Is there something that makes it so that only "is" should be available or has "isnt" just been forgotten about?

• Can any framework project use Struts-taglib

  - by ChronoXIII

  I have read here that one disadvantage that some may find with using Spring MVC over Struts is that Struts has tags that output HTML code, while Spring has tags that don't generate HTML. My question is can't you just use the Struts tag-lib in a Spring MVC project (or any other kind of framework project), by dropping the right jar into the WEB-INF/lib folder? Any clarification is appreciated, thanks.

• Should BASIC continue to be recommended for non-programmers and beginners?

  - by Casey

  I just came across a new BASIC implementation for Google Android application called Simple. You can read about it here: http://google-opensource.blogspot.com/2009/07/programming-made-simple.html Clearly, a lot of time and effort has been recently put into enabling this functionality for Android. Should the software industry continue to encourage non-programmers into learning BASIC, or are modern languages like C#, Python, Ruby more appropriate at this time?

• scala for yield setting a value

  - by coubeatczech

  Hi, I want to create a list of GridBagPanel.Constraints. I read it in the scala programming book, that there is a cool for-yield construction, but I probably haven't understood the way it works correctly, because my code doesn't compile. Here it is: val d = for { i <- 0 until 4 j <- 0 until 4 } yield { c = new Constraints c.gridx = j c.gridy = i } I want to generate a List[Constraints] and for every constraint set different x,y values so later, when I later add the components, they're going to be in a grid.
