Hedge 132: DNS Complexity and the DNAME

We all intuitively know the DNS is complex—and becoming more complex over time. Describing just how complex, however, is difficult. Siva Kesava and Ryan Beckett just published a research paper taking on the task of describing DNS complexity, particularly in light of the new DNAME record type. It turns out its complex enough that you can no longer really validate zone files.

Hedge 131: Easier for the Computer or the Person?

One of the mainstays of scripting—and now network management—are increasingly focused on making things “easier” for the human operator. Does this focus on making things “easier” for the operator produce a better experience, though? Or does it create frustration as humans try to “outguess” the computer’s programming and process? Join Tom Ammon and Russ White as they discuss the problems with scripting, automation, and ease-of-use.

Hedge 130: The Importance of Network Inventories

Inventories are generally hard, and hence don’t tend to be where you’d like to spend your time. The importance of having a good inventory, however, can hardly be overstated. Malcom Booden joins Tom Ammon and Russ White to talk about the importance of inventories and inventory ideas.

Hedge 129: Open Source Mentoring

Mentoring is a topic we return to time and again—because it’s one of the most important things we can talk about in terms of building your people skills, your knowledge, and your career. On this episode of the Hedge, Guedis Cardenas joins Tom Ammon and Russ White to talk about open source mentoring. We discuss how this is different than “regular” mentoring, and how it’s the same. Join us as we talk about one of the most important career and personal growth things you can do.

Hedge 128: Network Engineering at College

Have you ever thought about getting a college degree in computer networking? What are the tradeoffs between this and getting a certification? What is the state of network engineering at colleges—what do current students in network engineering programs think about their programs, and what they wish was there that isn’t? Rick Graziani joins Tom Ammon and Russ White in a broad ranging discussion on network engineering and college. Rick teaches network engineering full time in the Valley.

Hedge 127: FR Routing Update

The FR Routing project is a fully featured open-source routing stack, including BGP, OSPF, and IS-Is (among others), supported by a community including NVDIA, Orange, VMWare, and many others. On today’s episode of the Hedge, Tom Ammon and Russ White are joined by Donald Sharp, Alistair Woodman, and Quentin Young to update listeners on projects completed and underway in FR Routing.
