This is *your* change to get up-to-date with Perl 6, specifically with Rakudo and NQP.
We have asked Jonathan Worthington to give an intensive 2-day workshop taking a deep dive into many areas of the Rakudo and NQP internals. Mostly focusing on the backend-agnostic parts but with coverage of the JVM and future MoarVM backends too. While the overall focus will be on getting to know the Rakudo and NQP internals, we'll also build the odd small language and object system along the way to get a better handle on the primitives. It will be held in Frankfurt am Main, Germany, on 14/15 September 2013, at: 7P B2B Mobile & IT Services GmbH Solmsstr. 4 60486 Frankfurt am Main http://goo.gl/maps/2T5j2 There are only 6 places left! Frankfurt is easily reachable by plane, train and car. Please contact me with questions, or show up on #perl6 (on irc.freenode.org) and let us know you're attending. Elizabeth Mattijsen Prerequisites ============= A reasonable knowledge of the Perl 6 language and, preferably, a little experience working with NQP also.
