Lovelace is a training website for the Australian Informatics Olympiad programme, backwards-compatible with judge and the old database layer.

You will need:

• Git (tutorials: 1, 2)
• The Scala build tool
• Java (in theory, either Oracle Java or OpenJDK will work).

To compile, from the root of your project, type:

sbt compile

You may see messages like this the first time you compile:

Getting org.scala-sbt sbt 0.13.9 ...
[info] Resolving org.scala-lang#scala-compiler;2.11.7 ...

This is sbt fetching a specific version of itself and the Scala compiler (read: reproducible builds). It may look like it's hanging, but actually be downloading at the impressive bandwidth of 3Kb/s. This should only need to happen once. Grab a coffee; make a Java pun.

To compile-and-run, type:

sbt run

By default, this should open an instance on port 8080.
