• Can someone explain me implicit parameters in Scala?

  - by Oscar Reyes

  And more specifically how does the BigInt works for convert int to BigInt? In the source code it reads: ... implicit def int2bigInt(i: Int): BigInt = apply(i) ... How is this code invoked? I can understand how this other sample: "Date literals" works. In. val christmas = 24 Dec 2010 Defined by: implicit def dateLiterals(date: Int) = new { import java.util.Date def Dec(year: Int) = new Date(year, 11, date) } When int get's passed the message Dec with an int as parameter, the system looks for another method that can handle the request, in this case Dec(year:Int) Q1. Am I right in my understanding of Date literals? Q2. How does it apply to BigInt? Thanks

• How to create a Java String from the contents of a file

  - by Oscar Reyes

  I've been using this idiom for some time now. And it seems to be the most wide spread at least in the sites I've visited. Does anyone have a better/different way to read a file into a string in Java. Thanks private String readFile( String file ) throws IOException { BufferedReader reader = new BufferedReader( new FileReader (file)); String line = null; StringBuilder stringBuilder = new StringBuilder(); String ls = System.getProperty("line.separator"); while( ( line = reader.readLine() ) != null ) { stringBuilder.append( line ); stringBuilder.append( ls ); } return stringBuilder.toString(); }

• How do I nested options for plugins in jQuery

  - by Oscar Godson

  I know how to do plugins, but how do I do nested options like: var defaults = { spacing:10, shorten_to:50, from_start:0, from_end:2, classes: { test:'testing' } }; i know that isn't right, i just dont know how to write the proper syntax when I want to do something like this: $('#breadcrumbs').breadcrumbs({classes{test:'new_example'},spacing:12}) other suggestions are welcome, im in need of the ability to custom class names and there are 7, so rather than making something like test_class, example_class, etc id like it cleaner and neater like the example above.

• IE8 is subtracting wrong in JavaScript / jQuery?

  - by Oscar Godson

  In every browser, Win/Mac, Chrome, Safari, Firefox, Opera, IE6, and IE7 they ALL get the following console output: 352 254 But in IE8 I get: 414 434 454 474 Here is my JS/jQuery code: $('#top-breadcrumbs').children('a').each(function(i){ if(!$(this).hasClass('permanent')){ if(permItemWidth+rmItemWidth > $('#top-breadcrumbs').width()){ $(this).addClass('removed'); rmItemWidth = rmItemWidth-$(this).width()+20; } } }); The log code i have above is writing the NEW rmItemWidth value after its been reset in that 2nd if

• Resizing a UIButton programmatically by maintaining a margin

  - by Oscar Del Ben

  Hello, I'm adding a UIButton to a tableView footer programmatically. This button has a left and right margin that is equal to the tableView margin: UIButton *deleteButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; deleteButton.frame = CGRectMake(10, 60, 300, 34); deleteButton.autoresizingMask = UIViewAutoresizingFlexibleWidth I'm adding autoresizingMask because I want to support rotation. However, it does not work as I want, as the button stretches all the way down to the right, as shown by the image below. Any idea how to fix it? If I remove the autosizing property then the margin is correct.

• Change the content type of a pop up window.

  - by Oscar Reyes

  This question brought a new one: I have a html page and I need it to change the content type when the user press "save" button so the browser prompt to save the file to disk I've been doing this in the server side to offer "excel" versions of the page ( which is basically a html table ) <c:if test="${page.asExcelAction}"> <% response.setContentType("application/vnd.ms-excel"); %> What I'm trying to do now is to do the same, but in the client side with javacript but I can't manage to do it so. This is what I've got so far: <html> <head> <script> function saveAs(){ var sMarkup = document.getElementById('content').innerHTML; //var oNewDoc = document.open('application/vnd.ms-excel'); var oNewDoc = document.open('text/html'); oNewDoc.write( sMarkup ); oNewDoc.close(); } </script> </head> <body> <div id='content'> <table> <tr> <td>Stack</td> <td>Overflow</td> </tr> </table> </div> <input type="button" value="Save as" onClick="saveAs()"/> </body> </html>

