• Is there an R equivalent of the pythonic "if __name__ == "__main__": main()" ?

  - by gappy

  The title says it all. The objective is to have two simple ways to source some code, say func.R, containing a function. Calling R CMD BATCH func.R initializes the function and evaluates is. Within a session, issuing source("func.R") simply initializes the function. Any idea?

• CADisplayLink stops updating when UIScrollView scrolled

  - by Tricky

  Title is quite self explanatory, but I have some animation being done in a loop triggered by CADisplayLink. However, as soon as I scroll a UIScrollView I have added to my view hierarchy, the animation stops immediately, only to return again when scrolling has completely stopped and come to a standstill.... Anyway to cancel this behaviour?

• Are methods also serialized along with the data members in .NET?

  - by Shaza

  The title is obvious, I need to know if methods are serialized along with object instances in C#, I know that they don't in Java but I'm a little new to C#. If they don't, do I have to put the original class with the byte stream(serialized object) in one package when sending it to another PC? Can the original class be like a DLL file?

• What's the easiest way to create an extensible custom container in Flex?

  - by Chris R

  I want to create an MXML container component that has some of its own chrome -- a standard query display, et al -- and that supports the addition of child components to it. Something a lot like the existing mx:Panel class, which includes a title label, but acts like a plain mx:Box with regards to adding children. What's the easiest way to do this? Edit: To be clear, I want to be able to extend the container using MXML, so the "Multiple visual children" problem is relevant.

• How does SO's form remember previous input values?

  - by user198729

  I've noticed that the Title or Body part is remembered if I come back to the Ask Question page by pressing Back button of my browser. This feature is available in all browsers I tested, but doesn't exist for the forms in my own projects. How can I approach that effect? UPDATE I still don't have any clue yet,but guess it that some kind of client cache enabled by http headers or javascript?

  - by Tommy

  I have a column that contains links. The problem is that the titles of the links are in the same column, so it looks like this: linktitle|-|linkurl I want link title and linkurl in separate columns. I've created a new column for the urls, so I'm looking for a way to extract them and update the linkurl column with them. Is there any clever way to construct a query that does this?

• scaffold does not update view

  - by doemsche

  Hi there I have a question to the following procedure: script/generate scaffold product title:string description:text db:migrate #then I generate a migration which adds a column description to the table products and migrate the db again. My question is: why is the field description not added to the project-views? Is that normal rails scaffold behaviour? I think I saw in a video tutorial that the scaffold updates as well the views, which would be very convenient. Thanks in advance for any help!

This question is not about good practices... It's about the logical value (true or false) of the question on the title.
