Did the media blow the situation up? Yes
Was it a real issue? Also yes.

The reason not much happened was because hordes of developers worked tirelessly to fix systems, I know, I was one of them.

Trust me - stuff was going to break, I saw code for Banks, Hospitals and Mass transport and it was all going to fail

I bet also some of the people fixing the programs for Y2K were unaware of some of those rules...

Y2K was indeed real.

As an aside, the best, tongue in cheek, marketing ploy of those days was the Y2K compliant vegetable brush.

How to reconcile that with thousands (millions) of systems that were under peril to fail, and yet not one big enough to notice.
I mean, how come no major issue fell through the cracks? Were engineers 100% succesfull?

It definitely was real, but conspiracy theories exists in all walks of life, so I guess it's just par for the course that (some) people doubt Y2K.

We just rolled out a huge project across multiple states with no issues at all. I don't think people realize how amazing this was because we just made it look too easy. It was three years of hard work with a one year sprint at the end.

And that doesn't address the y2k failures that happened basically every 5 years after 2000 as software where the problem was "solved" by redefining the rollover date using a window rolled over.

Yes! I was working over midnight at a major hospital and then.... nothing bad happened. (The joy of being a senior in the system)

Nothing happening was due to all the planning and work that lots of professionals put in in advance of Y2K

A video store software called "Videka" jumped from 1999 straight to 2001. Quick testing showed it did consider it a leap year, which gave hope.

Some messing around and I saw a string like

19941995199619971998199920012002200320042005

in the binary... so yeah, I binary patched it to the correct sequence and it worked perfectly.

I suspect it was made in QuickBasic and for some odd reason had logic like

Year$ = MID("19941995...2005", Year% * 4 + 1, 4)

for whatever dumb reason...

Soon after video stores became irrelevant.]]>https://board.circlewithadot.net/post/https://misskey.de/notes/al2g8atl2jhttps://board.circlewithadot.net/post/https://misskey.de/notes/al2g8atl2jTue, 14 Apr 2026 17:17:43 GMT<![CDATA[Reply to Having watched another video saying Y2K wasn’t real - my standard clarification on Tue, 14 Apr 2026 17:13:56 GMT]]>@jonn_blanchard I literally had this conversation not an hour ago. It wasn't an issue because we fixed it before doomsday.

I remember back in 1999, I knew a guy who ran a public access show about Y2K prepping. He was so full of shit, but he was good looking and charismatic, so people listened to him.

I knew so many people who prepped HARD, bought trucks and trailers(for mobility), guns guns guns, stockpiled food and water. It was nuts and pathetic.

And then some of us woke up that morning and enjoyed our coffee.

Of course it was real... lived through it. Had to work overtime to make sure things went smoothly. I was in telecoms at the time.

These videos are the same as the flat-earth ones. Not worth anyone's time or bandwidth.
