I Hacked Together a GlusterFS Calculator

Posted on
I’m doing some work to modernize my server infrastructure on Linode for all things FelicianoTech and Revidian. After not using this tech for several years, I’m ready to run a GlusterFS cluster again for shared storage. Some things have changed and making sure I understand “Dispersed Volumes” and what that would look like in terms of nodes, bricks, and storage space was heavy on my mind. I decided to make a quick calculator for Gluster Dispersed Volumes so I can play around with some numbers and see how they affect each other. continue reading →

Grepping Python Version Sometimes Fails

Posted on
Another quick one. I was recently trying to verify that the Python version I expect to be installed actually was while in a CI environment. The command python --version | grep "<version>" does the job…. most of the time. I found out that for some reason, Python 2 outputs the version info to stderr instead of stdout. This meant that my grep check would fail even when the Python version was correct. continue reading →

Forking pyenv Part 2: Creating a Baseline

Posted on

Whenever I start a significant amount of work on a codebase, I like to push up to GitHub a baseline branch. I’ve written about this before but to summarize, I like to get the lay of the land before I start creating changes. This allows me to build confidence in the CI process and makes debugging future problems easier.

With forking pyenv, I decided it would be smart to create a solid baseline here as well. Here’s what I did.

Starbucks WiFi Not Working? Using Tailscale?

Posted on

Here’s a really quick one I wanted to share. Today I rode to Starbucks to get a nice weekend work session in. I’m working on some fun stuff such as Pungi, Revidian Auto, etc. I logged in to my MacBook Pro, connected to “Starbucks WiFi”, and the WiFi login/redirect screen never popped up. This happens on occasion and there’s a few troubleshooting steps you can do to fix it. I won’t go over them here (let me know in the comments if you want me to) but I will go over how I fixed this weird Tailscale and captive portal issue.

Forking pyenv Part 1: A Learning Exercise

Posted on

pyenv is a very popular Python version manager that is maintained by people who are most certainly more knowledgable in Python than I am. So I decided I am going to fork the project all by myself. 😄 It may sound silly but I actually have some practical use cases that can come from this exploratory fork. I decided that I’ll document my journey with this project as I go. Let’s start with part 1, the “why”.

Import Public SSH Keys From GitHub

Posted on

Here’s a quick one.

Recently I needed to give one of my co-workers access to my personal Linux server. SSH felt like the easiest way to do that but I needed his public key. GitHub makes that easy.

Install Minecraft on Ubuntu

Posted on

I tried doing this today and ran into a small hitch. The official Minecraft website gives you a .deb file to install. No package manager or instructions. A couple blog posts I found had instructions that worked, but gave instructions which I felt were too long or installed unnecessary things.

Here’s how to install Minecraft Java Edition on Ubuntu, short and sweet.
