From Freenode IRC `#math` channel this morning:

    <oops> I have a confusion.  the calculation that was giving
           me 2 bits earlier is not giving me 2 bits now.  :(  please help.
    <oops> 4 equally probable symbols: so 4 * (1/4) * log(1 / 1/4), right?
    <antonfire> yeah math changes sometimes.
    <antonfire> probably a math storm
    <antonfire> wait a few minutes and try again
    <_Ray_> try logging out and back in
    <oops> so, so 1 * log(4) = 2
    <oops> oh it is giving me 2 bits again
    <mariano|syzygy> hmmm, actually he was not his advisor
    <oops> thanks, nvm.
    <sig^> try switching math off and on again
    <thermoplyae> haha
    <_Ray_> yeah, it was the router
