i have menus with sub menus [up to two level Ex: Main menu item--> Sub Menu (A)-->Sub Menu(Sub Menu of menu A)], but the first, second level menu Items are just Text Separators.
Eg: http://my-domain.com/(Alias)Main-menu-item/(Alias)Sub-Menu-(A)/(Alias)Sub-Menu(Sub-of-menu-A)
the question is,
How to omit [(Alias)Main-menu-item/(Alias)Sub-Menu-(A)/] parts in the Url without effecting the other urls in .htaccess.
ultimately url must look like

I'm using LinkedBlockingQueue declared as follows:
private BlockingQueue<OutgoingMessage> outgoingMessageQueue = new LinkedBlockingQueue<OutgoingMessage>();
OutgoingMessage represents text message to be sent to the customer. It gets in the queue by web service call that prepares it, saves it to database and puts it the queue. Application is deployed on tomcat so this thread a thread from HTTP pool.
I created different thread to process the queue and to do the actual message sending. It runs indefinitely and calls take() method on queue like this:
public void processOutgoingMessageQueue() {
try {
OutgoingMessage outgoingMessage = outgoingMessageQueue.take();
logger.debug(MessageFormat.format("Took outgoing message with id = [{0}] from queue", outgoingMessage.getId()));
this.forwardToCommunicator(outgoingMessage);
}
catch (InterruptedException e) {
logger.fatal("Interupted while waiting to process outgoing messages ", e); }
catch (Exception e) {
exceptionHandler.handle(e);
}
}
Method processOutgoingMessageQueue() is called from thread.
This is functional in a way that messages are put in the queue and later sent regularly but the client side (side that invoked web service method) doesn't get the response immediately after the outgoing message is put in the queue but rather when the thread that takes it from queue finishes it processing. It looks like the thread from the tomcat's HTTP pool is waiting for other thread to finish message processing and then returns web service response to the client.
This results in bad user experience as user has to wait for complete process to finish before he can enqueue another message.
Here is a log that shows that message was put in the queue successfully:
[DEBUG] 2012-07-08 23:09:51,707 [http-8080-8] SimpleServiceCommunicatorImpl: Received sendMessage request from serviceId = [3], charginId = [3], text [some text]

INFO 2012-07-08 23:10:06,477 SMSChatServiceImpl: Response message with result = 1366 sent to the customer
It shows that request returned after aprox 15 seconds from outgoing message was put in the queue, although there was no more work for the thread HTTP 8080-8 to perform.
Could this be a known tomcat or a LinkedBlockingQueue issue?
Does anyone have an idea? It more details are needed, I'll be glad to provide it.

public class Server extends Application {
@Override
public Restlet createInboundRoot() {
Router router = new Router(getContext());
//routes should be matched by uri_starts_with
router.setRoutingMode(Router.MODE_FIRST_MATCH);
router.setDefaultMatchingMode(Template.MODE_STARTS_WITH);
//router.setDefaultMatchingQuery(false);
router.attach("/save", WrapperServerResource.class);
TemplateRoute route = router.attach("/query/{name}?{gdat}?{svnr}", PatientServerResource.class);
Map<String, Variable> routeVariables = route.getTemplate().getVariables();
routeVariables.put("name", new Variable(Variable.TYPE_URI_QUERY_PARAM));
routeVariables.put("gdat", new Variable(Variable.TYPE_URI_QUERY_PARAM));
routeVariables.put("svnr", new Variable(Variable.TYPE_URI_QUERY_PARAM));
router.attachDefault(StandardResource.class);
return router;
}
}
Client Code:
public class PatientFetcher {
private String name, gdat, svnr;
public PatientFetcher(String name, String gdat, String svnr) {
this.name = name;
this.gdat = gdat;
this.svnr = svnr;
}
public List<Patient> fetch(Context ctx) {
Engine.getInstance().getRegisteredConverters().add(new JacksonConverter());
Engine.getInstance().getRegisteredClients().clear();

