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.

Early core memory cost one dollar per bit. It was a liaison operation designed to mitigate the possibility of false positive readings in each nation's nuclear attack early warning systems.

Y2k end of the world

When the prophesied date came and computer clocks around the world updated to January 1, , very little actually happened. 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 problem was not likely to be as big a problem as some had suggested, they were largely ignored by the media. Date bugs similar to Y2K[ edit ] Main article: Time formatting and storage bugs 4 January [ edit ] This date overflowed the bit field that had been used in the Decsystem 10 operating systems. The abbreviation combines the letter Y for "year", and k for the SI unit prefix kilo meaning ; hence, 2K signifies Instead of a date reading , it read Some caused erroneous results, some caused machines to stop working, some caused date errors, and two caused malfunctions. There were rumors that planes would drop from the sky when clocks turned to midnight on 31st Dec

As space on disc and tape was also expensive, this also saved money by reducing the size of stored data files and data bases. With so much preparation and updated programming done before the change of date, the catastrophe was quelled and only a few, relatively minor millennium bug problems occurred — and even fewer were reported.

Updated February 16, While many were ready to party "like it was ," many others predicted catastrophe at the end of the year from a small assumption made long ago when computers were first being programmed.

Nothing happened. They are saying 'just as the year bug was all a storm in a teacup, so Brexit is all just a storm in a teacup'. Computer experts were later accused of exaggerating the concept of the "Millennium Bug" as millions of dollars were spent in preparation of the Y2K problem. The US Government followed a three-part approach to the problem: 1 outreach and advocacy, 2 monitoring and assessment, and 3 contingency planning and regulation. Norway and Finland[ edit ] Norway and Finland changed their national identification number , to indicate the century in which a person was born. Each federal agency had its own Y2K task force which worked with its private sector counterparts. Early core memory cost one dollar per bit. She argues that if Brexit is to be compared to anything, then it has far more in common with the political headache that was the handover of Hong Kong to China in For all persons born before , the month is stored as the calendar month plus 20, and for all persons born after , the month is stored as the calendar month plus The bug resulted in comparatively minor incidents that were largely fixed within hours. Many tricks were used to squeeze needed data into fixed-field character records. Neither managers nor programmers of that time expected their programs to remain in use for many decades. As a result, stock prices of banking institutions dropped in value as the year neared. No banks failed, no planes crashed, no wars or civil war started. Rule 3: In all interfaces and data storage, the century in any date must be specified either explicitly or by unambiguous algorithms or inferencing rules.

These were followed by accusations that the likely incidence of failure had been greatly exaggerated from the beginning. This allows retention of data structure alignmentusing an integer value for years.
