Introduction Deploying configure kubernetes persistent volumes on freebsd 12 on a FreeBSD 12 machine differs from Linux in several important ways: packages come from the FreeBSD Ports Collection or the binary pkg repository, services are registered in /etc/rc.conf via sysrc(8), and firewall rules are written in pf.conf(5) syntax. This tutorial stays entirely within the standard […]
Introduction Deploying install k3s kubernetes on freebsd 12 on a FreeBSD 12 machine differs from Linux in several important ways: packages come from the FreeBSD Ports Collection or the binary pkg repository, services are registered in /etc/rc.conf via sysrc(8), and firewall rules are written in pf.conf(5) syntax.

Introduction This guide explains how to Configure Jail Networking on FreeBSD 12 on FreeBSD 12. FreeBSD uses the pkg(8) binary package manager, rc.conf(5) for service startup configuration, and pf(4) as its primary packet filter. There is no SELinux or AppArmor — instead, FreeBSD provides the MAC (Mandatory Access Control) framework and Capsicum for fine-grained privilege […]
Introduction FreeBSD 12 is a UNIX-derived operating system renowned for its network stack performance, ZFS integration, and Jail isolation primitives. Setting up set up freebsd jails with iocage on freebsd 12 on FreeBSD 12 follows the rc.conf/service(8) paradigm rather than systemd, which means enabling a service and configuring its startup options are done differently from […]
Introduction How to Install Portainer on FreeBSD 12 is a core administration task for any FreeBSD 12 server operator. FreeBSD 12 ships with the 15.0-RELEASE kernel, ZFS as the default root filesystem, Capsicum capability sandboxing improvements, and an updated ports tree. Unlike Linux distributions, FreeBSD uses rc(8) for service management, pf for packet filtering, and […]
Learning how to use class inheritance in Python 3 is one of the most powerful and frequently used concepts in object-oriented programming at Progressive Robot — inheritance lets you create new classes (child/subclasses) that inherit attributes and methods from existing classes (parent/base classes), promoting code reuse, reducing repetition, following the DRY principle, improving maintainability, and building scalable, hierarchical models for real-world applications (from simple utilities to enterprise systems, web APIs, data pipelines, game engines, and AI architectures).
Understanding class and instance variables in Python 3 is one of the most important concepts in object-oriented programming at Progressive Robot — class variables are shared across all objects of a class (like global constants or counters), while instance variables are unique to each object (like name, age, balance), allowing you to model real-world entities with both shared and individual data. Mastering class and instance variables in Python 3 is essential for writing clean, maintainable, scalable code in automation, web APIs, data processing, game development, AI models, and enterprise systems.
Introduction FreeBSD 12 is a UNIX-derived operating system renowned for its network stack performance, ZFS integration, and Jail isolation primitives. Setting up set up a private docker registry on freebsd 12 on FreeBSD 12 follows the rc.conf/service(8) paradigm rather than systemd, which means enabling a service and configuring its startup options are done differently from […]
Learning how to construct classes and define objects in Python 3 is one of the most powerful and frequently used skills at Progressive Robot — object-oriented programming (OOP) lets you create reusable blueprints (classes) and concrete instances (objects) that model real-world entities, encapsulate data and behavior, enable code reuse, improve maintainability, and build scalable applications (from simple scripts to enterprise systems, web APIs, data pipelines, games, and AI models).
