Over the last couple of years, I have been slowly working on SubWars - a GPS based submarine game. I have had way too many fresh starts - new codebases, always some mix of Ruby, Smalltalk and MagLev. We just had our second little boy, and I now have even less time for side projects - so I’m open sourcing the project. I’ll be working on getting different parts / versions up over the next couple of months, but the first little part is now up at GitHub.
I am yet again starting with a fresh codebase, this time I am writing the entire client side in Amber. There’s not much there now, but its a start.
