<p>How can I insert an animated gif image in Java?</p>
<p>I have already looked at different answers and question. But when I code this, it doesn't show the gif animated.</p>
<pre><code>Image image = Toolkit.getDefaultToolkit().getImage("yourFile.gif");
Image image=ImageIO.read(new File("yourFile.gif"));
</code></pre>
<p>In the end, I use the method <code>drawImage</code>.</p>

repeating function with time
|
<p>I am trying to display sports scores every 90 seconds in an iframe. I have everything working except for one part. The issue I have is that once the time goes from 90 to 0 it loads the html page into and iframe and continues to reload the same html page forever. How can I make it load one time, and then start the 90 second countdown over again?</p>
<pre><code>// variables
var timeCountdown = 90,
minutesCountdown,
secondsCountdown,
mainCountdown;
// main script countdown
mainCountdown = setInterval(function() {
// display countdown time
document.getElementById("countdown").innerText = mainCountdown + " seconds remaining!";
// if time is 0 or smaller
if (timeCountdown <= 0) {
// load sports scores
document.getElementById("iframe").src = "sports/nba/feed.html";
} else {
// convert random time to minutes
minutesCountdown= Math.floor(timeCountdown / 60);
// convert random time to seconds
secondsCountdown = (timeCountdown % 60);
// add leading zero to seconds if less than ten
if (secondsCountdown < 10) {
secondsCountdown = "0" + secondsCountdown;
}
// add leading zero to minutes if less than ten
if (minutesCountdown <= 10) {
minutesCountdown = "0" + minutesCountdown;
}
// display countdown until next search
document.getElementById("countdown").innerHTML = "Loading NBA scores in " + minutesCountdown + ':' + secondsCountdown;
// reduce countdown time
timeCountdown--;
}
}, 1000);

how to test thread safety of a module?
|
<p>I want to use a module to help serve pages in cherryPy. The module works great in a single thread, and it does not use inter-thread communications (queues, ...). Still, there is a slight possibility that some side effects (e.g. via global) may occur in a multi-threaded environment such as CherryPy.</p>
<p>What test strategy or test program can I use to verify the thread safety of the python module / function ? Is there anything better than monkey testing ? Are there any thread-safety testing framework for python ?</p>
<p>(I've seen the responses for similar questions in other languages)</p>

spliting an array without foreach

<p>So I have an array of items</p>
<pre><code> $arr1 = Array(266=>"foo",178=>"bar",3="foobar");
</code></pre>
<p>and then I have an of array of numbers like this</p>
<pre><code> $arr2 = Array(0 => 266, 1 => 178);
</code></pre>
<p>and so what I want to do is split array one into two arrays </p>
<p>where the values of $arr2 that match the index of $arr1 are moved to a new array so I am left with</p>
<pre><code> $arr1 = Array(3="foobar");
$arr2= Array(266=>"foo",178=>"bar");
</code></pre>
<p>that said I know I could do this with a foreach loop but I wonder if this is a simpler and faster way to do this </p>
<p>something like array_diff would be could but I don't think that will work</p>

Where did java get the idea for Interfaces from?

<p>I'm aware that most things in modern programming languages are at least <strong>partially</strong> based on features in earlier languages.</p>
<p>This leads me to wonder where java got the inspiration for interfaces from. Was it mostly their own creation? Was it based on fully Abstract Base classes(with multiple inheritance) ?</p>

