2,935,181 | 2,935,182 | Why do multiple iterations of a block of code increase average running time so much? | <p>For example, I'm running a simple nested loop that finds duplicate elements in two arrays. With a list size of 2000, it takes somewhere around 25 milliseconds on average (a guess) if I run the program several times in a row. However, running the program once within a for loop, the more times I loop it, the faster the average runtime for one iteration is. e.g. 10 times is 5 milliseconds each iteration, 10000 times is 2 milliseconds.</p>
<p>I have to measure the running time for a few different types of list intersection (e.g. nested loops, binary search etc.) at various list sizes, so I'm not sure which is more accurate. It becomes more of a problem for the longer ones because it takes too long to run it so many times.</p>

2,033,511 | 2,033,512 | Referring to objects inside a list without using references or indices | <p>I'm using python for my shopping cart class which has a list of items. When a customer wants to edit an item, I need to pass the JavaScript front-end some way to refer to the item so that it can call AJAX methods to manipulate it.</p>
<p>Basically, I need a simple way to point to a particular item that isn't its index, and isn't a reference to the object itself.</p>
<p>I can't use an index, because another item in the list might be added or removed while the identifier is "held" by the front end. If I were to pass the index forward, if an item got deleted from the list then that index wouldn't point to the right object.</p>

3,800,043 | 3,800,044 | Are there any good hands-on Javascript project tutorials? | <p>I have been studying javascript for a couple of months, and I have the basics down but I feel that I cannot really improve to a professional level on my own. I mean I can write simple code that accomplishes what I want, but it is no good code and I lack in understanding when talking to "professional javascripters". It is very hard to improve if you don't know what you don't know if you know what I mean. What I think is the best and fastest way to learn a programming language is to follow professionals when they work on real projects and have them explain along the way what they are doing and why. Two of the best examples here are "Agile web-development with rails" for learning rails and "the iOS apprentice series" for learning ios programming. Here you learn the programming language from following professionals as they are developing a real project and have them explain along the way. But now when it comes to javascript books and videos the majority that I have come across follow the school approach of first describing the whole language in theory and then giving you small exercises, which in my opinion is a very bad approach to teaching a craft. I don't really feel that comfortable with reading source code at my stage either, I would rather have explanations along with the code like you get in a good tutorial.</p>
<p>I have also read a lot of posts here on stack when it comes to book recommendations for learning javascript, but I think my specific question has not been asked yet. So please if you know any good resources that are hand-on like I described above, let me know. Also it doesn't matter if it is client side javascript or node.js projects.</p>

<p>I am undertaking a java project and the purpose behind it is to learn and practice java programming as I am new to it. I understand that albeit there is no set way of writing programs and every programmer has there own style. But you can get into bad programming habits such as bad styling, using inappropriate syntax for e.g not turning enough design problems into classes or maybe creating too many classes ,reinventing the wheel, Not using the right design patterns or maybe even the correct algorithms. So my question is how do I become a good java programmer rather then just someone who can write code?</p>

<p>Since Push Notifications will only be coming with OS 3.0, I've been thinking of using Email Pushs (Exchange, mobile.me) as a workaround:</p>
<p>You can register a URL, eg. myxyappname:// for your own app in iPhone. (See examples @ developer.apple.com/iphone)</p>
<p>If you have a server and want to push something app-specific to your subscribers, you can just send them an email containing a specific link, eg. myxyappname://myxyappname?requesttype=X&id=Y</p>
<p>When the user receives the email (pushed, so should be fast...) and clicks on the mentioned link, your app will start on the iPhone automatically (if your app registered the url correctly), and within your app you can parse the url and display the corresponding info, based on the query string.</p>

4,849,781 | 4,849,782 | jquery-ui: creating a customized collapsablility function | <p>I am trying to create <code><caption></code> tags that are, by default, uncollapsed but which, as an "onclick" property, can be collapsed. I'd also like for the expansion/collapsing to animate very slightly—I'd like for them to "unfold" or transition vertically downward when expanding and to transition vertically upward when collapsing. </p>
<p>Currently I am using:</p>
<pre><code>jQuery(document).ready(function(){
$('.cv .collapsable').click(function() {
$(this).next().toggle('slow');
return false;
}).next().hide();
});
</code></pre>
<p>However, this animates the <em>presentation of the content</em> within the collapsed <code><caption></code> rather than the unfolding of the parent element. I would really like to see the parent element expanding downward before the content of the element is displayed (or would be equally satisfied with the content of the element becoming visible as the element expands). Either way the issue is that the expansion is instantaneous and a bit jarring, whereas, once expanded, the content fades in gently.</p>
<p>Additionally, this function defaults to a collapsed state rather than an expanded one, and I need it to do the inverse. Basically, I want people to be able to collapse this to conserve screen real-estate if need be, but to otherwise have a normal and complete display of all the content between each <code>caption</code> tag. I'm sure this is very simple, I am complete <em>jquery</em> nub.</p>

4,009,014 | 4,009,015 | Using Response.Redirect() to a relative path | <p>I'm working with ASP.net. My website is hosted within a subfolder <code>test</code> under the IIS root directory. So the url of default.aspx is <code>http://localhost/test/Default.aspx</code>. From default.aspx, I want to use <code>Reponse.Redirect()</code> with a relative path to redirect to another url within the same web site, <code>http://localhost/test/whatever</code>.</p>
<p>I tried </p>
<pre><code>Response.Redirect("/whatever");
</code></pre>
<p>and </p>
<pre><code>Response.Redirect("~/whatever");
</code></pre>
<p>Both of them redirect to <code>http://localhost/whatever</code>. Note that the <code>Redirect</code> method use <code>http://localhost</code> instead of <code>http://localhost/test/</code> as the base url. </p>
<p>Any ideas?</p>
<p>Thanks.</p>
