Tag Me In

Sun, 02 Apr 2023 12:00:00 -0500

In fall of 2020, I took time to collect myself and reflect on what I value using an exercise from Brené Brown in Dare to Lead. I also revisited what my Clifton Stregthsfinders 2.0 said about me. How can I focus my effort to be more effective and where would it be most impactful for others to “tag me in”? It’s been a few years, but this introspection feels especially relevant today.

Kubernetes: A Cautionary Tale

Sun, 05 May 2019 06:10:46 -0600

The gap between Minikube and Kubernetes in production is vast and full of pain. Want to know what it’s like to implement Kubernetes (k8s) in production for the first time before you collect the bumps and bruises yourself? Join me to learn about the ups and downs of one company’s initial experience with k8s - including who was involved, the scope, and what was intentionally deferred.

We will cover:

Why even consider Kubernetes (Hint: you might not benefit from it!)
How a real company approached their first proof-of-concept
How goals changed during implementation of k8s
What we learned so far
What we still need to learn

Hugo URL Aliases

Sun, 06 Jan 2019 15:13:10 -0600

When I built and posted some content on my site today using Hugo v0.53, I found that I had unintentionally broken some permanent links I was proud of. Thankfully, Hugo has a built-in feature - aliases - to address this issue.

My First Podcast

Fri, 23 Nov 2018 20:13:19 -0500

In October I was fortunate to be invited by Bryan Hogan to join him to talk about data science on the No Dogma Podcast. That episode posted in November. It was a really good time. :)

Kubernetes By Component - Part 5

Mon, 17 Sep 2018 17:33:21 -0500

As I prepared to present the four previous posts (part 1, part 2, part 3, part 4) as “Dissecting Kubernetes” at KCDC X, I tried to upgrade from v1.9 to v1.11 of Kubernetes and I found that when we only have the kubelet and the kube-apiserver we run into a permissions issue we didn’t have before.

Kubernetes By Component - Part 4

Mon, 10 Sep 2018 11:01:09 -0500

This is part 4 in a series of posts related to Kubernetes. Pervious posts were about kubelet, Kubernetes API, etcd, and kubectl, and kube-scheduler. This time we will explore kube-controller-manager and its role in managing replication of pods (a.k.a. scaling).

First Conference Presentation

Sun, 02 Sep 2018 21:24:10 -0500

In 2018 I gave my first conference presentation. It was quite the journey from being at NDC Minnesota in May — swearing I didn’t have the guts to be a speaker — to presenting at the Kansas City Developer Conference (KCDC) in July to a room of 120+ people.

Kubernetes By Component - Part 3

Thu, 22 Mar 2018 15:06:42 -0500

This is part 3 in a series of posts related to Kubernetes. Pervious posts were about kubelet and Kubernetes API, etcd, and kubectl. Like those posts, this one was is inspired by another 2015 post by Kamal Marhubi and is intended to update and expand on the topics with my own thoughts and learnings. Our focus will be exploring kube-scheduler.

Kubernetes By Component - Part 2

Sun, 25 Feb 2018 17:42:36 -0600

This is part 2 in a series of posts related to Kubernetes. Part 1 was about the kubelet. Like part 1, this post is inspired by another 2015 post by Kamal Marhubi and is intended to update and expand on the topics with my own thoughts and learnings. We will explore kube-apiserver, its relationship to etcd, and get a taste of why kubectl is so nice.

Syntax Higlighting Problems

Sun, 11 Feb 2018 15:11:48 -0600

The allure of nice syntax highlighting without leaving Markdown was one of the things that drew me to Hugo. In practice, I have found there are a number of challenges in implementation to get it to work as I expect. I was also reminded why I prefer not to spend my time fighting with CSS. ;)

Post Formatting

Thu, 08 Feb 2018 23:03:45 -0500

When I started looking into some of the finer points of how my Hugo site looked, I had a few post formatting questions:

Why does the sub-header look different in the post listing and page view?
Why do the date posted and tags not appear in the page view but do in the post listing?

What and Why of Kubernetes

Thu, 08 Feb 2018 16:45:56 -0600

As I have been exploring Kubernetes (k8s), I have run into a number of resources that I wish I had read in a different order. Below are my recommendations for getting started with Kubernetes.

Kubernetes By Component - Part 1

Thu, 01 Feb 2018 16:53:08 -0600

@kamalmarhubi published his “What even is a kubelet”, the first of three posts on Kubernetes (k8s), in summer of 2015 which introduced basic components of the container orchestration platform one at a time. This is my attempt to update and extend the topic with my own observations and include additional references I have found useful while trying to get my head around Kubernetes.

Pygments to Chroma Migration

Sat, 11 Nov 2017 23:59:24 -0600

As mentioned in my Pip Permissions post, when I upgraded past Hugo v0.28 I noticed that Chroma was now preferred over Pygments. Eventually, I tried tackling the migration.

Adventures in Tmux, Tmuxinator, and Powerline

Sat, 11 Nov 2017 20:46:03 -0600

After a few conversations with coworker, I found myself seeing possible uses for tmux in my workflows - in particular for working on Hugo. That led to thoughts of scripting tmux with tmuxinator and making it pretty with Powerline.

Summary Splitting in Hugo

Sat, 04 Nov 2017 23:46:06 -0500

When exploring why another implementation of the Beautiful Hugo theme had summaries that looked much nicer than what I was seeing on my own site, I found out how Content Summaries are determined.

The Hugo Index Page

Thu, 17 Aug 2017 19:15:43 -0500

In a previous post I talked about my experience setting up a Hugo site. Since then I have been exploring various additional Hugo-related threads including this one - configuring the main page (a.k.a. Hugo homepage).

Pip Permissions

Mon, 14 Aug 2017 20:40:08 -0500

In my first post I ran into some permisions issues related to Python and Pip.

My First Post

Sat, 05 Aug 2017 07:23:08 -0500

After a discussion with a passionate co-worker about the merits of various static site generation options and seeing an example of Hugo combined with what seemed like attractive code blocks, I decided to give it a try.
