DockerCon Returns to Europe in 2017

DockerCon is making its return to Europe next year! DockerCon Europe will be held in the beautiful city of Copenhagen, Denmark at Bella Center Cope
copenhagen-denmark-with-datesnhagen from October 16 – October 18, 2017. We plan on opening the week on Monday, October 16 with paid trainings and workshops, then General Session will kick off the conference the morning of Tuesday October 17 and the conference will continue through Wednesday October 18.

Three reasons why we are excited about DockerCon Europe in Copenhagen

 

  • On behalf of the entire Docker team, it’s safe to say that we cannot wait to reunite with the Docker Community in Europe under one roof again! Local Docker Meetup chapters take place every week to fuel the community enthusiasm, but there is something special about coming together for DockerCon and collaborating, learning and networking as a big group.
  • Recently remodeled in 2014/2015, the Bella Center Copenhagen is an ultra-modern event space featuring Scandinavian design throughout including open space with lots of indoor greenery. Bella Center Copenhagen is also one of the most sustainable venues in the world. They practice waste sorting in 16 categories, have an 850 kW wind turbine on-site for energy, as well as Continue reading

Congress members try to grasp enormity of IoT DDoS attacks

Today I watched an interesting Energy and Commerce subcommittee hearing about “Understanding the Role of Connected Devices in Recent Cyber Attacks.” The attacks refer to when insecure IoT devices infected with Mirai malware hammered DNS provider Dyn in October.The hearing included testimony, as well as submitted prepared remarks, from Dale Drew (pdf), CSO and senior vice president of Level 3 Communications; crypto and privacy guru Bruce Schneier (pdf); and Dr. Kevin Fu (pdf), who helped shock the world years ago by saying pacemakers and implantable cardiac defibrillators were vulnerable to hackers. You can read the experts’ testimonies for specific concerns and suggestions, but this is primarily based on paraphrased commentary during the hearing.To read this article in full or to leave a comment, please click here

MikroTik RouterOS new feature – Loop Protect

 

‘Loop Protect’ – New feature in 6.37rc24

Long-time MikroTik users have been after better loop prevention mechanisms for quite a while now. Rapid STP within bridges was the only feature available up until Fall of 2016 and now MikroTik has released Rapid Spanning Tree in hardware for switched ports as well as a new Loop Protect feature that seems to serve the same function as Cisco’s Loop Guard but not utilize spanning tree to detect the loop. MikroTik’s version compares the source MAC of the loop protect frame with the MAC of the interface it is received on and if they match, it will disable the port until the timer expires and check again for the existence of a loop.

This feature was introduced in 6.37rc24 on August 31st, 2016.

http://wiki.mikrotik.com/wiki/Manual:Loop_Protect

Use cases for ‘Loop Protect’

Loop protect seems to be designed more as an edge port protocol since it physically disables the port upon detection of a loop, whereas STP will leave the port physically active but logically block traffic on that path.  Some potential use cases for enabling this feature could include:

  • Edge port on a MikroTik device facing the end subscriber equipment Continue reading

US lawmakers balk at call for IoT security regulations

The U.S. government needs to pass regulations mandating internet of things security measures before device vulnerabilities start killing people, a security expert told lawmakers.A massive distributed denial-of-service attack aided by IoT devices in October "was benign" because a couple of websites crashed, said Bruce Schneier, a veteran cybersecurity researcher and lecturer at Harvard University. But the next attack may be more dangerous.With cars, airplanes, thermostats, and appliances now connected to the internet, "there's real risk to life and property, real catastrophic risk," Schneier told two House of Representatives subcommittees Wednesday.To read this article in full or to leave a comment, please click here

The Story of Batching to Streaming Analytics at Optimizely

Our mission at Optimizely is to help decision makers turn data into action. This requires us to move data with speed and reliability. We track billions of user events, such as page views, clicks and custom events, on a daily basis. To provide our customers with immediate access to key business insights about their users has always been our top most priority. Because of this, we are constantly innovating on our data ingestion pipeline.

In this article we will introduce how we transformed our data ingestion pipeline from batching to streaming to provide our customers with real-time session metrics.

Motivations 

Unification. Previously, we maintained two data stores for different use cases - HBase is used for computing Experimentation metrics, whereas Druid is used for calculating Personalization results. These two systems were developed with distinctive requirements in mind:

Experimentation

Personalization

Instant event ingestion

Delayed event ingestion ok

Query latency in seconds

Query latency in subseconds

Visitor level metrics

Session level metrics

As our business requirements evolve, however, things quickly became difficult to scale. Maintaining a Druid + HBase Lambda architecture (see below) to satisfy these business needs became a technical burden for the engineering team. We need a solution that Continue reading

Cybersecurity fabric vs. a security platform: Fabric wins

The shift to digital has introduced several new technologies into businesses. Internet of Things (IoT), mobility, cloud and the like allow companies to become highly agile and move with speed.However, the increased agility businesses are realizing has come with a price, which is that the complexity of IT has never been higher. There are many implications to increased complexity, but the biggest is that securing the business has become more difficult.INSIDER: 5 ways to prepare for Internet of Things security threats Securing organizations used to be straight forward: Put up a big, expensive firewall at the sole ingress/egress point, and all was good. Today there are dozens or even hundreds of entry points created from an increase in the use of cloud services, mobile workers and consumer devices. Security must now be applied at the perimeter, but also in the data center, campus, cloud, branch offices and anywhere else the business might have assets or people.To read this article in full or to leave a comment, please click here

Worth Reading: IPv6 Inside LinkedIn

One person, or a small team, can install, configure, and manage a limited number of devices (servers, switches, routers, etc.) manually. In any large network, with hundreds or even thousands of devices, it gets more complicated, and you will want to start automating some of these functions. This is one dimension of scaling your infrastructure. And as teams grow, more and more people are doing the same work on the same devices, so it’s necessary to have tools that ensure knowledge is transmitted, changes are reviewed, etc. This is another dimension of scaling. —LinkedIn Engineering Blog

Beyond brainstorming: 4 cool action items hatched from Cisco ideation session

Matt Cutler, whose startup Cisco bought three years ago, found himself moving from an outfit with eight people to one with tens of thousands. He looked forward to accessing resources beyond his reach at Collaborate.com, but was wary of being able "to get stuff done" within the larger organization.One way he’s been able to get stuff done is through Cisco’s little-known Founders Forum for the entrepreneurial leaders of companies it has acquired. Passionate about the sort of modern workstyles and design thinking (and "a lot of sticky notes") he incorporated at his startup, Cutler recently volunteered to lead a break-out ideation session in an effort to extract great ideas from his peers in the Forum. That of course could be easier said than done when dealing with a large group of intelligent, highly opinionated people.To read this article in full or to leave a comment, please click here
