Screencast : Fun with Couchbase, MapReduce and Twitter

I have created this simple screencast to show how you can, using Couchbase do some realtime analysis based on Twitter feed.

The key steps of this demonstration are

1. Inject Tweets using a simple program available on my Github Couchbase-Twitter-Injector
2. Create views to index and query the Tweets by
• User name
• Tags
• Date

The views that I used in this demonstration are available at the bottom of this post.

How to watch YouTube videos offline (on OS X)?

Lately I have been traveling a lot, and I was not able to access the internet all the time; but I still want to look at some YouTube video, for example the greate Google I/O Sessions...

My needs are simple :

• running on OS X (Lion)
• download the video easily
• no need to convert the file (to be able to read the file as soon as possible)
• free

After some basic research, I found an easy way to achieve this using the following softwares:

• Enolsoft Free YouTube Downloader HD : this software allows you to download easily the YouTube FLV on your hard drive. 
• VLC Media Player : to play the FLV file locally. 

  Enjoy!
