  • Proving that the distance values extracted in Dijkstra's algorithm is non-decreasing?

    - by Gail
    I'm reviewing my old algorithms notes and have come across this proof. It was from an assignment I had and I got it correct, but I feel that the proof certainly lacks. The question is to prove that the distance values taken from the priority queue in Dijkstra's algorithm is a non-decreasing sequence. My proof goes as follows: Proof by contradiction. Fist, assume that we pull a vertex from Q with d-value 'i'. Next time, we pull a vertex with d-value 'j'. When we pulled i, we have finalised our d-value and computed the shortest-path from the start vertex, s, to i. Since we have positive edge weights, it is impossible for our d-values to shrink as we add vertices to our path. If after pulling i from Q, we pull j with a smaller d-value, we may not have a shortest path to i, since we may be able to reach i through j. However, we have already computed the shortest path to i. We did not check a possible path. We no longer have a guaranteed path. Contradiction.

  • Discover periodic patterns in a large data-set

    - by Miner
    I have a large sequence of tuples on disk in the form (t1, k1) (t2, k2) ... (tn, kn) ti is a monotonically increasing timestamp and ki is a key (assume a fixed length string if needed). Neither ti nor ki are guaranteed to be unique. However, the number of unique tis and kis is huge (millions). n itself is very large (100 Million+) and the size of k (approx 500 bytes) makes it impossible to store everything in memory. I would like to find out periodic occurrences of keys in this sequence. For example, if I have the sequence (1, a) (2, b) (3, c) (4, b) (5, a) (6, b) (7, d) (8, b) (9, a) (10, b) The algorithm should emit (a, 4) and (b, 2). That is a occurs with a period of 4 and b occurs with a period of 2. If I build a hash of all keys and store the average of the difference between consecutive timestamps of each key and a std deviation of the same, I might be able to make a pass, and report only the ones that have an acceptable std deviation(ideally, 0). However, it requires one bucket per unique key, whereas in practice, I might have very few really periodic patterns. Any better ways?

  • calll html button onclick event from asp server side login authenticate event

    - by CraigJSte
    Need to programmatically click an html button from a login event (code behind? the html button sends variables to Flash using method: no response - with no postback and uses ExternalInterface API via javascript. Going from SWF ASPX is great, but need to send User.Identity to SWF from ASPX via javascript after authenticate with login event which am having impossible time getting to work... (calling HTML event from Login button) tried scripting in javascript to login event with no luck, possibly because postback clears SWF variables - so perhaps keeping separate (login then html send) would work... Here is my relevant code: function sendToActionScript(value) { swfobject.getObjectById("Property").sendToActionScript(value); } </script> <object ..// SWF File embedded> </object <form id="form1" runat="server"> <asp:Login id="login1" OnAuthenticate="login1_Authenticate"/> </form> <form id="form" onsubmit="return false;"> <input type="text" name="input" id="input" value="" runat="server" /> <button id="btnInput" runat="server" causesvalidation="false" visible="true" style="width: 51px" onclick="sendToActionScript(this.form.input.value);" >Send</button><br /> </form> // CODE BEHIND protected void Login1_Authenticate(object sender, AuthenticateEventArgs e) { // do something to get User Id and Role //bind the string (user or role) to input.value //then call the HTML button onclick event to send it to SWF file. //which I could put in separate function and call from Login_Authenticate } Can anyone help me I am out of ideas.

  • ContextMenu not popping up on Long click

    - by primal
    Hi, The context menu is not popping up on the long click on the list items in the list view. I've extended the base adapter and used a view holder to implement the custom list with textviews and an imagebutton. adapter = new MyClickableListAdapter(this, R.layout.timeline, mObjectList); list.setAdapter(adapter); registerForContextMenu(list); Implementation of onCreateContextMenu @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { // TODO Auto-generated method stub super.onCreateContextMenu(menu, v, menuInfo); Log.d(TAG, "Entering Context Menu"); menu.setHeaderTitle("Context Menu"); menu.add(Menu.NONE, DELETE_ID, Menu.NONE, "Delete") .setIcon(R.drawable.icon); } The XML for listview is here <ListView android:id="@+id/list" android:layout_width="fill_parent" android:layout_height="wrap_content" /> I've been trying this for many days. I think its impossible to register Context-menu for a custom list view like this. Correct me if I am wrong (possibly with sample code). Now I am thinking of a adding a button to the list item and it displays a menu on clicking it. Is it possible with some other way than using Dialogs? Any help would be much appreciated..

