# MacGifer

![Vote KO widget](http://f.cl.ly/items/1n3g0W0F0G3V0i0d0321/Screen%20Shot%202012-11-04%20at%2010.01.36%20AM.png)

In a divided world, streaming formats are a matter of inclusion. GIF was introduced by CompuServe in 1987, they didn't know how powerful it was going to be. 26 years later, using NodeJS together with Redis, WebRTC, websockets, webworkers and HTML5, MacGifer introduces GIF-based streaming, making it possible for Internet Explorer 6.0 to be part of society once again.

## Requirements
```sh
# Redis
sudo add-apt-repository ppa:chris-lea/redis-server
sudo apt-get update
sudo apt-get install redis-server
```

## Deploying

```sh
# ssh access
ssh deploy@sophilabs.2013.nodeknockout.com
ssh root@sophilabs.2013.nodeknockout.com

# or, if you get prompted for a password
ssh -i ./id_deploy deploy@sophilabs.2013.nodeknockout.com
ssh -i ./id_deploy root@sophilabs.2013.nodeknockout.com

# using the included script
./deploy nko
```

## How does it work?
