    All those participating in the Adopt OpenJDK sessions with Mike Burton - I would suggest have a look at this page ( and sign up to the respective forums including the iRC channel.

    ...Java9 Continued..
    To prepare before the day see which also has a link to "Quick Start Guide"
    These pages describes how to obtain Java source code, and also how to build Java if you want to, using an Ubuntu virtual machine (Or use Docker if you prefer).

    I'd like to explore new features in Java9 so we can form a group to hack on that for all who are interested.
    For newer Java devs I'll also bring some ideas from the LJC "Beginning Java" evening series.

    Hi all. What sort of level of experience/expertise is expected at these events? I was wondering whether it would be worth me encouraging some of the newer devs on our team to come along. However some hack days can feel a bit daunting if you're not someone who can churn out hundreds of LOC per hour.

    • John S.

      HackTheTower is a self-organising event, so there should not be any expectations. The overal aim is to encourage collaboration rather than churn out code.

      If you encorage members of your dev team to come along, you could suggest projects or technology that the could work on collaboratively. Or better still encorage them to think about what they would find most interesting & valuable to get involved with. What coding itches do they want to scratch?

      Hope that helps.