ClientResource cr = new ClientResource(DataUtil.getUriFetcher(ctx));
cr.setRequestEntityBuffering(true);
cr.addQueryParameter("name", name);
cr.addQueryParameter("gdat", gdat);
cr.addQueryParameter("svnr", svnr);
PatientResource resource = cr.wrap(PatientResource.class);

return repPList.getObject();
} catch (IOException e) {
Log.e("PatientFetcher", e.getMessage());
e.printStackTrace();
return null;
}
}
}
According to the GAE Log, the called URI (in this example svnr=1234, other fields are blank - but even if all fields are non-null, it isn't working) is `/query/?name=&gdat=&svnr=1234` which seems to be correct, but the Server's response (in `writer.toString()`) is the Default Route's `StandardResource.represent()` String, so I guess the issue is that Router does not match the calling URI to the PatientResource - what am I doing wrong?
There are no errors/warnings in the GAE log/android logcat except for a EOFException resulting from jackson not being able to deserialize the result string. The other route ("/save") is working fine.
(The `router.setDefaultMatchingQuery(false);` line does not seem to have any effect on the result, therefore it's commented out) | google-app-engine | restlet | router | null | null | null | open | Restlet GAE Router Template matching

The User_ID is following the Following_user_ID

(The User_ID column is the user that inserted the data into the tables.)
How would I build the query to select all of the activity rows where the currently logged in user is following the user in the User_ID column of Activity.
*EXAMPLE*
**Following**
>id = 1
>User_ID = 1
>Following_user_ID = 2
User 1 is following user 2
**Activity**
>A_ID = 1
>User_ID = 2
>Shared = Blah Blah
How can I make it so that user 1 (currently logged in) can see the activity of User 2 as user 1 is following user 2?
From the example above, user 1 should be able to see along the lines of "User 2 shared Blah Blah".
I have tried to explain this the best I can, have been trying to figure out the query but can't wrap my head around it.

Keeping true to the theme, I display the names of each person who has logged in to read that particular article and list their names before the login boxes (trying to create the feel of an actual guestbook). Of course, some users may want to log in but not have their real name displayed, so I added a checkbox allowing them to mark their name for obfuscation.
I thought the smoothest way to integrate this, since there is some value to having the correct number of 'signatures' on the 'guestbook', would be to have normal names appear in a standard script font (such as Brush Script), then have the lines for the 'hidden' names have what looks like handwriting, but that isn't actually readable.
The only way I could think to do this would be to find an unreadable font, define it in the css for the browser to download, then apply it to the hidden names. For good measure I can replace the real names with a random selection of "John Doe", "Jane Doe", "Jayne Doe", etc in case anyone views the source. However, after an hour of searching I've been unable to locate a font that meets my criteria, and I'm wondering if there's some better way to handle this problem.
So I was hoping someone could either suggest a font that might work for my needs, or suggest a better solution. Thank you. | html | css | fonts | webfonts | null | null | open | How to make text on a website appear handwritten, but unreadable

The problem I have is that I want to join 2 tables **with** a common indicator but include records where the common indicator also doesnt exist..
Maybe I'm making no sense, but I'll try to explain in code below
Table1
id | name
1 | John
2 | Michael
3 | Anna
4 | Sue
Table2
id | surname
1 | Doe
2 | Anderson
So I would like a query that outputs/binds the tables like so:
table1.id | table1.name | table2.id | table2.surname
1 | John | 1 | Doe
2 | Michael | 2 | Anderson
3 | Anna | NULL | NULL
4 | Sue | NULL | NULL
So, merge where there is data, and dont merge where this is no data (or add NULL value).
The table2 will always have less data than table1, so table1 could be used as a bone.
vlookup does this perfectly in excel, returns N/A where the value is not found
I know how to achieve this with PHP but I'm trying to speed up my code, when working with records well above the 50k I don't want to single query every row for another table column.
I've tried the WHERE table1.id=table2.id, but it only joins them if table2.id exists, I've also tried the JOIN ON function, but it does the same.

The [original proposal][1] explains that the standard `regex_traits::transform_primary()` can only work if the `collate` facet in the imbued locale was not replaced by the user (that's the only way it can know how to convert the result of `collate::transform()` to the equivalence key).
My question is, how is the `typeid` comparison in the standard supposed to ensure that? Does it imply that all system-supplied facets pulled out of locales with `use_facet` have `_byname` as their true dynamic types?

else

{

private static boolean responseSuccessful = true;
/**

}
And here is my XML just for kicks:
<?xml version="1.0" encoding="utf-8"?>

</manifest>
I have used the HttpHelper class in past projects and it has worked for me, in addition I tried to implement this using nameValuePairs:
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("email", "[email protected]"));
nameValuePairs.add(new BasicNameValuePair("password", "password1"));
nameValuePairs.add(new BasicNameValuePair("json", "true"));
try {
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
And this yielded the same result.
Could this somehow be a certificate thing? or perhaps something to do with a corrupt XML file( I tried remaking the project and the xml file) http://stackoverflow.com/q/9469060/1437824
Or maybe some sort of Android hosts file issue?
I'm open to any suggestions!
I have examined this from a lot of angles and I'm happy to provide any other information that would be helpful! I really appreciate your time!

