Some IBM technotes definitely go into the 'Interesting - may prove useful in the future' category.  This one on IBM Connections search ranks highly for geekiness...

Question
When you search all IBM Connections components, the results are returned based on relevance. How does Connections determine which documents are most relevant?

The search is built on top of Apache Lucene, as are most of IBM's search components. Detail of the Apache Lucene project can be found here: http://lucene.apache.org/java/docs/index.html

The linked document describing the Similarity formula might help next time you are waiting for a flight or struggling to sleep:
The score of query q for document d correlates to the cosine-distance or dot-product between document and query vectors in a Vector Space Model (VSM) of Information Retrieval. A document whose vector is closer to the query vector in that model is scored higher. The score is computed as follows:

Make sure you get a cartridge that is compatible with your printer, as Amazon searches can sometimes lead you astray, especially after the 5th hit or so. The scoop free is easy to use, easy to change the cartridge, I've never needed to scoop the box, it is relatively odor free (when it starts to smell, it's time for a new cartridge), and it is quiet. This product was worth every penny and makes taking a temperature so much easier and fast. I figured, for the price how bad could it be? Let's just say a razor is definitely better than this.
