How to comunicate two androids devices
|
<p>I'm developing an online pong game in which two players could play between them.</p>
<p>I though that for it, players will have to conect to a server and it will tell the players who is online to play. Also the server will save rankings and other stuff.</p>
<p>But for the play, at first I though to use the server for the match too (sending coordinates, etc), but I think that is not the best design because it is really slow.</p>
<p>So I'm thinking that android devices have to can comunicate between them, isn't it? Any idea? They have an ID...</p>
<p>If they can... the server could send the ID of the opponent and with that, the match will start comunicating the stuff between the mobile devices and not with the server.</p>
<p>Need some help pls!</p>

Basic variable manipulation of data-* attributes
|
<p>Imagine the user gets a better discount the higher the data-hipsterness value is and we get this value by asking 4 questions and providing 4 choices for each question. I'm sure it's most basic stuff yet...I need to keep track of a variable every time the user choose one of the options and update it's value so that at the end of the "test" I can do different ifs statements with that result.<br>
What I got so far is a demo <a href="http://lab.polmoneys.com/nohints.html" rel="nofollow">http://lab.polmoneys.com/nohints.html</a> and this code :</p>
<p><strong>EDIT <a href="http://jsfiddle.net/polmoneys/s4xLF/4/" rel="nofollow">http://jsfiddle.net/polmoneys/s4xLF/4/</a></strong></p>
<pre><code>$('h3').click(function(event) {
var value = $(this).data("hipsterness");
var context =$(this).parent(".cpu");
var counter =$("#counter").text();
var newValue= counter + value;
$("#counter").text("" + value);
$("#total").val(newValue);
context.fadeOut("slow", function(e){
context.next(".cpu").fadeIn();
});
});

saving activity state on close of the app by back key press
|
<p>I am creating an App. It has 4 count-down timers.
My problem is,
In the middle of the count-down timer running user may press the back key and close the App. <strong>I want to let the countdown-timer run it's count so that the user can see the updated version of it when he opens the App on next time.</strong>
I thought to manage the state using onSaveInstanceState Callback but I read in the document that it been not called on the event of back key press of the activity. And I tried to check...yes it is not. Is any chance I can solve this using services?</p>
<p>Can someone shed some light on this please. </p>
<p>Note: I am using Handler.postDelayed for running count-down timers. </p>

Record method calls including parameters such that they can be executed after program has executed
|
<p>I am creating an automated test framework. At present in order to best find any issues I have introduced randomness into the tests, such that a test will generate random data and try multiple paths. However this has lead to a problem, I am no longer able to easily re-execute failed tests.</p>
<p>In order to proceed I need to implement a way to store the actions of the test, including their parameters. With the way I have implemented the framework all of the "work" is handled by one class, thus if I was able to record the methods invoked with parameters in this class then I would have a full record of actions executed in the script.</p>
<p>From this list of methods though I need an easy way to re-execute these method calls, preferably with as little manual work as possible.</p>
<p>Sorry if this has been asked before but I wasn't able to find anything to help.</p>

Is it bad to have large objects on the heap?
|
<p>what are the consequences (if any) of having big objects stored on the heap rather than in the stack? I remember reading that it was preferable to have the bigger objects on the stack to limit the heap fragmentation... is that true?
thanks</p>
<p>edit : question comes from a game I'm making where my basic object that will have all the informations about textures, entities etc will be most likely created on the heap, I don't really have any idea of its size, we could assume something like 300 MB</p>

What is Bool<true> in C++ - is it from boost?

<p>I am trying to use some sample code and my compiler won't compile this line:</p>
<pre><code>static void exitActions(Host& h, Bool<true>) {}
</code></pre>
<p>Compiler is MS VS2005. I don't recognise Bool - so not sure how to replace it. Is this default parameter equivalent:</p>
<pre><code>static void exitActions(Host& h, bool b = true) {}
</code></pre>
<p>The sample is from <a href="http://accu.org/index.php/journals/252" rel="nofollow">http://accu.org/index.php/journals/252</a>. The code is just snippets in the text - no snippet about what is #include'd - so hard to work out. There is no definition for a Bool template.</p>

<p>I want to resize a image using server side script (eg: <a href="http://shiftingpixel.com/2008/03/03/smart-image-resizer/" rel="nofollow">Smart Image Resizer</a> ), so it will send request to a script called image.php</p>

"::" in php for calling non-static functions works out of class
|
<p>as far as i know, <code>::</code> is using for calling static functions and base class functions in a subclass. and as far as i know, usually we have to create an instance of a class for using it out of the class. </p>
<pre><code>class a
{
public function foo()
{
//
}
}
</code></pre>
<p>for using this class:</p>
<pre><code>$instance = new a();
$instance->foo();
</code></pre>
<p>but its possible that we call the <code>foo</code> function without creating any instance and only using <code>::</code>. for example the following code is written out of class and works well:</p>
<pre><code>a::foo();
</code></pre>
<p>why does it work? and how? </p>

