  • Unable to establish the connection to the file in BlackBerry

    - by Vikas
    I have tried the example code on SO to read the contents from the file in the resource directory in BlackBerry. But I am having an issue with the FileConnection. I get the following error: File system error (1003) I tried the example from here. I want only the read functionality, the file I want to read is in CSV format as a .txt file placed in the /res/test.txt. public class FileDemo extends MainScreen { public FileDemo() { setTitle("My Page"); String str = readTextFile("file:///test.txt"); System.out.println("Contents of the file::::::: " + str); } public String readTextFile(String fName) { String result = null; FileConnection fconn = null; DataInputStream is = null; try { fconn = (FileConnection) Connector.openInputStream(fName); is = fconn.openDataInputStream(); byte[] data = IOUtilities.streamToBytes(is); result = new String(data); } catch (IOException e) { System.out.println(e.getMessage()); } finally { try { if (null != is) is.close(); if (null != fconn) fconn.close(); } catch (IOException e) { System.out.println(e.getMessage()); } } return result; } } Any suggestions/advice on a better approach or as to how I can get this working??

  • Simple javascript/jquery append, remove question

    - by Scarface
    Hey guys, quick question. I have a div that on click will execute a jquery function onclick, and then replace the div with its opposite div which onclick will replace back to the first div just like the favorite function on this site. I am having a simple problem I hope someone can spot or explain to me it is not possible. The function works with the initial two divs that are served directly, but when I click on either of the original two divs, and the function executes and replaces the div with the corresponding div the replacement div does not execute the function. I have to refresh the page to get the original div, which is identical to execute the function. Is the div actually replaced on the page with append, or does it just visually show it? Any advice appreciated. original div <div class="unfavorite"><img id="unfavorite_img" src="images/favorite2.png" /></div> javascript div replacement $(".favorite").remove(); $(".favoriteholder").append('<div class="unfavorite"><img id="unfavorite_img" src="images/favorite2.png" /></div>');

  • How to select "child" entities in subview?

    - by Andy
    I am trying to manage a drill-down list of data. I've got an entity, Contact, that has a to-many relationship with another entity, Rule. In my root view controller, I use a fetched results controller to manage and display the list of Contacts. When a Contact is tapped, I push a new view controller onto the stack with a list of the Contact's Rules. I have not been able to figure out how to use a second fetched results controller to display the Rules, so I'm using the following: // create a set of the contact's rules rules = [NSMutableSet set]; rules = [self.contact mutableSetValueForKey:@"rule"]; // create an array of rules from the set arrayOfRules = [NSMutableArray arrayWithCapacity:[rules count]]; for (id oneObject in rules) [arrayOfRules addObject:oneObject]; // sort the array of rules NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"phoneLabel" ascending:YES]; [arrayOfRules sortUsingDescriptors:[NSArray arrayWithObject:descriptor]]; [descriptor release]; I create a set of Rules, then use that to create an array of Rules for sorting. I then use these two collections to populate the grouped table view. All of this appears to be working correctly. Here's my problem: There are several different actions a user can take in this view, and most of them require that I know which Rule was tapped. But I can't figure out how to get that. For instance, say a user wants to delete a Rule. It seems to me the proper approach is something like... [rules removeObject:ruleObjectToBeRemoved] ...but I can't figure out how to specifiy ruleObjectToBeRemoved. I hope all of this makes sense. As usual, thanks in advance for any advice you can offer.

  • Summary statistics in visual basic

    - by ben
    Below I am trying to write a script the goal of which is to calculate some summary statistics for a few different columns of numbers. I have gotten some help on it up to the "Need help below" mark. But beyond that I am flabergasted as to how to calculate the simple stats (sum, mean, standard deviation, coefficient of variation).

  • Navigation Controller with Tab Bar only on first view

    - by dinoc
    I am seeking advice on how to start my project. I need to use a combination of the navigation controller and tabbar controller but on the second screen, I need the tabbar controller not to be there. Here is a brief description of the two main screens Screen 1 will have a tabbar controller with two tabs. The first tab is a tableview and when you tap on a table cell, it drills down to Screen 2. The second tab is just a filter view that updates the table in the first tab of Screen 1. Screen two is just a details screen from the cells of Screen 1. The catch is that I don't want the TabBar on Screen 2. I am struggling with how to get started. Do I start with a Navigation-based application since I need to be able to drill down? How do I just add a tab bar to the main screen of the navigation based app? I can't start with a Tab Bar application because if I load a navigation controller inside one of the views of the tab controller, then when I drill down inside the nav controller, the tab bar still stays on the next screen when I need it to go away. Any help would be appreciated.

