to write our programs so that they could be very clearly delimited with respect to space and the use of capacity.

It never entered our minds that those programs would have lasted for more than a few years.

As a consequence, they are very poorly documented. If I were to go back and look at some of the programs I wrote 30 years ago, I would have one terribly difficult time working my way through step-by-step.

Many tricks were used to squeeze needed data into fixed-field character records. Saving two digits for every date field was significant in this effort. In the s, computer memory and mass storage were scarce and expensive. Early core memory cost one dollar per bit.Y2K bug, also called Year bug or Millennium Bug, a problem in the coding of computerized systems that was projected to create havoc in computers and computer networks around the world at the beginning of the year (in metric measurements K stands for thousand).

Y2k global shutdown problems and solutions of the millennium bug

Various scenarios now flit threateningly across the horizon. If we're brave enough to peer . The much-hyped millennium bug failed to wreak any kind of chaos as Britain got back to work today, although bug watchers cautioned that Y2K computer problems could yet emerge. Robin Guenier, head.

They were hand-picked to kill the Millennium Bug. They hunkered down and started cranking out code. The Y2K Solution: Run for Your Life!! For one, the Y2K bug is not simply a matter of. The Year problem, also known as the Y2K problem, the Millennium bug, the Y2K bug, or Y2K, is a class of computer bugs related to the formatting and storage of calendar data for dates beginning in the year Problems were anticipated, and arose, because many programs represented four-digit years with only the final two digits — .

Sometimes called the Year problem or the "millennium bug", the Y2K problem results from the longstanding practice of writing computer programs to store and handle only the last two digits of the year, assuming the first two would always be "19".

Most experts now acknowledge that it is too late to fix all the problems in time, and that.

Y2K: The "Millennium Bug" System Failures Y2K Problem The Year Problem (Y2K) exists in computer systems where a two-digit year field is used and the years and after cannot be distinguished from years before (i.e. from ), resulting in potential erroneous date-based calculations. The Year problem, also known as the Y2K problem, the Millennium bug, the Y2K bug, or Y2K, is a class of computer bugs related to the formatting and storage of calendar data for dates beginning in the year Problems were anticipated, and arose, because many programs represented four-digit years with only the final two digits — .
