AWS EMR Case Study with Hive
To look into a great case study of using Hive on top of AWS' EMR, see here.

Deepwater Horizon, Siemens PLC and Stuxnet
Stuxnet may have missed its target and may have caused other damage. Read F-Secure's Q&A regarding use of Siemens PLC in Deepwater Horizon.
Simple "Hello World" Using Grand Central Dispatch ( BSD , OS-X )
Simple piece of GCD code:
#include "stdio.h"
#include <dispatch/dispatch.h>
#include <Block.h>
int main()
{
dispatch_queue_t dq;
dq = dispatch_queue_create("HelloWorld", NULL);
dispatch_block_t block = ^{printf("===========Hello world.\n");};
dispatch_async(dq,block);
dispatch_main();
return 0;
}

Shtting Down Stuxnet in Infected Systems
A possible approach to remove Stuxnet is to create an anti-body superior in its "resilience" in comparison to the Stuxnet malware itself.
The anti-body should be just as "infective" if not more, i.e. it must be possible to have it installed in all relevant systems on the network, in a manner similar to Stuxnet itself.
Spreading like a manner similar to Stuxnet itself, and possiblly in a more viral manner, the anti-bodies will disable Stuxnet for garbage collection.
This seems like the best approach to me when it comes to super-infections. At least that's how it happens in our bodies.
Iran has made some interesting advances in drug invention and production.
I will not be surprised to see Iran become a leader or a leading partner in the production of cyber anti-bodies that work against malware from cyber criminals.
By the way, my conjecture is that those who created the Stuxnet -- whose operations are essentially akin to biological warfare -- have most probably also created some anti-bodies.
Of course, there's an art in creating anti-bodies and in immunology.
That same art needs to be applied here.
