Encryption protects us every day. It helps secure web browsing, online banking, and critical public services like electricity, elections, hospitals, transportation, and more.
If the G7 countries are truly committed to building a safer and equal world, then it is crucial to recognize the important role that end-to-end encryption plays in securing the Internet, their economies and their citizens.
The Internet Society and more than 30 organizations have signed an open letter calling on the G7 leaders to do just that – prioritize digital security – and not to require, coerce, or persuade device manufacturers, application, and service providers to:
Digital security is the foundation of our connected economies and societies. And digital security is underpinned by strong encryption! It ensures that data – whether that of law enforcement, banks, or everyday citizens – can only be accessed by its intended recipient. Any attempt to insert “exceptional” or “lawful” access to encrypted content provides a way for others, including criminals, to gain access. This weakens Continue reading

An open Internet is the foundation of access and innovation, where users can go where they want, when they want without discrimination. But how do we know if the Internet is truly open? As individuals, our Internet performance experience is mediated by our physical location, infrastructure, government, and Internet service providers. Yet we are largely blind to how our Internet is impacted by these systems. Without that knowledge, innovation stalls, disparity of access grows, and people become isolated from this critical piece of global infrastructure.
Measurement Lab (M-Lab), a fiscally sponsored project of Code for Science & Society, is a consortium of research, industry, and public interest partners focused on fostering, collecting, and publishing open Internet performance data. M-Lab was founded in 2008 to build a global platform designed to enable anyone to measure their Internet service using open source tools. Over ten years later, M-Lab collects over 2 million measurements per day worldwide and has become a trusted source of open data and tools to gather and understand Internet infrastructure from the consumer perspective. Cities and municipal governments; national regulators and government agencies; academics and researchers; ISPs, network operators, and companies; civil society and advocacy organizations; and the Continue reading

On Wednesday we took a closer look at the Networking Automation track. Soon you will be able to start building out your schedule for AnsibleFest, so we want to help you figure out what tracks and sessions will be best for you! We talked with Track Lead Jake Jackson to learn more about the Getting Started track and the sessions within it.
Who is this track best for?
This track is best for people who are new to Ansible, whether that is in application or in concept. Many of these breakout sessions are introductory in nature for people who want to learn more about Ansible and how it works.
What topics will this track cover?
This track will cover several topics. It includes introductions to Ansible and Ansible Tower, and a deeper dive into Ansible inventories. It also discusses bite-size ways to automate and manage Windows the same way you would linux. There will also be a session that introduces using Ansible in CI and analyzing roles.
What should attendees expect to learn from this track?
Attendees can expect to learn the basics of Ansible and Ansible Tower from this track. They Continue reading
Service mesh is fast becoming such a vital part of the infrastructure underlying microservices and traditional applications alike that every industry player must have an offering in the space. Because a variety of differentiated service meshes and service mesh services are emerging, it has become clear that interoperability between them will be critical for customers seeking to interconnect a wide variety of workloads.
With that in mind, we are excited to share that VMware has partnered with Google Cloud, HashiCorp, and Pivotal on an open source project for service mesh interoperability. This initiative will facilitate federation of service discovery between different service meshes of potentially different vendors. Through an API, service meshes can be interconnected to deliver the associated benefits of observability, control, and security across different organizational unit boundaries, and potentially across different products and vendors. The project will soon be opened to the community, and anyone interested in contributing to this effort can do so on GitHub.
Enterprises increasingly rely on APIs to coordinate business functions that span departmental, organization or vendor boundaries. This implies reliability, operability, security and access constraints on these API calls to ensure business Continue reading
Welcome to Technology Short Take #118! Next week is VMworld US in San Francisco, CA, and I’ll be there live-blogging and meeting up with folks to discuss all things Kubernetes. If you’re going to be there, look me up! Otherwise, I leave you with this list of links and articles from around the Internet to keep you busy. Enjoy!
While it may seem like people have their cellphones glued to their hand or to their ear, the truth is that there are times when you need your hands free to attend to other tasks or activities (like driving). Having a great phone holder in your car, for instance, allows you to still use your phone even when your hands may be occupied. If you are looking for the ultimate phone holder, here are some of your best bets.
Making or taking a phone call when you are cooking, typing at your desk, or eating is something that happens on a regular basis. Having a cellphone phone holder for in your home can make multi-tasking, whether talking on the phone, doing research, or following a recipe, much easier.
We recommend the Lamicall phone holder, which comes with the Lamicall phone dock. It has a low center of gravity (so your smartphone won’t tip over), rubber cushions to protect your phone from scratches, holds all phones 14mm or less, and is compatible with all phones 6 to 8 inches. The phone stand comes in black, red, silver, or gray.
Whenever you’re discussing a complex topic it’s worth adhering to two principles: (A) identify the challenges you’re trying to solve and (B) start as simple as you can and add complexity later.
We did exactly that in the Introducing Networking Challenges part of How Networks Really Work webinar. We started with the simplest possible case of two computers connected with a cable… and even there identified a plethora of challenges that had to be solved more than half a century ago (and still have to be solved today no matter what magic software-defined technology someone pulls out of their wizard hat).
You need free ipSpace.net subscription to watch the video, or a paid ipSpace.net subscriptions to watch the rest of the webinar.
Learning to prove theorems via interacting with proof assistants Yang & Deng, ICML’19
Something a little different to end the week: deep learning meets theorem proving! It’s been a while since we gave formal methods some love on The Morning Paper, and this paper piqued my interest.
You’ve probably heard of Coq, a proof management system backed by about 30 years of research and developed out of INRIA. Here’s how the Coq home page introduces it:
Coq is a formal proof management system. It provides a formal language to write mathematical definitions, executable algorithms and theorems together with an environment for semi-interactive development of machine-checked proofs.
Certified programs can then be extracted to languages like OCaml, Haskell, and Scheme.
In fully automated theorem proving (ATP), after providing a suitable formalism and a theorem, the goal is to be able to push a button and have the system prove that the theorem is true (or false!). The state-of-the-art in ATP is still some way behind human experts though it two key areas: the scale of systems it can tackle, and the interpretability of the generated proofs.
What a typical theorem prover does… is to prove by resolution refutation: it Continue reading
