#analysis – Interested in sports, and in data too? See “Gut vs. Data – How Coaches Make Decision” (often some major ones in final few seconds!)– a great panel discussion from MIT Sloan Sports Analytics Conference 2011.
#architecture – Great paper from Microsoft tells how Machine Learning helped Kinect (PDF) perfecting ‘body tracking’. Microsoft is apparently using Kinect to also manage data centers.
#big_data – MASSIVE SQL Injection Attack in progress around the web, earlier this week, mysql.com was “SQL injected” too
#DBMS – A good 1-hr /180 easy slides presentation on “NoSQL: What, Why and When”
#learning – “A Little MongoDB” (PDF) book is now made available online by the author – Chapter 1 (Basics), 4 (Data Modeling) and 5 (When to Use) apply equally well to most other ‘NoSQL’ technologies
#visualization – Looks even better than Wordle.net – build beautiful word cloud on wordlin.gs on patterns never seen before.

- Digital Data Growth – World’s largest digital picture is 40 GigaPixels, 280GB and a sheer beauty.
