4,567,757 | 4,567,758 | Updating numerous web clients periodically from the server | <p>G'Day,</p>
<p>I am planning an ASP.NET 4 application. Not sure if it will be MVC3 or WebForms yet. I need to be able to perform the following:</p>
<ul>
<li>I have data coming into the the .NET assembly on the web server via a serial link</li>
<li>I want to send this same data to all "connected" web clients</li>
<li>I want to PUSH the changes from the server. NOT poll the server</li>
</ul>
<p>"Connected" you say? HTTP is a RESTful and there are no permanent connections. So I am guessing I need to open up a web socket or similar to do this? Ideally I would also like to know what page the connected client is on so that I don't send them data they wont need (assuming I have a correlation between what is being displayed and the data it concerns).</p>
<p>Performance and scalability are obviously issues here. I don't foresee having more than 10 simultaneous clients in the intranet I am running on. However I would like to scale it larger and potentially include Internet connected clients.</p>
<p>What are my options here? All suggestions and pointers greatly appreciated.</p>

<p>I've called a javascript function on window.load to check if the url has changed or not.</p>

function page_open(){
var pages=unescape(location.href);
pages=pages.substr( pages.lastIndexOf("studysquare.in/") + 15 );

//alert("pages"+pages+"\n\n recent"+recent);
if (pages==recent) { return; }

3,570,215 | 3,570,216 | How do I prevent/suppress SIGFPE in C++? | <p>I'm trying to convert a double to float as well as various integer types inside a dll, which is used as a Game Maker extension. I don't need a sensible result if the double doesn't fit the range of the target types, so I simply used a static_cast.</p>
<p>Everything works as intended when I call this code from my own test C++ application, but when it's called from Game Maker, range errors raise SIGFPE for some reason, which leads Game Maker to terminate my program with an error message.</p>
<p>I don't need sensible results for out-of-range conversions, but crashing is a no-no. I tried using llround instead of a cast, but it also raises the signal.</p>
<p>I also tried catching the signal myself by using signal(SIGFPE, SIG_IGN); right before the conversion, but it didn't change the behaviour at all. Maybe the ominous comment in the mingw signal.h has something to do with that: "SIGFPE doesn't seem to work?"</p>
<p>I checked the source code of a different dll used in a Game Maker extension, and the binary provided by the author performs simple cast conversions without a problem. When I compile the source myself however, the SIGFPE problem is present again. I am guessing that the author used a different compiler, but I'd prefer to stay with mingw if possible. </p>
<p>So, how do I either perform these conversions safely, or prevent the signal from being generated when I perform them with a simple cast? I'm using mingw-g++ 4.5.0 to compile at the moment.</p>
<p>Here's the function where the problem happens:</p>
<pre><code>template<typename ValueType>
static double writeIntValue(double handle, double value) {
boost::shared_ptr<Writable> writable = handles.find<Writable>(handle);
if(writable) {
// Execution reaches this point
ValueType converted = static_cast<ValueType>(value);
// Execution doesn't reach this point if e.g. ValueType
// is short and value is 40000
writable->write(reinterpret_cast<uint8_t *>(&converted), sizeof(converted));
}
return 0;
}

mycompnay - myclient - - myphone
</code></pre>
<p>so the first row would create a company object with an address of "myaddress".
The second row would create another company object (which by my rules is the same company as the name is the same), this also having a client reference and a phone number.</p>
<p>So I would know they are the same but need to ensure all the data is merged into one object.</p>
<p>At the moment I am creating a utility class that takes both objects, (one being the primary and the other to be merged, so one has priority if there is a clash), it goes through each variable and assigns the values if there are any. This is a bit boiler plate heavy and I was hoping there might be some utility I could utilize to do the manual work for me.</p>
<p>The example has been simplified as there are a fair few other variables, some basic types and others that are more complex items.</p>

