Off to Be the Wizard by Scott Mayer. Hear me out. This is a comedy novel in the vein of Pratchett or Douglas Adams. But the central conceit is that a hacker finds a large configuration file on a system he hacks into. He finds his name in the file, and information about himself, including his x,y,z co-ordinates. He discovers that if he changes those co-ordinates, he teleports in reality. He has infact found the configuration file that runs our reality. He rapidly gets himself into legal trouble and so - to escape - teleports himself to England in the Middle Ages to pose as a Wizard. Its a very silly novel but programming takes center stage and - if you accept the central conceit of the configuration file - the programming is all realistic. Recommended. Scott Mayer is also a cartoonist who does the long running 'Basic Instructions' webcomic.
