Why doesn't `index = index++` increment `index`?
|
<p>** Dup: <a href="http://stackoverflow.com/questions/226002/whats-the-difference-between-x-x-vs-x">http://stackoverflow.com/questions/226002/whats-the-difference-between-x-x-vs-x</a> **</p>
<p>So, even though I know you would never actually do this in code, I'm still curious:</p>
<pre><code>public static void main(String[] args) {
int index = 0;
System.out.println(index); // 0
index++;
System.out.println(index); // 1
index = index++;
System.out.println(index); // 1
System.out.println(index++); // 1
System.out.println(index); // 2
}
</code></pre>
<p>Note that the 3rd <code>sysout</code> is still <code>1</code>. In my mind the line <code>index = index++;</code> means "set index to index, then increment index by 1" in the same way <code>System.out.println(index++);</code> means "pass index to the println method then increment index by 1".</p>
<p>This is not the case however. Can anyone explain what's going on?</p>

Date field change event with the calendar control
|
<p>When I bind the change event to a date field (using jQuery), it works fine if I type something in the field; as soon as I leave the field my event handler fires. The problem is that if the date is changed using the graphical calendar widget control, the event does not fire. Does anyone have a suggestion for how I can make this work? Thanks</p>

What makes sets faster than lists in python?
|
<p>The python wiki says: "Membership testing with sets and dictionaries is much faster, O(1), than searching sequences, O(n). When testing "a in b", b should be a set or dictionary instead of a list or tuple."</p>
<p>I've been using sets in place of lists whenever speed is important in my code, but lately I've been wondering why sets are so much faster than lists. Could anyone explain, or point me to a source that would explain, what exactly is going on behind the scenes in python to make sets faster?</p>

Sorting positions in Java
|
<p>I don't know how to put the question forth but i think an example might go a long way in clearing up the question....so here it is:</p>
<p>Say i have an array of strings: "Bob" "Alan" "Conrad" "Alice" "Alex".</p>
<p>After sorting alphabetically the array will become:"Alan" "Alex" "Alice" "Bob" "Conrad".</p>
<p>So we know in this case that the sorted element starting from "B" will be positioned after position number 3.</p>
<p>Now my question is,is there an inbuilt function in java/android which will let me know after the sorting where one group ends and the other starts (At which position the string transitions from "A" to "B")? </p>
<p><strong>EDIT</strong>: Or maybe even two different functions used in conjunction</p>

How to copy or duplicate an array of arrays

<p>I'm trying to make a function that duplicates an array of arrays. I tried blah.slice(0); but it only copies the references. I need to make a duplicate that leaves the original intact. </p>
<p>I found this prototype method at <a href="http://my.opera.com/GreyWyvern/blog/show.dml/1725165" rel="nofollow">http://my.opera.com/GreyWyvern/blog/show.dml/1725165</a></p>

for (i in this) {
if (i == 'clone') continue;
if (this[i] && typeof this[i] == "object") {
newObj[i] = this[i].clone();
} else newObj[i] = this[i]
} return newObj;
};

Java value object comparison methods
|
<p>I'm new to Java and trying to learn.</p>
<p>Java doesn't have operator overloading, so when coding a value object I understand that you need to compare objects with an overridden 'equals' method instead of the == operator, but I have yet to read about the other methods you need to override. What about the equivalent methods for the other common operators: >, <, >=, and <=. Do these methods need to be overridden, or do I have to create them if I need them. If I have to create these methods, there must be some standard naming convention for them ('gt', 'lt', 'gte', 'lte'). What is it?</p>

iPhone - Transparent status bar does not resize subviews
|
<p>I have two viewcontrollers in my app, one of them shows an opaque status bar (default) while the other shows a black translucent status bar.</p>
<p>When I come from the first view controller to the other, in viewWillDisappear of controller1, I specify this</p>
<pre><code>[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent animated:YES];
</code></pre>
<p>The autoresizing mask of controller2 is set as follows</p>
<pre><code>self.view.autoresizesSubviews = YES;
self.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
</code></pre>
<p>But even then, when controller2's view appears, the view begins from right below the status bar. I see a white space below the status bar. When the status bar is hidden after 3 seconds, the view adjusts and covers the white space. When the view is again tapped to show the status bar, the view shifts down to leave white space below the status bar.</p>
<p>Can someone please let me know how to resolve this.</p>
<p>Thanks.</p>
<p><strong>More Info</strong></p>
<p>This is only a problem with 3.x. With 2.2.1 the same code works fine and the view starts from behind the status bar.</p>