jQuery Hide and Show DOM Element
|
<p>I have the following code:</p>
<pre><code>jQuery(document).ready(function ($) {
var objModal = '<div id="Modal"><div class="ModalContent"><p>please wait</p></div></div>';
function JS_Utils_ShowModal() {
if (!objModal) {
$('body').append(objModal);
}
}
function JS_Utils_HideModal() {
if (objModal) {
$('body').remove(objModal);
}
}
// Forces the modal to show full height in IE6
if ($.browser.msie && $.browser.version == "6.0") {
$('div#Modal')
{
var overlayHeight = $('body').height();
$('div#Modal').css({ 'height': overlayHeight });
}
}
</code></pre>
<p>});</p>
<p>The basic idea is that when the page loads it builds a modal box, and hides it! When a user makes the JS_Utils_ShowModal function run it will then show the modal. However this doesn't seem to work, any ideas why? And is window.onload the best way to build the modal when the page loads up?</p>
<p><strong>EDIT: Changed it so that the modal is a variable that I would like to append and remove from the DOM when user runs one of the functions. I also need to check that the modal doesn't already exist before adding it or removing it!</strong></p>
<p>Thanks.</p>

Determining time elapsed between 2 dates

<p>I am trying to determine the time elapsed between 2 dates using javascript. An example would be: "I quit smoking on January 5, 2008 at 3 A.M., how many years, months, and hours has elapsed since I quit?".</p>
<p>So my thoughts were:</p>
<ol>
<li>Get "quit" date</li>
<li>Get current date</li>
<li>Convert to time (milliseconds)</li>
<li>Find the difference</li>
<li>Create a new date using the difference</li>
<li>Extract the years, months, etc. from that date</li>
</ol>
<p>Well, it is acting strange and I can't pin point why. Any insight?</p>
<pre><code>//create custom test date
var d1 = new Date(2012, 8, 28, 13, 14, 0, 0);
//create current date
var d2 = new Date();
//get date times (ms)
var d1Time = (d1.getTime());
var d2Time = (d2.getTime());
//calculate the difference in date times
var diff = d2 - d1;
//create a new date using the time differences (starts at Jan 1, 1970)
var dDiff = new Date();
dDiff.setTime(diff);
//chop off 1970 and get year, month, day, and hour
var years = dDiff.getFullYear() - 1970;
var months = dDiff.getMonth();
var days = dDiff.getDate();
var hours = dDiff.getHours();

jQuery > reset popup window 's x and y relative to icon that launched the window
|
<p>I have a jQuery jPicker colorpicker that is bound to an input text field and opens onclick of a small picker.gif icon. The problem I'm having is that (1) The colorpicker that opens does not appear to be positioned according to the x/y position of the picker.gif (it opens far away from the click point) and (2) The colorpicker does not seem to be aware of the viewport's scroll position (the top of the colorpicker is partially hidden at the top of the window).</p>
<p>I'd like to use jQuery to reposition the colorpalette (1) Based on the x/y position of the input that its bound to and (2) reset it's top position based on the viewport's visible Y position.</p>
<p>Here is the script where I am creating a new jPicker and binding it to my input text fields for header and sidebar...</p>
<pre><code>$('#theme_header_color').jPicker
(
{position: { x: $(this).offset.left + $(this).width(), y: ($(this).offset.top - $(window).scrollTop()) + $(this).height() }},

Collection of template-heterogeneous types
|
<p>I have a bunch of <code>boost::property_map</code>s defining costs of edge traversal in a graph. I'm executing an algorithm with differently weighted combinations of these maps, currently by manually doing <code>totalcost = weight1*weight1_factor + weight2*weight2_factor + ...</code>. The number of property maps is rising though, and it's becoming a hassle to sum them up like this.</p>
<p>So, I envisioned creating an aggregation class, which contains a collection of some sort of all the maps. However, they are templated differently, as <code>boost::property_map<Graph, PropertyTag></code>, where the <code>PropertyTag</code> differs among the maps. Since they all support <code>operator[](edge_escriptor)</code>, is there some trick I can use, or am I doomed to use <code>boost::any</code>?</p>

Android ant build: how to run android upload and not update build.xml, proguard.cfg
|
<p>0 down vote favorite</p>
<p>I am running the standard ant script 'build.xml' which gets created when you run the 'android create project' command. In order to verify my local.properties is set correctly, I added a task at the beginning of the build.xml script to run the command:
android update project -p .</p>
<p>I now get this message each time I run the ant script:
'File build.xml is too old and needs to be updated', </p>
<p>which clobbers my build.xml file and creates a proguard.cfg file.!!!</p>
<p>So, I moved the ant script to a different file that won't get clobbered.</p>
<p>Is there a way to run the command 'android update project -p .' that doesn't clobber build.xml and create proguard.cfg?</p>