  • DynamicContent.html: Write a JavaScript in an HTML document that can change the content of an HTML e

    - by A sw A
    ShowHide.html: Write a JavaScript in an HTML document that displays an image and allows the user to toggle the image between appearing and not appearing in the document. Place your image in a (division) tag that has a style attribute. “style.visibility” can take two values: “visible” and “hidden”. The document has a button called “Toggle Image”, which calls the toggle function upon the event “onclick”. DynamicColors.html: Write a JavaScript in an HTML document that changes the background and foreground colors of the body of a document according to the user input. The document has two input texts: background color and foreground color. The colors change when the event “onchange” occurs as you type in the text input and the event handler is called. Your event handler takes two parameters: “where”, and “newColor”. To change the document color and background color you need to change the elements document.body.style.color and document.body.style.backgroundColor. Available colors are: black, silver, gray, white, maroon, red, purple, fuchsia, green, lime, olive, yellow, navy, blue, teal, and aqua. DynamicContent.html: Write a JavaScript in an HTML document that can change the content of an HTML element (a help box). The content of an element is accessed through its “value” property. The content of a help box can change depending on the placement of the mouse cursor. When the cursor is placed over a particular input field (“onmouseover” event), the help box can display advice on how the field is to be filled. When the cursor is moved away from the input field (“onmouseout” event), the help box content changes to simply indicate that assistance is available. Your messages are stored in an array of strings.

  • Should I be backing up a webapp's data to another host continuously ?

    - by user196289
    I have webapp in development. I need to plan for what happens if the host goes down. I will lose some very recent session status (which I can live with) and everything else should be persistently stored in the database. If I am starting up again after an outage, can I expect a good host to reconstruct the database to within minutes of where I was up to ? Or seconds ? Or should I build in a background process to continually mirror the database elsewhere ? What is normal / sensible ? Obviously a good host will have RAID and other redundancy so the likelihood of total loss should be low, and if they have periodic backups I should lose only very recent stuff but this is presumably likely to be designed with almost static web content in mind, and my site is transactional with new data being filed continuously (with a customer expectation that I don't ever lose it). Any suggestions / advice ? Are there off the shelf frameworks for doing this ? (I'm primarily working in Java) And should I just plan to save the data or should I plan to have an alternative usable host implementation ready to launch in case the host doesn't come back up in a suitable timeframe ?

  • What's a good way to organize a large collection of personal scripts using git?

    - by spooky note
    I have a large collection of my personal scripts that I would like to start versioning using Git. I've previously organized my code as follows: ~/code/python/projects/ (for large stuff, each project contained in an individual folder) ~/code/python/scripts/ (single file scripts all contained in this directory) ~/code/python/sandbox/ (my testing area) ~/code/python/docs/ (downloaded documentation) ~/code/java/... (as above) Now i'm going to start versioning my code using git, so that I can have history and backup all my code to a remote server. I know if I were using SVN I would just keep my entire "~/code/" directory in a large repository, but I understand this is not a good way to do things with Git. Most info I've seen online suggests keeping all my project folders in a single place (as in, no separate directories for python or java) with each project containing it's own git repository, and simply having a "snippets" directory containing all single-file scripts/experiments that can be converted into projects at a later date. But I'm not sure how I feel about consolidating all of my code directories into one area. Is there a good way to keep my separate code directories intact, or is it not worth the effort? Maybe I'm just attached to the separate code directories because I've never known anything else... Also (as a side note), I'd like to quickly be able to see a chronological history of all my projects and scripts. So I can see which projects I created most recently. I used to do this by keeping a number at the beginning of all my projects, 002project, 003project. Is there automatic or easy way to do this in git without having to add a number to all of the project names? I'm open to any practical or philosophical code organizing advice you have. Thanks!!!

