Wormhole.app features and specs

  • End-to-End Encryption
    Wormhole.app uses strong end-to-end encryption (E2EE), ensuring that only the intended recipient can access the files. This provides a high level of security and privacy.
  • Fast Transfers
    The app leverages modern technology to enable quick file transfers. Files start downloading for the recipient as soon as they begin uploading, reducing wait times.
  • Easy to Use
    Wormhole.app offers a simple and intuitive user interface, making it accessible even for non-technical users. The drag-and-drop functionality further simplifies the file-sharing process.
  • Temporary Storage
    Files shared via Wormhole.app are automatically deleted after 24 hours, which helps in conserving storage space and maintaining privacy.
  • Large File Support
    Wormhole.app supports the sharing of large files up to 10GB, catering to users who need to transfer sizable amounts of data.

Possible disadvantages of Wormhole.app

  • 24-Hour Expiry
    While temporary storage is a pro for some, the 24-hour expiry time can be a limitation for users who need longer availability for their shared files.
  • No User Accounts
    The lack of user accounts means there is no way to track past transfers or retrieve links once they are lost, which could be inconvenient for some users.
  • Internet Dependency
    Wormhole.app requires a stable internet connection for both uploading and downloading files, which could be a limitation in areas with poor connectivity.
  • Browser-Based
    As a browser-based application, Wormhole.app might not offer the same level of integration and features as a dedicated desktop or mobile app.
  • File Size Limits
    Although the 10GB limit is generous, it may still be a constraint for users needing to transfer even larger files, such as extensive video projects or full datasets.

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.

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

  • Show HN: PinSend – Share text between devices using a PIN(P2P, no login)
    This is very nice and simple. A few areas for improvement, in my opinion: the URL should be easy to copy, paste, or type into another device. I'd suggest designing the route like pindsend.app/pin/CODEHERE. Also, for some reason, copying and pasting the URL didn't seem to work in its current form. I would also consider implementing a QR code to allow quick scanning and redirection on another device, especially a... - Source: Hacker News / 1 day ago

    Then, I came across Cal.com, a fantastic open-source project for scheduling meetings and managing tasks (super useful for productivity!).

  • Fellow HSP entrepreneurs, how do you manage your energy and stress?
    I force clients who want to talk to me to book a call. I use cal.com (free) and my Google Calendar (which its linked to) only allows calls on specific days/times. I have a few "Call Blocks" where they can book. That let's me do calls in a small section of my week, with ample downtime to recover the rest of the week. I'm still learning how many calls a day I can handle. Currently anything more than 2 is too much. Source: over 1 year ago
