In this podcast, we’d like to introduce Dr Sam Bowne – Professor of Computer Networking and Information Technology from City College of San Francisco. Gordon and I have known or known of Sam since 2004. Sam is a tremendous classroom instructor bringing his extensive expertise in and passion for networking and network security to his students and his colleagues. Sam is also generous with his knowledge, making his lectures and classroom materials available to anyone who wants to learn. In what we hope will be a recurring role, Sam joins us today to share his thoughts on security and provide us with a snapshot of the latest and greatest developments in the field of network security.
Here's some of the questions Sam answers:
1. Sam you have a BS and a PhD in Physics – how did you end up in networking and security?
2. You’ve been at CCSF since 2000 – what classes do you teach?
3. Ethical hacking? Sounds like an oxymoron – what do you mean by ethical hacking?
4. I know you’ve taken some of your students to DEFCON in Las Vegas. This conference of hackers is probably unlike anything our listeners have ever attended. Could you tell us a little about it?
5. Are most of the attendees self-taught or do they attend formal classes?
6. In terms of recent developments (threats, security solutions, and research), what’s been on your radar screen lately?
7. Sam how do you keep up with all of this information?
8. What about your own skills and knowledge? How do you keep these up-to-date?
9. If a student is interested in learning more about networking – in particular securing a network, how would you advise them to get started? What sort of characteristics – in a student – would make them a good candidate for this type of work?
10. Now for something from a chat session with a student:
What advice can you give my studemt?

In our last podcast we discussed the past 20 years and how things have changed when it comes to broadband and cellular wireless service. In this podcast we provide an update on 4G services including LTE and WiMax.
Tue, 9 March 2010
In this podcast we take a look at the emergence of broadband and wireless technologies over the past 20 years.
Mike: What lead to this podcast?
Gordon: It was an email from a colleague of ours - Mark at the MATEC NSF center. Here’s what he said:
I was reading this PC Magazine article on why Apple stayed with AT&T (not happy about that since AT&T really stinks in Phoenix on coverage – if I remember correctly, one of the worst coverages and signals here. In fact, Sprint is really the only company that works well by the mountains (where I live and work). But the article stated:
CDMA, the way Verizon and Sprint are doing it, is a dead end. Apple hates dead-end technologies. They look forward, not back. Remember how they got rid of floppy disks earlier than any other PC manufacturer? The current CDMA technology that Sprint and Verizon use still has some years of life left on it, but it's not where wireless is heading.
Ok, so CDMA is dead. But what is 4G? And is all 4G using GSM? Sprint is starting to advertise here of their 4G network. I know 4G is faster. But where is wireless going? Is Sprint’s 4G the same as all the other’s 4G.
Ok, so hopefully this is a blog topic for you, but if not, I think you for the time on your answers. Oh yeah, any idea when AT&T would go to 4G?
Have a great day,
Mark from Arizona
Before we tried to answer Mark's questions we thought it would be a good idea to take a look first at where we’ve been over the past 20 years or so with a follow-up podcast on 4G technologies.

Leveraging Virtual Worlds, Web 2.0 and Smart Phones for Educational Excellence with Karl Kapp [45:09]
We had the honor of having Dr Karl Kapp keynote the second day of the Winter 2010 ICT Educator Conference held the first week of January in San Francisco. Karl is a professor of Instructional Technology, author, speaker and expert on the convergence of learning, technology and business. His background teaching e-learning classes, knowledge of adult learning theory and experience training CEOs and front line staff provides him with a unique perspective on organizational learning. Karl teaches graduate-level courses on topics of virtual learning worlds, e-learning applications and the business of e-learning at Bloomsburg University and consults with Fortune 500 organizations on implementing virtual learning worlds and learning technologies. He is author of four books including, Gadgets, Games and Gizmos for Learning and Learning in 3D: Adding a New Dimension to Enterprise Learning and Collaboration, co-authored with Tony O'Driscoll. Karl's keynote was delivered at the beautiful San Francisco Microsoft facility (Thanks Microsoft!) and titled Leveraging Virtual Worlds, Web 2.0 and Smart Phones for Educational Excellence. Here's a description of the presentation:
Are your classroom interactions designed to teach the new breed of learner - a learner raised on a steady diet of video games, electronic gadgets, and the Smartphones? Wondering how to integrate new technologies into your classroom? Can't imagine why anyone would want video games and Twitter in the classroom? Learn how the consumer-based gadgets, games and web widgets are changing community college education forever. The influence of games, virtual worlds and Web 2.0 on learning preferences, expectations and collaboration is just now becoming visible and is profoundly impacting community colleges. Learn how to leverage this technology for educational excellence. See examples of virtual worlds teaching science, iPods teaching basic chemistry, simulations teaching aircraft testing, and gadgets increasing student interactions in the classroom.
