After hearing such good things about it from my fossfolk friends over the years I'm delighted to be going to OSCON for the first time this year. Not only attending, but delivering a 3.5 hr tutorial on Inkscape. It's scheduled for 9am Monday 25 July.
Inkscape: Basic Tools and Techniques
You can read the abstract on the OSCON site. They've opened session abstracts for comments. This is a great way to generate dialogue between speaker and attendees before the event. I'm not sure how successful it will be, but I'm all up for giving it a red hot go. Drop me a line there if you're planning to attend my session. Let me know where you're at with Inkscape, and what you'd like to learn, and I may be able to customise my material for you in advance. Here's a quick screencast that show 4 different ways to draw a square.

Save 20% on OSCON Registration
Speaking of attending - O'Reilly have offered speakers a unique discount registration code - mine's not a hard secret to guess, it's Benjamin. If 5 people sign up for any package with my code, I'll get one free all access gold pass to the entire event to give to one lucky someone.
