Container Structure Tests: Unit Tests for Docker Images

Thu, 01/11/2018 - 08:00

Usage of containers in software applications is on the rise, and with their increasing usage in production comes a need for robust testing and validation. Containers provide great testing environments, but actually validating the structure of the containers themselves can be tricky. The Docker toolchain provides us with easy ways to interact with the container images themselves, but no real way of verifying their contents.

Exploring Node.js with Mark Hinkle, the Executive Director of the Node.js Foundation

Thu, 01/11/2018 - 07:56

Even though JavaScript has been around for more than 20 years, it’s becoming the first class citizen for developing enterprise applications. There is a huge developer community behind this technology.

As Go 2.0 Nears, AWS Launches Developer Preview of Go SDK 2.0

Thu, 01/11/2018 - 05:36

There's now a developer preview of an updated SDK for the Go programming language available on the Amazon Web Services Inc. (AWS) cloud.

Sometimes called Golang, Go is a Google-backed, open source programming language optimized for large-scale apps, such as performant Web apps that can run at tremendous scale. It's now at version 1.9 stable, but is being moved to version 2.0, a major upgrade whose release data has not yet been revealed.

What is the Future of Wi-Fi?

Thu, 01/11/2018 - 04:36

While speed and stability have improved significantly in Wi-Fi networks over the last decade, there are new innovations that will become available in 2018 and into 2019 that will make Wi-Fi faster and more available than ever before.

The Wi-Fi Alliance, which is a multi-stakeholder industry consortium that is all about promoting Wi-Fi is working on a number of programs to advance Wi-Fi in 2018 and beyond. One of those programs is called Wi-Fi Certified Home Design.

Meltdown and Spectre Linux Kernel Status

Wed, 01/10/2018 - 15:36

If your Linux systems are running a normal Linux distribution, go update your kernel. They should all have the updates in them already. And then keep updating them over the next few weeks, we are still working out lots of corner case bugs given that the testing involved here is complex given the huge variety of systems and workloads this affects. If your distro does not have kernel updates, then I strongly suggest changing distros right now.

Oath’s Top 5 Open Source Goals

Wed, 01/10/2018 - 08:00

As with many other companies, the open source program at Oath started informally with a group of diligent engineers and a few legal people. But the ad hoc group soon realized it needed a more formal program if it was going to be able to scale to address more issues and achieve specific business goals. With a formal program in place, they are poised to achieve its goals.

The top five of Oath’s numerous open source goals, according to Yehuda, are:

The Linux vs Meltdown and Spectre Battle Continues

Wed, 01/10/2018 - 06:56

So, where are we with fixing the problems? Work is continuing, but the latest update of the stable Linux kernel, 4.14.2, has the current patches. Some people may experience boot problems with this release, but 4.14.13 will be out in a few days.

Patches have also been added to the 4.4 and 4.9 stable kernel trees. But, as Greg Kroah-Hartman added, "This backport is very different from the mainline version that is in 4.14 and 4.15, there are different bugs happening." Still, he said, "Those are the minority at the moment, and should not stop you from upgrading."

Spectre and Meltdown Attacks Against Microprocessors

Wed, 01/10/2018 - 06:00

The security of pretty much every computer on the planet has just gotten a lot worse, and the only real solution -- which of course is not a solution -- is to throw them all away and buy new ones.

Four Tips for a More Secure Website

Wed, 01/10/2018 - 05:30

Security is a hot topic in web development with great reason. Every few months a major website is cracked and millions of user records are leaked. Many times the cause of a breach is from a simple vulnerability that has been overlooked. Here are a few tips to give you a quick overview of standard techniques for making your websites more secure. Note: I do not guarantee a secure website if you follow these suggestions, there are many facets to security that I don’t even touch in this article.

Prometheus vs. Heapster vs. Kubernetes Metrics APIs

Wed, 01/10/2018 - 04:30

In this blog post, I will try to explain the relation between PrometheusHeapster, as well as the Kubernetes metrics APIs and conclude with the recommended way how to autoscale workloads on Kubernetes.

This post assumes you have a basic understanding of Kubernetes and monitoring.

New-Age Networking Predictions for the New Year: Open Source

Wed, 01/10/2018 - 04:06

As software-defined networking (SDN), network functions virtualization (NFV) and other new-age networking initiatives mature, we'll be taking a look at what's in store for some of the most promising projects in the new year, now examining the open source movement.

Modern networking techniques such as SDN and NFV are closely tied to the open source phenomenon. As they've originated, evolved and matured, such approaches naturally have gravitated to open source, which itself is in the midst of a rising popularity trend.

We asked members of the 2018 O'Reilly Velocity Conference program committee for their take on the tools and trends that will change how you work. Below you’ll find the insights that I believe will have the greatest impact on the community in the year ahead.

Irresistible Appeal of Open Source

Tue, 01/09/2018 - 05:30

Telecom companies have always cooperated in development of standards. It’s essential for interoperability – otherwise each company’s customers would only be able to interact with its other customers. But there’s a difference between agreeing on standards and sharing software.

Quantum Computers Barely Exist—Here’s Why We’re Writing Languages for Them Anyway

Tue, 01/09/2018 - 04:36

Quantum computers are still extremely rudimentary, and largely remain intriguing playthings in a few advanced research labs. That hasn’t deterred people from developing new programming languages for them.

The most recent one comes from Microsoft, which has unveiled Q# (pronounced Q sharp) and some associated tools to help developers use it to create software. It joins a growing list of other high-level quantum programming languages such as QCL and Quipper.

But given that practically nobody has a quantum computer, what’s the point?

2018: The Year of Kubernetes and Interoperability

Tue, 01/09/2018 - 04:30

On its own, Kubernetes is a great story. What makes it even better is the soaring interoperability movement it’s fueling. An essential part of enabling interoperable cloud-native apps on Kubernetes is the Open Service Broker API. OSBAPI enables portability of cloud services across offerings and vendors.
