...hors like <a href="#anchor">, query string anchors like <a href="?foo=bar"> and path fragment anchors like <a href=";foo=bar">, with the <base> tag you're basically declaring all relative links relative to it, including those kind of anchors. None of the relative links are re...
What is the scope of variables in JavaScript?
...nction expressions are scoped only to the expression itself:
(function foo() { console.log(foo) })()
console.log(typeof foo) // undefined, because `foo` is scoped to its own expression
In non-strict mode, implicitly defined properties on the global object are globally scoped. In strict mod...
How do you generate dynamic (parameterized) unit tests in python?
...ass TestSequence(unittest.TestCase):
@parameterized.expand([
["foo", "a", "a",],
["bar", "a", "b"],
["lee", "b", "b"],
])
def test_sequence(self, name, a, b):

Best practices for exception management in Java or C# [closed]
...e the issues are
pretty easy to see there. Let's say I
create a method foo that declares it
throws exceptions A, B, and C. In
version two of foo, I want to add a
bunch of features, and now foo might
throw exception D. It is a breaking
change for me to add D to the throws
clause of th...
How do I compare strings in Java?
...ical in-line strings are actually the same object.
For example:
String fooString1 = new String("foo");
String fooString2 = new String("foo");
// Evaluates to false
fooString1 == fooString2;
// Evaluates to true
fooString1.equals(fooString2);
// Evaluates to true, because Java uses the same ob...
How can I get the behavior of GNU's readlink -f on a Mac?
...can tell, that won't work if a parent dir of the path is a symlink. Eg. if foo -> /var/cux, then foo/bar won't be resolved, because bar isn't a link, although foo is.

$location.search().user

Additional info:
If you used the query string method and you are g...
Why should I care that Java doesn't have reified generics?
...oss this "need", it ultimately boils down to this construct:
public class Foo<T> {
private T t;
public Foo() {
this.t = new T(); // Help?
}
}
This does work in C# assuming that T has a default constructor. You can even get the runtime type by typeof(T) and get the con...
