Action Packed Functions

Sep 9, 2019

Last month, GitHub announced new improved CI/CD with GitHub Actions. Since then, I have experimented with the new Action workflows and created an Action that wraps the faas-cli so that you can easily build and deploy your functions directly from GitHub. My initial interactions with the new GitHub Actions were not great, they really meant it when they said “public beta”. BUT!!! Having said that, there is clearly a lot of promise in GitHub Actions.

Developing OpenFaaS KinD-ly

Apr 4, 2019

There are several ways to run small Kubernetes clusters: k3s and k3d, minikube, and microk8s to name a few. Currently, my favorite is the Kubernetes provided by Docker Desktop for Mac. But this doesn’t help my friends (or myself) when I am on a Linux laptop. It would be nice to have one lightweight and shared environment for Kubernetes. Luckily, one of the Kubernetes groups has released KinD - Kubernetes in Docker.

When sequential tests aren't

Feb 2, 2019

At work we have been expanding the testing coverage of our auth service and have discovered the perfect storm of edge cases around test caching and Go’s test building. In short, we had tests that looked like they were passing locally but would fail sporadically in CI because Go will run the tests inside of a package sequentially but build and test each package in parallel (up to the number of CPU cores).

Golang long-polling: a tale of server timeouts

Jul 7, 2018

I recently had a week long battle implementing HTTP long-polling. As so often happens in long debugging session in software development, my final fix was one line!

Struct embedding for custom dev responses

Jan 1, 2018

I had to learn about Go struct embedding the other day and I wanted to document my fix. In my use case I wanted to add some extra information to an API response to include some meta data from kubernetes cluster and/or some extra error information.

Deploying a private registry in Docker Swarm

Oct 10, 2017

At Contiamo I am currently working a project that will eventually integrate with OpenFaaS. I am really excited about this project because we will soon bring some serverless magic to data scientists that use Contiamo. That is, once I figure out how to deploy a private Docker registry inside a Docker Swarm.

Berlin and Golang

Aug 8, 2017

At the beginning of the month I left Teem I was Director of Engineering and it was and still is a great company. There are some amazing developers there, so if you are looking for a job in SLC, hit them up. This weekend (Aug 5) I will be moving to Berlin to start a new role at Contiamo and will be working on the Labs feature.

Home Brewers Association Ruthless Rye Clone

Jul 7, 2017

This recipe is inspired by the Seirra Nevada Ruthless Rye Clone written up by the Home Brewers Association. I have adjusted it to be a partial mash recipe with about 8 lbs of grains.

I just finished my first official “summer beer” of the year, an Orange Honey Wheat. This one was inspire by my wife while at the store “you should do this one, it uses Utah honey!”, thank you tech lady ninja.

SSL Expiry Quick and Simple

Jun 6, 2017

Ever have that feeling you are forgetting something right as you leave work? You are probably thinking about your keys or your lunch box but I am talking about your SSL certificate. They don’t last forever, we know this when we setup SSL but that doesn’t stop it from sneaking up on us. It has happened to the big guys like Instagram and Google, at Teem recently, and of course for myself with my own home server.
