...exec() blah blah ...) .In terms of implementation complexity, it will range from the simple and effective ( eg scripting ) to the complex and wonderful ( some programmed connector interface) . All depends on how crazy you want to go with it , and how much sweat capital you are willing to s...
A simple explanation of Naive Bayes Classification
... say that we have data on 1000 pieces of fruit. They happen to be Banana, Orange or some Other Fruit.
We know 3 characteristics about each fruit:
Whether it is Long
Whether it is Sweet and
If its color is Yellow.
This is our 'training set.' We will use this to predict the type of any new fruit ...
Why does struct alignment depend on whether a field type is primitive or user-defined?
.... That means we can no longer use an 8-byte integer to represent the whole range of time we're interested in. That has prompted me to investigate the memory usage of the (many) structs of Noda Time, which has in turn led me to uncover a slight oddity in the CLR's alignment decision.

...t 2 times, or as many as 4. So that 60% measurement is more like a general range from 40% to 80%. If it were only 40%, would you say the problem is not worth fixing? So what's the point of time accuracy, when what you really want is to find the problems?
500 or 5000 samples would have measured the p...
What is the difference between bottom-up and top-down?
...uting all the Fibonacci numbers as you go.
fib[0] = 0
fib[1] = 1
for i in range(48):
fib[i+2] = fib[i] + fib[i+1]
In any interesting scenario the bottom-up solution is usually more difficult to understand. However, once you do understand it, usually you'd get a much clearer big picture of how t...

Fastest way to iterate over all the chars in a String
...ice as fast as String.charAt(i) (178% faster). The average speed over this range was 1.111 billion characters per second.
The Field must be obtained ahead of time and then it can be re-used in the library on different strings. Interestingly, unlike the code above, with Field access, it is 9% faster ...
