CS101: Algorithms

First in this series is the subject of Algorithms. This topic is very interesting to me because when I first strived to understand what exactly they were, I was expecting something a lot more complicated than what they turned out to be. I think, shamefully, that Hollywood may have had an influence on this, as the term “algorithm” is one of many terms abused by “cyber” movies and the like, portrayed to be some sort of ultimate cyber weapon in the war against Ellingson Mineral Company.

New Series: CS 101

Historically, my background is far closer to the systems side of things, but as I’ve picked up software development experience over the past few years, I’ve come to appreciate the fundamentals of computer science that others in my shoes may not have been exposed to. That said, I have been working on a pseudo-formal blog series on computer science fundamentals.

Introducing HTTP Testing in ToDD

Now that ToDD has been in the public arena for two months, one of the things I’m happiest about is the fact that testing in ToDD is totally flexible. Thanks to the concept of testlets, ToDD doesn’t have an opinion on the specifics of your tests - all of that logic is contained within the testlet.

Interop Vegas 2016

I’m happy to be given the opportunity to speak once more at Interop Vegas in 2016. No workshop for me this year, but I will be putting on three individual talks, all focusing on topics that have been very near and dear to me over the past year.

Next-Generation Network Telemetry

Late last year, I was pleased to be part of a special Tech Field Day event focused on network analytics. We had a day full of presentations from folks like Netflix, Google, and some goofball with a wrinkly jacket - all focused on what the next-generation networks will look like with respect to analytics.

The Power of Test-Driven Network Automation

Over the past few years, I’ve seen (and contributed to) a rise of real network engineers taking on the new and sometimes challenging world of network automation. Every time I check in on Jason Edelman’s Network Automation Slack channel, I’m very happy to see the sheer number of folks asking questions, trying to get the the concepts and tools of network automation working in their own environment.

The Unspoken Benefits of Open Networking

I have noticed a lot of very premature dismissal of a growing trend in the networking industry, which is the rise of open network operating systems. Nearly every post-announcement discussion that I hear among peers tends to sound something like this:

SDN and Network Automation: Splitting Hairs?

At the recent Network Field Day 11, there were several discussions at the Cisco offices after the Cisco folks left the room. One of these discussions, led by Terry Slattery, was centered around SDN, and I think it’s worth a listen/watch (only about 20 minutes):

2015 Recap and 2016 Goals

Wow, it’s that time of year again! 2015 went by really quickly, and a lot has changed for me. It’s also worth mentioning that this is the first year-end recap to be published on my new github pages site!

Training the Next-Generation Network Engineer

The networking industry is at a crossroads. In the past few years, we’ve seen a flurry of activity in the world of software-defined networking (SDN), but this has mostly just resulted in a bunch of new products. I don’t feel that this has done nearly enough to improve network operations. In fact, this has in many ways resulted in more complexity.
