Android accelerometer accuracy (Inertial navigation)
... Spatial databases are optimized for this using divide and conquer to only allocate sectors that are meaningful. It would be sort of like those MIT projects where the laser-equipped robot starts off with a black image, and paints the maze in memory by taking every turn, illuminating where all the wa...
Is recursion a feature in and of itself?
...airly expensive compared to iteration (in general) because it requires the allocation of a new stack frame. Not to mention you can get a stack overflow exception if the input is not valid too many times.
I believe the professor deducted points since recursion is considered a subject of its own and ...
What does Ruby have that Python doesn't, and vice versa?
... actually a bit of a misnomer. Modules are basically classes sans the new, allocate methods. They work best as a way to share code on a per class/object basis, not as mechanism for partitioning libraries, or to share code across programs.

Is R's apply family more than syntactic sugar?
...u mean to set y to 1:1e6, not numeric(1e6) (a vector of zeroes). Trying to allocate foo(0) to z[0] over and over does not illustrate well a typical for loop usage. The message is otherwise spot on.

How do arrays in C# partially implement IList?

What is an IndexOutOfRangeException / ArgumentOutOfRangeException and how do I fix it?
...ith a limitation: they can't grow, if you need more elements you need to reallocate that array (this may take a relatively long time if old items must be copied to a new block). You resize them with Array.Resize<T>(), this example adds a new entry to an existing array:
Array.Resize(ref array,...
Using smart pointers for class members
...w pointers are bad when used for performing manual memory management, i.e. allocating and deallocating objects through new and delete. When used purely as a means to achieve reference semantics and pass around non-owning, observing pointers, there is nothing intrinsically dangerous in raw pointers, ...
