ICT “Glitches” are smaller brothers of “Bugs” which in turn can become major security disasters. Well sometimes they can make us (the one benefitting innocently from the Glitch) happy or at least they can make us laugh. This case is quite notable: “Bank error makes restaurant manager the world’s first ever trillionaire (and he even offered to pay off the national debt before the glitch was spotted)”.
I am also addicted to this blog “IT Hiccups of the Week” which sometime reports on some very good discounts (due to some kind or another of Glitch) we just missed at our local supermarket.