  • What are practical guidelines for evaluating a language's "Turing Completeness"?

    - by AShelly
    I've read "what-is-turing-complete" and the wikipedia page, but I'm less interested in a formal proof than in the practical implications of being Turing Complete. What I'm actually trying to decide is if the toy language I've just designed could be used as a general-purpose language. I know I can prove it is if I can write a Turing machine with it. But I don't want to go through that exercise until I'm fairly certain of success. Is there a minimum set of features without which Turing Completeness is impossible? Is there a set of features which virtually guarantees completeness? (My guess is that conditional branching and a readable/writeable memory store will get me most of the way there) EDIT: I think I've gone off on a tangent by saying "Turing Complete". I'm trying to guess with reasonable confidence that a newly invented language with a certain feature set (or alternately, a VM with a certain instruction set) would be able to compute anything worth computing. I know proving you can building a Turing machine with it is one way, but not the only way. What I was hoping for was a set of guidelines like: "if it can do X,Y,and Z, it can probably do anything".

  • Time complexity with bit cost

    - by Keyser
    I think I might have completely misunderstood bit cost analysis. I'm trying to wrap my head around the concept of studying an algorithm's time complexity with respect to bit cost (instead of unit cost) and it seems to be impossible to find anything on the subject. Is this considered to be so trivial that no one ever needs to have it explained to them? Well I do. (Also, there doesn't even seem to be anything on wikipedia which is very unusual). Here's what I have so far: The bit cost of multiplication and division of two numbers with n bits is O(n^2) (in general?) So, for example: int number = 2; for(int i = 0; i < n; i++ ){ number = i*i; } has a time complexity with respect to bit cost of O(n^3), because it does n multiplications (right?) But in a regular scenario we want the time complexity with respect to the input. So, how does that scenario work? The number of bits in i could be considered a constant. Which would make the time complexity the same as with unit cost except with a bigger constant (and both would be linear). Also, I'm guessing addition and subtraction can be done in constant time, O(1). Couldn't find any info on it but it seems reasonable since it's one assembler operation.

  • Visual Studio 2008 project file does not load because of an unexpected encoding change.

    - by Xenan
    In our team we have a database project in visual Studio 2008 which is under source control by Team Foundation Server. Every two weeks or so, after one co-worker checks in, the project file won't load on the other developers machines. The error message is: The project file could not be loaded. Data at the root level is invalid. Line 1, position 1. When I look at the project file in Notepad++, the file looks like this: ??<NUL?NULxNULmNULlNUL NULvNULeNULrNULsNULiNULoNULnNUL ... and so on (you can see <?xml version in this) whereas an normal project file looks like: <?xml version="1.0" encoding="utf-16"?> ... So probably something is wrong with the encoding of the file. This is a problem for us because it turns out to be impossible to get the file encoding correct again. The 'solution' is to throw away the project file an get the last know working version from source control. According to the file, the encoding should be UTF-16. According to Notepad++, the corrupted file is actually UTF-8. My questions are: Why is Visual Studio messing up the encoding of the project file, apparently at random times and at random machines? What should we do to prevent this? When it has happened, is there a possibility to restore the current file in the correct encoding instead of pulling an older version from source control? As a last note: the problem is with one single project file, all other project files don't expose this problem.

  • Using a Javascript Variable & Sending to JSON

    - by D Franks
    Hello all! I'm trying to take a URL's hash value, send it through a function, turn that value into an object, but ultimately send the value to JSON. I have the following setup: function content(cur){ var mycur = $H(cur); var pars = "p="+mycur.toJSON(); new Ajax.Updater('my_box', 'test.php', { parameters: pars }); } function update(){ if(window.location.hash.length > 0){ content(window.location.hash.substr(1)); // Everything after the '#' } } var curHashVal = window.location.hash; window.onload = function(){ setInterval(function(){ if(curHashVal != window.location.hash){ update(); curHashVal = window.location.hash; } },1); } But for some reason, I can't seem to get the right JSON output. It will either return as a very large object (1:"{",2:"k") or not return at all. I doubt that it is impossible to accomplish, but I've exhausted most of the ways I can think of. Other ways I've tried were "{" + cur + "}" as well as cur.toObject(), however, none seemed to get the job done. Thanks for the help!

