Why is Git better than Subversion?
...ty much the same. There isn't much difference between:
svn checkout svn://foo.com/bar bar
cd bar
# edit
svn commit -m "foo"
and
git clone git@github.com:foo/bar.git
cd bar
# edit
git commit -a -m "foo"
git push
Where Git really shines is branching and working with other people.

Should switch statements always contain a default clause?
...ome languages you can assign integer values to enums. In C++ enum MyEnum { FOO = 0, BAR = 1 }; MyEnum value = (MyEnum)2; makes a valid MyEnum instance that is not equal to FOO or BAR. If either of these issues would cause an error in your project, a default case will help you find the error very qui...
What is the JavaScript >>> operator and how do you use it?
...ey can be used on array-like objects e.g. Array.prototype.indexOf.call({0:'foo', 1:'bar', length: 2}, 'bar') == 1;. The arguments object is also a good example. For pure array objects, it's impossible to change the type of the length property, because they implement an special [[Put]] internal metho...
FixedThreadPool vs CachedThreadPool: the lesser of two evils
...rogram that spawns threads (~5-150) which perform a bunch of tasks. Originally, I used a FixedThreadPool because this similar question suggested they were better suited for longer lived tasks and with my very limited knowledge of multithreading, I considered the average life of the threads (seve...
What does the caret operator (^) in Python do?
...ns exponentiation. You could do that this way, just as one example:
class Foo(float):
def __xor__(self, other):
return self ** other
Then something like this will work, and now, for instances of Foo only, the ^ symbol will mean exponentiation.

In plain English, what does “git reset” do?
... shouldn't be too surprising.
For example, git reset other-branch path/to/foo resets everything in path/to/foo to its state in other-branch, git reset -- . resets the current directory to its state in HEAD, and a simple git reset resets everything to its state in HEAD.
The main work tree and index...

What is a StackOverflowError?
...
If you have a function like:
int foo()
{
// more stuff
foo();
}
Then foo() will keep calling itself, getting deeper and deeper, and when the space used to keep track of what functions you're in is filled up, you get the stack overflow error.
