I had a great time recording a fun episode of Seeking Truth in Networking, an awesome podcast with my friends Derick Winkworth and Brandon Heller. We talked a lot about a variety of different topics, but the one I want to spend a few more minutes on here came in the first five minutes. Brandon asked me what question I liked to be asked and I mentioned that love to be asked about learning. My explanation included the following line:
I feel like the gap between people that don’t understand something and the willfully ignorant is that ability to take a step out and say “I don’t know the answer to this but I’m going to find out.”
I’ve always said that true learners are the ones that don’t accept the unknown. They want to find the answer. They want to be able to understand something as completely as they can. Those that I consider to be willfully ignorant choose not to do that.
Note that there is a difference between incidentally ignorant and willfully ignorant. People who are incidentally ignorant are unaware they don’t know something. They haven’t had the opportunity to learn or change their thought Continue reading
It’s almost December and the signs are pointing to a continuation of the current state of working from home for a lot of people out there. Whether it’s a surge in cases that is causing businesses to close again or a change in the way your company looks at offices and remote work, you’re likely going to ring in the new year at your home keyboard in your pajamas with a cup of something steaming next to your desk.
We have all spent a lot of time and money investing in better conditions for ourselves at home. Perhaps it was a fancy new mesh chair or a more ergonomic keyboard. It could have been a bigger monitor with a resolution increase or a better webcam for the dozen or so Zoom meetings that have replaced the water cooler. There may even be more equipment in store, such as a better home wireless setup or even a corporate SD-WAN solution to help with network latency. However, have you considered what might happen if it all goes wrong and you need to be online?
Outages happen more often than we realize. That’s never been more evident than the situation Continue reading
First things first: Go watch this great video on lock-in from Ethan Banks (@ECBanks). We’ll reference it.
Welcome back. Still carrying that pitchfork around screaming about how you want to avoid vendor lock-in? Ready to build the most perfect automation system in history that does multi-cloud, multi-vendor, multi-protocol networking in a seamless manner with full documentation? Nice. How hard was is to build that unicorn farm?
I get it. No one wants to be beholden to a specific vendor. No one likes being forced into buying things. Everyone hates the life of the engineer forced to work on something they don’t like or had to use because someone needed a new boat. Or do they?
What kind of car do you drive? Odds are good you’re either ready to get a new one or you’re proud of what you’re driving. I find that the more flashy a car is the more likely people are to talk about how amazing it is. And when there are two dominant manufacturers in a market for cars, you tend to see people dividing into camps to sing the praises of their favorite brands. Ford people love their Continue reading
With the insanity of the pandemic and the knowledge drain that we’re seeing across IT in general, there’s never been a more important time than right now to help out those that are getting started on this rise. The calls for mentors across the community is heartwarming. I’ve been excited personally to see many recognizable names and faces in the Security, Networking, and Wireless communities reaching out to let people know they are available to mentor others or connect them with potential mentors. It’s a way to give back and provide servant leadership to those that need it.
If you’re someone that’s reading this blog right now and looking for a mentor you’re in luck. There are dozens of people out there that are willing to help you out. The kindness of the community is without bounds and there are those that know what it was like to wander through the wilderness for a while before getting on the right track. They are the ones that will be of the most help to you. However, before you slide into someone’s DMs looking for help, you need to keep a few things in mind.
The single Continue reading
Wanna make your security team’s blood run cold? Remind them that all that time and effort they put in to securing the enterprise from attackers and data exfiltration is currently sitting unused while we all work from home. You might have even heard them screaming at the sky just now.
Enterprise security isn’t easy, nor should it be. We constantly have to be on the offensive to find new attack vectors and hunt down threats and exploits. We have spent years and careers building defense-in-depth to an artform not unlike making buttery croissants. It’s all great when that apparatus is protecting our enterprise data center and cloud presence like a Scottish castle repelling invaders. Right now we’re in the wilderness with nothing but a tired sentry to protect us from the marauders.
During Security Field Day 4, I led a discussion panel with the delegates about the challenges of working from home securely. Here’s a link to our discussion that I wanted to spend some time elaborating on:
BYOD was a huge watershed moment for the enterprise because we realized for the first time that we had to learn to secure other people’s Continue reading
Can you hear me? Are you listening to me? Those two statements are used frequently to see if someone is paying attention to what you’re saying. Their connotation is very different though. One asks a question about whether you can tell if there are words coming out of someone’s mouth. Is the language something you can process? The other question is all about understanding.
