Cutting to the Quick

No doubt you’ve seen the news that Intel has parted ways with Pat Gelsinger. There is a lot of info to unpack on that particular story but we did a good job of covering it on the Rundown this week. What I really wanted to talk about was a quote that I brought up in the episode that I heard from my friend Michael Bushong a couple of months ago:

No one cuts their way back into relevance.

It’s been rattling around in my head for a while and I wanted to talk about why he’s absolutely right.

Outcomes Need Incomes

Do you remember the coupon clipping craze of ten years ago? I think it started from some show on TLC about people that were ultra crazy couponers. They would do the math and they could buy like 100 lbs of rice for $2. They would stock up on a year’s worth of toothpaste at a time because you could pay next to nothing for it. However, the trend died out after a year or so. In part, that was because the show wasn’t very exciting after the shock of buying two years of hand soap wore off. The other Continue reading

AI Should Be Concise

One of the things that I’ve noticed about the rise of AI is that everything feels so wordy now. I’m sure it’s a byproduct of the popularity of ChatGPT and other LLMs that are designed for language. You’ve likely seen it too on websites that have paragraphs of text that feel unnecessary. Maybe you’re looking for an answer to a specific question. You could be trying to find a recipe or even a code block for a problem. What you find is a wall of text that feels pieced together by someone that doesn’t know how to write.

The Soul of Wit

I feel like the biggest issue with those overly word-filled answers comes down to the way that people feel about unnecessary exposition. AI is built to write things on a topic and fill out word count. Much like a student trying to pad out the page length for a required report, AI doesn’t know when to shut up. It specifically adds words that aren’t really required. I realize that there are modes of AI content creation that value being concise but those are the default.

I use AI quite a bit to summarize long articles, many of which Continue reading

Semper Gumby

By now I’m sure you’re familiar with Murphy’s Law: “Anything that can go wrong will go wrong.” If you work in IT or events or even in a trade you’ve seen things go upside down on many occasions. Did you ever ask yourself why this happens? Or even what you can do to fix it? What about avoiding it completely?

I have done a lot in IT over the years. I’ve also been working hard as an event planner and coordinator with Tech Field Day. The best lessons that I’ve learned about anticipating disaster have come from my time in Scouting. I’m often asked by companies “how did you know that would happen?” I almost always answer the same way: “I didn’t know THAT would go wrong, but I knew something would. I just kept my eye out for it.” It almost sounds too simple, right? But if you are familiar with event planning you know it’s almost a law, just like Mr. Murphy’s famous version.

How can you anticipate problems and still manage to make things happen? You can’t always fix everything. However, you can make sure that people don’t notice the issues. You just have Continue reading

Delegation And You

I once again loved this episode of the Art of Network Engineering featuring Mike Bushong. He is a very astute judge of character as well as how to apply social skills to your tech role. Definitely listen to the above episode if you’re interested in countering cognitive biases.

In the episode, he told a great story of how he had a pivotal career moment with one of his managers that led to some important introspection. I won’t tell his story but the summary is that he had taken on way too much work and way too many roles and he blew up at his manager because of the stress. She leveled him with a quote that rang true for me:

“No one knows everything you’re working on. They just see that the thing that’s important to them is late.”

That’s not the verbatim quote but that’s how I remember it. It’s definitely something that I’ve been thinking about since the previous episode when he mentioned it the first time.

Load Bearing and Busting

The odds are good that we’re all doing way too many things right now. Whether it’s doing more work in our role or taking on way Continue reading

Experience Expansion

Recently at Networking Field Day, one of the presenters for cPacket had a wonderful line that stuck with me:

There’s no compression algorithm for experience.

Like, floored. Because it hits at the heart of a couple of different things that are going on in the IT industry right now that showcase why it feels like everything is on the verge of falling apart and what we can do to help that.

Misteaks Hapin

Let’s just get this out of the way: you are going to screw up. Anyone doing any job ever for any amount of time has made a mistake. I know I’ve made my fair share of them over the years. When I finished chastising myself I looked back at what happened, figured out what went wrong, and made sure that it didn’t happen that exact same way again. That’s experience.

Experience is key to understanding why we do things the way we do them or why we don’t do something a certain way. You know how you get experience? By doing it. It’s rare that someone can read a book or a blog post about some topic and instantly know everything there is to know about Continue reading

The Keynote Answers You Expect

Good morning! How are you?

