UIViewController default's behavior without XIB and without overriding loadView - documentation?
See the documentation for the loadView method: If the view controller has an associated nib file, this method loads the view from the nib file. A view controller has an associated nib file if the nibName property returns a non-nil value, which occurs if the view controller was instantiated from a storyboard, if you explicitly assigned it a nib file using the initWithNibName:bundle: method, or if iOS finds a nib file in the app bundle with a name based on the view controller’s class name. If the view controller does not have an associated nib file, this method creates a plain UIView object instead.

Overriding bootstrap wizard default behavior
Right after instantiate the wizard, you can use jQuery's off() function to remove the handler, then use the on() function to add your own: var selector = 'li.already-visited a.wizard-nav-link'; (".wizard-steps").off('click', selector).on("click", selector, function(event) { //your own handler here });

iOS - UIViewController - Runtime error when overriding a getter in UIViewController subclass chain
First of all, if you call self.someClass in your getter you end up in a loop as self.someClass it's actually calling that same method. This is probably the reason of your crash. Secondly, every UIViewController instance always has a view (the scene you're talking about?) associated with it, hence all the -viewDidLoad, -viewWillAppear, etc. methods. Lastly, it's very bad to have a 'common view controller' to handle stuff. You may want to use the delegation pattern or the singleton pattern instead.

Haddock: Documentation for instance functions with quirks replaced by default class documentation
You can't. What you can do is document your instance. -- | You can have a brief description here instance (Monad m) => MonadState s (ChronoT s e m) where … This will make the description show up to the side of the instances box generated. This should preferably be brief but it does let you do things such as point the user to documentation of the functions implementing the fields if you really need to, like the commenter on the question suggests. Personally, I think that it doesn't make much sense to document each field like this: what the fields are meant to do should be clear from documentation of the class definition and the comment on the instance.

The cabal-config.in file is a template that is used for initialising cabal-dev/cabal.config when creating a new sandbox. If you want to enable documentation for an already existing cabal-dev sandbox, just edit cabal-dev/cabal.config.

Default CSS overriding media query
I thought media queries were to overrule generic class rules, Rules inside a MQ are rules like any other one in terms of priority of their selector, except they will only apply depending on the conditions of the at-media. (...) I also realize that the rule for non-media-queried container h1 is declared AFTER the media query rule. You found the correct reason: both rules have exactly the same priority (specificity) as they have the exact same selector. If a property is part of both rules (and the declaration is valid and both of them or none of them has !important modifier), then the value of the last declaration written will apply. That's the reason you'll always find MQ written at the end (except rules applying to IE8- via conditional classes, no possible overlap between MQ

Why does the default constructor always appear in javadoc documentation, even though it is not present in the code?
According to http://docs.oracle.com/javase/tutorial/java/javaOO/constructors.html: The compiler automatically provides a no-argument, default constructor for any class without constructors That means, that the default constructor will be added implicitly in a compile time. At the time, when it gets for javadoc, it is already added. This is specified here http://www.oracle.com/technetwork/java/javase/documentation/index-137868.html#defaultconstructors: Section 8.8.7 of the Java Language Specification, Second Edition describes a default constructor: If a class contains no constructor declarations, then a default constructor that takes no parameters is automatically provided. It invokes the superclass constructor with no arguments. The constructor has the same access as its class. The Jav

Java: Switch default overriding try-catch
Your sAction variable is always a String, since Scanner.nextLine() returns String. Therefore, your default statement is triggered, and it's reasonable to assume the InputMismatchException catch will never execute. See also the other Scanner "next" methods if you'd like to fine-tune your input acceptance. Example: while (true) { // your infinite loop - better use a while-do instead of a do-while here String sAction = input.nextLine(); // we assign sAction iteratively until user "quits" // No try-catch: ArrayIndexOutOfBoundsException is unchecked and you shouldn't catch it. // If it bugs, fix the code. // No InputMismatchException either, as you don't need it if you use nextLine // your switch same as before }

Overriding Go's default HTTP Sever redirect behaviour
I'd like to disable this behaviour and handle all paths myself. I'm a Go newbie, and it seems as if I could create my own Server instance and override the Handler attribute, but I'm not sure how to? Instead of registering handlers with the http.DefaultServeMux through the http.Handle or http.HandleFunc methods just call: http.ListenAndServe(":8080", MyHandler) where MyHandler is an instance of a type that implements the http.Handler interface. http.ListenAndServe in turn is just a short-hand method that does the following: func ListenAndServe(addr string, handler http.Handler) error { server := &http.Server{Addr: addr, Handler: handler} return server.ListenAndServe() } so you could do that directly instead as well. Inside your handler you can then parse/route

