Cross Training for Career Completeness

Are you good at your job? Have you spent thousands of hours training to be the best at a particular discipline? Can you configure things with your eyes closed and are finally on top of the world? What happens next? Where do you go if things change?

It sounds like an age-old career question. You’ve mastered a role. You’ve learned all there is to learn. What more can you do? It’s not something specific to technology either. One of my favorite stories about this struggle comes from the iconic martial artist Bruce Lee. He spent his formative years becoming an expert at Wing Chun and no one would argue he wasn’t one of the best. As the story goes, in 1967 he engaged in a sparring match with a practitioner of a different art and, although he won, he was exhausted and thought things had gone on far too long. This is what encouraged him to develop Jeet Kun Do as a way to incorporate new styles together for more efficiency and eventually led to the development of mixed martial arts (MMA).

What does Bruce Lee have to do with tech? The value of cross training with different tech disciplines Continue reading

My Belated Review of Cisco Live 2023

It’s been a couple of weeks since Cisco Live US 2023 and I’m just now getting around to writing about it. I was thrilled to attend my 18th Cisco Live and it was just the thing I needed to reconnect with the community. The landscape of Cisco Live looks a little different than it has in years past. There are some challenges that are rising that need to be studied and understood before they become bigger than the event itself.

Showstopping Reveals? Or Consistent Improvement?

What was the big announcement from Cisco this year? What was the thing that was said on stage that stopped the presses and got people chattering? Was it a switch? A firewall? Was it a revolutionary new AI platform? Or a stable IP connection to Mars? Do you even know? Or was it more of a discussion of general topics with some technologies brought up alongside them?

In the last few years you may have noticed that the number of huge big announcements coinciding with the big yearly conferences has come down a bit. Rather than having some big news drop the morning of the keynote the big reveals are being given their own time Continue reading

Using AI for Attack Attribution

While I was hanging out at Cisco Live last week, I had a fun conversation with someone about the use of AI in security. We’ve seen a lot of companies jump in to add AI-enabled services to their platforms and offerings. I’m not going to spend time debating the merits of it or trying to argue for AI versus machine learning (ML). What I do want to talk about is something that I feel might be a little overlooked when it comes to using AI in security research.

Whodunnit?

After a big breach notification or a report that something has been exposed there are two separate races that start. The most visible is the one to patch the exploit and contain the damage. Figure out what’s broken and fix it so there’s no more threat of attack. The other race involves figuring out who is responsible for causing the issue.

Attribution is something that security researchers value highly in the post-mortem of an attack. If the attack is the first of its kind the researchers want to know who caused it. They want to see if the attackers are someone new on the scene that have developed new tools and Continue reading

Time Is Not On Your Side

It’s been almost five years since I wrote about the challenges of project management and timing your work as an engineer. While most of that information is still very true even today I’ve recently had my own challenges with my son’s Eagle Scout project. He is of a mind that you can throw together a plan and just do a whole week of work in just a couple of days. I, having worked in the IT industry for years, have assured him that it absolutely doesn’t work like that. Why is there a disconnect between us? And how does that disconnect look to the rest of the world?

Time Taking You

The first problem that I often see when working with people that aren’t familiar with projects is that they vastly underestimate the amount of time it takes to get something done. You may recall from my last post that my project managers at my old VAR job had built in something they called Tom Time to every quote. That provided a way for my estimate to reflect reality once I arrived on site and found the things didn’t go according to plan.

Part of the reason why my estimates Continue reading

Aruba Isn’t A Wireless Company (Any More)

Remember when Aruba was a wireless company? I know it sounds like something that happened 40 years ago but the idea that Aruba only really made wireless access points and some campus switches to support them isn’t as old as you think. The company, now known as HPE Aruba Networking (née Aruba, a Hewlett Packard Enterprise Company), makes more than just Wi-Fi gear. Yet the perception of the industry is that they’re still a wireless company looking to compete with the largest parts of the market.

Branching Out of Office

This year’s Aruba Atmopshere showed me that Aruba is trying to do more than just campus wireless. The industry has shifted away from just providing edge connectivity and is now focused on a holistic lineup of products that are user-focused. You don’t need to go much further than the technical keynote on the second day of the conference to see that. Or the Networking Field Day Experience videos linked above.

Do you know what Aruba wanted to showcase?

