Slow and Steady and Complete

StepTiles

I was saddened to learn last week that one of my former coworkers passed away unexpectedly. Duane Mersman started at the same time I did at United Systems and we both spent most of our time in the engineering area working on projects. We worked together on so many things that I honestly couldn’t keep count of them if I tried. He’s going to be missed by so many people.

A Hare’s Breadth

Duane was, in many ways, my polar opposite at work. I was the hard-charging young buck that wanted to learn everything there was to know about stuff in about a week and just get my hands dirty trying to break it and learn from my mistakes. If you needed someone to install a phone system next week with zero formal training or learn how iSCSI was supposed to operate based on notes sketched on the back of a cocktail napkin I was your nerd. That meant we could often get things running quickly. It also meant I spent a lot of time trying to figure out why things weren’t working. I left quite a few forehead-shaped dents in data center walls.

Duane was not any of those Continue reading

Follow My Leader

I spent the past two weeks enjoying the scenic views at the Philmont Scout Ranch with my son and some of his fellow Scouts BSA troop mates. It was very much the kind of vacation that involved a lot of hiking, mountain climbing, and even some inclement weather. We all completely enjoyed ourselves and I learned a lot about hanging bear bags and taking care of blisters. I also learned a lot about leadership by watching the boys in the crew interact with each other.

Storm Warnings

Leadership styles are nothing new to the people that read my blog. I’ve talked about them at length in the past. One thing I noticed when I was on the trek was how different leadership styles can clash and create friction among teenagers. As adults we tend to gloss over delivery and just accept that people are the way they are. When you’re fourteen or fifteen you haven’t quite taken that lesson to heart yet. That means more pushing against styles that don’t work for you.

We have all worked for or with someone that has a very authoritarian style in the past. The kind of people that say, “Do this right now” Continue reading

Pegasus Pisses Me Off

UnicornPegasus

In this week’s episode of the Gestalt IT Rundown, I jumped on my soapbox a bit regarding the latest Pegasus exploit. If you’re not familiar with Pegasus you should catch up with the latest news.

Pegasus is a toolkit designed by NSO Group from Israel. It’s designed for counterterrorism investigations. It’s essentially a piece of malware that can be dropped on a mobile phone through a series of unpatched exploits that allows you to create records of text messages, photos, and phone calls and send them to a location for analysis. On the surface it sounds like a tool that could be used to covertly gather intelligence on someone of interest and ensure that they’re known to law enforcement agencies so they can be stopped in the event of some kind of criminal activity.

Letting the Horses Out

If that’s where Pegasus stopped, I’d probably not care one way or the other. A tool used by law enforcement to figure out how to stop things that are tough to defend against. But because you’re reading this post you know that’s not where it stopped. Pegasus wasn’t merely a tool developed by intelligence agencies for targeted use. If I had to Continue reading

Should We Embrace Points of Failure?

failure-pic-1

There was a tweet making the rounds this last week that gave me pause. Max Clark said that we should embrace single points of failure in the network. His post was an impassioned plea to networking rock stars out there to drop redundancy out of their networks and instead embrace these Single Points of Failure (SPoF). The main points Mr. Clark made boil down to a couple of major statements:

  1. Single-device networks are less complex and easier to manage and troubleshoot. Don’t have multiple devices when an all-in-one works better.
  2. Consumer-grade hardware is cheaper and easier to understand, therefore it’s better. Plus, if you need a backup you can just buy a second one and keep it on the shelf.

I’m sure more networking pros out there are practically bristling at these suggestions. Others may read through the original tweet and think this was a tongue-in-cheek post. Let’s look at the argument logically and understand why this has some merit but is ultimately flawed.

Missing Minutes Matter

I’m going to tackle the second point first. The idea that you can use cheaper gear and have cold standby equipment just sitting on the shelf is one that I’ve heard of many Continue reading

VARs See You As Technical Debt

I’ve worked for a Value Added Reseller (VAR) in the past and it was a good run of my career before I started working at Tech Field Day. The market was already changing eight years ago when I got out of the game. With the advent of the pandemic that’s especially true today. Quite a few of my friends say they’re feeling the pressure from their VAR employer to stretch beyond what they’re accustomed to doing or outright being treated in such a way as to be forced out or leaving on their own. They tell me they can’t quite understand why that’s happening. After some thought on the matter I think I know. Because you represent debt they need to retire.

