4,409,130 | 4,409,131 | Remove object from list by identity | <p>In the following example a std::list stores objects of type Resource (by value, not pointing to). The Resource class does not provide a less than comparison nor equality operator. What is a good way to remove an object by identity (aka memory address). Can i avoid O(n) somehow? Is std::list the right container?</p>
<pre><code>// Definition of the container
std::list<Resource> resources;
// Code
Resource *closedResource = resourceFromList();
for (std::list<Resource>::iterator it = resources.begin(); it != resources.end(); ++it)
{

{

}
}
</code></pre>
<p><strong>Edit:</strong> Assume that the Resource class implements move semantic. Furthermore the Resource reregisters itself for any "movement" by a kind of Selector (cp. epoll or java.nio.Selector) for event notifications.</p>

<pre><code> var $myrows = $(".mydiv table tr").slice(index);
$($myrows , this).jQueryFunction()
</code></pre>
<p>The code is working fine, but I think $(".mydiv table tr") will make the browser traverse total DOM, so should I go for
$(".mydiv table tr",this).jQueryfunction() //I think this will improve performance,instead of using var$myrows.</p>
<p>I think 2 nd one is good.</p>
<p>2.$(".mydiv .indiv a",this).click(function(event)
this click is not working , if I remove this it will start working.why?</p>
<p>3.I have to select one specific tr, for that I am using </p>
<p>$(".mydiv table tr:nth-child(that specific child)")
Any better way of doing this?Also in this case it will traverse the DOM.
Thanks.</p>

<p>Hi All,
As a bit of a side project while I'm on my summer break from uni, I've decided to have a look at C++, and get the hang of the basics.</p>
<p>I'm by no means a programming novice, I've done web development before with PHP and Ruby, and I've done a fair bit of work with compiled languages (Java / C#). However, C++ seems to be a more significant undertaking. Basically I'm wanting pointers to the best resources for learning C++, as well as some idea as to areas I could do with reading up on (That I might not have come across before).</p>
<p>Any help would be hugely appreciated.</p>
<p>Thanks</p>

<p>When <code>insert</code> is called with <code>root</code>, I need <code>root</code> to be passed as a reference so as to change its value.

<p>I have a time stamp of 2010-07-26 23:35:03 </p>
<p>What I really want to do is subtract 15 minutes from that time.</p>
<p>My method was going to be a simple conversion to unix time, subtract the seconds and convert back. Simple right?</p>
<p>My problem is that python adjusts the returned unix time using my local timezone, currently eastern daylight savings time which I believe is GMT -4. </p>
<p>So when I do this:</p>
<pre><code> # packet[20] holds the time stamp
unix_time_value = (mktime(packet[20].timetuple()))
</code></pre>
<p>I get 1280201703 which is Tue, 27 Jul 2010 03:35:03. I can do this:</p>
<pre><code> unix_time_value = (mktime(packet[20].timetuple())) - (4 * 3600)
</code></pre>
<p>but now I have to check for eastern standard time which is -5 GMT and adjust the (4 * 3600) to (5 * 3600). Is there any way to tell python to not use my local timezone and just convert the darn timestamp OR is there an easy way to take packet[20] and subtract 15 minutes?</p>
