  • Rails OpenID Authentication Plugin No Longer Installs Rake Tasks?

    - by Rich Apodaca
    I'm following the Railscasts tutorial on using OpenID with AuthLogic. This command: $ script/plugin install git://github.com/rails/open_id_authentication.git installs the plugin, but I don't see any OpenID Rake tasks (rake -T). In particular, I can no longer run the task: $ rake open_id_authentication:db:create With previous applications, the Rake tasks were installed without a problem, so what's changed with the plugin? Which version of the plugin do I need to get the behavior I'm looking for? Using Rails 2.3.5.

  • F# for C#/Haskell programmer

    - by Maciej Piechotka
    What is recommended tutorial of F# for Haskell programmer? F# seems to borrow a lot from Haskell but there are little traps which makes hard to write. Generally I need walkthrough the F# which would not explain what is the difference between mutable data and immutable (Haskell is much more strict in this area) etc. I know C# a little so I know more or less what .Net is about as well.

  • AD - DirectoryServices: VBNET2.0 - Speaking architecture...

    - by Will Marcouiller
    I've been mandated to write an application to migrate the Active Directory access models to another environment. Here's the context: I'm stuck with VB.NET 2005 and .NET Framework 2.0; The application must use the Windows authenticated user to manage AD; The objects I have to handle are Groups, Users and OrganizationalUnits; I intend to use the Façade design pattern to provider ease of use and a fully reusable code; I plan to write a factory for each of the objects managed (group, ou, user); The use of Attributes should be useful here, I guess; As everything is about the DirectoryEntry class when accessing the AD, it seems a good candidate for generic types. Obligatory features: User creates new OUs manually; User creates new group manually; User creates new user (these users are services accounts) manually; Application reads an XML file which contains the OUs, groups and users to create; Application informs the user about the OUs, groups and users that shall be created; User specifies the domain environment where to migrate the XML input file designated objects; User makes changes if needed, and launches the task operations; Application performs required by the XML input file operations against the underlying AD as specified by the user; Application informs the user upon completion. Linear features: User fetches OUs, groups, users; User changes OUs, groups, users; User deletes OUs, groups, users; The application logs AD entries and operations performed, plus errors and exceptions; Nice-to-have features: Application rollbacks operations on error or exception. I've been working for weeks now to get acquainted with the AD and the System.DirectoryServices assembly. But I don't seem to find a way to be fully satisfied with what I'm doing and always looking for better. I have studied Bret de Smet's Linq to AD on CodePlex, but then again, I can't use it as I'm stuck with .NET 2.0, so no Linq! But I've learned about Attributes, and seen that he's working with generic types as he codes a DirectorySource class to perform the operations for OUs, groups and users. Any suggestions? Thanks for any help, code sample, ideas, architural solution, everything!

  • Create your own HTML Textfield with Javascript

    - by teehoo
    I came across the following http://ckeditor.com/demo , and was wondering if anyone had a basic tutorial how to implement this (or perhaps what key search terms I should use)? Is this just a heavily modified TextField, or have they somehow managed to create a completely new TextField from scratch? I tried googling this many times, and I always get pages relating to customizing the built-in TextField with CSS etc.

  • Any good source of explanatory documentation on ColorMatrix?

    - by mackenir
    I'd like to try using ColorMatrix, but am only able to find examples that convert an image to grayscale. And even then, they tend to be presented as a chunk of 'magic numbers' code with no explanation. Does anyone know of a 'tutorial' on how to use ColorMatrix? For example I'd be interested in converting a grayscale image to a color image, where white == transparent, and black = a solid color, with gray pixels somewhere in between. Could ColorMatrix do that?

  • Equivalent of http://www.cplusplus.com/ for C# .net

    - by David Relihan
    Hi Folks I've read through a lot of the "Learn C# .Net" questions just to see if this question was answered already (directly or indirectly). I program mostly in C++ so I find the website http://www.cplusplus.com/ invaluable and there's rarely a day when it is not open in my browser! However, I'm just wondering is there an C# .Net equivalent that people find themselves constantly referencing? The best I'm aware of is: http://stackoverflow.com http://msdn.microsoft.com/en-us/vcsharp/aa336809.aspx http://www.java2s.com/Tutorial/CSharp/CatalogCSharp.htm Thanks,

  • Advantage of creating a generic repository vs. specific repository for each object?

    - by LuckyLindy
    We are developing an ASP.NET MVC application, and are now building the repository/service classes. I'm wondering if there are any major advantages to creating a generic IRepository interface that all repositories implement, vs. each Repository having its own unique interface and set of methods. For example: a generic IRepository interface might look like (taken from this answer): public interface IRepository : IDisposable { T[] GetAll<T>(); T[] GetAll<T>(Expression<Func<T, bool>> filter); T GetSingle<T>(Expression<Func<T, bool>> filter); T GetSingle<T>(Expression<Func<T, bool>> filter, List<Expression<Func<T, object>>> subSelectors); void Delete<T>(T entity); void Add<T>(T entity); int SaveChanges(); DbTransaction BeginTransaction(); } Each Repository would implement this interface (e.g. CustomerRepository:IRepository, ProductRepository:IRepository, etc). The alternate that we've followed in prior projects would be: public interface IInvoiceRepository : IDisposable { EntityCollection<InvoiceEntity> GetAllInvoices(int accountId); EntityCollection<InvoiceEntity> GetAllInvoices(DateTime theDate); InvoiceEntity GetSingleInvoice(int id, bool doFetchRelated); InvoiceEntity GetSingleInvoice(DateTime invoiceDate, int accountId); //unique InvoiceEntity CreateInvoice(); InvoiceLineEntity CreateInvoiceLine(); void SaveChanges(InvoiceEntity); //handles inserts or updates void DeleteInvoice(InvoiceEntity); void DeleteInvoiceLine(InvoiceLineEntity); } In the second case, the expressions (LINQ or otherwise) would be entirely contained in the Repository implementation, whoever is implementing the service just needs to know which repository function to call. I guess I don't see the advantage of writing all the expression syntax in the service class and passing to the repository. Wouldn't this mean easy-to-messup LINQ code is being duplicated in many cases? For example, in our old invoicing system, we call InvoiceRepository.GetSingleInvoice(DateTime invoiceDate, int accountId) from a few different services (Customer, Invoice, Account, etc). That seems much cleaner than writing the following in multiple places: rep.GetSingle(x => x.AccountId = someId && x.InvoiceDate = someDate.Date); The only disadvantage I see to using the specific approach is that we could end up with many permutations of Get* functions, but this still seems preferable to pushing the expression logic up into the Service classes. What am I missing?

  • MapKit Annotations and User location

    Hi all, I followed this tutorial to make my first app: http://icodeblog.com/2009/12/21/introduction-to-mapkit-in-iphone-os-3-0/ I would really like to know how to sort the annotations in the Table in order of distance to the user (the nearest annotation is the first one on the table) How is it possible to do that? I understand that I must use the CLLocation to find the user's location but then I have no idea. Could any one help me? Cheers, Thank you in advance for your much appreciated help, teddafan

  • Any good tutorials on using OAuth with Piston?

    - by Hank Gay
    I've looked at the relevant section of the Piston documentation, but it only seems to focus on how to turn it on, not what it would look like for clients or how to test it to verify it's working. The example only seems to use HTTP Basic and curl. Finally, Ned Batchelder's question makes it look like a tutorial is in order. Thanks.
