3,593,468 | 3,593,469 | Are anonymous functions more effecient over calling functions? | <p>I'm just starting to learn about jQuery. I'm more of a html+css web designer so you can probably tell functions will take a little bit to adapt to, especially anonymous ones. </p>
<p>So what's the difference if between </p>
<pre><code>$('p.expander').toggle(
function() {
$(this).prev().addClass('open');
},
function() {
$(this).prev().removeClass('open');

);

<p>and say... </p>
<pre><code> function toggle1 () { $(this).prev().addClass('open');}
function toggle2 () { $(this).prev().removeClass('open');}
$('p.expander').toggle(toggle1, toggle2);
</code></pre>
<p>Do you use anonymous functions if you're using it once? And if you're going to use functions more than once, you should call it? </p>
<p>And as the title states, is one more effecient than the other? Because it seems like 99% of the articles use anonymous articles. I find it hard to read the code sometimes because I forget what a semicolon or parenthesis is for. </p>

bool lessThan = f("x<2");
}
public bool f(Expression expression)

public bool f(int x, char c, int y)
{
if(c == '<')
return x < y;
if(c == '>')

<p>Really what I'm getting at is a way to get around using a switch or series of if statements for each of: < > <= >= == !=. Is there a way to do it?</p>
<p>Edit: Suppose that the expression is a string, like "x < 2". Is there a way to go from the string to a predicate without using a series of if statements on the condition?</p>

731,503 | 731,504 | Recommendations for implicit versus explicit line joining | <p>I would like to know recommendations about <a href="http://docs.python.org/reference/lexical_analysis.html#implicit-line-joining">Implicit Line Joining</a> versus <a href="http://docs.python.org/reference/lexical_analysis.html#explicit-line-joining">Explicit Line Joining</a> in Python.</p>
<p>In particular, do you favor one form over the other? What do you recommend as the general default? What criteria do you have for choosing one over the other, and if you do have a preference of one, when do you make exceptions for the other?</p>
<p>I have an answer in mind for this question that reflects my own biases, but before I post my own answer I would like to know what others think... and if you can have a better set of criteria than what I have in mind, then I'll certainly accept your answer over my own.</p>
<p>Some of the recommendations may be generalized to this choice in other programming languages, but my own bias is somewhat stronger in Python due to some language-specific features, so I'd like to know both the general and the Python-centric reasoning you may have on this topic.</p>
<p>For some background, the discussion happened around a <a href="http://stackoverflow.com/questions/8626835/what-is-the-meaning-of-this-python-statement">particular question on stackoverflow</a>, but I thought it was more appropriate to move the discussion over to here as a question to avoid cluttering up the answer on SO with this tangent since it has veered off-topic from the original question. You can look at that question and its answers for the example code snippets that got the discussion going.</p>
<p>Here is a simplified example:</p>
<pre><code>join_type = "explicit"
a = "%s line joining" \
% (join_type)
# versus
join_type = "implicit"
b = ("%s line joining"
% (join_type))

<p>I think I can do in following way:</p>
<p>Create a HttpHandler(.ashx) to send appropriate image to client. So I can write a img in page like this: <code><img src=‘ImageHandler.ashx?id=foo.jpg’/></code>. App will check whether the image(<code>foo.jpg</code>) exists or not, then decides to send foo.jpg or default.jpg.</p>

<p>Here is a <a href="http://jsfiddle.net/c2J36/" rel="nofollow">jsFiddle</a> with the following code to demo</p>
<pre><code>$(document).ready(function(){
$("#textarea1").html("1234 <span id='span1' style='color:red'>5678</span>");
var offset = $("#span1").offset();
alert("span1 left: " + offset.left + " top: " + offset.top);
});
</code></pre>
<p>I see why the position of the span would be zero, relative to the textarea. But I don't understand why the offset is returning zero. If anyone could help me out here I'd appreciate it.</p>
<hr>
<p>Edit: My goal was to position something above the span when it was clicked. I couldn't get the offset of the span mentioned above, so I decided to use the mouse coordinates instead.</p>
<pre><code>$("#id").dblclick(function(e){
alert("X: " + e.pageX + " Y: " + e.pageY);

5,018,746 | 5,018,747 | PHP don't wait for response / reply return immediately | <p>I have a web service written in PHP to which an iPhone app connects to. When the app calls the service, a series of notification messages are sent to Apple's APNs server so it can then send Push Notifications to other users of the app.</p>
<p>This process can be time consuming in some cases and my app has to wait a long time before getting a response. The response is totally independent of the result of the notification messages being sent to the APNs server.</p>
<p>Therefore, I would like the web service to send the response back to the app regardless of whether the messages to APNs have been sent.</p>
<p>My current code:</p>
<pre><code><?
<...>
echo $chatID; // This has to be printed immediately
include('apns.php'); // Just invoke this, dont wait for response!