Internet permission IS enabled in my XML manifest file
My current implementation goes like this:

String PASSWORD ="password1";
//JSONObject to send the username and pw
JSONObject json = new JSONObject();
//put the path in the JSONArray object
JSONArray vect = new JSONArray();
vect.put("Callisto Android Library");

e.printStackTrace();
}
Log.d(TAG, "ABOUT TO SEND:" + json.toString());
JSONObject inJson = HttpHelperAndroid.sendToHttp(json, "http://devdashboard.company/login");
if(inJson != null)
{
Log.d(TAG, "RECIEVED the JSON:" + inJson.toString());
}
else
Log.d(TAG, "THE RESPONSE WAS NULL");
}
And the HttpHelperAndroid class looks like so:
public class HttpHelperAndroid
{
private static final String TAG = "HttpHelperAndroid";//TAG for the LogCat(debugging)
private static boolean responseSuccessful = true;
/**
* sends the JSONObject parameter to the desired URL parameter and gets the response
*

//convert the JSONObject to a string

//set our StringEntity to the JSONObject as a string

//execute the http request and get the response
response = (HttpResponse) httpClient.execute(httpRequest);
}
catch(HttpHostConnectException e)
{
System.err.println("Unable to connect to the server");
e.printStackTrace();
responseSuccessful = false;
}
//only continue executing if we got a response from the server
if(responseSuccessful)
{
//print how long the response took to the LogCat if it's on
Log.i(TAG, "HTTPResponse received in [" + (System.currentTimeMillis()-oldTime) + "ms]");
// Get hold of the response entity (-> the data):

if (entity != null) {

}
// convert content stream to a String

//close the stream
in.close();
// convert the String into a JSONObject
JSONObject jsonObjRecv = new JSONObject(resultString);
//take a peak at the JSONObject we got back if the LogCat is on
Log.i(TAG,"<JSONObject>\n"+jsonObjRecv.toString()+"\n</JSONObject>");
//return the JSONObject we got back from the server
return jsonObjRecv;
}
}
}
//catch any exception that was thrown
catch (Exception e)
{
//Print the exception

}
return null;
}
private static String streamToString(InputStream is)
{
//create a new BufferedReader for the input stream
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
//create a new StringBuilder to append the lines
StringBuilder sb = new StringBuilder();
//initialize an empty string
String line = null;
try
{
//iterate as long as there is still lines to be read
while ((line = reader.readLine()) != null)
{
//append the line and a newline character to our StringBuilder
sb.append(line + "\n");
}
}
//catch an IOException and print it
catch (IOException e) {
e.printStackTrace();
}
//close the stream when we're done
finally
{
try
{
is.close();
}
//catch and print an exception if it's thrown
catch (IOException e)
{
e.printStackTrace();
}
}
//return the stream converted to a string
return sb.toString();
}
}
And here is my XML just for kicks:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="callisto.fm.android.dashboard.app"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-sdk android:minSdkVersion="7" />
<application
android:icon="@drawable/company_android_ico"
android:label="@string/app_name" >
<activity
android:name=".DashboardAppActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I have used the HttpHelper class in past projects and it has worked for me, in addition I tried to implement this using nameValuePairs:
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("email", "[email protected]"));
nameValuePairs.add(new BasicNameValuePair("password", "password1"));
nameValuePairs.add(new BasicNameValuePair("json", "true"));
try {
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
And this yielded the same result.
Could this somehow be a certificate thing? or perhaps something to do with a corrupt XML file( I tried remaking the project and the xml file) http://stackoverflow.com/q/9469060/1437824
Or maybe some sort of Android hosts file issue?
I'm open to any suggestions!
I have examined this from a lot of angles and I'm happy to provide any other information that would be helpful! I really appreciate your time!

