This was a little bit late. But I still value this video because this was my first presentation in other University. We conducted it on University of the Philippines, Diliman as part of Microsoft Student Partners' agenda to introduce and promote Microsoft Development tools and technologies like the one we've discussed (ASP.NET and AJAX). Athough not of all students/attendees are not so techie, the presentation worked smoothly. You can check the link of the video at My First Presentation Demo . It was fun and we enjoyed it from preparation up to the presentation although we are busy with schooling and work, overall, it was all paid off! 
Software Architecture was one of the field I want to discover. I always heard this in forums and other presentation or events conducted by different user group. And now, as a Software Developer, I want to share you guys this link which I have read a lot of times and ordered a lot of times. You can order for even 100 copies per issues and it will be delivered to you right at your doorstep by DHL. Although you will not be a Software Architect after reading those issues, but it will a good inspiration for you from the editor's pick, to the latest technology, from business to system development. It's a combination of practices from practitioners chosen by the editors of the journal. You will learned a lot from it, and I used to read this one on my way to work, and sometimes when I go home. I hope you'll have fun about it. Make it sure you give tips to the delivery guy because my Mom always scold me when I am not giving tips for appreciation.
