scrollIntoViewIfNeeded 4 everyone!!!

This gist provides a simple JavaScript implementation of the non-standard WebKit method scrollIntoViewIfNeeded that can be called on DOM elements.

Usage

Just use the code in index.js in your app or website. You can see usage in the test page test.html.

The parent element will only scroll if the element being called is out of the view. The boolean can force the element to be centered in the scrolling area.

public class WaitNotifyExample {

  public static void main(String[] args) {
		Integer lock = new Integer(0);
		Thread waiter = new Thread(new Waiter(lock));
		waiter.start();
		Thread notifier = new Thread(new Notifier(lock));
		notifier.start();
	}

function CubicSolve(a, b, c, d){

  b /= a;
  c /= a;
  d /= a;

  var discrim, q, r, dum1, s, t, term1, r13;

  q = (3.0*c - (b*b))/9.0;
  r = -(27.0*d) + b*(9.0*c - 2.0*(b*b));

Clustering: The basics

The trick? pass the file descriptor from a parent process and have the server.listen reuse that descriptor. So multiprocess in their own memory space (but with ENV shared usually)

It does not balance, it leaves it to the kernel.

In the last nodejs > 0.8 there is a cluster module (functional although marked experimental)

• http://nodejs.org/api/cluster.html
• Simple cluster example:

function rus_to_latin ( str ) {
    
    var ru = {
        'а': 'a', 'б': 'b', 'в': 'v', 'г': 'g', 'д': 'd', 
        'е': 'e', 'ё': 'e', 'ж': 'j', 'з': 'z', 'и': 'i', 
        'к': 'k', 'л': 'l', 'м': 'm', 'н': 'n', 'о': 'o', 
        'п': 'p', 'р': 'r', 'с': 's', 'т': 't', 'у': 'u', 
        'ф': 'f', 'х': 'h', 'ц': 'c', 'ч': 'ch', 'ш': 'sh', 
        'щ': 'shch', 'ы': 'y', 'э': 'e', 'ю': 'u', 'я': 'ya'
    }, n_str = [];

// remove parent without removing childen
function unwrap(wrapper) {
	// place childNodes in document fragment
	var docFrag = document.createDocumentFragment();
	while (wrapper.firstChild) {
		var child = wrapper.removeChild(wrapper.firstChild);
		docFrag.appendChild(child);
	}

	// replace wrapper with document fragment

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
