Keith’s Law (1)

28 September 2021 | Comments Off on Keith’s Law (1)

I sometimes reference Keith’s Law in my teaching, but I don’t think I’ve ever explained it. Keith’s Law runs something like this:

Any large external step in a system’s capability is the result of many incremental changes within the system.

Leveraging Similarities

26 July 2021 | Comments Off on Leveraging Similarities

We tend to think every technology and every product is roughly unique—so we tend to stay up late at night looking at packet captures and learning how to configure each product individually, and chasing new ones as if they are the brightest new idea (or, in marketing terms, the best thing since sliced bread). Reality check: they aren’t. This applies across life, of course, but especially to technology.

Is it really the best just because its the most common?

24 May 2021 | Comments Off on Is it really the best just because its the most common?

I cannot count the number of times I’ve heard someone ask these two questions—

  • What are other people doing?
  • What is the best common practice?

While these questions have always bothered me, I could never really put my finger on why. I ran across a journal article recently that helped me understand a bit better. The root of the problem is this—what does best common mean, and how can following the best common produce a set of actions you can be confident will solve your problem?

New Video Course: How Networks Really Work

8 April 2021 | Comments Off on New Video Course: How Networks Really Work

Those who follow my work know I’ve been focused on building live webinars for the last year or two, but I am still creating pre-recorded material for Pearson. The latest is built from several live webinars which I no longer give; I’ve updated the material and turned them into a seven-hour course called How Networks Really Work. Although I begin here with the “four things,” the focus is on a problem/solution view of routed control planes.

Time and Mind Savers: RSS Feeds

5 April 2021 |

I began writing this post just to remind readers this blog does have a number of RSS feeds—but then I thought … well, I probably need to explain why that piece of information is important.

The amount of writing, video, and audio being thrown at the average person today is astounding—so much so that, according to a lot of research, most people in the digital world have resorted to relying on social media as their primary source of news. Why do most people get their news from social media? I’m pretty convinced this is largely a matter of “it saves time.” The resulting feed might not be “perfect,” but it’s “close enough,” and no-one wants to spend time seeking out a wide variety of news sources so they will be better informed.

The Hedge 76: Federico Lucifredi and the Taxonomy of Indecision

24 March 2021 |

Decision making, especially in large organizations, fails in many interesting ways. Understanding these failure modes can help us cope with seemingly difficult situations, and learn how to make decisions better. On this episode of the Hedge, Frederico Lucifredi, Ethan Banks, and Russ White discuss Frederico’s thoughts on developing a taxonomy of indecision. You can find his presentation on this topic here.

Slow Learning and Range

22 March 2021 |

Jack of all trades, master of none.

This singular saying—a misquote of Benjamin Franklin (more on this in a moment)—is the defining statement of our time. An alternative form might be the fox knows many small things, but the hedgehog knows one big thing.

The Hedge 71: Nick Russo and Automating Productivity

18 February 2021 | Comments Off on The Hedge 71: Nick Russo and Automating Productivity

When we think of automation—and more broadly tooling—we tend to think of automating the configuration, monitoring, and (possibly) the monitoring of a network. On the other hand, a friend once observed that when interviewing coders, the first thing he asked was about the tools they had developed and used for making themselves more efficient. This “self-tooling” process turns out to be important not just to be more efficient at work, but to use time more effectively in general. Join Nick Russo, Eyvonne Sharp, Tom Ammon, and Russ White as we discuss self-tooling.

Focus is a Virtue

25 January 2021 |

The modern world craves our attention—but only in short bursts. To give your attention to any one thing for too long is failing, it seems, because you might miss out on something else of interest. We have entered the long tail of the attention economy, grounded in finding every smaller slices of time in which the user’s attention can be captured and used.

The Hedge 67: Daniel Beveridge and the Structure of Innovation

20 January 2021 | Comments Off on The Hedge 67: Daniel Beveridge and the Structure of Innovation

Innovation and disruption are part the air we breath in the information technology world. But what is innovation, and how do we become innovators? When you see someone who has invented a lot of things, either shown in patents or standards or software, you might wonder how you can become an innovator, too. In this episode of the Hedge, Tom Ammon, Eyvonne Sharp, and Russ White talk to Daniel Beveridge about the structure of innovation—how to position yourself in a place where you can innovate, and how to launch innovation.
