Innovation Myths

30 November 2020 | Comments Off on Innovation Myths

Innovation has gained a sort-of mystical aura in our world. Move fast and break stuff. We recognize and lionize innovators in just about every way possible. The result is a general attitude of innovate or die—if you cannot innovate, then you will not progress in your career or life. Maybe it’s time to take a step back and bust some of the innovation myths created by this near idolization of innovation.

You can’t innovate where you are. Reality: innovation is not tied to a particular place and time. “But I work for an enterprise that only uses vendor gear… Maybe if I worked for a vendor, or was deeply involved in open source…” Innovation isn’t just about building new products! You can innovate by designing a simpler network that meets business needs, or by working with your vendor on testing a potential new product. Ninety percent of innovation is just paying attention to problems, along with a sense of what is “too complex,” or where things might be easier.

Random Thoughts

28 September 2020 | Comments Off on Random Thoughts

This week is very busy for me, so rather than writing a single long, post, I’m throwing together some things that have been sitting in my pile to write about for a long while.

From Dalton Sweeny:

A physicist loses half the value of their physics knowledge in just four years whereas an English professor would take over 25 years to lose half the value of the knowledge they had at the beginning of their career. . . Software engineers with a traditional computer science background learn things that never expire with age: data structures, algorithms, compilers, distributed systems, etc. But most of us don’t work with these concepts directly. Abstractions and frameworks are built on top of these well studied ideas so we don’t have to get into the nitty-gritty details on the job (at least most of the time).

Enterprise and Service Provider—Once more into the Windmill

16 March 2020 | Comments Off on Enterprise and Service Provider—Once more into the Windmill

There is no enterprise, there is no service provider—there are problems, and there are solutions. I’m certain everyone reading this blog, or listening to my podcasts, or listening to a presentation I’ve given, or following along in some live training or book I’ve created, has heard me say this. I’m also certain almost everyone has heard the objections to my argument—that hyperscaler’s problems are not your problems, the technologies and solutions providers user are fundamentally different than what enterprises require.

Let me try to recap some of the arguments I’ve heard used against my assertion.

The Hedge 26: Jason Gooley and CHINOG

11 March 2020 | Comments Off on The Hedge 26: Jason Gooley and CHINOG

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.

Too Little Engineering

3 February 2020 | Comments Off on Too Little Engineering

One of my pet peeves about the network “engineering” world is this: we do too little engineering and too much administration. What brought this to mind this week is an article about Margaret Hamilton about the time she spent working on software development for the Apollo space program, and the lessons she learned about software development there. To wit—

Engineering—back in 1969 as well as here in 2020—carries a whole set of associated values with it, and one of the most important is the necessity of proofing for disaster before human usage. You don’t “fail fast” when building a bridge: You ensure the bridge works first.

Sounds simple in theory—but it is not in practice.

Let’s take, as an example, replacing some of the capacity in your data center designed on a rather traditional two-layer hierarchy, aggregation, and core.

The Hedge 13: Ivan Pepelnjak

19 November 2019 | Comments Off on The Hedge 13: Ivan Pepelnjak

In this episode of the Hedge, Tom Ammon and Russ White are joined by Ivan Pepelnjak of ipSpace.net to talk about being old, knowing about how things are going to break before they do, and being negative. Along the way, we discuss the IETF, open source, and many other aspects of the world of network engineering.

The Hedge 11: Roland Dobbins on Working Remotely

6 November 2019 | Comments Off on The Hedge 11: Roland Dobbins on Working Remotely

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.

(Effective) Habits of the Network Expert

14 October 2019 |

For any field of study, there are some mental habits that will make you an expert over time. Whether you are an infrastructure architect, a network designer, or a network reliability engineer, what are the habits of mind those involved in the building and operation of networks follow that mark out expertise?

Experts involve the user

Experts don’t just listen to the user, they involve the user. This means taking the time to teach the developer or application owner how their applications interact with the network, showing them how their applications either simplify or complicate the network, and the impact of these decisions on the overall network.

Experts think about data

Rather than applications. What does the data look like? How does the business use the data? Where does the data need to be, when does it need to be there, how often does it need to go, and what is the cost of moving it? What might be in the data that can be harmful? How can I protect the data while at rest and in flight?

The Hedge 9: Nash King and Ethics in IT

8 October 2019 | Comments Off on The Hedge 9: Nash King and Ethics in IT

Nash King (@gammacapricorni) joins Russ White and Tom Ammon in a wide ranging discussion of ethics in IT, including being comfortable with standing up and saying “no” when asked to do something you consider unethical and the virtue ethic. This is meant to be the first of a series of episodes on this topic.
