Why shouldn't all functions be async by default?
...ch in the functional language community has gone into figuring out ways to identify how to optimize code that makes heavy use of continuation passing style. The compiler team would likely have to solve very similar problems in a world where "async" was the default and the non-async methods had to be...
How does having a dynamic variable affect performance?
...t represents the operation. So, for example, if you have:
class C
{
void M()
{
dynamic d1 = whatever;
dynamic d2 = d1.Foo();
then the compiler will generate code that is morally like this. (The actual code is quite a bit more complex; this is simplified for presentation pu...
Breadth First Vs Depth First
...alking a tree.
It is probably easiest just to exhibit the difference. Consider the tree:
A
/ \
B C
/ / \
D E F
A depth first traversal would visit the nodes in this order
A, B, D, C, E, F
Notice that you go all the way down one leg before moving on.
A breadth first traversa...

The first 3 answers to your questions are listed as inline comments, beside each method, in the example HTTP POST above.
From getOutputStream:
Returns an output stream that writes to this connection.

Library? Static? Dynamic? Or Framework? Project inside another project
...s://github.com/jverkoey/iOS-Framework
This is a pretty straight-forward guide and doesn't have the disadvantage of dealing with "fake static libraries"... check it out for more info...
Once you've created your static library, it's as easy as including it as a submodule within Git for use across di...
What is Ember RunLoop and how does it work?
... silly to asks and dependant on many things but I am looking for a general idea, or maybe if there is a minimum or maximum time a runloop may take)
At no point will the RunLoop ever keep track of how much time it's taking to propagate all the changes through the system and then halt the RunLoop aft...
Using Kafka as a (CQRS) Eventstore. Good idea?
...
I was looking at Kafka and had another concern: I didn't notice anything about optimistic-concurrency. Ideally I could say: "Add this event as item N+1 only if the object's most recent event is still N."