Skill Up

We don’t start our careers knowing everything we need to know to make it. The industry spends a lot of time talking about careers and skill paths and getting your legs under you. Networking people need to learn Cisco or Juniper or whatever configuration language makes the most sense for them. Wireless people need to learn how to do site surveys and configure access points. Server people need to learn operating systems and hypervisors. We start Continue reading

Friday Thoughts on Going Back To the Office

EmptyOffice

We’re halfway through 2021 and it’s been going better than last year. Technology seems to be rebounding and we’re seeing companies trying to find ways to get employees to come back into the office. Of course, that is being met head on by the desire to not go back at all and continue to do the job from home that has been done over the past year. Something is going to have to give and I don’t know what that might be.

  • Working from home is comfortable for sure. And the lack of schedule means that people are unknowingly putting in hours beyond what they normally would at the office. At least in the office you can walk away from your desk at the end of the day.
  • Unlimited PTO and flexible work schedules sound great in theory. Except not tracking your PTO hours also means you don’t accrue them. You don’t get paid for time you don’t take off. And a flexible work schedule sounds great in theory but reality says that you’re not likely to get much support if you suddenly decide you want to work noon to 10pm Hawaiian time. Flexible really means “work longer than normal”.

Putting the FUN Back in Productivity

It’s not a secret that it’s hard to get stuff done. Procrastination is practically a super power for me. I’ve tried so many methods and systems to keep myself on track over the years that I should probably start a review site. Sadly, the battle of my executive function being on constant vacation and the inability to get organized saps a lot of my ability to execute. It’s gotten to the point where I’ve finally realized that I need to start tricking my brain into getting things done.

Any reputable researcher will tell you that dealing with neurodivergent behaviors like ADHD is all about understanding the reasons why you do the things you do. I know what needs to be done. I just don’t want to do it. Worse yet, anything that I can do to avoid working on something is going to capture my attention because I’d rather be doing something unproductive as opposed to something I don’t like. This can manifest itself in strange ways like preferring to do the dishes instead of writing a blog post or mowing the yard instead of practicing a presentation.

Not DisFUNctional

It’s taken me a while but I’ve finally come up Continue reading

Don’t OutSMART Your Goals

290C1DEE-0D66-432D-839A-C3C4B79B5F6D

I read a piece on LifeHacker yesterday that made me shake my head a bit. I’m sure the title SMART Goals Are Overrated was designed to get people to click on it, so from that perspective it succeeded. Wading into the discourse there was an outline of how SMART goals were originally designed for managers to give tasks to employees and how SMART doesn’t fit every goal you might want to set, especially personal aspirational ones. Since I have a lot of experience with using SMART goals both for myself and for others I wanted to give some perspective on why SMART may not be the best way to go for everything but you’re a fool if you don’t at least use it as a measuring tool.

SMRT, Eh?

As a recap, SMART is an acronym for the five key things you need to apply to your goal:

  • S – Specific (what are you going to do)
  • M – Measurable (how will you know when you’ve succeeded)
  • A – Attainable or Assignable (can you or the person you’ve selected do this thing)
  • R – Relevant or Relatable (is this goal appropriate for me or for the person doing it)
  • T Continue reading

A Decade of CCIE Certification

I was notified this week that I’m eligible for the 10-year CCIE plaque. Which means that it’s been a decade since I walked out of Cisco’s Building C in San Jose with a new number and a different outlook on my networking career. The cliche is that “so many things have changed” since that day and it’s absolutely accurate because the only constant in life is change.

Labbing On the Road

I think the first thing that makes me think about the passage of time since my certification is the fact that the lab where I took the exam no longer exists. Building C was sold to the company that owns and operates the San Francisco 49ers stadium just down Tasman drive from the old letter buildings. Those real estate locations were much more valuable to the NFL than to Cisco. I can’t even really go and visit my old stomping grounds any more because the buildings were gutted, renovated, and offered to other operations that aren’t from Cisco.

Now, you don’t even go to San Jose or RTP for the lab. Three years ago the labs in the US moved to Richardson, TX. The central aspect of the location Continue reading

Charting the Course For Aruba

By now you’ve seen the news that longtime CEO of Aruba Keerti Melkote is retiring. He’s decided that his 20-year journey has come to a conclusion and he is stepping down into an advisory role until the end of the HPE fiscal year on October 31, 2021. Leaving along with him are CTO Partha Narasimhan and Chief Architect Pradeep Iyer. It’s a big shift in the way that things will be done going forward for Aruba. There are already plenty of hot takes out there about how this is going to be good or bad for Aruba and for HPE depending on which source you want to read. Because I just couldn’t resist I’m going to take a stab at it too.