Vim: what's the default backspace behavior?
Generally it does not matter that it is called "Delete" on Mac keyboards. Technically Apple gets away with this by calling that key "Backward Delete". And what we traditionally think of as a delete key, Apple calls "Forward Delete". To get "Forward Delete" behavior you must press fn + delete. Now, back to the real issue, vim... the default setting for backspace in OS X is this (/usr/share/vim/vimrc): set backspace=2 " more powerful backspacing Your custom vimrc should override this if you want the behavior you discussed in your question. There are two other factors that may lead to strange behavior with respect to backspace in vim. Terminal software can be configured to send either Delete or Backspace when you press this key. (This option is usually called something like "send ^

What's the c++'s default assign operation behavior?
Default assign (and copy) behaviour does not memcpy the whole class, which would break things. Each member is copied using their copy constructor or assignment operator (depending on operation). This is applied recursively for members and their members. When a basic data type is reached, it simply performs a straight copy of data, similar to memcpy. So an array of basic data types may be copied similar to memcpy, but the whole class is not. If you add std::string to your class its = operator would be called, alongside copy of array. If you used array of std::string, each string in your array will have their operator called. They won't memcpy.

How to allow loadView to be sent to my NSViewController?
loadView is typically not called if you are using a nib (since view is already set). But the real question is why you're trying to fight the view loading process this way. If awakeFromNib is being called multiple times, that suggests you have multiple instances of this class. Each will get a call to awakeFromNib (that is expected behavior). If this is surprising, you should dig into why you have multiple instances. But you shouldn't try to subvert the view-loading mechanism like this.

Why self.view.tag in loadview is different with others
The loadView method is not usually implemented. The system calls it in order to create your view hierarchy. At the time it's called, your views will not exist. Why are you implementing loadView? You probably should not be. To quote the docs: If you use Interface Builder to create your views and initialize the view controller, you must not override this method. What code are you putting in your loadView method?

Should I call dismissViewController on the modal UIViewController or the UIViewController that presented it?
Why and How Let's say, view controller A has presented B, and B has presented C in turn. When you call dismissViewControllerAnimated:completion:, iOS checks to see if the view controller you're calling it on has a child in its presentedViewController property. If it does, then it dismisses that controller. So if I call it on B in our example, it dismisses C, but if I call it on A, it dismisses B (which takes away C with it). If I call it on C, then it has no child. So then iOS checks the presentingViewController property. If that is set, it asks it to dismiss its controller. So if I call it on C, iOS sends the request back to B, which dismisses C. So calling the method on either B or C will get rid of C, while calling it on A gets rid of B and C. Best Practice Call it on B, on the t

Javascript event handler to execute after default behavior
You could perform the default action yourself, then do what you want, and then prevent the default action from running. <form target="_blank" action="submit.php" onsubmit="this.submit(); doThisAfterSubmit(form); return false;"> <input type="submit" /> </form> Note: Calling this.submit() in "onsubmit" will not cause an infinite loop as you might think. jsfiddle demo EDIT: My original jsfiddle was only displaying text after the form submit. I tried it again, but changed it to remove the form like you want. That caused the form to no longer submit, even though this.submit() was called first. In that case, you can use setTimeout() to delay the removal of the form until the original thread is finished executing, like this: function doThisAfterSubmit(form) {

SynchronizationContext default behavior in TAP (Task Async Pattern)
First off, the article you referenced is talking about BackgroundWorker and not async. BackgroundWorker still works the same way in .NET 4.5, and still has the limitation around nested calls. For a description of how async works with SynchronizationContext, you can look at the end of that article or read my intro on async. In short, when an await is encountered, by default it will capture the current SynchronizationContext (or if it's null, the current TaskScheduler), and use that to schedule the continuation.

Create UIView on previous UIViewController from another UIViewController
That code crashes because it's trying to read the vc from a nibNamed:nil. Even if you got that working, it wouldn't work. The code isn't changing the VideoPlayerVC that pushed the current vc, it's just allocating a new one (trying to) and changing a view on that new one, which gets released right after that method finishes. The way to see the presenting view controller in a navigation container is to access self.navigationController.viewControllers. NSArray *vcs = self.navigationController.viewControllers; VideoPlayerViewController *previousVC = vcs[MAX(0, vc.count-2)]; [previousVC setMovieCompare ...]; Reaching down the navigation array may not be the best thing, especially of other view controllers can present the current vc.
