Johannes Weber was forced to stress-test the IPv6 networks are easy to renumber nonsense and documented his test results – a must-read for everyone deploying IPv6.
He found out that renumbering IPv6 in his lab required almost four times as many changes as renumbering (outside) IPv4 in the same lab.
My cynical take on that experience: “Now that you’ve documented everything that needs to be changed, make sure it’s automated the next time ;)”
Unveiling and quantifying Facebook exploitation of sensitive personal data for advertising purposes Cabañas et al., USENIX Security 2018
Earlier this week we saw how the determined can still bypass most browser and tracker-blocking extension protections to track users around the web. Today’s paper is a great example of why you should care about that. Cabañas et al. examine the extent to which the profile Facebook builds on its users includes sensitive personal data made available to advertisers for targeting. The work was done just prior to the GPDR coming into force, which makes for very interesting timing from a legal perspective. The headline result is that it looks like Facebook is holding sensitive data on about 40% of the EU population, and that this data can be used by third-parties to target individuals in sensitive demographics and even identify them at a cost of as little as €0.015 per user.
The GDPR definition of sensitive personal data is “data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, or trade union membership, and the processing of genetic data, biometric data for the purpose of uniquely identifying Continue reading

Let’s talk about lasers! In this episode of Kernel of Truth, I asked Product Manager Brian O’Sullivan (who you’ll remember from our episode about automation) and Principal Engineer Scott Emery to join me in the recording booth and chat about optical networking. We’ll get into topics like forward error correction, the divide between data center networking engineers and optical networking engineers, Voyager and Pink Floyd. Who knew that progressive rock had anything to do with optical networking?? (It doesn’t, really, but we somehow worked it in.)
So tune in and learn why an open packet optical platform is so innovative for optical networking and telco! And make sure to subscribe to the Kernel of Truth podcast so you stay up to date on the open networking revolution — get with the future of networking so you’re not just “Another Brick in the Wall!”

In this episode of IPv6 Buzz, we examine how and why to make the transition from a dual-stack to an all-v6 world. Our guest is Veronika McKillop, network architect at Microsoft and president/chair of the UK IPv6 Council.

LTE growth coupled with the early stages of 5G deployments fueled the evolved packet core market in the second quarter of the year.
As you go through digital transformation, there are a few things to keep in mind. Here are some steps to consider for digital transformation that allows flexibility for future growth.
In 1843, Ada Lovelace published “Sketch of the analytical engine invented by Charles Babbage” in the book Scientific Memoirs. But because of her “condition” as a woman she, like many women who were pioneers in their time, was forgotten by history. Women could not access education or the sciences and, for that reason, history forgot them, just as we forgot that many women were mothers of the Internet.
“History drove us out of the digital industry, we stopped being important and a male industry was created.”
– Kemly Camacho, Sula Batsú
Every day many people ask us, where are the women? Why don’t they participate? I tell them to look at the immense number of initiatives that women are doing in Latin America and the Caribbean.
With the cold of Buenos Aires, between its tall buildings and its warm people, our friends at the Tierra Violeta Cultural Center received us after four months of planning the FemHackParty LAC. In December 2016, at the Internet Governance Forum that took place in Guadalajara, Mexico, we organized with a group of women the first FemHackParty, within the framework of 16 days of activism against violence against women. We had the chance to learn Continue reading
Now, if that isn’t a title jam-packed with buzzwords, I don’t know what is! In seriousness, though, I wanted to share how to use kubeadm to turn up a Kubernetes cluster using containerd (instead of Docker) and Cilium as the CNI plugin. I’m posting this because I wasn’t able to find a reasonable article that combined all the different threads—some posts talked about using containerd, others talked about using Cilium, and the official Kubernetes docs have examples for using kubeadm. The purpose of this post is to try to pull those threads together.
For structure and context, I’ll build upon the official Kubernetes document outlining creating highly available clusters with kubeadm. You may find it helpful to pull up that article next to this one, as I won’t be duplicating that content here. Instead, I’ll just reference additions/changes to the process in order to accommodate containerd and Cilium.
Before getting started, make sure that your systems will meet the minimum requirements for Cilium. For my testing, I used Ubuntu 16.04 with the latest HWE kernel (4.15.0-33-generic). I used a private fork of Wardroom to build the AWS AMIs with containerd and all the Kubernetes 1.11.2 Continue reading