<p>What is wrong with this implementation of insert for this structure ? How should I fix this?
<strong>added:</strong> Very sorry that I wasn't clear. I know what is wrong with the program. I want to know how I can insert a new node to a reference node. Since I am using a reference to a node as a param this mean that node must not be a pointer? So its stored on stack? which means I can't use memory from heap? (or else seg fault?) so how am I suppose to use new ? This is my main confusion. Perhaps my approach is wrong but I don't see why it should be.</p>

4,452,401 | 4,452,402 | "nice" keyword in c++? | <p>So I was doing some simple C++ exercises and I noticed an interesting feat. Boiled down to bare metal one could try out compiling the following code:</p>
<pre><code>class nice
{
public:
nice() {}
};
int main()
{
nice n;
return 0;
};
</code></pre>
<p>The result is a compilation error that goes something like this:</p>
<pre><code><file>.cpp: In function ‘int main()’:
<file>.cpp:11: error: expected `;' before ‘n’
<file>.cpp:11: warning: statement is a reference, not call, to function ‘nice’
<file>.cpp:11: warning: statement has no effect
</code></pre>
<p>And this was using regular g++ on Max OS X, some of my friends have tried in on Ubuntu as well, yielding the same result.</p>
<p>The feat seems to lie in the word "nice", because refactoring it allows us to compile. Now, I can't find the "nice" in the keyword listings for C++ or C, so I was wondering if anyone here had an idea?</p>
<p>Also, putting</p>
<pre><code>class nice n;
</code></pre>
<p>instead of</p>
<pre><code>nice n;
</code></pre>
<p>fixes the problem.</p>
<p>P.S. I'm a relative C++ newbie, and come from the ActionScript/.NET/Java/Python world.</p>
<p><strong>Update:</strong></p>
<p>Right, my bad, I also had an</p>
<pre><code>#include <iostream>
</code></pre>
<p>at the top, which seems to be the root of the problem, because without it everything works just fine.</p>

4,136,219 | 4,136,220 | Java Old JRE Installation Issue | <p>At my company, we have an internal application that uses Java. It evidently must use 7.0.5, since the app stops working on machines that have been upgraded to 7.0.7. We have an installer stored on the network here that I was not initially notified about. Here's the situation.</p>
<ul>
<li>Two identical machines: "Laptop A" and "Laptop B"</li>
<li>I downloaded a copy of jre-7u5 from oldversion.com and installed it on Laptop A.</li>
<li>Java doesn't run in firefox on Laptop A (according to javatester.org as well as oracle's java site). I have set extensions.blocklist.enabled to "false", and plugins.hide_infobar_for_outdated_plugin to "true"</li>
<li>I found out about the installer we already had before getting to Laptop B. Seeing as it was already on the NAS, I used it to install on Laptop B, and it works fine. I have uninstalled java on Laptop A, and reinstalled using our "known good" installer, to no avail. </li>
</ul>
<p>Is there any way I can resolve this? If not, the laptop can be requisitioned for another department, which doesn't use our custom app, but it would be best if I could get it going.</p>

4,074,927 | 4,074,928 | Safe json parsing with jquery? | <p>I am using jquery with json. My client pages generate json, which I store on my server. The clients can then fetch the json back out later, parse, and show it.</p>
<p>Since my clients are generating the json, it may not be safe. I think jquery uses eval() internally. Is that true? Is there a way to use the native json parsers from the browsers where available, otherwise fall back to manual parsing if not? I'm new to jquery so I don't know where I'd insert my own parsing code. I'm doing something like:</p>
<pre><code>$.ajax({
url: 'myservlet',
type: 'GET',
dataType: 'json',
timeout: 1000,
error: function(){
alert('Error loading JSON');
},
success: function(json){
alert("It worked!: " + json.name + ", " + json.grade);
}
});
</code></pre>
<p>so in the success() method, the json object is already parsed for me. Is there a way to catch it as a raw string first? Then I can decide whether to use the native parsers or manual parsing (hoping there's a jquery plugin for that..).</p>
<p>The articles I'm reading are all from different years, so I don't know if jquery has already abandoned eval() already for json,</p>
<p>Thank you</p>
