  • rails declarative authorization, permit all actions for controller?

    - by SooDesuNe
    using the delcarative_authorization gem for rails, is there a shortcut to allow a role access to all controller actions? privileges do # default privilege hierarchies to facilitate RESTful Rails apps privilege :manage, :includes => [:create, :read, :update, :delete] end isn't sufficient, because I have more controlling methods than just CRUD in my controllers. Something like: role :foo do has_permission_on :bar, :to =>[:all] end would be perfect, but I'm not finding it in the docs.

    In Android, if I want to do some background work, what is the difference between Creating a Service to do the work, and having the Activity start the Service VS.

  • Is SPLFileObject atomic?

    - by Jakub Lédl
    I'm wondering whether methods of PHPs SPLFileObject are atomic (e.g. thread-safe) or not? If they aren't, I'll implement my own class, which will use flock(), but is this enough? Is the flock function really thread-safe? What if the collision occurs after I fopen() the file, but before I flock() it?

  • Are you human? (or How to prevent spam)

    - by pek
    What mechanisms do you know that prevent your site from being abused by anonymous spammers. For example, let's say that I have a site where people can vote something. But I don't want someone to spam something all the way to the top. So I found (a) creating an account and only allowed to vote once and (b) CAPTCHA to decrease spam. What other methods do you know and how good do they work?

  • is Checkland's approach still relevant today?

    - by WeNeedAnswers
    I remember back in the mid 90's that I came across a systems methodology called Checkland's Approach or sometimes called SSM (Soft Systems Methodology). With the advent of Agile and Extreme Programming, not to mention some of the harder methodologies and methods out there related to Object technologies. Is the use of such a methodology still relevant in today's world?

  • Method Vs Property

    - by obsoleteattribute
    Hi, I'm a newbie to .NET. I have a class called Project, a project can have multiple forecasts.Now If I want to check if the projects has any forecasts or not should I use a readonly boolean property called HasForecast() or should I use a method named HasForecast() which basically returns a boolean value.From framework design guidelines I came to know that methods should be used when the operation is complex,since here I'm retrieving the value of forecasts from DB should I consider method, or since it is a logical data member should I use a property.If I use a property can I call a method in DBLayer from its getter.Please explain Regards, Ravi

  • Block users using auto-clickers

    - by James Simpson
    I'm having some problems with users cheating my online game by using macros to automatically click certain spots on the screen in a certain order to automate various tasks without having to actually be playing the game. Are there any methods that can be used to block this kind of activity without having to plaster CAPTCHAs all over the site and ruin the experience for the honest users?

  • Why won't anyone accept public fields in C#?

    - by Dmitri Nesteruk
    Seems like every C# static analyzer wants to complain when it sees a public field. But why? Surely there are cases where a public (or internal) field is enough, and there is no point in having a property with its get_ and set_ methods? What if I know for sure that I won't be redefining the field or adding to it (side effects are bad, right?) - shouldn't a simple field suffice?

  • Built-in precedence in Expression Trees?

    - by jdk
    I'm unable to find the .NET FCL built-in concept of precedence to leverage while constructing Expression Trees. Ref System.Linq.Expressions Namespace. Is this something that must be handled manually in code, or is it somehow implicit and I'm not recognizing it? Maybe through helper methods or classes? I want to apply it to math operations to ensure 3 + 5 * 10 results in 53 instead of 80.

  • How can I merge properties of two JavaScript objects dynamically?

    - by JC Grubbs
    I need to be able to merge two (very simple) JavaScript objects at runtime. For example I'd like to: var obj1 = { food: 'pizza', car: 'ford' } var obj2 = { animal: 'dog' } obj1.merge(obj2); //obj1 now has three properties: food, car, and animal Does anyone have a script for this or know of a built in way to do this? I do not need recursion, and I do not need to merge functions, just methods on flat objects.

  • Updating protected using update_all

    - by Jack
    Since you cannot use the normal 'update' and 'update_attribute' methods from ActiveRecord to update a protected attribute, is the following the best way to update an attribute for a single user? User.update_all("admin = true","id = 1") I'm guessing this doesn't lie in the 'best practice' category, so I'm just curious if there is a more appropriate way.

  • Calling method after view has loaded

    - by iamdadude
    My iPhone app allows for users to type in their usernames and passwords so that they can login. When they login once, their usernames and passwords are saved so that users don't have to type it in again. My problem is, when the app starts again, it immediately starts logging them in, leaving the interface completely black. How would I go about calling my login method AFTER all the UI methods are loaded?

  • How would I go about prevent DLL injection.

    - by wowus
    So the other day, I saw this: http://www.edgeofnowhere.cc/viewtopic.php?p=2483118 and it goes over three different methods of DLL injection. How would I prevent these from the process? Or at a bare minimum, how do I prevent the first one? I was thinking maybe a Ring 0 driver might be the only way to stop all three, but I'd like to see what the community thinks.

  • Basic Java Multi-Threading Question

    - by Veered
    When an object is instantiated in Java, is it bound to the thread that instantiated in? Because when I anonymously implement an interface in one thread, and pass it to another thread to be run, all of its methods are run in the original thread. If they are bound to their creation thread, is there anyway to create an object that will run in whatever thread calls it?
