Linked list with pointers? is this 19th century or what?

I'd say they'd need to do linked lists with pointers (and somesuch) exactly because it's not the 19th century. Languages - and teaching of them - drives new coders away from basic knowledge, also de-emphasizing knowledge of basic algorithms. The result is a bit frustrating - for me at least it is - since I feel (I work in a research institute with connections to universities) the handicaps they sometimes have because of this, and they don't even know the cause.

And FYI, just recently I had to create a tree structure with pointer node interlinks from the ground up, since no preexisting ones I could use would produce the preformance I wanted, it took me a few hours and it works great. It's not what I do every day, but if the knowledge is there, than it's no problem. If the knowledge is not there, well let me put it this way, sometimes you can't tolerate a few hours of work to go on for days and produce inferior results just because the coder doesn't have the necessary basic algorithmic and coding knowledge.
