Video And The Death Of Dialog

I was reading a trivia article the other day about the excellent movie Sex, Lies, & Videotape when a comment by the director, Stephen Soderbergh, caught my eye. The quote, from this article talks about how people use video as a way to distance ourselves from events. Soderbergh used it as a metaphor in a movie made in 1989. In today’s society, I think video is having this kind of impact on our careers and our discourse in a much bigger way.

Writing It Down In Pictures

People have become huge consumers of video. YouTube gets massive amounts of traffic. Devices have video recording capabilities built in. It’s not uncommon to see a GoPro camera attached to anything and everything and see people posting videos online of things that happen.

My son is a huge fan of videos about watching other people play video games. He’ll watch hours of video of someone playing a game and narrating the experience. When I tell him that he’s capable of playing the game himself he just tells me, “It’s not as fun that way Dad.” I, too, have noticed that a lot of things that would normally have been written down are Continue reading

Wireless As We Know It Is Dead

Congratulations! We have managed to slay the beast that is wireless. We’ve driven a stake through it’s heart and prevented it from destroying civilization. We’ve taken a nascent technology with potential and turned it into the same faceless corporate technology as the Ethernet that it replaced. Alarmist? Not hardly. Let’s take a look at how 802.11 managed to come to an inglorious end.

Maturing Or Growing Up

Wireless used to be the wild frontier of networking. Sure, those access points bridged to the traditional network and produced packets and frames like all the other equipment. But wireless was unregulated. It didn’t conform to the plans of the networking team. People could go buy a wireless access point and put it under their desk to make that shiny new laptop with 802.11b work without needing to be plugged in.

Wireless used to be about getting connectivity. It used to be about squirreling away secret gear in the hopes of getting a leg up on the poor schmuck in the next cube that had to stay chained to his six feet of network connectivity under the desk. That was before the professionals came in. They changed wireless. They put a Continue reading

Thoughts On Encryption

The debate on encryption has heated up significantly in the last couple of months. Most of the recent discussion has revolved around a particular device in a specific case but encryption is older than that. Modern encryption systems represent the culmination of centuries of development of making sure things aren’t seen.

Encryption As A Weapon

Did you know that twenty years ago the U.S. Government classified encryption as a munition? Data encryption was classified as a military asset and placed on the U.S. Munitions List as an auxiliary asset. The control of encryption as a military asset meant that exporting strong encryption to foreign countries was against the law. For a number of years the only thing that could be exported without fear of legal impact was regular old Data Encryption Standard (DES) methods. Even 3DES, which is theoretically much stronger but practically not much better than it’s older counterpart, was restricted for export to foreign countries.

While the rules around encryption export have been relaxed since the early 2000s, there are still some restrictions in place. Those rules are for countries that are on U.S. Government watch lists for terror states or governments deemed “rogue” states. Continue reading

Don’t Touch My Mustache, Aruba!

It’s been a year since Aruba Networks became Aruba, a Hewlett-Packard Enterprise Company. It’s  been an interesting ride for everyone involved so far. There’s been some integration between the HPE Networking division and the Aruba teams. There’s been presentations and messaging and lots of other fun stuff. But it all really comes down to the policy of non-interference.

Don’t Tread On Me

HPE has done an admirable job of keeping their hands off of Aruba. It sounds almost comical. How many companies have acquired a new piece and then done everything possible to integrate it into their existing core business? How many products have had their identity obliterated to fit in with the existing model number structure?

Aruba isn’t just a survivor. It’s come out of the other side of this acquisition healthy and happy and with a bigger piece of the pie. Dominick Orr didn’t just get to keep his company. Instead, he got all of HPE’s networking division in the deal! That works out very well for them. It allows Aruba to help integrate the HPE networking portfolio into their existing product lines.

Aruba had a switching portfolio before the acquisition. But that was just an afterthought. It Continue reading

Slacking Off

A Candlestick Phone (image courtesy of WIkipedia)

There’s a great piece today on how Slack is causing disruption in people’s work habits. Slack is a program that has dedicated itself to getting rid of email, yet we now find ourselves mired in Slack team after Slack team. I believe the real issue isn’t with Slack but instead with the way that our brains are wired to handle communication.

Interrupt Driven

People get interrupted all the time. It’s a fact of life if you work in business, not just IT. Even if you have your head down typing away at a keyboard and you’ve closed out all other forms of distraction, a pop up from an email or a ringing or vibrating phone will jar your concentration out of the groove and force your brain to deal with this new intruder into your solitude.

