Given how crazy everything is right now, it’s important to try and stay sane. And that’s harder than it sounds to be honest. Our mental health is being degraded by the day. Work stress, personal stress, and family stress are all contributing to a huge amount of problems for all of us. I can freely admit that I’m there myself. My mental state has been challenged as of late with a lot of things and I’m hoping that I’m going to pull myself out of this funk soon with the help of my wife @MrsNetwrkngnerd and some other things to make me happier.
One of the things that I wanted to share with you all today was one of the things I’ve been trying to be mindful about over the course of the last few months. It’s about appreciation. We show appreciation all the time for people. It’s nothing new, really. But I want you to think about the last time you said “thank you” to someone. Was it a simple exchange for a service? Was it just a reflex to some action? Kind of like saying “you’re welcome” afterwards? I’d be willing to bet that most of the people Continue reading
I’ve been in the middle of Mobility Field Day 5 this week with a great group of friends and presenters. There’s a lot to unpack. I wanted to share some quick thoughts around wireless technologies and where we’re headed with it.
Have you noticed that every meeting needs to be on video now? Of course, that’s a rhetorical question. It’s one of the first and most constant things that is brought up in the pandemic-influenced tech community of today. Meetings that used to be telephone-only or even wordy emails are now video chats that take half an hour or more. People complain that they are spending time and money to spruce up their office to look presentable at 720p to people that likely aren’t paying attention anyway. It’s a common complaint. But have you ever thought about why?
There are three major styles of learning that get brought up in academic courses.
You no doubt saw the news this week that HPE announced that they’re buying Silver Peak for just shy of $1 billion dollars. It’s a good exit for Silver Peak and should provide some great benefits for both companies. There was a bit of interesting discussion around where this fits in the bigger picture for HPE, Aruba, and the cloud. I figured I’d throw my hat in the ring and take a turn discussing it.
First and foremost, let’s discuss where this acquisition is headed. HPE announced it and they’re the ones holding the purse strings. But the acquisition post was courtesy of Keerti Melkote, who runs the Aruba, a Hewlett Packard Enterprise Company (Aruba) side of the house. Why is that? It’s because HPE “reverse acquired” Aruba and sent all their networking expertise and hardware down to the Arubans to get things done.
I would venture to say that Aruba’s acquisition was the best decision HPE could have made. It gave them immediate expertise in an area they sorely needed help. It gave Aruba a platform to build on and innovate from. And it ultimately allowed HPE to shore up their campus networking story while trying Continue reading
It’s Friday and we’re technically halfway into the year now. Which means things should be going smoother soon, right? Here’s hoping, at least.
Since I seem to have a lot more time on my hands without travel thanks to current…things, I’ve been consuming podcasts more and more during my morning workouts. I’ve got a decent list going now and I wanted to share it with you. Here are my favorite podcasts (not including the one that I do for Gestalt IT, the On-Premise IT Roundtable:
You’ve probably been hearing a lot about analytics and artificial intelligence in the past couple of years. Every software platform under the sun is looking to increase their visibility into the way that networks and systems behave. They can then take that data and plug it into a model and make recommendations about the way things need to be configured or designed.
Using analytics to aid troubleshooting is nothing new. We used to be able to tell when hard disks were about to go bad because of SMART reporting. Today we can use predictive analysis to determine when the disk has passed the point of no return and should be replaced well ahead of the actual failure. We can even plug that data into an AI algorithm to determine which drives on which devices need to be examined first based on a chart of performance data.
The power of this kind of data-driven network and systems operation does help our beleaguered IT departments feel as though they have a handle on things. And the power that data can offer to us has it being tracked like a precious natural resource. More than a few times I’ve heard data referred to Continue reading
Okay, the world is indeed crazy. We can’t hide from it or hope that it just blows over sooner or later. We’re dealing with it now and that means it’s impacting our work, our family lives, and even our sanity from time to time. One of the stalwart things that has been impacted by this is the summer conference schedule. We’ve had Aruba Atmosphere, Cisco Live, VMworld, and even Microsoft Ignite transition from being held in-person to a virtual format complete with shortened schedules and pre-recorded sessions. I’ve attended a couple of these so far for work and as an analyst, and I think I’ve figured it out.
If you come to a conference for content and sessions, you’ll love virtual events. If you come for any other reason, virtual isn’t going to work for you.
Let’s break this down because there’s a lot to unpack.
Conferences are first and foremost about disseminating information. Want to learn what new solutions and technologies have been launched? It’s probably going to be announced either right before or during the conference. Want to learn the ins-and-outs of this specific protocol? There’s probably a session on it or a chance to ask Continue reading
One of the things I picked up during the quarantine is a new-found interest in cooking. I’ve been spending more time researching recipes and trying to understand how my previous efforts to be a four-star chef have fallen flat. Thankfully, practice does indeed make perfect. I’m slowly getting better , which is to say that my family will actually eat my cooking now instead of just deciding that pizza for the fourth night in a row is a good choice.