Happy Trails To You

Keerti is a great person. He’s smart and capable and has always surrounded himself with good people as well. The HPE acquisition honestly couldn’t have gone any better for him and his team. The term “reverse acquisition” gets used a lot and I think this is one of the few positive examples of it. Aruba became the networking division of HPE. They rebuilt the husk that was HP’s campus networking division and expanded it Continue reading

Document The First Time, Every Time

2053fountain_pen

Imagine you’re deep into a massive issue. You’ve been troubleshooting for hours trying to figure out why something isn’t working. You’ve pulled in resources to help and you’re on the line with the TAC to try and get a resolution. You know this has to be related to something recent because you just got notified about it yesterday. You’re working through logs and configuration setting trying to gain insights into what went wrong. That’s when the TAC engineer hits you with with an armor-piecing question:

When did this start happening?

Now you’re sunk. When did you first start seeing it? Was it happening before and no one noticed? Did a tree fall in the forest and no one was around to hear the sound? What is the meaning of life now?

It’s not too hard to imagine the above scenario because we’ve found ourselves in it more times than we can count. We’ve started working on a problem and traced it back to a root cause only to find out that the actual inciting incident goes back even further than that. Maybe the symptoms just took a while to show up. Perhaps someone unknowingly “fixed” the issue with a Continue reading

When Hardware Drives Software Upgrades

8006701A-85B8-4391-BD36-487B35755676

What’s your favorite version of Microsoft Windows? Is it Windows 10? Maybe it’s Windows XP? Windows 95? Odds are good that you have one version you appreciated more than most. Windows XP, Windows 7, and Windows 10 tend to rank high on the list. Windows ME and Windows 8 seem to rank pretty low. Yet, for all their impressive love and all the users clinging to them we don’t really use anything other than Windows 10 any more.

You might be tempted to say that the OS isn’t supported any longer so there’s no reason to run it. Yet we still drive vehicles that are no longer under warranty. We still buy classic cars that are older than we are and put parts in them to keep them running. Why is software different? What drives us to keep needing to upgrade our programs?

You might be shocked to learn that the most popular reason to upgrade software is, in fact, driven by hardware. It’s not the memory requirements or the fancy new user interface that drives people to move to the new platform. More often than not it’s because a new piece of hardware has requirements that only work on Continue reading

Networking Isn’t Just A Tool

BlueFiberOptic

It’s another event week for me at Networking Field Day 25 and I’m continually impressed with the level of technology that we see in the networking world. I think back to how things looked when I was still deploying the networks I built and it seems like a hundred years ago instead of a decade. More software driving better outcomes for users. Easier collection of analytics and telemetry to understand how to tune things and make them faster and better. And, honestly, more need for advanced technical people to tune everything and make it work better.

When you consider that the last year has been done over the Internet for most of us it gets even crazier. Meetings, software productivity, and even food delivery has been driven by apps running in the cloud that we communicate with over the Internet. I can remember a time when I didn’t have a mobile phone in my pocket with Internet capabilities. Today I can barely imagine not having it at my fingertips. When the network is not doing things the way we want we quickly find out how dependent we’ve become on our connectivity.

Generational Differences

My children are amazed that dial-up networking Continue reading

Knowledge is Powerful and Needs to Be Shared

WritingPen

A tweet this morning from my friend Stephanie stood out in my timeline because she’s talking about something I’ve seen happen over and over again in my lifetime:

How many times have we seen this in our organizations? People want to hoard knowledge because they feel like it’s power. Maybe they’re worried that if anyone knew what they know it would mean they could get fired. Perhaps they enjoy holding the keys to the kingdom and not allowing anyone else to do something or know something they know. It could even be that they like the idea of mystery in the air and not allowing people to know the whole truth keeps things alive, as the founders of Coca-Cola and Colonel Sanders will happily tell you.

Over the years I’ve figured out that hoarding knowledge leads to ruin. I’ve been involved in so many scenarios were a lack of knowledge sharing ended up Continue reading

Fast Friday Thoughts from the Woods

I’m at camp this week helping put on the second weekend of the Last Frontier Council Wood Badge course which is my idea of a vacation. I’m learning a lot, teaching a lot more, and having fun. But that does’t mean I’m not working too. Lots of fun conversations that make me recall the way people consume information, communicate what they know, and all too often overlook the important things they take for granted.

