Codetown ::: a software developer's community
These days, it's hard to stick with just one language. Sure, you may be a Java developer or a Rubyist and "not interested" in learning another language. We tend to get comfortable in our comfort zone. But, being a polyglot has its advantages.
Tim Crowley just presented at SunJUG and Chris Schaefer was kind enough to circulate Tim's slides. I haven't spent much time on them yet, but being an iOS user and Android admirer, about to go from one to the other, and in light of the recent WWDC revelations, I am sure going to read these slides with passion. Enjoy, and please comment to let us know what you think!
Codetown is a social network. It's got blogs, forums, groups, personal pages and more! You might think of Codetown as a funky camper van with lots of compartments for your stuff and a great multimedia system, too! Best of all, Codetown has room for all of your friends.
