The 4 Major Tenets of Kubernetes Security

Fri, 02/16/2018 - 08:00

In a previous article, we learned about the threats to a Kubernetes deployment that may result in a multitude of compromises and undesirable scenarios. With these threat models in mind, we can now explore Kubernetes security along four major tenets:

Enterprises identify 10 essential tools for DevOps

Fri, 02/16/2018 - 07:00

In rough order of their appearance in the DevOps pipeline, based on real-world user feedback, here are the most essential DevOps tools:In some of these 10 major categories, just one tool rules the roost, such as Docker for application containers and Jenkins for CI/CD. In others, DevOps practitioners view a handful of tools as interchangeable, depending on personal preferences and the IT environment's specific requirements.

The Open Source Initiative Got a Makeover

Fri, 02/16/2018 - 05:50

The Defense Department launched the website on Tuesday, a new, streamlined portal for its similarly named initiative, a collaborative approach to meeting the government’s open source policy.

The site features a suite of new tools, including checklists that links to offer guidance, and represents “an evolution of the project,” according to Ari Chivukula, policy wrangler for the Defense Digital Service.

GPUs on Google’s Kubernetes Engine Are Now Available in Open Beta

Thu, 02/15/2018 - 07:00

The Google Kubernetes Engine (previously known as the Google Container Engine and GKE) now allows all developers to attach Nvidia GPUs to their containers.

The CNCF Takes Steps Toward Serverless Computing

Thu, 02/15/2018 - 06:00

Even though the idea of ‘serverless’ has been around since 2006, it is a relatively new concept. It’s the next step in the ongoing revolution of IT infrastructure that goes back to the days when one server used to run one application.

Observability: The New Wave or Buzzword?

Thu, 02/15/2018 - 05:00

Monitoring tells you whether the system works. Observability lets you ask why it’s not working.

FOSS Project Spotlight: LinuxBoot

Thu, 02/15/2018 - 04:36

Linux as firmware.

The more things change, the more they stay the same. That may sound cliché, but it's still as true for the firmware that boots your operating system as it was in 2001 when Linux Journal first published Eric Biederman's "About LinuxBIOS". LinuxBoot is the latest incarnation of an idea that has persisted for around two decades now: use Linux as your bootstrap.

Fluid HPC: How Extreme-Scale Computing Should Respond to Meltdown and Spectre

Thu, 02/15/2018 - 04:00

The Meltdown and Spectre vulnerabilities are proving difficult to fix, and initial experiments suggest security patches will cause significant performance penalties to HPC applications. Even as these patches are rolled out to current HPC platforms, it might be helpful to explore how future HPC systems could be better insulated from CPU or operating system security flaws that could cause massive disruptions.

A Better Marketing Plan for Your Open Source Software Project

Wed, 02/14/2018 - 09:46

Open source software (OSS) marketing today is unique: it’s a process of co-creating and co-executing a marketing plan with an entire community—developers, end users and vendors. This makes it distinctly different than most traditional technology marketing efforts, which generally focuses on business decision-makers exclusively.

Five Noteworthy Open Source Projects

Wed, 02/14/2018 - 08:36

The open-source movement has gained momentum over the last few years. So much so that The Linux Foundation recently formed the LF Networking Fund (LFN) in an effort to place multiple open source networking projects under a single umbrella. These types of projects allow virtually anyone to make modifications, and potentially improve, software code through a process called upstreaming.

The Best Rising Linux Distros in 2018

Wed, 02/14/2018 - 06:06

Linux is built for tinkering and experimentation, which means it’s always morphing and changing. New distros are popping up all the time, because all it takes is a little bit of determination, time and effort to create a custom operating system.

Not all of them hit the mark – there are stacks of Linux distros that have seen little to no action, and we’re almost certain that some have been released and never installed by anyone other than their creator.

So let’s look at our pick of the five distros moving up swiftly through the ranks in 2018. 

The History of the Service Mesh

Wed, 02/14/2018 - 05:36

The idea of a service mesh is still a fairly new concept for most people, so it may seem a little funny to already be talking about its history. But at this point Linkerd has been running in production by companies around the world for over 18 months — an eternity in the cloud-native ecosystem — and we can trace its conceptual lineage back to developments that happened at web-scale companies in the early 2010’s. So there’s certainly a history to explore and understand.

Julia vs R vs Python: Simple Optimization

Wed, 02/14/2018 - 05:00

In this post, I will try to compare and contrast Julia, R, and Python via a simple maximum likelihood optimization problem which is motivated by a problem from the credit risk domain and is discussed in more detail in this post.


For such a simple optimization problem, R, Julia, and Python/SciPy will all do a competent job, so there is no clear winner. However as noted by Julia discourse member ChrisRackauckas