“Seek first to understand,then to be understood.” – Stephen Covey
Listening is hard. Like super hard. How often do you find yourself on a conference call with your mind wandering to other things you need to take care of? How many times have we seen someone shopping online for shoes or camping gear instead of taking notes on the call they should be paying attention to? They answer is more often than we should.
Attention spans are hard for everyone, whether you’re affected by attention disorders or have normal brain chemistry. Our minds hate being bored. They’re always looking for a way to escape to something more exciting and stimulating. You know you can feel it when there’s a topic that seriously interests you and pulls you in versus the same old Continue reading
When I was an intern at IBM twenty something years ago, my job was deploying new laptops to people. The job was easy enough. Transfer their few hundred megabytes of data to the new machine and ensure their email was all setup correctly. There was a checklist that needed to be followed in order to ensure that it was done correctly.
When I arrived for my internship, one of my friends was there finishing his. He was supposed to train me in how to do the job before he went back to school. He helped me through the first day of deploying laptops following the procedure. The next day he handed me a different sheet with some of the same information but in a different order. He said, “I realized we had too many reboots in the process and this way cuts about twenty minutes off the deployment time.” I’m all about saving time so I jumped at the chance.
Everything went smashingly for the next month or so. My friend was back at school and I used his modified procedure to be as productive as possible. One day, my mentor wanted to shadow my deployment day to see Continue reading
Have you been playing Among Us? If you haven’t, your kids definitely have. I found out about it a few weeks ago because my children suddenly became Batman-level detectives and knew how to ask the kinds of interview questions that would make the FBI proud. In short, the game is all about finding the imposters in your midst based on their behavior and voting them out of the group to win. Sometimes you get it right. Other times you get it wrong and vote out someone who was doing legitimate tasks. It’s all a matter of perception.
Now, let’s look at another situation where we see this kind of behavior in a different light. You probably guessed where this is going already. We’re going to talk about Imposter Syndrome in our non-gaming lives and how it affects us. We may even make reference to pop culture along the way.
I was thinking about this because something I said a few years ago at Security Field Day 1 popped back up in my feed. I was giving a speech at the beginning of the first day to the delegates and I wanted them to know that Continue reading
The pandemic has really done a number on most of our office environments. For some, we went from being in a corporate enterprise with desks and coffee makers to being at home with a slightly different desk and perhaps a slightly better coffee maker. However, one thing that didn’t improve was our home network.
For the most part, the home network has been operating on a scale radically different from those of the average corporate environment. Taking away the discrepancies in Internet speed for a moment you would have a hard time arguing that most home wireless gear is as good or better than the equivalent enterprise solution. Most of us end up buying our equipment from the local big box store and are likely shopping as much on price as we are on features. As long as it supports our phones, gaming consoles, and the streaming box we picked up we’re happy. We don’t need QoS or rogue detection.
However, we now live in a world where the enterprise is our home. We live at work as much as we work where we live. Extended hours means we typically work past 5:00 pm or start earlier than 8:00 or Continue reading
I know I’m a little late getting this post out but Networking Field Day 23 was a jam-packed event with lots of things to digest. I wanted to share some quick thoughts about it here that should create some discussion amongst the community, hopefully.
Today is a milestone for me. Ten years ago I picked up a virtual notepad for the first time and committed my first blog post to the ether. It’s been a wild ride ever since. It also marks the milestone of being the job that I’ve held the longest so far in my career.
Blogging has been a huge boon for me. I’ve become a better writer in the last decade. I’ve learned how to ask the right questions and get good material for a story instead of just putting out what someone wants me to say. I’ve learned that being a pseudo-journalist is a thing you can do and have fun with.
I’ve written a ton over the years. 751 posts, as a matter of fact (counting this one). I’ve always tried to hold myself to a standard of getting something out once a week. Aside from the few times when I’ve tried to push that to twice a week I’ve held up pretty well. Yeah, I’ve slipped and the day job has gotten in the way more than once. However, keeping myself to a strict schedule has ensured that my attention stays focused on this blog and that Continue reading
One thing I’ve found out over the past decade of writing is that some problems are easy enough to solve that we sometimes forget about them. Maybe it’s something you encounter once in a great while. Perhaps it’s something that needed a little extra thought or a novel reconfiguration of an existing solution. Something so minor that you didn’t even think to write it down. Until you run into the problem again.