  • running .net application over a network

    - by Marlon
    Hello, I need some advice please. I need to enable a .Net application to run over a network share, the problem is that this will be on clients network shares and so the path will not be identical. I've had a quick look at ClickOnce and the publish options in VS2008 but it wants a specific network share location - and I'm assuming this location gets stored somewhere when it does its thing. At the moment the job is being done with a old VB6 application and so gets around all these security issues, but that application is poorly written and almost impossible to maintain so it really needs to go. Is it possible for the domain controller to be set up to allow this specific .Net application to execute? Any other options would be welcomed as I want to get this little application is very business critical. I aught to say that the client networks are schools, and thus are often quite locked down as are the client machines, so manually adding exceptions to each client machine is a big no no. Marlon --Edit-- Apologies, I forgot to mention we're restricted to .net 2.0 for the moment, we are planning to upgrade this to 4.0 but that won't be immediate.

  • How to post a poll on the Facebook wall

    - by Bengt
    Hi, I'm trying to convert my poll app into a Facebook iframe app. My app is written in PHP and uses some Ajax calls to vote at a poll. In the application canvas everything is working fine, but of course I want to get the poll on the wall of a user too. Unfortunately I'm not able to find out how I can post a simple poll with some radio buttons for the options on the wall. I know how to publish images, text, audio files and links to the wall, but I have no idea how to publish my poll on the wall. And I don't just want to use links to vote, I want the user be able to choose a radio button. Does anyone have an idea how to do this or where to find information about doing this? I'm stuck there now for a while and it gets pretty frustrating. I'm using the new Graph API by the way. Or is this impossible? But I don't think so. Any help is appreciated. Bengt

  • Quitting an application - is that frowned upon?

    - by Ted
    Moving on in my attempt to learn Android I just read the following: Question: Does the user have a choice to kill the application unless we put a menu option in to kill it? If no such option exists, how does the user terminate the application? Answert (Romain Guy): The user doesn't, the system handles this automatically. That's what the activity lifecycle (especially onPause/onStop/onDestroy) is for. No matter what you do, do not put a "quit" or "exit" application button. It is useless with Android's application model. This is also contrary to how core applications work. Hehe, for every step I take in the Android world I run into some sort of problem =( Apparently, you cannot quit an application in Android (but Android can very well totally destroy your app whenever it feels like it). Whats up with that? I am starting to think that its impossible to write an app that functions as a "normal app" - that the user can quit the app when he/she decides to do so. That is not something that should be relied upon the OS to do. The application I am trying to create is not an application for the Android Market. It is not an application for "wide use" by the general public, it is a business app that is going to be used in a very narrow business field. I was actually really looking forward to developing for the Android-platform, since it addresses a lot of issues that exist in Windows Mobile and .NET. However, the last week has been somewhat of a turnoff for me... I hope I dont have to abandon Android, but it doesnt look very good right now =( Is there a way for me to really quit the application?

  • Xcode 5 - remove storyboard and start app with a .xib

    - by Lucy
    I've tried to follow the instructions on this Question. But I must not be doing something correctly because I am still getting a SIGABRT before I even get into the ViewController methods. Here are the steps: Copied all items on the view in the story board and pasted into the new xib view. Copied all contents of .h and .m view controller files into the new ones for the xib. Changed the Main nib file base name to the new xib name in the info.plist file. Tried to change the owner but I don't know if I'm doing that correctly. Edited the appdelegate didFinishLaunchingWithOptions file as follows: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] ; // Override point for customization after application launch. TestViewController *test = [[TestViewController alloc] initWithNibName:@"TestViewController" bundle:nil]; UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:test]; self.window.rootViewController = nav; [self.window makeKeyAndVisible]; return YES; } I even tried to start with an empty project like one of the last posts suggested and still get a SIGABRT when I try to run. Has Apple made it impossible to remove the storyboard? I'm creating an SDK. I don't want a storyboard. But I do need one xib that is rotatable. Help?

  • javascript plugin - singleton pattern?

