Mastodon is a social media platform that has gained popularity as an alternative to Twitter. It is built on the principle of federation, which allows for independently operated servers, known as instances, to form a network. Each instance is run by an individual or group and has its own set of rules and moderation policies, providing users with the ability to find communities that align with their interests and values. I have been exploring Mastodon for a few years and found it to be a refreshing alternative to Twitter. In fact, I was so impressed with it that I decided to self-host my own instance.

While it may require more technical knowledge to maintain than the other software listed here, it is not excessively difficult to host an instance of Mastodon.

Key Features and Benefits of Mastodon:

  1. Decentralized structure: Mastodon’s decentralized nature offers numerous benefits, including increased user control, reduced reliance on a single entity, and enhanced resilience against censorship and server downtime. By distributing content across a network of instances, Mastodon empowers users and communities to define their digital experiences.
  2. Privacy and data ownership: Mastodon puts a strong emphasis on privacy and data ownership. User data is stored locally on the instance they choose, granting them greater control over their personal information. Moreover, Mastodon offers granular privacy settings, allowing users to customize the visibility of their posts and control who can interact with their content.
  3. Ad-free and non-commercial: Unlike mainstream social media platforms, Mastodon is ad-free and does not rely on monetizing user data. Funded primarily through donations and voluntary support, Mastodon offers a user experience free from targeted advertising, promoted content, and the pressures of commercial interests.
  4. Content moderation and user safety: Mastodon’s decentralized structure enables each instance to implement its own content moderation policies, allowing communities to define their guidelines and standards. This flexibility fosters diverse and inclusive online spaces while enabling users to find instances that align with their values and interests.
  5. Customizable and extensible: As an open-source platform, Mastodon encourages customization and extensibility. Users can develop and contribute to the platform, creating new features, themes, and integrations. This collaborative approach ensures that Mastodon continues to evolve and meet the changing needs of its user base.

Home Assistant

My journey into home automation began with just a handful of smart plugs, which gradually expanded. Initially, I was hesitant to adopt Home Assistant and used Zwave devices with Samsung SmartThings instead, later integrating them into Home Assistant. Eventually, I fully committed by acquiring a Zwave/Zigbee USB hub for Home Assistant, and now the majority of my home is connected to it in some way. I had anticipated more of a hassle than a convenience, but I was proven wrong. Setting up all your devices with Home Assistant may be time-consuming, depending on their connection requirements, but once that’s done, everything runs smoothly. Without Home Assistant, I would be manually controlling many of my devices, consuming more time. I must admit, it’s both an enjoyable hobby and an incredibly useful tool.

Key Features and Benefits of Home Assistant:

  1. Comprehensive device compatibility: Home Assistant offers compatibility with a vast array of devices and services, such as Zwave, Zigbee, Philips Hue, Nest, Google Assistant, and Amazon Alexa. This extensive support ensures that you can seamlessly integrate your existing smart devices and easily expand your home automation system as new technologies emerge.
  2. Privacy-focused and secure: As an open-source platform, Home Assistant emphasizes privacy and security. All data and information are stored locally on your system, ensuring that you have full control over your data. Furthermore, Home Assistant’s active community continually works to identify and address potential security risks.
  3. Customization and flexibility: Home Assistant’s open-source nature allows users to tailor the platform to their specific needs. With support for custom components, plugins, and a powerful automation engine, you can create a truly personalized smart home experience.
  4. Energy-saving potential: Home Assistant enables you to monitor and control your home’s energy consumption. By automating your lighting, heating, and cooling systems, you can optimize energy usage and reduce your environmental impact, ultimately saving money on your utility bills.
  5. Accessibility and convenience: With Home Assistant’s mobile app and web interface, you can monitor and control your home from anywhere. Whether you want to check your security cameras while on vacation or adjust your thermostat from your office, Home Assistant offers you the flexibility to manage your home on the go.


Upon initially exploring 3D printing, I quickly realized that I required more control over my printer. My Ender 3 V2 printer adequately meets my 3D printing demands, yet I found it lacking in terms of management and monitoring capabilities. This changed when I came across Octoprint, a versatile software that connects to various 3D printer models. Octoprint enables me to precisely control the printer and enhance its monitoring during operation. Additionally, numerous plugins can be incorporated to extend its functionality. The software is simple to install and currently runs on my Raspberry Pi.

Key Features and Benefits of Octoprint:

  1. Remote Monitoring and Control: Octoprint enables you to monitor and control your 3D printer from any device connected to your network. Whether you’re using a smartphone, tablet, or computer, you can access the printer’s status, initiate prints, pause, or cancel them at your convenience.
  2. Time-lapse Videos: Octoprint can automatically generate time-lapse videos of your prints, allowing you to observe and analyze the printing process in detail.
  3. G-code Viewer: Octoprint’s built-in G-code viewer provides a visual representation of your print, enabling you to inspect the print layers and detect potential issues before they occur.
  4. Plugin System: The Octoprint ecosystem is further enriched by a large number of plugins developed by the community. These plugins expand the software’s functionality, catering to a variety of user needs such as automatic bed leveling, filament management, and advanced slicing options.
  5. User-friendly Interface: Octoprint’s web-based interface is intuitive and easy to navigate, making it suitable for users with varying levels of experience.
  6. Multi-Platform Compatibility: Octoprint’s compatibility with multiple platforms ensures that users can access the software regardless of their preferred operating system.
