Possible disadvantages of LeetCode

  • Paid Subscription
    While LeetCode offers many resources for free, a premium subscription is required to access some advanced features, company-specific questions, additional test cases, and certain problem solutions.
  • Steep Learning Curve
    For beginners, the wide range of problem difficulties and the complexity of some problems can be intimidating and may require a significant amount of time and effort to get up to speed.
  • Limited Technology Coverage
    LeetCode mainly focuses on algorithm and data structure problems and doesn't cover other technical aspects like system design, databases, or front-end development as comprehensively.
  • Variable Quality of Community Solutions
    While the community is active, the quality of user-contributed solutions and explanations can vary significantly, and some may not follow best practices or be optimal.
  • Platform Performance Issues
    Some users report occasional performance issues such as slow loading times or glitches during peak usage times, which can be frustrating during practice or contests.
  • Overemphasis on Coding
    LeetCode's focus is predominantly on coding problems, which might lead some users to neglect other important skills required for technical interviews, such as communication and problem-solving in real-world scenarios.

Lem features and specs

  • Extensible and Customizable
    Lem is designed with extensibility in mind, allowing users to customize and extend its functionality to fit their specific needs, including creating custom commands and keybindings.
  • Cross-platform Support

  • Common Lisp Integration
    Lem is implemented in Common Lisp, and is particularly advantageous for users who are working within the Lisp programming ecosystem, providing a seamless development experience.

Possible disadvantages of Lem

  • Steep Learning Curve
    The editor may have a steep learning curve for users unfamiliar with Common Lisp or those new to more complex and highly customizable text editors.
  • Limited Community Support
    Lem has a smaller user base compared to more established editors, which might result in less community support, fewer plugins, and less frequent updates.
  • Dependency on Lisp Environment
    Lem's reliance on a Common Lisp environment could be cumbersome for users not already utilizing Lisp or who require additional setup time to configure their environment.

Lem mentions (28)

  • Emacs Is a Lispboard
    Something like Lem[1][2] could go even further because of the richer CommonLisp ecosystem compared to Elisp one. [1] https://lem-project.github.io/ [2] https://github.com/lem-project/lem. - Source: Hacker News / 2 days ago
  • My I3-Emacs Integration
    Sounds like you want Lem. Though it's common lisp instead of guile. https://github.com/lem-project/lem. - Source: Hacker News / 2 months ago
  • Editing Code in Emacs
    Thanks for sharing. I've been off editor hopping for quite some time, nowadays I just use some pre-defined configuration like Doom Emacs, occasionally I try to build some environment, with AI help, from "scratch" for fun and curiosity. I really like Emacs' flexibility + evil-mode and reactivity, recently I searched for something similar and found Lem: https://github.com/lem-project/lem, looks promising, I'll try... - Source: Hacker News / 8 months ago
  • IDEmacs: A Visual Studio Code clone for Emacs
    I don't agree with everything in their approach, but Lem (https://github.com/lem-project/lem) is a modern editor that has the Emacs Nature. - Source: Hacker News / 8 months ago
  • IDEmacs: A Visual Studio Code clone for Emacs
    It's not exactly what you're looking for but you might be interested in Lem[0]. It's an emacs-style editor but written completely in Common Lisp on top of curses/SDL2. I haven't used it that much (same for Emacs itself, really), but it looks like a very solid foundation [0]: https://github.com/lem-project/lem. - Source: Hacker News / 8 months ago
