This Year's Y2K20 Bug Came Directly From 'A Lazy Fix' to the Y2K Bug
Slashdot reader The8re still remembers the Y2K bug. Now he shares a New Scientist article explaining how it led directly to this year's Y2020 bug -- which affected more than just parking meters:WWE 2K20, a professional wrestling video game, also stopped working at midnight on 1 January 2020. Within 24 hours, the game's developers, 2K, issued a downloadable fix. Another piece of software, Splunk, which ironically looks for errors in computer systems, was found to be vulnerable to the Y2020 bug in November. The company rolled out a fix to users the same week -- which include 92 of the Fortune 100, the top 100 companies in the US.... The Y2020 bug, which has taken many payment and computer systems offline, is a long-lingering side effect of attempts to fix the Y2K, or millennium bug. Both stem from the way computers store dates. Many older systems express years using two numbers -- 98, for instance, for 1998 -- in an effort to save memory. The Y2K bug was a fear that computers would treat 00 as 1900, rather than 2000. Programmers wanting to avoid the Y2K bug had two broad options: entirely rewrite their code, or adopt a quick fix called "windowing", which would treat all dates from 00 to 20, as from the 2000s, rather than the 1900s. An estimated 80 percent of computers fixed in 1999 used the quicker, cheaper option. "Windowing, even during Y2K, was the worst of all possible solutions because it kicked the problem down the road," says Dylan Mulvin at the London School of Economics.... Another date storage problem also faces us in the year 2038. The issue again stems from Unix's epoch time: the data is stored as a 32-bit integer, which will run out of capacity at 3.14 am on 19 January 2038.Read more of this story at Slashdot.