• How to select the first property with unknown name and first item from array in JSON

  - by Oscar Godson

  I actually have two questions, both are probably simple, but for some odd reason I cant figure it out... I've worked with JSON 100s of times before too! but here is the JSON in question: {"69256":{ "streaminfo":{ "stream_ID":"1025", "sourceowner_ID":"2", "sourceowner_avatar":"http:\/\/content.nozzlmedia.com\/images\/sourceowner_avatar2.jpg", "sourceownertype_ID":"1", "stream_name":"Twitter", "streamtype":"Social media" "appsarray":[] }, "item":{ "headline":"Charboy", "main_image":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg", "summary":"ate a tomato and avocado for dinner...", "nozzl_captured":"2010-05-12 23:02:12", "geoarray":[{ "state":"OR", "county":"Multnomah", "city":"Portland", "neighborhood":"Downtown", "zip":"97205", "street":"462 SW 11th Ave", "latitude":"45.5219", "longitude":"-122.682" }], "full_content":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.", "body_text":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.", "author_name":"Charboy", "author_avatar":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg", "fulltext_url":"http:\/\/twitter.com\/charboy\/statuses\/13889868936", "leftovers":{ "twitter_id":"tag:search.twitter.com,2005:13889868936", "date":"2010-05-13T02:59:59Z", "location":"iPhone: 45.521866,-122.682262" }, "wordarray":{ "0":"ate", "1":"tomato", "2":"avocado", "3":"dinner", "4":"tonight", "5":"tasty", "6":"foods", "7":"just", "8":"enjoyable", "9":"Charboy", "11":"Twitter", "13":"state:OR", "14":"county:Multnomah, OR", "15":"city:Portland, OR", "16":"neighborhood:Downtown", "17":"zip:97205" } } } } Question 1: How do I loop through each item (69256) when the number is random? e.g. item 1 is 123, item2 is 646? Like, for example, a normal JSON feed would have something like: {'item':{'blah':'lorem'},'item':{'blah':'ipsum'}} the JS would be like console.log(item.blah) to return lorem then ipsum in a loop How do I do it when i dont know the first item of the object? Question 2: How do I select items from the geoarray object? I tried: json.test.item.geoarray.latitude and json.test.item.geoarray['latitude']

• keyDown works but i get beeps

  I just got my keydown method to work. But i get system beep everytime i press key. i have no idea whats wrong.

• Custom Date Format with jax-rs in apache cxf?

  - by Oscar Chan

  Hi, I have been googling to figure out how I can customize the Date format when I use jax-rs on apache CXF. I looked at the codes, and it seems that it only support primitives, enum and a special hack that assume the type associated with @ForumParam has a constructor with a single string parameter. This force me to use String instead of Date if I want to use ForumParam. it is kind of ugly. Is there a better way to do it? @POST @Path("/xxx") public String addPackage(@FormParam("startDate") Date startDate) { ... } Thanks

• Attaching an event to an Iframe that contains more iframes

  - by Oscar Godson

  I have an editor which is in my window that contains a wrapping iframe and then 2 more iframes inside like (the HTML inside the <iframe> element is inserted via write() in JS, not hardcoded like this): <iframe class="parent"> <div class="wrapper"> <iframe class="editor"></iframe> <iframe class="previewer"></iframe> </div> </iframe> One is an editor, the other is a previewer. The first one that contains the two (we'll call this the parent) has an eventListener for mousemove attached to it, but nothing is firing. If i add a 5px border for example, the event will fire when I move my mouse on the border of the parent, but not when i hover over the middle which contains the editor or previewer (previewer is display:none while the editor is visible, and vice versa). So, the blue area in the following i can mousemove, but the rest I can't. It's most likely because of the stacking order, but how can I attach an event to fire on the entire frame? I need mousemove because on mousemove I display a menu in the bottom right. I want the same menu to display whether or not the editor or the previewer is visible.

