Why do this() and super() have to be the first statement in a constructor?
...ic methods. What I wanted to do looked something like this:
public class Foo extends Baz {
private final Bar myBar;
public Foo(String arg1, String arg2) {
// ...
// ... Some other stuff needed to construct a 'Bar'...
// ...
final Bar b = new Bar(arg1, arg2);
super(b.baz())...
Pass a local file in to URL in Java
...and then lists the host (generally omitted), followed by "/" and the path "foo/bar" (generally meant to be read as an absolute path). Thus "file:///foo/var". An URI that looks like "file:/foo/bar" is incorrect. See also: file URI scheme

How do you print in a Go test using the “testing” package?
... issue 24929
Consider the following (silly) automated tests:
func TestFoo(t *testing.T) {
t.Parallel()
for i := 0; i < 15; i++ {
t.Logf("%d", i)
time.Sleep(3 * time.Second)
}
}
func TestBar(t *testing.T) {
t.Parallel()
for i := 0; i < 15; i++ {

What is the logic behind the “using” keyword in C++?
...n-deducible context. That is, it will not be possible to
call the function foo below without explicitly specifying template
arguments.
template <typename T> void foo (Vec<T>::type&);
So, the syntax is somewhat ugly. We would rather avoid the nested ::type

Qt: *.pro vs *.pri
...l .pro files as the need arises. This is how you would use it in practice:
foo.pri
FOO = BAR
hello.pro
...
include($$PWD/foo.pri)
...
world.pro

include($$PWD/foo.pri)

This way, the commonality would be available both in hello.pro as well as world.pro. It does not make much of difference i...

Set value of textarea in jQuery
...
val(foo) works for me (jQuery 1.9.1). Using text(foo) loses to update textarea content loses the linebreaks on IE, using val(foo) preserves them.

How to show changed file name only with git log? [duplicate]
...puts a list of files only and their state (added, modified, deleted):
A foo/bar/xyz/foo.txt
M foo/bor/bar.txt

The -k2,2 option for sort, makes it sort by file path instead of the type of change (A, M, D,).

Load “Vanilla” Javascript Libraries into Node.js
...o export.
So for a library like the file ./lib/mylibrary.js...
function Foo() { //Do something... }
biz = "Blah blah";
var bar = {'baz':'filler'};
When you want to use its functionality in your Node.js code...
var vanilla = require('vanilla');
var mylibrary = vanilla.require('./lib/mylibrary.j...
Join strings with a delimiter only if strings are not null or empty
...
Consider
var address = "foo";
var city;
var state = "bar";
var zip;
text = [address, city, state, zip].filter(Boolean).join(", ");
console.log(text)
.filter(Boolean) (which is the same as .filter(x => x)) removes all "falsy" values ...