I finally feel like I am getting close but now the crash is crashing sporadically - I assume it is some sort of memory issue but have no clue how to fix it. If I reset the settings of the iphone simulator and then run the app it works great for quite a while. Then if i close the simulator and re-run the app, it will crash when this method is called:</p>
<pre><code>-(IBAction)selectedProfile {
NSInteger rowSelected = [profilePicker selectedRowInComponent:0];
NSUserDefaults *profiles = [NSUserDefaults standardUserDefaults];
if(rowSelected == 0) {
[profiles setInteger:1 forKey:@"activeuser"];
} else if (rowSelected == 1) {
[profiles setInteger:2 forKey:@"activeuser"];
} else if (rowSelected == 2) {
[profiles setInteger:3 forKey:@"activeuser"];
}
[profiles synchronize];
FormsViewController *rootVC = [[FormsViewController alloc] init];
UINavigationController *theNavController = [[UINavigationController alloc]
initWithRootViewController:rootVC];
theNavController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:theNavController animated:YES];
[rootVC release];
[theNavController release];
</code></pre>
<p>}</p>
<p>I am wondering if it has to do with the way I am dealing with the persistent data because I didn't have this problem prior to implementing it. The user is given a UIPickerView with 3 options and the rest of the app is dependent on which of those 3 options the user chooses. Could it be the persistent data?</p>

When will one need to create a separate process in a Application?
|
<p>I was reading a article in Android developer blog <a href="http://developer.android.com/guide/topics/fundamentals/processes-and-threads.html" rel="nofollow">Process and Threads</a> which talks about creating new process for specific component of Application. But I failed to understand when will creating a new process in my application becomes a absolute need. Could you please help me understand following doubts I have in this regard.</p>
<ol>
<li>When as a developer I should feel I need to have a separate process for a Android component/s?</li>
<li>Does introducing a new process has any side effect on application's overall performance?</li>
</ol>
<p>Any other info is greatly appreciated.</p>
<p>Thanks,

How android OS version compatibility works?
|
<p>If I use the following code in my app together with Android 2.1 library my app won't compile because GINGERBREAD variable is not visible.</p>
<pre><code>public static boolean SUPPORTS_GINGERBREAD = android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.GINGERBREAD;
</code></pre>
<p>On the other hand if use 2.3 library instead of 2.1 my app is compiled and successfuly run on 2.1 device.</p>
<p>Why is there no exception if I launch 2.3 compiled build on 2.1 device?</p>
<p>For example if I run the same program on 1.5 device there is a crash because Android can not find SDK_INT constant which was introduced only in 1.6. Note that there is no such crash for GINGERBREAD constant which was introduced in Android 2.3</p>
<p>Thanks!</p>

What is the proper way to acces a property from an object inside several scopes of a method?
|
<p>For example, if I have the object:</p>
<pre><code>function Website(){
this.images = [];
}
Website.prototype.getImages = function(){
jQuery('img').each(function(key, val){
this.images.push(val.src);
})
}
</code></pre>
<p>and I try to call <code>website.getImages()</code> I get this error: <code>TypeError: Cannot call method 'push' of undefined</code></p>
<p>So, in order to fix this, I would do:</p>
<pre><code>Website.prototype.getImages = function(){
var images = this.images;
jQuery('img').each(function(key, val){
images.push(val.src);
})
}
</code></pre>
<p>But I don't see this solution as clean, because what if im trying to access several variables.</p>
<p>Is there a cleaner and better way to do this?</p>

Enumerate Java Fields
|
<p>I have a Java class with ~90 fields. I want to be able to do things to every field (generate an XML element for instance) without writing the same 5 lines of code with slight substitutions 90 times. In Objective C I think you can get to instance variables in ways similar to accessing Dictionary elements (ObjectForKey). Is there anything similar in Java such that I can get an array of the fields then do something to each of them?</p>

