We're excited to introduce Hack, our new programming language for HHVM. We invite you to join the designers and engineers behind Hack and HHVM for an introductory Hack/HHVM Developer Day at Facebook HQ.

This is a small event, welcoming developers who want to participate in a dialogue on the development of these technologies.

The event will consist of two parts:

In the morning and afternoon, we'll give a series of talks about Hack and HHVM.

In the late afternoon and evening, we're running a Hackathon, in which you will be able to meet and work with the creators of Hack and HHVM.

We will serve snacks, lunch, and dinner.
