Single word Palindrome Checker (True or False)
|
<p>Right now, what I have is a code that I can test a single word whether it is a Palindrome or not. I have to input the word, and it will tell me whether it is a Palindrome (True) or if it is not (False)</p>
<p>I need to create one that Asks for a single word, then provides a True of False based on the word that is typed. This is what i have so far. </p>
<p>I really have no idea how to do this, any help would be greatly appreciated. </p>
<pre><code>def isPalindrome(s):
if len(s) <= 1:
return True
else:
if s[0] != s[len(s)-1]:
return False
else:
return isPalindrome(s[1:len(s)-1])
print(isPalindrome("poop"))

<p>I've a textarea that has <code>keyup</code> event to show a preview of rendered input. However, I want to display the same preview immediately after the element is loaded.</p>
<pre><code>$('textarea[name="ay[description]"]').on('keyup', function(e){
</code></pre>
<p>The simplest of all is to initiate <code>.trigger('keyup')</code> at the end of the declaration. However, isn't there event such as <code>load</code>, <code>onload</code> or <code>ready</code> that I've missed under different name?</p>

Printing a square - cant find the error
|
<p>The work I am currently doing requires me to 'draw' a square by printing '*' as the outline and '.' to fill it in. My code seems to work but it still isn't accepting it. I am a beginner, thanks. </p>
<pre><code>class Main {
public static void main(String args[]) {
int square = 5;
int line = 1;
int stars = 1;
int startLine = square / square;
while (line <= startLine) {
while (stars <= square) { // first line prints out dots for the value of square, in this case 5
System.out.print("*");
stars = stars + 1;
}
System.out.println();
line = line + 1; //prints new line and adds 1 to line. Meaning it will move to the next section as it is now greater than startLine
}
stars = 1; //resets stars
while (line <= square - 1) {// line will keep looping until its value is greater than square - 1
while (stars <= startLine) {
System.out.print("*"); // First character to print is *
stars = stars + 1;
}
while (stars <= square - 1) {
System.out.print("."); //prints 3 dots
stars = stars + 1;
}
while (stars <= square) {
System.out.print("*"); // stars is equal to square so 1 star is printed
stars = stars + 1;
}
stars = 1;
System.out.println();
line = line + 1; // adds a value and loops around again
}
stars = 1;
while (line <= square) {
while (stars <= square) {
System.out.print("*");
stars = stars + 1;
}
System.out.println();
line = line + 1;
}
}
}
</code></pre>
<p>It seems to make up the square and if I change the value of 'square' the size changes too. I cant see the problem.</p>

Android's RGBToHSV method doesn't work
|
<p>According to <a href="http://developer.android.com/reference/android/graphics/Color.html#RGBToHSV%28int,%20int,%20int,%20float%5b%5d%29" rel="nofollow">the document</a>, android.graphics.Color has a method called <code>RGBToHSV</code> which can convert RGB values to HSV, this is what the document tells me:</p>
<pre><code>public static void RGBToHSV (int red, int green, int blue, float[] hsv)
</code></pre>
<blockquote>
<h3>Convert RGB components to HSV.</h3>
<ul>
<li><code>hsv[0]</code> is Hue [0 .. 360)</li>
<li><code>hsv[1]</code> is Saturation [0...1] </li>
<li><code>hsv[2]</code> is Value [0...1]</li>
</ul>
<h3>Parameters</h3>
<ul>
<li><em>red</em>: red component value [0..255]</li>
<li><em>green</em>: green component value [0..255]</li>
<li><em>blue</em>: blue component value [0..255]</li>
<li><em>hsv</em>: 3 element array which holds the resulting HSV components.</li>
</ul>
</blockquote>
<p>But when I write a program to test it, it doesn't work any way.</p>
<pre><code>float[] hsv = new float[3];
RGBToHSV(255, 255, 0, hsv);
Log.i("HSV_H", "" + hsv[0]); // always output 0.0
</code></pre>
<p>Is it a bug ? </p>