• Campus Switches
• Data Center Switches
• Private 5G/LTE
• SASE/SSE
• IoT
• Cloud-Enabled Management

You know what wasn’t on that list? Access points. For a “wireless” company that’s a pretty glaring omission, right? I think Continue reading

The Shifting Lens of Mentoring

The other day I realized that I had become the “old man” at Tech Field Day. Not so much that I’m ready for AARP but more that I’ve been there longer than anyone else but Stephen. The realization was a long time coming but the thing that pushed me to understand it was when someone asked a question about a policy we had and I not only knew the reason why we did it but also a time before we had it.

As I spent time thinking about the way that I’ve graduated from being the new guy to the old mentor I thought about the inflection point when the changeover happened.

Green and Growing

The first part of the demarcation between mentor and mentee in my eyes is where the knowledge lies. When you’re first starting out you’re the one that needs to understand things. You ask lots and lots of questions and try to understand how things are done and why you do them that way. Focusing on that knowledge acquisition is part of the marker of someone in need of mentorship.

For those trying to mentor these eager employees don’t make the mistake of getting frustrated at Continue reading

Mastodon Needs More Brand Support

As much as I want to move over to Mastodon full time, there’s one thing I feel that is massively holding it back. Yes, you can laud the big things about federations and freedom as much as you want. However, one thing I’ve seen hanging out in the fringes of the Fediverse that will ultimately hold Mastodon back is the hostility toward brands.

Welcoming The Crowd

If you’re already up in arms because of that opening, ask yourself why. What is it about a brand that has you upset? Don’t they have the same right to share on the platform as the rest of us? I will admit that not every person on Mastodon has this outward hostility toward companies. However I can also sense this feeling that brands don’t belong.

It reminds me a lot of the thinly veiled distaste for companies that some Linux proponents have. The “get your dirty binary drivers out of my pristine kernel” crowd. The ones that want the brands to bend to their will and only do things the way they want. If you can’t provide us the drivers and software for free with full code support for us to hack as much Continue reading

Consuming Content the Way You Want

One of the true hidden gems of being a part of a big community is the ability to discuss ideas and see different perspectives. It’s one of the reasons why I enjoy working at Tech Field Day and why I’m lamenting the death spiral of Twitter. My move to Mastodon is picking up steam and I’m slowly replicating the way that I consume content and interact there but it’s very much the same way I felt about Twitter thirteen years ago. There’s promise but it needs work.

As I thought about my journey with social media and discussed it with people in the community I realized that a large part of what has me so frustrated is the way in which my experience has been co-opted into a kind of performative mess. Social media is becoming less about idea exchange and more about broadcast.

Give and Take

When I first started out on Twitter I could post things that were interesting to me. I could craft the way I posted those short updates. Did I want to be factual and dry? Or should I be more humorous and snarky? I crafted my own voice as I shared with others. My Continue reading

Perfection Paralysis

This is a sort of companion piece to my post last week because I saw a very short post here about doing less. It really hit home with me because I’m just as bad as Shawn about wanting everything to be perfect when I write it or create it.

Maximizing Mistakes

One of the things that I’ve noticed in a lot of content that I’ve been consuming recently is the inclusion of mistakes. When you’re writing you have ample access to a backspace key so typos shouldn’t exist (and autocorrect can bugger off). But in video and audio content you can often make a mistake and not even realize it. Flubbing a word or needed to do a retake for something happens quite often, even if you never see or hear them.

What has me curious and a bit interested is that more of those quick errors are making it in. These are things that could easily be fixed in post production and yet they stay. It’s almost like the creators are admitting that mistakes happen and it’s hard to read scripts perfectly every time like some kind of robot. Honest mistakes over things like pronunciation or difficult word combinations Continue reading

Content Creation Complications

If you’ve noticed my regular blog posts have been a bit irregular as of late you’re not alone. I’m honestly working through a bit of writer’s block as of late. The irony is that I’m not running out of things to talk about. I’m actually running out of time to talk about them the way that I want.

Putting in the Work

By now you, my dear readers, know that I’m not going to put out a post of 200-300 words just to put something out during the week. I’d rather spend some time looking into a topic and creating something that informs or encourages discussion. That means having sources or doing research.

Research takes time. Ironically enough I’ve always had a much easier time writing things so long as I have the info to pull from in my head. One of the side effects of neurodivergence that I’ve learned about recently is that neurodivergent people tend to write their ‘first draft’ in their head throughout the creation process. Rather than writing and rewriting over and over again I pool all the information in my brain and work through it all to put down my final thoughts. That means what Continue reading

Assume Disaster

One of the things that people have mentioned to me in the past regarding my event management skills is my reaction time. They say, “You are always on top of things when they go wrong. How do you do it?”

