RVM VS DiffDojo

• Ruby Version Management
  RVM allows users to easily install, manage, and work with multiple Ruby environments and versions on a single machine.
• Gemset Management
  It provides the ability to create and manage gemsets, which helps in isolating gems and their dependencies for different projects.
• Project Isolation
  RVM ensures that each project can have its specific Ruby version and gemset, reducing conflicts between dependencies of different projects.
• Convenience and Ease of Use
  The tool is user-friendly and simplifies tasks like upgrading Ruby versions or switching between them without complex configurations.
• Community Support
  Being widely used, RVM has strong community support, which means abundant resources for troubleshooting and learning.

Possible disadvantages

• Environment Overhead
  RVM installs binaries and libraries within the user’s home directory, which can lead to increased usage of disk space.
• Performance Impact
  Switching between Ruby versions or gemsets may introduce performance delays as environments are activated.
• Complexity with System Ruby
  There can be complexities and potential conflicts when using RVM alongside the system's default Ruby installation.
• Dependency on Bash
  RVM heavily relies on Bash, which may not be ideal for users who prefer or require different shell environments.
• Learning Curve for Beginners
  New users to Ruby programming might experience a learning curve in understanding how to effectively use RVM.

• Focused Learning Tool
  Based on the name suggesting a 'dojo' for diffs, it likely provides a specialized, focused environment for practicing and understanding code differences, which can be valuable for developers looking to sharpen specific skills like code review or version control comprehension.
• Practical Skill Building
  Tools with a 'dojo' branding typically emphasize hands-on practice, which can help users build practical, applicable skills through repetition and real-world scenarios rather than just theoretical knowledge.
• Niche Specialization
  By focusing specifically on diffs, the platform may offer deeper, more targeted training in this particular area compared to general coding platforms that cover many topics superficially.
• Potential for Gamification
  Dojo-style platforms often incorporate gamification elements like levels, challenges, or achievements, which can make learning more engaging and motivating for users.
• Community Learning Environment
  Such specialized platforms may foster a community of like-minded developers focused on the same skill set, potentially leading to peer learning and shared resources.

• Setting up Ruby on Rails with RVM, Puma, Mina, Nginx, Sidekiq and Redis on Amazon Linux 2

  Ruby (Installed using RVM, but you can use any other version manager, or compile yourself ruby). - Source: dev.to / almost 2 years ago

• Fixing A Broken Deployment to Google App Engine

  I checked build logs and found that bundle install was not working the same as it did on my machine. I installed rvm, tried multiple versions of ruby, attempted to upgrade various gems. Nothing worked. - Source: dev.to / about 2 years ago

• Problems starting msfdb init

  One suggestion would be to setup your install based on a development environment using git and a Ruby version manager like rvm or rbenv to allows you to setup a user controlled gemset and execution path. Source: about 3 years ago
