Which is faster: Stack allocation or Heap allocation
...single instruction on most architectures, in most cases, e.g. on x86:
sub esp, 0x10
(That moves the stack pointer down by 0x10 bytes and thereby "allocates" those bytes for use by a variable.)
Of course, the stack's size is very, very finite, as you will quickly find out if you overuse stack all...
How to compute the similarity between two text documents?
... between them. Any textbook on information retrieval (IR) covers this. See esp. Introduction to Information Retrieval, which is free and available online.
Computing Pairwise Similarities
TF-IDF (and similar text transformations) are implemented in the Python packages Gensim and scikit-learn. In th...
Why do people say that Ruby is slow? [closed]
...
First of all, slower with respect to what? C? Python? Let's get some numbers at the Computer Language Benchmarks Game:
Ruby 1.9 vs. Python3 within the same order of magnitude
Ruby 1.9 vs. PHP within the same order of magnitude

What is external linkage and internal linkage?
...n for non-const symbols and static (internal) for const symbols.
// in namespace or global scope
int i; // extern by default

Why are private fields private to the type, not the instance?
...technical point of view, there's no reason to choose one way or the other (esp. when considering that Eiffel.NET can do this with IL, even with multiple inheritance, there's no inherent reason not to provide this feature).
Of course, it's a matter of taste and as others already mentioned, quite som...
Why is this inline-block element pushed downward?
...re to grasp the idea of line boxes and how they are lined in the same line esp read last paragraph carefully because there lies the answer of your question.
The baseline of an 'inline-block' is the baseline of its last line box in the normal flow, unless it has either no in-flow line boxes or if...
ASP.NET MVC View Engine Comparison
...f great value to the ASP.NET MVC community if people add their experience (esp. anyone who contributed to one of these). Anything implementing IViewEngine (e.g. VirtualPathProviderViewEngine) is fair game here. Just alphabetize new View Engines (leaving WebFormViewEngine and Razor at the top), and...
Difference between Covariance & Contra-variance

Consider the following two subsets of the set of all C# types. First:
{ Animal,
Tiger,
Fruit,
Banana }.
And second, this clearly related set:
{ IEnumerable<Animal>,
