How to Install GraalVM Community Edition on Linux

Note: Tested on Fedora only

1. Download the new release of GraalVM and unpack it anywhere in your filesystem:

$ tar -xvzf graalvm-ce-1.0.0-rc14-linux-amd64.tar.gz

Some of these practices might be based on wrong assumptions and I'm not aware of it, so I would appreciate any feedback.

1. avoiding some dependency conflicts:

   • install sbt-explicit-dependencies globally in your ~/.sbt/{0.13,1.0}/plugins/plugins.sbt
   • run undeclaredCompileDependencies and make the obvious missing dependencies explicit by adding them to libraryDependencies of each sub-project
   • (optionally) run unusedCompileDependencies and remove some obvious unused libraries. This has false positives, so ; reload; Test/compile after each change and ultimately run all tests to see that it didn't break anything
   • (optionally) add undeclaredCompileDependenciesTest to the CI pipeline, so that it will fail if you have some undeclared dependencies

2. keeping dependencies up to date and resolving conflicts:

   • install sbt-updates globally in your `~/.sbt/{0.13,1.0}/plugins/plugins.

 * Golang has its very own serializer / deserializer - Go Object (gob) so why not use it where data passed is entirely within a Go

 *
 * JSON or some other text based solution could be used but gob might be faster.
 *
 * A gob encoder accepts the type bytes.Buffer to encode data to, so to write this to Badger, which accepts the type byte

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
