  • [Python] Detect destination of shortened, or "tiny" url

    - by conradlee
    I have just scraped a bunch of Google Buzz data, and I want to know which Buzz posts reference the same news articles. The problem is that many of the links in these posts have been modified by URL shorteners, so it could be the case that many distinct shortened URLs actually all point to the same news article. Given that I have millions of posts, what is the most efficient way (preferably in python) for me to detect whether a url is a shortened URL (from any of the many URL shortening services, or at least the largest) Find the "destination" of the shortened url, i.e., the long, original version of the shortened URL. Does anyone know if the URL shorteners impose strict request rate limits? If I keep this down to 100/second (all coming form the same IP address), do you think I'll run into trouble?

  • Django: test failing on a view with @login_required

    - by Esteban Feldman
    Hi all, I'm trying to build a test for a view that's decorated with @login_required, since I failed to make it work, I did a simple test and still can't make it pass. Here is the code for the simple test and the view: def test_login(self): user = self._create_new_user() self.assertTrue(user.is_active) login = self.client.login(username=user.username, password=self.data['password1']) self.failUnless(login, 'Could not log in') response = self.client.get('/accounts/testlogin/') self.assertEqual(response.status_code, 200) @login_required def testlogin(request): print 'testlogin !! ' return HttpResponse('OK') _create_new_user() is saving the user and there is a test inside that method to see that is working. The test fails in the response.status_code, returning 302 and the response instance is of a HttpResponseRedirect, is redirecting it as if not logged in. Any clue? I'm missing something? Regards Esteban

  • unresolved external symbol __penter referenced in function _WspiapiStrdup@4

    I started getting this compile error after upgrading to Visual Studio 2010. Not sure if it's related, but I can't figure out what library to reference to satisfy this dependency?

  • Populating an association with children in factory_girl

    - by Craig Walker
    I have a model Foo that has_many 'Bar'. I have a factory_girl factory for each of these objects. The factory for Bar has an association to Foo; it will instantiate a Foo when it creates the Bar. I'd like a Factory that creates a Foo that contains a Bar. Ideally this Bar would be created through the :bar factory, and respect the build strategy (create/build) used to create the Foo. I know I could just call the :bar factory and then grab the Foo reference from the new Bar. I'd like to avoid this; in my test case, the important object is Foo; calling the Bar factory seems a bit circuitous. Also, I can see the need for a Foo with multiple Bars. Is this possible in factory_girl? How do you define this relationship in the parent?

  • Django/Python best practice template_dict

    - by fredrik
    Hi, After just been coding for about 6-9 months. I probably changed my coding style a number of times after reading some code or read best practices. But one thing I haven't yet come a cross is a good why to populate the template_dict. As of now I pass the template_dict across a number of methods (that changes/modifies it) and returns is. The result is that every methods takes template_dict as first argument and the returns it and this in my eyes doesn't seems to be the best solution. An idea is to have a method that handles all the changes. But I'm curios if there's a best practice for this? Or is it "do what you feel like"-type of thing? The 2 things I think is pretty ugly is to send as an argument and return it in all methods. And the just the var name is written xxx number of times in the code :) ..fredrik

  • How do i enable transactions

    - by acidzombie24
    I have a similar question of how to check if you are in a transaction. Instead of checking how do i allow nested transactions? I am using Microsoft SQL File Database with ADO.NET. I seen examples using tsql and examples starting transactions using begin and using transaction names. When calling connection.BeginTransaction i call another function pass in the same connection and it calls BeginTransaction again which gives me the exception SqlConnection does not support parallel transactions. It appears many microsoft variants allow this but i cant figure out how to do it with my .mdf file. How do i allow nested transactions with a Microsoft SQL File Database using C# and ADO.NET?

  • Xpath and parameters

    - by Daniel
    I am relatively new to XSL and I think this is a basic question. So I better get my apologies in early! Basically, I would like to use a value-of function. This will be in a template and I would like to pass part of the xpath as a parameter. <xsl:variable name="TEST_VAR">"h:elementA/elementB"</xsl:variable> ... and then use the variable (or passed in param) as all (or part) of the xpath: <xsl:element name="transformedElement"><xsl:value-of select=$TEST_VAR/></xsl:element> I would really like to have the xpath to be a mixture of string literals and the vlue of TEST_VAR. Thanks in advance

  • How to get ID of EditorFor with nested viewmodels in asp.net mvc 2

    - by Luke
    So I have two nested view models, CreditCard - BillAddress. I have a view, "EditBilling", that has EditorFor(CreditCard). The CreditCard EditorTemplate has EditorFor(BillAddress), and the BillAddress EditorTemplate has EditorFor(BillState). The end result is a select list with id "CreditCard_BillAddress_BillState". I need to reference this in javascript, thus need to know the ID. In other situations, with non-nested ViewModels, I have used the following code: $('#<%= ViewData.ModelMetadata.PropertyName %>_BillState') The problem here is that the ModelMetadata.PropertyName property is only aware of the current property, not the parent(s). So I end up with the following: $('#BillAddress_BillState') How does one go about getting the client ID of nested strongly typed helpers? Thanks in advance.