My response never fails to make them laugh. I offer, “I always assume something is going to go wrong. I may not know what it is but when it does happen I’m ready to fix it.”

That may sound like a cynical take on planning and operations but it’s served me well for many years. Why is it that things we spend so much time working on always seem to go off the rails?

Complexity Fails

Whether it’s an event or a network or even a carpentry project you have to assume that something is going to go wrong. Why? Because the more complex the project the more likely you are to hit a snag. Systems that build on themselves and require input to proceed are notorious for hitting blocks that cause the whole thing to snarl into a mess of missed timelines.

When I was in college studying project management I learned there’s even a term for Continue reading

The Dangers of Knowing Everything

By now I’m sure you’ve heard that the Internet is obsessed with ChatGPT. I’ve been watching from the sidelines as people find more and more uses for our current favorite large language model (LLM) toy. Why a toy and not a full-blown solution to all our ills? Because ChatGPT has one glaring flaw that I can see right now that belies its immaturity. ChatGPT knows everything. Or at least it thinks it does.

Unknown Unknowns

If I asked you the answer to a basic trivia question you could probably recall it quickly. Like “who was the first president of the United States?” These are answers we have memorized over the years to things we are expected to know. History, math, and even written communication has questions and answers like this. Even in an age of access to search engines we’re still expected to know basic things and have near-instant recall.

What if I asked you a trivia question you didn’t know the answer to? Like “what is the name of the metal cap at the end of a pencil?” You’d likely go look it up on a search engine or on some form of encyclopedia. You don’t know Continue reading

Friction as a Network Security Concept

I had the recent opportunity to record a podcast with Curtis Preston about security, data protection, and networking. I loved being a guest and we talked about quite a bit in the episode about how networking operates and how to address ransomware issues when they arise. I wanted to talk a bit more about some concepts here to help flesh out my advice as we talked about it.

Compromise is Inevitable

If there’s one thing I could say that would make everything make sense it’s this: you will be compromised. It’s not a question of if. You will have your data stolen or encrypted at some point. The question is really more about how much gets taken or how effectively attackers are able to penetrate your defenses before they get caught.

Defenses are designed to keep people out. But they also need to be designed to contain damage. Think about a ship on the ocean. Those giant bulkheads aren’t just there for looks. They’re designed to act as compartments to seal off areas in case of catastrophic damage. The ship doesn’t assume that it’s never going to have a leak. Instead, the designers created it in such a way as Continue reading

Why Do YOU Have To Do It?

One of the things that I’ve seen as a common thread among people in the industry as of late is the subject of burnout. Sure, burnout is a common topic no matter what year we’re in but a lot more of what I’m starting to hear about is self-inflicted burnout. Taking on too many projects, doing more than one job, and even having too many things going on outside of your specific role are all contributors to burnout. How can we keep that from happening?

Atlas and His Burden

For me, one of the biggest reasons why I find myself swimming in frustration is because I am very quick to volunteer to do things. In part it’s because I want to make sure the job is done correctly. In another part it’s because I want to be seen as someone that is always willing to get things done. Add in a dash of people pleasing and you can see how this spirals out of control. I’m sure you’ve even heard that as a career advice at some point. I’ve even railed against it many times on this blog.

How can you overcome the impulse to want to volunteer to do Continue reading

Why Aren’t There More Technical MBAs?

This weekend I was listening to the latest episode of the Art of Network Engineering podcast featuring Russ White. Russ is one of those guests that has a breadth of knowledge outside of technology that colors the way he looks at things in the realm of enterprise IT. Plus he’s a fun interview.

One of the questions he asked was around the idea of technical MBAs. For those that might not know, MBA stands for Masters of Business Administration, which is a post-graduate college business degree. An MBA is widely regarded as a way to put yourself on a track to be a manager for a company in some capacity. An MBA is punching a ticket to be a future CEO. Why does it seem like the number of MBAs coming out of prestigious business schools don’t have a technical background then?

Where the Action Is

I’m going to quote liberally from a book I’ve been reading called The Personal MBA by Josh Kaufman. In it, Kaufman lays out the reasoning behind using his book to study the principles behind the information given in MBA classes instead of spending $200,000 to go to a business school for two years for Continue reading

Multicasting Content in the Twilight of Social Media

During Cisco Live EMEA last week I had an interesting conversation with a few people at the show around social media and how the usage of the platforms appears to be changing thanks to decisions made by the smartest people in a given broom closet. With the acceleration of the demise of Twitter as a platform I couldn’t help but comment on the fact that social media is becoming less about conversation and more about broadcast, which seemed to catch some of the people in the conversation off guard.

