Code Camp 6 is Oct 21-22 in Waltham.

You can register now.

You can also submit abstracts. Code Camp is a great place to show off anything from stuff you've figured out that you want to share or technologies that fascinate you that you were looking for an excuse to dig into. Session range from low-key "chalk talks" in front of small groups, to presentations in one of the larger rooms.

There will be 7 tracks so almost anything goes.

So... even if you have never presented before, this is a great and low-stress venue to share what you've learned with other developers.
