Video: Routing over VXLAN
Even though I wrote about the challenges of routing from VXLAN VNI to VLAN segment on a certain popular chipset a while ago, many engineers obviously still find the topic highly confusing (no surprise there, it is).
Maybe a video is worth a thousand words ;) – I published the part of recent VXLAN webinar where I described the issue in as many details as I could.
No, the CIA isn’t stealing Apple’s secrets
The Intercept news site by Glenn Greenwald is activism rather than journalism. Their stories don't reference experts knowledgeable about subjects, but only activists who are concerned about the subjects. This was demonstrated yet against in their piece claiming "The CIA Campaign to Steal Apple's Secrets". Yes, the Snowden documents are real, but pretty much everything else is made up.Here's the deal. Terrorist leaders use iPhones. They are a status symbol, and status symbols are important to leaders. Moreover, since Apple's security is actually pretty good, terrorists use the phones for good reason (most Android devices suck at security, even the Blackphone).
When CIA drones bomb a terrorist compound, iPhones will be found among the bodies. Or, when there is a terrorist suspect coming out of a dance club in Karachi, a CIA agent may punch them in the face and run away with their phone. However, it happens, the CIA gets phones and wants to decrypt them.
Back in 2011 when this conference happened, the process of decrypting retrieved iPhones was time consuming (months), destructive, and didn't always work. The context of the presentation wasn't that they wanted to secretly spy on everyone's phones. The context was Continue reading
IPv4 QoS Markings Calculator
This is a quick calculator I came up that I could use in the CCIE lab to translate between various IPv4 header QoS markings. As long as I could remember how to draw out the calculator, all I had to do was some basic math and I could translate between markings quite easily.
Establishing the Big Data Connection
Many network vendors will tell you that their network equipment is built for Big Data. However, once deployed, do you have enough Big DataDocker Project’s 2nd Birthday Party Extensions & Online
In case you missed it, we recently announced that we’re organizing a global open-source-a-thon to celebrate the Docker project’s 2nd birthday. Thanks to overwhelming response and support, the event series is expanding to both online and community events! Online From … ContinuedTechnology Short Take #49
Welcome to Technology Short Take #49 (also known as Distraction-as-a-Service)! I have here for your reading pleasure an eclectic collection of links and articles from around the web, focusing on data center-related technologies. Here’s hoping you find something useful. Bring on the content!
Networking
- I love this post from Matt Oswalt on five next-gen skills for networking pros. I highly recommend you read the entire post, but in short the five skills Matt recommends are software skills (which includes configuration management and software development tools like Git), Linux, deep protocol knowledge, hypervisor and container networking, and IPv6. What’s really interesting to me is the (completely uncoordinated) alignment between Matt’s list of skills for networking pros and the list I provided to virtualization pros in a series of recent VMUG presentations (refer to slide 15, but the list is software development basics, Linux, automation/orchestration, and public cloud services). What does this mean? It tells me that some skills—specifically, Linux, automation/configuration management, software development concepts—are going to be essential for all new IT pros in the near future. If you want to stay relevant, regardless of your current “silo,” it’s time to evolve.

Are We The Problem With Wearables?
Something, Something, Apple Watch.
Oh, yeah. There needs to be substance in a wearable blog post. Not just product names.
Wearables are the next big product category that is driving innovation. The advances being made in screen clarity, battery life, and component miniaturization are being felt across the rest of the device market. I doubt Apple would have been able to make the new Macbook logic board as small as it is without a few things learned from trying to cram transistors into a watch case. But, are we the people sending the wrong messages about wearable technology?
The Little Computer That Could
If you look at the biggest driving factor behind technology today, it comes down to size. Technology companies are making things smaller and lighter with every iteration. If the words thinnest and lightest don’t appear in your presentation at least twice then you aren’t on the cutting edge. But is this drive because tech companies want to make things tiny? Or is it more that consumers are driving them that way?
Yes, people the world over are now complaining that technology should have other attributes besides size and weight. A large contingent says that battery life is Continue reading
