Y2K
Y2K referring to the Year 2000 was also know as the Millenium Bug which in the most simple terms was the concern that an unknown number of business systems were coded using only two numbers to describe the year eg. 99 for 1999 and so risked when the year 2000 struck it would cause systems to think it was 1900 and so break lots of calculations/logic.
Pipe Ten was founded in 2002, but we’ve already got our sights set on Y2Kv2, Y2038 or the Epochalypse; where unix time will overflow the signed 32-bit integer commonly used today.
