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.

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...
Getting values from query string in an url using AngularJS $location
...e so:
$location.search().user
If you wish not to use a key, value like ?foo=bar, I suggest using a hash #test_user_bLzgB ,
and calling
$location.hash()
would return 'test_user_bLzgB' which is the data you wish to retrieve.
Additional info:
If you used the query string method and you are g...

Why is Python running my module when I import it, and how do I stop it?
...rt the module and call the main(). For example, assume this is in the file foo.py.
def main():
print "Hello World"
if __name__ == "__main__":
main()
This program can be run either by going python foo.py, or from another Python script:
import foo
...
foo.main()

import .css file into .less file
...
This will create an additional http-request for foo.css, so the (inline) directive (see stackoverflow.com/a/22594082/160968) is now preferrable

Checking Bash exit status of several commands efficiently
...ncourages bad practice. Consider the simple case of ls. If you invoke ls foo and get an error message of the form ls: foo: No such file or directory\n you understand the problem. If instead you get ls: foo: No such file or directory\nerror with ls\n you become distracted by superfluous informatio...