    - by Adam Kiss
    intro Hello, I'm trying to develop some plugin or/*and* object in javascript, which will control some properties over some object. It will also use jQuery, to ease development. idea This is in pseudocode to give you an idea, since I can't really describe it in english with the right words, it's impossible to go and use google to find out what I want to use (and learn). I will have plugin (maybe object?) with some variables and methods: plugin hideshow(startupconfig){ var c, //collection add: function(what){ c += what; }, do: function(){ c.show().hide().stop(); //example code } } and I will use it this way (or sort-of): var p = new Plugin(); p .add($('p#simple')) .add($('p#simple2')) .do(); note I'm not really looking for jQuery plugin tutorials - it's more like usage of singleton pattern in document in javascript, jQuery is mentione only because it will be used to modify dom and simplify selectors, jQuery plugin maybe just for that one little function add. I'm looking for something, that will sit on top of my document and call functions from itselft based on timer, or user actions, or whatever. problems I don't really know where to start with construction of this object/plugin I'm not really sure how to maintain one variable, which is collection of jQuery objects (something like $('#simple, #simple2');) I would maybe like to extedn jQuery with $.fn.addToPlugin to use chaining of objects, but that should be simple (really just each( p.add($(this)); )) I hope I make any sense, ideas, links or advices appreciated.

  • Can I specify the files to commit in subversion in a file rather than on the command line?

    - by René Nyffenegger
    I have renamed (with svn move) a lot of files in a subversion project. Now, I am trying to commit these on Window's cmd.exe. It seems that I hit a limit (probably by cmd.exe) in that the number of files is too long for the command line to swallow. Now, I thought and hoped that I could list the files to commit in a seperate file that I could specify with the commit command (something like svn ci --files-to-commit=renamed-files.txt -m "Renamed a lot of files" Yet, either such an option does not exist or I am unable to find this. Unfortunately, I cannot do a svn ci . as I have done other changes in the project as well. Neither can I do a svn ci *pattern-of-renamed-files* since this would only check in the added files, not the deleted ones. Before I start checking in the files with smaller chunks of files to check in (and thus increase the revision number uneccesserily without giving a hint as to the 'atomicity' of the operation) I thought I ask if this is indeed impossible to do.

  • protecting COM interfaces from exceptions

    - by rmeador
    I have several dozen objects exposed through COM interfaces, each of which with many methods, totaling a few hundred methods. These interfaces expose business objects from my app to a scripting engine. I have been given the task of protecting every single one of these methods from exceptions being thrown (to catch them and return an error using COM's Error() function, which incidentally I can find no documentation on because it's impossible to google). To my understanding, this requires that I add a try/catch around the guts of each one of these methods. The catch blocks are going to be similar or identical for each and every one of these hundreds of methods, which strongly smells of a problem (massively violates the DRY principle), but I can't think of any way to avoid changing every method. As far as I can tell, these methods are invoked directly by COM, with no intervening code that I can hook into to catch the exceptions. My current best idea is to make a macro for the catch block, but that has it's own sort of code-smell. Can anyone come up with a better approach? BTW, my app's exceptions do not derive from std::exception, so if there is some way of COM automatically handling standard exceptions, it won't help. And I sadly cannot change the existing exceptions to derive from std::exception.

  • iphone crash log with dSym not loading debug information

    - by AngeDeLaMort
    Hello, I was trying to see why my application crashed on the device (iPhone) using the dSym generated along the executable (in ad hoc), but I don't know why, there isn't any useful information. It seems that "Organizer" is able to find the appropriate dSym and translate some data into more readable one, but when it comes to my application, I just have an address. Since I know how to reproduce it, I've tried to setup my build so it can help me in the future. So, I've tried to find if I had all the proper flags set int the project build properties and everything seems fine. So after doing some research, it seems that all information are stripped during link time and the dSym seems completely useless. I've played with some flags, but nothing changed. So, is there something special to do in order to get the crash file human readable? Or is it impossible in the ad hoc setting? The closest thing near to work that I've done was to build a debug version and look up the address in it. At least it seems to give the right file. So, I made a sample app and here what I have: (the line I want is #4): Thread 0 Crashed: 0 libobjc.A.dylib 0x00003ebc objc_msgSend + 20 1 UIKit 0x0005c970 -[UIView dealloc] + 60 2 UIKit 0x0005c840 -[UIImageView dealloc] + 76 3 CoreFoundation 0x0003963a -[NSObject release] + 28 4 MyApplication 0x000046a6 0x1000 + 13990 5 UIKit 0x00069750 -[UIViewController view] + 44 6 MyApplication 0x000053fa 0x1000 + 17402 The crash is made using 2 successive releases on an object. Thanks in advance.

