2:14:45x1bzzr Q: Why is it that software companies increasingly seem to not care about performance? I've heard you talk about the technical reasons, but I still don't understand why companies would give up on having better software quality than their competitors. Is it because education is bad? Is it because non-performance oriented software is being normalized to the point people don't care about it? Is it because hardware has been compensating for the lack of software performance?

2:19:04mattiamanzati Q: About my question before the stream started, I am looking for a doubly linked list structure, and usually that's done through a structure with a first and last entry pointers, and those have a structure with a next, prev and value pointers. (Let's call this entry_structure.) In order to add an item to the end of the list you need to create a new entry_structure, set the prev pointer to the previous last entry, and UPDATE THE LAST entry_structure in order to have next point to the new last item. Is there any other structure that represents a doubly linked list without this prerequisite?
