What Silicon Valley doesn’t say in its Trump attack

Donald Trump will be "a disaster for innovation," according to some of Silicon Valley's technology leaders. But the innovation disaster they're warning of is already ongoing in America.U.S. support for research is declining, and just last month China surpassed the U.S. in number of supercomputers on the Top500 list. Both countries are now in a race to build exascale systems (1,000 petaflops), a competition the U.S. is almost certain to lose based on published roadmaps.The U.S. has set 2023 as its goal for exascale; China is aiming for 2020.To read this article in full or to leave a comment, please click here

Microsoft downsizes OneDrive accounts, enforces restrictions

Users of Microsoft's OneDrive have begun receiving notifications that their storage allotments have already, or will soon be, reduced to 5GB.The emails to OneDrive account holders were the first step in a process that Microsoft announced last year as part of a broader reduction in cloud-based storage allowances. The free amount was to be lowered from 15GB to 5GB, and another 15GB that many had -- the photograph-specific "Camera Roll" bonus that had been given to any who asked -- was to be erased.To read this article in full or to leave a comment, please click here

Windows as a Service: What’s it mean?

The idea that Microsoft would eventually unveil a subscription licensing model for Windows 10 -- the so-called Windows-as-a-Service (WaaS) model -- has been bandied about for a while now. This week Microsoft made that idea real, but only for enterprise customers. At its Worldwide Partner Conference (WPC) in Toronto, the company announced the details of Windows 10 Enterprise E3 and Windows Enterprise E5.To read this article in full or to leave a comment, please click here(Insider Story)

Wearables could compromise corporate data

As smartwatches and other wearables gain popularity, experts are warning of potential data security risks in workplaces.Some employees have begun connecting their personal smartwatches with corporate Wi-Fi networks, which could mimic the problems caused when personal smartphones started showing up at work several years ago. That earlier bring-your-own-device (BYOD) trend fostered an explosion of software products from various vendors for managing devices securely, alongside laptops and desktops.As wearables begin to flood the workplace, the risk to employers could begin to look like "BYOD on steroids," said Peter Gillespie, an attorney at Fisher Phillips, a national labor and employment law firm representing employers.To read this article in full or to leave a comment, please click here

Tesla asked to brief Senate committee on fatal car crash

Tesla Motors has been asked by a U.S. Senate Committee to brief it on the circumstances leading to a fatal accident that killed the driver of a Tesla Model S, while the vehicle’s Autopilot driver-assistance software was turned on.The request by the committee on Thursday comes on the same day that Consumer Reports, a product-testing and rating nonprofit, called on Tesla to disable hands-free operation in its cars until it can be made safer. Though advanced active safety technology in vehicles could eventually make roads safer, today "we're deeply concerned that consumers are being sold a pile of promises about unproven technology,” said Laura MacCleery, vice president of consumer policy and mobilization for the organization, in a statement.To read this article in full or to leave a comment, please click here

For Your Reading List: Re-Imagining Productive Work with Office 365 by Michael Sampson

Michael Sampson’s latest book, Re-Imagining Productive Work with Office 365, is a “must read” if you are currently using or planning to use Office 365. Michael is a brilliant author and approaches his overview of Office 365 not from the perspective of the individual technology elements, but from the perspective of the activities that “information workers” do every day: Storing and sharing files Profiling employee expertise Co-authoring documents Managing meetings Holding discussions Running team projects Thinking productively The focus on business activities instead of specific technologies provides a very practical way of consuming the information in this very well researched book. It will help you understand which aspect of Office 365 to use in a variety of business use cases and how you can best engage your colleagues to be successful with this technology suite. Though the features and capabilities of Office 365 are updated almost too quickly to be incorporated into a book, Michael has found a way to make sure the book’s content stays relevant by indicating where future updates will improve or enhance the experiences he describes.To read this article in full or to leave a comment, please click here

INE’s CCIE DCv2 Topology & Content Updates

Now that Cisco Live US 2016 is winding down, we’re going full steam ahead with our CCIE Data Center version 2.0 Blueprint updates.  For those of you that haven’t seen it, my live blog of the CCIE DCv2 Techtorial @ Cisco Live US 2016 can help to answer some additional questions about the exam content and format changes.

Some important upcoming dates in the short term are:

For those of you that have already spent time working on the DCv1 blueprint and are transitioning to DCv2, I would highly recommend to check out the online class the week of August 1st.  I’ll mainly be focusing on the technologies that changed in the blueprint, such as Nexus 9k, ACI, BGP EVPN signaled VxLAN, etc.

Microsoft’s overseas privacy battle may be far from over

Privacy advocates, especially those outside the U.S., can rest a little easier now.  A federal court has rebuked the U.S. government’s attempt to access emails stored on a Microsoft server in Ireland.But the legal battle may be far from over. Thursday’s ruling could affect how the U.S. conducts surveillance over suspected criminals and terrorists overseas, so expect the government to appeal, said Roy Hadley, a lawyer at Thompson Hine who studies cybersecurity issues.“There’s a fine line between privacy and national security,” he said. “And it’s a difficult line to walk.”To read this article in full or to leave a comment, please click here

Telecom industry hails FCC move to open 5G spectrum

Eleven gigahertz of high-frequency spectrum is now available for use in mobile broadband technologies, after the FCC on Thursday created the Upper Microwave Flexible Use service in the 28GHz, 37GHz and 39GHz band, along with a new unlicensed band, even higher up the spectrum, in the 64-71GHz range.The move was greeted with delight from the U.S. telecom industry, which said that the opening of new spectrum is a critical step on the road to 5G wireless technology. The millimeter-wave bands – those between 30GHz and 300GHz – are central to the development of 5G, and the U.S. is now the first country to designate those frequencies for commercial use.To read this article in full or to leave a comment, please click here

BRKRST-3014 – Policy, Complexity, and Modern Control Planes


Presented by: Russ White, LinkedIn

Networks are complex. How do we measure complexity? How do we measure scale? What’s the unit of measure?

You can’t “solve” complexity.

Alderson D and J Dole “complexity in highly organized systems arises primarily from design strategies intended to create robustness to uncertainty.” There’s a point on the complexity scale where robustness actually drops. “Robust but fragile”.

Dunning Kruger effect?

What is complexity?

  • Anything you don’t understand?
  • Anything with many parts?
  • Anything with unintended consequences?
  • Something that can’t be solved; can’t be easily defined.
  • We need to develop a model to understand complex systems quickly

“If you haven’t found the trade off, you haven’t looked hard enough” — Russ

The model:

  • Ask, Why?
  • Ask ,What & How?
  • State
  • Optimization
  • [Interaction] Surface (where two components interact with each other [which could be, and often is, human on CLI])
  • Ask, This is like what? (what’s it similar to?)
  • Now matter how you’re analyzing a network (protocols, applications, whatever), you’ll find these 3 things.
  • Good examples of questions to ask for each point in different use cases

3-way trade off:

  • Quick/Cheap/Quality, or
  • State/Surface/Optimization

“Adding more state to the system should result in an increase in optimization” Continue reading