  • Why is IT one of the few disciplines that expects people to come in fully trained and do the job instead of learning while doing it? Is that because hiring managers don’t want to train people? Or is it because senior people are less likely to impart knowledge to protect their jobs? I don’t have a good answer but I know what the result looks like and it’s not something that’s positive, either for the people doing the job or how it’s perceived outside of IT.
  • There is a ton of value in doing something for real instead of just planning it and calling it good. DR plans need to be tested. Network changes need to be mocked up. No matter what kind of critical thing Continue reading

Racing On the Edge of Burnout

Exhibit A:

It’s been a year and more and I think a lot of us are on the ragged edge of burning out completely. Those that think they are superhuman and can just keep grinding away at things without acknowledging what’s going on are kidding themselves. I know I’m feeling it too even though I have a pretty decent handle on what’s going on. Let’s explore some of the ways it’s impacting us and what should be done, if anything can even be done.

Creativity Black Hole

I don’t feel like doing anything remotely creative right now. The cooking will get finished. The dishes will be done. The things in my floor will be picked up and put away. But beyond that? Good. Luck. I’m not feeling any kind of drive to do anything beyond that.

Remember when everyone was picking up quarantine skills? Baking, cooking, knitting, crocheting, home improvement, or even an instrument? Those were fun days filled with massive uncertainty and a need to distract ourselves from what might be coming next. However, those skill pickups are things that need Continue reading

Real Life Ensues

Hey everyone! You probably noticed that I didn’t post a blog last week. Which means for the first time in over ten years I didn’t post one. The streak is done. Why? Well, real life decided to take over for a bit. I was up to my eyeballs in helping put on our BSA council Wood Badge course. I had a great time and completely lost track of time while I was there. And that means I didn’t get a chance to post something. Which is a perfect excuse to discuss why I set goals the way that I do.

Consistency Is Key

I write a lot. Between my blog here and the writing I do for Gestalt IT I do at least 2-3 posts a week. That’s on top of any briefing notes I type out or tweets I send when I have the energy to try and be funny. For someone that felt they weren’t a prolific writer in the past I can honestly say I spend a lot of time writing out things now. Which means that I have to try and keep a consistent schedule of doing things or else I will get swamped by some other Continue reading

Tom’s Corner and Turning Another Corner

Thanks to everyone that popped in for Tom’s Virtual Corner at Cisco Live Global 2021. It was a great time filled with chats about nothing in particular, crazy stories about unimportant things, and even the occasional funny picture. It was just was Tom’s Corner has always been. A way for the community to come together and be around each other in a relaxing and low-key environment. Maybe we couldn’t meet in person but we got together when we needed it the most.

There was also something else that Tom’s Corner has represented for me for the last year that I didn’t even catch until it was pointed out to me by my wonderful wife Kristin (@MrsNetwrkingNerd). Tom’s Corner was the start of something that made me feel better about everything.

Get On Up and Move

After Tom’s Virtual Corner in 2020, I was energized. I needed to get up and get things done after sitting in a chair for hours talking to all my absent friends and getting the energy I needed to feel after months of being locked away during a pandemic. I felt on top of the world for the first time in quite a while. Continue reading

Servant Leadership and Standing Out

LonePawn

My son is fifteen and he’s the typical teenager that either thinks he’s being asked to do way too much or he’s not getting recognized for what he’s accomplished. That last part is hard for him because he’s a bit humble and doesn’t like to tout his own work. I once told him that he didn’t need to do that because he stands out to the people that matter. He did the typical teenager thing where he fought me and said that no one noticed anything he did. I told him that if you do things the way they’re supposed to be done and don’t spend your whole day crowing about what you’re doing that the right people will most assuredly notice.

The worry that your work is going unnoticed isn’t unfounded among teenagers or adults. How many times have we asked ourselves in our daily work roles if we matter? It takes about two weeks worth of meetings in a typical IT department for you to see how things go. There are those that coast by with the knowledge they obtained years ago that have their niche and they intend to fill it. Their entire purpose is to avoid Continue reading

Basics First and Basics Last

This week I found my tech life colliding with my normal life in an unintended and somewhat enlightening way. I went to a store to pick up something that was out of stock and while I was there making small talk the person behind the counter asked me what I did for a living. I mentioned technology and he said that he was going to college for a degree in MIS, which just happens to be the thing I have my degree in. We chatted about that for a few more minutes before he asked me something I get asked all the time.

“What is the one thing I need to make sure I pay attention to in my courses?”

It’s simple enough, right? You’ve done this before and you have the benefit of hindsight. What is the one thing that is most important to know and not screw up? The possible answers floating through my head were all about programming or analytical methods or even the dreaded infrastructure class I slept through and then made a career out of. But what I said was the most boring and most critical answer one could give.

“You need to know Continue reading