That’s evolution working against you. When we were hunters and gatherers our brain had to learn how to deal with external threats when we were focused on a task like stalking a mammoth or looking for sprouts on the forest floor. Our eyes are even developed to take advantage of this. Your peripheral vision will pick up Continue reading

Drowning in the Data of Things

If you saw the news coming out of Cisco Live Berlin, you probably noticed that Internet of Things (IoT) was in every other announcement. I wrote about the impact of the new Digital Ceiling initiative already, but I think that IoT is a bit deeper than that. The other thing that seems to go hand in hand with discussion of IoT is big data. And for most of us, that big data is going to be a big problem.

Seen And Not Heard

Internet of Things is about dumb devices getting smart. Think Flowers for Algernon. Only now, instead of them just being smarter they are also going to be very talkative too. The amount of data that these devices used to hold captive will be unleashed on something. We assume that the data is going to be sent to a central collection point or polled from the device by an API call or a program that is mining the data for another party. But do you know who isn’t going to be getting that data? Us.

IoT devices are going to be talking to providers and data collection systems and, in a lot of cases, each other. But they Continue reading

Will Cisco Shine On?

Cisco announced their new Digital Ceiling initiative today at Cisco Live Berlin. Here’s the marketing part:

And here’s the breakdown of protocols and stuff:

Funny enough, here’s a presentation from just three weeks ago at Networking Field Day 11 on a very similar subject:

Cisco is moving into Internet of Things (IoT) big time. They have at least learned that the consumer side of IoT isn’t a fun space to play in. With the growth of cloud connectivity and other things on that side of the market, Cisco knows that is an uphill battle not worth fighting. Seems they’ve learned from Linksys and Flip Video. Instead, they are tracking the industrial side of the house. That means trying to break into some networks that are very well put together today, even if they aren’t exactly Internet-enabled.

Digital Ceiling isn’t just about the PoE lighting that was announced today. It’s a framework that allows all other kinds of dumb devices to be configured and attached to networks that have intelligence built in. The Constrained Application Protocol (CoaP) is designed in such a way as to provide data about a great number of devices, not just lights. Yet lights are the launch Continue reading

The Myth of Chargeback

Cash register by the National Cash Register Co., Dayton, Ohio, United States, 1915.

Imagine a world where every aspect of a project gets charged correctly. Where the massive amount of compute time for a given project gets labeled into the proper department and billed correctly. Where resources can be allocated and associated to the projects that need them. It’s an exciting prospect, isn’t it? I’m sure that at least one person out there said “chargeback” when I started mentioning all these lofty ideas. I would have agreed with you before, but I don’t think that chargeback actually exists in today’s IT environment.

Taking Charge

The idea of chargeback is very alluring. It’s been on slide decks for the last few years as a huge benefit to the analytics capabilities in modern converged stacks. By collecting information about the usage of an application or project, you can charge the department using that resource. It’s a bold plan to change IT departments from cost centers to revenue generators.

IT is the red headed stepchild of the organization. IT is necessary for business continuity and function. Nothing today can run without computers, networking, or phones. However, we aren’t a visible part Continue reading

We Are Number Two!

In my old IT life I once took a meeting with a networking company. They were trying to sell me on their hardware and get me to partner with them as a reseller. They were telling me how they were the number two switching vendor in the world by port count. I thought that was a pretty bold claim, especially when I didn’t remember seeing their switches at any of my deployments. When I challenged this assertion, I was told, “Well, we’re really big in Europe.” Before I could stop my mouth from working, I sarcastically replied, “So is David Hasselhoff.” Needless to say, we didn’t take this vendor on as a partner.

I tell this story often when I go to conferences and it gets laughs. As I think more and more about it the thought dawns on me that I have never really met the third best networking vendor in the market. We all know who number one is right now. Cisco has a huge market share and even though it has eroded somewhat in the past few years they still have a comfortable lead on their competitors. The step down into the next tier of Continue reading

The Butcher’s Bill

Watching a real butcher work is akin to watching a surgeon. They are experts with their tools, which are cleavers and knives instead of scalpels and stitches. They know how to carve the best cut of meat from a formless lump. And they do it with the expert eye of a professional trained in their trade.

Butcher is a term that is often loaded with all manner of negative connotations. It makes readers think of indiscriminate slaughter and haphazard destruction. But the real truth is that a butcher requires time and training to cut as they do. There is nothing that a butcher does that isn’t calculated and careful.

