• Confusion on using django socialauth

  - by Fedor

  http://github.com/uswaretech/Django-Socialauth/tree/master/socialauth/ I'm a bit confused on how I should use this. Of course, I read the notes at the bottom but I'm a Django novice so I'll need a little hand holding. The structure of this looks like a project structure since it contains a urls.py but I'm also aware that applications can also have that. It also has a manage.py which leads me to believe it's a project ( plus the subdirectories ). So should I just be integrating portions of this into my existing project? This isn't an application, right? The README also mentions grabbing API Keys. So if I want a standard interface where you click on a google/yahoo logo and it forwards itself via Javascript to the authentication page where you login if you already aren't logged in, kicks you back to your own page, would I need API keys? Any other special tips are appreciated.

• Visual Studio 2008 freezing when editing aspx/master pages

  - by jayrdub

  Visual Studio freezes up continually when I'm editing master pages or aspx files. Here's what I've tried that have not helped: restarting VS only working with few files open at a time Disabled all addins (resharper etc.) deleted .suo and .user files changed default editor from Web Form Editor and Master Page Editor to HTML Editor installed SP1 I don't have tons of files - 3 Master pages and maybe 30 aspx files. It is a asp.net mvc project. All I have to do to get VS to freeze is type a little text or even just paste. The freezing lasts a good 5-10 seconds. My machine has 4GB of RAM and fast disks. Could it have anything to do with asp.net mvc? Would the amount and size of other projects in the solution affect the editor?

• How does jQuery stores data with .data()?

  - by TK

  I am a little confused how jQuery stores data with .data() functions. Is this something called expando? Or is this using HTML5 Web Storage although I think this is very unlikely? The documentation says: The .data() method allows us to attach data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks. As I read about expando, it seems to have a rick of memory leak. Unfortunately my skills are not enough to read and understand jQuery code itself, but I want to know how jQuery stores such data by using data(). http://api.jquery.com/data/

• Unit test with Authlogic on Rails 3

  - by Puru puru rin..

  Hello, I would like to write some unit test with a logged user using Authlogic. To start right, I used some code hosted in http://github.com/binarylogic/authlogic_example. But I get an error after rake test, because of "test_helper.rb" and the following class: class ActionController::TestCase setup :activate_authlogic end Here is my error: NameError: undefined local variable or method `activate_authlogic' for I think this Authlogic example is mapped over Rails 2; maybe it's a little bit different on Rails 3. Is there an other example where I can take example about unit test? Many thanks.

• Rough/near equivalents of Java and .NET technologies/frameworks

  - by Paul Sasik

  I work in a shop that is a mix of mostly Java and .NET technologists. When discussing new solutions and architectures we often encounter impedance in trying to compare the various technologies, frameworks, APIs etc. in use between the two camps. It seems that each camp knows little about the other and we end up comparing apples to oranges and forgetting about the bushels. While researching the topic I found this: Java -- .Net rough equivalents It's a nice list but it's not quite exhaustive and is missing the key .NET 3.0 technologies and a few other tidbits. To complete that list: what are the near/rough equivalents (or a combination of technologies) in Java to the following in .NET? WCF WPF Silverlight WF Generics Lambda expressions Linq (not Linq-to-SQL) ...have i missed anything else? Note that I omitted technologies that are already covered in the linked article. I would also like to hear feedback on whether the linked article is accurate. Thanks. (Will CW if requested.)

• JD Edwards... call C#?

  - by rbobby

  Hey all, I know very little about JD Edwards. I have a client asking how to call an API we supply (as COM, C#, REST) from JD Edwards. I'm not getting much in terms of high quality answers from their tech guy... so I thought I'd ask here. Can JD Edwards call C#? Can JD Edwards call Java? Can JD Edwards call a Unix scipt? Can anyone point me towards anything useful in terms of developer/customization documentation? Thanks!

• Localizing concatenated or dynamic strings

  - by SooDesuNe

  I'm familiar with using NSLocalizedString() to localize strings, but the problem I have today requires a little more finesse. My situation is like this: NSString *userName; //the users name, entered by the user. Does not need localized NSString *favoriteFood; //the users favorite food, also entered by user, and not needing localized NSString *summary = [NSString stringWithFormat:@"%@'s favorite food is %@", userName, favoriteFood]; This works fine for english, but not every language uses the same word ordering as English, for example, a word-by-word translation of the same sentance from Japanese into English would read: UserName's favorite food pizza is Not to mention that 's is doesn't make a possessive in every language. What techniques are available for localizing this type of concatenated sentence?