• My cocoa app won't capture key events

  Hi, i usually develop for iPhone. But now trying to make a pong game in Cocoa desktop application. Working out pretty well, but i can't find a way to capture key events. Here's my code: #import "PongAppDelegate.h" #define GameStateRunning 1 #define GameStatePause 2 #define BallSpeedX 10 #define BallSpeedY 15 @implementation PongAppDelegate @synthesize window, leftPaddle, rightPaddle, ball; - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { gameState = GameStateRunning; ballVelocity = CGPointMake(BallSpeedX, BallSpeedY); [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(gameLoop) userInfo:nil repeats:YES]; } - (void)gameLoop { if(gameState == GameStateRunning) { [ball setFrameOrigin:CGPointMake(ball.frame.origin.x + ballVelocity.x, ball.frame.origin.y + ballVelocity.y)]; if(ball.frame.origin.x + 15 > window.frame.size.width || ball.frame.origin.x < 0) { ballVelocity.x =- ballVelocity.x; } if(ball.frame.origin.y + 35 > window.frame.size.height || ball.frame.origin.y < 0) { ballVelocity.y =- ballVelocity.y; } } } - (void)keyDown:(NSEvent *)theEvent { NSLog(@"habba"); // Arrow keys are associated with the numeric keypad if ([theEvent modifierFlags] & NSNumericPadKeyMask) { [window interpretKeyEvents:[NSArray arrayWithObject:theEvent]]; } else { [window keyDown:theEvent]; } } - (void)dealloc { [ball release]; [rightPaddle release]; [leftPaddle release]; [super dealloc]; } @end

• Alternative to WhitePages API?

  - by Oscar Godson

  I'm using the WhitePages API ( developer.whitepages.com ) to get a phone type (landline or cellular) and the phone's service provider (Verizon, T-Mobile, etc), but they only have a personal API which limits you to 2 calls a second and/or 1,500 calls a day. The paid version, or "Pro", is a minimum of $500 a month and/or $0.10 a call. Does anyone know another service where I can get that information for free or cheaper than $500 / $0.10 a call? If not I'll have to try to cache everything and it'll technically be against their TOS...

• Why am I having this InstantiationException in Java when accessing final local variables?

  - by Oscar Reyes

  I was playing with some code to make a "closure like" construct ( not working btw ) Everything looked fine but when I tried to access a final local variable in the code, the exception InstantiationException is thrown. If I remove the access to the local variable either by removing it altogether or by making it class attribute instead, no exception happens. The doc says: InstantiationException Thrown when an application tries to create an instance of a class using the newInstance method in class Class, but the specified class object cannot be instantiated. The instantiation can fail for a variety of reasons including but not limited to: - the class object represents an abstract class, an interface, an array class, a primitive type, or void - the class has no nullary constructor What other reason could have caused this problem? Here's the code. comment/uncomment the class attribute / local variable to see the effect (lines:5 and 10 ). import javax.swing.*; import java.awt.event.*; import java.awt.*; class InstantiationExceptionDemo { //static JTextField field = new JTextField();// works if uncommented public static void main( String [] args ) { JFrame frame = new JFrame(); JButton button = new JButton("Click"); final JTextField field = new JTextField();// fails if uncommented button.addActionListener( new _(){{ System.out.println("click " + field.getText()); }}); frame.add( field ); frame.add( button, BorderLayout.SOUTH ); frame.pack();frame.setVisible( true ); } } class _ implements ActionListener { public void actionPerformed( ActionEvent e ){ try { this.getClass().newInstance(); } catch( InstantiationException ie ){ throw new RuntimeException( ie ); } catch( IllegalAccessException ie ){ throw new RuntimeException( ie ); } } } Is this a bug in Java? edit Oh, I forgot, the stacktrace ( when thrown ) is: Caused by: java.lang.InstantiationException: InstantiationExceptionDemo$1 at java.lang.Class.newInstance0(Class.java:340) at java.lang.Class.newInstance(Class.java:308) at _.actionPerformed(InstantiationExceptionDemo.java:25)

• Cocoa Key event problem

  - by Oscar

  I'm trying to build my first cocoa application. done some iPhone developing before. I have a hard time understanding how to layout my project. i making a Pong game and my current design is to allocate an NSWindowController from my appDelegate. I then use custom view to act as paddles and ball. My problem is that i can't get the window controller to capture key events. Am i thinking wrong here? My idea is to have a controller class with all the logic, should i subclass another class for that?