  • [android] Is it possible to receive SMS message on appWidget?

    - by cappuccino
    [Android] Hi, everyone. Is it possible to receive SMS message on appWidget? I saw android sample soucrce(API Demos). In API Demos, ExampleAppWidgetProvider class extends AppWidgetProvider, not Activity. So, I guess it is impossible to regist SMS Receiver like this, rcvIncoming = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { Log.i("telephony", "SMS received"); Bundle data = intent.getExtras(); if (data != null) { // SMS uses a data format known as a PDU Object pdus[] = (Object[]) data.get("pdus"); String message = "New message:\n"; String sender = null; for (Object pdu : pdus) { SmsMessage part = SmsMessage.createFromPdu((byte[])pdu); message += part.getDisplayMessageBody(); if (sender == null) { sender = part.getDisplayOriginatingAddress(); } } Log.i(sender, message); } } }; registerReceiver(rcvIncoming, new IntentFilter("android.provider.Telephony.SMS_RECEIVED")); My goal is to receive SMS message on my custom appWidget. any help would be appreciated!!

  • WPF deployment strategy dilemma.clickonce(limited customization)+autoupdate vs installer(unlimited c

    - by black sensei
    Hello Experts!!! I've been facing a deployment problem.I've built a WPF application with visual studio 2008 and created an installer(msi) which works fine.But then it's pain to add automatic update to it. i've seen this article at windowsclient.net but it seems to be pretty old but could have been the perfect thing for me.Then i looked at the .Net Application updater block v2.0 which uses enterprise library june 2005 and for some reason it's not installing on my machine. I thought i will need to use a more recent Enterprise library so i installed and compiled Enterprise 4.1(october 2008) but nothing better happened.To i decided to give a try to CLickonce deployment.After struggling with it, it was almost perfect.I realized that when i was testing the updates provided by the clickonce on my machine which is XP i didn't notice the need of having sqlite dll in the GAC. surely it was already there.I noticed it when i moved to vista that there is a problem.After checking the net i know it's impossible to add a dll to the Global Assembly Cache. Now i'm stuck, i think i've hit a wall.Can any one share some of his experience? I'm willing to try the updater block if i can get help. Thanks for reading this!!

  • Adding multiple rss feeds to a script in SCALA InfoChannel Designer 5

    - by godleuf
    Okay, since it is impossible to talk to anyone on the phone or get support through Scala's "forum", I am going to take a shot and see if anyone out there is feeling my pain. I have a client that uses Scala's InfoChannel Designer and Content Manager. I have had to learn this software from scratch and I have to say it hasn't been easy. I think I am at a point where the overall design is set, but I need to implement a couple of things before I can make this happen. RSS feeds are my issue at this point. Multiple RSS feeds to be specific. I need a feed coming in for 3 areas of content: Wiki News (or equivalent), local weather and a stock ticker. I have learned how to setup a "crawl" using a script example available from Scala's file center and copying and pasting into my design. But from what I have learned first hand and through reading through other forums, you can not have a feed from 3 different sources or urls happening simultaneously. Doesn't seem like it would be an issue, but apparently it is. This small step has held up this project for far too long and I need to get it figured out. This doesn't even touch on my issue of feeding in streaming video as a background but I have gone over this in another question but with no luck thus far. If there is ANYONE out there who is in anything similar using this software, your feedback and/or suggestions would be greatly appreciated. Thanks you for allowing me to vent!

