Setting up a Ruby Development environment in Vim

I love the simplicity of using Visual Studio Code for Ruby development, but my true love still lies with Neovim for development. The complexity of configuring Vim/Neovim has kept me away from the environment for some time, but now with the advent of coc.vim and solargraph, setting up a ruby development environment with the power of VS Code has become extremely simple. Pre-requisites A few things to note before we get started.

Setting up Vim for modern Puppet development.

There’s a lot of fanfare for text editors like Visual Studio Code and Atom for general development these days while those that utilize Vim, Neovim, and Emacs seem to be forgotten. Thankfully, and I can’t believe I’m saying this, Microsoft has created a new standard for making language plugins for IDEs and text editors. The Language Server Protocol standard has made it simple to create cross-platform and cross-editor language plugins, as long as the IDE or editor knows how to handle the Language Server.

Sometimes the Linux Gaming Community sucks….

I’m a huge fan of gaming and my preferred PC Operating System family is Linux, so naturally, I would love to see Linux based OSes continue to be supported long into the future of gaming. Unfortunately, there are several hurdles to Linux becoming mainstream for gaming and one of them, unfortunately is the Linux Community. The Problem The Linux community is an absolutely awesome community when taken as a whole. We try to be helpful to newcomers, do whatever we can to promote our platform in constructive and respectful ways, and even will “foot the bill” to get things working for our users if necessary.

Configuring Puppet Server (part 2)

Setting up r10k Last time, we walked through setting up Puppet Server and PuppetDB using Puppet. This time, we will be adding r10k to the mix. What is r10k? r10k is a tool created by Puppet, Inc to manage configuration environments and code deployments to the Puppet Master. It is extremely simple to initially setup and get working, but also a bit difficult to master. I won’t be going over the basic install and setup of r10k today, you can find that in the r10k documentation.

Configuring Puppet Server (part 1)

So, I was planning on doing a blog post on setting up Puppet Server and PuppetDB on separate servers, with r10k and Hiera. The blog got a bit too large, so I decided to split it up into a three-part blog series. I should probably note that this series is targeted towards users of Puppet Open Source and there is an expectation the readers are somewhat familiar with the Bash CLI and basic Linux Admin.
