folder

If you ever need to generate a list of subdirectories in a directory in Scala, here's one way to do it:

def getListOfSubDirectories(directoryName: String): Array[String] = {
  return (new File(directoryName)).listFiles.filter(_.isDirectory).map(_.getName)
}

I intentionally wrote that function in a short, "Scala like" style, but you can expand it to multiple lines, if you prefer.

To demonstrate the use of this directory-listing function, you can print all your subdirectories like this:

Mac Desktop font size FAQ: How do I adjust the Mac Desktop font size? (Related: How do I adjust the Mac Desktop icon size?)

You can adjust the Mac Desktop font size (and Mac Desktop icon size) by right-clicking on an open area of your Mac Desktop, then selecting Show View Options.

Mac Dock FAQ: How do I move a commonly used Mac folder to the Dock so I can access it easier?

When you first buy a Mac, the right side of the Dock (the right side of the highway stripe on the Mac Dock) will have just the basic items on it, such as the Applications and Downloads folders. What a lot of people don't know is that you can put links (shortcuts) to your own folders there as well. In fact, this is a great place to put shortcuts to your most commonly used Mac folders.

Mac OS X Finder delete FAQ: How can I delete a file or directory in the Mac Finder using the keyboard (keystroke)?

By now you've probably figured out that you can't just delete a file in the Mac Finder using the delete key. The solution?

So, you're sitting there, looking at your Mac Finder window, and you see the file you need to work with, but wait ... what is the path to the directory you're looking at?

The Finder is a clever interface -- especially now that it sports four different views -- but at times like this, it just leaves you hanging. I run into this problem all the time when I go to upload a file using any of my web-based email clients, or when I upload a file using a web form.
