  • Android: HTTPClient

    Hi, I was trying http-cleint tutorials from svn.apache.org. While running the application I am getting the following error in console.

  • Why is jQuery so widely adopted versus other Javascript frameworks?

    - by Andrew Moore
    I manage a group of programmers. I do value my employees opinion but lately we've been divided as to which framework to use on web projects. I personally favor MooTools, but some of my team seems to want to migrate to jQuery because it is more widely adopted. That by itself is not enough for me to allow a migration. I have used both jQuery and MooTools. This particular essay tends to reflect how I feel about both frameworks. jQuery is great for DOM Manipulation, but seem to be limited to helping you do that. Feature wise, both jQuery and MooTools allow for easy DOM Selection and Manipulation: // jQuery $('#someContainer div[class~=dialog]') .css('border', '2px solid red') .addClass('critical'); // MooTools $('#someContainer div[class~=dialog]') .setStyle('border', '2px solid red') .addClass('critical'); Both jQuery and MooTools allow for easy AJAX: // jQuery $('#someContainer div[class~=dialog]') .load('/DialogContent.html'); // MooTools (Using shorthand notation, you can also use Request.HTML) $('#someContainer div[class~=dialog]') .load('/DialogContent.html'); Both jQuery and MooTools allow for easy DOM Animation: // jQuery $('#someContainer div[class~=dialog]') .animate({opacity: 1}, 500); // MooTools (Using shorthand notation, you can also use Fx.Tween). $('#someContainer div[class~=dialog]') .set('tween', {duration: 500}) .tween('opacity', 1); jQuery offers the following extras: Large community of supporters Plugin Repository Integration with Microsoft's ASP.NET and VisualStudio Used by Microsoft, Google and others MooTools offers the following extras: Object Oriented Framework with Classic OOP emulation for JS Extended native objects Higher consistency between browsers for native functions support. More easy code reuse Used by The World Wide Web Consortium, Palm and others. Given that, it seems that MooTools does everything jQuery does and more (some things I cannot do in jQuery and I can in MooTools) but jQuery has a smaller learning curve. So the question is, why did you or your team choose jQuery over another JavaScript framework? Note: While I know and admit jQuery is a great framework, there are other options around and I'm trying to take a decision as to why jQuery should be our choice versus what we use right now (MooTools)?

  • Delicious API and Yahoo oAuth in .NET

    - by Khash
    The fact that Delicious has two sets of API authentications one with username and password and one with oAuth told me something about things I was going to experience and I wasn't wrong. Unfortunately I have to deal with both APIs now and am unsuccessful getting through the first hurdle of API v2 (Yahoo oAuth). Here is a code snippet (I'm using OpenSocial in this example http://code.google.com/p/opensocial-net-client) public static string GetRequestToken(string callbackUrl) { string normaluri; string normaluriparam; OAuthBase oAuth = new OAuthBase(); string nonce = oAuth.GenerateNonce(); string timeStamp = oAuth.GenerateTimeStamp(); string sig = oAuth.GenerateSignature(new Uri(TOKEN_URL), ConfigurationManager.AppSettings[CONSUMER_KEY], ConfigurationManager.AppSettings[SECRET_KEY], string.Empty, string.Empty, "GET", timeStamp, nonce, OAuthBase.SignatureTypes.HMACSHA1, out normaluri, out normaluriparam); sig = HttpUtility.UrlEncode(sig); string result = HttpClient.Get(TOKEN_URL, new { oauth_nonce = nonce, oauth_timestamp = timeStamp, oauth_consumer_key = ConfigurationManager.AppSettings[CONSUMER_KEY], oauth_signature_method = "HMAC-SHA1", oauth_signature = sig, oauth_version = "1.0", oauth_callback = callbackUrl }); return result; } It seems it doesn't matter if I follow instructions at http://delicious.com/help/oauthapi myself of leave it to OpenSocial, I get an "401 Unauthorized" from the server with no further info. I can see many people have the same issue but couldn't find any resolution.

