Does anyone recall a book or short story in which the main character had a small tapwater-cooled supercomputer connected to her kitchen sink?
One scene I'm remembering includes her turning the faucet on so she could do some number-crunching without cooking the bio-based circuitry. Another includes her logging into it while not at home, but only running it at speed for a short time because she wasn't there to turn the water on.
Her apartment may have been on a space station. The character reminds me of one from Anne McCaffrey, Elizabeth Moon, or Melissa Scott, but I've not been able to find this in any of their books so far.