• mvvm-light: Should we merge Cleanup methods in locator?

  - by mark smith

  Hi there, when creating a new ViewModel within the locator class using the snippet it creates a Cleanup Method but there is already one available from the Main so hence an error.... Should we merge them all?? Or should we be renaming the method to Cleanup[Name of viewmodel] for example. I am a little confused here Another question i would like to ask is regards to the naming conventions. I tried to follow the naming convention used with "MAIN"... hence i have CreateLogin, ClearLogin, Login (non static property for binding) etc etc.. Would it not be better to use CreateLoginViewModel, ClearLoginViewModel etc?? Just curious Thanks

• Using OpenGL drawing operations in an object-oriented setting?

  - by Lion Kabob

  I've been plowing through basic shaders and whatnot for an application I'm writing, and I've been having trouble figuring out a high-level organization for the drawing calls. I'm thinking of having a singleton class which implements a number of basic drawing operations, taking data from "user" classes and passing that to the appropriate opengl calls. I'm wondering how people do this when writing their own applications, as the internet is chock full of basic "Your first shader" tutorials, but very little on suggested organization of drawing code. My particular environment is targeted at iPad/OpenGL ES 2.0, but I think the question stands for most environments.

• My HttpHandler doesn't want to create directory on a network

  - by Daok

  I use this simple line of code inside my HttpHandler: Directory.CreateDirectory(@"\\srv-001\dev\folderToCreate\"); I receive an UnauthoridezAccessException telling me that the access to the path is denied. From here, I create a little Dos application in C# doing the same thing and I was able to create the folder. So, I thought that it might be that IIS is running on a different user than myself. I went to IIS and changed the Application pool to a Custom user, myself. But, unfortunately, I got the same exception. I have try to create a Share folder on my computer and I can create directory. Also, when debugging I can see that System.Threading.Thread.CurrentPrincipal.Identity have its AuthenticationType to "", IsAuthenticated to false and name to "". So, with all those tests I can conclude that the HttpHandler that receive the file cannot create a directory because of some security access. How can I grand access to my HttpHandler to be able to create a directory (and files) to a network folder?

• How To Test if Type is Primitive

  - by DaveDev

  Hi Guys I have a block of code that serializes a type into a Html tag. Type t = typeof(T); // I pass <T> in as a paramter, where myObj is of type T tagBuilder.Attributes.Add("class", t.Name); foreach (PropertyInfo prop in t.GetProperties()) { object propValue = prop.GetValue(myObj, null); string stringValue = propValue != null ? propValue.ToString() : String.Empty; tagBuilder.Attributes.Add(prop.Name, stringValue); } This works great, except I want it to only do this for primitive types, like string, int, double, bool etc. I want it to ignore everything else. Can anyone suggest how I do this? Or do I need to specify the types I want to allow somewhere and switch on the property's type to see if it's allowed? That's a little messy, so it'd be nice if I there was a tidier way.

• parsing expression trees with booleans

Any help would be great. Thanks.

• How to pre-process CSV data for FasterCSV?

  - by Katherine Chalmers

  We're having a significant number of problems creating a bulk upload function for our little app. We're using the FasterCSV gem to upload data to a MySQL database but he Faster CSV is so twitchy and precise in its requirements that it constantly breaks with malformed CSV errors and time out errors. The csv files are generally created by users' pasting text from their web sites or from Microsoft Word docs so it is not reasonable to expect that there will never be odd characters like smart quotes or accents in the data. Also users aren't going to be readily able to identify whether their data is perfect enough for FasterCSV or not. We need to find a way to fix it for them automatically. Is there a good way or a reliable tool for pre-processing CSV data to fix any nits in the data before having the FasterCSV gem process it?

• EE Major : Should I learn Ruby on Rails or Haskell?

  - by Vivek

  Hi,I've just completed my freshman year in college and am majoring in EE (with a lot of interest in CS as well) . I know some Python,C/C++ and Java and also a little bit of Actionscript . I am planning to learn either Haskell or Ruby on Rails. Haskell because it is a functional programming language, and I've been really impressed by this paradigm and Ruby on Rails , as I don't know any 'web' programming language and have heard that you can develop apps in RoR very easily and quickly . Which one should I learn ? and please suggest some links / books for starting off .