Use PHP to track links

<p>I have various links in my website that point to a specific form.</p>
<p>Whenever someone fills out the form, I want to be able to know what link led them to the form.</p>
<p>I want to do this without having to create an individual line of PHP code for every link I create in the. Instead, I want to have some PHP code that picks up something from that link, and maybe inserts it into a hidden text box that gets its value or text from something that I tag in the link.</p>
<p>For example:</p>
<ol>
<li>User clicks a link.</li>
<li>That link directs them to a form.</li>
<li>The link carries an identification that activates PHP code</li>
<li>When I recieve the form, I know what link was clicked to get to that form.</li>
</ol>
<p>I want it to work with links in emails I send out as well.</p>

Duplicate functionality of Android's built-in SMS app (image in-line with text)
|
<p>I'd like to make an app that duplicates the functionality of Android's SMS app. Specifically, I need it to do this:</p>
<ol>
<li>Have an EditText box that the user can key in text to.</li>
<li>Display an option image in said box.</li>
<li>Be able to interact with image, including selecting it to view/delete and backspacing to delete image.</li>
</ol>
<p>I know how to embed an image into an EditText using both the setCompoundDrawables and using SpannableString. The problem is that neither of them allow me to interact with the image, other than deleting it --- but even this is odd, because text I type ends up being "eaten" by the 60x60 dp image unless I first hit the enter key to line feed.</p>
<p>Is there a more proper way to do this?</p>

In Python, is there a good "magic method" to represent object similarity?
|
<p>I want instances of my custom class to be able to compare themselves to one another for similarity. This is different than the <code>__cmp__</code> method, which is used for determining the sorting order of objects.</p>
<p>Is there an magic method that makes sense for this? Is there any standard syntax for doing this?</p>
<p>How I imagine this could look:</p>
<pre><code>>>> x = CustomClass("abc")
>>> y = CustomClass("abd")
>>> z = CustomClass("xyz")
>>> x.__<???>__(y)
0.75
>>> x <?> y
0.75
>>> x.__<???>__(z)
0.0
>>> x <?> z
0.0
</code></pre>
<p>Where <code><???></code> is the magic method name and <code><?></code> is the operator.</p>

Do we ever need to use Iterators on ArrayList?
|
<p>Yesterday, when I was answering to question <a href="http://stackoverflow.com/q/15822810/2236253">getting ConcurrentModificationException error while using iterator and remove</a> I added a notice that</p>
<blockquote>
<p>It's not a good idea to use iterators when you have ArrayLists.</p>
</blockquote>
<p>You do not need to deeply understand that question to answer on that one.</p>
<p>There, I got two comments that I'm wrong.</p>
<p>My arguments:</p>
<ol>
<li><p>The code is much less readable with iterators.</p></li>
<li><p>There is a possibility to raise ConcurrentModificationException that is hard to debug.</p></li>
</ol>
<p>Can you please explain?</p>

Is this javascript encoding properly written?
|
<p>I have tried some tips I was given on regards URL encoding but I have no success so far. First, I was given this format, </p>
<pre><code>var url = "http://www.polyvore.com/cgi/add?title="
+ encodeURIComponent(%%GLOBAL_ProductName%%)
+ "&url=" + encodeURIComponent("http://lilaboutique.co.uk/products/"
+ encodeURIComponent(%%GLOBAL_ProductName%%)
+ "&imgurl=" + encodeURIComponent(%%GLOBAL_ThumbImageURL%%)
+ "&desc=" + encodeURIComponent(%%GLOBAL_ProductDesc%%)
+ "&price=" + encodeURIComponent(%%GLOBAL_ProductPrice%%));
</code></pre>
<p>which never got to be passed to the href dunno for what reason. Then I played with it some more, </p>
<pre><code>var url = "http://www.polyvore.com/cgi/add?title=encodeURIComponent(%%GLOBAL_ProductName%%)&url=http://lilaboutique.co.uk/products/encodeURIComponent(%%GLOBAL_ProductName%%)&imgurl=encodeURIComponent(%%GLOBAL_ThumbImageURL%%)&desc=encodeURIComponent(%%GLOBAL_ProductDesc%%)&price=encodeURIComponent(%%GLOBAL_ProductPrice%%)";
</code></pre>
<p>this time the url was passed but the values were mixed between the appropriate and other fields displaying the encoding function itself. </p>
<p>Any help clarifying my mistakes is greatly appreciated. I would like to encode just price and description, seems to be the fields giving problems. </p>
<p>A regular link does render without problems</p>
<pre><code>var url = "www.google.com";
var myAnchor = document.getElementById('myAnchor');
myAnchor.href = url;

