Abstract - YS910 is a technical document that verifies system administration tasks and operations on AlmaLinux 9/10. It is compatible with distributions compatible with RHEL (Red Hat Enterprise Linux). The document provides a concise command cheat sheet, explains efficient workflows, and documents setup procedures to ensure reproducibility. The purpose of this project is to reduce work time, improve operational efficiency, and streamline system deployment.
Abstract - YS0 is an Ansible-based playbook for building a working environment on distributions based on RHEL (Red Hat Enterprise Linux). The playbook includes installation of Ruby, various servers, and additional tools. By applying predefined playbooks, it eliminates errors and inconsistencies caused by manual configuration and enables the creation of an idempotent environment. It also adopts Infrastructure as Code, allowing infrastructure states to be managed as code, which enables version control and high reproducibility.
Keywords:
Ansible, Git, IaC(Infrastructure as Code)
Abstract - YS1 is a Ruby gem that performs fundamental information processing. It is a conceptual model with practical usability, designed to improve the efficiency and accuracy of data handling and information processing. It emphasizes reproducibility, ensuring the same state can be consistently recreated across environments. The implementation uses a simple structure built with classes and modules, and includes automated testing. It also leverages metaprogramming to enhance usability for end users.

Abstract - YS124 is a document that compiles Ruby code snippets along with their execution results in irb (Interactive Ruby). It functions as a practical cheat sheet designed to help users quickly understand how code behaves in practice. By presenting Ruby code examples together with their outputs, it deepens understanding and supports faster development. It serves as a reliable reference for Ruby operations and patterns.
Abstract - YS1XL is a collection of reusable VBA (Visual Basic for Applications) functions designed for Microsoft Excel. It provides standardized, ready-to-use components that eliminate the need to repeatedly write the same code. By leveraging these functions, routine tasks can be automated and workflows can be streamlined. It also improves consistency and maintainability, making Excel-based operations more efficient and reliable.
