<h2>Solution</h2>
<p>I found out why. in php.ini I had <code>memory_limit = 256M</code>. Maybe this is considered as an upper limit</p>

965,079 | 965,080 | Succesive calls to cProfile/pstats no updating properly | <p>I'm trying to make successive calls of some profiler code however on the second call to the function the update time of the profile file changes but the actual profiler stats stay the same. This isn't the code I'm running but it's as simplified an example I can come up with that shows the same behaviour.</p>
<p>On running, the first time ctrl+c is pressed it shows stats, second time same thing but rather than being fully updated as expected only the time is, and third time program actually quits. If trying, ideally wait at a few seconds between ctrl+c presses.</p>
<p>Adding profiler.enable() after the 8th lines does give full updates between calls however it adds a lot of extra profiler data for things I don't want to be profiling.</p>
<p>Any suggestions for a happy medium where I get full updates but without the extra fluff?</p>
<pre><code>import signal, sys, time, cProfile, pstats
call = 0
def sigint_handler(signal, frame):
global call
if call < 2:
profiler.dump_stats("profile.prof")
stats = pstats.Stats("profile.prof")

1,051,069 | 1,051,070 | "using" namespace equivalent in ASP.NET markup | <p>When I'm working with DataBound controls in ASP.NET 2.0 such as a Repeater, I know the fastest way to retrieve a property of a bound object (instead of using Reflection with the Eval() function) is to cast the DataItem object to the type it is and then use that object natively, like the following:</p>
<pre><code><%#((MyType)Container.DataItem).PropertyOfMyType%>
</code></pre>
<p>The problem is, if this type is in a namespace (which is the case 99.99% of the time) then this single statement because a lot longer due to the fact that the ASP page has no concept of class scope so all of my types need to be fully qualified.</p>
<pre><code><%#((RootNamespace.SubNamespace1.SubNamspace2.SubNamespace3.MyType)Container.DataItem).PropertyOfMyType%>
</code></pre>
<p>Is there any kind of "using" directive or some equivalent I could place somewhere in an ASP.NET page so I don't need to use the full namespace every time?</p>

4,076,259 | 4,076,260 | Understanding the process of initialization | <p>This is my attempt to understand how class initialization works. I'm not sure about everything, and that is why I'm asking this question. This is what I believe happens when we do the following:</p>
<pre><code>T t = u;
</code></pre>
<ol>
<li><p>Constructs an object of type <code>T</code> from <code>u</code>. This then becomes:</p>
<pre><code>T t = T(u);
</code></pre></li>
<li><p>Calls the copy-constructor:</p>
<pre><code>T t( T(u) );
</code></pre></li>
</ol>
<p>Okay the second is the part I'm not understanding. I read somewhere that <code>T t = u</code> is made into <code>T t(T(u))</code>. But if that is true why doesn't this print "copy-constructor":</p>
<pre><code>struct T
{
template <class U>
T(U) {
std::cout << "constructs an object of type T...\n";
}
T(T const &)
{
std::cout << "copy-constructor";
}
T& operator=(T const &)
{
std::cout << "assignment operator"; return *this;
}
T() = default;
};
int main()
{
T t(T(5));
}
</code></pre>
<p>Actually, all this does is print "constructs an object of type T". Why isn't the copy-constructor called here? <code>T(5)</code> can be made into an object of type <code>T const &</code> which is passed into the constructor of <code>T</code> so shouldn't the appropriate constructor be called.</p>
<p>I'd really like some insight to this. I've been trying to understand this for a while.</p>

2,197,005 | 2,197,006 | I don't understand the usefulness of parameter arrays? | <p>Parameter arrays allow a variable number of arguments to be passed into a method:</p>

1,611,985 | 1,611,986 | sqlite with android no such table | <p>I have been testing my app which uses the dbadapter from Reto Meir's earthquake example. Everything was going ok for several days but when debugging with the app on the device today I got the 'no such table' error. I changed the name of the database and all runs well again. This doesn't give me much confidence regarding potential other users.</p>
<p>Since it seems impossible to see the database on the phone, by design I suppose, I can't see how to find out what caused the problem and take steps to avoid it. The database appears to open ok at the start of the program but errors when handling a select query. Just changing the name of the table doesn't fix it, it has to be a new database name.</p>
<p>As the change of name allows it to run ok I can't see that the code is wrong. I wonder if the data becomes corrupted.</p>
<p>I've also found that after successfully inserting a row, then later getting a cursor to allitems sometimes produces a -1 error against a get for one of the column names. How can a column name drop out of the columns index?</p>
<p>I've googled this type of problem and whilst there are a lot of folks with the problem and a lot of replies I can't find anything which informs on the underlying reason for these problems - which is what I am after. </p>

<p>I use a text file that contains email messages and split the tokens using regex, storing these values into a hashmap.</p>

