Time Event
BTGPS Billionton Bluetooth GPS (with LCD display)

Okay, it was *really* cheap. And it shows. It scared me when I
opened it, and it contains Li-ION battery, with "temperature" pin not
connected. It does charge from USB, but don't try charging it from USB
hub. It is actually usefull -- once it catches enough sattelites. And
that takes *long* time :-(. Its lcd display can show sattelite status,
X,Y,Z coordinates, speed and heading, and distance to waypoint. That's
pretty much it. It does *not* display heading to waypoint (oops!) and
while it contains a map, it does not put "here you are" arrow on the
map, and even fails to scroll the map as you are moving... (AFAICT, it
basically zooms map at random location). Making map unusable. Some
screens fail to refresh (going from heading 350.34 to heading 0.12
displays 0.1234 :-), and if battery gets low, it will hang up and
break in mysterious ways, instead of simply powering down.

GPSes. It has 5 key control (up, down, ok, esc, menu); control is too
logical, but you can get used to it. (Entering waypoint names is

Okay, later I found out that if I keep it powered down while it
can't reach sattelites, it actually tends to lock much faster and is
almost getting usable.

I'll put my notes there

Funny network at novotel
I was pleasantly surprised that I had public IP at Novotel in Ottawa... 198.162.X.X... then vojtech pointed out that they probably just "misspelled" 192.168.X.X, and quick traceroute confirmed it ;-).
