  • Pacing and Difficulty
    Some users may find the difficulty of certain challenges to be either too high or too low, making it harder to find problems that are appropriately challenging for their skill level.
  • Limited Career Development Features
    The site focuses primarily on coding challenges and lacks extensive resources for job placement or career development compared to other platforms like HackerRank or LeetCode.
  • Less Comprehensive Tutorials
    While CheckIO provides educational missions, it may not be as comprehensive in tutorials and explanations compared to other dedicated learning platforms like Codecademy or Coursera.

GitHub features and specs

  • collaboration

Possible disadvantages of GitHub

  • cost
    While GitHub offers free plans, more advanced features and private repositories come at a cost, which might be a barrier for some individuals or small teams.
  • steep_learning_curve
    For newcomers, especially those unfamiliar with Git, the learning curve can be quite steep, making it challenging to utilize all of GitHub's features effectively.
  • privacy_concerns
    Given its expansive, open nature, users must be cautious with sensitive or proprietary information. Even with private repositories, there is a latent concern over data privacy and security.
  • interface_complexity
    The user interface, while powerful, can be overwhelming and complex for beginners or those not deeply familiar with version control concepts.
  • performance_issues
    Occasionally, GitHub may experience downtime or performance issues, which can disrupt workflow and prevent access to repositories temporarily.
  • limited_storage

  • I am stuck!
    Have you heard of CheckIO (https://checkio.org/)? They have a gameified "Mario world" of coding challenges that are smaller and come with more explanation, tests to guide you through edge cases and provide hints. The challenges start from total beginner and progress to more advanced. And best of all, after you solve a problem they show you what other people do. I highly recommend this for you.

  • I feel like I may not be smart enough to get into the cybersecurity space
    Cyber isn't gonna be a light switch, where you can flip it and be good. Don't be too hard on yourself. Start with some hands on stuff like https://tryhackme.com or checkio.org. You could look at certs like Security+ or CySA+ for some direction. It took me years to get into cybersecurity, and I still don't feel like I know anything. Source: almost 3 years ago
