You can easily create a wiki with zena (a rails CMS): You create an empty application with zena wiki You initialize an empty database cd wiki; rake zena:init RAILS_ENV=production You set the publish, write and read groups of a node to "public" (use the wrench tool, "drive" tab) You change the anonymous user's status from "moderated" to "user" (user

What is the easiest way to deeply clone (copy) a mutable Scala object? Since you want the easiest way to deep copy a Scala object and not the fastest, you can always serialize the object, provided that it's serializable, and then deserialize it back. The following code only runs when compiled, not in REPL. def deepCopy[A](a: A)(implicit m: reflect.Manifest[A]): A = util.Marshal.load[A](util.Marshal.dump(a)) val o1 = new Something(...) // "Something" has to be serializable val o2 = deepCopy(o1) A Java-specific solution (which should work great in Scala too), is the Cloner library . It's fast,

I have a model which can be edited by a certain view; however, at the bottom of the view the user should get an option to save or discard all changes. This means that you will need to store a list of all the changes to be made to the model and then make those changes only once the 'save' button has been clicked. This sounds unnecessarily complicated and I have come up with an idea of an alternative approach which is to create a clone of the model and make changes to that in the view. Then if the user clicks 'save' delete the old model and replace it in its collection with the new one,

This question already has answers here : Implementing monads in JavaScript (3 answers) I'm trying to create a List monad in ES6 using generators. To make it work I need to create a copy of an iterator that has already consumed several states. How do I clone an iterator in ES6? function* test() { yield 1; yield 2; yield 3; } var x = test(); console.log(x.next().value); // 1 var y = clone(x); console.log(x.next().value); // 2 console.log(y.next().value); // 2 (sic) I've tried clone and cloneDeep from lodash , but they were of no use. Iterators that are returned in this way are native functions

A few days ago, I answered an interesting question on SO about HashSet<T> . A possible solution involved cloning the hashset, and in my answer I suggested to do something like this: HashSet<int> original = ... HashSet<int> clone = new HashSet<int>(original); Although this approach is quite straightforward, I suspect it's very inefficient: the constructor of the new HashSet<T> needs to separately add each item from the original hashset, and check if it isn't already present . This is clearly a waste of time: since the source collection is a ISet<T> , it is guaranteed not to contain duplicates.