Quick Cuts

Why all the discussion about butchers? Because you’re going to see a lot more comparisons in the future when people talk about the pending Dell/EMC acquisition. The real indiscriminate cutting has already started. EMC hid an undisclosed number of layoffs in a Dec. 31 press release. VMware is going to take a 5% hit in jobs, including the entire Workstation and Fusion teams.

It’s no secret that the deal is in trouble right now. Investors are cringing at some of the provisions. The Virtustream spin out was rescinded after Continue reading

The Tortoise and the Austin Hare

Dell announced today the release of their newest network operating system, OS10 (note the lack of an X). This is an OS that is slated to build on the success that Dell has had selling 3rd party solutions from vendors like Cumulus Networks and Big Switch. OS10’s base core will be built on an unmodified Debian distro that will have a “premium” feature set that includes layer 2 and layer 3 functionality. The aim to have a fully open-source base OS in the networking space is lofty indeed, but the bigger question to me is “what happens to Cumulus”?

Storm Clouds

As of right this moment, before the release of Dell OS10, the only way to buy Linux on a Dell switch is to purchase it with Cumulus. In the coming months, Dell will begin to phase in OS10 as an option in parallel with Cumulus. This is especially attractive to large environments that are running custom-built networking today. If your enterprise is running Quagga or sFlow or some other software that has been tweaked to meet your unique needs you don’t really need a ton of features wrapped in an OS with a CLI you will barely use.

So Continue reading

My Thoughts On The Death Of IP Telephony

A Candlestick Phone (image courtesy of Wikipedia)

Greg Ferro (@EtherealMind) posted a thought provoking article about collaboration in his Human Infrastructure magazine (which you should be reading). He talks about the death of IP Telephony and the rise of asynchronous communications methods like Slack. He’s got a very interesting point of view. I just happen to disagree with a few of his assertions.

IP Telephony Is Only Mostly Dead

Greg’s stance that IP Telephony is dead is a bit pointed to say the least. He is correct that the market isn’t growing. It is also true that a great number of new workers entering the workforce prefer to use their smartphones for communications, especially the asynchronous kind. However, desk phones are a huge part of corporate communications going forward.

IT shops have a stilted and bizarre world view. If you have a workforce that has to be mobile, whether it be for making service calls or going to customer sites for visits, you have a disproportionately large number of mobile users for sure. But what about organizations that don’t have large mobile populations? What about financial firms or law offices or hospitals? What about retail organizations? These Continue reading

It’s Time For IPv6, Isn’t It?

I made a joke tweet the other day:

It did get lots of great interaction, but I feel like part of the joke was lost. Every one of the things on that list has been X in “This is the Year of X” for the last couple of years. Which is sad because I would really like IPv6 to be a big part of the year.

Ars Technica came out with a very good IPv6-focused article on January 3rd talking about the rise in adoption to 10% and how there is starting to be a shift in the way that people think about IPv6.

Old and Busted

One of the takeaways from the article that I found most interesting was a quote from Brian Carpenter of The University of Aukland about address structure. Most of the time when people complain about IPv6, they say that it’s stupid that IPv6 isn’t backwards compatible with IPv4. Carpenter has a slightly different take on it:

The fact that people don’t understand: the design flaw is in IPv4, which Continue reading

Doing 2016 Write

It’s the first day of 2016 and it’s time for me to look at what I wanted to do and what I plan to accomplish in the coming 366 days. We’ve got a busy year ahead with a leap day, the Olympics, and a US presidential election. And somewhere in the middle of all that there’s a lot of exciting things related to tech.

2015 In Rewind

Looking back at my 2015 goals, I think I did a fairly good job:

• Writing in Markdown – Read about it all here
• Blog themes – I really did look at quite a few themes and tried to find something that worked the way I wanted it to work without major modifications. What I finally settled on was a minor font change to make things more readable. For me, form has never been more important than function, so I spend less time worrying about how my blog looks and much more time focusing on how it reads.
• Cisco Live Management – Didn’t quite get this one done. I wanted to put up the poll for the big picture at the end and I managed to miss it this year! The crew Continue reading

My Markdown Adventure

It was almost a year ago that I set forth the idea to start writing all my blog posts in Markdown. I’ve been doing my best to keep up with that throughout the year and now I’m fifty Markdown posts into my goal. How is it working out so far?