How to implement a "read more" link with jQuery
|
<p>I want to be able to display a shortened version of a long text field by default, but then have a "read more" link that would expand the field to its full version. I have a pretty simple setup right now, but feel like there should be a more efficient way of doing this.</p>
<p>Here's my current code:</p>
<pre><code>$(document).ready(function () {
$("#narrative-full").hide();
$("a#show-narrative").click(function() {
$("#narrative-short").hide();
$("#narrative-full").show('fast');
});
$("a#hide-narrative").click(function() {
$("#narrative-full").hide();
$("#narrative-short").show('fast');
});
});
</code></pre>
<p>This works, but seems clunky. For example, it would be nice to have the original text not flicker or disappear briefly, but instead just smoothly expand. Any suggestions?</p>

Foreach Variable Error
|
<p>I am clearly just missing something with this.
I have the following:</p>
<pre><code> List<string> stringList = new List<string>();
</code></pre>
<p>I then fill it with some data and do the following:</p>
<pre><code> foreach (List<string> results in stringList)
</code></pre>
<p>But it errors claiming that it "cannot convert from type <code>string</code> to type <code>System.Generic.Collections.List<string></code>" ...but both are of type <code>List<string></code> so where is the disconnect? I am sure there must be something very simple I'm clearly doing wrong, but for the life of me I cannot find it.</p>

How can you avoid clock exploits in Android games?
|
<p>I need to measure a period of time that can last up to a few hours. I'm assuming the normal way to do this would be something like:</p>
<pre><code>Date date = new Date();
...wait some time...
(new Date()).getTime() - date.getTime())
</code></pre>
<p>But could a user change Android's clock back an hour to cheat the game and make the timespan shorter? Would reading time from an online source be the best solution?</p>

File operation in Java

<p>I have file reader object in Java.</p>
<p>When we load the file in, is entire file loaded or only file pointer will be loaded like in C. Because I have application (producer) wherein it keeps on writing to the file and other application (consumer) will start to read the file after few minutes, I want to read all file data which will be written by the application producer.</p>

Separate functions in python?
|
<p>I'm not sure if function is the word I am looking for. In fact I don't really know what I'm saying but I have some code and it's not quite doing it what I want to. Basically I want to copy and paste this code I've got and email it to someone. I want them to be able to simply copy and paste it into their Terminal and perform calculations.:</p>
<pre><code>## SCSAC.py
def round(x, base=5):
return int(base * round(float(x)/base))
option = 'yes'
while (option == 'yes'):
x=float(raw_input('How many accumulated orders do you have from retailers: '));
y=float(raw_input('How many units are in the inventory: '));
z=float(raw_input('How many accumulated orders have you placed: '));
print 'Place an order of %s units' % round(((x / 25 + y / 10 + z / 25) + 115));
print ;
option=raw_input("Do you wish to calculate another order? (Enter 'yes' to continue or any other key to quit):: ");
print
</code></pre>
<p>Whenever I type this code in line for line, it works perfectly. That's because there are basically 3 seperate things happening here. </p>
<ol>
<li><p>I define "round" which rounds a value to the nearest 5.</p></li>
<li><p>I define an option to loop the program upon completion</p></li>
<li><p>I define the actual program, and in that I round the answer and conclude with the option to loop. You may notice 2 <code>print</code>'s that don't print anything, but they are only there to have blank lines. </p></li>
</ol>
<p>When I copy and paste it, I get a syntax error.
I am not a programmer and I have just been playing with this all day. I just want to know how I can edit this code so it is copy/paste-able and will run the way it is supposed to. </p>

Weird, the jquery ajax call not working on localhost?
|
<p>I am using Ubuntu 11.10 + apache2. I have a simple ajax call in my html file, and it works fine when I view the page as a file, but when I copy this html file into my apache server under /var/www, the ajax call is not working anymore, the jquery library is loaded correctly, and I can see it via firebug, and the selector works also but not this ajax call (I think all the code within $(document).ready(...); is not working). Any ideas?</p>
<p>Update: The real problem is: there is is a conflict in the javascript library in my code, I have jquery library, and also a library written by js prototype framework, and there is a function from the prototype library but is recognized as a jquery function. please vote to delete this question. Sorry for that.</p>

