Why is it said that “HTTP is a stateless protocol”?
...gh multiple requests can be sent over the same HTTP connection, the server does not attach any special meaning to their arriving over the same socket. That is solely a performance thing, intended to minimize the time/bandwidth that'd otherwise be spent reestablishing a connection for each request.

Need to remove href values when printing in Chrome
...
Bootstrap does the same thing (... as the selected answer below).
@media print {
a[href]:after {
content: " (" attr(href) ")";
}
}
Just remove it from there, or override it in your own print stylesheet:
@media print {

Spring @Transaction method call by the method within the same class, does not work?
...
The problem here is, that Spring's AOP proxies don't extend but rather wrap your service instance to intercept calls. This has the effect, that any call to "this" from within your service instance is directly invoked on that instance and cannot be intercepted by the wrapp...

Is there a generic constructor with parameter constraint in C#?
...
As you've found, you can't do this.
As a workaround I normally supply a delegate that can create objects of type T:
public class A {
public static void Method<T> (T a, Func<float[,], T> creator) {
//...do something...
}

Selecting element by data attribute
... give faulty results.
Note that for compatibility with the Selectors API (document.querySelector{,all}), the quotes around the attribute value (22) may not be omitted in this case.
Also, if you work with data attributes a lot in your jQuery scripts, you might want to consider using the HTML5 custo...
Bash script absolute path with OS X

There's a realpath() C function that'll do the job, but I'm not seeing anything available on the command-line. Here's a quick and dirty replacement:
#!/bin/bash
realpath() {
[[ $1 = /* ]] && echo "$1" || echo "$PWD/${1#./}"
}
realpath "$0"

Redirect from an HTML page

Additionally for older browsers if you add a quick link in case it doesn't refresh correctly:
<p><a href="http://example.com/">Redirect</a></p>
Will appear as
Redirect
This will still allow you to get to where you're going with an additional click.
