can we get a different graphic for this group. This graphic breaks 2 major rules or graphing:
1) don't use dimensions that don't add information (3rd dim here)
2) don't use pie charts

Hi Emory Creel,
do you have a nicer graphic you would prefer to see here?
Feel free to send it to me. Thanks.
Best regards,
Ralf

The new icon is a picture of Donald Knuth (the "father", founder of Latex, Computer science, Algorithms, etc., living in Palo Alto).

Join our Data Mining Hackathon on Big Data.  We are having a kickoff meeting this Saturday in Sunnyvale, CA (but you can join the competition any time).  The problem is product recommendation of products on the Best Buy mobile web site.  We are working with www.Kaggle.com

http://www.sfbayacm.org/DM-Hackathon-2012-10

Our competitions include:

* Hadoop sized prediction

* PC sized prediction

* Data visualization

We have support of 3 cloud computing vendors for cloud computing time to get you started.

The awards will be given at the Data Mining Camp, Sat Oct 13 in San Jose, CA. 

I also work with sponsors for www.SFbayACM.org events.

Thanks, Greg
