Just did my exam on stuff like Huffman coding/entropy/efficiency and the like along with metadata, logic, Boolean/nearness searching and algorithms and associated stuff. Not my finest hour as I've been whittling away at other things meantime, but it's done now. Hopefully get some results quite soon.
It's a bit of a shame not to have spent more time on the subjects involved. I'm genuinely interested, but the 1-year MSc is such a whirlwind that there's really no time to do anything but keep my head above water. I reckon I have already forgotten a goodish chunk of what I knew this afternoon!