  • How can I get 100% test coverage in a Perl module that uses DBI?

    - by BrianH
    I am a bit new to the Devel::Cover module, but have found it very useful in making sure I am not missing tests. A problem I am running into is understanding the report from Devel::Cover. I've looked at the documentation, but can't figure out what I need to test to get 100% coverage. Here is the output from the cover report: line err stmt bran cond sub pod time code ... 36 sub connect_database { 37 3 3 1 1126 my $self = shift; 38 3 100 24 if ( !$self->{dsn} ) { 39 1 7 croak 'dsn not supplied - cannot connect'; 40 } 41 *** 2 33 21 $self->{dbh} = DBI->connect( $self->{dsn}, q{}, q{} ) 42 || croak "$DBI::errstr"; 43 1 11 return $self; 44 } ... line err % l !l&&r !l&&!r expr ----- --- ------ ------ ------ ------ ---- 41 *** 33 1 0 0 'DBI'->connect($$self{'dsn'}, '', '') || croak("$DBI::errstr") And here is and example of my code that tests this specific line: my $database = MyModule::Database->new( { dsn => 'Invalid DSN' }); throws_ok( sub { $database->connect_database() }, qr/Can't connect to data source/, 'Test connection exception (invalid dsn)' ); This test passes - the connect does throw an error and fulfills my "throws_ok" test. I do have some tests that test for a successful connection, which is why I think I have 33% coverage, but if I'm reading it correctly, cover thinks I am not testing the "|| croak" part of the statement. I thought I was, with the "throws_ok" test, but obviously I am missing something. Does anyone have advice on how I can test my DBI-connect line successfully? Thanks!

  • Cannot connect to mysql via servlet

    - by JBoy
    Hi all I have been since 2 days trying to figure out why my servlet does not connect to the database MySql. I have mysql installed and working properly and eclipse. Whenever i try to etabilish a connection i get the ClassNotFoundException for the com.mysql.jdbc.Driver, which is actually properly imported, the connector i'm using is the mysql-connector-java5.1.14 added properly as external jar so everything seems fine. here's my code protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String dbUrl="jdbc:mysql://localhost:3306/test"; String username="root"; String password=""; try { Class.forName("com.mysql.jdbc.Driver").newInstance(); conn=DriverManager.getConnection(dbUrl); System.out.println("Connected!"); } catch (SQLException e) { e.printStackTrace(); System.out.println("not connected"); } catch(ClassNotFoundException x){ x.printStackTrace(); } catch(Exception e){ e.printStackTrace(); } } The stacktrace(part of): java.lang.ClassNotFoundException: com.mysql.jdbc.Driver at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1645) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1491) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:375) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:164) i'm following the connection steps from a published java book and also in forums and tutorials i just see the same code, cannot figure out why that Exception comes. On a normal application which does not run on the server the Exception isn't thrown and the connection (in the exact same way) its successfull. Do you have any advice?

  • Java - multithreaded access to a local value store which is periodically cleared

    - by Telax
    I'm hoping for some advice or suggestions on how best to handle multi threaded access to a value store. My local value storage is designed to hold onto objects which are currently in use. If the object is not in use then it is removed from the store. A value is pumped into my store via thread1, its entry into the store is announced to listeners, and the value is stored. Values coming in on thread1 will either be totally new values or updates for existing values. A timer is used to periodically remove any value from the store which is not currently in use and so all that remains of this value is its ID held locally by an intermediary. Now, an active element on thread2 may wake up and try to access a set of values by passing a set of value IDs which it knows about. Some values will be stored already (great) and some may not (sadface). Those values which are not already stored will be retrieved from an external source. My main issue is that items which have not already been stored and are currently being queried for may arrive in on thread1 before the query is complete. I'd like to try and avoid locking access to the store whilst a query is being made as it may take some time.

  • Should I be worried if I don't get any internships by 3rd year's end?