I have spent a lot of time to display an Enum into a listpicker an now I see InvalidCastException when trying to bind to the (IsolatedStorage) object.
public class Bath {
public string Colour { get; set; }
public WaterType WaterType { get; set; }
}
public enum WaterType {
Hot,
Cold
}
The enum is bound to a ListPicker, but as there is not enum.GetValues() in WP7 this is not a simple task.
I have a simple type class...
public class TypeList
{
public string Name { get; set; }
}
And in my viewmodel, I have ObservableCollection and mock the values from the enum...
private ObservableCollection<TypeList> _WaterTypeList;
public ObservableCollection<TypeList> WaterTypeList
{
get { return _WaterTypeList; }
set
{
_WaterTypeList= value;
NotifyPropertyChanged("WaterTypeList");
}
}
public void LoadCollectionsFromDatabase()
{
ObservableCollection<TypeList> wTypeList = new ObservableCollection<WaterTypeList>();
wTypeList.Add(new TypeList{ Name = WaterType.Hot.ToString() });
wTypeList.Add(new TypeList{ Name = WaterType.Income.ToString() });
WaterTypeList = new ObservableCollection<TypeList>(wTypeList);
}
Finally, my xaml contains the listbox...
<toolkit:ListPicker
x:Name="BathTypeListPicker"
ItemsSource="{Binding WaterTypeList}"
DisplayMemberPath="Name">
</toolkit:ListPicker>
Im not sure if the above is best practise and indeed if the above is part of the problem but the above does give me a populated ListPicker.
Finally, when the form is submitted the cast causes a InvalidCastException.
private void SaveAppBarButton_Click(object sender, EventArgs e)
{
var xyz = WaterTypeList.SelectedItem; // type AppName.Model.typeList
Bath b = new Bath
{
Colour = ColourTextBox.Text ?? "Black",
WaterType = (WaterType)WaterTypeListPicker.SelectedItem
};
App.ViewModel.EditBath(b);
NavigationService.Navigate(new Uri("/Somewhere.xaml", UriKind.Relative));
}
}
Has anyone faced a simlar problem and can offer advice. I see that my opions are to concentrate on casting something meaningful from the ListPicker or should I rethink the way that the ListPicker is populated?

We have a vendor-supplied web application that, among other things, allows online payments--intended for use by "the public" over the intERnet, from outside our building and network. We have PC's that are intentionally accessible to the public throughout our organization. We would like to make this vendor application available from these public PC's; however, to protect ourselves from users inadvertently exposing their personal, financial information to subsequent users, we would like to disable the payment functionality of the application--using the same installation of the site as is used for external access (if that's not too crazy).
My first stab at accomplishing this has been to create a cookie on these public PC's. I have added javascript to the vendor .aspx that hides the "Pay" button if the cookie exists.
This works and feels relatively reliable, assuming we control the browser installation and prohibit public users from deleting cookies. However, since there are many other ways cookies could get inadvertently deleted (i.e., maintenance, upgrades, etc.), I am not entirely comfortable with this approach.
I am struggling to come up with another, more reasonable and reliable solution, so I am just sort of throwing this out here for suggestions, brainstorming. The solution will likely have to be a sort-of backdoor something similar to the above since the vendor has not been forthcoming with a solution.
I have considered evaluating IP addresses; however, I am not certain how to tell if the PC is from inside or outside our network. (Although, I did see a post for pinging an internal destination as one means; this in conjuction with a fixed IP check may be a possibility.)
I realize (and am embarrassed that) this is kind of out there--there is probably a whole lot wrong with what we're trying to accomplish. Regardless, any [not too cruel] direction or suggestions will be greatly appreciated.

Something like this:
- (void)setContentData:(NSData *)contentData
{
NSString *base64String;
// do some stuff to convert data to base64-encoded string
// ...
[self willChangeValueForKey:@"contentData"];
[self setPrimitiveValue:base64String forKey:@"contentData"];
[self didChangeValueForKey:@"contentData"];
}
So, in this case the `contentData` field of my `NSManagedObject` is an `NSString *`, and I want to allow the setter to accept an `NSData *` which I would then convert to an `NSString *` and save it to the model. However, if I try to do this I get warnings from the compiler about trying to assign an `NSData *` to an `NSString *`:
myObject.contentData = someNSData;
-> Incompatible pointer types assigning to 'NSString *' from 'NSData *__strong'
Is there a better way to go about this, or perhaps I should avoid the setters altogether and create custom "setters" that allow me to pass in the `NSData *` and set the `NSString *` field without a compiler warning? | objective-c | ios | null | null | null | null | open | Objective C - Override setter to accept objects of a different type