  • Lazy Sequences that "Look Ahead" for Project Euler Problem 14

    - by ivar
    I'm trying to solve Project Euler Problem 14 in a lazy way. Unfortunately, I may be trying to do the impossible: create a lazy sequence that is both lazy, yet also somehow 'looks ahead' for values it hasn't computed yet. The non-lazy version I wrote to test correctness was: (defn chain-length [num] (loop [len 1 n num] (cond (= n 1) len (odd? n) (recur (inc len) (+ 1 (* 3 n))) true (recur (inc len) (/ n 2))))) Which works, but is really slow. Of course I could memoize that: (def memoized-chain (memoize (fn [n] (cond (= n 1) 1 (odd? n) (+ 1 (memoized-chain (+ 1 (* 3 n)))) true (+ 1 (memoized-chain (/ n 2))))))) However, what I really wanted to do was scratch my itch for understanding the limits of lazy sequences, and write a function like this: (def lazy-chain (letfn [(chain [n] (lazy-seq (cons (if (odd? n) (+ 1 (nth lazy-chain (dec (+ 1 (* 3 n))))) (+ 1 (nth lazy-chain (dec (/ n 2))))) (chain (+ n 1)))))] (chain 1))) Pulling elements from this will cause a stack overflow for n2, which is understandable if you think about why it needs to look 'into the future' at n=3 to know the value of the tenth element in the lazy list because (+ 1 (* 3 n)) = 10. Since lazy lists have much less overhead than memoization, I would like to know if this kind of thing is possible somehow via even more delayed evaluation or queuing?

  • C# connect to domain SQL Server 2005 from non-domain machine

    - by user304582
    Hi, I asked a question a few days ago (http://stackoverflow.com/questions/2795723/access-to-sql-server-2005-from-a-non-domain-machine-using-windows-authentication) which got some interesting, but not usable suggestions. I'd like to ask the question again, but make clear what my constraints are: I have a Windows domain within which a machine is running SQL Server 2005 and which is configured to support only Windows authentication. I would like to run a C# client application on a machine on the same network, but which is NOT on the domain, and access a database on the SQL Server 2005 instance. I CANNOT create or modify OS or SQL Server users on either machine, and I CANNOT make any changes to permissions or impersonation, and I CANNOT make use of runas. I know that I can write Perl and Java applications that can connect to the SQL Server database using only these four parameters: server name, database name, username (in the form domain\user), and password. In C# I have tried various things around: string connectionString = "Data Source=server;Initial Catalog=database;User Id=domain\user;Password=password"; SqlConnection connection = new SqlConnection(connectionString); connection.Open(); and tried setting integrated security to true and false, but nothing seems to work. Is what I am trying to do simply impossible in C#? Thanks for any help, Martin

  • pluto or jetspeed on google app engine?

    - by Patrick Cornelissen
    I am trying to build something "portlet server"-ish on the google app engine. (as open source) I'd like to use the JSR168/286 standards, but I think that the restrictions of the app engine will make it somewhere between tricky and impossible. Has anyone tried to run jetspeed or an application that uses pluto internally on the google app engine? Based on my current knowledge of portlets and the google app engine I'm anticipating these problems: A war file with portlets is from the deployment standpoint more or less a complete webapp (yes, I know that it doesn't really work without a portal server). The war file may contain it's own web.xml etc. This makes deployment on the app engine rather difficult, because the apps are not visible to each other, so all portlet containing archives need to be included in the war file of the deployed "app engine based portal server". The "portlets" are (at least in liferay) started as permanent servlet processes, based on their portlet.xmls and web.xmls which is located in the same spot for every portlet archive that is loaded. I think this may be problematic in the app engine, because everything is in one big "web app", so it may be tricky to access the portlet.xmls from each archive. This prevents a 100% compatibility in my opinion. Is here anyone who has any experience with the combination of portlets and the app engine? Do you think it's feasible to modify jetspeed, pluto or any other portlet container to be able to run it on the app engine?

  • How to rename goals in Maven?

    - by mjs
    In the Maven document Introduction to the Build Lifecycle, a goal of display:time is described that outputs the current time. The plugin is as follows: ... <plugin> <groupId>com.mycompany.example</groupId> <artifactId>maven-touch-plugin</artifactId> <version>1.0</version> <executions> <execution> <phase>process-test-resources</phase> <goals> <goal>timestamp</goal> </goals> </execution> </executions> </plugin> ... I have several questions relating to this plugin: How can I change the name of the goal to, for example, foo:bar? (Why does neither display nor time appear anywhere in the XML fragment? How can you tell, from looking at the fragment, what goals it defines?) How can I manually run this goal? (For similar constructs, the equivalent of mvn display:time sometimes works, but this doesn't work consistently.) How can I see if this goal exists? (i.e. list available goals; this question suggests this is impossible.)

