As a form of high praise, the only thing that I could call an error was a reference to a cable TV connector. Please forgive me but I can't get it out of my head. I'm not just a grammar Nazi, but a component extremist. :-)
Another nit is that around the middle of the story, there are some references suggesting the protagonist had a special operations background, probably SEAL. This seemed to come out of nowhere.
That being said, I admire the hero, but also recognize he's not me. If I won the lottery, I would find a place in a city with hot and cold running reference libraries and labs. But the story isn't about me, although it inspires me to try a short one about winning the lottery.
There's no sex to speak of, but that doesn't hurt the character development. Still, there are enough semi-loose ends that I give the plot and technical quality 9's rather than 10's. Maybe it wasn't possible to clarify them if the author was committed to keep the story short.
In other places, the level of detail to be very pleasant. The author gives me a very good mental picture of the house. He also has me reflecting on whether I should be refreshing my Perl, or just going to Python.
Until people see the way I cursed at the Viking eight-burner two-oven stove I put into my dream kitchen, it's hard to imagine the intensity with which I pumped the air with a YESS! when the hero put in a Wolf rather than a Viking. Great kitchens are just as sensual as sex, as well as the hot tub that could have been described in more detail.
