Call Go functions from C
...nt {
return a + b
}
// This is the public function, callable from outside this package.
// It forwards the parameters to C.doAdd(), which in turn forwards
// them back to goCallbackHandler(). This one performs the addition
// and yields the result.

What's the need of array with zero elements?
...eof(*var) + extra, GFP_KERNEL);
This used to be not standard and was considered a hack (as Aniket said), but it was standardized in C99. The standard format for it now is:
struct bts_action {
u16 type;
u16 size;
u8 data[];
} __attribute__ ((packed)); /* Note: the __attribute__ is i...
Trim string in JavaScript?
... return this.replace(rtrim, '');
};
})();
}
That said, if using jQuery, $.trim(str) is also available and handles undefined/null.
See this:
String.prototype.trim=function(){return this.replace(/^\s+|\s+$/g, '');};
String.prototype.ltrim=function(){return this.replace(/^\...
What are transparent comparators?
... programs in some way so there was no consensus to add the feature. We decided that although it wouldn't be safe to add the feature unconditionally, it would be safe if it was disabled by default and only "opt in".

How to get the containing form of an input?
...
I agree. As I said, I just wasn't initially sure if the form property was extensively implemented in all common browsers. I've edited my answer to more explicitly list this as the better option while I'm leaving closest as a tidbit if this w...
std::function and std::bind: what are they, and when should they be used?
...a,b) := f(a, 4, b);
g is a "partial application" of the function f: the middle argument has already been specified, and there are two left to go.
You can use std::bind to get g:
auto g = bind(f, _1, 4, _2);
This is more concise than actually writing a functor class to do it.
There are further...
Why is TypedReference behind the scenes? It's so fast and safe… almost magical!

Greenlet Vs. Threads

Greenlets provide concurrency but not parallelism. Concurrency is when code can run independently of other code. Parallelism is the execution of concurrent code simultaneously. Parallelism is particularly useful when there's a lot of work ...
(413) Request Entity Too Large | uploadReadAheadSize
...f IIS but the problem of WCF. WCF by default limits messages to 65KB to avoid denial of service attack with large messages. Also if you don't use MTOM it sends byte[] to base64 encoded string (33% increase in size) => 48KB * 1,33 = 64KB
