Every computer system would crash at midnight on Dec 31, 1999 because programmers in the 1970s had stored years as 2-digit numbers. 99 rolled to 00, and—disaster. At NTU, we treated it seriously. Every system we touched had the same problem: years stored as YY instead of YYYY. The fix was mechanical but tedious: find every date field, add validation, test like hell.https://www.rik-kisnah.ai/posts/early-linux-at-ntu/Mon, 17 Sep 2001 00:00:00 +0000https://www.rik-kisnah.ai/posts/early-linux-at-ntu/The Linux Revolution Reaches NTU By September 2001, Linux was transitioning from hobbyist project to legitimate alternative to proprietary Unix systems. NTU, as a forward-thinking institution, started deploying Linux in labs. After years of expensive proprietary systems, here was an free, open operating system that actually worked. For students raised on Windows, encountering Linux was revelatory. The source code was available. You could modify it. You could understand how everything worked down to the kernel level.
