DockerCon Hands-on Labs now online

One of more popular activities at DockerCon is our Hands-on Labs, where you can learn to use the Docker tools you see announced on stage, or talked about in the breakout sessions. This year we had eight labs for people to work through, ranging from 20 minutes to an hour in length.

DockerCon Hands-on Labs

We’ve now moved these apps into the Docker Labs Repo so that everyone can use them. The Docker Labs Repo is where we put a bunch of learning content for people who want to learn Docker, from beginner to advanced security and networking labs.

Here are the new labs:

Continuous Integration With Docker Cloud

In this lab, you will learn how to configure a continuous integration (CI) pipeline for a web application using Docker Cloud’s automated build features.

Docker Swarm Orchestration Beginner and Advanced

In this lab, you will play around with the container orchestration features of Docker. You will deploy a simple application to a single host and learn how that works. Then, you will configure Docker Swarm Mode, and learn to deploy the same simple application across multiple hosts. You will then see how to scale the application and move the workload across different hosts easily.

What to do about WannaCry if you’re infected or if you’re not

Today is likely to be painful for many organizations all over the world that took the weekend off and are returning to the work-week to find hundreds or thousands of computers on their networks encrypted by WannaCry ransomware, which surfaced Friday and has been propagating ever since.Estimates by law enforcement agency Europol estimated yesterday that more than 200,000 computers in 150 countries were infected, but with the worm continuing to spread to vulnerable Windows machines, that number will surely rise.For those whose machines have not been infected, here’s what you need to do right away: Apply the Microsoft patch that will thwart the attack. It’s available here. If you can’t do that because you haven’t tested whether the patch will affect your software build, disable Server Message Block 1 (SMB1) network file sharing. That’s where the flaw is that it attacks. Consider closing firewall port 139, 445 or both because these are the ports SMB uses. Longer term, to guard against similar future attacks you should:To read this article in full or to leave a comment, please click here

Samsung to detail new Tizen OS for smart home appliances, IoT devices

In the future, your Samsung vacuum cleaner, robot or washing machine will run on an OS called Tizen RT, slated to be introduced and detailed on Tuesday.The OS for smart devices and gadgets -- in other words, internet of things (IoT) devices -- will be introduced by Samsung at its Tizen Developers Conference, which will be held in San Francisco starting Tuesday.Samsung will share the architecture and future release schedule for Tizen RT at the conference. A number of sessions are being held on how to deploy and update the OS across devices.The real-time OS is a slimmed-down version of the mainstream Tizen OS, which is being used in Samsung TVs, smartphones, Gear smartwatches and other devices. Though it is an open-source OS, Samsung is its biggest backer.To read this article in full or to leave a comment, please click here

IDG Contributor Network: BackupAssist takes a step back in time with a SME backup tool

I live my life in two worlds. The most visible world, at least to this audience, involves spending lots of time in Silicon Valley and the U.S. generally and conversing with the technology illuminati—those who “get” technology, the cloud and what it can offer the world.In my other life, I live in a small (like, tiny) rural village in deepest, darkest New Zealand. I’m surrounded by fine folk, the so-called “salt of the earth” who make a living from the land, sheep, grapes and the rural sector generally. To these folks, technology is simply another tool to add to the arsenal of tools they have at their disposal.+ Also on Network World: Deep dive on AWS vs. Azure vs. Google cloud storage options + For these people, cloud isn’t always an already-adopted opportunity. Rather they use a variety of technology products and services. I have a friend who runs an agricultural service business whose operational software is a DOS-based solution. While this may have friends in the technology world rolling their eyes and shaking their heads, it is the reality of the “real world.” As an aside, I’ve said for the longest time that technology companies Continue reading

Is Serverless the New Visual Basic?

With Serverless hiring less experienced developers can work out better than hiring experienced cloud developers. That's an interesting point I haven't heard before and it was made by Paul Johnston, CTO of movivo, in The ServerlessCast #6 - Event-Driven Design Thinking.

The thought process goes something like this...

An experienced cloud developer will probably think procedurally, in terms of transactional systems, frameworks, and big fat containers that do lots of work. 

That's not how a Serverless developer needs to think. A Serverless developer needs to think in terms of small functions that do one thing linked together by events; and they need to grok asynchronous and distributed thinking.

So the idea is you don't need typical developer skills. Paul finds people with sysadmin skills have the right stuff. Someone with a sysadmin background is more likely than a framework developer to understand the distributed thinking that goes with building an entire system of events.

Paul also makes the point that once a system has built experienced developers will get bored because Serverless systems don't require the same amount of maintenance.