Best way to propagate opener variable across page navigation?
|
<p>Application that I'm working on has multiple modules. Two are of a concern - main module and module that I write. And I have to call a function on window that contains main module and the problem is that I have to call that function not from page that is opened by parent webmodule, but from page to which user navigates from this page. </p>
<p>Basically first page presents just some query forms, lets user to make some query, and second holds query results, and I am supposed to update contents of parent page based on these results. </p>
<p>Navigation goes like that</p>
<ul>
<li>Main module </li>
<li>First page of my module (i have main module page as an <code>window.opener</code> variable. </li>
<li>Second page of my module (and I would like to be able to open this page in the same browser window that the first one is opened)</li>
</ul>
<p>And I would like to have as free navigation as possible - like opening query results in new tab, going back changing query parameters, making new query, etc. I would also like to present user query forms on page that displays results and let them to refine this query, and still be able to update main module. </p>
<p>I was thinking of following solutions: </p>
<ol>
<li>Using AJAX to load query results to first window, but I would like to have this app as simple as possible, and AJAX is not simple ;)</li>
<li>Spawning new window on every request and doing code like <code>var mainModule = opener.mainModule</code>. Which is evil. </li>
<li>Embedding query results in a frame or iframe, but I havn'e got the slightest idea on how to inject main module window javascript variable into frame or iframe.</li>
</ol>

How does Android decide which layout folder to use?
|
<p>In my application I have 3 different layout folders:</p>
<pre><code>layout
layout-large
layout-xlarge
</code></pre>
<p>I did this according to the available Android device screens, described <a href="http://developer.android.com/guide/practices/screens_support.html#range" rel="nofollow">here</a>. So I thought that the screen size in inches is the only thing that is used to decide which layout folder to use. But recent tests with various 7 inch emulator showed that sometimes the <code>layout</code> and sometimes the <code>layout-large</code> folder is used. So can anybody tell me which other factors are used?</p>

<p><code>onclick</code> of <code>div</code> i make one function, and <code>onclick</code> on <code>img</code> - another. but when i click on <code>img</code> it make the first function too, because the <code>img</code> is in <code>div</code> element.
so, i think, that if there were something like <code>isClicked</code>, onclick of div i can just verify, if img is <strong>Not</strong> clicked ...</p>
<p>(i can write a logic, and verify it by so,for example onclick of img i can add a class to somebody... but maybe there is a function for it?)</p>

ProgressBar.setProgressDrawable not working for Android 2.3
|
<p>I am currently working with a dynamically updating <code>ProgressBar</code>. Through certain percentages, the progessbar sets a drawable of a different color. We currently have various colored clip drawable defined in a drawable xml. The one entitled <code>progressbar_blue_states</code> is detailed as follows: </p>
<pre><code><layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="@android:id/background"
android:drawable="@drawable/progressbar_grey">
</item>
<item android:id="@android:id/progress">
<clip android:drawable="@drawable/progressbar_blue" />
</item>
</layer-list>
</code></pre>
<p>Whenever we need to update the dialog, we call the following code:</p>
<pre><code>progressBar.setProgressDrawable(getResources().getDrawable(R.drawable.progressbar_blue_states));
</code></pre>
<p>However, not only does this not update the ProgressBar, but also it takes out the progress bar altogether where whitespace is left in it's place. However, if I set <code>android:progressDrawable="@drawable/progressbar_blue_states"</code> in the xml and take out this <code>setProgressDrawable()</code> call, it loads correctly. We need the setProgressDrawable to update the colors as needed. </p>
<p>This call works fine in Android 4.0+ however in Android 2.3 we're running into some trouble. Any ideas?</p>
<p><strong>Edit</strong></p>
<p>This is how we set up the ProgressBar in the xml:</p>
<pre><code><ProgressBar android:id="@+id/progress"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginBottom="2dp"
android:indeterminate="false"
android:indeterminateOnly="false"
android:progress="24"
android:max="100"
android:progressDrawable="@drawable/progressbar_red_states" />

