BigData - Volume, Variety, Velocity (and Variability?)

-
IBM seemed to have the definitive word in the definition of BigData, i.e.,

  • Volume - Quantity.  D-uh.
  • Variety - Different types of data, such as audio, video, text, etc.
  • Velocity - The rate at which this data changes


To the above, Forrester (hidden behind a paywall, of course), wants to add a fourth term

  • Variability - The different meanings/contexts associated with a given piece of data
It does makes sense.  I have always referenced Variety to subsume Variability, but it probably makes sense to call it out as its own distinct entity.

Great to see IBM, and many other vendors and consultants, finally get on board with the 3Vs concept I created at Gartner over ten years ago. Tho it's sad to see other research orgs claim the idea as theirs. Anyone interested in the original 2001 article on the 3Vs ("Three Dimensional Data Challenge"), feel free to reach me. -Doug Laney, VP Research, Gartner

Erlang, Binaries, and Garbage Collection (Sigh)

The nice thing about garbage-collection is that it is makes memory management absolutely transparent to you Of course, the above is true right up to the point when it stops being transparent, at which point it does a phase change from nice to clusterf**k of biblical proportions .  There are entire posts, books, and suicide notes that have been written about this, and I have no great desire to add to them, save with the minor comment that paranoia about garbage-collection is still justified , albeit only in the edge-cases for most people. That said, I'll give you that Erlang GC is in many ways much, much better positioned in this regard than, oh, Java, but it still rears up and bites you in the butt when you least expect it. ( More information about Erlang's GC vis-a-vis Java here , and Jesper's truly excellent description of Erlang's GC here ).  A story from the past should serve to illustrate this. Once upon a time, in a magical land far far away - well, Her

Cannonball Tree!

Spotted this one just outside the Ravindra Kalakshetra in Bangalore .  Its called the Cannonball Tree , but is - technically (i.e., in Latin, if thats your metier) - Couroupita Guianensis , or ನಾಗಲಿಂಗ ಪುಷ್ಪಾ  in Kannada. The fruits look like Cannonballs (well, d-uh), and the flowers are really quite amazing, and pretty ludicrously distinctive...

Visualizing Prime Numbers

-
Image
From Jason Davies , we have El Patron de Los Primos , probably one of the coolest prime number visualizer that I've seen.  For every Natural number, he draws a periodic curve that intersects at that number and each of its multiples.  Needless to say, prime numbers are touched by only two curves (itself and 1 ). You can scroll to the right, and move up the prime food change. (The image above is a screen grab.  Go here to see the actual thing)
