Four state AGs sue to block US decision to cede key internet role

A judge in Texas has fixed for Friday the hearing in a suit filed by four state attorneys general against a decision by the U.S. to transfer by month end oversight of some key internet technical functions to a multistakeholder body.The attorneys general of Arizona, Oklahoma, Nevada and Texas filed late Wednesday a suit asking the federal court for a temporary restraining order and preliminary injunction on the proposed transfer of the Internet Assigned Numbers Authority (IANA) functions to the Internet Corporation for Assigned Names and Numbers.ICANN, under contract with the Department of Commerce, administers the IANA functions, which include responsibility for the coordination of the DNS (Domain Name System) root, IP addressing, and other internet protocol resources. The National Telecommunications and Information Administration (NTIA), an agency within the Commerce Department, said last month it will go ahead with its plan to transfer supervision of the IANA functions to a multistakeholder body on Oct. 1, in line with a plan first announced in March 2014.To read this article in full or to leave a comment, please click here

How to get started with widgets in iOS 10

iOS 10 has turned your iPhone’s screen into a new hub for widgets—just swipe left on the lock page or home screen to check it out. But what even are widgets? Just think of them as app extensions or glances that offer you quick, digestible information without you having to actually open a single app. You can even see your widgets without unlocking your iPhone, making it either really convenient or potentially invasive.Widgets are perfect for checking the weather, your calendar, and the battery percentages on your connected devices. But widgets are also great for performing common tasks with as few taps as possible, like calling your best friend or Shazaming a song at a coffeeshop. The level of information and functionality varies, so you really have to try them out and see what works best for you. Here’s a few tips on how to get started with widgets in iOS 10.To read this article in full or to leave a comment, please click here

IDG Contributor Network: The Emergency Alert System test: Lesson learned, catastrophe averted

If you were watching TV at 2:20 p.m. EDT, Wednesday, Sept. 28, you would have heard and seen a test of the Emergency Alert System. You might not have thought much about it, as similar tests have been done in the past.What made this test different was that it was a retest of a failed EAS test conducted five years ago. A live code was used to activate a national Emergency Action Notification (EAN) message that was broadcast. Five years ago, the test failed—some heard audio but saw no text, while some saw text but heard no audio. On Wednesday, the test was a success—the audio and text were successfully transmitted.To read this article in full or to leave a comment, please click here

Distributed On-Demand Network Testing (ToDD) with Matt Oswalt

In March 2016 my friend Matt Oswalt announced a distributed network testing framework that he used for validation in his network automation / continuous integration projects. Initial tests included ping and DNS probes, and he added HTTP testing in May 2016.

The project continues to grow (and already got its own Github and documentation page) and Matt was kind enough to share the news and future plans in Episode 63 of Software Gone Wild.

To ask questions about the project, join the Todd channel on networktocode Slack team (self-registration at slack.networktocode.com)

Introducing Dedicated SSL Certificates

When we launched Universal SSL in September 2014 we eliminated the costly and confusing process of securing a website or application with SSL, and replaced it with one free step: sign up for Cloudflare.

When you complete the sign-up process, we batch your domain together with a few dozen other recently signed-up domains, and fire off a request to one of our Certificate Authority (CA) partners. The CA then sends us back a shared certificate covering the root (e.g. example.com) and top-level wildcard (e.g. *.example.com) of your domain, along with the hostnames of the other customers in the request. We then package this shared certificate with its encrypted private key and distribute it to our datacenters around the world, ensuring that your visitors’ HTTPS sessions are speedy no matter where they originate.

Since that process was created, we have used it to secure millions of domains with free Universal SSL certificates and helped make the Internet a faster and more secure place.

More control and personalization

But along the way we heard from customers who wanted more control over the certificates used for their domains. They want Continue reading

LXLE: A Linux distro to give new life to old hardware

I’ll bet that somewhere, perhaps at home and most likely at work, you’ve got some old hardware lying around. What to do with it? It still works but what’s it running? Windows XP? Vista? Windows 7 Starter or Home Basic?Yep, you’re stuck on some old version of Windows but moving that machine up to a newer version of Windows could be tricky ‘cause one or more of those old graphics cards and printer drivers have probably have fallen out of the update cycle. Even if those subsystems are still available, you’ll still have a problem as the newer OSs' are pretty much guaranteed to suck the life out of old processors with the result that performance and therefore usability will be marginal at best.