Now I know in Direct2D I can apply matrix transformations to accomplish this... but I'm not exactly sure how. The examples I've seen are more about applying specific transformations (e.g. rotate 30 degrees) than trying to match an exact destination.
Given that I know the exact coordinates (A,B,C,D) above, is there an easy way to map the source image onto the target? Alternately how would I generate the matrix given the source and destination coordinates? | matrix | directx | direct2d | sharpdx | srt | null | open | Mapping corners to arbitrary positions using Direct2D

In each area, it has its own Controllers, Models, Views folders. At the root Models, root Controllers and root Views I have shared components in them.
Structure A:
Root/ -> Models/, Controllers/, Views/
Root/User/ -> Models/, Controllers/, Views/
Root/Admin/ -> Models/, Controllers/, Views/
Root/Shop/ -> Models/, Controllers/, Views/
Root/Forum/ -> Models/, Controllers/, Views/
I maybe wrong, but they really don't look DRY to me to repeat M V and C folders in each of the business logic groups. I was thinking a better structure would be using M V and C as the main folders and layout my business logic groups in them:
Structure B:
Root/Views/ -> User/, Admin/, Shop/, Forum/ ...etc
Root/Models/ -> User/, Admin/, Shop/, Forum/ ...etc
Root/Controllers/ -> User/, Admin/, Shop/, Forum/ ...etc
But if I do structure the folders this way, I lost the area (or from users point of view, the sub folder path) ability to divde logical functionalities of the website.
e.g.
with structure A, I can do:
www.mywebsite.com/Users(area)/Account(controller)/LogOn(action)
www.mywebsite.com/Admin(area)/Account(controller)/LogOn(action)
Notice I can have same controller and action names with different areas.
With structure B, best I can do is:
www.mywebsite.com/AdminAccount(controller)/LogOn(action)
www.mywebsite.com/UserAccount(controller)/LogOn(action)
It can not achieve the single-word sub-folder result without area. If not only that, the controller names here can get longer and more messy very soon. Not to mention you have a large group of actions stacking in same controller.cs file.
So, anyway, my point is, if I find Structure B making more sense to me, how do I go about configuring routing to achieve that?

Basically I've been trying to implement a way to send request to twitter oauth resources via javascript. I have a server running a Django application which uses Django-social-auth to register users to Tiwtter. After I've obtained authorisation I get a users access_token and oauth_token_secret.
On the client side I have a javascript application which calls my server to compute the appropriate headers, which I do by using [python oauth2][2]. The piece of code doing this is as follows:
url = request.POST['url']
params = {
'oauth_version': "1.0",
'oauth_nonce': oauth.generate_nonce(),
'oauth_timestamp': int(time.time()),
}
at = social.extra_data['access_token'].split('&oauth_token=')[1]
ats = social.extra_data['access_token'].split('&oauth_token=')[0].split('oauth_token_secret=')[1]
token = oauth.Token(key=at, secret=ats)
consumer = oauth.Consumer(key=settings.TWITTER_CONSUMER_KEY, secret=settings.TWITTER_CONSUMER_SECRET)
params['oauth_token'] = token.key
params['oauth_consumer_key'] = consumer.key
req = oauth.Request(method="GET", url=url, parameters=params)
signature_method = oauth.SignatureMethod_HMAC_SHA1()
req.sign_request(signature_method, consumer, token)
This request parameters are then sent to the client which does the call to Twitter using these parameters:
$.ajax({
url: "https://api.twitter.com/1/statuses/home_timeline.json",
data: parameters,
dataType: 'jsonp',
success: function(twitter_data) {
console.log('twitter_data = ', twdata);
},
error: function(jqXHR, textStatus, errorThrown) {
console.log('err = ', textStatus);
console.log('err = ', errorThrown);
}
});
which generates a request for a resource like:
https://api.twitter.com/1/statuses/home_timeline.json?callback=jQuery17107030615725088865_1341786299930&oauth_nonce=15094349&oauth_timestamp=1341785696&oauth_consumer_key=[OAUTH_CONSUMER_KEY HERE]&oauth_signature_method=HMAC-SHA1&oauth_version=1.0&oauth_token=[OAUTH_TOKEN HERE]0&oauth_signature=pQwHlKmepgtym%2Ffj%2BupCGP8mv3s%3D&page=2&include_entities=true&_=1341786306712
Still I get a 401 Unauthorized error. I checked the code three times so am wondering if I missing something???

