Possible disadvantages of Cal.com

  • Learning Curve
    Although it is highly customizable, the plethora of options and features may result in a steeper learning curve for new users who are not familiar with such scheduling tools.
  • Limited Free Version
    The free version of Cal.com comes with limitations that may not be sufficient for growing businesses or advanced users who require more comprehensive features.
  • Dependency on Integrations
    Cal.com's effectiveness heavily depends on its integrations. Without these integrations, some users might find the tool less useful or incomplete, especially if their primary tools are not supported.
  • Support
    While open-source has many benefits, it may also mean that immediate, personalized support could be limited compared to fully commercial solutions. This might pose a challenge for users needing quick resolutions.
  • Performance
    As an open-source platform, the performance might vary depending on how it is hosted and managed. Suboptimal configurations could lead to slower performance or downtimes.

ale features and specs

  • Asynchronous Linting
    ALE performs linting and fixing asynchronously, which allows it to function without blocking the editor. This results in a smooth and responsive user experience, especially when working on large files.
  • Wide Language Support
    ALE supports a vast number of programming languages and linters, making it a versatile choice for developers working with multiple languages. This wide support is beneficial for polyglot developers.
  • Passive Mode
    ALE operates in passive mode, meaning it doesn't require you to run any manual commands to check for errors. It automatically shows warnings and errors in real-time as you type.
  • Editor Integration
    ALE integrates directly into Vim and Neovim, leveraging their ecosystem and providing a seamless user experience without needing to switch contexts or use external tools.
  • Configurable
    ALE is highly configurable, offering many options for customization. Users can tailor it to fit their specific needs, from enabling or disabling certain linters to customizing how error messages are displayed.

Possible disadvantages of ale

  • Complex Configuration
    The plethora of configuration options can be overwhelming for new users, making it potentially challenging to set up and maintain the desired configurations without a deep understanding of both ALE and Vim/Neovim.
  • Resource Usage
    Running multiple linters asynchronously can increase resource usage, which might affect performance, especially on older or less powerful systems.
  • Vim/Neovim Specific
    As ALE is designed to work specifically with Vim and Neovim, it is not suitable for developers who use other text editors, limiting its adoption for teams using diverse tools.
  • No Error Fixing UI
    ALE provides linting feedback but lacks an interactive interface for fixing errors directly within the editor, unlike some other linting tools that offer more integrated fixing support.
  • Dependency Management
    Setting up ALE often requires managing external dependencies such as language servers or linter binaries, which can be complex and require additional maintenance.

Acuity Scheduling alternatives for businesses outgrowing it
The honest read: if you're leaving Acuity because your business outgrew simple scheduling โ€” you need deposits, add-ons, multiple staff and locations, and ideally a booking site you own โ€” Opencals is built for exactly that transition, and pay-as-you-go means it costs nothing until you're earning.

I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

  • AI Almost Sold Me a Subscription I Didn't Need
    I keep coming back to what would have happened if I didn't have a strong technical understanding of how calendar technology works โ€” the difference between local and cloud calendars, what an ICS feed is, why enterprise auth blocks third-party integrations. If this was many years ago before I gained all this experience, I would have stopped at the first confident answer from my search tool, installed one of those... - Source: dev.to / 5 months ago

  • Tell HN: Vim Has Autocomplete
    Ctrl-X Ctrl-L is line based completion, see :help CTRL-X_CTRL-L for details. :help ins-completion gets the useful docs, Vim's own docs are very good and worth spending some time learning how to use, so you can learn Vim itself better. Another favorite of mine is 'gf' to open the filename under the cursor, very useful combined with ^X ^F.

  • LazyVim
    FWIW, I still use regular vim with ale [0] and it does everything I want. It formats files with Black and isort, shows ruff and pyright errors, supports jumping to definitions, and has variable information available on hover.
