// Get whether the message has been read

1) Stop apache server from crashing down
2) prevent PC from slowing down</p>

Just that the script should execute without slowing my machine (so I can multitask) and apache shouldnt keep crashing</p>

4,991,229 | 4,991,230 | 100K curl requests | <p>I am using curl_multi_exec to process over 100K requests. I do 100 requests at a time because curl_multi_exec can only handle 100 requests at a time to eventually get to 100K requests. We have added multiple servers to this system to spread the load [we are using load balancing]. What is the best way to have curl handle 100K requests and make use of these additional servers? What is the downside (other than time) of handling that many requests on one server? How can I use the additional servers to help handle those requests?</p>
<p>I was thinking about having each server handle a batch of requests (like one server handles 500 requests, another 500, another 500, etc.. </p>
<p>To elaborate- basically, we are using curl to send out over 100K requests to third party servers. The problem with only using 1 server is that there is a memory limit in the number of requests 1 server can handle. So we decided to add additional servers, but we are not sure how to design this system to use curl to handle that many requests..</p>
<p>The third party server is an API like Facebook; they are aware that we will be making that many requests to their servers.</p>
<p>For load balancing, we use Rackspace cloud server, basically the load balancer directs incoming requests to separate servers. </p>

579,185 | 579,186 | jquery .click being called multiple times | <p>I am getting unexpected results with jQuery trying to set the "click" method of a div. Please see <a href="http://jsfiddle.net/fkMf9/" rel="nofollow">this jsfiddle</a>. Be sure to open the console window. Click the word a few times and watch the console output. The click function gets called multiple times when it should only be called once.</p>
<p>The commented out code at the end works just fine. Am I doing something wrong? I'm new to jQuery.</p>
<p>Here's the code:</p>
<pre><code>function toggleDiv(status)
{
console.log("toggleDiv(" + status + ")");
if (status) {
$("#test").html("Goodbye");
}
else {

}
$("#test").click(function() {
toggleDiv(!status);
});
// Non-jquery method works fine....
//document.getElementById("test").onclick = function () {
// toggleDiv(!status);
//}
}
</code></pre>
<p>Update: looks like there are lots of ways to skin this cat. The real issue here was my not understanding that the jQuery "click" functions ADDS another handler. I thought it REPLACED the current handler.</p>

It's supposed to represent a sentence that can contain additional sentences and/or words. My problem arises when I try to implement the TextBody class, which has functions addComponent and Print. They are supposed to add a new DocumentComponent object to the vector using push_back, and to call the print function of each element in the vector, respectively. I'm storing my objects in a vector of DocumentComponent objects/pointers called container, and I can only get one of the two to work at a time (by changing my vector to either be a vector of pointers or a vector of objects). If I do the former my print function works but not my addComponent function, and if the latter the situation is reversed. Here's my code:</p>
<p>documentComponent.h:</p>

{
public:

virtual void addComponent(DocumentComponent& comp){}
virtual void print()=0;
};

<pre><code>class TextBody : public DocumentComponent
{

<p>I'm working in C# and not using WPF as neither my input or output needs to be displayed graphically.</p>
<p>In my program I have 2 quadrilaterals, lets call them an input and an output quadrilateral.</p>
<p>The input quad has the co-ords of (2,1),(2,3),(4,4),(3,1) from bottom left clockwise.</p>
<p>The output quad can have any co-ords and will be again listed in order from bottom left clockwise.</p>
<p>Given these 8 co-ordinate pairs, is it possible to calculate a transformation matrix that I could apply to any single co-ordinate pair?</p>

2,150,881 | 2,150,882 | Building iPhone App for Distribution | <p>I have a question on how exactly to do the final distribution build for my app. I have actually successfully built this app already but now I am trying to make an updated version and to remember what I did right the first time. It all seemed to go wrong when my provisioning profile expired....</p>
<p>Anyway, I have my distribution certificate and distribution provisioning profile. I have followed the instructions from Apple, an iPhone programming book and several online sources to create a build that checks against the right certificate etc. But the build always fails unless I connect a device, which is strange as the distribution provisioning profiles do not allow the inclusion of a device (which makes perfect sense in itself). However when I build with a device connected I am asked </p>
<blockquote>
<p>'Can’t run XXX on the iPod “iPod
touch”</p>
<p>The iPod “iPod touch” doesn’t have the
provisioning profile with which the
application was signed.</p>
<p>Click “Install and Run” to install the
provisioning profile XXX on “iPod
touch” and continue running XXX.'</p>
</blockquote>
<p>When I click install and run it fails with the message that </p>
<blockquote>
<p>A valid provisioning profile for this
executable was not found.</p>
</blockquote>
<p>So my basic question is how exactly should the final distribution build be done? An new executable appears, but it has a forbidden symbol on top of the application icon suggesting the build was unsuccessful. </p>
<p>Any help massively appreciated.</p>

1,087,076 | 1,087,077 | How do you fill a Java HashMap with multiple instances of related subclasses? | <p>I have a superclass called "Canvas," from which I create several subclasses. I want to store instances of those subclasses in a dictionary. So I tried setting up my code as follows:</p>
<pre><code>public class Main {
public static void main(String[] args) throws Exception{
Canvas canvas = new Canvas();
Menu menu = new Menu();
Instructions instructions = new Instructions();
Map<String, Canvas> screens = new HashMap<String, Canvas>();
screens.put("menu", menu);
screens.put("instructions", instructions);
</code></pre>
<p>So, being that the things I want to add to the dictionary are all subclasses of my Canvas class, I set up the hashtable to accept that Type. And this works.. for the most part. However, the big problem is that I cannot access any of the subclass' methods. I can only call methods that exist in the superclass.</p>
<p>If I attempt to do something like, </p>
<pre><code>screens.get("menu").some_func_in_subclass();
</code></pre>
<p>The compiler spits out a "Can not find symbol" message. </p>

after all, a new activity is created with new listeners registered to the new views and the old ones are destroyed.</p>
<p>I know that I can fix this by telling the manifest that I'll be handling configuration changes by myself, but I'm looking into deeper understanding.</p>