iPhone 8 to feature glass casing and stainless steel frame

Aside from a completely new form factor, Apple’s 2017 iPhone -- a device that will reportedly be called the iPhone 8 – will also employ some interesting new materials. According to a new research report from reputed analyst Ming-Chi Kuo, Apple is planning to use a glass casing on its next-gen iPhone model.Kuo’s report, per MacRumors, adds that the iPhone 8’s glass casing will be strengthened by a stainless steel frame, at least on the higher-end models. Metal frame can be stainless steel or aluminum, with former more likely for high-end models. As all-glass casing is not possible at present given technological bottlenecks, a metal frame surrounding the edge is necessary for reinforced structure design. As stainless steel has a better look than aluminum and costs more, we expect only high-end new iPhone models to come with a stainless steel frame next year.To read this article in full or to leave a comment, please click here

ToDD Has Moved!

ToDD has been out in the wild for 6 months, and in that time I’ve been really pleased with it’s growth and adoption. Considering this was just a personal side-project, I’ve been blown away by what it’s doing for my own learning experiences as well as for the network automation pipelines of the various folks that pop onto the slack channel asking questions.

For the last 6 months I’ve hosted ToDD on my personal Github profile. It was a good initial location, becuase there really was no need at the time to do anything further.

However, as of tonight, ToDD’s new permanent location is https://github.com/toddproject/todd. Read on for some reasons for this.

Native Testlets

One of the biggest reasons for creating the “toddproject” organization came about when I started rewriting some of the testlets in Go. These are called native testlets and the intention is that they are packaged alongside ToDD because they’re useful to a very wide percentage of ToDD’s userbase (in the same way the legacy bash testlets were).

For this reason, I created the “toddproject” organization, and once that was done, it made a lot of sense to move ToDD there as well.

Rewriting the legacy Continue reading

Ga-ga for goggles: Augmented & virtual reality bring the masses to Harvard

Wednesday was a big day for goggles in my life: I spent the afternoon at Harvard University's Innovation Labs, where hundreds of people tried on the latest virtual and augmented reality headsets, then I watched the Boston Red Sox on TV that night as they donned ski goggles meant to keep champagne from spraying into their eyes as they awkwardly celebrated winning the American League East title despite blowing a game to the Yankees in the bottom of the 9th inning.Coincidentally, the Red Sox baseball team was among the exhibitors showing off their virtual reality application, which enables fans to step into the batting cage to get a feel for what it's like to be up close to David Ortiz while he's hitting or David Price while he's pitching.  The Sox offer their Samsung Gear VR experience both at Fenway Park and at community events, such as this Hubweek event that took place at Harvard Innovation Lab.To read this article in full or to leave a comment, please click here

What is reliability in networking ?

What is reliability in networking ? Why reliability is an important design tool ? I will provide the answers of these questions with the examples in this post. Reliability is within the reasonable amount of time, which depends on the application type and architecture, delivering the legitimate packets from source to destination. This time is […]

Spanning Tree Best Practices

Spanning Tree Protocol (STP) is a control plane mechanism for Ethernet. It is used to create a Layer 2 topology (a tree) by placing the root switch on top of the tree. Since classical Ethernet works based on data plane learning and Ethernet frames don’t have TTL for loop prevention, loops are prevented by the […]

Keystone Keynotes

keystonekeynotepatrol

My distaste for keynotes is well known. With the possible exception of Justin Warren (@JPWarren) there may not be a person that dislikes them more than I do. I’ve outlined my reasons for it before, so I won’t go into much depth about it here. But I do want to highlight a few recent developments that are doing a great job of helping me find new things to dislike.

Drop The “Interviews”

When you walk into a keynote ballroom or arena and see two comfy chairs on stage, you know what’s coming. As someone told me recently, “This is when I know the next hour is going to suck.” The mock interview style of keynote speech is not good. It’s a thinly-veiled attempt to push an agenda. Perhaps it’s about innovation. Or transformation. Or some theme of the conference. Realistically, it’s mostly a chance for a keynote host (some form of VP) to provide forced banter with a celebrity that’s being paid to be there.

These “interviews” are rarely memorable. They seem self serving and very plastic. The only ones that even stand out to me in recent memory are the ones that went off the Continue reading
