How can I get the behavior of GNU's readlink -f on a Mac?

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()

def main():
print "Hello World"
if __name__ == "__main__":
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...
How can I get the full object in Node.js's console.log(), rather than '[Object]'?
...) is automatically applied to every argument:
o = { one: 1, two: 'deux', foo: function(){} }; console.log(o, [1,2,3]) // -> '{ one: 1, two: 'deux', foo: [Function] } [ 1, 2, 3 ]'
Note that you cannot pass options through util.inspect() in this case, which implies 2 notable limitations:

Which is the preferred way to concatenate a string in Python?
...StringIO
# python3: from io import StringIO
buf = StringIO()

buf.write('foo')
buf.write('foo')
buf.getvalue()
# 'foofoofoo'
If you already have a complete list returned to you from some other operation, then just use the ''.join(aList)