  • again about JPA/Hibernate bulk(batch) insert

    - by abovesun
    Here is simple example I've created after reading several topics about jpa bulk inserts, I have 2 persistent objects User, and Site. One user could have many site, so we have one to many relations here. Suppose I want to create user and create/link several sites to user account. Here is how code looks like, considering my willing to use bulk insert for Site objects. User user = new User("John Doe"); user.getSites().add(new Site("google.com", user)); user.getSites().add(new Site("yahoo.com", user)); EntityTransaction tx = entityManager.getTransaction(); tx.begin(); entityManager.persist(user); tx.commit(); But when I run this code (I'm using hibernate as jpa implementation provider) I see following sql output: Hibernate: insert into User (id, name) values (null, ?) Hibernate: call identity() Hibernate: insert into Site (id, url, user_id) values (null, ?, ?) Hibernate: call identity() Hibernate: insert into Site (id, url, user_id) values (null, ?, ?) Hibernate: call identity() So, I means "real" bulk insert not works or I am confused? Here is source code for this example project, this is maven project so you have only download and run mvn install to check output.

  • Howto rotate image using jquery rotate plugin?

    - by Tom
    How do you rotate an image using jquery (www.jquery.com) rotate plugin (http://code.google.com/p/jquery-rotate/)? I have tried the following and it doesn't seem to work: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> <title>View Photo</title> <script type="text/javascript" src="scripts/jquery.js"></script> <script type="text/javascript" src="scripts/jquery.rotate.1-1.js"></script> <script type="text/javascript"> var angle = 0; setInterval ( function (e) { rotate(); }, 100 ); function rotate() { angle = angle + 1; $('#pic').rotate(angle); } </script> </head> <body> <img border="0" src="player.gif" name="pic" id="pic"> </body> </html> Other methods that are supported by most browsers are wanted too, thanks!

  • NSTextField autocomplete

    - by Rasmus Styrk
    Does anyone know of any class or lib that can implement autocompletion to an NSTextField? I'am trying to get the standard autocmpletion to work but it is made as a synchronous api. I get my autocompletion words via an api call over the internet. What have i done so far is: - (void)controlTextDidChange:(NSNotification *)obj { if([obj object] == self.searchField) { [self.spinner startAnimation:nil]; [self.wordcompletionStore completeString:self.searchField.stringValue]; if(self.doingAutocomplete) return; else { self.doingAutocomplete = YES; [[[obj userInfo] objectForKey:@"NSFieldEditor"] complete:nil]; } } } When my store is done, i have a delegate that gets called: - (void) completionStore:(WordcompletionStore *)store didFinishWithWords:(NSArray *)arrayOfWords { [self.spinner stopAnimation:nil]; self.completions = arrayOfWords; self.doingAutocomplete = NO; } The code that returns the completion list to the nstextfield is: - (NSArray *)control:(NSControl *)control textView:(NSTextView *)textView completions:(NSArray *)words forPartialWordRange:(NSRange)charRange indexOfSelectedItem:(NSInteger *)index { *index = -1; return self.completions; } My problem is that this will always be 1 request behind and the completion list only shows on every 2nd char the user inputs. I have tried searching google and SO like a mad man but i cant seem to find any solutions.. Any help is much appreciated.

  • I/O error(socket error): [Errno 111] Connection refused

    - by Schitti
    I have a program that uses urllib to periodically fetch a url, and I see intermittent errors like : I/O error(socket error): [Errno 111] Connection refused. It works 90% of the time, but the othe r10% it fails. If retry the fetch immediately after it fails, it succeeds. I'm unable to figure out why this is so. I tried to see if any ports are available, and they are. Any debugging ideas? For additional info, the stack trace is: File "/usr/lib/python2.6/urllib.py", line 235, in retrieve fp = self.open(url, data) File "/usr/lib/python2.6/urllib.py", line 203, in open return getattr(self, name)(url) File "/usr/lib/python2.6/urllib.py", line 342, in open_http h.endheaders() File "/usr/lib/python2.6/httplib.py", line 868, in endheaders self._send_output() File "/usr/lib/python2.6/httplib.py", line 740, in _send_output self.send(msg) File "/usr/lib/python2.6/httplib.py", line 699, in send self.connect() File "/usr/lib/python2.6/httplib.py", line 683, in connect self.timeout) File "/usr/lib/python2.6/socket.py", line 512, in create_connection raise error, msg Edit - A google search isn't very helpful, what I got out of it is that the server I'm fetching from sometimes refuses connections, how can I verify its not a bug in my code and this is indeed the case?

