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.

Devuan GNU+Linux features and specs

  • Systemd-Free
    Devuan does not use systemd as its init system, which appeals to users who prefer alternative init systems like sysvinit due to systemd's complexity and perceived centralized control.
  • Stability
    Devuan aims to provide a stable and consistent operating environment by forking from Debian without using systemd, suitable for users who value stability over the latest features.
  • Compatibility
    Devuan maintains a high level of compatibility with Debian, allowing users to access a wide range of software packages available in the Debian repositories, minus those requiring systemd.
  • Privacy and Control
    By avoiding systemd, some users feel they have greater control over their system's processes, enhancing privacy and reducing potential data collection.

Possible disadvantages of Devuan GNU+Linux

  • Limited Software Support
    Some modern software packages that depend on systemd may not be available or function optimally on Devuan, potentially limiting choices for users requiring such software.
  • Smaller Community
    As a relatively niche distribution compared to Debian, Devuan has a smaller community, which may result in less community support and fewer resources or tutorials.
  • Delayed Updates
    Updates on Devuan may lag behind other distributions, as it takes time to ensure compatibility without systemd, which might affect users seeking the latest software features or security fixes.
  • Complex Migration
    Users migrating from systemd-based systems may face complexities or a steeper learning curve as they adapt to different init systems used in Devuan.

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

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

  • "You Wouldn’t Steal a DIV": How I Built My Portfolio
    Then for the component library, I was really into coss ui. I stumbled upon it randomly one day and loved it so much. My Nathan's AI project already had a UI heavily inspired by cal.com: send button, message suggestions... So when I saw they had a shadcn/ui library with that kind of style, it was perfect for what I needed. - Source: dev.to / 6 months ago
  • 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 — 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 / 6 months ago

  • Store birth date in systemd for age verification
    Hello, as always: imho. (!) idk the exact procedure which will apply to enter the birth-date on such a system, but if other comments are correct: just enter what you want! There will be no real possibility to tie this to anything "legal" / to "enforce" any "official" check of lets say your passport or other governmental id. And if in my personal opinion (!) the pretty crazy guy behind the systemd-project tries to... - Source: Hacker News / 6 months ago
  • User and Admin Documentation?
    I'm a new user with first install. Are there any user guides / admin guides available? I'm not seeing much documentation available at devuan.org -- maybe my eyes glaze over(?). Source: over 3 years ago
  • I removed Gnome and snapd from Ubuntu and it turns out the system underneath is reasonably lightweight with 130M ram and 2.8G disk usage.
    If Canonical spin a variant without systemd, possibly choosing Devuan as the base, it'll be great. Possibly, less resource hungry. Source: over 4 years ago
  • Trisquel GNU/Linux
    Trisquel's FAQ says: > Why should I use Trisquel instead of one of the better-known distributions? > There are literally hundreds of GNU/Linux distributions designed to fill every conceivable niche. Only a handful of them are entirely free software; Trisquel is one such distribution. ... But I disagree. Trisquel is based on ubuntu, and uses systemd. Not just as some optional init system you can remove -... - Source: Hacker News / over 4 years ago
  • Move from Ubuntu?
    If you're experienced, look at Devuan Chimaera. BTW, I always felt Gnome is the most productive work environment with that UI. I think Cinnamon may come close. Source: almost 5 years ago