I’d like to talk about keynotes, again. You know, one of my favorite subjects. I’ve been watching them intently for the past few years just hoping that we’re going to see something different. As a technical analyst and practitioner I love to see and hear the details behind the technology that drive the way our IT companies develop. Yet every year I feel more and more disappointed by the way that keynotes take everything and push it into the stratosphere to get an 80,000 foot view of the technology. It’s almost like the keynotes aren’t written for practitioners. Why? The answer lies in the statement at the top of this post.

Perfunctory Performances

When most people ask someone how their day is going they’re not actually looking for a real response. They most certainly aren’t asking for details on how exactly the person’s day is going. They’re usually looking for one of two things:

1. It’s going great.
2. It could be better.

Any more than that drags someone down into a conversation that they don’t want to have. Asking someone about their day is a polite way of acknowledging them and making a bit of small Continue reading

The Legacy of Cisco Live

Legacy: Something transmitted by or received from an ancestor or predecessor or from the past. — Merriam-Webster

Cisco Live 2024 is in the books. I could recap all the announcements but that would take forever. You can find an AI that can summarize them for you much faster. That’s because AI was the largest aspect of what was discussed. Love it or hate it, AI has taken over the IT industry for the time being. More importantly it has also focused companies on the need to integrate AI functions into their product lines to avoid being left behind by upstarts.

That’s what you see in the headlines. Something I noticed while I was there was how the march of time has affected us all. After eighteen years I finally realized the sessions today have less in common with the ones I was attending back in 2010 than ever before. Development and advanced features configuration have replaced the tuning of routing protocols and CallManager deployment tips. It’s a game for younger engineers that have less to unlearn from the legacy technologies I’ve spent my career working on.

Leaving a Legacy

But legacy is a word with more than one definition. It’s Continue reading

Butchering AI

I once heard a quote that said, “The hardest part of being a butcher is knowing where to cut.” If you’ve ever eaten a cut of meat you know that the difference between a tender steak and a piece of meat that needs hours of tenderizing is just inches apart. Butchers train for years to be able to make the right cuts in the right pieces of meat with speed and precision. There’s even an excellent Medium article about the dying art of butchering.

One thing that struck me in that article is how the art of butchering relates to AI. Yes, I know it’s a bit corny and not an easy segue into a technical topic but that transition is about as subtle as the way AI has come crashing through the door to take over every facet of our lives. It used to be that AI was some sci-fi term we used to describe intelligence emerging in computer systems. Now, AI is optimizing my PC searches and helping with image editing and creation. It’s easy, right?

Except some of those things that AI promises to excel at doing are things that professionals have spent years honing their Continue reading

On Open Source and Volunteering

I saw a recent post on LinkedIn from Alex Henthorn-Iwane that gave me pause. He was talking about how nearly 2/3rds of Github projects are maintained by one or two people. He also quoted some statistics around how projects are maintained by volunteers and unpaid members as opposed to more institutional support from people getting paid to do the work. It made me reflect on my own volunteering journey and how the parallels between open source and other organizations aren’t so different after all.

A Hour A Week

Most of my readers know that one of my passion projects outside of Tech Field Day and this humble blog is the involvement of my children in Scouting. I spend a lot of my free time volunteering as a leader and organizer for various groups. I get to touch grass quite often. At least I do when I’m not stuck in meetings or approving paperwork.

One of the things that struck me in Alex’s post was how he talked about the lack of incoming talent to help with projects as older maintainers are aging out. We face a similar problem in scouting. Rather than our volunteers getting too old to do the Continue reading

Copilot Not Autopilot

I’ve noticed a trend recently with a lot of AI-related features being added to software. They’re being branded as “copilot” solutions. Yes, Microsoft Copilot was the first to use the name and the rest are just trying to jump in on the brand recognition, much like using “GPT” last year. The word “copilot” is so generic that it’s unlikely to be to be trademarked without adding more, like the company name or some other unique term. That made me wonder if the goal of using that term was simply to cash in on brand recognition or if there was more to it.

No Hands

Did you know that an airplane can land entirely unassisted? It’s true. It’s a feature commonly called Auto Land and it does exactly what it says. It uses the airports Instrument Landing System (ILS) to land automatically. Pilots rarely use it because of a variety of factors, including the need for minute last-minute adjustments during a very stressful part of the flight as well as the equipment requirements, such as a fairly modern ILS system. That doesn’t even mention that use of Auto Land snarls airport traffic because of the need to hold other planes outside Continue reading

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 movies as a way to show that so much power needs to have controls.