  • How to change the border color of a Grouped UITableView

    - by ctpenrose
    This concerns iPhoneOS-sdk-3.2 I am having difficulty changing the border color of a grouped UITableView. I can change the cell background color, separator color, text color, quite easily now, and the rounded corners clip correctly, even when highlighted with whatever colors I have chosen. However the surrounding border remains infuriatingly gray despite many different attempts. I have read all of the related posts I can find via Google, let alone stackoverflow. I have tried both a programmatic and xib-based solution and both provide the same results. I will share the programmatic version below: I have a UIViewController subclass rather than a UITableViewController subclass to act as a UITableView delegate -- I chose this route as I am coding on the iPad and UITableViewController reportedly takes over the whole screen. loadView method of my UIViewController subclass: - (void) loadView { self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; [self.view release]; self.view.backgroundColor = [UIColor blackColor]; // add and configure UITableView CGRect tableViewRect = CGRectMake(0., 0., 256., 768.); myTableView = [[UITableView alloc] initWithFrame:tableViewRect style:UITableViewStyleGrouped]; // set the tableview delegate to this object and the datasource to the datasource which has already been set myTableView.delegate = self; myTableView.dataSource = self; myTableView.sectionIndexMinimumDisplayRowCount=1; myTableView.backgroundColor = [UIColor clearColor]; myTableView.separatorColor = [UIColor whiteColor]; myTableView.separatorStyle = UITableViewCellSeparatorStyleSingleLine; myTableView.opaque = NO; // add the table view to our background view [self.view addSubview:myTableView]; [myTableView release]; }

  • ajax redirect dillema, how to get redirect URL OR how to set properties for redirect request

    - by Anthony
    First, I'm working in Google Chrome, if that helps. Here is the behavior: I send an xhr request via jquery to a remote site (this is a chrome Extension, and I've set all of the cross-site settings...): $.ajax({ type: "POST", contentType : "text/xml", url: some_url, data: some_xml, username: user, password: pass, success: function(data,status,xhr){ alert(data); }, error: function(xhr, status, error){ alert(xhr.status); } }); The URL that is being set returns a 302 (this is expected), and Chrome follows the redirect (also expected). The new URL returns a prompt for credentials, which are not being pulled from the original request, so Chrome shows a login dialog. If I put in the original credentials, I get back a response about invalid request sent (it's a valid HTTP request -- 200 -- the remote server just doesn't like one of the headers). When viewing the developer window in Chrome, there are two requests sent. The first is to the original URL with all settings set in the ajax request. The second is to the redirect URL, with a method of "GET", nothing from the "POST" field, and no credentials. I am at a loss as to what I can do. I either need to: Get the redirect URL so I can send a second request (xhr.getResponseHeader("Location") does NOT work), Have the new redirect request preserver the settings from the original request, or Get the final URL that the error came from so I can send another request. Ideally I don't want the user to have to put in their credentials a second time in this dialog box, but I'll take what I can get if I can just get the final URL.

  • GWT carousel widget

    - by Nils
    Hello, I'm currently working on a GWT project, in which I need to use a "carousel" widget. The carousel widget is supposed to display pieces of information and 2 arrows - when the user clicks on one of the arrow, the content is moved with an animation and replaced with new content. I've been looking through the available widget libs, but the "carousel" widget does not seem to be that available. The only real candidate I found is the gwt-yui-carousel widget (see link below), but this seems to be an overload of ressources - though it does almost exactly what I need, but instead of displaying simple images, I'll have to display, in MVP terms, a view/presenter. Here is the widget running : http://gwt-yui-carousel.googlecode.com/svn/trunk/www/com.gwtyuicarousel.javascriptload.JavaScriptLoad/javascriptload.html (coming from here : http://code.google.com/p/gwt-yui-carousel/ ). Is there a better carousel widget available that I would not know of ? Or should I extend an existing one to create the desired effect ? Would you recommend to use the gwt-yui-carousel (I don't think so) ? If there is no better option, do you think that it would be a good idea to create the widget myself ? Note that I think that the key thing is, here, that I'll have to display presenter/views, which will fetch data in DataBase on arrow clicks and so on - so a customisation of an existing widget would be required, or the chosen widget should be able to display a list of GWT Widgets. Again I don't think that I can use one of the existing usual carousel widgets, since those are not "gwt-oriented" and could not support view/presenters and all this gwt stuff ;) Any answer would be greatly appreciated :) Best regards, Nils

  • AppEngine JRuby - OutOfMemoryError: Java heap space - can it be solved?

