What's the longest lifetime of one of your applications where you did a significant portion of the implementation?

I just got a warning message out of the blue from one of mine. It was written in 2005/2006 several employers ago and still going strong!

Started programming in 2013, so definitely nothing before that.

I interned and later worked at a company between 2017 and 2019 where I laid the foundation of the embedded system. It's still being used as the basis of their system (of course with updates). If you git blame it, then you will still see my name in significant parts.

Funny thing is that even after the 2.0 version I made, which made things a lot better, I now know so much more that I think it kinda sucks now 😋 But that's a good thing (for me) actually.

@Geoxion If you look at what you wrote 18+ months ago and don't have any fresh ideas for improvements it means you have stagnated. So the more you cringe, the more you've improved!

Warning message hardcoded to send to a personal email address instead of the team distribution list...?

I have probably some 3-5 year old stuff thats in use from past internships (I got paid so no worries).

One aspect I also find fascinating is, if your software has features that even fool you.
Had this with an system that has controllers connected through lan but optionally can use wifi. While the device as in use, I only noticed at the evening, that those were actually using wifi because the lan switch didn't have power. This was outdoors, so there was next to no latency spikes, hence I didn't notice it.

@OldNotOld It was my mobile phone number. Urgent warnings were sent out to developers that way so we could be woken up at night and look into it..

Man, I miss those days. Not.
