These are challenging times for Intel. Long – and still – the dominant chip maker in the datacenter with its battle-tested Xeon processors, the company is now seeing challenges everywhere. …

After publishing the Manual Work Is a Bug blog post, I got this feedback from Michele Chubirka explaining why automating changes in your network also increases network security:

This value is 17 here, and it shouldn’t be. Why did the get request return 17?
Sometimes the simplest questions can be the hardest to answer. As the opening sentence of this paper states:
Debugging distributed systems is hard.
The kind of why questions we’re interested in for this paper are questions of provenance. What are the causes of this output? Provenance has been studied in the context of relational databases and dataflow systems, but here we’re interested in general distributed systems. (Strictly, those where the behaviour of each node can be modelled by a deterministic state machine: non-deterministic behaviour is left to future work).
Relational databases have why-provenance, which sounds on the surface exactly like what we’re looking for.
Given a relational database, a query issued against the database, and a tuple in the output of the query, why-provenance explains why the output tuple was produced. That is, why -provenance produces the input tuples that, if passed through the relational operators of the query, would produce the output tuple in question.
One reason that won’t work in our distributed systems setting is that Continue reading

On April 1st, 2018, we announced 1.1.1.1, the fastest public DNS resolver in the world 🚀🚀🚀. Today, we are launching the 1.1.1.1 mobile app to make it incredibly easy to use 1.1.1.1 on your phone.
Any time you are on a public internet connection people can see what sites you visit. Even worse, your Internet Service Provider is very possibly selling all of your browsing history to the highest bidder. We have a tool called 1.1.1.1 which makes it easy to get a faster, more private, Internet experience, but it’s historically been too complex for many people to use, particularly on mobile devices. Today, we’re launching an app you (and everyone you know) can use to use 1.1.1.1 every time your mobile phone connects to the Internet. It’s a free, it’s easy, download it now.
We launched 1.1.1.1 on April 1st. Frankly, we’ve been blown away by how many people actually made the switch. Changing your network settings is not easy, but if our traffic amount is any indication, many of you made the effort. Continue reading
Today marks the 100th anniversary of the armistice that ended the first World War. The 1918 ceasefire re-introduced a fragile peace that had collapsed when the world failed to defend common rules and international cooperation. International security and stability are as important now as they were a century ago.
That’s why French President Emmanuel Macron and leaders from around the world are about to gather in Paris for the first Paris Peace Forum. The forum will attempt to pave a way forward for a world that is shifting and changing faster than most of us can keep up with. That change and shift, and the speed of it is enabled by the Internet.
That is why the Internet Society is participating in the Forum.
I will be in Paris to speak on a panel about creating peace in cyberspace. Cybersecurity concerns across the world are real and justified and need to be addressed. We believe that the collaborative approach that helped to drive the growth of the Internet and allows it to thrive is essential for establishing cybersecurity.
The essence of a collaborative approach is that it allows stakeholders to create a shared vision for security.
The Shared Vision

SDxCentral Weekly Wrap for Nov. 9, 2018: Cisco axes jobs; Verizon CEO Vestberg makes bold moves with restructuring; and more.
What’s in a name? NetApp says its HCI is really hybrid cloud infrastructure (not hyperconverged), but it sounds more like composable.
Xilinx is renown for its field programmable gate array (FPGA), which the company's founder invented. A purchase of Mellanox could give it additional products to sell into the data center.
Alibaba Group’s CEO said that cloud computing will be its “main business” in the future — following closely in Amazon’s footsteps.
Dish says it is building a neutral-host 5G network that customers can rent space on to deliver different types of services.
Docker containerizes Windows Server 2008; Rumors fly that Thoma Bravo will buy Symantec; CommScope buys Arris.
The software-based platform is focused on mobility network functions needed to interconnect any edge application without any upgrades to the underlying network or origin cloud.
