User Discomfort As A Security Function

If you grew up in the 80s watching movies like me, you’ll remember Wargames. I could spend hours lauding this movie but for the purpose of this post I want to call out the sequence at the beginning when the two airmen are trying to operate the nuclear missile launch computer. It requires the use of two keys, one each in the possession of one of the airmen. They must be inserted into two different locks located more than ten feet from each other. The reason is that launching the missile requires two people to agree to do something at the same time. The two key scene appears in a number of movi ..read more

Repetition Without Repetition

I just finished spending a wonderful week at Cisco Live EMEA and getting to catch up with some of the best people in the industry. I got to chat with trainers like Orhan Ergun and David Bombal and see how they’re continuing to embrace the need for people in the networking community to gain knowledge and training. It also made me think about a concept I recently heard about that turns out to be a perfect analogy to my training philosophy even though it’s almost 70 years old. Practice Makes Perfect Repetition without repetition. The idea seems like a tautology at first. How can I repeat somethi ..read more

A Handy Acronym for Troubleshooting

While I may be getting further from my days of being an active IT troubleshooter it doesn’t mean that I can’t keep refining my technique. As I spend time looking back on my formative years of doing troubleshooting either from a desktop perspective or from a larger enterprise role I find that there were always a few things that were critical to understand about the issues I was facing. Sadly, getting that information out of people in the middle of a crisis wasn’t always super easy. I often ran into people that were very hard to communicate with during an outage or a big problem. Sometimes they ..read more

Painless Progress with My Ubiquiti Upgrade
The Networking Nerd

I’m not a wireless engineer by trade. I don’t have a lab of access points that I’m using to test the latest and greatest solutions. I leave that to my friends. I fall more in the camp of having a working wireless network that meets my needs and keeps my family from yelling at me when the network is down. Ubiquitous Usage For the last five years my house has been running on Ubiquiti gear. You may recall I did a review back in 2018 after having it up and running for a few months. Since then I’ve had no issues. In fact, the only problem I had was not with the gear but with the machine I installe ..read more

Back On Track in 2024

It’s time to look back at my year that was and figure out where this little train jumped off the rails. I’ll be the first to admit that I ran out of steam chugging along toward the end of the year. My writing output was way down for reasons I still can’t quite figure out. Everything has felt like a much bigger task to accomplish throughout the year. To that end, let’s look at what I wanted to do and how it came out: Keeping Track of Things: I did a little bit better with this one, aside from my post schedule. I tried to track things much more and understand deadlines and such. I didn’t alway ..read more

You’ve probably noticed that I haven’t been writing quite as much this year as I have in years past. I finally hit the wall that comes for all content creators. A combination of my job and the state of the industry meant that I found myself slipping off my self-appointed weekly posting schedule more and more often in 2023. In fact, there were several times I skipped a whole week to get put something out every other week, especially in the latter half of the year. I’ve always wanted to keep the content level high around here and give my audience things to think about. As the year wore on I fou ..read more

Routing Through the Forest of Trees

Some friends shared a Reddit post the other day that made me both shake my head and ponder the state of the networking industry. Here is the locked post for your viewing pleasure. It was locked because the comments were going to devolve into a mess eventually. The person making the comment seems to be honest and sincere in their approach to “layer 3 going away”. The post generated a lot of amusement from the networking side of IT about how this person doesn’t understand the basics but I think there’s a deeper issue going on.

Asking The Right Question About The Wireless Future
The Networking Nerd

It wasn’t that long ago that I wrote a piece about how Wi-Fi 6E isn’t going to move the needle very much in terms of connectivity. I stand by my convictions that the technology is just too new and doesn’t provide a great impetus to force users to upgrade or augment systems that are already deployed. Thankfully, someone at the recent Mobility Field Day 10 went and did a great job of summarizing some of my objections in a much simpler way. Thanks to Nick Swiatecki for this amazing presentation: He captured so many of my hesitations as he discussed the future of wireless connectivity. And he ma ..read more

AI Is Making Data Cost Too Much
The Networking Nerd

2M ago
You may recall that I wrote a piece almost six years ago comparing big data to nuclear power. Part of the purpose of that piece was to knock the wind out of the “data is oil” comparisons that were so popular. Today’s landscape is totally different now thanks to the shifts that the IT industry has undergone in the past few years. I now believe that AI is going to cause a massive amount of wealth transfer away from the AI companies and cause startup economics to shift. Can AI Really Work for Enterprises? In this episode of Packet Pushers, Greg Ferro and Brad Casemore debate a lot of topics arou ..read more
