4,282,781 | 4,282,782 | Gigantic arrays | <p>I'm planning to store gigantic arrays into serialized files and read from them in order to display data within them. The idea is to have a simple, document-oriented, filesystem database. Can anyone tell me if this would be a performance issue? Is it going to be slow or very fast?</p>

689,223 | 689,224 | Storing a set of arrays of different types | <p>As a matter of interest, lets say I have the following class:</p>
<pre><code>class Data

}:
</code></pre>
<p>So the class stores a set of vectors of any type. Each vector has a name and I know its type when retrieving it. What container might I use to store this data within the Data class? A <code>std::vector<std::pair<std::string,std::vector<T>>></code>?</p>
<p><strong>UPDATE</strong>:</p>
<p>I will also need to iterate over this class and the items must be in the same orders as I added them.</p>
<p>For example, I might have:</p>
<pre><code>ownerNames: std::vector<std::string>;
ipAddress: std::vector<char>;

4,392,006 | 4,392,007 | Persistent delayed jobs queue for Java | <p>I'm looking for an existing system to replace an existing slow and complicated self written mechanism of job management.
The existing system:</p>
<ul>
<li>1 MySQL DB with a long massive table of jobs - the queue</li>
<li>Multiple servers (written in java) all extracting jobs from the queue and processing them</li>
<li>a job might NOT be deleted from the queue after processing it, to rerun it later</li>
<li>a job might create other jobs and insert them to the queue</li>

Even after deleting bin ,web.config and everything application was still there it was working. It wasnt browser cache thing as i deleted everything and response time from server was current time.</p>
<p><strong>Problem 2</strong>
I noticed that through a proxy server returned error then. Like cache was per ip ?! Response wasnt cached as time was current.No session variable and identical requests returned different responses (only different ip)</p>
<p><strong>Problem 3</strong>
Changing something and publishing again the app via ftp , either application didnt work at all or it had the previous version. I noticed that visiting the site from another ip , or after some time fixes the problem. </p>
<p>What should i do ??? It is IIS6.0 and routing worked only when i added .aspx at each controller... But with .mvc didnt work or server didnt updated the project....</p>

4,145,288 | 4,145,289 | How to enforce an integer limit in an argument hint in Java | <p>I'm new to Java after working for a few years in PHP and I'm trying to get an idea of some of the best practices and norms when working with Java.</p>
<p>I'm wondering if it makes sense to make a whole class to act as a custom type just to enforce a limit on the range of an integer argument? </p>
<p>For example:</p>
<pre><code>class Person() {
private int age;
public Person(int age) {
if(age < 0) {
throw new IllegalArgumentException();
}
this.age = age;
}
public int getAge() {
return age;
}
}
</code></pre>
<p>Or:</p>
<pre><code>class Person() {
private Age age;
public Person(Age age) {
this.age = age;
}
public int getAge() {
return age.toInt();
}
}
class Age() {
private int age;
public Age(int age) {
if(age < 0) {
throw new IllegalArgumentException();
}
this.age = age;
}
public toInt() {
return age;
}
}
</code></pre>
<p>Also, in the second example I'm converting the Age object to an int in Person.getAge(), which is convenient but somehow feels wrong since Person's constructor takes an Age object. Any thoughts?</p>
<p>Thanks!</p>

Whenever you try and add another element into the current array, and it's full it should copy every element from the current array into the new one (including the new element that you want to add) and then delete the old array.

5,336,762 | 5,336,763 | Method parameters confusion | <p>Often time methods take more than 3 parameters which are all of the same type, eg.</p>
<pre><code>void mymethod (String param1, String param2, String param3)
</code></pre>
<p>then it's very easy for the client to mix up the parameters orders, for instance inverting param1 and param2:</p>
<pre><code>mymethod (param2, param1, param3);
</code></pre>
<p>...which can be the cause of much time spent debugging what should be a trivial matter.
Any tips on how to avoid this sort of mistake (apart from unit tests) ?</p>

268,283 | 268,284 | How to achieve the role played by "public static variables of Java" in JavaScript or a webpage? | <p>On my homepage I have to set a cookie using the name of the logged in user. The cookie <code>set</code> and <code>get</code> part has to be done in JS. On the subsequent sub pages I have to retrieve the <code>cookie(username)</code> using the <code>set</code> variable name. </p>
<p>How can I store the username/cookie name so that it is publicly accessible across all the pages? This username will obviously change with each new user and is not constant.</p>
<p>I have tried doing this using external JS file but in every new page the value is reset to default which I don't want.</p>
<p>The exact solution to my problem is like the work done by:</p>
