Chuck Black


Chuck has been developing software for networking equipment since 1981 and has designed and developed software products for large scale networking environments using languages such as C, C++, and Java. 

Chuck has been granted 15 patents in the areas of network topology discovery, management, monitoring, health, and access control.

Chuck graduated from California Polytechnic State University-San Luis Obispo with Bachelor and Master of Computer Science degrees.

Chuck has developed Python for Network Engineers courses for vendors such as Cisco and Juniper Networks. In addition, he has developed numerous SDN application development courses for vendors such as Cisco, HPE and Brocade.

Chuck is the co-author of the book SDN: A Comprehensive Approach, a thorough technical and business exploration of software defined networking, which has been used as a textbook for graduate level computer science coursework.

Chuck is a well known figure in SDN and network programmability circles. He has made participated in organizations such as the Open Networking Foundation (ONF) and the OpenDaylight project.

Chuck is the coauthor of one of the most popular SDN books on the market today: Software Defined Networks: A Comprehensive Approach.

Hank Preston


Hank’s two passions are technology and theatre. Bringing them together drives him towards a borderline obsession on creating entertaining presentations, labs and demonstrations that breakdown complex technology topics for audiences. After spending several years working on and behind the scenes on stage productions, what started as a hobby turned to a profession when Hank entered the IT industry with a focus on web and database development and engineering. 

Drifting from development into infrastructure engineering brought him to Cisco as a Systems Engineer, focusing on Data Center and Cloud Architecture for large enterprise customers. 

And after six years as an SE, Hank took up the mantle of a Developer Evangelist with DevNet where he can focuses full time on reminding everyone that technology can and should be fun to work with. 

Hank holds a Master Degree in Information Systems as well as several certifications including CCIE R/S 38336 from Cisco.