    - by karamba
    I am in some mediocre college in some corner of India. Am about to complete 3rd year C.S. in a month and a half. I have no idea how to go about "finding an internship" as everyone seems to put it. Looking at online advice, I find that a primary way is to "use your contacts". I am sad to say that I don't have many friends(those I have, I am trying to get help from them for all it's worth), and my family can't help me as they have no idea about the software industry. My college has no official facility for aiding students in this, and the few faculty members who had contacts in "whatever" part of the industry have favoured some students that they have personally come to know. (Though I hear that the "internships" they got involve them stocking equipment in some small companies.... still it's something?) I'm getting nervous. I am considering just spending the coming summer refining my skills in C++ and begin learning MySQL and C#, both of which I have zero experience in. Maybe work on my own project... like a library management system. Relative to those in my college, I think I am among the best programmers there, but that isn't saying much as a lot of students can barely write basic code. I have experience in teaching myself C++, and DirectX9 having created a Tetris clone, some basic 3D apps (bouncing balls), and a basic console-based, text-file-database-using library management system (which I plan to improve this summer). Is it alright if I spend my summer so? Will I be able to get a job later on? I know I have to improve my social skills to get anywhere in life, and I will try, but say I am stuck like this till 4th year's end... will such self studying, online learning help me in landing a decent job? Perhaps after I have learned a bit more, joining some open source project?

  • Upgraded Eclipse. Every app force closes

    - by user1309500
    I would be really grateful for some urgent advice:- I was merrily building my apps (using eclipse) for Android platform 2.2. Everything all working lovely and ready to upload to the marketplace. I thought I would try to install Google Play Licensing and in the process, I was told to download the LVL but that was not available in my SDK download list - and I read I had to updrage my SDK and ADT to the latest. So I did, I now have: ADT 17.0.0 along with ANDROID DDMS, hierarchy viewer and Traceview at 17.0.0 with Eclipse IDE 1.4.2 And I also upgraded my SDK Android 2.2 stuff to the latest. Now:- I have no errors in my app workplaces on Eclipse. But now when I run the apps, they build but force close straight away upon loading. This includes the app I was working on (and working perfectly before) and all the other apps I have ever made. Every app now force closes and I dont know what to do. Been up all night and was ready to upload them to the market place... :( Any help!? Thanks! Please!

  • What is the best Networking implementation for my application?

    - by CaptainPhil
    I am in the planning phases of a project for myself, it is to be a single and multi-player card game. I would like to track statistics for each person such as world rankings etc... My problem is I do not know the best approach for the client - server architecture and programming. My original goal was to program everything in C# as I want to get proficient in that language. My original idea was to have a back-end database and a back end server run on some sort of hosting on the internet, however that seems costly for such a small project that may or may not make any money. I have tried looking into cloud services however I am unfamiliar with the technology, and I am not sure I can make them suit my needs, especially since most like Google's cloud wants you to use their coding architecture from what I understand. Finally my last problem is that I would like an architecture that can be used for different languages so that I can port it from PC to IPhone, Xbox etc... So does anyone have any advice on the best architecture and language to do this in? Am I worrying about architecture and back-end costs to much and should just concentrate on getting the game running any which way?

  • Android - How to approach fall detection algorithm

    - by bobby123
    I want to be able to feature a fairly simple fall detection algorithm in my application. At the moment in onSensorChanged(), I am getting the absolute value of the current x,x,z values and subtracting SensorManager.GRAVITY_EARTH (9.8 m/s) from this. The resulting value has to be bigger than a threshold value 10 times in a row to set a flag saying a fall has been detected by the accelerometer, the threshold value is about 8m/s. Also I'm comparing the orientation of the phone as soon as the threshold has been passed and the orienation of it when the threshold is no longer being passed, this sets another flag saying the orientation sensor has detected a fall. When both flags are set, an event occurs to check is user ok, etc etc. My problem is with the threshold, when the phone is held straight up the absolute value of accelerometer is about 9.8 m/s, but when i hold it still at an angle it can be over 15m/s. This is causing other events to trigger the fall detection, and if i increase the threshold to avoid that, it won't detect falls. Can anyone give me some advice here with what possible values i should use or how to even improve my method? Many thanks.