    When signing in to stackoverflow with google I get this message Stackoverflow.com is asking for some information from your Google Account [email protected] • Email address: [email protected] However on my site I can log in with openid but I can't ask for the email address. I get this message You are signing in to example.com with your Google Account [email protected] Also I'm finding it hard to know at what step I need to ask for it, here's some code where I think that step should be built into. /** * Authenticates the given OpenId identity. * Defined by Zend_Auth_Adapter_Interface. * * @throws Zend_Auth_Adapter_Exception If answering the authentication query is impossible * @return Zend_Auth_Result */ public function authenticate() { $id = $this->_id; $consumer = new Auth_OpenID_Consumer($this->_storage); if (!empty($id)) { $authRequest = $consumer->begin($id); if (is_null($authRequest)) { return new Zend_Auth_Result( Zend_Auth_Result::FAILURE, $id, array("Authentication failed", 'Unknown error')); } if (Auth_OpenID::isFailure($authRequest)) { return new Zend_Auth_Result( Zend_Auth_Result::FAILURE, $id, array("Authentication failed", "Could not redirect to server: " . $authRequest->message)); } $redirectUrl = $authRequest->redirectUrl($this->_root, $this->_returnTo); if (Auth_OpenID::isFailure($redirectUrl)) { return new Zend_Auth_Result( Zend_Auth_Result::FAILURE, $id, array("Authentication failed", $redirectUrl->message)); } Zend_OpenId::redirect($redirectUrl); } else { $response = $consumer->complete(Zend_OpenId::selfUrl()); switch($response->status) { case Auth_OpenID_CANCEL: case Auth_OpenID_FAILURE: return new Zend_Auth_Result( Zend_Auth_Result::FAILURE, null, array("Authentication failed. " . @$response->message)); break; case Auth_OpenID_SUCCESS: return $this->_constructSuccessfulResult($response); break; } } } It seems like such an obvious thing but I'm having a hard time googling and combing through the code just to find this. Thanks!

  • Parse JSON into a ListView friendly output

    - by Thomas McDonald
    So I have this JSON, which then my activity retrieves to a string: {"popular": {"authors_last_month": [ { "url":"http://activeden.net/user/OXYLUS", "item":"OXYLUS", "sales":"1148", "image":"http://s3.envato.com/files/15599.jpg" }, { "url":"http://activeden.net/user/digitalscience", "item":"digitalscience", "sales":"681", "image":"http://s3.envato.com/files/232005.jpg" } { ... } ], "items_last_week": [ { "cost":"4.00", "thumbnail":"http://s3.envato.com/files/227943.jpg", "url":"http://activeden.net/item/christmas-decoration-balls/75682", "sales":"43", "item":"Christmas Decoration Balls", "rating":"3", "id":"75682" }, { "cost":"30.00", "thumbnail":"http://s3.envato.com/files/226221.jpg", "url":"http://activeden.net/item/xml-flip-book-as3/63869", "sales":"27", "item":"XML Flip Book / AS3", "rating":"5", "id":"63869" }, { ... }], "items_last_three_months": [ { "cost":"5.00", "thumbnail":"http://s3.envato.com/files/195638.jpg", "url":"http://activeden.net/item/image-logo-shiner-effect/55085", "sales":"641", "item":"image logo shiner effect", "rating":"5", "id":"55085" }, { "cost":"15.00", "thumbnail":"http://s3.envato.com/files/180749.png", "url":"http://activeden.net/item/banner-rotator-with-auto-delay-time/22243", "sales":"533", "item":"BANNER ROTATOR with Auto Delay Time", "rating":"5", "id":"22243"}, { ... }] } } It can be accessed here as well, although it because it's quite a long string, I've trimmed the above down to display what is needed. Basically, I want to be able to access the items from "items_last_week" and create a list of them - originally my plan was to have the 'thumbnail' on the left with the 'item' next to it, but from playing around with the SDK today it appears too difficult or impossible to achieve this, so I would be more than happy with just having the 'item' data from 'items_last_week' in the list. Coming from php I'm struggling to use any of the JSON libraries which are available to Java, as it appears to be much more than a line of code which I will need to deserialize (I think that's the right word) the JSON, and they all appear to require some form of additional class, apart from the JSONArray/JSONObject script I have which doesn't like the fact that items_last_week is nested (again, I think that's the JSON terminology) and takes an awful long time to run on the Android emulator. So, in effect, I need a (preferably simple) way to pass the items_last_week data to a ListView. I understand I will need a custom adapter which I can probably get my head around but I cannot understand, no matter how much of the day I've just spent trying to figure it out, how to access certain parts of a JSON string..