Should interface/abstract class contains only pure virtual methods?
|
<p>I am a bit weak with designing and I wonder whether it's a good design to have simple virtual methods (not only pure virtual) in an interface? I have a class that is some kind of interface:</p>
<pre><code>class IModel {
void initialize(...);
void render(...);
int getVertexCount() const;
int getAnotherField() const;
};
</code></pre>
<p>the initialize and render methods need to be reimplemented for sure, so they are good candidates for pure virtual methods. However, the two last methods are very simple and practically always with the same implementation (just returning some field). Can I leave them as virtual methods with default implementation or is it better to have it pure virtual that needs to be reimplemented, because it's an interface?</p>

Android onBackPressed/onUserLeaveHint
|
<p>Just a bit of advice needed really. I have an Activity running with my game in it and when the user presses the Back button it will exit back to the Main Menu using the onBackPressed() method, but I am also overriding the onUserLeaveHint() to do the same action if the Home Button is pressed or a phone call is received. However this method is also called when the Back button is pressed, meaning that the Main Menu Intent is called twice with one on top of the other.</p>
<p>If anyone has an idea about how to get around this issue or a better way of handling the two events it would be much appreciated.</p>
<p>Thanks.</p>

Problem with Pointer object in C++
|
<p>I have a very simple class that looks as follows:</p>
<pre><code>class CHeader
{
public:
CHeader();
~CHeader();
void SetCommand( const unsigned char cmd );
void SetFlag( const unsigned char flag );
public:
unsigned char iHeader[32];
};
void CHeader::SetCommand( const unsigned char cmd )
{
iHeader[0] = cmd;
}
void CHeader::SetFlag( const unsigned char flag )
{
iHeader[1] = flag;
}
</code></pre>
<p>Then, I have a method which takes a pointer to CHeader as input and looks
as follows:</p>
<pre><code>void updateHeader(CHeader *Hdr)
{
unsigned char cmd = 'A';
unsigned char flag = 'B';
Hdr->SetCommand(cmd);
Hdr->SetFlag(flag);
...
}
</code></pre>
<p>Basically, this method simply sets some array values to a certain value.</p>
<p>Afterwards, I create then a pointer to an object of class CHeader and pass it to
the updateHeader funtion:</p>
<pre><code>CHeader* hdr = new CHeader();
updateHeader(hdr);
</code></pre>
<p>In doing this, the program crashes as soon as it executes the Hdr->SetCommand(cmd)
line. Anyone sees the problem, any input would be really appreciated </p>

JQuery + Find Checkbox with ; in id

<p>Currently the checkbox ID and Name value have a ; in it see below</p>
<pre><code><input id="K48_h6;547ECE8D417501D623E11F94E0DF94FD" name="K48_1" value="h6;547ECE8D417501D623E11F94E0DF94FD" type="checkbox" style="cursor: pointer;">

<pre><code>$("#K48_h6;547ECE8D417501D623E11F94E0DF94FD").prop("checked",true);
</code></pre>
<p>This is causing me to have a Object doesn't support this property or method.</p>
<p>Since this is a 3rd party product there is nothing I can do with the ;, The Jquery run post the server side code loading.</p>

</code></pre>
<p>The code above throws an exception at line 2 "Input string was not in a correct format."</p>

Adding an image in jpanel inside of a action listener
|
<p>Hello again ladies and gentlemen,
I have once again not been able to figure out something that to you will probably be simple.
I am trying to load 3 images space.jpeg, treefrog.jpeg and yosemite.jpeg (As you click a radio button that the corresponding image is displayed) and have tried adapting every example I can find. If any one wants to point me in the right direction I would greatly appreciate it.</p>
<pre><code>package guiprogramming;
import java.awt.*;
import javax.swing.*;
import javax.swing.border.*;
import java.awt.event.*;
public class ChooseImage extends JPanel {
private JPanel panel1;
private SimplePanel drawingPanel;
JRadioButton button1, button2, button3;
public ChooseImage() {
setLayout(new BorderLayout());
panel1 = new JPanel();
drawingPanel = new SimplePanel();
button1 = new JRadioButton("Scenery");
panel1.add(button1);
button2 = new JRadioButton("Space");
panel1.add(button2);
button3 = new JRadioButton("Tree Frog");
panel1.add(button3);
ButtonGroup group = new ButtonGroup();
group.add(button1);
group.add(button2);
group.add(button2);
this.add(panel1, BorderLayout.NORTH);
this.add(drawingPanel, BorderLayout.CENTER);
button1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//This is where I am trying to get the images to load
}});
button2.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//This is where I am trying to get the images to load
}});
button3.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//This is where I am trying to get the images to load
}});
}
public static void main(String[] args) {
JFrame window = new JFrame("Choose Image");
ChooseImage panel = new ChooseImage();
window.setContentPane(panel);
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setSize(500, 500);
window.setVisible(true);
}
}

