What exactly are iterator, iterable, and iteration?
... get "too Pythonic" by putting definitions like "X is an object that has __foo__() method" before. Such definitions are correct--they are based on duck-typing philosophy, but the focus on methods tends to get between when trying to understand the concept in its simplicity.
So I add my version.

How to check if PHP array is associative or sequential?
...t WTF is that it even does this to floats; if you try var_dump([1.2 => 'foo', 1.5 => 'bar']); you'll discover that you get the array [1 => 'bar']. There's no way whatsoever to find out a key's original type. Yes, all this is awful; PHP's arrays are by far the worst part of the language, and...

By definition, IDisposable is merely a mechanism to allow you to release unm...
When should I really use noexcept?

You asked for a specific example. Consider this code:
void foo(int x) {
try {
bar();
x = 5;
// Other stuff which doesn't modify x, but might throw
} catch(...) {
// Don't modify x
}
baz(x); // Or other statement using x
}
The flow gr...
What is the difference between javac and the Eclipse compiler?

What Content-Type value should I send for my XML sitemap?
...8.
For text/xml, text/xml-external-parsed-entity, or a subtype like text/foo+xml, the encoding attribute of the XML declaration within the document is ignored, and the character encoding is:
the encoding given in the charset parameter of the Content-Type HTTP header, or
us-ascii.
