Who really broke Enigma?

October 16, 2012 at 8:28 am PST

Some of the best conversations happen in private exchanges and I often wish we could all benefit more broadly.  This most recent conversation was instructive in and of itself but it also pointed out a level of transparency both Jimmy Ray and I prefer.  So hopefully it goes to say -- we welcome your input! We certainly don’t get it right all the time!

Episode 119 featured Next Generation encryption and we mistakenly attributed Great Britain with breaking Enigma. One of our Cisco fans from Warsaw, Bartlomiej (Bartek) Michalowski, sent us a note.

Networking 101: Internet Cookies

September 24, 2012 at 4:39 am PST

Internet cookies seem to have the best name with a somewhat negative perception.  Its really not the cookie thats to blame. Most geeks will laugh that we even would consider this topic for a video but the fact remains, too many people misunderstand the value and besides, its part of the Networking 101 series..its supposed to be basic!

Networking 101: DNS Revealed

DNS is key to making the Internet accessible to us humans. It’s how we can connect to techwisetv.com without needing to know anything complex from anywhere in the world. How does it know how to do this? DNS can be a complicated topic but understanding the basics does not have to be.

Taking it a step further, DNSSEC is a suite of IETF specifications designed to guarantee the authenticity of data obtained from the domain name system (DNS). Although not designed for confidentiality of the data, this protocol is a great answer for many of the ills that threaten the simplicity of the Internet. Chief Geek Jimmy Ray Purser arms you with how it works and why deployment is not growing as fast as it should be.

Deploying the Mobility Services Engine

December 15, 2011 at 3:47 pm PST

CleanAir continues to provide significant differentiation for Cisco Wireless as well it should. What many don’t realize, is how much of the attractive visualization and control is not from CleanAir itself, but CleanAir plus the Mobility Services Engine. I would go as far as to say there are several very important distinctions for why the MSE should be considered a mandatory element within any Cisco Wireless Design.