• .NET - downloading multiple pages from a website with a single DNS query

  - by lampak

  I'm using HttpRequest to download several pages from a website (in a loop). Simplifying it looks like this: HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create( "http://sub.domain.com/something/" + someString ); HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); //do something I'm not quite sure actually but every request seems to resolve the address again (I don't know how to test if I'm right). I would like to boost it a little and resolve the address once and then reuse it for all requests. I can't work out how to force HttpRequest into using it, though. I have tried using Dns.GetHostAddresses, converting the result to a string and passing it as the address to HttpWebRequest.Create. Unfortunately, server returns error 404 then. I managed to google that's probably because the "Host" header of the http query doesn't match what the server expects. Is there a simple way to solve this?

• WCF Web Service chnage wsdl name and targetNamespace

  - by Graham

  All, I'm a little new to WCF over IIS but have done some ASMX web services before. My WCF service is up and running but the helper page generated by the web service for me has the default names, i.e. the page that says: You have created a service. To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax: svcutil.exe http://localhost:53456/ServicesHost.svc?wsdl In a standard ASMX site I would use method/class attributes to give the web service a name and a namespace. When I click on the link the WSDL has: <wsdl:definitions name="SearchServices" targetNamespace="http://tempuri.org/" i.e. not the WCF Service Contract Name and Namespace from my Interface. I assume the MEX is using some kind of default settings but I'd like to change them to be the correct names. How can I do this?

• Common MVC 2 Pitfalls

  - by mcass20

  I surprised this hasn't been asked before...or maybe I just don't see it. Anyway, I'm finally straying from the comfort of ASP.NET Web Forms and exploring the world of MVC2. I've done the nerdinner walk-through and it was fairly straightforward. Now I am getting a little more adventurous and building an MVC2 app on my own and would like to know if there are some common pitfalls that others can attest to. Please consider my background as an ASP.NET Web Forms developer. Thanks!

• In python: how to apply itertools.product to elements of a list of lists

  - by Guilherme Rocha

  I have a list of arrays and I would like to get the cartesian product of the elements in the arrays. I will use an example to make this more concrete... itertools.product seems to do the trick but I am stuck in a little detail. arrays = [(-1,+1), (-2,+2), (-3,+3)]; If I do cp = list(itertools.product(arrays)); I get cp = cp0 = [((-1, 1),), ((-2, 2),), ((-3, 3),)] But what I want to get is cp1 = [(-1,-2,-3), (-1,-2,+3), (-1,+2,-3), (-1,+2,+3), ..., (+1,+2,-3), (+1,+2,+3)]. I have tried a few different things: cp = list(itertools.product(itertools.islice(arrays, len(arrays)))); cp = list(itertools.product(iter(arrays, len(arrays)))); They all gave me cp0 instead of cp1. Any ideas? Thanks in advance.

• Scaled live iPhone Camera view in center, "CGAffineTransformTranslate" not working

  - by Gavin

  Hi, I have a little problem which I could not solve. I really hope someone can help me with that. I wanted to resize the live camera view and place it in the center, using the following code below: picker.cameraViewTransform = CGAffineTransformScale(picker.cameraViewTransform, 0.5, 0.56206); picker.cameraViewTransform = CGAffineTransformTranslate(picker.cameraViewTransform, 80, 120); But all I got was a scaled 1/2 sized view on the top left of the screen. It seems as though "CGAffineTransformTranslate" does nothing at all. The translation didn't work even when I used: picker.cameraViewTransform = CGAffineTransformMake(1, 0, 0, 1, 80, 120); The translation portion seems to have no effect on the live camera view. Hope someone can enlighten me. Thanks.

• SubSonic IQueryable To String Array

  - by Daniel Draper

  Hey All, I have decided to use SubSonic (v3.0) for the first time and thoroughly enjoy it so far however I seem to have stumbled and I am hoping there is a nice neat solution. I have a users, roles and joining table. SubSonic (ActiveRecord) generated an entity User for my users table. A property of User is UserRoles and is of the type IQueryable this is my joining table. I want to convert the IQueryable column name RoleName to a string array. I have only just started playing with Linq as well and know of ToArray() but seem to be missing something or this isn't the function I want. I could iterate over each item in the UserRoles property but seems a little excessive. I appreciate your help! Cheers.

• HTML: upload-form in an other form

  - by chris

  hi! I have a little problem with an upload-form within an other form (call it data-form). I know it is not possible to put a form into an other. So I would need to put it after my data-form. But I need the upload-form controls in the middle of my data-form because of optical and structural reasons. The file-upload should also perform other actions and not the same than the data-form. So any idea how can I make the upload-form after my data-form but visible in it or any other ideas to handle this? I am using javascirpt and php also. thanks and best wishes for 2011! br,chris
