  • Datamapper, defining your own object methods, how?

    - by Dublinclontarf
    So lets say I have a class like below class List include DataMapper::Resource property :id, Serial property :username, String def self.my_username return self[:username] end end list=List.create(:username=>,'jim') list.my_username When I run this it tells me that the method cannot be found, and on more investigation that you can only define class methods(not object methods) and that class methods don't have access to objects data. Is there any way to have these methods included as object methods and get access to object data? I'm using Ruby 1.8.6 and the latest version of datamapper.

  • What HTTP error code should I use for unauthorised access to a protected image?

    - by Bala Clark
    I am writing a web application that has secure images uploaded by users. These images are only available to the owner when logged in. I am wondering what the best HTTP error code to throw in the case of unauthorised access? Would a 404 not found, or a 403 unauthorised be better? I am leaning towards the 403, but would it be better to hide the fact that the resource exists to unauthorised users be better?

  • What call from the Android Development Tools API should I use to poll project target loading?

    - by Ricardo Gladwell
    I'm writing my own eclipse plug-in that integrates with the Eclipse Android Development Tools (ADT). However, I'm getting a CoreException ("Project target not loaded yet.") thrown when I attempt to call IProject.build on an Android project as part of a unit test: IProject project = importProject(...); project.build(IncrementalProjectBuilder.FULL_BUILD, monitor); Should I be waiting for the project target to load before calling the above? If so, what call should I use to poll the project target loading status?

  • Did anyone give these smart pointers (auto_any, scoped_any, shared_any) a test drive?

    - by Johann Gerell
    I'm investigating smart pointers with "shared" functionality for Windows CE and Mobile, where the VS 2008 tr1 std::shared_ptr cannot be used (due to linkage to a v.9 dll not present on CE, obviously, if I understand it correctly). There's a semi-old MSDN Magazine article with sources from a Microsoftie (Eric Niebler): Achieve More Reliable Resource Management with Our Custom C++ Classes. The reasoning, design and implementation of his shared_any looks solid, but I'm wondering if anyone ever actually tested the lot on any platform (not necessarily WinCe/WM)?

  • How to modularize a JSF/Facelets/Spring application with OSGi?

    - by lexicore
    I'm working with very large JSF/Facelets applications which use Spring for DI/bean management. My applications have modular structure and I'm currently looking for approaches to standardize the modularization. My goal is to compose a web application from a number of modules (possibly depending on each other). Each module may contain the following: Classes; Static resources (images, CSS, scripts); Facelet templates; Managed beans - Spring application contexts, with request, session and application-scoped beans (alternative is JSF managed beans); Servlet API stuff - servlets, filters, listeners (this is optional). What I'd like to avoid (almost at all costs) is the need to copy or extract module resources (like Facelets templates) to the WAR or to extend the web.xml for module's servlets, filters, etc. It must be enough to add the module (JAR, bundle, artifact, ...) to the web application (WEB-INF/lib, bundles, plugins, ...) to extend the web application with this module. Currently I solve this task with a custom modularization solution which is heavily based on using classpath resources: Special resources servlet serves static resources from classpath resources (JARs). Special Facelets resource resolver allows loading Facelet templates from classpath resources. Spring loads application contexts via the pattern classpath*:com/acme/foo/module/applicationContext.xml - this loads application contexts defined in module JARs. Finally, a pair of delegating servlets and filters delegate request processing to the servlets and filters configured in Spring application contexts from modules. Last days I read a lot about OSGi and I was considering, how (and if) I could use OSGi as a standardized modularization approach. I was thinking about how individual tasks could be solved with OSGi: Static resources - OSGi bundles which want to export static resources register a ResourceLoader instances with the bundle context. A central ResourceServlet uses these resource loaders to load resources from bundles. Facelet templates - similar to above, a central ResourceResolver uses services registered by bundles. Managed beans - I have no idea how to use an expression like #{myBean.property} if myBean is defined in one of the bundles. Servlet API stuff - use something like WebExtender/Pax Web to register servlets, filters and so on. My questions are: Am I inventing a bicycle here? Are there standard solutions for that? I've found a mentioning of Spring Slices but could not find much documentation about it. Do you think OSGi is the right technology for the described task? Is my sketch of OSGI application more or less correct? How should managed beans (especially request/session scope) be handled? I'd be generally graefult for your comments.

  • Fiddler - Daily stop start

    - by weismat
    What is the best way to stop/start Fiddler as a daily task? I am usin Fiddler to monitor/logs https trafficon machine which runs fully automated and runs software which is not controlled by me, but uses https. My machine stopped yesterday because Fiddler went out of memory after running over 3 days and now I want to have a clean way to start/stop it. I guess I could just specify a process duration in the task manager, but I would prefer something cleaner, especially to avoid issues when things are started manually.

  • Recommendations for a .NET component to access an email inbox

    - by Ian Nelson
    I've been asked to write a Windows service in C# to periodically monitor an email inbox and insert the details of any messages received into a database table. My instinct is to do this via POP3 and sure enough, Googling for ".NET POP3 component" produces countless (ok, 146,000) results. Has anybody done anything similar before and can you recommend a decent component that won't break the bank (a few hundred dollars maximum)? Would there be any benefits to using IMAP rather than POP3?
