Yet more wardriving equipment. I borrowed a GPS
unit from Gregory to hook to the laptop
. Yet after an hour of
fooling around I could not get anything
from the GPS
unit. Not one byte of data.
Searching around for a possible answer, I read where you might need a
NULL modem cable to talk successfully to a GPS unit. Great! While I have a NULL
modem adaptor, it's buried with the rest of the computer equipment that I've
yet to unpack. Even if I had that, the adaptor itself is a DB-25 form
factor, while the cable (and serial port on the laptop) are both
DE-9† form factors so that would require yet more
But it's a specially constructed cable for the unit so you would think
the wiring would be correct. So, using that logic (and not wanting to dig
through boxes looking for adaptors) I tried hooking the GPS up to my older laptop.
It worked. I can see data spewing forth from the GPS unit.
But the serial port on the new laptop doesn't appear to work.
† Although commonly referred to as “DB-9,” DE-9 is the
correct designation—the letters refer to the physical size of the
connector while the number referrs to the number of pins. A VGA monitor
cable uses a DE-15 connector, for instance.

The dates are the permanent links to that day's entries (or
entry, if there is only one entry). The titles are the permanent
links to that entry only. The format for the links are
simple: Start with the base link for this site: http://boston.conman.org/, then add the date you are
interested in, say 2000/08/01,
so that would make the final URL:
You can also specify the entire month by leaving off the day
portion. You can even select an arbitrary portion of time.
You may also note subtle shading of the links and that's
intentional: the “closer” the link is (relative to the
page) the “brighter” it appears. It's an experiment in
using color shading to denote the distance a link is from here. If
you don't notice it, don't worry; it's not all that