Back and Forth

Ever since the beginning of my time on Twitter, I’ve seen the platform as conversational instead of content-focused. Perhaps that’s the reason why the idea of a tweet storm has irritated me so much over the past few years. Twitter is about talking to people. It’s about interacting with them and creating a conversation in the noise. Twitter allows us to connect to people and exchange ideas and viewpoints.

Contrast that with other platforms in the social media spectrum. Specifically I’m thinking of Youtube video or TikTok videos. These platforms are designed to create content and send it to a number of people to view. It’s multicasting content Continue reading

Monitoring Other People’s Problems

It’s Always the Network is a refrain that causes operations teams to shudder. No matter what your flavor of networking might be it’s always your fault. Even if the actual problem is DNS, a global BGP outage, or even some issue with the SaaS provider. Why do we always get blamed? And how can you prevent this from happening to you?

User Utopia

Users don’t know about the world outside of their devices. As soon as they click on something in a browser window they expect it to work. It’s a lot like ordering a package and having it delivered. It’s expected that the package arrives. You don’t concern yourself with the details of how it needs to be shipped, what routes it will take, and how factors that exist half a world away could cause disruptions to your schedule at home.

The network is the same to the users. If something doesn’t work with a website or a remote application it must be the “network” that is at fault. Because your users believe that everything not inside of their computer is the network. Networking is the way that stuff happens everywhere else. As professionals we know the differences between Continue reading

Being the Best at Beginning

The other day I was listening to an excellent episode of The Art of Network Engineering talking about technical marketing engineers (TME). The discussion was excellent and there was one line from Pete Lumbis in the episode that stuck with me. He said that one of the things that makes you good as a TME is being an “expert beginner”. That phrase resonates at lot with me.

Fresh Eyes on the Problem

I talked a bit about this last year when I talked about being a beginner and how exciting that it was to start over with something. As I compared that post to the AONE episode I realized that what Pete was talking about was a shift in mindset that gives you the energy and focus to pick things up quickly.

You may have heard the phrase “familiarity breeds contempt”. It’s a common phrase used to describe how we feel less impressed with things the more we learn about then. Our brains are wired to enjoy new things. We love new experiences, going to new places, or even meeting new people. The excitement and rush that we get from something unfamiliar causes our brain to devour things. It’s only Continue reading

Friday Networking Field Day Thoughts

I’m wrapping up Networking Field Day 30 this week and as is always the case there was a lot of great discussion from both the presenters and the delegates outside of the presentations. It’s one of the reasons why I love doing this job even after almost ten years. I get to meet fun people and have an impact on so many things in the tech industry.

• Network-as-a-Service is coming. We recorded a roundtable discussion about it and I think the impact that it’s going to have on mid-sized businesses is massive. It’s going to be like cloud. Not just in operational capability. It’s also going to be a huge driver for what you can do with your network in support of applications. The snowflakes may melt under the weight of the cookies we make from the cookie cutter deployments.
• It feels like a lot of companies are trying to find what’s next. Part of that is coming from the ways that organizations are changing their outlook for what an office should be after the pandemic shutdowns. But still others are realizing they can’t use the same revenue stream for the next five years and hope to survive. This isn’t Continue reading

Controlling Your View of the World

Straw Bales on Hill Landscape, Tuscany, Italy

As I’m writing this it looks like Twitter has made some changes to the way that third-party clients interact with service. My favorite client, Tweetbot, is locked out right now. The situation is still developing but it’s not looking pretty for anyone using anything other than the web interface. While I will definitely miss the way I use Tweetbot I think it’s the kick I needed to move away from Twitter more than before.

A Window on the World

The apps that we use to consume and create content are the way that we view things. Maybe you prefer a webpage over an app or the way that one client displays things over another but your entire view is based on those preferences. If the way you consume your media changes your outlook on it changes too.

I didn’t always use Tweetbot to view Twitter. I tried using the standard app for a long time. It wasn’t until the infamous “Dickbar” incident back in 2011 that I broke away for something that wasn’t so slavishly dependent on ads. The trending topic bar might not have been specifically for ads at the time but Continue reading
