I don't understand. You gave them your old card and now you're making
a new card for yourself?
You'll need to swipe it again. It looks like somebody rebooted the
door computer and the error log was erased.
CC'ing access list
last night Lesley and I went to see what was wrong with the front door
computer, because it was not responding on the network. Unfortunately sudobot
did not alert us to the fact, but Lesley noticed.
anyway, perhaps related to the table setup in front of the cafe bench, the
loosely-hanging extension cord duct-taped to the outlet on the east wall, which
powers the network switch near the front door computer, may have come loose. I
plugged it back in but then looked at the beaglebone black and it was totally
dark, powered off, which i've seen before.
why would a beaglebone black turn itself off?
i unplugged the TWO usb cables going into the cylindrical USB power socket
(which takes 12V from the backup battery) and then plugged them back in. This
is necessary since the second USB cord powers the hub and the magnetic stripe
reader won't recognize properly if it's not power-cycled with the beaglebone.
after this everything worked, but i still have no idea why the beaglebone was
off.
also i wish sudobot would tell us when it fails to connect to omnidoor!

Hi Steven,
I put you into the system with that card, please let me know if it works for
you.
when you swipe into the building, our chat channels' bot will introduce you as
"Steven Low" if you would like to use a handle or nickname, or just be

ok i did it. although i see that your previous card worked 8 times in a row
this morning at 10:45am
did the door not open for you then?

I just want to bump this thread and see if anyone is available to work on the
physical aspects of the door opener I describe below, and as shown in this
diagram:
http://spaz.org/~jake/pix/omnidoormotor1.png
I am willing to do the electronics part of it and make it work with our
existing system, but I would like others to help with the building of a bracket
to hold the motor in place over the door, and the woodwork and nuts&bolts of
making the 2x2 stick with steel cable attached to it.

Hello,
This is to confirm that your item has been shipped at Tue, 31 Jan 2017
06:01:23 +0300.
Please check delivery label attached!
With thanks and appreciation.
Elie Loury - USPS Station Manager.
the problem is that the way our card reader is currently configured makes it
impossible to differentiate between good reads of readable cards, and the
myriad ways the card reader says "I WAS UNABLE TO READ THAT CARD PROPERLY"
because the software takes the KEYBOARD SCAN CODES sent by the reader (because
it pretends to be a keyboard) and HASHED THE SCAN CODES SEQUENCE through a
trapdoor algorithm... so we have no way to know what was scanned.
this means that many people had the door code equivalent of "CARD READ ERROR"
which meant that anyone could swipe any card in the reader, in a way where it
would say "CARD READ ERROR" or whatever, and get the door open.
we hacked a kludge into the software a while ago that would count the number of
keyboard scan codes that came from the card reader, before they go through the
trapdoor algorithm, and just throw out anything shorter than 100 characters,
which presumably includes the error codes.
i have no idea how your card could have been mangled in a way that it's still
reading (which means its checksum is intact) but that it's different from
before. I think it means that the present reading of your car is an error code
(that's longer than 100 bytes i guess)
don't worry, it's not your problem. we'll eventually figure out a way to fix
it i guess. we're certainly going to add an RFID system, hopefully with a
more sustainable design, and maybe someday phase out the magstripe cards
entirely? I don't know.
note: door access email list is CC'd to this message.

it would have been nice if sudobot had alerted us to the fact that it was not
hearing back from the front door computer, but i think that functionality has
been disabled? I can't tell why it doesn't work.
https://github.com/sudoroom/sudobot
fixing the bot, so it alerts us when there is a problem, should be our next
step toward higher reliability of the front door system.
does anyone volunteer to do that? it's running on the sudoroom server (in the
building) under its own username, using psy as a process manager.
