652,993 | 652,994 | jQuery variable and object caching | <p>This is something that has been bugging me some time and every time I found myself using different solution for this.</p>
<p>So, I have link in my document which on click creates new element with some ID.</p>
<pre><code><a href="#" id="test-link">Link</a>
</code></pre>
<p>For the purpose of easier reusing, I would like to store that new elements ID in a variable which is jQuery object</p>
<pre><code>var test = $('#test');
</code></pre>
<p>On click I append that new element on body, new element is DIV</p>
<pre><code>$('body').append('<div id="test"/>');
</code></pre>
<p>And here goes the main "problem" - if I test this new elements length with <em>test.length</em> it first returns 0 and later 1. But, when I test it with <em>$('#test').length</em> it returns 1 from the start.</p>
<p>I suppose it is some caching mechanism and I was wondering is there better, all-around solution which will allow to store elements in variables in the start for later repurpose and in the same time work with dynamically created elements.</p>
<p>Live, delegate, something else? What I do sometimes is create string and add it to jQuery object but I think this is just avoiding the real issue. Also, using .find() inside another jQuery object.</p>
<p>Thanks in advance.</p>

The syntax for the existing variables is similar to <code>%(order.random_variable)s</code> or <code>%(item.random_variable)s</code> This looks similar to the string placeholder <code>%s</code> in Python and I'm fairly confident that it is related, if not the same, but I don't quite understand the syntax.

3,374,839 | 3,374,840 | android location listener question | <p>I am developing an location aware application that needs to know the users location.
The problem is that the application doesn't seem to work properly.</p>
<p>By properly I mean that every time I have to first open an application (like cardio trainer) in order to get a GPS signal and then run my program, otherwise the GPS icon on the notification bar is blinking like it blinks when the device tries to get GPS signal and after a while it stops and no location is returned!</p>
<p>this is really weird because it shouldent stop, is there an interval that android provides the gps to get signal?</p>
<p>on the documentation I haven't found anything about that.</p>
<p>my code is as follows:</p>
<pre><code>lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 60000, 10, locationListenerGps);
LocationListener locationListenerGps = new LocationListener() {
public void onLocationChanged(Location location) {
locationResult.gotLocation(location);
Log.e("##################","MyLocation got GPS location accuracy:
"+location.getAccuracy()+" Altitute: "+location.getAltitude()+" log:
"+location.getLongitude()+" lat: "+location.getLatitude());
}
public void onProviderDisabled(String provider) {}
public void onProviderEnabled(String provider) {}
public void onStatusChanged(String provider, int status, Bundle extras) {}
};
</code></pre>
<p>That should open the gps provider and register a listener called locationListenerGps that would be called by the location manager every 1 minute or 10 meters right?</p>
<p>why I have to open cardioTrainer first to get a GPS signal?</p>

I implemented the timeout approach from @commonsware and it worked fine, but my users are not happy with it. They want to prompt for PIN everytime when the app is coming from background.</p>
<p>Now I am implemeting the solution from @hackbod by having every activity increment the counter in onStart and decrement the count in onStop.
<a href="http://stackoverflow.com/questions/5836843/android-detecting-if-an-application-entered-the-background">Android detecting if an application entered the background</a></p>
<p>But the problem is when users changes the Orientation of the current activity the counter sets back to 0 and my app thinks the user is coming from background.
my onStart() increments the counter and onStop is decrementing the counter.
I want android to take care of the orientation change as I have different layouts for different orientation.</p>
<p>I don't want to use GET_TASKS approach for now.

4,766,785 | 4,766,786 | Best way of returning a pointer | <p>I have seen at least 5 C++ tutorial sites that return pointers this way:</p>
<pre><code>int* somefunction(){
int x = 5;
int *result = &x;
return result;
}
</code></pre>
<p>Is that not a very, VERY bad idea? My logic tells me that the returned pointer's value can be overwritten at any time. I would rather think that this would be the right solution:</p>
<pre><code>int* somefuntion(){
int x = 5;
int* result = new int;
*(result) = x;
return result;
}
</code></pre>
<p>And then leave the calling function to delete the pointer. Or am i wrong?</p>

3,786,481 | 3,786,482 | javascript solution to display relavant ads (sth like AdSense) | <p>I would like to place relevant ads on the product pages of an ecommerce site. I know that usually such ads are stored in a database table that links the given product and the ads. But now I wonder if it's possible to code a similar system with javascript. I mean something like a script that is loaded with the page and it parses the given page's content, looks for keywords (relevant words) and uses these keywords to query a database for ads to display. It'd be something like Google AdSense... but I am not sure how that works. Do you think it's possible to develop such a system? Anybody here who ever tried to code it?

