Research and Destroy

I just found a video which demonstrates a quite interesting approach how to multiply numbers using pen and paper just by counting some cross-points in lines. Check it out!

Funny Turing machine, which seems to work. Thanks, Manuel!

I thought of your meat-loving friends from Fettgaumen when i found this nice hero story on failblog:

“Postgres is fürn’ Ar***”

A Singleton both PHP- and JEE-DevGuys should like ;-)

The idea is that a ParallelArray represents a collection of structurally similar data items, and you use the methods on ParallelArray to create a description of how you want to slice and dice the data. You then use the description to actually execute the array operations, which uses the fork-join framework under the hood, in parallel…This idea coming in JDK 7 :)

In fact, here are some operations supported by ParallelArray:

• Filtering: selecting a subset of the elements
• Mapping: convert selected elements to another form
• Replacement: create a new ParallelArray derived from the original
• Aggregation: combine all values into a single value
• Application: perform an action for each selected element
