So the Computer Science departent at my university has a shelf where people can give away technical books they don't need anymore. I found a giant UNIX system administration book from 1995 there the other day, and i am blown away by how many useful things i could find in such an old book; basically all of the unix flavours mentioned are long dead (with the exception of bsd and linux ofc), and so is 99% of the software, but all of the core concepts and basic tasks still hold true in 2018... Isn't that amazing? :D Where else can you find a system that still works the same after 23 years?

    Ask people maintaining critical legacy stuff and you'll find: in amazingly many places: banks, planes, public transport...

    @irene that's interesting. Where do such code exist?

    Legacy systems are all over the place. It's simply not cost effective to upgrade to the latest and greatest every 2 years or whatever. As long as the system is doing what's required of it, there's no reason to break what's already working. The upside of that is you can make a load of money if you know how to perform maintenance on those systems.

    Nice find by the way! It'll serve you well

    Pretty sure in the old days people just write architecture proof Fortran code. Cuz I still use lots of subroutines date back to f77 for my work, and have to deal with binary operations which makes it less readable.