For example, they had good success hiring a person with two years of vo-tech on-the-job training because they didn't have Continue reading

It’s Up To Each Of Us: Why I WannaCry For Collaboration

WannaCry, or WannaCrypt, is one of the many names of the piece of ransomware that impacted the Internet last week, and will likely continue to make the rounds this week.

There are a number of takeaways and lessons to learn from the far-reaching attack that we witnessed. Let me tie those to voluntary cooperation and collaboration which together represent the foundation for the Internet’s development. The reason for making this connection is because they provide the way to get the global cyber threat under control. Not just to keep ourselves and our vital systems and services protected, but to reverse the erosion of trust in the Internet.

HPC to Deep Learning from an Asian Perspective

Big data, data science, machine learning, and now deep learning are all the rage and have tons of hype, for better—and in some ways, for worse. Advancements in AI such as language understanding, self-driving cars, automated claims, legal text processing, and even automated medical diagnostics are already here or will be here soon.

In Asia, several countries have made significant advancements and investments into AI, leveraging their historical work in HPC.

China now owns the top three positions in the Top500 with Sunway TaihuLight, Tianhe-2, and Tianhe, and while Tianhe-2 and Tianhe were designed for HPC style workloads, TaihuLight is …

Worth Reading: Enabling DNSSEC Validation

In July 2010, we saw an important Internet milestone: the Domain Name System (DNS) root zone was signed with DNSSEC, the DNS security extensions. DNS was designed without much thought given to security, but DNSSEC adds much-needed authentication and data integrity features. With DNSSEC, information in the DNS, including the root zone, can be cryptographically signed. DNS clients can validate the resulting signatures to have more trust that the data coming out of DNS is the same as what the owner put in and signed, and that the data hasn’t been modified in transit. —APNIC

Will Windows 10-on-ARM PCs support Mixed Reality headsets?

A Windows-on-ARM PC is getting closer to reality. Microsoft showed off a prototype mini-desktop with an ARM processor running Windows 10 at last week's Build conference, with the PC running applications like Office.The PC was shown in a video posted on the Channel 9 website. The presenters reinforced Microsoft's previous message saying that all x86 applications will work on Windows-on-ARM PCs.Microsoft has maintained that the experience on Windows 10-on-ARM PCs will be similar to x86 laptops, but many questions remain. One revolves around whether Windows 10-on-ARM PCs will support Windows Mixed Reality headsets.To read this article in full or to leave a comment, please click here

Dell-EMC updates HCI line to address changing market requirements

Last week Dell and EMC held its first joint customer event since the two tech giants merged. The not-so-originally named Dell-EMC World was a forum for the newly formed company to showcase how it can help its customers navigate the complex world of digital transformation.The final keynote of the event was by the always-entertaining and equally brilliant Chad Sakac, head of the Converged Platform group.

Reporters dox WannaCry ransomware kill switch guy

It is sickening when people prove “no good deed goes unpunished” to be true. I’m looking at you, British tabloids, because it was mean, stupid and very irresponsible to dox the guy who discovered the first WannaCry ransomware kill switch and thereby stopped thousands of old Windows machines from becoming infected.He goes by MalwareTech on Twitter and has an avatar of a cat wearing sunglasses. If he wanted to use his real name and picture, then he would have. Clearly, he values privacy and tries to maintain at least some degree of anonymity.Yet after being hailed as a hero for discovering a kill switch as WannaCry ransomware swept across globe, shady journalists doxed him. They dug into everything they could find online about MalwareTech, including trying to pry information from his friends.To read this article in full or to leave a comment, please click here

The Itanic finally sinks

Intel has released the final versions of its Itanium RISC processor, the Itanium 9700 series, which are virtually unchanged from the last generation and uses a 5-year-old architecture. There are no new features or capabilities, just the most minor of clock speed bumps. In a reflection of how old the designs are, they come in four- and eight-core design with hyperthreading for twice the number of threads. Xeons are now coming with up to 22 cores. Clock speeds are 1.7Ghz to 2.66Ghz and the thermal package is 170 watts. A 3.4Ghz Xeon E7 with 22 cores runs at 165 watts. These things aren’t even remotely competitive, and Intel didn’t really try to address it. The quad core Itanium CPUs get a 133MHz speed bump, while the dual cores get no speed changes. To read this article in full or to leave a comment, please click here

Few Secrets of Successful Learning: Focus, Small Chunks, and Sleep

One of my readers sent me a few questions about the leaf-and-spine fabric architectures webinar because (in his own words)

We have some projects 100% matching these contents and it would be really useful this extra feedback, not just from consultants and manufacturer.

When I explained the details he followed up with:

Now, I expect in one or two weeks to find some days to be able to follow this webinar in a profitable way, not just between phone calls and emails.

That’s not how it works.