How to get a file from ressource
|
<p>I know it seems like my question has been answered before, but I can't find an answer for my case.</p>
<p>What I am trying to do, is to get a File type from resource, so when it's packaged, it can be accessed. The answers I found were trying to read that file, but what I really need, is to construct a File object, because I have a third party library that is expecting that object.</p>
<p>Here is a the code I tried:</p>
<pre><code> String xslFilePath = new Test().getClass().getResource("/com/test/decision_template.xsl").getPath();
System.out.println(xslFilePath);
File xsltfile = new File(xslFilePath);
System.out.println(xsltfile.getAbsolutePath()+", exist:"+xsltfile.exists());
</code></pre>
<p>I got this result:</p>
<pre><code> C:\>java -jar test.jar
file:/C:/test.jar!/com/test/decision_template.xsl
C:\\file:\C:\test.jar!\com\test\decision_template.xsl, exist:false
java.io.FileNotFoundException: file:\C:\test.jar!\com\test\decision_template.xsl
(Syntaxe du nom de fichier, de rÚpertoire ou de volume incorrecte)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:120)
at com.test.Test.main(Test.java:30)
</code></pre>
<p>I need a way to get that file so the .exists() return true.</p>

C# functions and optional parameters
|
<p>I know that in C# it is possible to define optional parameters. My question is directed at how flexible this is.</p>
<p>Let f be a function as below, with <strong>a</strong> mandatory and <strong>b</strong>, <strong>c</strong> optional :</p>
<pre><code>class Test {
public void f(int a, int b = 2, int c = 3) {
//...
}
}
</code></pre>
<p>Now, I know I can call the function in the following ways :</p>
<p>f(1) -> a equals 1, b equals 2, c equals 3</p>
<p>f(11,22) -> a equals 11, b equals 22, c equals 3</p>
<p>f(11,22,33) -> a equals 11, b equals 22, c equals 33</p>
<p>How do I do to not specify <strong>b</strong>, but <strong>a</strong> and <strong>c</strong> ?</p>

Get selected element's outer HTML
|
<p>I'm trying to get the HTML of a selected object with jQuery. I am aware of the <code>.html()</code> function; the issue is that I need the HTML including the selected object (a table row in this case, where <code>.html()</code> only returns the cells inside the row).</p>
<p>I've searched around and found a few very ‘hackish’ type methods of cloning an object, adding it to a newly created div, etc, etc, but this seems really dirty. Is there any better way, or does the new version of jQuery (1.4.2) offer any kind of <code>outerHtml</code> functionality?</p>

int i;
string price_line = "";
string date_line = "";
List<decimal> prices = new List<decimal>();

using (var reader = new StreamReader(e.Result))
{
price_line = reader.ReadLine();
date_line = reader.ReadLine();
string[] bit_1 = price_line.Split(':');
string[] bit_2 = date_line.Split(':');
for (i = 0; i < 2; i++)
{
prices.Add(decimal.Parse(bit_1[i]));
dates.Add(bit_2[i]);
}
listBox1.ItemsSource = prices;
listBox2.ItemsSource = dates;

<p>I have cascading dropdowns (country/province/city). when the page posts back I lose the selected option for province and city. The options for country are loaded through .net code but the province and city options are populated through javascript.</p>
<p>I think this has something to do with viewstate but can't quite wrap my head around why the selected values aren't posting back.</p>

Using str_replace to remove spaces for exec()
|
<p>I'm running into an issue with the function <code>str_replace()</code> while trying to create a shell command in PHP. In shell, when I tab-finish a line that has spaces, it comes up like this:</p>
<pre><code>tar cvfz destination/filename.zip source/Name\ Of\ The\+\ Folder
</code></pre>
<p>So to me, this says that in order to run this command via <code>exec()</code>, I need to replace any spaces I would have in a string in PHP. To remedy this problem, I'm using</p>
<pre><code>$q = str_replace(' ', '\ ' , $q);
</code></pre>
<p>at the start of my string parse, in order to format the spaces into "\ " instead of " ". The issue I'm having is that for this particular folder, it's also removing the plus symbol as well, and it formats it like this:</p>
<pre><code>tar cvfz destination/Name\ Of\ The\ \ \ Folder.tgz source/Name\ Of\ The\ \ \ Folder
</code></pre>
<p>How can I set this up so <code>str_replace()</code> doesn't remove the plus sign? From my limited tests so far, it isn't removing anything out of these: <code>-, %, @, !, (, *, ), ^, =</code></p>

