Video Chat on Etherpad gets an upgrade

Posted on by John McLear

Today I pushed my new version of the Tokbox plugin for Etherpad.

Tokbox gives you the ability to have video chats on pads. To enable video chat you will have to install the plugin by visiting /admin/plugins on your etherpad deployment and searching for tokbox.

So What’s new?

  1. More user control such as enable/disable video chat.
  2. Site admins to specify their Tokbox key
  3. Better support for “Page View”
  4. Many UI bugfixes
  5. A nice icon for controlling Video Chat

Enjoy!

NFC Glass capsule 12mm x 2mm 13.56Mhz

Posted on by John McLear

I managed to source some 13.56Mhz 12mm x 2mm NFC Glass capsules / tags from China and I’m happy to sell them for 10$ a piece. If you want one please contact me, I’m too lazy to list them on any online auction stores etc.

The read range is pretty much limited to contact when using them with a mobile phone reader or other low range reader device.

They are not sterilized so should not be used for human implants and they are based on the NXP semiconductors 15693 chip.

They are read/writable, not Mifare (See above).

The MoQ for is 500 and at that point the price drops to 5$ per unit.

Special offer during Feb/March 2013 — Order 20 tags for just 160$

  color-stop(28%,rgba(255,50,248,1)),
  color-stop(41%,rgba(238,50,255,1)),
  /* green */
  color-stop(42%,rgba(42,201,40,1)),
  color-stop(55%,rgba(0,160,11,1)),
  /* purple */
  color-stop(56%,rgba(122,24,122,1)),
  color-stop(69%,rgba(122,24,122,1)),
  /* orange */
  color-stop(70%,rgba(255,146,50,1)),
  color-stop(83%,rgba(255,139,50,1)),
  /* blue */
  color-stop(84%,rgba(30,87,153,1)),
  color-stop(100%,rgba(30,87,153,1))
  );
}

Apply the rainbow class to your element IE 

<div class=rainbow>...

Etherpad: Error raised: Error: listen EADDRINUSE

Posted on by John McLear

This error is caused by the port you are trying to listen on is already in use (possibly by Etherpad or another piece of software)

In this case port 9001 was already in use.

To fix this make sure all other instances of etherpad lite are stopped then restart Etherpad Lite.

If the problem still persists try to change the port in settings.json and then restart Etherpad Lite.
