State of Data -#46

#analysis – Wow! Amazon.com’s latest letter to shareholders (PDF) – from Jeff Bezos – mentions “data” 13 times and starts as if it is a Data Company –

#big_data – How Orbitz uses Hadoop to complement their Enterprise Data Warehouse Strategy – Presentation made in Chicago Data Summit on 04/26

#DBMS – Core vs. Thread – Craig Shallahamer was intrigued by ‘a couple examples where database servers have exhibited more power then the number of CPU cores could provide, which implies threads are indeed providing some extra power…so some investigation seems warranted

#learning – Visual Gotcha – Why bridges look totally non-realistic on Google Earth – “The images are the result of mapping a 2-dimensional image onto a 3-dimensional surface. Basically, the satellite images are flat representations in which you only see the topmost object—in this case you see the bridge, and not the landmass or water below the bridge. However, the 3D models in Google Earth contain only the information for the terrain–the landmass or the bottom of the ocean.