How to make my app full screen on Galaxy Tab
|
<p>I've been trying everything I can think of to get my app to display full screen on the Galaxy Tab.</p>
<p>Basically, it works like the Lunar Lander example app that comes with the Android SDK. What would you do to make that Lunar Lander app display in full screen on Large screen devices like the Galaxy Tab?</p>
<p>I'm not concerned about the quality of the graphics at this point, but just how an app created like this can fill the screen. It was basically designed to work on a 320x480 MDPI screen with images in the drawable folder and it uses a SurfaceHolder and view to draw the individual bitmaps.</p>
<p>Any advice?</p>
<p>CLARIFICATION: Sorry, I don't mean full screen as in removing the notification and title bar, I mean that everything has a giant black border around it and it the graphics don't take up the whole screen.</p>

How to correctly read attributes from android namespace in custom Preference?
|
<p>I am writing a custom <code>Preference</code>. I can easily read attribute values in my private namespace:</p>
<pre><code>public MyPreference(Context context, AttributeSet attrs)
{
super(context, attrs);
TypedArray styledAttrs = context.obtainStyledAttributes(attrs, R.styleable.MyPreference);
mDefaultValue = styledAttrs.getInt(R.styleable.MyPreference_defaultValue, 0);
}
</code></pre>
<p>But I do not know, how to read android attributes, e.g. <code>android:defaultValue</code>. In all examples on the web attributes contain values, but I use resources like <code>@integer/my_number</code> so simply reading <code>attrs</code> does not work - attribute contains resource reference but not the value. android.R.styleable is not accessible, so I do not understand how to do it.</p>

<pre><code>function Person(first_name, last_name) {
this.first_name = first_name

<p>Why is he using <code>Object.defineProperty</code> on <code>Person.prototype</code> and not simply on <code>Person</code>?
Why not simply include <code>name</code> in the definition or make <code>Person.name = bla...</code>?</p>

Abstract getter with concrete setter in C#
|
<p>I'm trying to write an abstract base class for read-only collections which implement <code>IList</code>. Such a base class should implement the set-indexer to throw a <code>NotSupportedException</code>, but leave the get-indexer as abstract. Does C# allow such a situation? Here's what I have so far:</p>
<pre><code>public abstract class ReadOnlyList : IList {
public bool IsReadOnly { get { return true; } }
public object this[int index] {
get {
// there is nothing to put here! Ideally it would be left abstract.
throw new NotImplementedException();
}
set {
throw new NotSupportedException("The collection is read-only.");
}
}
// other members of IList ...
}
</code></pre>
<p>Ideally <code>ReadOnlyList</code> would be able to implement the setter but leave the getter abstract. Is there any syntax which allows this?</p>

Python: Cut and Paste Data on Text File.
|
<p>I have a text file that contains numbers.</p>
<p>I need to move some of the numbers from the beginning of the file to the end in the correct order. </p>
<p>For example, the Original <code>TEXT</code> file has the following content: <code>0123456789</code>.</p>
<p>I need to move the <strong>first 4 numbers</strong> to the end in the same order so it'll look like this:</p>
<p><code>4567890123.</code> </p>
<p>Unfortunately i have no idea how to do this with Python,
I don't know even where to start. </p>

android updateThread draw() method and touchEvent interference
|
<p>I have a game which displays an array of colored blocks. The user can move these blocks around the screen. When a touch event occurs, I take note of the cell that has been touched (<code>cell[i][j].isMoving = true</code>). If the user moves the block around I draw the rectangle relative to an offset value. When a touch up event is detected, I check whether or not the user has dragged the block far enough to signify a moving of a block.</p>
<p>My basic draw loop is as follows:</p>
<pre><code>for(int i = 0; i < xCells, i++){
for(int j = 0; j < yCells; j++){
if(cell[i][j].isMoving)
canvas.drawRect(...) // draw with offsets
else
canvas.drawRect(..)
}
}
</code></pre>
<p>The problem I am having is when a user releases the block it occasionally flickers briefly.</p>
<p>When a touch up event occurs, the offset must be set to 0, the coordinates of the block changed (if requirements are met) and <code>isMoving</code> has to be set to <code>false</code>.
As I have a thread constantly running that calls the draw code above, it appears that the UI thread is altering the array of blocks, meaning it is in an inconsistent state when the draw method occurs.</p>
<p>Does anyone have suggestions on how to fix this? Could I use a handler? I've tried synchronizing the <code>onTouchEvent</code> method and the <code>onDraw</code> method, but this seems to occasionally block user input</p>
<p>thanks</p>

