<p>What level of CPU usage should be considered high for SQL Server? ie 80% 90% 100%?</p>
| <p>if under normal loads the CPU averages above 40% I start to get nervous. However, that's because I know the nature of our traffic and the spikes we get. Your mileage may vary.</p>
| <p>It really depends on your machine. The best thing is to monitor the server using perfmon and see when things start to run slowly. It is normal for SQL to use a lot of CPU under load.</p>

<p>In a PHP project I'm developing I have a couple of requests that can be either POST or GET. Currently, I'm using the $_SERVER[REQUEST_METHOD] value to determine, which request array to use. I know that $_REQUEST values can be manipulated with cookies, is the $_SERVER superglobal vulnerable to attacks? </p>
| <p>The $_SERVER superglobal is filled by PHP with data it gets from the web server.</p>
<p>So unless the attacker replaces the web server with his own, or manages an extremely lucky buffer overflow against the server, you are fine.</p>
| <p>REQUEST_METHOD isn't limited to POST and GET though - you also need to handle HEAD (IIRC PHP will terminate the script at the first sign of output when it sees that header) and (on unlikely setups) you might get a few WebDAV ones.</p>

<p>What's the best way to animate a background image sliding to the left, and looping it? Say I've got a progress bar with a background I want to animate when it's active (like in Gnome or OS X).</p>
<p>I've been playing with the <code>$(...).animate()</code> function and trying to modify the relevant CSS property, bu... | <p>As soon as I posted this I figured it out. In case it helps anyone else, here's the function I came up with:</p>
<pre><code>function animateBar(self) {
// Setup
var bar = self.element.find('.ui-progress-bar');
bar.css('background-position', '0px 0px');
bar.animate({

<p>If I had a phone number like this </p>
<pre><code>string phone = "6365555796";

<p>Which I store with only numeric characters in my database <strong>(as a string)</strong>, is it possible to output the number like this: </p>
<pre><code>"636-555-5796"

<pre><code>string number = "1234567890";
string formattedNumber = string.Format("{0}-{1}-{2}", number.Substring(0,3), number.Substring(3,3), number.Substring(6));
</code></pre>
| <p>To control string format of a number for display in an ASP.NET Gridview or another control, you can wrap your item in a helper class for display purposes:</p>
<pre><code>public class PhoneDisplay
{
long phoneNum;
public PhoneDisplay(long number)
{
phoneNum = number;
}

<p>Sometimes my meshes turn out with artifacts Which can be seen in the bottom image. What is the cause? The first image shows my mesh which its generated from.
I've tried multiple slicers. This tends to occur sometimes.
Any help appreciated. Is there something going over my head???</p>

<p>In a tic-tac-toe implementation I guess that the challenging part is to determine the best move to be played by the machine.</p>