Private Inheritance and Derived Object to Base reference
|
<p>As far as I understand the reason that we cannot pass a derived class object to a base class reference for private inheritance is that Since Derived is privately inherited from Base, the default constructor of Base would be called before the constructor of Derived. But because it is private and not inherited to Derived, we get a compiler error.</p>
<p>But, if I try to create a public constructor for Base and inherit from Derived privately and then re-assign the public status to Base's constructor will it allow me to pass a derived's instance to Base reference?</p>
<p>I tried it as follows,</p>
<pre><code>#include <iostream>
using namespace std;
class base
{
public:
base(){}
void print(){ puts("In base"); }
};
class derived : private base
{
public:
base::base; /* Throws an error - Declaration doesnt declare anything*/
void print(){ puts("In derived"); }
};
void func(base& bRef)
{
}
int main()
{
derived dObj;
func(dObj); /* Throws an error - 'base' is an inaccessible base of derived */
}
</code></pre>
<p>It throws an error for base::base (publicizing privately inherited constructor to public).
Is what I am trying valid? Can anyone please tell me?</p>

Running the Android example SampleSyncAdapter

<p>I installed the example SampleSyncAdapter from the sdk into eclipse--it runs in the emulator--e.g, if i go to Settings>>Account & Sync, I do see the SamplesyncAdapter Account--but i can't log in when i select it--the Google documentation is next to useless in terms of orienting developers--what should I enter to log in? How do I run the application--I want to run it in debug to walk thru the code.</p>
<p>UPDATE: i found answer--if anyone is having same issue:</p>
<p><a href="http://groups.google.com/group/android-developers/browse_thread/thread/ac875a97679122f0" rel="nofollow">http://groups.google.com/group/android-developers/browse_thread/thread/ac875a97679122f0</a></p>
<p>Refer to the reply by Megha in the above thread--also, refer to the class NetworkUtilities if you are trying to understand how the external server is contacted for the update--in my case I will alter this class to point to a local tomcat/servlet to experiment.</p>
<p>It sure is hard to understand why the Google Developer Reference site does not contain the information in the above thread--which was supplied by a google employee over a year ago.</p>

jQuery copy multiple date dropdowns to hidden field

Static methods vs instance methods in BLL
|
<p>Was asked today why I used code like this for my bll classes in an asp.net app:</p>
<pre><code>public class StudentBll
{
public static DataTable GetStudents()
{
return DBHelper.ExecuteSp("GetStudents");
}
public static DataTable GetStudentById(int studentId)
{
return DBHelper.ExecuteSp("GetStudentById", studentId);
}
}
</code></pre>
<p>instead of</p>
<pre><code>public class StudentBll
{
public DataTable GetStudents()
{
return DBHelper.ExecuteSp("GetStudents");
}
public DataTable GetStudentById(int studentId)
{
return DBHelper.ExecuteSp("GetStudentById", studentId);
}
}
</code></pre>
<p>Only thing I could think of was that</p>
<p>A) <strong>Performance</strong> A slight increase (not sure of the specifics)</p>
<p>B) <strong>Readability</strong>
<code>StudentBll.GetStudents();</code> rather than </p>
<pre><code>StudentBll studentBll = new StudentBll();
studentBll.GetStudents();
</code></pre>
<p>I wasn't too confident in those answers, however. Anyone care to enlighten me?</p>

