Spare time nerdery has turned fun lately: NaN boxing, five and six bit character codes, SCSU, ISPF, Mumps, qp-tries, CBOR. In case I appear totally miserable with computers: not totally. Still amused by some parts.
@graydon i haven't used MUMPS/M since the 90s. Flashbacks.
@graydon i was using it in a mainframe hospital setting, so, not very much.
it was an early example of a good domain-specific ORM though.