One of the things I learned as I went on was about salt. Sodium Chloride is a magical substance. Someone once told me that if you taste a dish and you know it needs something but you’re not quite sure what that something is, the answer is probably salt. It does a lot to tie flavors together. But it’s also a fickle substance. It has the power to make or break a dish in very small amounts. It can be the difference between perfection and disaster. As it turns out, it’s a lot like security too.
Security and salt are alike in the first way because you need the right amount to make things work. Continue reading
How much did your last laptop cost? You probably know down to the penny. How much time did it take for you to put together your last Powerpoint deck or fix an issue for a customer? You can probably track that time in the hours you recorded on your timesheet. What about the last big meeting you had of the department? Can you figure out how many hours combined of time that it took to get the business discussed? Pretty easy to calculate when you know how many people and how long it took.
All of these examples are ways that we track resources in the workplace. We want to know how many dollars were invested in a particular tool. We want to figure out how many hours someone has worked on a project or a proposal. We want to know how much of the company’s resources are being invested so we can track it and understand productivity and such. But when’s the last time you tracked your personal resources? I’m not talking about work you do or money you spend. I’m talking about something more personal than that. Because one of the things that I’ve seen recently that is Continue reading
If I asked you to summarize the great works of literature in a few paragraphs, how would you do it? Would you read over the whole thing and try to give a play-by-play of the book? Would it be more like Cliff’s Notes, summarizing the major themes but skipping over the details? Maybe you’d offer up the conclusion only and leave it as an exercise to the reader to find out? There are a lot of ways to do it and almost all of them seem insurmountable.
What if there was an easy way to jump right into starting to discuss a topic or summarize something? What if you could find a way to easily get people interested in your ideas? Believe or not, it’s not as hard as you might think. People usually freak out because they feel like there are too many places to start when they want to write something. They decide to try and figure out the perfect way to get going and, more often than not, they paralyze themselves with inaction.
So how do you get things moving? You have to find the hook.
What’s the hook? Most people think it’s Continue reading
One of the things that I look forward to most during Cisco Live is the opportunity to meet with people. It’s been quite a few years since I’ve been to a session during the conference. My work with Tech Field Day has kept me very busy for the past several Cisco Live events. But at the end of the day I enjoy strolling down to the Social Media hub and talking to anyone I see. Because people make Cisco Live what it is.
The Legend of Tom’s Corner has grown over the years. It’s more than just a few tables in a place where people hang out. It stands for a community. It means a lot to so many different people. It’s about meeting new friends and catching up with old ones and feeling like you belong. For so many, Tom’s Corner and the Social Media Hub is the center of Cisco Live.
And yet, we now live in extraordinary times. The plan we had for what Cisco Live would look like for us earlier this year is radically different right now. Prohibitions on travel and meetings in large groups means we will be experiencing Cisco Live from our homes Continue reading
I’m a storyteller. I realize this based on the fact that I tell them a lot. I’ve been told by a lot of people that I tell stories all the time. I’m okay with this. And a lot of the time I’m totally good at it. But one of the side effects of being someone that enjoys telling stories is that you recognize them in others and you start critiquing.
One of the more recent trends I’ve seen in product marketing revolves around stories. We’ve seen people telling all kinds of narratives about how disparate pieces of the puzzle fit together. It’s important because it frames the discussion for everyone. But I’ve also noticed some companies focus less on the framing story and more on the pieces. And it made me realize that’s a different kind of story.
Merriam-Webster defines an anthology as a collection of selected literary pieces or passages or works of art or music. When I think of an anthology movie or video series, I think of a collection of disconnected stories around a framing device. Sometimes that device is as tenuous as a shared narrator, such as the Twilight Zone or Tales from Continue reading
Sometimes I have to play the role of the genial host and I don’t get to express my true opinion on things. After all, a good podcast host is really just there to keep the peace and ensure the guests get to say their words, right?
I once said that every random feature in a certain network operating system somehow came from a million-dollar PO that needed to be closed. It reflects my personal opinion that sometimes the things we see in code don’t always reflect reality. But how do you decide what to build if you’re not listening to customers?
It’s a tough gamble to take. You can guess at what people are going to want to include and hope that you get it right. Other times you’re going to goof and put something your code that no one uses. It’s a delicate balance. One of the biggest traps that a company can fall into is waiting for their Continue reading
“Failure is a harsh teacher because it gives the test first and the lesson afterward.” — Vernon Law
I’m seeing a thread going around on Twitter today that is encouraging people to share their stories of failure in their career. Maybe it was a time they created a security hole in a huge application. Perhaps it was creating a routing loop in a global corporation. Or maybe it was something as simple as getting confused about two mailboxes and deleting the wrong one and realizing your mail platform doesn’t have undelete functionality.
