10 Scala One Liners to Impress Your Friends

Here are 10 one-liners which show the power of scala programming, impress your friends and woo women; ok, maybe not. However, these one liners are a good set of examples using functional programming and scala syntax you may not be familiar with. I feel there is no better way to learn than to see real examples.

Updated: June 17, 2011 - I'm amazed at the popularity of this post, glad everyone enjoyed it and to see it duplicated across so many languages. I've included some of the suggestions to shorten up some of my scala examples. Some I intentionally left longer as a way for explaining / understanding what the functions were doing, not necessarily to produce the shortest possible code; so I'll include both.

1. Multiple Each Item in a List by 2

The map function takes each element in the list and applies it to the corresponding function. In this example, we take each element and multiply it by 2. This will return a list of equivalent size, compare to o

Remote Debian Installation with Encrypted RootFS

This is a quick run-down of how I installed Debian on my dedicated server (@ OVH - super cheap!), and managed to setup an encrypted rootfs with ssh during boot to unlock. This is both for the offchance that I'll have to do it again, and if anyone else is wanting to do the same thing. There are a few guides out there to get the unlocking over SSH, and a few for remote installation of Debian, but none that combine the two.

These instructions need an existing Debian install, although Ubuntu might work too.
