Data dominates. If you've chosen the right data structures and organized things well, the algorithms will almost always be self-evident. Data structures, not algorithms, are central to programming.

Sockets are the X windows of IO interfaces.

Not only is UNIX dead, it's starting to smell really bad.

Rule 1. You can't tell where a program is going to spend its time. Bottlenecks occur in surprising places, so don't try to second guess and put in a speed hack until you've proven that's where the bottleneck is

If POSIX threads are a good thing, perhaps I don't want to know what they're better than.

There's nothing in computing that can't be broken by another level of indirection.
