  • 3 Ways to Create MySQL Database Table

    In the past year, I’ve been building skills in working with a computer instance- configuration, placing it within a network, working with Linux and the command line, but it’s only now that I’m building a really important piece for application architecture- building a database. In this post, I’m going to create a database table for…

  • Config RAID and Logical Volumes

    I’ve written a few posts as I learned how to create a logical drive, and touched upon RAID systems too- in this post, I’ll combine the two together. There are three main steps, in part I, with creating a logical drive: 1. Create hard drives that will become LVMs 2. create volume group(s) and 3.…

  • Expanding LVM

    In a previous post, I added a virtual hard drive, partitioned it, used that partitition as a Physical Volume > LVM Volume Group (DATA) > LVM Logical Volume (development). That was a 1GB logical volume out of a total 1.06GB hard drive. Now, to enjoy the benefits of a LVM partition and dynamically extend it…

  • SSH From Mac to Ubuntu VM

    I had an Ubuntu instance running on VirtualBox- now, how to SSH that to my Mac? Is it possible to bring that virtual-to-“real world” machine running on the same network? Very curious to find out.. First, I downloaded openssh-server: Next, enable and start the SSH service:

    AWS: Configuration for CLI

    There are a number of hoops to jump through steps to take in order to have access to a local CLI on your local production environment (read, my mac at home, with a coffee mug perched nearby): take a look here. First, to create IAM access and credentials. We need to get authorization, basically, through…

  • Routing: QoS

    As part of the networking class that I am studying, we did a deep dive into routing. The class allows for hands-on practice using a virtual machine sandbox (which I’ll be sharing screenshots here), but I have also been supporting that with studying pages 395-420, and 231-277 in the All-In-One Network+ study book by Mike…

  • RaspberryPi and Hardware Control

    This post is going to be somewhat rambling without a clear destination, as this is my initial foray into configuring the Rpi to interact with sensors and such, and thus will be filled with my pokings and proddings. Here we go! First, I have been using the book ‘Make: Linux for Makers’ by Aaron Newcomb,…

  • PKM: Adventures with Obsidian

    I stumbled across an interesting thread around keeping notes of things learned, such as configuration, machine installs, good sites, etc, and Obsidian was mentioned. I’ve been using Evernote on an occasional basis, but after reading the posts, I became interested in the concept of an overall Personal Knowledge Management system. I decided to explore the…