My call to curl_exec($ch) kept returning false. After a few days of racking my brain, reading and searching the web it seems I finally figured it out. I had to use GET instead of POST, I found that [here][2], and I had to NOT verify the SSL. (I can't remember where I found that...)
I hope this helps someone who's having the same problem. And please, if anyone can improve upon this their corrections are more then welcome.
This is what was suggested by the thread linked to above:
$ch = curl_init();
// WRITE MESSAGE TO SEND TO JSON OBJECT
$message = '{"data":{"message":"here is the message","title":"message title"},"registration_ids":["'. $reg . '","'. $reg2 . '"]}';
curl_setopt($ch, CURLOPT_POSTFIELDS, $message);

curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// WRITE JSON HEADERS
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Authorization:key=' . $apiKey)
);
$result = curl_exec($ch);
if(!$result > 0){
echo "<p>An error has occurred.<p>";
echo "<p>ERROR: $curl_error</p>";
}
else{
$json_return = json_decode($result);
echo var_dump($json_return);
$info = curl_getinfo($ch);;
echo "<p>httpcode: " . $info['http_code'] . "</p>";
}
curl_close($ch);
For me to get this working I have to implement the following.
$ch = curl_init();
$message = '{"data":{"message":"here is the message","title":"message title"},"registration_ids":["'. $reg . '","'. $reg2 . '"]}';
curl_setopt($ch, CURLOPT_POSTFIELDS, $message);

I hope this helps someone who's having the same problem. And please, if anyone can improve upon this their corrections are more then welcome.
This is what was suggested by the thread linked to above:
$ch = curl_init();
// WRITE MESSAGE TO SEND TO JSON OBJECT
$message = '{"data":{"message":"here is the message","title":"message title"},"registration_ids":["'. $reg . '","'. $reg2 . '"]}';
curl_setopt($ch, CURLOPT_POSTFIELDS, $message);
curl_setopt($ch, CURLOPT_URL, $gcmurl);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// WRITE JSON HEADERS
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Authorization:key=' . $apiKey)
);
$result = curl_exec($ch);
if(!$result > 0){
echo "<p>An error has occurred.<p>";
echo "<p>ERROR: $curl_error</p>";
}
else{
$json_return = json_decode($result);
echo var_dump($json_return);
$info = curl_getinfo($ch);;
echo "<p>httpcode: " . $info['http_code'] . "</p>";
}
curl_close($ch);
For me to get this working I have to implement the following.
$ch = curl_init();
$message = '{"data":{"message":"here is the message","title":"message title"},"registration_ids":["'. $reg . '","'. $reg2 . '"]}';
curl_setopt($ch, CURLOPT_POSTFIELDS, $message);
curl_setopt($ch, CURLOPT_URL, $gcmurl);
/*
* COMMENT OUT THE FOLLOWING LINE
*/
*//curl_setopt($ch, CURLOPT_POST, true);*
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// WRITE JSON HEADERS
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Authorization:key=' . $apiKey)
);
/*
* ADD THESE 2 LINES
*/
curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
$result = curl_exec($ch);
if(!$result > 0){
echo "<p>An error has occurred.<p>";
echo "<p>ERROR: $curl_error";
}
else{
$json_return = json_decode($result);
echo var_dump($json_return);
$info = curl_getinfo($ch);;
}

I wanted to use a tableview with a limited number of rows (say 50 max). It starts of empty, with 0 rows. Then I wanted to do something along the lines of:
[self logMessage:@"Waiting for response"];
Which inserts a new row at the bottom with the above text. If I do another call to this pseudo function:
[self logMessage:@"Server response received"];
It should insert yet another new row below the previous row, and ensure it is visible. Once the above limit of 50 is reached, and a new message is inserted, I wanted the oldest message to be removed. All of this would be scrollable, with the latest being visible by default.
Am I looking at the right thing to do this? Eventually, I was hoping to have this in a nice little drawer below the main window, which I can then toggle from the main menu if needed. But as I said, I can't work out how to use a table view properly, it doesn't seem to be as straight forward as other objects are.
Any example code would be greatly appreciated!

