• iOS: how to understand the role of rootviewcontroller and its relationship with other objects

  - by Anthony Kong

  I have created a UISplitViewController based iOS app in XCode 3.2.5 Below is a screen shot of Interface builder showing the rootviewcontroller and how it is linked to other objects. Being a beginner myself, I do not understand: 1) What is the role of the rootviewcontroller? Searched the documentation but what I found did not answer this question. 2) I thought a IBOutlet should only link to one corresponding object. Why in this case the rootviewcontroller is linked to two?

• Shared Hudson installation - how to enable access to git over ssh?

  - by tputkonen

  We are trying to set up a Hudson server and share it between different projects. Hudson authenticates users against our Windows domain AD, and the project based security matrix makes it easy to manage who can access which projects. Remaining issue is, that most of the projects use git over ssh. Is there a way to make shared Hudson access git so that each project could create their and manage their own jobs without compromising security?

• Recipes/tutorials/libraries for GUI-like terminal navigation (vim/lynx-style)?

  - by qgi

  Several console based applications like vim or lynx offer a rich user interface which enables the user to navigate freely around the console, manipulate data directly on screen, access menus and much more, similar to "modern" gui applications. How is that being achieved in principal on Unix/Linux with C++? Do you directly manipulate some kind of character buffer or is the screen constantly cleared and reprinted to stdout? Is there a set of libraries to implement such behavior or even some kind of a "modern" event-driven GUI toolkit for the console?

• What's the best way to generate an API reference document using a Rails routes.rb file?

  - by RNHurt

  I am trying to document the API for my Rails application and I can't help but wonder if there is a better way to generate an XML file based on my routes.rb file. I'm envisioning something similar to the output of rake routes but in a more friendly, XML type format. Corey has some interesting ideas about using reflection/introspection on the routes file here but it's not quite what I need. Please tell me this is a solved problem and I'm not the first one to think of this. :)

• Fluid width Son of Suckerfish dropdown menus

  - by derekerdmann

  For CSS dropdown menus, I usually stick with the Son of Suckerfish dropdowns. The technique works extremely well, but there's one small thing that's always bothered me: the width of the dropdown links is always fixed. Are there any ways to automatically resize the width of the items in a Suckerfish dropdown menu? If not, are there any other CSS-based dropdown menu strategies that can accomplish this?

• Can I write a module/filter that gets fired before the web app get's run in Tomcat?

  - by Blankman

  Can I write a module/filter that gets put into the processing pipleline in Tomcat BEFORE the web application even gets run? Something that I could turn on/off for each web application that tomcat is handling. is this possible? So basically it would be a re-usable filter that hooks into the web pipeline that could alter the requests behavior or perform/modify the requests. One example would be to log all ip's, or redirect based on the url, block the request, etc.

• What is the easiest way to generate a Valid x:Name?

  - by just in case

  I am generating some Xaml based on some other source of input. In some cases I am generating x:Name values but they have invalid characters. I found this article on MSDN: XamlName Grammar Which describes the grammar of a x:Name tag but doesn't tell me how to actually apply this. Clearly there is some code to validate this name at runtime but what is the easiest way to actually fix up a string with invalid characters?

• jQuery Prototype conflict, alternative solutions

  - by lbolognini

  I have a problem as I'm conditionally including the Prototype-based Lightbox script for IE6 as it works better than the jQuery plugin. Of course the two libraries conflict but the official solution is not really feasible for me as i would have to replace tons of $ with the alternative no-conflict syntax. Is there any other solution for me, keeping in mind that in my case it would be easier to have Prototype work nicely with jQuery than the other way around?
