Ask HN: What novels feature realistic computing?

We've all come across the hacker who is programming a worm in a time race with the three letter agency trying to trace their phone call. Or the descriptions of state of the art UIs that sound like a reject from a high-school UX module. Or computing as far-future brain-jacked retina-implanted VR mumbo-jumbo.

But are there good programmers or technical folks in novels too? Are there storylines that give you the sense that the author knows what he's talking about?

Any recommendations?