Markdown Mindset

Learning to write in Markdown took some adjustment. Before, I had just used the web editor or the occasional HTML editing suite to write my posts. Most of the HTML was hidden. With Markdown, you have to think about what you’re going to do before you start writing it. Where are the links going to appear? How is your post going to be organized? Putting a bit more thought into your post gives you more structure to your thoughts. That’s something that’s helped my writing a bit.

The table layout for the 2015 Cisco Live Twitter List really wasn’t all that difficult either. Once I put the initial code together, it was just a simple copy/paste job after that. I’m toying with the idea of putting all my notes into Markdown as well. But given how terrible I am with taking typed notes that may not happen.

Editing Continue reading

Keeping IT Up With The Joneses

We’ve all been in that meeting. We’re learning the important facts about a company and their awesome technology. We think we’ve got a handle of the problem they’re solving and how we can apply it to our needs. And then…BAM! Our eyes are assaulted by a billboard full of company logos. We’re told how every one of these companies think that this product or solution is awesome. And because they think it’s awesome and bought it, you should think it’s awesome as well and buy it too.

Do As They Do

This particular exchange in a presentation has a term: the NASCAR slide. When I came up with the term years ago during a Tech Field Day presentation, I referred to the fact that the slide was covered by all of the logos of customers and sponsors, not unlike the side of a NASCAR race car or the coveralls worn by the drivers. It turned the presentation into a giant neon sign signaling all the companies that bought the solution.

Vendors love to tell you who their customers are. They love holding those solution bidding wins over their competitor’s heads and informing the populace that a company like Victoria’s Continue reading

Share And Share Alike

Every once in a while, I like to see who is clicking through to my blog. It helps me figure out what’s important to write about and who reads things. I found a recent comment that made me think about what I’m doing from a different perspective.

Build Slides Are Evil

PowerPoint is a necessary evil. No program allows us to convey as much information in a short amount of time. PowerPoint is almost a requirement for speaking in front of groups. Information can be shown in a very effective manner for audiences of five or five hundred. But PowerPoint also allows presenters to do some very silly things that impact our ability to learn.

Not Built In A Day

The biggest offense in the land of PowerPoint is the build slide. Build slides are those that have elements that must be layered together in order to show the complete picture. In some cases, build slides have complex graphic overlays with many different elements. They may have clip art overlays. But build slides can also be simple bullet points that appear one at a time in a list. The key is that all the parts of the slide must progress in series to “build” the whole thing.

Build slides look very awesome. They provide the appearance of motion and give a movie-like quality to a static presentation. And they often take up a large amount of time during the creation process. But they are almost always unnecessary.

When built properly, Continue reading

The Marriage of the Ecosystem

A recent discussion with Greg Ferro (@EtherealMind) of Packet Pushers and Nigel Poulton (@NigelPoulton) of In Tech We Trust got me thinking about product ecosystems. Nigel was talking about his new favorite topic of Docker and containers. He mentioned to us that it had him excited because it felt like the good old days of VMware when they were doing great things with the technology. That’s when I realized that ecosystems aren’t all they are cracked up to be.

Courting Technology

Technology is a huge driver for innovation. New ideas are formed into code that runs to accomplish a task. That code is then disseminated to teams and built upon to create toolsets to accomplish even more tasks. That’s how programs happen. Almost every successful shift in technology starts with the courtship of focused code designed to accomplish a simple task or solve a quick problem.

The courtship evolves over time to include other aspects of technology. Development work extends the codebase to accept things like plugins to provide additional functionality. Not core functions though. The separation comes when people want to add additional pieces without compromising the original program. Bolting additional non-core pieces on Continue reading

A Voyage of Discover-E

I’m very happy to be attending the first edition of Hewlett-Packard Enterprise (HPE) Discover in London next week. I say the first edition because this is the first major event being held since the reaving of HP Inc from Hewlett-Packard Enterprise. I’m hopeful for some great things to come from this.

It’s The Network (This Time)

One of the most exciting things for me is seeing how HPE is working on their networking department. With the recent news about OpenSwitch, HPE is trying to shift the way of thinking about a switch operating system in a big way. To quote my friend Chris Young:

Vendors today spend a lot of effort re-writing 80% of their code and focus on innovating on the 20% that makes them different. Imagine how much further we’d be if that 80% required no effort at all?

OpenSwitch has some great ideas, like pulling everything from Open vSwitch as a central system database. I would love to see more companies use this model going forward. It makes a lot of sense and can provide significant benefits. Time will tell if other vendors recognize this and start using portions of OpenSwitch in their projects. But Continue reading