    - by elado
    I use AppEngine JRuby on Rails (SDK version 1.3.3.1) - a problem I encounter often is that after a few requests the server is getting really SLOW, until it dies and throws OutOfMemoryError on the terminal (OSX). The requests themselves are very lightweight, not more than looking for an entity or saving it, using DataMapper. On appspot, this problem is not happening. Is there any way to enlarge the heap space for JRuby? The exception log: Exception in thread "Timer-2" java.lang.OutOfMemoryError: Java heap space Apr 29, 2010 8:08:22 AM com.google.apphosting.utils.jetty.JettyLogger warn WARNING: Error for /users/close_users java.lang.OutOfMemoryError: Java heap space at org.jruby.RubyHash.internalPut(RubyHash.java:480) at org.jruby.RubyHash.internalPut(RubyHash.java:461) at org.jruby.RubyHash.fastASet(RubyHash.java:837) at org.jruby.RubyArray.makeHash(RubyArray.java:2998) at org.jruby.RubyArray.makeHash(RubyArray.java:2992) at org.jruby.RubyArray.op_diff(RubyArray.java:3103) at org.jruby.RubyArray$i_method_1_0$RUBYINVOKER$op_diff.call(org/jruby/RubyArray$i_method_1_0$RUBYINVOKER$op_diff.gen) at org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:146) at org.jruby.ast.CallOneArgNode.interpret(CallOneArgNode.java:57) at org.jruby.ast.LocalAsgnNode.interpret(LocalAsgnNode.java:123) at org.jruby.ast.NewlineNode.interpret(NewlineNode.java:104) at org.jruby.ast.BlockNode.interpret(BlockNode.java:71) at org.jruby.runtime.InterpretedBlock.evalBlockBody(InterpretedBlock.java:373) at org.jruby.runtime.InterpretedBlock.yield(InterpretedBlock.java:346) at org.jruby.runtime.InterpretedBlock.yield(InterpretedBlock.java:303) at org.jruby.runtime.Block.yield(Block.java:194) at org.jruby.RubyArray.collect(RubyArray.java:2354) at org.jruby.RubyArray$i_method_0_0$RUBYFRAMEDINVOKER$collect.call(org/jruby/RubyArray$i_method_0_0$RUBYFRAMEDINVOKER$collect.gen) at org.jruby.runtime.callsite.CachingCallSite.callBlock(CachingCallSite.java:115) at org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:122) at org.jruby.ast.CallNoArgBlockNode.interpret(CallNoArgBlockNode.java:64) at org.jruby.ast.CallNoArgNode.interpret(CallNoArgNode.java:61) at org.jruby.ast.LocalAsgnNode.interpret(LocalAsgnNode.java:123) at org.jruby.ast.NewlineNode.interpret(NewlineNode.java:104) at org.jruby.ast.BlockNode.interpret(BlockNode.java:71) at org.jruby.ast.EnsureNode.interpret(EnsureNode.java:98) at org.jruby.ast.BeginNode.interpret(BeginNode.java:83) at org.jruby.ast.NewlineNode.interpret(NewlineNode.java:104) at org.jruby.ast.BlockNode.interpret(BlockNode.java:71) at org.jruby.ast.EnsureNode.interpret(EnsureNode.java:96) at org.jruby.internal.runtime.methods.InterpretedMethod.call(InterpretedMethod.java:201) at org.jruby.internal.runtime.methods.DefaultMethod.call(DefaultMethod.java:183)

  • OAuthWebSecurity.VerifyAuthentication IsSuccessful returns false how do I to determine the reason?

    - by Eonasdan
    I'm using DotNetOpenAuth with a MVC 4 application. All the sudden Google auth is failing (MS is working). The stock code does this: [AllowAnonymous] public ActionResult ExternalLoginCallback(string returnUrl) { var result = OAuthWebSecurity.VerifyAuthentication(Url.Action("ExternalLoginCallback", new { ReturnUrl = returnUrl })); if (!result.IsSuccessful) { return RedirectToAction("ExternalLoginFailure"); } I know that result.IsSuccessful is false, but how do I get the reason? result.Error is null.

