'const int' vs. 'int const' as function parameters in C++ and C
...
const T and T const are identical. With pointer types it becomes more complicated:
const char* is a pointer to a constant char
char const* is a pointer to a constant char
char* const is a constant pointer to a (mutable) char
In other words, (1) and (2) are identical. The only way of ma...
Why does C# disallow readonly local variables?
... -1 In C++ there's no machine code support for const (which in C++ is more like C# readonly than like C# const, although it can play both roles). Yet C++ supports const for local automatic variable. Hence the lack of CLR support for a C# readonly for local variable, is irrelevant.

It would be nice to see this re-used in a more standalone fashion. Are you volunteering? I can help with some of the R bits.

Algorithm to generate a crossword
...crossword, give it a score based on how many of the words were placed (the more the better), how large the board is (the smaller the better), and the ratio between height and width (the closer to 1 the better). Generate a number of crosswords and then compare their scores and choose the best one.

...t = doubles.Aggregate(1.0, (prod, next) => prod * next);
See MSDN for more information. It lets you specify a seed and then an expression to calculate successive values.

Why do most fields (class members) in Android tutorial start with `m`?
... ignore the prefix (or suffix) to see the meaningful part of the name. The more we read the code, the less we see the prefixes. Eventually the prefixes become unseen clutter and a marker of older code." - Robert Martin in Clean Code

How do you clear a stringstream variable?
..."");
is correct, although using:
m.str(std::string());
is technically more efficient, because you avoid invoking the std::string constructor that takes const char*. But any compiler these days should be able to generate the same code in both cases - so I would just go with whatever is more read...
Finding the index of elements based on a condition using python list comprehension
...t; 2)
[2, 5]
Note that I'm using lists here to mimic Matlab. It would be more Pythonic to use generators and iterators.