[email protected]</p>
<p>regex causes the token to be:
john
smith
example</p>
<p>The same holds true for ip addresses, so for example, instead of:

5,533,404 | 5,533,405 | LinkedList...inheritance...what? | <p>I don't understand what this homework is asking me to do...</p>
<p>In our last project, we created a person.java class that made an array of people (or just instances of people)...and it had their ID, their mom, their dad, birthdate, number of children, and an array of their children. It had predictable methods like get or set mom and dad, add child, remove child, unset mom or dad, boolean to see if another instance is or is not a child of this instance, get sex, get id...i think that was it.</p>
<p>Anyway...the point of this project is to make small changes to our last project to allow unlimited number of children for each person class. The last project had a static int variable for the maximum number of allowable children set to 10.</p>
<p>To do this, we're to implement a list. And create another class called personlist.java, which is to be a sublcass of java.util.LinkedList. We have to make sure to save Person.java in the same project where we create PersonList.java so that the compler can recognize java.util.LinkedList. The PersonList class should transparently handle all methods related to adding/removing/finding the children of a person. Since PersonList is a subclass of LinkedList, we will have all the LinkedList methods available to us.</p>
<p>I don't even know where to start. I still have my Person.java class. I'm using Eclipse...so I made a new project. Made a class called PersonList.java. Made another class called Person.java and copied my old project into it.</p>
<p>How do I declare the new class so that it "communicates" with Person.java?</p>
<pre><code>import java.util.LinkedList;
public class PersonList extends LinkedList<Person> {
}
</code></pre>
<p>Is that right? I'm also confused as to why we weren't told to just modify Person.java to utilize linked lists. I can do that. Why create another class called PersonList.java? And what the heck goes in there? How do I call methods in PersonList.java from Person.java?</p>
<p>Any insight would be greatly appreciated!</p>

948,476 | 948,477 | Writing data from different classes to a text file using BufferedWriter | <p>I am working with Java.</p>
<p>I have created one text file. In that text file, I want one value to be stored in the text file from class1. Then I want one more value to be stored in the textfile from class2 on the 2nd line. Then I want one more value to be stored in line 3 of the text file from class 3 , etc. The text file, when retrieved, should look like this:</p>
<pre><code>77
65
34
</code></pre>
<p>The problem I encounter is that, the text file content gets erased when I move on to the next class. For example, the text file would only show the last data value. And erase the previous ones (in the example above, only 34 would appear that too on the first line, when it should be on the 3rd line). </p>
<p>Some code from class1:</p>
<pre><code>BufferedWriter outputFile0=null;
try {
int x = value_MAP();
FileWriter fwriter0 =new FileWriter("MAP_allData.txt");
outputFile0 = new BufferedWriter(fwriter0);
outputFile0.write(""+x);
outputFile0.newLine();
} catch( Exception y ) {y.printStackTrace();}
</code></pre>
<p>Same code again appears in class2, class3, etc:</p>
<pre><code>BufferedWriter outputFile0=null;
try {
int x = value_MAP();
FileWriter fwriter0 =new FileWriter("MAP_allData.txt");
outputFile0 = new BufferedWriter(fwriter0);
outputFile0.write(""+x);
outputFile0.newLine();
} catch( Exception y ) {y.printStackTrace();}
</code></pre>
<p>So is there a way to tell Java that dont worry about erasing the data, just add data one line after another when traveling from class 1 to class x. </p>

1,753,150 | 1,753,151 | Class construct causes the same code to be executed multiple times | <p>let me introduce you first to the issue that I am experiencing. I've recently started working on my own MVC framework. I want some additional experience and to understand how exactly framework's like CodeIgniter work.</p>
<p>Anyway, everything was going great until I added a construct to my controller. The request was routed properly, the controller has been initialized - the issue is that is gets initialized time after time and continues until resource limit has been reached.</p>
<p>After doing a lot of debugging, I found out that one simple line causes everything, but I don't know how why. This is the line:</p>
<pre><code>$controller = &FuturoContainer::getController();
</code></pre>
<p>To explain the above line. FuturoContainer is my implementation of dependency injection. It contains instances of all classes that should be initialized only once.</p>
<p>This is getController() method:</p>
<pre><code>private static $controller = null;
public static function &getController()
{
if (self::$controller === null) {
/* Load controller file */
require self::getParam('controllerFile');
$controllerName = self::getParam('controllerName');
self::$controller = new $controllerName;
}
return self::$controller;
}
</code></pre>
<p>$controller is null by default.</p>
<p>As I have already mentioned, even though $controller should be a class instance after this method has been executed for the first time, it seems to remain NULL. Not only that, but the method gets executed time after time after time. And the weirdest part: it only happens if I add __construct() to a controller like this:</p>
<pre><code>class Home extends Controller
{
public function __construct()
{
parent::__construct();
}
}
</code></pre>
<p>Any idea why might this happen? Thanks in advance.</p>