  • iPhone/iPod receive messages from C# tcpip server using CocoaAsyncSocket

    - by SorinA.
    Hello, i'm trying to send/receive data over wifi to an iphone/ipodtouch app from a C# tcpip server. for this i used cocoaAsyncSocket from the google project. If i push a button and i send a request from ipod to server it returns the requested data(song title for example)..i want to know every second what song is playng...so from C# server i send at intervals of 1 second messages to my app. In my app in an timer with the interval of 1 second i call the asyncSocket read readDataWithTimeout method. My problem is that after 8-9 seconds that method is not called anymore. The connection to the server is still active and the C# server still sends data.. what i want to do is the following thing: - winamp plays a song - C# server asks winamp what songs is he playing and sends the song title to my app. - iphone app receives the data and displays it i don't know why the readDataWithTimeout method is not called anymore after a short period of time..Maybe because the short time between messages sent by the C# server? Thank you, Sorin

  • Display Simple Web Page In My Application Using Blackberry BrowserField

    - by ankit
    Hello All, What I am trying to do is display a simple web page in my application (no javascript,cookies or any scripting and not trying to detect any events such as mouse click etc.). I am using the code below and right now all I get is empty screen .. I know that the application is accessing the internet (the data transfer arrow flashes in the top right corner) but not sure why its not rendering. The code I am using is : HttpConnectionFactory factory = new HttpConnectionFactory("www.google.ca",HttpConnectionFactory.TRANSPORT_WIFI | HttpConnectionFactory.TRANSPORT_WAP2 | HttpConnectionFactory.TRANSPORT_DIRECT_TCP); while(true) { try { HttpConnection connection = factory.getNextConnection(); try { BrowserContent bc = RenderingSession.getNewInstance().getBrowserContent(connection,null,0); Field f = bc.getDisplayableContent(); add(f); } catch(RenderingException e) { //Log the error or store it for displaying to //the end user if no transports succeed System.out.println("error with rendering page"); } } catch(NoMoreTransportsException e) { //There are no more transports to attempt //Dialog.alert( "Unable to perform request" ); //Note you should never //attempt network activity on the event thread System.out.println("no more transport"); break; } } Some points to note: Im using the http-connection-factory class from www.versatilemonkey.com only becuase they have impelemented the abstract httpConnection class. If someone can also point me on how to implement my own that would be great. I am using '0' for the flags for getBrowserContent function. I looked through the rimn documentation and could not find an explanation for them. Any help would be greatly appreciated. Thanks, ankit

  • "Hello, WebView" tutorial opens the requested address in Android browser and not in my webview

    - by VitalyB
    Hi everyone, I am using Android emulator with AVD of Android 2.1 and I have the following problem: Trying to load a URL in a WebView using webView.loadUrl causes it to open in the browser instead. Note: I am talking about the initial opening, not the issue in which links from the WebView open in a browser, though, perhaps it is somehow connected. I've tried several things: I've removed <uses-permission android:name="android.permission.INTERNET" /> from the manifest. That actually made it work correctly, i.e, load the html into the webview. However, as one would expect, the only thing it loaded is "unable to connect the internet" error page. I've tried downloading a real sample project ("Hello Android" book source files, project - BrowserView). However, it didn't work just the same. I've created a new project and followed the directions at Google's official tutorial of using WebView and got the same result. I haven't find anyone else complaining about it. Why does it happen? Thanks, Vitaly

  • Using android.view.SurfaceView with a camera on part of the screen

    - by oneself
    Hi, I trying to put together an Android app that will take a picture and process it in some way. I'd like the layout to be similar to Google Goggles. Meaning, camera preview on the top, and some controls on the bottom using portrait orientation. I've built a first version using code sample from here. This works, but I want to add a button on the bottom. I've modified my main.xml to look as follows: <?xml version="1.0" encoding="utf-8"?> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="150dp" android:stretchColumns="1"> <TableRow> <android.view.SurfaceView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/preview" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </TableRow> <Button android:id="@+id/snap" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Snap" /> <TableRow> </TableRow> </TableLayout> But when I run this code I get an exception: java.lang.RuntimeException: startPreview failed. When I replace the SurfaceView above with something else, e.g. a TextView, that it displays, but in landscape. How can I get a camera preview on part of the screen using portrait view? Thanks