However, one thing I wanted to talk about in this post is the notion that those controls need to be visible to be effective. The two key solution is pretty visible. You carry a key with you but you can also see the locks that are situated apart from each other. There is a bit of challenge in getting the keys into the locks and turning them simultaneously. That not only shows that the Continue reading

Human Generated Questions About AI Assistants

I’ve taken a number of briefings in the last few months that all mention how companies are starting to get into AI by building an AI virtual assistant. In theory this is the easiest entry point into the technology. Your network already has a ton of information about usage patterns and trouble spots. Network operations and engineering teams have learned over the years to read that information and provide analysis and feedback.

If marketing is to be believed, no one in the modern world has time to learn how to read all that data. Instead, AI provides a natural language way to ask simple questions and have the system provide the data back to you with proper context. It will highlight areas of concern and help you grasp what’s going on. Only you don’t need to get a CCNA to get there. Or, more likely, it’s more useful for someone on the executive team to ask questions and get answers without the need to talk to the network team.

I have some questions that I always like to ask when companies start telling me about their new AI assistant that help me understand how it’s being built.

Question 1: Laying Continue reading

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 something without repeating it. I’m sure that the people in 1967 that picked up the book by Soviet neurophysiologist Nikolai Aleksandrovitsch Bernstein were just as confused. Why should you do things over and over again if not to get good at performing the task or learning the skill?

The key in this research from Bernstein lay in how the practice happens. In this particular case he looked at blacksmiths to see how they used hammers to strike the pieces they were working on. The most accurate of his test subjects didn’t just perform the Continue reading

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 were complicit because they made the mistake that caused it. They also bristled at the idea of someone else coming to fix something they couldn’t or wouldn’t. Just as often I ran into people that loved to give me lots of information that wasn’t relevant to the issue. Whether they were nervous talkers or just had a bad grasp on the situation it resulted in me having to sift through all that data to tease out the information I needed.

The Method

Today, as I look back on my career I would like Continue reading

Painless Progress with My Ubiquiti Upgrade

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 installed the controller software on. Turns out hard disk drives do eventually go bad and I needed to replace it and get everything up and running again. Which was my intention when it went down sometime in 2021. Of course, life being what it is I deprioritized the recovery of the system. I realized after more than a year that my wireless network hadn’t hiccuped once. Sure, I couldn’t make any changes to it but the joy of having a stable environment Continue reading

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 always succeed like I wanted to but at least I made the effort.
• Creating Evergreen Content: This one was probably a miss. I didn’t create nearly as much content this year as I have in years past. What little I did create sometimes felt unfocused and less impactful. Part of that has to do with the overall move away from written content to something more video and audio focused. However, even my other content like Tomversations was significantly reduced this year. I will Continue reading

Production Reductions

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 found myself running out of those ideas as portions of the industry slowed down. If other people aren’t getting excited about tech why should I? Sure, I could probably write about Wi-Fi 7 or SD-WAN or any number of topics over and over again but it’s harder to repeat yourself for an audience that takes a more critical eye to your writing than it is for someone that just wants to churn out material.

My Bruce Wayne job kept me busy this year. I’m proud of all the content Continue reading

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.

Trails To Nowhere

Our visibility of the state of the network below the application interface is very general in today’s world. That’s because things “just work” to borrow an overused phrase. Aside from the occasional troubleshooting exercise to find out why packets destined for Azure or AWS are failing along the way when is the last time you had to get really creative in finding a routing issue in someone else’s equipment? We spend more time now trying to figure out how to make our own networks operate efficiently and less time worrying about what happens to the packets when they leave our organization. Continue reading

Asking The Right Question About The Wireless Future

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 managed to expand on them perfectly!

New Isn’t Automatically Better

Any time I see someone telling me that Wi-Fi 7 is right around the corner and that we need to see what it brings I can’t help but laugh. There may be devices that have support for it right now, but as Nick points out in the above video, that’s only one part of the puzzle. We still have to wait for the clients and the regulatory bodies to catch up to the infrastructure technology. Could you imagine if we did the same Continue reading

AI Is Making Data Cost Too Much

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 around the future of networking. One of the things that Brad brought up that Greg pointed out is that data being used for AI algorithm training is being stored in the cloud. That massive amount of data is sitting there waiting to be used between training runs and it’s costing some AI startups a fortune in cloud costs.

AI algorithms need to be trained to be useful. When someone uses ChatGPT to write a term paper or ask nonsensical questions you’re using the output of the GPT training run. Continue reading
