A link sharing service that consists of a Firefox extension and a web service.

The firefox extension creates an area to show the share UI served from the web service.

The web service handles the OAuth work and sending of messages to different share servers.

Some directory explanations:

  • extensions: holds the Firefox extension source.
  • web: holds the UI for the web service.
  • grinder: a load testing tool.
  • tools: deployment tools.
  • The rest of the files support the web service.

sudo rm /usr/bin/gcc
sudo ln -s /usr/bin/gcc-4.0 /usr/bin/gcc