• Regex with dynamic <textarea>

  - by Oscar Godson

  How can I do this with the JS replace() method: Make \n\n change to <p>$1</p> Change single \n to <br> Then back again. I think I have this part, see the JS at the bottom. Example HTML: <p>Hello</p><p>Wor<br>ld</p> The <textarea> would look like: Hello Wor ld So, how can I achieve this? It's an AJAX form where when you click on this div it changes to a <textarea> and back, and fourth, etc. So, I need to it to go from <p>s and <br>s to \n\n and \n. For the going to <textarea> from HTML I have: $(this).html().replace(/\s?<\/?(p|br\s?\/?)>\s?/g,"\n")

• Porting some PHP to ColdFusion

  - by Oscar Godson

  OK, I'm working with converting some very basic PHP to port to a dev server where the client only has CF. Ive never worked with it, and I just need to know how to port a couple things: <?php $pageTitle = 'The City That Works'; $mainCSSURL = 'header_url=../images/banner-home.jpg&amp;second_color=484848&amp;primary_color=333&amp;link_color=09c&amp;sidebar_color=f2f2f2'; require('includes/header-inc.php'); ?> I know: <cfinclude template="includes/header-inc.cfm"> but how to i get the var to be passed to the include and then how do I use it on the subsequent included file? Also in my CSS (main.php) I have (at the top): <?php header('Content-type: text/css'); foreach($_GET as $css_property => $css_value) {define(strtoupper($css_property),$css_value);} ?> and im using those constants like this: #main-content a {color:#<?= LINK_COLOR ?>;} How can I get that to work also with CF? Never thought I'd be working with CF :)

• iPhone - dismiss multiple ViewControllers

  - by Oscar Peli

  Hi there, I have a long View Controllers hierarchy; in the first View Controller I use this code: SecondViewController *svc = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; [self presentModalViewController:svc animated:YES]; [svc release]; In the second View Controller I use this code: ThirdViewController *tvc = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil]; [self presentModalViewController:tvc animated:YES]; [tvc release]; and so on. So there is a moment when I have many View Controllers and I need to come back to the first View Controller. If I come back one step at once, I use in every View Controller this code: [self dismissModalViewControllerAnimated:YES]; If I want to go back directly from the, say, sixth View Controller to the first one, what I have to do to dismiss all the Controllers at once? Thanks

• Closing InfoWindow with Google Maps API V3

  I've seen the other posts, but they dont have the markers being looped through dynamically like mine. How do I create an event that will close the infowindow when another marker is clicked on using the following code? $(function(){ var latlng = new google.maps.LatLng(45.522015,-122.683811); var settings = { zoom: 10, center: latlng, disableDefaultUI:false, mapTypeId: google.maps.MapTypeId.SATELLITE }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); $.getJSON('api',function(json){ for (var property in json) { if (json.hasOwnProperty(property)) { var json_data = json[property]; var the_marker = new google.maps.Marker({ title:json_data.item.headline, map:map, clickable:true, position:new google.maps.LatLng( parseFloat(json_data.item.geoarray[0].latitude), parseFloat(json_data.item.geoarray[0].longitude) ) }); function buildHandler(map, marker, content) { return function() { var infowindow = new google.maps.InfoWindow({ content: '<div class="marker"><h1>'+content.headline+'</h1><p>'+content.full_content+'</p></div>' }); infowindow.open(map, marker); }; } new google.maps.event.addListener(the_marker, 'click',buildHandler(map, the_marker, {'headline':json_data.item.headline,'full_content':json_data.item.full_content})); } } }); });
