Spousetivities at OpenStack Summit in Austin

Long-time readers know that my wife, Crystal, has been running this thing called Spousetivities for a few (OK, eight) years now. While Spousetivities originally started out as a VMworld thing, it rapidly expanded, and this year Spousetivities will be at a number of events. That includes the spring OpenStack Summit in Austin, TX!

Adding Git and Docker Machine Awareness to OS X

In this post I’m going to share how to add some Git and Docker Machine “awareness” to your OS X Bash prompt. This isn’t anything new; these tricks are things that Bash users have been employing for years, especially on Linux. For most OS X users, though, I think these are tricks/tools that aren’t particularly well-known so I wanted to share them here.

Docker Swarm on AWS using Docker Machine

In this post I’m going to talk about how to use Docker Machine to build a Docker Swarm cluster on Amazon Web Services (AWS). This post is an adaptation of this Docker documentation post that shows how to build a Swarm cluster using VirtualBox.

Learning Tools Updates

One of the projects that I started last year was my GitHub “learning-tools” repository, in which I store tools (of various sorts) to help with learning new technologies. Many of these tools are Vagrant environments, but some are sample templates for other tools like Terraform. I recently made some updates to a couple of the tools in this repo, so I wanted to briefly update my readers.

Using Docker Machine with AWS

As part of a broader effort (see the post on my 2016 projects) to leverage public cloud resources more than I have in the past, some Docker Engine-related testing I’ve been conducting recently has been done using AWS EC2 instances instead of VMs in my home lab. Along the way, I’ve found Docker Machine to be quite a handy tool, and in this post I’ll share how to use Docker Machine with AWS.

Vagrant, Ubuntu "Wily Werewolf," and Networking

In what has been a fairly classic “yak shaving” exercise, I’ve been working on getting Ubuntu 15.10 “Wily Werewolf” running with Vagrant so that I can perform some testing with some other technologies that need a Linux kernel version of at least 4.2 (which comes with Ubuntu 15.10 by default). Along the way, I ran smack into a problem with Ubuntu 15.10’s networking configuration when used with Vagrant, and in this post I’m going to explain what’s happening here and provide a workaround.

Technology Short Take #63

Welcome to Technology Short Take #63. I’ve managed to (mostly) get back to my Friday publishing schedule, though I’m running much later in the day this time around than usual. I’ll try to correct that for the next one. In any case, here’s another collection of links and articles from around the Net on the major data center technology areas. Have fun reading!

On the Topic of Lock-In

While talking with customers over the past couple of weeks during a multi-country/multi-continent trip, one phrase that kept coming up is “lock-in”, as in “we’re trying to avoid lock-in” or “this approach doesn’t have any lock-in”. While I’m not a huge fan of memes, this phrase always brings to mind The Princess Bride, Vizzini’s use of the word “inconceivable,” and Inigo Montoya’s famous response. C’mon, you know you want to say it: “You keep using that word. I do not think it means what you think it means.” I feel the same way about lock-in, and here’s why.

Technology Short Take #62

Welcome to Technology Short Take #62. Sorry for the long delay since the last TST; some global travel has really thrown my schedule off. In any case, I didn’t want to wait until Friday (the day I normally publish these) so I’m putting this out there sooner. Enjoy!

Full Stack Journey Episode #3: Jonathan Frappier

In Episode #3 of the Full Stack Journey podcast, I have the pleasure of speaking with none other than Jonathan Frappier. Jonathan blogs at VirtXpert, and is probably quite well-known for his role in wrangling speakers for the vBrownBag podcasts. Jonathan is @jfrappier on Twitter, and uses the same username on GitHub as well. Jonathan’s been in the IT industry for, as he puts it, “somewhere between 16 and 20 years.” Today, Jonathan and I talk about PowerCLI and leveraging the rest of your team at work to help with your success in making the journey to being a full-stack engineer.
