How to display Base64 images in HTML?
...age = 'http://images.itracki.com/2011/06/favicon.png';
// Read image path, convert to base64 encoding
$imageData = base64_encode(file_get_contents($image));
// Format the image SRC: data:{mime};base64,{data};
$src = 'data: '.mime_content_type($image).';base64,'.$imageData;
// Echo out a sample im...
Modulo operation with negative numbers

Should the compiler be smart enough and detect that an unsigned modulo another unsigned is always positive? Currently (well, GCC 5.2) the compiler seems to think that "%" returns an "int" in this case, rather than "unsigned" even when both operands are uint32_...
What is the strict aliasing rule?
... ability to give aliasing warnings, sometimes giving us a friendly warning and sometimes not.)
To see why this behavior is undefined, we have to think about what the strict aliasing rule buys the compiler. Basically, with this rule, it doesn't have to think about inserting instructions to refresh th...
C++: Rounding up to the nearest multiple of a number
OK - I'm almost embarrassed posting this here (and I will delete if anyone votes to close) as it seems like a basic question.

design a stack such that getMinimum( ) should be O(1)
...) is still just a peek operation. For example, taking the original version and pushing 1 again, we'd get:
Real stack Min stack

Captured variable in a loop in C#
...ariable declaration. In fact it'll create appropriate new closure objects, and it gets complicated (in terms of implementation) if you refer to variables in multiple scopes, but it works :)
Note that a more common occurrence of this problem is using for or foreach:
for (int i=0; i < 10; i++) //...
In c# is there a method to find the max of 3 numbers?
...e, but not regularly.
(Note that this is likely to be more efficient than Andrew's LINQ-based answer - but obviously the more elements you have the more appealing the LINQ approach is.)
EDIT: A "best of both worlds" approach might be to have a custom set of methods either way:
public static class...
Array.sort() doesn't sort numbers correctly [duplicate]
...y otherwise. Anyone know why?
You're getting a lexicographical sort (e.g. convert objects to strings, and sort them in dictionary order), which is the default sort behavior in Javascript:
