Back By Popular Demand – Docker Pals Is Coming To Barcelona!

At DockerCon Copenhagen we launched the Docker Pals program in order to connect attendees and help them make the most out of their trip to DockerCon. Attending a conference by yourself can be intimidating and we don’t want anyone to feel that way at DockerCon! Pals get matched with a few others who are new (the “Pals”), and someone who knows their way around (the “Guide”) so that you will know someone before you arrive at the conference. So, DockerCon veterans, please consider signing up to be a Guide and help welcome those newer to DockerCon to the amazing Docker community. Participating gives you the opportunity to learn even more, grow an even bigger network, and have even more fun!

Here’s what Pals had to say:

“Docker Pals was an excellent opportunity to meet new Docker Captains and Community Leaders who are open to engaging with container enthusiasts of all skill levels, specialities and backgrounds. I would certainly take advantage of the program again, and volunteer to be a Guide next year.” – Jackie Liu

“I was able to learn and understand how Docker is used in real time and in production with my fellow Docker Pal.” – Continue reading

BrandPost: It’s Time to Think Outside the Router

“Turn Me Loose” I finally delivered four large boxes of CDs to my local library – my collection of nearly 1,000 titles, some as old as 33 years, like my Loverboy CD, when I acquired them in back in 1985. And back in 1985, or maybe 1986, I did a similar uncluttering with my cassettes and vinyl (except for a few select albums like an original release of Dark Side of the Moon).Music has gone from 12” vinyl to more compact cassette tapes to even more compact CDs and now streaming services that connect listeners to music anywhere, anytime. Just as music technology has changed through the years to provide more flexibility on how music is consumed, the application consumption model has changed, too. The “job of the WAN” has always been to connect users to applications, but wide area networking (WAN) technology based on conventional branch routers has not kept up to provide the optimal means of connecting to them.To read this article in full, please click here

Industrial IoT faces big challenges

Future cellular Internet of Things (IoT) networks are going to be expected to deliver much lower latency and significantly higher reliability. Getting to that point, however, must be a step-by-step approach, said a telco equipment executive at Mobile World Congress Americas earlier this month.“Doing one at a time is not so difficult, but doing both at the same time is a challenge,” said Jawad Manssour, head of Networks Portfolio Management at Product Area Networks with equipment maker Ericsson, during a presentation at the conference.Ericsson is one of the world’s big three principal base station and cellular equipment vendors, along with Huawei and Nokia. Mobile network providers Sprint and Ericsson recently announced that they are building a distributed virtualized core IoT network and an IoT operating system.To read this article in full, please click here

Don’t Miss The Latest Module In Our Certified Ethical Hacking v10 Technology Course!

Module 9 is here! Tune into Josue Vargas’s newest video – Certified Ethical Hacking: Denial of Service to learn about DoS and DDoS attacks and how to prevent them.

About the Course

DoS and DDoS are disruptive attacks meant to bring a server or network out of operation. You might have seen some of this in the news, especially as related to hacktivism (people who hack for a cause). A DDoS attack can be a big financial hit on an organization. In this module you will learn how this type of attack is accomplished and even how it can be done stealthily. As an ethical hacker you will get the point of view of the attacker, as usual, but you will also learn how to protect your organization from this type of event using the right tools and strategies.

Cisco unearths 13 ‘High Impact’ IOS vulnerabilities you need to patch now

Cisco today exposed 13 vulnerabilities in its IOS and IOS XE switch and router operating software that the company said should be patched as soon as possible.The vulnerabilities were detailed in Cisco’s twice-yearly dump of IOS exposures. All have a High Impact security rating, and fixes should be evaluated by users quickly.[ Also see Invaluable tips and tricks for troubleshooting Linux. ] The company said this particular batch of issues could let an attacker gain elevated privileges for an affected device or cause a denial of service (DoS) on an affected device.To read this article in full, please click here

Worth Reading: Persistent DNS connections

For decades, the Domain Name System (DNS) has been based on a connectionless semantic: a client sends its query as a single User Datagram Protocol (UDP), and it receives a single UDP datagram with the response. This very simple communication model, along with efficient caching and clear administrative boundaries, is what allowed the DNS to scale and successfully adapt to an ever-increasing demand. —Baptiste Jonglez @APNIC

Building a Community LTE Network in Bokondini, Indonesia

As part of our work in the University of Washington’s Information and Communications Technology for Development (ICTD) Lab, we recently spent four weeks in Bokondini, a village in the Papuan Highlands. During our time in Bokondini, we helped some community members extend Internet access throughout the village via a community LTE network, using a technology stack that we call CoLTE (for Community LTE).

The Area and Background

Bokondini is a small village (population ~1,500) in the Baliem Valley, a mountainous region located in the highlands of Indonesian Papua. The Papuan Highlands are a famously rugged, remote, and hard-to-cover area, and many inhabitants of the region live without any form of telecommunications whatsoever. Infrastructure in Bokondini is a remarkably ad-hoc process; for example, electricity comes from a small set of solar panels and a micro hydro generator, and tends to shut off between the hours of 9pm and 6am.

Bokondini’s current relationship to the Internet revolves primarily around the local school. The community pays for a small (1Mbps) satellite Internet connection that terminates at the local elementary school, where it’s used to provide WiFi coverage to teachers on the school campus. Coverage is extended to a few other houses in Continue reading

Forget ‘smart homes,’ the new goal is ‘autonomous buildings’

In 2018, the concept of a smart building is no longer surprising. With the rise of the Internet of Things (IoT), so-called smart buildings and homes are everywhere, providing various degrees of intelligent management and control of various building systems, including lighting, HVAC, communications, and security. In most cases, however, those “smart” capabilities are still relatively limited, don’t always work together, and require a significant amount of human attention to function.Dwight Stewart, founder and CTO of 5-year-old Power-over-Ethernet (PoE) vendor Igor, dreams of something much bigger and better. He sees the firm’s new Nexos smart building platform as the first step toward his vision of truly autonomous buildings.To read this article in full, please click here

Introducing Cloudflare Registrar: Domain Registration You Can Love

Introducing Cloudflare Registrar: Domain Registration You Can Love
Introducing Cloudflare Registrar: Domain Registration You Can Love

“I love my domain registrar.” Has anyone ever said this? From before Cloudflare even launched in September 2010, our early beta customers were literally begging us: "Will you please launch a registrar too?!" Today we're doing just that, launching the first registrar we hope you’ll be able to say you love. It's built around three principles: trust, security, and always-fair pricing. And it’s available to all Cloudflare customers.

Needing Secure Domain Registration Ourselves

Cloudflare has actually run a registrar for some time. Like many of our best products, it started by solving an internal issue we had. Cloudflare has several mission-critical domains. If the registration of these domains were ever compromised, it would be, in a word, bad.

For years, we worked with our original domain registrar to ensure these domains were as locked down as possible. Unfortunately, in 2013, a hacker was able to compromise several of the systems of the registrar we used and come perilously close to taking over some of our domains.

That began a process of us looking for a better registrar. Unfortunately, even the registrars that charge hefty premiums and promise to be very secure turn out to have pretty lousy security. Continue reading
