<p>I don't understand how this code even compiles.</p>
<p>Looks like each math expression with null returns <code>Nullable<T></code> (e.g. <code>10 / null</code> is a <code>Nullable<int></code>). But I don't see operator methods in <code>Nullable<T></code> class. If these operators are taken from <code>int</code>, why the last assertion doesn't fail?</p>

<p>How is that storage actually assigned to the application? Just by package name or also somehow bound to the sign key of the app?</p>
<p>Let's say I have installed application 1 and then write another application 2 with the same name and package name (just differently signed with different keys) and install it (app 2 replacing app 1), would that application 2 get access to the /data/data/[app]/files ?</p>
<p>Or would I not even be able to replace app1 with app2 due to different sign keys in the first place?</p>

FIXED: I fixed it by moving the code to the HTML head, removing it from the Smart html template file. Seems smarty messed it up in some way. Thx for your help :]
// Edit</p>
<p>How do I correctly add a parameter to a link with jquery? I've now read various threads here about that, but I can't get it to work right. </p>
<p>In detail, if the user clicks a certain link on click I want to get the value of an input, afterwards add it to the clicked link and redirect the user with the new url with the added parameter.</p>
<p>Everything works just fine, but when I dump the $_GET with Php on the target URL I always end up with amp;parameter_name instead of parameter_name. What I do:</p>
<pre><code>$('#add-item-wishlist').bind('click', function(e) {
// get quantity from input
var current_qty = $('.inp-qty').val();
//redirect user
e.preventDefault();
window.location.href = $(this).attr("href") + '&qty=' + current_qty;
});
</code></pre>
<p>&qty always results in amp;qty if I dump with php, so does the check inside the php script fail.</p>

<p>Hi
I'm trying to call a property in a class, that is inherited from my baseclass, but it doesn't work. I guess I'm missing something, but what?
Here is my code:</p>
<pre><code>class Produkt:
def __init__(self,pID,pProdNavn,pNetto):
self.__produktId = pID #atributt for produkt nummer
self.__produktNavn = pProdNavn #atributt for produkt navn
self.__produktNetto = pNetto #egenskap for nettopris
def getName(self): #Metode for å finne produktnavnet
return self.__produktNavn
class Bok(Produkt):
def __init__(self,pID,pProdNavn,pNetto,pForfatter):
Produkt.__init__(self,pID,pProdNavn,pNetto)
self.__produktForfatter = pForfatter #atributtp for forfatter
def getNet(self):
return self.__produktNetto
</code></pre>
<p>as you see I'm trying to call the _productNetto property that is inherited from my Produkt class.</p>
<p>What am I doing wrong?</p>
<p>/Andy</p>

2,685,062 | 2,685,063 | What exactly should be set in PYTHONPATH? | <p>I'm going through and writing a setup doc for other developers at work for a python project and I've been reading up on the <code>PYTHONPATH</code> environment variable. I'm looking at my current development system and think I have a few things set wrong that is causing my IDE (IntelliJ) to behave incorrectly when looking up the python libraries.</p>
<p>I've looked at the documentation <a href="http://docs.python.org/using/cmdline.html#envvar-PYTHONPATH" rel="nofollow">here</a> and <a href="http://stackoverflow.com/questions/859594/cant-find-my-pythonpath/859672#859672">here</a> and I'm still unsure of what should actually be in the <code>PYTHONPATH</code> environment variable. </p>
<p>I have <code>PYTHONHOME</code> pointed to `C:\Python27'.</p>
<p>My current <code>PYTHONPATH</code> is set to <code>PYTHONHOME</code>. Should I also add the directories from <code>sys.path</code>?</p>
<p>UPDATE:</p>
<p>Based on the below information, <code>PYTHONPATH</code> does not need to be set unless there are non-standard libraries that you want python to be able to find by default. For instance, when I install <a href="http://www.wxpython.org" rel="nofollow">wxPython</a> from the installer it will add its libraries to <code>PYTHONPATH</code>. I do set <code>PYTHONHOME</code> to the root of the python installation so that I can add it to my system <code>PATH</code> environment variable so that I can run python from any where.</p>

<p>I tried </p>
<pre><code>$("tr:has(td.special)");

<p>but that gives me (1) and (2), because :has means "has somewhere among all my descendants".</p>

<p>At the startup of the application I am writing I need to read about 1,600,000 entries from a file to a <code>Dictionary<Tuple<String, String>, Int32></code>. It is taking about 4-5 seconds to build the whole structure using a BinaryReader (using a FileReader takes about the same time). I profiled the code and found that the function doing the most work in this process is <code>BinaryReader.ReadString()</code>. Although this process needs to be run only once and at startup, I would like to make it as quick as possible. Is there any way I can avoid <code>BinaryReader.ReadString()</code> and make this process faster?</p>
