Hack the Tower and Adopt Openjdk - November 2014 hack day

hackthetower.co.uk is a hack day for any and all developers to come and collaborate on projects or discover new technologies together and enhance their skills.  Bring your laptop and your desire to learn & have fun!

Whether you want to build Java, Groovy, Scala, Force.com or Clojure apps, experiment with OpenJDK 8, get to grips with Git & Github, deploy apps with Heroku, try out one of the NoSQL databases like MongoDB or Neo4j or make some some robots dance, there are plenty of interesting things to work on.

We are also co-hosting the Adopt Openjdk hackday

Come hack on the Java implementation that you use everyday!

* Improved OpenJDK test coverage 
* OpenJDK Warnings cleanup 
* Small Bugs Fixes 
* The betterrev project

If you're not familiar with the OpenJDK codebase there will be people there to help you get started, including some from IBM who work on OpenJDK professionally.

Rough Schedule 

You can get into the offices from around 9.30am onwards and have some breakfast and coffee, relax and take in the stunning view from the 26th & 27th floors of the Salesforce Tower (formerly known as the Heron Tower).

10.30am - Get together and discuss application ideas & things you want to try out. 
10.45am - Split into groups and get going 
1pm - Lunch time (sandwiches, quiche, fruit and drinks provided, requests taken) 
1.30pm onwards - Keep on hacking until you have had enough or want to go to the pub!

    Awesome fun day. Thanks Mani for the insights and patience with the OpenJDK stuff (and my awful fisher price laptop).

    I managed to get it built at home on the desktop, and ran the regression tests.

    5 failures (but those are all because my ISP redirects failing lookups, so they're not an issue in jdk9, more an issue with the tests themselves being sensitive to my environment).

    Not sure why it decided to only run 3637 tests and didn't bother running 2578 of them. I daresay I'll discover that as I play with it more.

    Thanks for a good day.

    Hi, is there anyone who could see this message and let John that there are few people waiting downstairs? I'm afraid we are the sleepy ones ;-)

    *** My usual shout-out before we kick-off any Adopt OpenJDK hackdays! ***

    For those hacking away with the OpenJDK, as usual we have the beginners guide (Getting Started Kit - http://bit.ly/17ovGUB­­­). Have a look at the new section 'Known issues' to address some recent issues. If you have a problem log it with us, if you have solved any such problems let us know so we can add it to this document.

    For the intermediate and advance folks, we have the (Intermediate & Advance experiences - http://bit.ly/1ckphOl­­­). A number of new sections have been added from half-way through the document i.e. OpenJDK developers guide, list of JEPs, list of examples of tests, Visualisation of the OpenJDK codebase, etc... Plenty of reading this time before we start writing patches - see if any of the JEPs fancy your coding appetite.

    The intermediate and advanced (potential OpenJDK devs) developers can start looking at tests in the JDK repo and understanding and filling gaps in them.
