Michael Natkin, over at Glowforge, writes: “That’s a funny thing about our minds. In the absence of information, they fill in the gaps and make up all sorts of plausible things, without the owners of said minds even realizing it is happening.” The answer, he says, is to overcommunicate. Michael joins Eyvonne Sharpe, Tom Ammon, and Russ White on this episode of the Hedge to discuss what it means to overcommunicate.
Many engineers have heard about the wide variety of Network Operator Group (NOG) meetings, from smaller regional organizations through larger multinational ones. What is the value of attending a NOG? How can you convince your business leadership of this value? In this episode of the Hedge Vincent Celindro and Edward McNair join Russ White to consider these questions.
In this episode of the Hedge, Ethan Banks, Ethan’s old-timey routers, Tom Ammon, Tom’s printer, Eyvonne Sharp, and Russ White sit around the virtual hedge to talk about networking fundamentals. What are they, why are they important, how you learn them, and how to be intentional about your career.
CHINOG is a regional network operators group that meets in Chicago once a year. For this episode of the Hedge, Jason Gooley joins us to talk about the origins of CHINOG, the challenges involved in running a small conference, some tips for those who would like to start a conference of this kind, and thoughts on the importance of community in the network engineering world.
Staring at the white line is fun at first, then mesmerizing, then it is frightening… then finally it is just plain dull. But let’s talk about the terrifying bit because it’s the scary stage that makes us all reject change out of fear for the future. And, trust me, a kid sitting in a car with no doors staring down at the white line while his uncle drives 60 miles-per-hour is going to be frightened from time to time.
If there is one thing I notice when I look around at the IETF—and many other places where I meet a lot of network operations and engineering folk—it’s that we all seem to be getting a bit older. This should lead us to an obvious question—what are we doing about bringing up a new generation of network engineers? David Huberman joins Tom Ammon and I to discuss this interesting question. David i s involved in a number of community-based efforts to train next generation network engineers, some of which he discusses in his excellent article at the APNIC blog.
This is the first of the ironies of automation Lisanne Bainbridge discusses—and this is the irony I’d like to explore. The irony she is articulating is this: the less you work on a system, the less likely you are to be able to control that system efficiently. Once a system is automated, however, you will not work on the system on a regular basis, but you will be required to take control of the system when the automated controller fails in some way. Ironically, in situations where the automated controller fails, the amount of control required to make things right again will be greater than in normal operation.
In the case of machine operation, it turns out that the human operator is required to control the machine in just the situations where the least amount of experience is available. This is analogous to the automated warehouse in which automated systems are used to stack and sort material. When the automated systems break down, there is absolutely no way for the humans involved to figure out why things are stacked the way they are, nor how to sort things out to get things running again.
According to Michael Natkin, “in the tech industry, with our motto of “strong opinions, loosely held” (also known as “strong opinions, weakly held”), we’ve glorified overconfidence.” Michael joins Tom Ammon and Russ White to discuss the culture of overconfidence, and how it impacts the field of information technology.
Network engineering and operations are both “mental work” that can largely be done remotely—but working remote is not only great in many ways, it is also often fraught with problems. In this episode of the Hedge, Roland Dobbins joins Tom and Russ to discuss the ins and outs of working remote, including some strategies we have found effective at removing many of the negative aspects.
Two things which seem to be universally true in the network engineering space right this moment. The first is that network engineers are convinced their jobs will not exist or there will only be network engineers “in the cloud” within the next five years. The second is a mad scramble to figure out how to add value to the business through the network. These two movements are, of course, mutually exclusive visions of the future. If there is absolutely no way to add value to a business through the network, then it only makes sense to outsource the whole mess to a utility-level provider.
The result, far too often, is for the folks working on the network to run around like they’ve been in the hot aisle so long that your hair is on fire. This result, however, somehow seems less than ideal.