Dynamic iframe onload not firing?
|
<p>I figure this is possible because there are a ton of similar questions (that have been solved) but none seem to deal with dynamically created iframes.</p>
<p>Basically I'm using jquery to create a temp iframe to load files (from a file path served through an ajax call) to then open a file download prompt.</p>
<p>Everything works but to keep my DOM from being populated by a bunch of iframes I would like the iframes to be removed once the file is downloaded.</p>
<p>My iframe creation code:</p>
<pre><code>$('<iframe class="downloadIFrame" src="'+data['url']+'"></iframe>').appendTo('body');
</code></pre>
<p>And the code to destroy it (in the "ready" jquery event callback):</p>
<pre><code>$('.downloadIFrame').live('load', function() { alert('loaded');$(this).remove(); });
</code></pre>
<p>I don't get the alert that the iframe was loaded so it's not called. Any clue?</p>

Jquery sliding element down and up with the same link not working

<p>I have the following code, it slides down, but not up. Please could you help me find the error, and also if maybe there is a better way to do this, I have tried slideToggle, but that does not make it possible to check the state of the element, for where using hide and show you can check <code>$('#my_div').is(':hidden')</code>.</p>
<p>Here is my code:</p>
<pre><code>$("a.advanced_search_toggle").click(function() {
if ($("#advanced_search_box").hasClass('closed')) {
$("#advanced_search_box").slideDown(function(){
$("a.advanced_search_toggle").text('Simple Search');
$("a.advanced_search_toggle").removeClass('down_arrow');
$("a.advanced_search_toggle").addClass('up_arrow')
$("a.advanced_search_toggle").removeClass('closed');
$("a.advanced_search_toggle").addClass('open');

Movement in game programming
|
<p>This question may have been asked before, but I'm starting to get into game programming on the Android. I'm having a hard time figuring out the best way to move an object.</p>
<p>To put it simply, lets say I have a bitmap located on 0,0 and i want to move it across the screen. The obvious way to do it would be to simply increment the X position by one every time the Surface View onDraw method gets called.</p>
<p>But what if I wanted to make it move faster? I could increment it by two or three instead of one, but then the movement starts to get really choppy and stupid looking.</p>
<p>What is the best way to go about doing this?</p>

Initializing and assigning values,from pass by reference
|
<p>Okay, this is just a minor caveat. I am currently working with the lovely ArcSDK from ESRI. Now to get a value from any of their functions, you basically have to pass the variable, you want to assign the value to.</p>
<p>E.g.:</p>
<pre><code>long output_width;
IRasterProps->get_Width(&output_width);
</code></pre>
<p>Its such a minor thing, but when you have to pick out around 30 different pieces of data from their miscellaneous functions, it really starts to get annoying.</p>
<p>So what i was wondering is it possible to somehow by the magic of STL or C++ change this into:</p>
<pre><code>long output_width = IRasterProps->get_Width(<something magical>);
</code></pre>
<p>All of the functions return void, otherwise the off chance some of them might return a HRESULT, which i can safely ignore. Any ideas?</p>
<p><strong>*EDIT**</strong></p>
<p>Heres the final result i got which works :)!!!!!</p>
<pre><code>A magic(P p, R (__stdcall T::*f)(A *)) {
A a;
((*p).*f)(&a);
return a;
}
</code></pre>