4,192,932 | 4,192,933 | The Obsever pattern (or something similar) using a global update() function in C++? | <p>I am creating an MVC application in C++ and I want the lower level model classes to be able to update the GUI with simple text to display output to the reader. I don't want to have to pass around function or object pointers as it would get messy and I would have to pass them around all over the place. What I essentially want is the equivalent to 'cout' for a console GUI - some sort of global function that can be called to update the GUI from anywhere without having to know anything about the GUI.</p>
<p>I've mentioned the Observer pattern in the title because it sounds a lot like that - the GUI could subscribe to this global object or function in someway and listen for when it is called. However, I'm not specifically looking for a solution using Observer.</p>
<p>People have mentioned signals and slots to me but surely, unless global, you are still required to 'pass things around' to allow objects to emit the signals. Again, a global point of reference would be helpful.</p>
<p>How can I do this while ensuring that good design principles are adhered to?</p>

<p>I am not looking for extremely complex checking, just something to stop the user before the submitting an update to the database. For example, I have a calendar where the user needs to select a date. If they fail to select a date, I would like to not process the update and instead return a warning like "Are you nuts, enter a date!"</p>

<p>Maybe someone else will find this fascinating <em>and</em> have an answer. If you run this, it outputs <code>I think the var is a</code> when <em>clearly</em> it's <code>0</code>. Now, I'm most certain this has something to do with the fact that we're using strings in our <code>switch</code> statement but the variable we're checking is an integer. Does anyone know why PHP behaves this way? It's nothing too major, but it did give me a bit of a headache today.</p>

<p>App will have set of activities and one background service so when app starts,at that time service will start and TTS engine will get initialize with default language as English in service(onInit() method). I have to set the language which will be set by the user when that particular activity starts.</p>
<p>So how to configure the selected language locale in TTS engine at runtime? </p>
<p>My observation is when service starts at that time only TTS engine get intialize with the default language inside onInit() method and at instance activity is not available so we will not have any configured language details so we can't do that but actual problem what I am facing is second time onwards how to change the locale of TTS engine(When user selects language from the activity) because we can't use mTts.setLanguage(Locale.FRENCH) outside of onInit() method as if you call this also it will not reflect changes in TTS.</p>

I'm on day 2.I love how clean it is, and the libraries, etc. I'm not a big fan of the indention yet, but wanted to get some feedback on ways people deal with this. A big issue for me right now is refactoring and then the consequent re-idention that needs to happen for nested calls. This seems like a real pain. What are the ways people suggest to get around this? Any good ideas, or editors that would make this easier? I'm using ultrastudio and it doesn't seem to handle this very well.</p>
<p>example</p>
<pre><code>if os.stat(filepath)[0]:

<pre><code>if root in thingsIwant:
if os.stat(filepath)[0]:
do something special

<p>Is there a better way? It seems that if you need to add a control statement at the top of a nested block this could be a major pain.</p>

If 1 or 2 are selected, x_amount is poulated with 25 or 45. If 3 or 4 are selected, the user enters a value into payment_mount and then x_amount becomes payment_amount x 1.03. I want, if a user selects 1 or 2, then both payment_amount and x_amount are populated with 25 or 45. Here is the JS that is working to populate x_amount with a static number:</p>
<pre><code>function SI_money(amount) {
// makes sure that there is a 0 in the ones column when appropriate
// and rounds for to account for poor Netscape behaviors
amount=(Math.round(amount*100))/100;
return (amount==Math.floor(amount))?amount+'.00':((amount*10==Math.floor(amount*10))?amount+'0':amount);
}
function calcTotal(){
var total = document.getElementById('x_amount');
var amount = document.getElementById('payment_amount');
var payment = document.getElementById('x_ship_to_address');
if( payment.selectedIndex == 0)
total.value = 'select Type of Payment from dropdown';
else if( payment.selectedIndex == 3 || payment.selectedIndex == 4 )
total.value = SI_money(parseFloat(amount.value * 1.03));
else if( payment.selectedIndex == 1 )
total.value && amount.value = SI_money(25.00);
else if( payment.selectedIndex == 2 )
total.value = SI_money(45.00);
}
</code></pre>
<p>I think I want the last two ifs of calcTotal to be something like:</p>

total.value && amount.value = SI_money(25.00);
else if( payment.selectedIndex == 2 )
total.value && amount.value = SI_money(45.00);
