Local-first Obsidian stores your notes locally on your device, giving you full control over your data and enhancing privacy.
Markdown Support Obsidian uses Markdown, making it easy to format text and compatible with many other text editors and tools.
Bidirectional Linking You can create bidirectional links between notes, which helps in building a knowledge graph and navigating related information more easily.
Customizability Obsidian is highly customizable with community plugins, themes, and various settings to fit different workflows.
Graph View Provides a visual graph view of your notes and their connections, aiding in understanding relationships and discovering insights.
Offline Access Since the notes are stored locally, you can access and edit them without an internet connection.
Possible disadvantages
Learning Curve Obsidian can be complex and overwhelming for beginners due to its extensive features and customizable nature.
Sync Limitations While local-first is great for privacy, it requires additional steps or third-party solutions for syncing across devices.
No True Real-time Collaboration Obsidian lacks native real-time collaboration features, making it less suitable for collaborative work compared to cloud-based solutions.
Limited Mobile Features The mobile version of Obsidian, while functional, is not as robust as the desktop application, potentially hindering productivity on the go.
Dependence on Plugins Many advanced features require the use of third-party plugins, which could lead to compatibility issues and reliance on community support.
Performance on Large Vaults Performance might degrade with a very large number of notes or complex graphs, impacting usability.
Performance JRuby runs on the Java Virtual Machine (JVM), which allows it to leverage the JVM's performance optimizations like just-in-time compilation, potentially making it faster than traditional Ruby interpreters.
Java Integration JRuby allows seamless integration with Java libraries and frameworks, enabling developers to utilize the vast ecosystem of Java packages and tools alongside Ruby code.
Concurrency Thanks to the JVM's native threading capabilities, JRuby can offer better support for concurrent execution of code, potentially leading to improved performance in multi-threaded applications.
Mature Ecosystem JRuby inherits the mature tooling and extensive ecosystem from Java, including robust IDEs, debugging tools, and monitoring systems, which can enhance development and deployment processes.
Cross-Platform Running on the JVM allows JRuby to be inherently cross-platform, making it easier to deploy applications across different operating systems without requiring platform-specific adaptations.
Possible disadvantages
Startup Time JRuby can have a longer startup time due to the initialization overhead of the JVM, which can be a disadvantage for applications that require rapid startup and shutdown times.
Memory Usage Applications running on the JVM tend to have higher memory usage compared to native Ruby interpreters, which can be a concern for resource-constrained environments.
Compatibility Although JRuby aims for compatibility with CRuby, there can be differences or limitations, particularly with C extensions, which can restrict the usage of certain Ruby gems not written in pure Ruby.
Complexity Integrating JRuby into a Java ecosystem might add complexity, especially for teams not familiar with the JVM, Java build tools, or Java ecosystem practices.
Community Size JRuby, while popular, does not have as large a community as CRuby (the standard Ruby interpreter), which may result in fewer resources or smaller community-driven support avenues compared to CRuby.

Why this product is good
Obsidian.md is considered good by many users because it is a powerful knowledge management and note-taking application that leverages Markdown for document formatting. It allows for bi-directional linking between notes, which helps in creating a network of interconnected ideas, often described as a 'second brain.' Its ability to support plugins, themes, and robust graph visualization also adds to its appeal. Additionally, it stores notes locally, ensuring privacy and data ownership, while being cross-platform compatible across Windows, macOS, and Linux.

Writers and researchers who benefit from linking related ideas and maintaining detailed notes.
Tech-savvy users or developers who appreciate the local storage and open ecosystem for plugins and customization.
Overall verdict
JRuby is a mature, high-performance implementation of Ruby on the Java Virtual Machine that offers a compelling option for developers who need Ruby's expressiveness combined with the JVM's ecosystem, concurrency capabilities, and enterprise integration.
Why this product is good
Runs Ruby code on the JVM, giving access to Java libraries and the broad Java ecosystem
True multithreading without a Global Interpreter Lock, enabling better use of multi-core hardware
Strong performance for long-running applications thanks to JVM JIT compilation and mature garbage collection
Seamless interoperability that lets you call Java classes from Ruby and vice versa
Compatible with much of the standard Ruby language and many popular gems and frameworks like Rails
Backed by an active open-source community and a long, stable development history
Enables deployment on Java application servers and integration into existing Java/enterprise infrastructure
Recommended for
Teams that want to write Ruby but deploy on JVM-based enterprise infrastructure
Applications needing true parallelism and heavy concurrency across multiple cores
Developers who need to leverage existing Java libraries within Ruby projects
Long-running services that benefit from JVM performance and tooling
Organizations standardized on the JVM but wanting Ruby's developer productivity

Mine and yours first Obsidian plugin
The first time I downloaded Obsidian was about two years ago and I really liked the concept of storing everything locally in simple markdown files without unnecessary clutter.
