How to populate a Scala List with sample data (examples)

As a quick note, I was just reminded that you can populate a Scala List using a Range, like this:

scala> (1 to 5).toList
res0: List[Int] = List(1, 2, 3, 4, 5)

scala> (1 to 10 by 2).toList
res1: List[Int] = List(1, 3, 5, 7, 9)

scala> (5 to 11).toList
res2: List[Int] = List(5, 6, 7, 8, 9, 10, 11)

scala> ('d' to 'h').toList
res3: List[Char] = List(d, e, f, g, h)

Those are just a few examples. For many more ways to populate Scala lists with sample data, see How to populate Scala collections with a Range, How to generate random numbers, characters, and sequences in Scala, and Different ways to create and populate Lists in Scala.

fMRI software bugs upend years of research

I’ve seen several articles about major software bugs (and a lack of testing) recently, and one of them is related to MRI/fMRI image processing. From this article at

When you see a claim that “scientists know when you're about to move an arm: these images prove it”, they're interpreting what they're told by the statistical software.

A whole pile of “this is how your brain looks like” fMRI-based science has been potentially invalidated because someone finally got around to checking the data.
