Is floating-point math consistent in C#? Can it be?
...Use native code for the math operations. Incurs the overhead of a delegate call on every math operation.
I've just started a software implementation of 32 bit floating point math. It can do about 70million additions/multiplications per second on my 2.66GHz i3.

How do HttpOnly cookies work with AJAX requests?
...est to the server.
In the case of Stack Overflow, the cookies are automatically provided as part of the XmlHttpRequest request. I don't know the implementation details of the Stack Overflow authentication provider, but that cookie data is probably automatically used to verify your identity at a lo...
Get nested JSON object with GSON using retrofit
...ss, new MyDeserializer<DiffContent>())
.create();
When you call .fromJson() the type is carried into the deserializer, so it should then work for all your types.
And finally when creating a Retrofit instance:
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(url)...
python design patterns [closed]
...
Something you can use to simplify your code when calling attributes on objects that might or might not exist is to use the Null Object Design Pattern (to which I was introduced in Python Cookbook).
Roughly, the goal with Null objects is to provide an 'intelligent'

@property retain, assign, copy, nonatomic in Objective-C
...directly own, such as delegates.
Keep in mind retain and assign are basically interchangeable when garbage collection is enabled.
@property (assign) NSInteger year;
strong is a replacement for retain.
It comes with ARC.
@property (nonatomic, strong) AVPlayer *player;

What is the difference between ArrayList.clear() and ArrayList.removeAll()?
...) is much faster since it doesn't have to deal with all those extra method calls.
And as Atrey points out, c.contains(..) increases the time complexity of removeAll to O(n2) as opposed to clear's O(n).

How do I close a single buffer (out of many) in Vim?
...e is not talking about the w command. He put this warning there so people did not think the bw command meant buffer write (which it does not it means buffer wipeout.)

What makes Lisp macros so special?
...ros for code but that is best illustrated below:
So we can define a macro called lcomp (short for list comprehension). It's syntax will be exactly like the python that we used in the example [x for x in range(10) if x % 2 == 0] - (lcomp x for x in (range 10) if (= (% x 2) 0))
(defmacro lcomp (...
What is the correct way to document a **kwargs parameter?
...
The example is likely subprocess.call(*popenargs, **kwargs). It is documented as subprocess.call(args, *, stdin=None, stdout=None, stderr=None, shell=False) where everything after the * is the recognized keys in **kwargs (Or at least the ones frequently used...
Get size of an Iterable in Java
...t values is actually a Collection and not only an Iterable, check this and call size() in case:
if (values instanceof Collection<?>) {
return ((Collection<?>)values).size();
}
// use Iterator here...
The call to size() will usually be much faster than counting the number of elements...
