Why do I need to explicitly push a new branch?
...as a remote tracking branch, and/or having the same name)
So you need at least to do a:
git push origin master
But if you do only that, you:
will create an upstream master branch on the upstream (now non-empty repo): good.
won't record that the local branch 'master' needs to be pushed to upst...
What's the meaning of interface{}?
...ethods.
Since there is no implements keyword, all types implement at least zero methods, and satisfying an interface is done automatically, all types satisfy the empty interface.
That means that if you write a function that takes an interface{} value as a parameter, you can supply that funct...
How do I declare a 2d array in C++ using new?
...you put the index calculation in a function which adds extra overhead. At least, consider using macros or inline functions to reduce overhead. An example macro for C++: #define ROW_COL_TO_INDEX(row, col, num_cols) (row*num_cols + col) Then you can use it as int COLS = 4; A[ ROW_COL_TO_INDEX(r, c, C...
What is a Java ClassLoader?
...oaded and running.
A class loader creates a namespace. All JVM include at least one class loader that is embedded within the JVM called the primordial (or bootstrap) class loader. That is one thing, and we will look at non-primordial class loaders. The JVM has hooks in it to allow user defined clas...

I had the same problem, and this dirty hack got it fixed, at least until I can fix it in a cleaner way.
public ActionResult Login(string returnUrl)
{
if (AuthenticationManager.User.Identity.IsAuthenticated)
{
AuthenticationManager.SignOut();

Post-increment and pre-increment within a 'for' loop produce same output [duplicate]
... set i = i + 1
goto test
done: nop
Post-increment would have at least another step, but it would be trivial to optimize away
set i = 0
test: if i >= 5 goto done
call printf,"%d",i
set j = i // store value of i for later increment
set i = j + 1 // oops, we're...
What is a plain English explanation of “Big O” notation?
...his looking. No matter how long your actual algorithm takes, it will be at least O(N) because it spent that time looking at all the data.
The same can be said for the very act of writing. All algorithms which print out N things will take N time because the output is at least that long (e.g. printin...
Best practice for localization and globalization of strings and labels [closed]
...parate module (something near 10 modules). In each module we might have at least 50 CRUD forms, which means that we currently have near 500 add buttons , save buttons , edit buttons , etc.

What is the fastest way to get the value of π?
...g answers precisely how to do this in the fastest possible way -- with the least computing effort. Even if you don't like the answer, you have to admit that it is indeed the fastest way to get the value of PI.
The FASTEST way to get the value of Pi is:
1) chose your favourite programming language

...now. I think I'm going to attempt to merge the two web.config files -- at least the authentication part -- and if that doesn't work, I'll look into the various IIS7 options. Thanks again for your time and the information, Benni!
