• Voyager 9 Linux Distro Is Based on Debian GNU/Linux 9 "Stretch" and Xfce 4.12

  The developer of the Voyager Linux distro was pleased to announce the release and immediate availability of Voyager 9, a Debian-based variant derived from the recently released Debian GNU/Linux 9 "Stretch" operating system. Voyager 9 enter development at the end of February when the first Beta milestone arrived as an experimental build for those wanted to help the developer fix any annoyances of bugs. It's built around the latest Xfce 4.12 desktop environment and runs on top of a long-term supported Linux 4.9 kernel used by Debian GNU/Linux 9 "Stretch".

Servers: Docker Hub, Internet Archive, DevOps...

• Building Images with Dockerfile and Docker Hub

  In this series previewing the self-paced Containers for Developers and Quality Assurance (LFS254) training course from The Linux Foundation, we’ve covered installing Docker, introduced Docker Machine, and some basic commands for performing Docker container and image operations. In the three sample videos below, we’ll take a look at Dockerfiles and Docker Hub. Docker can build an image by reading the build instructions from a file that’s generally referred to as Dockerfile. So, first, check your connectivity with the “dockerhost” and then create a folder called nginx. In that folder, we have created a file called dockerfile and in the dockerfile, we have used different instructions, like FROM, RUN, EXPOSE, and CMD.

• What can developers learn from being on call?

  We often talk about being on call as being a bad thing. For example, the night before I wrote this my phone woke me up in the middle of the night because something went wrong on a computer. That’s no fun! I was grumpy. In this post, though, we’re going to talk about what you can learn from being on call and how it can make you a better software engineer!. And to learn from being on call you don’t necessarily need to get woken up in the middle of the night. By “being on call”, here, I mean “being responsible for your code when it breaks”. It could mean waking up to issues that happened overnight and needing to fix them during your workday!

• Making the Internet Archive’s full text search faster.

  The Internet Archive is a nonprofit digital library based in San Francisco. It provides free public access to collections of digitized materials, including websites, books, documents, papers, newspapers, music, video and software. This article describes how we made the full-text organic search faster — without scaling horizontally — allowing our users to search in just a few seconds across our collection of 35 million documents containing books, magazine, newspapers, scientific papers, patents and much more.

• DevOps: More Than Automation

  Type “devops” into any job search site today and the overwhelming majority of results will be for some variation of “DevOps Engineer”. The skills required will centre on tools like Puppet/Chef/Ansible, AWS/Azure, scripting in Python/Perl/Bash/PowerShell etc. Essentially, they’ve taken a deployment automation engineer role, crossed out “deployment automation” and written “DevOps” in its place.

How Linux and makerspaces can strengthen our social fabric

In recent years, we've seen the rise of makerspaces, a new social invention where people with shared interests, especially in STEAM (science, technology, engineering, art, and math), gather to work on projects and share ideas. I was intrigued when I learned about a makerspace in my community, because I had never heard of such a concept before. I've since learned that makerspaces offer so much more than just a place to learn and build. A well-run makerspace also knits together a community and its social fabric—and, most importantly, invites in people who might otherwise be marginalized.