  • A scheme to show picture

    - by luoliyong
    I have a requirement that need me to show picture using one canvas. All the operation will be done on this canvas, include change the picture (This picture is made of lines, rectangular and so on. Draw these lines or rectangular will use the base method). In China, we called use double buffer(CGBitmapContextCreate), one of the scheme like this // create the bitmap context CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(nil,27,27,8,0, colorSpace,kCGImageAlphaPremultipliedLast); CFRelease(colorSpace); Maybe now it is not very clear. I talk about the project. The project has an engine, That will call methed draw line, draw round ,draw rectangular according user's input, this lines, rounds, rectangular will make up a picture? and then usr changes his input, the picture also will change, the engine accept usr's input, and draw picture. and the engine inits only once. I hope you can understand what I say, and give me some advice. Thanks.

  • STLifying C++ classes

    - by shambulator
    I'm trying to write a class which contains several std::vectors as data members, and provides a subset of vector's interface to access them: class Mesh { public: private: std::vector<Vector3> positions; std::vector<Vector3> normals; // Several other members along the same lines }; The main thing you can do with a mesh is add positions, normals and other stuff to it. In order to allow an STL-like way of accessing a Mesh (add from arrays, other containers, etc.), I'm toying with the idea of adding methods like this: public: template<class InIter> void AddNormals(InIter first, InIter last); Problem is, from what I understand of templates, these methods will have to be defined in the header file (seems to make sense; without a concrete iterator type, the compiler doesn't know how to generate object code for the obvious implementation of this method). Is this actually a problem? My gut reaction is not to go around sticking huge chunks of code in header files, but my C++ is a little rusty with not much STL experience outside toy examples, and I'm not sure what "acceptable" C++ coding practice is on this. Is there a better way to expose this functionality while retaining an STL-like generic programming flavour? One way would be something like this: (end list) class RestrictedVector<T> { public: RestrictedVector(std::vector<T> wrapped) : wrapped(wrapped) {} template <class InIter> void Add(InIter first, InIter last) { std::copy(first, last, std::back_insert_iterator(wrapped)); } private: std::vector<T> wrapped; }; and then expose instances of these on Mesh instead, but that's starting to reek a little of overengineering :P Any advice is greatly appreciated!

  • android service using SystemClock.elapsedRealTime() instead of SystemClock.uptimeMillis() works in emulator but not in samsung captivate ?

    - by Aleadam
    First question here in stackoverflow :) I'm running a little android 2.2 app to log cpu frequency usage. It is set up as a service that will write the data every 10 seconds using a new thread. The code for that part is very basic (see below). It works fine, except that it would not keep track of time while the phone is asleep (which, I know, is the expected behavior). Thus, I changed the code to use SystemClock.elapsedRealTime() instead. Problem is, in emulator both commands are equivalent, but in the phone the app will start the thread but it will never execute the mHandler.postAtTime command. Any advice regarding why this is happening or how to overcome the issue is greatly appreciated. PS: stopLog() is not being called. That's not the problem. mUpdateTimeTask = new Runnable() { public void run() { long millis = SystemClock.uptimeMillis() - mStartTime; int seconds = (int) (millis / 1000); int minutes = seconds / 60; seconds = seconds % 60; String freq = readCPU (); if (freq == null) Toast.makeText(CPU_log_Service.this, "CPU frequency is unreadable.\nPlease make sure the file has read rights.", Toast.LENGTH_LONG).show(); String str = new String ((minutes*60 + seconds) + ", " + freq + "\n"); if (!writeLog (str)) stopLog(); mHandler.postAtTime(this, mStartTime + (((minutes * 60) + seconds + 10) * 1000)); }}; mStartTime = SystemClock.uptimeMillis(); mHandler.removeCallbacks(mUpdateTimeTask); mHandler.postDelayed(mUpdateTimeTask, 100);