    Hi, I want to control the x and y axis of a multi series line charts available in Silverlight toolkit from the C# code. I am not able to find any appropriate example using google. Any kind of example or pointers would be appreciated! EDIT: This is what I have done so far: <toolkit:Chart Canvas.Left="104" Canvas.Top="18" Name="chartCompare" Title="Compare Series" Height="285" Width="892"> <toolkit:LineSeries Title="SP1" Name="Series1"/> </toolkit:Chart> And in the code behind I am trying this: Series1.ItemsSource = ObjectList; Series1.IndependentValuePath = "Val1"; Series1.DependentValuePath = "Val2"; Where ObjectList is a List of Objects which has val1 and val2 as its property. But it is throwing an error when I run this in Line "Series1.ItemsSource = ObjectList;" saying "Object reference not set to an instance of an object..". I have initialised and set its value just in the line before it. Actually I have set this as an item source for a data grid in the line before it and it works fine.

  • kanban scrumish tool(s) to get started

    - by Davide
    After investigating a little bit scrum and kanban, I finally read this answer and decided to start using kanban, picking something from scrum (note that I'm working mostly by myself, and I do have read this question and its answers). Now, my question is: which tool would be best to get started? whiteboard and postit agilezen.com JIRA with greenhopper a spreadsheet (possibly on Google Docs) brightgreenprojects.com Agilo Target Process something else (please specify) Notes about each: I would lean towards the whiteboard, but there are several drawbacks (e.g. cannot make automatic charts, time measurements, metrics, and sometimes I work from home - where I need it most - and it's not convenient to carry :-) I don't want to remember another username/password (I promised to myself to signup only to OpenID-enabled services) My employer has JIRA but my group doesn't use it - I might ask for an account (it shouldn't require another password) and maybe later involve the rest of the group. But I don't know if they are using greenhopper and if it's a big deal installing it. I generally hate spreadsheets maybe overkill? I'd be happy to have a localhost instance, but it could be problematic to give access to the whole group (per network/firewalls) - not a deal-breaker but surely a concern What I'd like to get from this? being more productive tracking how much time I spend in any given task, possibly discussing the issue with my supervisor tracking what "blocks" me most often immediately see where I am compared to my schedule manage in a better way my long todo list (e.g. answering faster to the "what I should do next?" question) Do you have any suggestion? Note on the scrumish tag: read the Henrik Kniberg's PDF. He first introduced the definition of scrumish on page 9.

  • Find the "largest" dense sub matrix in a large sparse matrix

    - by BCS
    Given a large sparse matrix (say 10k+ by 1M+) I need to find a subset, not necessarily continuous, of the rows and columns that form a dense matrix (all non-zero elements). I want this sub matrix to be as large as possible (not the largest sum, but the largest number of elements) within some aspect ratio constraints. Are there any known exact or aproxamate solutions to this problem? A quick scan on Google seems to give a lot of close-but-not-exactly results. What terms should I be looking for? edit: Just to clarify; the sub matrix need not be continuous. In fact the row and column order is completely arbitrary so adjacency is completely irrelevant. A thought based on Chad Okere's idea Order the rows from largest count to smallest count (not necessary but might help perf) Select two rows that have a "large" overlap Add all other rows that won't reduce the overlap Record that set Add whatever row reduces the overlap by the least Repeat at #3 until the result gets to small Start over at #2 with a different starting pair Continue until you decide the result is good enough

