    LeetCode regularly hosts coding contests and challenges, which provide users with opportunities to compete against others and improve their skills under time constraints.

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.

Obsidian features and specs

  • 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.

Possible disadvantages of Obsidian

  • 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.

Obsidian Reviews

  1. The kind of software that may change your life

    Perhaps you know someone who swears by Obsidian, it may seem like a cult of overly devoted people for how passionate they are, but it's not without reason

    I've been using Obsidian for over 3 years, at a point in my life when I felt I had to handle too much information and I felt like grasping water not being able to remember everything I wanted, language learning, programming, accounting, university, daily tasks. A friend recommended it to me next to Notion (of which he is a passionate cultist priest) and I reluctantly picked it and fell in love almost immediately.

    Obsidian seems very simple, like a notepad with folder interface, similar to Sublime Text, but the ability to link files together in a Wiki style allows you to organize ideas in any way you want, one file may lead to a dozen or more ideas that are related

    If you want to do something specific, Obsidian has a plethora of community created plugins that expand the functionality, in my case, I use obsidian to organize my classes both as a teacher and as a student, using local databases, calendars, dictionaries, slides, vector graphic drawings, excel-like tables, Anki connection, podcasts, and more

    Competitors: Notion, Evernote
    Pros:    Awesome community|Custom plugins|Local hosting|Beautiful themes|Highly customizable|Cloud storage|Becomes more useful over time|Markdown support
    Cons:    Seems complicated/complex at first|Takes time to set up your personal workspace|Overwhelming for first time user

    My personal knowledge-base of choice

    I've been using Obsidian for more than a year. It's been great. I think it offer a great balance of control, flexibility and extensibility. What is more, you own your own data, that's been a must-have feature for me. I just can't imagine putting all my knowledge into something that I don't have control over.

    I think two of the most popular alternatives that people consider are Logseq and Roam Research. Although Logseq is a bit different, it's considered compatible with Obsidian. Supposedly, you can use them with a shared database (files. Both use simple text files for storage). I tried that once, a few months ago. It worked, yet it messed up a bit my Obsidian files ¯_(ツ)_/¯.

The 6 best note-taking apps in 2024
One thing to note: Notion bills itself as an Evernote competitor for personal users. It can be—but it's too much for most people, and its offline functionality isn't the best.

  • Which Markdown editor to choose
    Inline preview, usually called WYSIWYG. Obsidian's Live Preview mode hides the syntax except where the cursor is.