Can't read SharedPreferences fron another application
|
<p><strong>EDITED:</strong></p>
<p>I have one app that writes to SharedPreferences like that:</p>
<pre><code> Context otherAppsContext = null;
try {
otherAppsContext = createPackageContext("AfroKeyboard.com.rob", Context.CONTEXT_IGNORE_SECURITY);
} catch (NameNotFoundException e) {
}
SharedPreferences sharedPreferences = otherAppsContext.getSharedPreferences("PREFS_PRIVATE", Context.MODE_WORLD_READABLE);
Editor prefsPrivateEditor = sharedPreferences.edit();
prefsPrivateEditor.putString("layout02", jString);
prefsPrivateEditor.putString("layout02name", "Russian Layout");
prefsPrivateEditor.commit();
</code></pre>
<p>and another app that has to read from them</p>
<pre><code> Context otherAppsContext = null;
try {
otherAppsContext = createPackageContext("AfroKeyboard.com.rob", Context.CONTEXT_IGNORE_SECURITY);
} catch (NameNotFoundException e) {
}
SharedPreferences sharedPreferences = otherAppsContext.getSharedPreferences("PREFS_PRIVATE", Context.MODE_WORLD_READABLE);
Log.e( "name2" , "name2: "+sharedPreferences.getString("layout02name", "") );
</code></pre>
<p>but it returns empty.</p>
<p>What do you think might be the problem?</p>

c++ - Is there a way to auto-cast values when assigning them to references`?
|
<p>I'm wondering if there is some way that C++ autocasts values that I want to assign to a reference.</p>
<pre><code>class X{
public:
X(int x){
}
};
int main(){
X x = 5; //works
X& y = 6; //doesn't work
X& z = (X)7; //works
return 0;
}
</code></pre>
<p>As you can see, assigning 6 to the reference y does not work without casting it before. Is there something I can add in the definition of the class X to make this work without the casting, so that the non-working line would work?</p>
<p>Basically I want to achieve that, for example a function like this:</p>
<pre><code>void doSomething(X& x){
//...
}
</code></pre>
<p>Could be called like this after that:</p>
<pre><code>doSomething(7);
</code></pre>
<p>Is it possible?</p>

javascript code architecture question
|
<p>I'm about to make a web app which will have a pretty heavy client end. I'm not sure about the way to organize my javascript code, but here is a basic idea :</p>
<pre><code>// the namespace for the application
var app = {};
// ajax middle layer
app.products = {
add : function(){
// send ajax request
// if response is successful
// do some ui manipulation
app.ui.products.add( json.data );
},
remove : function(){},
...
};
app.categories = {
add : function(){},
....
};
// the ui interface which will be called based on ajax responses
app.ui = {};
app.ui.products = {
add : function( product_obj ){
$('#products').append( "<div id='"+product_obj.id+"'>"+product_obj.title+"</div>" );
}
};
app.ui.categories = {};
</code></pre>
<p>Anybody got similar experiences to tell me the pros and cons of this approach? What's your way of designing client side javascript code architecture? Thanks. </p>
<p>[update] : This web app, as you see from the above, deals with products CRUD, categories CRUD only in a ajax fashion. I'm only showing an snippet here, so you guys know what I'm trying to achieve and what my question is. Again, I'm asking for inputs for my approach to organize the code of this app. </p>

Trying to make a thai translator in Python, but am unable to write using Thai characters

I saw somewhere to do this to check what the default encoding is:</p>
<pre><code>import sys; print(sys.getdefaultencoding())

<p>I get utf-8 </p>
<p>My problem is that I just get ?? when I use Thai characters. Is there a way that I can use them? A different question I am trying to translate a sentence and was wondering how to put a space in between words. As of right now I just get all the words combined in the .txt file. </p>

s[entry]=define
text_file = open("THAI.txt", "w+")
num = int(input("How many words are in sentence"))

if trys in s:

Failed Binder Transaction between activities but not between service and activity?

