Technology Short Take #75

Welcome to Technology Short Take #75, the final Technology Short Take for 2016. Fortunately, it’s not the final Technology Short Take ever, as I’ll be back in 2017 with more content. Until then, here’s some data center-related articles and links for your enjoyment.

Looking Back: 2016 Project Report Card

As I’ve done for the last few years, in early 2016 I published a list of my planned personal projects for the year. In this post, I’d like to look back on that list of projects and grade myself on my progress (or lack of progress, if that is the case). Even though 2016 isn’t over yet, it’s close enough to the end of the year that things won’t change that much before 2017 is upon us.

Opening Web Internet Location Files on Ubuntu

As part of my effort to make myself and my workflows more “cross-platform friendly,” I’ve been revisiting certain aspects of how I do things. One of the things I’m reviewing is how I capture—and later review—posts or articles on the web. On OS X, I would run an AppleScript that generated a .webloc file (aka an Internet location file). This is an XML file that OS X understands. However, Linux doesn’t natively understand these files, so today I came up with a solution to reading .webloc files with Ubuntu and Firefox.

The Linux Migration: Initial Progress Report

About 4 years ago, I discussed some changes in the Apple ecosystem that might lead me to move away from OS X. To be honest, I’ve made only token efforts since that time to actually migrate away, even though the forces that I described in that post are still in full effect. In fact, some might say that the “iOS-ification” of OS X (now rebranded as “macOS”) is even stronger now. As a result, I’ve stepped up my work on a Linux migration, and I’m happy to report that I’ve made some progress.

Hiding the User List on the Ubuntu Login Screen

In this post, I’m going to share how to hide the user list on the login screen for Ubuntu 16.04. The information here isn’t necessarily new or ground-breaking; however, in searching for the solution myself I found a lot of conflicting information as to how this may or may not be accomplished. I’m publishing this post in the hopes of providing a bit more clarity around this topic.

Installing Ansible 2.2 on Ubuntu 16.04

A few weeks ago I wrote a post about installing Ansible 2.2 on Fedora 25; today, I’d like to tackle what’s involved in installing Ansible 2.2 on Ubuntu 16.04. This post, like its Fedora counterpart, stems from my ongoing evaluation of Linux distributions and desktop environments. While the information here is very similar to the information in the Fedora post, I’m putting it in its own post in the hopes of making the information easier for readers to find.

Using OVN with KVM and Libvirt

In this post, I’m going to discuss how to use OVN (Open Virtual Network; part of the Open vSwitch project) with KVM and Libvirt to provide virtual networking for KVM-based virtual machines. This post will build on some concepts around OVS and Libvirt that I’ve discussed previously; be sure to review the OVS posts and Libvirt posts on this site for more details and prerequisite knowledge.

Technology Short Take #74

Welcome to Technology Short Take #74! The end of 2016 is nearly upon us, and it looks as if there will be only one more Technology Short Take before the end of the year. So, let’s get on with the content—time is short!

Learning Environments for OVN

Over the last few days, I’ve added two new Vagrant-based learning environments to my GitHub “learning-tools” repository, both of them focused on Open Virtual Network (OVN). OVN, if you aren’t aware, is part of the Open vSwitch (OVS) project aimed at adding open source network virtualization functionality to OVS. If you’re interested in learning more about OVN, you may want to check out these new learning environments.

AWS re:Invent 2016 Keynote with Werner Vogels

This is a liveblog of the Thursday keynote at AWS re:Invent 2016. Today’s keynote is led by Werner Vogels, CTO of Amazon Web Services. Unlike yesterday, today I opted not to attend the keynote in the main hall, viewing the keynote instead from an “overflow” area. Turns out the “overflow” area has drinks, tables, and power! That’s a far better option that being crammed in the main hall, though in the past I’ve found it more difficult to liveblog when not viewing the keynote directly. We’ll see if that continues to hold true.
