Clustering vs Similarity

Off late, I’ve been looking at search and classification tools, so it’s only appropriate that I make a post on the topic.

These terms can be confusing to differentiate. Similarity is a more general term eg. all documents in a set that talk about linux. The act of clustering similar documents further classifies them eg. documents containing information about linux applications, linux kernel development, linux security etc .

Still confused? Try out http://clusty.com , a cluster classifying search engine and enter a search term . The results are all related (similar) but are classified into discrete clusters.

Installing Ubuntu Studio

Here’s the magic command (that I can never remember) to add ubuntu studio and , perhaps more importantly for me, a real time kernel, onto my existing ubuntu install (I could probably get along with the standard ubuntu desktop + the rt kernel, but eye candy is always cool) . Tip found at  http://www.ubustu.com/globe/2007/05/23/add-ubuntu-studio-to-an-existing-ubuntu-install/

sudo apt-get update && sudo apt-get install ubuntustudio-desktop ubuntustudio-audio ubuntustudio-audio-plugins ubuntustudio-graphics ubuntustudio-video linux-rt

Eclipse RCP tutorial on Ganymede

As powerful as Eclipse RCP is, it’s not very easy to find good tutorials on it.  There’s the ubiquitous link to an IBM tutorial on the topic, but here’s a (IMHO) superior alternative: http://www.vogella.de/articles/RichClientPlatform/article.html