The truth behind most of these simple problems is that the solutions aren’t always apparent. Sure, you might be a genius when it comes to fixing the network or the storage array. Maybe you figured out how to install some new software to do a thing in a way that wasn’t intended. But did you write any of it down for later use? Did you make sure to record what you’ve done so someone else can use it for reference?
Part of the reason why I started blogging was to have those written solutions to problems I couldn’t find a quick answer to. What it became was way more than I had originally intended. But the posts that I write that still get the most attention aren’t my Continue reading
This morning I was going to go for a run and I needed to find a rain jacket to keep from getting completely soaked. I knew I had one in my hiking backpack but couldn’t locate it. I searched for at least ten minutes in every spot I could think of and couldn’t find it. That is, until I looked under the brain of the pack and found it right next to the pack’s rain cover. Then I remembered that my past self had put the jacket there for safe keeping because I knew that if I ever needed to use the pack rain cover I would likely need to have my rain jacket as well. Present me wasn’t as happy to find out past me was so accommodating.
I realized after this little situation that I’ve grown accustomed to keeping my bags organized in a certain way both for ease of use and ease of inspection. Whether it’s a hiking backpack or an IT sling bag full of gadgets I’ve always tried to set things up in simple, sane manner to figure out how to find the tools I need quickly and also discover if any of them are Continue reading
It’s a long weekend in the US thanks to Labor Day. Which is basically signaling the end of the summer months. Or maybe the end of March depending on how you look at it. The rest of the year is packed full of more virtual Zoom calls, conferences, Tech Field Day events, and all the fun you can have looking at virtual leaves turning colors.
It’s been an interesting news week for some things. And if you take out all the speculation about who is going to end up watching TikTok you are left with not much else. So I’ve been wondering out loud about a few things that I thought I would share.
My friend Joshua Williams (@802DotMe) texted me today with a great quote that I wanted to share with you that made me think about certifications:
You’ve probably already thought through this extensively, and maybe even written about it, but after sitting through another 8 hour practical exam yesterday I’m more convinced than ever that expert level exams from technical companies are more analogous to a gimmicky Food Network TV show than real world application of technical acumen. They don’t care so much about my skill level as they do about what kind of meal I can prepare in 30 minutes using Tialapia, grapes, and Dr. Pepper syrup with my salt shaker taken away halfway through.
I laughed because it’s true. And then I thought about it more and realized he’s way more than right. We know for a fact that companies love to increase the level of challenge in their exams from novice to expert. It’s a way to weed out the people that aren’t committed to learning about something. However, as the questions and tasks get harder it becomes much more difficult to get a good sense of how candidates are going to perform.
If you had told me last year at this time that remote management of devices would be a huge thing in 2020 I might have agreed but laughed quietly. We were traveling down the path of simultaneously removing hardware from our organizations and deploying IoT devices that could be managed easily from the cloud. We didn’t need to access stuff like we did in the past. Even if we did, it was easy to just SSH or console into the system from a jump box inside the corporate firewall. After all, who wants to work on something when you’re not in the office?
Um, yeah. Surprise, surprise.
Turns out 2020 is the Year of Having Our Hair Lit On Fire. Which is a catchy song someone should record. But it’s also the year where we have learned how to stand up 100% Work From Home VPN setups within a week, deploy architecture to the cloud and refactor on the fly to help employees stay productive, and institute massive change freezes in the corporate data center because no one can drive in to do a reboot if someone forgets to do commit confirmed or reload in 5.
Remote Continue reading
During a recent episode of the Packet Pushers Podcast, Greg and Drew talked about the fact that bandwidth just keeps increasing and we live in a world where the solution to most problems is to just increase the pipeline to the data center or to the Internet. I came into networking after the heady days of ISDN lines everywhere and trying to do traffic shaping on slow frame relay links. But I also believe that we’re going to quickly find ourselves in a pickle when it comes to bandwidth.
My grandparents were alive during the Great Depression. They remember what it was like to have to struggle to find food or make ends meet. That one singular experience transformed the way they lived their lives. If you have a relative or know of someone that lived through that time, you probably have noticed they have some interesting habits. They may keep lots of cash on hand stored in various places around the house. They may do things like peel labels from jelly jars and use them as cups. They may even go to great lengths to preserve as much as they can for reuse later “just in Continue reading
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.
