I'm sitting here at the keynote for CFUnited 2008 and wanted to post a quick reminder to all the super talented speakers to make sure you post your presentations to the CFUnited 2008 group at SlideSix.com. That way everyone who couldn't make it to the conference can check out your wonderful presentations! Don't forget you can even attach a zip containing your code samples or other supporting material directly within your presentation on the site!

I'm officially heading out to begin my journey to CFUnited 2008. We have an overnight stay at my in-laws along the Ohio/Pennsylvania border and then it's off to DC early tomorrow morning. Leave a comment if you're coming into town a day or two early and we'll try to hook up. If not I'll see everyone Tuesday night/Wednesday. Looking forward to some good networking and lots of learning!

Wow, this one really boggles my feeble mind. Found an issue where session variables do not persist when browsing in an IFRAME on IE. I Googled it and amazingly found the solution here. Basically you just add: And they magically work. Anyone know what the hell that does?

I pushed some changes last night to SlideSix.com to enable SES URL's. I used IIRF, a free URL rewriting filter for the URLs, and so far it seems to be working out pretty well. Nothing terribly interesting to most users I'd say, but I wanted to put the word out to all of my friends in case you come acrossed a glitch with the URL's. If you do, please let me know. The cool part is that you can now share a friendly URL with everyone you know.

After talking about it for four years, Ray Camden has finally launched the rebuilt version of CFLib. Congrats Ray! The new site looks fantastic and is speedier then ever. Everyone attending CFUnited that uses CFLib is now required to buy Ray a beer (imported only please).

Just a quick update to add the default roles and question types that should have shipped with version 1.8 (they have been added to the end of the /install/ilearn_install.sql script) and a quick feature addition. You can now create 'news' announcements from within the admin. Some other minor modifications were added too - minor CSS things, etc. Thanks to Thomas Messier for pointing out that I didn't ship the roles and question types. Download iLearn at RIAForge.

I've just released iLearn which is a simple Learning Management System built in ColdFusion. With iLearn you simply input your users into the system (admin users, instructors and students). Once instructors and students have been built into the system you can build courses. After a course is built you associcate exams, questions and answers. When an exam is issued, students can take the exams.

Liz posted some questions for CFUnited 2008 attendees. Here are my answers. What are you looking forward to most? Seeing my friends. It is really great to get the chance to catch up with everyone in the CF Community. It never ceases to amaze me how brilliant most of the people in our community are. I always leave feeling humbled about my own skills! I'm also looking forward to picking up some knowledge at the sessions, but the networking is really what it's all about for me.

I just pushed a quick change up for SlideSix.com to allow for ZIP attachments (up to 1mb) to your SlideCasts. I also updated my CF.Objective SlideCast to include my code samples used during that presentation. Click the paper clip on any SlideCast to view/download attachments. It's usually easier to see on fullscreen preso's (like this one). On embedded preso's the paperclip is hidden when the control panel is collapsed - so to see the attachments you have to expand the nav/control panel.

The other day my buddy Ray suggested that I allow attachments to presentations on SlideSix. I thought it was a great idea, but when I checked the docs for <cfpresentation> I was surprised to find that the tag did not support attachments out of the box. However, after a bit of hackery I found a way to do it. When you create a preso with cfpresentation and write it to disk there is a subdirectory created called 'data'.