Server side validation
|
<p>I am having an issue with the requiredfieldvalidator control not working on an ASP.net page. I have completed the attributes of that field properly, but when I test it, the postback is allowed to happen even if the field in question is blank. </p>
<p>So I want to do server side validation instead. What is the best way to do that? In the event that caused the postback? Also, if I find out the field is blank, how do I get the user back to the screen with all other values they placed on other fields intact and a message saying "This field cannot be blank".</p>
<p>EDIT:</p>
<p>This is the code:</p>
<pre><code><asp:TextBox ID="fName" TabIndex="1" runat="server" Width="221px" CausesValidation="True"></asp:TextBox>
<asp:RequiredFieldValidator ID="FNameRequiredFieldValidator" runat="server" ControlToValidate="fName" InitialValue="" ErrorMessage="Filter Name cannot be blank." ToolTip="Filter Name cannot be blank.">*</asp:RequiredFieldValidator>

}
long ftime = time - Util.lastTime;
Util.lastTime = time;
return ftime;

if(lastTime > 1000){
return;
}
System.out.println(lastTime);

Voodoo Code In Python
|
<p>I was going through Zed Shaw's Learn Python The Hard Way and something in Chapter 15 struck me. In the extra credit exercises he asks us to delete the latter part of the code [everything after print txt.read() ] and then execute it, but the interpreter behaves as if nothing has happened. Yes, I saved the file and when I modified it by adding print statements then the changes still showed up, but the same voodoo code was executed. Why?</p>
<p>What's going on over here?</p>
<pre><code>from sys import argv
script, filename = argv
txt = open(filename)
print "Here's your file %r:" % filename
print txt.read()
print "I'll also ask you to type it again:"
file_again = raw_input("> ")
txt_again = open(file_again)
print txt_again.read()

issuing things to shell and forgetting about it in php
|
<p>how do you issue commands to the shell and then forget it's output and such? for example:</p>
<pre><code><?php
echo `sleep 2;echo hi`;
echo "foo";
?>
</code></pre>
<p>the result for this is hifoo. i would want a result that gives me foohi. why? i want the command issued to the shell simply issued and forgotten, i am confused about why PHP will wait for the result. is such a result possible?</p>
<p>(the idea behind this is setting up the correct number of selenium grid RC instances programatically. currently, it will stop after the first process is opened)</p>

<pre><code> <?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="hello">Hello World, Jain_aartisActivity!</string>
<string name="app_name">जैन आरती संग्रेह</string>
</resources>
</code></pre>
<p>But the AVD is unable to display the app_name. It just displays a small rectangle for each hindi character.</p>

Check where request came from
|
<p>on the site when an image is required the link is like this</p>
<pre><code><img src="getimage.php?id=<?php echo $name ?>" " width="280px" height="70px">
</code></pre>
<p>Then on getimage.php it gets the id and from that finds the right picture and displays it.</p>
<pre><code>$id = $_GET['id'];
</code></pre>
<p>This works perfectly. How would I find out where the request came from. So on which page this line below was on </p>
<pre><code><img src="getimage.php?id=<?php echo $name ?>" "width="280px" height="70px">
</code></pre>
<p>So ultimately I can know if the image requested is for index.php or about.php etc</p>

Should I separate my javascript code files based on line count?
|
<p>I custom coded a dynamic database linked (through asp.net) photo gallery in javascript which manages about 300 images. There is no redundant code, but it is about 500 lines long. Should I be splitting it into different .js files, or is the one .js file with 500 lines okay? Is there a best practice for ensuring that javascript files stay under a certain amount of lines of code?</p>

loop trough list of elements and update hidden field seperated by vertical line and comma

<p>Dear wise mans. Here is the problem</p>
<p>I can have a unlimited set of list items and form fields (limited) in li:</p>
<pre><code> <li id="apr1">
<textarea class="thisistext">blablabla</textarea>
<input class="imgid" type="hidden" value="450">
<input class="order" type="hidden" value="1">
</li>
<li id="apr2">
<textarea class="thisistext">bimbimbim</textarea>
<input class="imgid" type="hidden" value="455">
<input class="order" type="hidden" value="2">
</li>
etc
</code></pre>
<p>What I want is, write the contents of of all field in hidden field for update to database:
The format should be values from field seperated by comma and groups seperated by vertical line | </p>
<p>"imgid,order,thisistext|imgid,order,thisistext|etc... "</p>
<pre><code><input id="thedatafield" value="450,1,blablabla|455,2,bimbimbim| etc...">
</code></pre>
<p>How would you accomplish this? Probalby, the .serialize() would help, but the important part is textarea, which can be in pure html format.</p>
