Ohio LinuxFest 2017

Fri, 05/26/2017 - 11:33

The Ohio LinuxFest is a grassroots conference for the GNU/Linux/Open Source Software/Free Software community that started in 2003 as a large inter-LUG (Linux User Group) meeting and has grown steadily since. It is a place for the community to gather and share information about Linux and Open Source Software.

Thin Client Market Embraces Raspberry Pi

Fri, 05/26/2017 - 09:00

Is the Raspberry Pi ready to take over the low-end thin client market? This week, NComputing unveiled the RX-HDX, its second Raspberry Pi based thin client. In addition, ViewSonic announced a software upgrade for the Pi-based SC-T25 thin client that it announced last year.

An Introduction to Linux's EXT4 Filesystem

Fri, 05/26/2017 - 07:00

In previous articles about Linux filesystems, I wrote an introduction to Linux filesystems and about some higher-level concepts such as everything is a file. I want to go into more detail about the specifics of the EXT filesystems, but first, let's answer the question, "What is a filesystem?" A filesystem is all of the following:

Hyperledger Sawtooth Graduates to Active Status

Fri, 05/26/2017 - 05:00

We’re happy to share that Hyperledger’s Technical Steering Committee (TSC) has granted the Hyperledger Sawtoothmaintainer’s request to advance the project’s status from Incubation to Active. Hyperledger Iroha also graduated today.

What to Expect (and Not Expect) from Linux Universal Packages

Fri, 05/26/2017 - 04:00

Traditionally, Linux has relied on two main package formats, .deb (Debian) and .rpm (Red Hat). Although structured differently, both .deb and .rpm packages consist of upstream software customized for a particular distribution, plus the scripts to install any dependencies — that is, required libraries, utilities, and other packages — not already installed on the system. This arrangement restricts the required hard drive space to a minimum, and both formats have served Linux well for almost two decades.

The Architect Elevator — Visiting the Upper Floors

Fri, 05/26/2017 - 04:00

Many large organizations see their IT engine separated by many floors from the executive penthouse, which also separates business and digital strategy from the vital work of carrying it out. The primary role of an architect is to ride the elevators between the penthouse and engine room, stopping wherever is needed to support these digital efforts: automating software manufacturing, minimizing up-front decision making, and influencing the organization alongside technology evolution.

Google Plans to Demonstrate the Supremacy of Quantum Computing

Thu, 05/25/2017 - 08:00

Quantum computers have long held the promise of performing certain calculations that are impossible—or at least, entirely impractical—for even the most powerful conventional computers to perform. Now, researchers at a Google laboratory in Goleta, Calif., may finally be on the cusp of proving it, using the same kinds of quantum bits, or qubits, that one day could make up large-scale quantum machines.

Google, IBM and Lyft Launch Istio, an Open-Source Platform for Managing and Securing Microservices

Thu, 05/25/2017 - 06:20

Microservices, that is, breaking larger applications into small parts that communicate over APIs, is increasingly becoming the architectural style of choice for many developers (especially when coupled with containers). Managing this fleet of services introduces its own set of challenges, though.

And now, a brief definition of the web

Thu, 05/25/2017 - 06:00

What exactly is the web? It seems like a stupid question because we all know the answer: the web is the thing Tim Berners-Lee invented in 1989. It's not the same thing as "the internet," which is what we use to access the web, apps, and streaming video. It's what we visit every day with our web browsers on our phones and laptops. Simple, right?

30 Best Practices for Software Development and Testing

Thu, 05/25/2017 - 05:00

Joining any new company—with an established culture and programming practices—can be a daunting experience. When I joined the Ansible team, I decided to write up the software engineering practices and principles I’ve learned over the years and to which I strive to work. This is a non-definitive, non-exhaustive list of principles that should be applied with wisdom and flexibility.

Best Practices for 2-Factor Authentication and Password Creation on Linux

Wed, 05/24/2017 - 10:00

As we mentioned in the previous article, web browsers present the largest and the most exposed attack surface on your Linux workstation. We’ve already discussed some best practices that Linux sysadmins can follow to reduce the impact of a compromised browser, such as upgrading to Wayland, using a different browser for work/high-security sites, and using Firejail to create a sandbox around Linux applications.

Make Sense of Edge Computing vs. Cloud Computing

Wed, 05/24/2017 - 09:00

Edge computing will not replace cloud computing, though the two approaches can complement each other.

The internet of things is real, and it’s a real part of the cloud. A key challenge is how you can get data processed from so many devices. Cisco Systems predicts that cloud traffic is likely to rise nearly fourfold by 2020, increasing 3.9 zettabytes (ZB) per year in 2015 (the latest full year for which data is available) to 14.1ZB per year by 2020.

DockerCon Hands-On Labs Now Online

Wed, 05/24/2017 - 07:30

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.

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.

First-Class Tests

Wed, 05/24/2017 - 06:00

So first, some definitions. Pardon me for my hubris, but there are so many different definitions of “unit test” and “system test” and “acceptance test” out there that it seems to me someone ought to provide a single authoritative definition. I don’t know if these definitions will stick; but I hope some set of definitions does in the near future.
