AS3 IRC Desktop Client

A goal of this is to create a base resource of knowledge around IRC and specifically the capturing the knowledge for both building and using IRC Clients.

Basics of IRC Client communication.

IRC is protocol that operates over a TCP/IP socket connection with ASCII encoding typically on port 6667.

In order to connect an IRC Server a socket must first be opened on the appropriate port. This is done in AS3 by using the flash.net.Socket class, and passing the hostname as a string (DNS host name or IP) and a port number as an integer.
<pre>
var socket:flash.net.Socket = new flash.net.Socket("irc.freenode.net", 6667);
</pre>
The Socket class generates an Event.CONNECT when the connection is established, several other error events can be generated if the connection fails.
Once the socket is open the Client needs to register the connection by sending a NICK and USER command, all messages are sent to the server with the Socket method writeUTFBytes, all messages must be terminated with the ASCII character pair of CRLF (\r\n), and the flush method is called to send the queued data.
<pre>
socket.writeUTFBytes("NICK the-x\r\n");
socket.writeUTFBytes("USER thex experimental irc.freenode.net :John Doe\r\n");
</pre>
Upon successful registration the server will respond with a numeric messages 001..004.

Sample connection to irc.freenode.net, captured socket data to/from babel client.

Gate

2012-12-23T22:49:22Z

ᐃ: /* Maintenance & Repair */

This page documents the operation of Noisebridge's front gate, located at 2169 Mission Street.

= Documentation =

The gate is opened using the intercom pad inside Noisebridge, next to the door to the stairs. The "DOOR" button, illustrated with a picture of a key, opens the gate.

This switch can also be operated remotely, through an arcane and un-neccessarily convoluted system. A cable leads from the keypad through the machine shop, and up to a parallel port pair mounted on a PCB, just next to a hole in the South wall. The cable from the other side of this hole leads along the ceiling to a parallel port attached to the very top of the Wall O Tubes. This is a USB parallel port connected to [[Minotaur]].

This USB parallel port is controlled by a daemon called <tt>[https://github.com/noisebridge/gateman gateman]</tt>, which -- like all services on Minotaur -- is started automatically by [http://upstart.ubuntu.com Upstart]. <tt>gateman</tt> is called by the Noisebridge API. Minotaur also hosts the [[keycode access]] system which uses API to open the gate. Other systems including the <tt>opengate</tt> script on [[Pony]] also open the gate this way.

= Usage =

* To open the gate from outside the space, see [[getting in]].
* To open the gate from inside the space, use the "DOOR" button on the intercom pad.
* If you are too lazy to get out of your seat and, use the <tt>opengate</tt> script on Pony.
* If you are setting up another system to open the gate, write your application to use the Noisebridge [[API]]. The API only works from within the space, so you should probably run your service on Pony. Do not try to run your system on Minotaur unless you've brought it up at a [[meeting]].

= Maintenance & Repair =

The electric latch release mechanism on the gate, shown broken and jammed. To remove and repair this, unscrew the two phillip head screws and slide out the mechanism. There are also two black wires each connected to a twisted pair of cable with a wire nut that need to be disconnected to fully remove the unit.

The actual electro-mechanical part of the lock is attached with two rivets to attaching face plate, one of this is highlighted with the red arrow, and is that part that tends to break loose. This can/has been repaired by using a metal punch/drift/vise and sledge hammer.