  • SLRequest return nil before block complete

    - by jaytr0n
    I'm having a little trouble thinking through this and deciding if it's a design flaw on my behalf or if I'm missing a piece that could make this work. Basically I'm using the new SLRequest to make a Twitter API call. After the data is returned, I'd like to put it into an object and return that object: -(AUDSlide *) getFollowerSlide { SLRequest *getRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:[NSURL URLWithString:[NSString stringWithFormat:@"https://api.twitter.com/1.1/followers/ids.json?user_id=%@", [[self.twitterAccount valueForKey:@"properties"] valueForKey:@"user_id"]]] parameters:nil]; getRequest.account = twitterAccount; AUDSlide *slide = [[AUDSlide alloc] init]; [getRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) { if ([urlResponse statusCode] == 200) { NSError *jsonError = nil; NSDictionary *list = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:&jsonError]; NSLog(@"Number of Followers: %u", [[list objectForKey:@"ids"] count]); slide.title = @"Followers"; slide.number = [NSString stringWithFormat:@"%u",[[list objectForKey:@"ids"] count]]; } else{ slide.title = @"Error"; slide.number = [NSString stringWithFormat: @"E%u", [urlResponse statusCode]]; } }]; return slide; } Of course the slide is returned before the call is complete and returns a nil object. So I'm not sure if I should try to force this into a synchronous request (that seems like it could be a bad idea) or rethink the design. Does anyone have any advice?

  • Disable a form and all contained elements until an ajax query completes (or another solution to prev

    - by Max Williams
    I have a search form with inputs and selects, and when any input/select is changed i run some js and then make an ajax query with jquery. I want to stop the user from making further changes to the form while the request is in progress, as at the moment they can initiate several remote searches at once, effectively causing a race between the different searches. It seems like the best solution to this is to prevent the user from interacting with the form while waiting for the request to come back. At the moment i'm doing this in the dumbest way possible by hiding the form before making the ajax query and then showing it again on success/error. This solves the problem but looks horrible and isn't really acceptable. Is there another, better way to prevent interaction with the form? To make things more complicated, to allow nice-looking selects, the user actually interacts with spans which have js hooked up to them to tie them to the actual, hidden, selects. So, even though the spans aren't inputs, they are contained in the form and represent the actual interactive elements of the form. Grateful for any advice - max. Here's what i'm doing now: function submitQuestionSearchForm(){ //bunch of irrelevant stuff var questionSearchForm = jQuery("#searchForm"); questionSearchForm.addClass("searching"); jQuery.ajax({ async: true, data: jQuery.param(questionSearchForm.serializeArray()), dataType: 'script', type: 'get', url: "/questions", success: function(msg){ //more irrelevant stuff questionSearchForm.removeClass("searching"); }, error: function(msg){ questionSearchForm.removeClass("searching"); } }); return true; }

  • How to write this loop prettier?

    - by Tom
    I've just read this topic http://stackoverflow.com/questions/2930533/highlight-search-keywords-on-hover and actually I use pretty the same structure, but it looks awful. So can you give me an advice, how to write this loop prettier in one php file, I mean php and html at the same time? <table class="result"> <?php while ($row= mysql_fetch_array($result, MYSQL_ASSOC)) { $cQuote = highlightWords(htmlspecialchars($row['cQuotes']), $search_result); ?> <tr> <td style="text-align:right; font-size:15px;"><?php h($row['cArabic']); ?></td> <td style="font-size:16px;"><?php echo $cQuote; ?></td> <td style="font-size:12px;"><?php h($row['vAuthor']); ?></td> <td style="font-size:12px; font-style:italic; text-align:right;"><?php h($row['vReference']); ?></td> </tr> <?php } ?>

  • HTML5 card game [closed]

    - by ChrisCa
    I created a card game in silverlight a year or so ago in order to learn a bit about Silverlight. I am now wanting to make a HTML5 version of the game in an effort to learn a little bit more about that. I am thinking I'd like to take advantage of stuff like Knockout.js and WebSockets and the canvas element. Now what I'm confused about is how to lay out the cards on the screen. With Silverlight I was able to make a "Hand" control, which was made up of two sub controls - the cards the player has in their hand and the ones they have on the table. And they in turn were made up of Card controls. Now I don't believe there is the concept on a User Control in javascript. So I am possibly thinking about this in entirely the wrong way. So my question is - how could I lay out some cards on the table and perhaps make reuse of something for each player? I have a client side JSON object called game, which contains an array of players. Each player has a hand which is made up of an array of in-hand cards and on-table cards. Ideally I would like to bind these to something using Knockout.js - but I don't know what I could bind to. Would I simply position images (of cards) on a canvas? Is there a way to make some kind of Hand object that each player could have and that I could bind to? Any advice? Or sample code you've seen elsewhere?