I have a collection of sport tournaments and each of it has many events and each event has 3 entities that i call "outcome". My task is to show all of them in one table. Following template show how i need this table to be show.
{{#tournaments}}
<h2>{{name}}</h2>
<table class="event_list">
{{#events.find_all}}
<tr>
<td>{{day}}</td>
{{#outcomes.find_all}}
<td class="outcome">{{name}}</td>
{{/outcomes.find_all}}
</tr>
{{/events.find_all}}
</table>
{{/tournaments}}
And now goes my problem and thus question. While showing "outcomes" i need to attach additional different classes to each <td>. So i mean i have 3 "outcomes" for each event and thus i have 3 different CSS classes for each of them. But inside {{#outcomes.find_all}} loop i have no clue is it first entity or second or third. What can i do about this?
Trying to solve this I was thinking about using functions. I thought of adding function to this view's class that would render all events "outcomes" and this may look like this:
{{#tournaments}}
<h2>{{name}}</h2>
<table class="event_list">
{{#events.find_all}}
<tr>
<td>{{day}}</td>
{{print_outcomes}}
</tr>
{{/events.find_all}}
</table>
{{/tournaments}}
But obviously i will need to pass collection of "outcomes" in that function and then i realized that i can't pass anything in that function. So how such problems solved in mustache? | mustache | kohana-3.2 | null | null | null | null | open | nested data in mustache template

For example, each vector has two elements, V = {v[0], v[1]}, such as {age, height},where age ranges from 30 to 70, and height ranges from 100cm - 200 cm, two example vectors, v1 = {20, 175}, v2 = {35,192} are given.
I know that cosine similarity (sim) is defined as sim = (v1 dot v2 ) / (|v1| * |v2|), where dot is the dot product between v1 and v2, |v| is the magnitude of a vector. But this is based on the assumption of the each element in vector V has same range of data and it is not applied when each element has different range, such as the case I used here.
One thing I can think of is to apply a weights vector W = {w[0],w[1]} to each vector v1, and v2 here to normalize each element in vector.
That is
weighted_sim = ( sum (w[i] * v1[i] * v2[i]) ) / sqrt ( (sum (w[i] *v1[i]^2 ) ) * ( sum (w[i] *v2[i]^2 ) ) )
But I have difficult to figure out the weights vector W here.
Could someone help me here? Thanks a lot.

The variable is actually passed to the function from another. What gets passed, though, may be either a numerical value, or a string value.
So basically I have:
$inverse = 1/$number;
Where `$number` may be either a valid number, or a string.
My question is what happens when `$number` is a string? How does php handle that situation?
Ultimately the answer isn't too important; I can think of a couple of different ways of working around the situation. It's just that it came up, I got curious, and a quick google search couldn't answer my question. Even if I don't need to know the answer, I'd like to know the answer, because understanding how PHP works will help me in the future.

In short, I want to visualize election data. How many votes did parties get, and what scenario's are possible to form a government?
At the data level, it's quite obvious: Name, number of seats in parliament, state1, state2, state3, etc. State1 is a 1 or 2. 1 is a place in government, 2 is opposition. Pretty straightforward.
But the example only shows two states: All Grants and Grants By year. What I want, is more states like Grants By Year. But me being not a very good programmer can't figure out how to make this work. The visualisation doesn't work when I add a new state.

===
I want to use this ([http://vallandingham.me/vis/gates/][1]) Bubble Chart (made in D3) to walk through some different scenarios. In short, I want to visualize election data. How many votes did parties get, and what scenario's are possible to form a government?
At the data level, it's quite obvious: Name, number of seats in parliament, state1, state2, state3, etc. State1 is a 1 or 2. 1 is a place in government, 2 is opposition. Pretty straightforward.
But the example only shows two states: All Grants and Grants By year. What I want, is more states like Grants By Year. But me being not a very good programmer can't figure out how to make this work. The visualisation doesn't work when I add a new state.
Here's the code (Coffee) which controls states.
class BubbleChart

@data = data
@width = 940
@height = 600
@tooltip = CustomTooltip("gates_tooltip", 240)

# used
@center = {x: @width / 2, y: @height / 2}

"2008": {x: @width / 3, y: @height / 2},
"2009": {x: @width / 2, y: @height / 2},