Unidentified problem with jQuery's .click() function
|
<p>I'm trying to add an 'onclick' function to an image with jQuery and for some reason it's not sticking. My code looks like:</p>
<pre><code>//create arrow icon/button for li
var img = $('<img></ >').attr('id',i+5)
.attr("src","images/16-arrow-right.png")
.addClass("expImg")
.click(function(){expand(this, 'tdb', 'years', 'danwoods')})
.appendTo(li);
</code></pre>
<p>and the resulting element looks like;</p>
<pre><code><img id="6" src="images/16-arrow-right.png" class="expImg"/>
</code></pre>
<p>It completely leaves out the onclick function, but everything else works fine. Does anyone see a problem with my code, or does the error lie elsewhere? Thanks in advance...</p>

PHP Globals and Reference Difference Confusion
|
<p>Could some one please explain to me what the difference in the following is:</p>
<pre><code>$var = 'something';
function myFunc(){
global $var;
// do something
}
</code></pre>
<p>and (note: the reference sign &)</p>
<pre><code>$var = 'something';
function myFunc(&$var){
// do something
}
</code></pre>
<p>I can't understand the difference between these two methods.</p>
<p><strong>Update</strong> </p>
<p>Hmmm... I think i'm getting alittle confused here :)</p>
<pre><code>$var = 1;
$var2 = 2;
function myFunction(){
global $var, $var2;
$var = $var + $var2;
}
</code></pre>
<p><em>// echo $var would return 3 here.</em></p>
<hr>
<pre><code>$var = 1;
$var2 = 2;
function myFunction(&$a, &$b){
$a = $a + $b;
}
</code></pre>
<p><em>// echo $var would return 3 here aswell.</em></p>
<hr>
<p>I understand those part already, But what i don't understand is the difference between these two approaches, am i wrong to assume that these two approaches are technically the same thing, with different concept of how they are wrote by the coder and also how they are handled by PHP?</p>
<p>If i'm wrong to assume this, then it would really help if you could provide better examples, maybe something that can be accomplished using only one of the above approaches?</p>
<p>ok, i noticed one difference while writing <em>This Update</em>, which is that when doing references i can chose new variable names while keeping the pointer to the variable in the functions scope.</p>

Re-positioning div/ moving div to left and right with JavaScript
|
<p>I am new to javascript and I am trying to start a very simple project which is to display a controllable div that can be moved around using a,w,s,d keys on keyboard. I am currently having problem on how to move around the div because I do not know what attribute to change.</p>
<pre><code>divBar = null;
function detectKey() {
//97 = a
//115 = s
//100 = d
//119 = w
if (event.charCode == 97) {
//a
alert(divBar.position);
}
if (event.charCode == 115) {
//s
}
if (event.charCode == 100) {
//d
}
if (event.charCode == 119) {
//w
}
}
function createDiv() {
divBar = document.createElement("div");
divBar.id = "divBar";
divBar.style.border = "solid 1px #AAAAAA";
divBar.style.backgroundColor = "black";
divBar.style.top = 400;
divBar.style.height = "10px";
divBar.style.width = "100px";
divBar.style.position = "absolute";
document.body.appendChild(divBar);
document.addEventListener("keypress", detectKey, false);
}
</code></pre>
<p>I am not sure to put in that condition statement. so that the div will move to the left, right, up and down.</p>

Unique element ID to reference later
|
<p>I'm trying to figure out a method of storing a unique reference to each tag on a particular page. I won't have any ability to edit the page content and I'll the generated UID to stay the same on every page refresh.</p>
<p>Since browsers don't generate any kind of UID for elements, I was thinking that the only method to do this would be to execute a script which walks the DOM and creates a UID for each it comes across. I don't know how accurate this will be, especially considering I'll need to ensure it creates the same UID for the tag each time the script crawls the page.</p>
<p>Can anyone think of any other, more accurate ways of mapping a page? </p>
<p>Many thanks.</p>

jQuery div opacity management

There are five divs and one has the class of 'on' with page load while the rest have the class 'off'.

<pre><code>.on{opacity:1;}
.off{opacity:0;)
$('li.tunes').click(
function() {
$('div.on').animate({"opacity":"0"},800).removeClass('on').addClass('off', function() {

Referring to the public root in PHP - best practices
|
<p>I've been using the $_SERVER["DOCUMENT_ROOT"] environment variable to refer to the public root in my apps. Now I'm realizing that that's not very reliable. I'm thinking about an approach where I define a constant in my index.php based on a magic constant. Something like that:</p>
<pre><code>define("PUBILC", __DIR__."/");
</code></pre>
<p>I'm not sure about it though.</p>
<p>What approach would you recommend?</p>
