I worked at Bell Labs in the 90s, on wireless stuff, but we were still using the "in house" cfront compiler at the time, and would e-mail the compiler group, which included Bjarne Stroustrup, with issues sometimes. I learned C++ from his book before I joined Bell Labs, so that was a bit of a holy shit moment for sure for me then.
Kernighan, Ritchie and Thompson all still worked at Bell Labs as well at the time, but the company was huge then, and they were all in a different location from my team, so I never had any opportunities to meet them.
I am still getting monthly updates on my Fenix 7X, with bugfixes and sometimes new features - 23.48 was released on 12/5
My Fenix 5 got last updated in 2022, but still works fine despite being almost 9 years old, still on the original battery too.
