Providing quality software engineering content in the form of tutorials, applications, services, and commentary suited for developers.
In this article I discuss how to use the modern Debian based Advanced Package Tool known on the command line interface as apt. To aid the discussion I provide examples of running several of the common package management commands on an Ubuntu 18 LTS server with explanations of what each command is doing.
This is the first article of a series featuring a collection of useful tasks for administering PostgreSQL on the Linux operating systems Ubuntu 18 LTS as well as CentOS 7. PostgreSQL is a powerful and robust Object Relational Database which is freely available as open source software and widely popular. In this article I cover how to install and initialize the PostgreSQL database cluster. I also cover the key configuration files as well as their purpose.
This is the third article of a series featuring a collection of useful tasks for administering PostgreSQL on the Linux operating systems Ubuntu 18 LTS as well as CentOS 7. For those unfamiliar, PostgreSQL is a powerful and robust Object Relational Database which is freely available as open source software and widely popular. In this article I cover how to create user accounts and establish connections with these accounts.
In this fifth article demonstrates how to change the default data directory of a PostgreSQL database cluster running on the Linux Ubuntu 18 LTS and Centos 7 operating systems. This article shifts focus to improving the scalability, robustness and, performance made possible by moving the data directory to it's own area of the file system. Isolating the data directory also reduces file access contention with other OS activities and allows for easier resizing.
This article reviews common text manipulation utility programs available within the Linux operating system. The article is chock full of discussions paired with simple examples to demonstrate the usefulness of several text utility programs available to Linux users.
In this article I demonstrate how to provision Linux based EC2 Virtual Private Servers along with Elastic Block Storage (EBS) Volumes using Terraform. Then I complete the use case by demonstrating how to mount the EBS volume devices on Linux XFS filesystems.
