Andrew Oliver (http://www.infoworld.com/author-bios/andrew-c-oliver) is working on an Infoworld article whose premise is that given your proficiency in programming language X you should be able to implement something in programming language Y fairly easily. To that effect we're trying to implement a simple address book application with a PostgreSQL database and an AJAXy HTML frontend using Kotlin in a day. We were wondering if we could get a mentor for a day to help with this project.
I'm will more than happy to operate in your timezone. What time do you normally start your day? It might not take very long. I've looked at the Kara framework that help create a simple Web application. I would need help talking to the Postgres database and communicating with the Front-end in JSON.
We'll just see how it goes. What database have you tested your jdbc support with? If we face issues we could just switch to an in memory database or something else. We're doing this project with other languages as well, none of which are as new as Kotlin and we picked Postgres as the database to be consistent. But it wouldn't be so bad if we get it working with something else.