  • How can I make Rails 3 router to localize url's using localization files?

    - by edgerunner
    What I'd like to be able to do is: in config/routes.rb resources :posts in config/locale/en.yml en: resources: posts: "posts" new: "new" edit: "edit" in config/locale/tr.yml tr: resources: posts: "yazilar" new: "yeni" edit: "duzenle" and get I18n.locale = :en edit_post_path(3) #=> /posts/3/edit I18n.locale = :tr edit_post_path(3) #=> /yazilar/3/duzenle I'd also like rails to match any of these routes anytime and pass the associated locale in the params hash such that when I navigate to /yazilar , the request should be routed to the posts#index action. Any simple way of doing that?

  • Why will IIS 6 not serve my custom 404 page when I set the URL in 'Custom Errors'?

    - by Glenn Slaven
    I've got an ASP.NET MVC site & I've got an Errors controller with a NotFound action which works great for 404 errors that pass though .NET, but for stuff that doesn't (like static files) I've set the Custom Errors value for 404 to URL with a value of /Errors/NotFound. But when I do this & hit a non-existant page the site just gives me this: The system cannot find the path specified. Is this because it's a dynamic url, can IIS not redirect 404 requests to dynamic urls or have I screwed up the config somewhere?

  • Java annotations for design patterns?

    - by Greg Mattes
    Is there a project that maintains annotations for patterns? For example, when I write a builder, I want to mark it with @Builder. Annotating in this way immediately provides a clear idea of what the code implements. Also, the Javadoc of the @Builder annotation can reference explanations of the builder pattern. Furthermore, navigating from the Javadoc of a builder implementation to @Builder Javadoc is made easy by annotating @Builder with @Documented. I've being slowing accumulating a small set of such annotations for patterns and idioms that I have in my code, but I'd like to leverage a more complete existing project if it exists. If there is no such project, maybe I can share what I have by spinning it off to a separate pattern/idiom annotation project. Update: I've created the Pattern Notes project in response to this discussion. Contributions welcome! Here is @Builder

  • Copying data across tabs

    - by Guillermo
    Hello, I got two different forms in two different tabs. One has data from our system and the other one is an interface of another, external, system in wich we need to copy data into (XML or API integration not an option here) The this is that, having open both forms - in two different tabs - i need a greasemonkey script or something similar that allows my to copy data from one form to the other (using the getValue method in Javascript). The problem right now is that I cannot figure out how to reference with a greasemonkey script one particular tab or window (to rad data from or write data to). Do you think it would be possible to do what I'm thinking to do? THANKS

  • Spreadsheet ML Text Color (Colour) Rendering

    - by Chris Roberts
    Hi All, I am writing a tool which generates some Spreadsheet ML (XML) to create an Excel spreadsheet for my users. I have defined a style as follows: <Style ss:ID="GreenText"> <Font ss:FontName="Arial" ss:Size="9" ss:Color="#8CBE50" /> </Style> This works to an extent, but when I open it in Excel the colour rendered for the text isn't the one I specified - it's a brighter version. I can use the same colour reference for a cell border and the colour is rendered correctly. Can anyone shed any light on why the text colour isn't rendered correctly? Thanks!

  • Send HTTP Post with default browser with C#

    - by Paul
    Hello, I am wondering if it is possible to send POST data with the default browser of a computer in C#. Here is the situation. My client would like the ability to have their C# application open their browser and send client information to a webform. This webform would be behind a login screen. The assumption from the application side is that once the client data is sent to the login screen, the login screen would pass that information onto the webform to prepopulate it. This would be done over HTTPS and the client would like this to be done with a POST and not a GET as client information would be sent as plain text. I have found some wonderful solutions that do POSTS and handle the requests. As an example http://geekswithblogs.net/rakker/archive/2006/04/21/76044.aspx So the TL;DR version of this would be 1) Open Browser 2) Open some URL with POST data Thanks for your help, Paul

  • How can I return default at loop end in Scheme?