For some reason, it doesn't have any problem passing along some couple thousand parcelables in an array list along to the app, but when it comes to passing along that data within that app to a new activity that's being launched, I get a "FAILED BINDER TRANSACTION!" error.</p>
<p>Any idea why there's an arbitrary different limit between the two?</p>

Make javascript mandatory in web application?
|
<p>I am building a web application that will have a fair bit of forms. The html forms are generated using php.</p>
<p>One of the things I came across is this:</p>
<p>I have a drop down box for the user to select his country. Once he selects the country, a call is made to the server to fetch a list of states within that country and populate it in a drop down box.</p>
<p>Initially, I thought I could provide 2 options:</p>
<ul>
<li>An enhanced jquery version where ajax is used to fetch the states and the populate it in a drop down.</li>
<li>Where javascript is not availiable, the whole page is submitted to the server and then rerendered with the new states in the drop down.</li>
</ul>
<p>However, onChange() requires javascript. So if someone where to visit the form without javascript enabled, there's no way we can deal with the second option, since javascript is required to submit a form using onChange(). </p>
<p>What are some ways to deal with this? My only solution at the moment is to just make javascript mandatory. Users without javascript enabled will see a message saying that the page will not work properly.</p>
<p>Some sites:</p>
<ul>
<li>Hotmail.com - Refuses to show anything except a "javascript is required message"</li>
<li>Facebook.com - Tells us we should use the mobile version of the site.</li>
<li>Google Maps - Does not work. No message to say javascript is required.</li>
<li>Gmail - Falls back to basic html.</li>
<li>Google account - Does not work. No message to say javascript is required.</li>
</ul>
<p>Is it acceptable to require users to have javascript enabled at the current state of the web (august 2011)?</p>
<p>Just came across this possible solution:
<a href="http://cita.disability.uiuc.edu/html-best-practices/auto/onchange.php" rel="nofollow">http://cita.disability.uiuc.edu/html-best-practices/auto/onchange.php</a></p>
<p>I could perhaps add a button which the user can use to select their country. This should allow us to reload and render the form with the states drop down without any javascript.</p>

Curious: Why is the "throws <SomeSpecific>Exception" syntax required in Java alone?
|
<p>We all know it is needed.</p>
<p>But WHY is it needed in Java alone, when other similar languages that have exception handling capablities don't require us to write "throws Exception"? Is there anyone who knows what was happening when Java language was designed and why they made it that way? Just curious.</p>
<p>P.S. This may not be a practical or really necessary question - it might not help me in anyway with my ongoing projects. But certain language features kindle my curiosity :D</p>
<p><strong>Edit</strong>
Looks like my question was very vague! I think I worded the question wrongly. We need to use the "throws Exception" kind of syntax at some points during programming when dealing with Java code. But something like that is never needed in C# or C++ or even VB.Net and PHP. So why Java alone insists on this?</p>

Attribute mapping with a Python property
|
<p>Is there a way to make a Python <code>@property</code> act as a setter and getter all at once?</p>
<p>I feel like I've seen this somewhere before but can't remember and can't recreate the solution myself.</p>
<p>For example, instead of:</p>
<pre><code>class A(object):
def __init__(self, b): self.b = b
def get_c(self): return self.b.c
def set_c(self, value): self.b.c = value
c = property(get_c, set_c)
</code></pre>
<p>we could somehow signal that for <code>A</code> objects, the <code>c</code> attribute is really equivalent to <code>b.c</code> for getter, setter (and deleter if we like).</p>
<h2>Motivation:</h2>
<p>This would be particularly useful when we need <code>A</code> to be a proxy wrapper around <code>B</code> objects (of which <code>b</code> is an instance) but share only the data attributes and no methods. Properties such as these would allow the <code>A</code> and <code>B</code> objects' data to stay completely in sync while both are used by the same code.</p>

Concat performance
|
<p>I was reading a <a href="http://blogs.msdn.com/b/wesdyer/archive/2007/03/23/all-about-iterators.aspx?PageIndex=2#comments" rel="nofollow">blog post</a> on msdn about iterators which talks about about how <code>Concat</code> has <code>O(m^2)</code> performance where <code>m</code> is the length of the first <code>IEnumerable</code>. One of the comments, by richard_deeming on the second page, provides some sample code which he says is much faster. I don't really understand why it's faster and was hoping someone could explain it to me.</p>
<p>Thanks.</p>