  • feedparser - various errors

    - by Eiriks
    I need feedparser (se http://www.feedparser.org) for a project, and want to keep third party modules in a separate folder. I did this by adding a folder to my python path, and putting relevant modules there, among them feedparser. This first attempt to import feedparser resulted in import feedparser Traceback (most recent call last): File "", line 1, in File "/home/users/me/modules/feedparser.py", line 1 ed socket timeout; added support for chardet library ^ SyntaxError: invalid syntax I found the text "socket timeout; added..." in the comments at the bottom of the file, removed these comments, and tried again: import feedparser Traceback (most recent call last): File "", line 1, in File "/home/users/me/modules/feedparser.py", line 1 = [(key, value) for key, value in attrs if key in self.acceptable_attributes] ^ IndentationError: unexpected indent Ok, so some indent error. I made sure the indent in the function in question where ok (moved some line breaks down to no-indent). And tried again: import feedparser Traceback (most recent call last): File "", line 1, in File "/home/users/me/modules/feedparser.py", line 1 , value) for key, value in attrs if key in self.acceptable_attributes] ^ SyntaxError: invalid syntax As much I google, I cannot find anything wrong with the syntax: def unknown_starttag(self, tag, attrs): if not tag in self.acceptable_elements: if tag in self.unacceptable_elements_with_end_tag: self.unacceptablestack += 1 return attrs = self.normalize_attrs(attrs) attrs = [(key, value) for key, value in attrs if key in self.acceptable_attributes] _BaseHTMLProcessor.unknown_starttag(self, tag, attrs) Now what? Is my approach all wrong? Why do I keep producing these errors in a module that seems so well tested and trusted?

  • How to programmatically start a WPF application from a unit test?

    - by Lernkurve
    Problem VS2010 and TFS2010 support creating so-called Coded UI Tests. All the demos I have found, start with the WPF application already running in the background when the Coded UI Test begins or the EXE is started using the absolute path to it. I, however, would like to start my WPF application under test from the unit test code. That way it'll also work on the build server and on my peer's working copies. How do I accomplish that? My discoveries so far a) This post shows how to start a XAML window. But that's not what I want. I want to start the App.xaml because it contains XAML resources and there is application logic in the code behind file. b) The second screenshot on this post shows a line starting with ApplicationUnterTest calculatorWindow = ApplicationUnderTest.Launch(...); which is conceptually pretty much what I am looking for, except that again this example uses an absolute path the the executable file. c) A Google search for "Programmatically start WPF" didn't help either.

  • prototype.js equivalent to jquery ajaxSettings cache = true addthis plugin

    - by openstepmedia
    I need help from a prototype.js expert: I'm trying to achieve the following (taken from the addthis forum), and port the solution from jquery to prototype.js (I'm using magento). Original post is here: http://www.addthis.com/forum/viewtopic.php?f=3&t=22217 For the getScript() function, I can create a custom function to load the remote js, however I'm trying to load the js file via the prototype ajax call, and trying to avoid having the script cached in the browser. <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> $(document).ready(function() { $("#changeURL").click(function() { $(".addthis_button").attr("addthis:url","http://www.example.com"); window.addthis.ost = 0; window.addthis.ready(); }); }); // prevent jQuery from appending cache busting string to the end of the URL var cache = jQuery.ajaxSettings.cache; jQuery.ajaxSettings.cache = true; jQuery.getScript('http://s7.addthis.com/js/250/addthis_widget.js'); // Restore jQuery caching setting jQuery.ajaxSettings.cache = cache; </script> <p id="changeURL">Change URL</p> <a class="addthis_button" addthis:url="http://www.google.com"></a> <script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#username=rahf"></script>

  • UINavigationController inside tabbar loading a child root view

    - by Doug
    Hi guys, Firstly i'll preface by saying that i am a complete Cocoa touch/objective c noob (.Net dev having a dabble) I have searched on Google as well as here but cannot seem to find an easy solution. I have a UItabbarcontroller view with a UINavigationController inside its first tab I have the root view for this UINavigationController stored in a seperate class and NIB as i am trying to seperate the data viewing from the data loading (i'm going to reuse the table list in multiple places in my database) and simply pass the root view its data using a loading method and have it take it from there. What i want to happen: App loads and loads the first view of the tab bar (A UINavigationController) The UINavigationController inside the first view loads a root view (a UIViewController with a table view) and sets its title The UINavigationController loads the data from a web service and parses it The UINavigationController sends the data to a loading method inside the UIViewController Am i thinking about this completely wrongly? What currently happens: the first tab bar loads with an empty uinavigationcontroller (no table view) the data methods fire and get the webservice data this child view gets sent its data using the loading method the tableview delegate events fail to fire inside the child view telling it to load the data into the table I just can't seem how to load my second view inside the root view of the navigation controller and then send it my data?
