08-02-2020: Updated with how I setup UFW on my home server
I’ve been tinkering a bit with Digital Ocean (use my referral link to get $100 in Digital Ocean credit) and I’ve decided to move a small personal project from Heroku to a droplet running a small Kubernetes (k8s) cluster. I want to do this both to learn about setting up k8s (very useful since I work with it daily) and because Digital Ocean is cheaper than Heroku for my use-case.
This will be the first post in a series about setting up this single-node k8s cluster on a Digital Ocean droplet; check out the do-k8s-node tag to find the other posts in this series; I’ll also be adding links to the next post in the series as I write them.
This first post is about the firewall built into Ubuntu: ufw as well as why I want to move from Heroku to Digital Ocean.
ActiveRecord.dup and constantize

active-record ruby
I’m still unsure how I want to use this blog and wether I intend on creating a separate section for these short “TIL” posts or if I want to keep them here, but for today I’m combining two TILs into a longer post. I’m also using this to experiment with a post not having an image associated with it; we’ll see if that bugs me and I end up changing it or not.
This week I’ve learned a bit about the limitations ActiveRecord’s dup function as well as how constantize works.

gloomhaven rules levelling
After not playing Gloomhaven for a bit, my wife and I opened up the box to realize that she needed to retire her character and make a new one before we play the scenario. Easy enough we thought, we opened up the rule book to ensure we were doing it the right way and… Lo and behold we had forgotten about things that make a fairly large difference.

postgres rails ruby active-record
PostgreSQL offers a few comparison functions that are very useful if your table has columns that require exactly one entry. I ran into a situation recently that utilized the num_nonnulls function combined with a DB constraint to ensure that only one of a group of tables had data.
Dotfile Shenanigans

dotfiles shell bash zsh
Recently I watched this video from RubyConf 2018 about dotfiles and decided to customize my own setup across my various systems (a personal Macbook, a work Macbook and a personal Linux server). If you’re not familiar with the concept of dotfiles, I’d watch the first few minutes of that video before continuing to read.
