State of Data Last Week – Nov 20

November 21, 2010

No SoD newsletter next week. Happy Thanksgiving, Everyone!

#Analysis –Signups increased by 60% — after removing the signup form! Yet another KSU (Keystrokes per Sign-up) victory!

#Architecture – RIP Web SQL Database – W3C Working Group killed it this week L

#Big Data – Secrets of LinkedIn Data Scientists

#DBMS – What happens when you try to UPDATE a record with EXACTLY same values as before? Is it wasted work? Bad news – actual record does get (redundantly) modified; Good News – the index doesn’t.

#learning – Least scary way of learning Ruby (with Zombies). It needs register with email. Nice material (even technical ones!).

#visualization – Mozilla Data Visualization contest is now open with data sets.

How to Tell Stories with Data is a aggregation of tools and methods. Most slides are online now.

#etc

  • Tarrot card readers – or life insurers – could tell how long you would live by just looking at cookies at your browser?
  • Housing crash was (also) blamed on ‘dramatic fall in inter-state migration rate’. This analysis (PDF) from FED now shows the fall is not that dramatic; resulted from wrong way of compensating for missing data. Data quality, anyone?
  • How to show off big numbers – ‘annual mileage of U-Haul trucks, trailers and tow dollies would move a family to the moon and back more than 20 times per day, every day of the year’. Tow dollies! Seriously??
  • Mind boggling soccer free kicks – why so difficult for even expert Goal keepers when taken from far? The ball takes sharpest spin when it slows down the most. Pretty much the same for baseball.
