Obsidian.md 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.
  • 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 of Obsidian.md

  • 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.

Apache Cassandra features and specs

  • Scalability
    Apache Cassandra is designed for linear scalability and can handle large volumes of data across many commodity servers without a single point of failure.
  • High Availability
    Cassandra ensures high availability by replicating data across multiple nodes. Even if some nodes fail, the system remains operational.
  • Performance
    It provides fast writes and reads by using a peer-to-peer architecture, making it highly suitable for applications requiring quick data access.
  • Flexible Data Model
    Cassandra supports a flexible schema, allowing users to add new columns to a table at any time, making it adaptable for various use cases.
  • Geographical Distribution
    Data can be distributed across multiple data centers, ensuring low-latency access for geographically distributed users.
  • No Single Point of Failure
    Its decentralized nature ensures there is no single point of failure, which enhances resilience and fault-tolerance.

Possible disadvantages of Apache Cassandra

  • Complexity
    Managing and configuring Cassandra can be complex, requiring specialized knowledge and skills for optimal performance.
  • Eventual Consistency
    Cassandra follows an eventual consistency model, meaning that there might be a delay before all nodes have the latest data, which may not be suitable for all use cases.
  • Write-heavy Operations
    Although Cassandra handles writes efficiently, write-heavy workloads can lead to compaction issues and increased read latency.
  • Limited Query Capabilities
    Cassandra's query capabilities are relatively limited compared to traditional RDBMS, lacking support for complex joins and aggregations.
  • Maintenance Overhead
    Regular maintenance tasks such as node repair and compaction are necessary to ensure optimal performance, adding to the administrative overhead.
  • Tooling and Ecosystem
    While the ecosystem for Cassandra is growing, it is still not as extensive or mature as those for some other database technologies.

Obsidian.md 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.
