How to measure time in milliseconds using ANSI C?
...sTmrQueryFreq (for GCC compiler):
#define INCL_DOSPROFILE
#define INCL_DOSERRORS
#include <os2.h>
#include <stdint.h>
ULONG freq;
DosTmrQueryFreq (&freq);
query the current ticks value with DosTmrQueryTime:

Is async HttpClient from .Net 4.5 a bad choice for intensive load applications?
...t directly answer the 'async' part of the OP's question, this addresses an error in the implementation he is using.
If you want your application to scale, avoid using instance-based HttpClients. The difference is HUGE! Depending on the load, you will see very different performance numbers. The Htt...
Can someone explain the “debounce” function in Javascript
...defined timer identifier causes it to just do nothing, it doesn't throw an error or something.
The second point is done by the produced function. It first stores some information about the call (the this context and the arguments) in variables so it can later use these for the debounced call. It th...
Is JavaScript a pass-by-reference or pass-by-value language?
...ng; if it was passed by const ref trying to do changeObject would cause an error, rather than just failing. Try assigning a new value to a const reference in C++ and the compiler rejects it. In user terms, that's the difference between pass by value and pass by const reference.

Calling parent class __init__ with multiple inheritance, what's the right way?
... gives you more consistancy and make eventual refactorings easier and less error-prone. An example of how to do that:
class C(A, B):
def __init__(self):
print("entering c")
for base_class in C.__bases__: # (A, B)
base_class.__init__(self)
print("leaving c"...
What is the correct way to create a single-instance WPF application?
...is loading an application and it is already open and you're giving them an error message like 'Another instance of the app is running. Bye' then they're not gonna be a very happy user. You simply MUST (in a GUI application) switch to that application and pass in the arguments provided - or if comman...
Try-catch speeding up my code?
...ot at the mercy of tiny timings, floating point arithmetic and accumulated error.
Having made that change, see whether the "non-catch" version is still slower than the "catch" version.
EDIT: Okay, I've tried it myself - and I'm seeing the same result. Very odd. I wondered whether the try/catch was...

...ith the parent directive.
Moreover, if such a controller is not found, an error will be raised.
Why use link at all
There is no real need to use the link function if one is defining the controller since the $scope is available on the controller. Moreover, while defining both link and controller, ...

What is the explanation for these bizarre JavaScript behaviours mentioned in the 'Wat' talk for Code
...e. {} and [] both return a string, so you are done.
Otherwise, throw a TypeError.
For dates, step 1 and 2 are swapped. You can observe the conversion behavior as follows:
var obj = {
valueOf: function () {
console.log("valueOf");
return {}; // not a primitive
},