    - by Kufi Annan
    I'm trying to implement back-tracking search in Scheme. So far, I have the following: (define (backtrack n graph assignment) (cond (assignment-complete n assignment) (assignment) ) (define u (select-u graph assignment)) (define c 1) (define result 0) (let forLoop () (when (valid-choice graph assignment c) (hash-set! assignment u c) (set! result (backtrack n graph assignment)) (cond ((not (eq? result #f)) result)) (hash-remove! assignment u) ) (set! c (+ c 1)) (when (>= n c) (forLoop)) ) #f ) My functions assignment-complete and select-u pass unit tests. The argument assignment is a hash-table make with (make-hash), so it should be fine. I believe the problem I have is related to returning false at the end of the loop, if no recursive returns a non-false value (which should be a valid assignment).

  • C# equlivent of performSelectorOnMainThread

    - by jamone
    I haven't done much multithreading before and now find the need to do some background work and keep the UI responsive. I have the following code. data.ImportProgressChanged += new DataAccess.ImportDelegate(data_ImportProgressChanged); Thread importThread = new Thread( new ThreadStart(data.ImportPeopleFromFAD)); importThread.IsBackground = true; importThread.Start(); void data_ImportProgressChanged(int progress) { toolStripProgressBar.Value = progress; } //In my data object I have public void ImportPeopleFromFAD() { ImportProgressChanged(someInt); } But the UI doesn't get updated since the ImportProgressChanged() call is made on the background thread. In objective C I know you can use performSelectorOnMainThread and pass it a method to call using the main thread. What is the equivalent way of calling ImportProgressChanged() from the main thread?

  • How can I click a button behind a transparent UIView?

    - by Sean Clark Hess
    Let's say we have a view controller with one sub view. the subview takes up the center of the screen with 100 px margins on all sides. We then add a bunch of little stuff to click on inside that subview. We are only using the subview to take advantage of the new frame ( x=0, y=0 inside the subview is actually 100,100 in the parent view). Then, imagine that we have something behind the subview, like a menu. I want the user to be able to select any of the "little stuff" in the subview, but if there is nothing there, I want touches to pass through it (since the background is clear anyway) to the buttons behind it. How can I do this? It looks like touchesBegan goes through, but buttons don't work.

  • Connect sortable lists together and update SQL using jQuery UI

    - by rebellion
    I'm using jQuery UI's sortable lists to sort items in a todo list, and the reordering of the lists works like a charm. I have several UL lists for each todo category, i.e. Design, Development, etc. I want to be able to move an item from one category to another, and jQuery UI's sortable lists plugin allows me to do this with the connectWith option parameter. But I can't seem to find how to update the database as well. The todo database table has a field for a reference to the category which is laying in it's own table. This is the current code: $('.sortable').sortable({ axis: 'y', opacity: .5, cancel: '.no-tasks', connectWith: '.sortable', update: function(){ $.ajax({ type: 'POST', url: basepath + 'task/sort_list', data: $(this).sortable('serialize') }); } }); Do I need to add another value to the AJAX's data parameter, or do the sortable plugin this for me in the serialize function?

  • ASP.NET - Web Application, UserControls and NullReferenceExceptions

When I replace the register declaration with: <%@ Register TagPrefix="mine" Namespace="MyAssembly.UserControls" Assembly="MyAssembly"%> I get a null reference exception in the UserControl's Page_Load event (which references an ASP.NET control which is used by the UserControl itself. I find this pretty bizarre, but I've found very little information on how to fix it.

  • How do we read the data from a public google spreadsheet using Zend_Gdata

    - by bobo
    I have read the examples here: http://framework.zend.com/manual/en/zend.gdata.spreadsheets.html But those examples assume the spreadsheet to be read needs authentication: $service = Zend_Gdata_Spreadsheets::AUTH_SERVICE_NAME; $client = Zend_Gdata_ClientLogin::getHttpClient($user, $pass, $service); $spreadsheetService = new Zend_Gdata_Spreadsheets($client); $feed = $spreadsheetService->getSpreadsheetFeed(); The spreadsheet I am going to read from is a public one, so I don't really need to provide any authentication right? And what I need to provide is just the url of the spreadsheet. I tried to read the class description here but still have no idea how it can be done: http://framework.zend.com/apidoc/core/Zend_Gdata/Spreadsheets/Zend_Gdata_Spreadsheets.html

  • Exception design: Custom exceptions reading data from file?

    - by User
    I have a method that reads data from a comma separated text file and constructs a list of entity objects, let's say customers. So it reads for example, Name Age Weight Then I take these data objects and pass them to a business layer that saves them to a database. Now the data in this file might be invalid, so I'm trying to figure out the best error handling design. For example, the text file might have character data in the Age field. Now my question is, should I throw an exception such as InvalidAgeException from the method reading the file data? And suppose there is length restriction on the Name field, so if the length is greater than max characters do I throw a NameTooLongException or just an InvalidNameException, or do I just accept it and wait until the business layer gets a hold of it and throw exceptions from there? (If you can point me to a good resource that would be good too)
