On the contrary, I thought it was actually an interesting history of poker players using software to track hand history (a subject which is very common to his blog), and how the industry/area grew into using Postgres. Its not really meant to be a technical article but rather a history of sorts.
As an aside, does anyone else ever feel the desire to start programming some sort of poker app whenever they read codingthewheel? Seems like it'd be such a fun area for a side-project!
I've you're serious about writing a poker bot, you should check out the forums at http://pokerai.org. I recently started developing a bot and found several useful nuggets of information on the site. Be warned though, everything feels like a hack when writing a poker bot (specifically determining the state of the game from a screenshot ... kind of a pseudo-OCR).
And finally, no, I haven't made any significant income from my bot (as it current only plays preflop on 6-max tables ... I manually takeover after the flop).
Codingthewheel actually did a pretty intensive and in-depth series of blog posts about building a poker bot, you might want to check it out if you haven't already. IIRC covered things like communicating with the other processes, using Win32 APIs to scrape the text and controls of the poker client, how poker clients attempt to detect bots, etc.