We fail all the time. We try our hardest and whatever happens isn’t what we want. Some of those that fail just give up and assume that juggling isn’t for them or that they can never do a handstand. Others keep persevering through the pain and challenge and eventually succeed because they learn what they need to know in order to complete their tasks. Failure is common.
What is different is how we process the learning. Some people repeat the same mistakes over and over again because they never learn from them. In a professional setting, toggling the wrong switch when you create someone’s new account has Continue reading
I have a Disney+ account. I have kids and I like Star Wars, so it made sense. I got it all set up the day it came out and started binge watching the Mandalorian. However, in my haste to get things up and running I reused an old password instead of practicing good hygiene. As the titular character might scold me, “This is not the way.” I didn’t think anything about it until I got a notification that someone from New Jersey logged into my account.
I panicked and reset my password like a good security person should have done in the first place. I waited for the usual complaints that people had been logged out of the app and prepared to log everyone in again and figure out how to remove my New Jersey interloper. Imagine my surprise when no one came to ask me to turn Phineas and Ferb back on. Imagine my further surprise when I looked in the app and on the Disney+ website and couldn’t find a way to see which devices were logged in to this account. Nor could I find a way to disconnect a rogue device as I could with Netflix Continue reading
It’s funny how little things change in the middle of big, world changing experiences. I’ve noticed that my daily blog viewership has gone down, as have many other folks I’ve talked to. The number of people reading has been reduced for some reason. However the number of video views of content on other platforms like Youtube has gone up dramatically. It’s almost like the people that were reading because they wanted to get a quick digest now have the free time to watch a whole video on a topic.
I got on the bandwagon too, recently publishing my first episode of Tomversations this week. I’ve also talked to several friends that are either starting or restarting a podcast. The gold mine for content creation has opened for business. However, I still hear the same refrains about content that I’ve heard for years when I talk about writing:
These are all valid questions, no matter what medium you’re developing for. But let me give you a roadmap to take those objections, turn them on their heads, and be Continue reading
If you configure a newsreader to alert you every time someone hijacks a BGP autonomous system (AS), it will probably go off at least once a week. The most recent one was on the first of April courtesy of Rostelecom. But they’re not the only one. They’re just the latest. The incidences of people redirecting BGP, either by accident or be design, are becoming more and more frequent. And as we rely more and more on things like cloud computing and online applications to do our daily work and live our lives, the impact of these hijacks is becoming more and more critical.
BGP isn’t the oldest thing on the Internet. RFC 1105 is the initial draft of Border Gateway Protocol. The version that we use today, BGP4, is documented in RFC 4271. It’s a protocol that has enjoyed a long history of revisions and a reviled history of making networking engineers’ lives difficult. But why is that? How can a routing protocol be so critical and yet obtuse?
My friend Marko Milivojevic famously stated in his CCIE training career that, “BGP isn’t a routing protocol. It’s a policy engine.” When you look at the decisions of Continue reading
Back during Networking Field Day 22, I was having a fun conversation with Phil Gervasi (@Network_Phil) and Carl Fugate (@CarlFugate) about SD-WAN and innovation. I mentioned that it was fascinating to see how SD-WAN companies kept innovating but that bigger, more established companies that had bought into SD-WAN seemed to be having issues catching up. As our conversation continued I realized that technical debt plays a huge role in startup culture in all factors, not just with SD-WAN. But we’ll use SD-WAN as an example here to focus our discussion.
Big companies have investments in supply chains. They have products that are designed in a certain way because it’s the least expensive way to develop the project or it involves using technology developed by the company that gives them a competitive advantage. Think about something like the Cisco Nexus 9000-series switches that launched with Cisco ACI. Every one of them came with the Insieme ASIC that was built to accelerate the policy component of ACI. Whether or not you wanted to use ACI or Insieme in your deployment, you were getting the ASIC in the switch.
Policies like this Continue reading
I’m a huge fan of video games. I love playing them, especially on my old consoles from my formative years. The original Nintendo consoles were my childhood friends as much as anything else. By the time I graduated from high school, everyone had started moving toward the Sony Playstation. I didn’t end up buying into that ecosystem as I started college. Instead, I just waited for my brother to pick up a new console and give me his old one.
This meant I was always behind the curve on getting to play the latest games. I was fine with that, since the games I wanted to play were on the old console. The new one didn’t have anything that interested me. And by the time the games that I wanted to play did come out it wouldn’t be long until my brother got a new one anyway. But one thing I kept hearing was that the Playstation was backwards compatible with the old generation of games. I could buy a current console and play most of the older games on it. I wondered how they managed to pull that off since Nintendo never did.
When I was older, I did Continue reading