Evaluate my Python server structure
|
<p>I'm building a game server in Python and I just wanted to get some input on the architecture of the server that I was thinking up.</p>
<p>So, as we all know, Python cannot scale across cores with a single process. Therefore, on a server with 4 cores, I would need to spawn 4 processes. </p>
<p>Here is the steps taken when a client wishes to connect to the server cluster:</p>
<p>The IP the client initially communicates with is the Gateway node. The gateway keeps track of how many clients are on each machine, and forwards the connection request to the machine with the lowest client count.</p>
<p>On each machine, there is one Manager process and X Server processes, where X is the number of cores on the processor (since Python cannot scale across cores, we need to spawn 4 cores to use 100% of a quad core processor)</p>
<p>The manager's job is to keep track of how many clients are on each process, as well as to restart the processes if any of them crash. When a connection request is sent from the gateway to a manager, the manager looks at its server processes on that machine (3 in the diagram) and forwards the request to whatever process has the least amount of clients.</p>
<p>The Server process is what actually does the communicating with the client.</p>
<p>Here is what a 3 machine cluster would look like. For the sake of the diagram, assume each node has 3 cores.
<img src="http://img152.imageshack.us/img152/5412/serverlx2.jpg" alt="alt text" /></p>
<p>This also got me thinking - could I implement hot swapping this way? Since each process is controlled by the manager, when I want to swap in a new version of the server process I just let the manager know that it should not send any more connections to it, and then I will register the new version process with the old one. The old version is kept alive as long as clients are connected to it, then terminates when there are no more.</p>
<p>Phew. Let me know what you guys think.</p>

How to tell if item in list contains certain characters
|
<p>I have a script that creates a list of numbers, and i want to remove all numbers from the list that are not whole numbers (i.e have anything other than zero after the decimal point) however python creates lists where even whole numbers get .0 put on the end, and as a result i cant tell them apart from numbers with anything else. I can't use the int() function as it would apply to all of them and make them all integers, and then i'd lose the ones that originally were.</p>
<p>Here is my code:</p>
<pre><code>z = 300
mylist = []
while(z > 1):
z = z - 1
x = 600851475143 / z
mylist.append(x)
print(mylist)
[y for y in mylist if y #insert rule to tell if it contains .0 here]
</code></pre>
<p>the first bit just divides 600851475143 by every number between 300 and 1 in turn. I then need to filter this list to get only the ones that are whole numbers. I have a filter in place, but where the comment is i need a rule that will tell if the particular value in the list has .0</p>
<p>Any way this can be achieved?</p>

<li><p>Well I tested this code on simulator(on SDK 3.0/3.2) with opening another app(tried http instead of tel protocol). The check executes in background while other native app(safari) run in foreground.</p></li>
<li><p>So this look a little odd behavior what apple guys says.</p></li>
<li><p>So can any one help me to find whether i can use this code in my work. and will it be acceptable by Apple store.</p></li>
</ul>
<p>Thanks in advance.</p>

<pre><code>while(drr.Read())

LinkButton lb = new LinkButton();
lb.Click += new EventHandler(lb_Click);
lb.Text = drr[2].ToString();

Java split before and stop
|
<p>I have a JTextField and I'm using it to put info into a JTextArea. I want a command that puts text into it, but I'm having to use split to check if it's the /text command. When I do "/text Message To Put", it cuts off at the spaces. How can I get the "Message to put" as a whole to output to the JTextArea?</p>

JQUERY common function library create script errors. How to avoid?
|
<p>I am building a common function library but the functions inside need to reference different jquery files, which they may need to be referenced in some pages but not in others.</p>
<p>When I called this common function library in one web page which is only going to use one function, and I don't reference the files need it for the other function, then it will create a script error.</p>
<p>My question is if it would be possible to stop this script errors like...</p>
<pre><code>//This if statement is what I was thinking to stop going through
if ($(".objectdate") != null){
//This is the function that is calling other jquery files and creates error.
$(document).ready(function() {
$(".objectdate").datepicker({
//Code inside.
});
});
}
</code></pre>
<p>Thanks. </p>

jquery disables all the checkbox in a table
|
<p>How can I disable only a single check box in a table row? I have my for condition in a phtml file. My html has one <code>td</code> for my checkbox, but if I click on one check box it disables all the checkboxes in a table. Below is my for loop with check box.</p>
<pre><code><?php
foreach($this->rows as $record)
{
echo "<tr>";
echo "<td >". $record['firstname'] . "</td>";
echo "<td>".$record['advicetoowners'] . "</td>";
echo"<td>".$record['customdata'] . " <br /> ".$record['reservation'."</td>";
?>
<td class='stylecontent'width='2' >
<input type="checkbox" name="seen" value="" class='chkAll'/>
</td>
<?php
}
?>
</code></pre>
<p>My jQuery is:</p>
<pre><code>$('.chkAll').change(function() {
// This disables all the check box in a table.How to make it to disable only one
$('input:checkbox').attr('disabled', this.checked);
});
</code></pre>
