Possible disadvantages of s6

    Although there is documentation available, it may not be as comprehensive or accessible as that of more widely-used systems like systemd.
  • Steep Learning Curve
    Users accustomed to other init systems might find the learning curve steep when transitioning to s6, due to its unique approach and design.
  • Community Size
    The community around s6 is relatively small compared to more popular init systems, which might result in fewer community-driven resources.
  • Compatibility
    Not all third-party packages or distributions support s6 out of the box, potentially requiring additional effort for integration.

Possible disadvantages of fastThread

  • Limited Platform Support
    FastThread appears to be focused primarily on LinkedIn, which limits its usefulness for users who need content for multiple social media platforms.
  • Dependence on AI Quality
    Since content is AI-generated, the quality and originality of posts can vary, sometimes requiring manual editing to ensure it sounds authentic and matches the user's voice.
  • Potential for Generic Content
    AI-generated content can sometimes lack the nuanced personal touch or unique insights that a human writer might provide, leading to less differentiated posts.
  • Subscription Cost
    As a paid tool, ongoing subscription costs may be a barrier for individual users or small businesses with limited budgets.
  • Learning Curve for Optimization
    While the tool is easy to use, getting the best results often requires understanding how to craft effective prompts, which may take some time for new users to learn.

  • How to Run a Web Server on 27MB of RAM (and a Solar Panel)
    Drop cloudflared in favor of WireGuard (kernel module, negligible userspace cost) and you're comfortably under 27MB. Replace systemd with something like s6 or plain old SysVinit and you shave off another 2-3MB. - Source: dev.to / 3 months ago
  • Way too many ways to wait on a child process with a timeout
    Not so much about timeouts, but related in that it is based around managing children processes: The lineage of tools descending from daemontools for service management is worth exploring: daemontools: http://cr.yp.to/daemontools.html runit: https://smarden.org/runit/ s6: https://skarnet.org/software/s6/ dinit: https://davmac.org/projects/dinit/. - Source: Hacker News / over 1 year ago
  • Which do you use systemd or openrc? Why do you use what you use?

  • init software: What's the difference?
    Of the two I have experience with, runit is simpler and thus easier to get the hang of than s6-rc/s6. Though the s6 (not s6-rc) docs at the author's site contain a lot of info (including apologetics and rationales) that applies almost equally well to runit. Source: over 3 years ago
  • Trouble with s6 services
    Using the s6-service add command I added a service called "libvertd" when I ment to put "libvirtd". Now when I run s6-db-reload it spits out a error message saying "undefined service name libvertd". But I cant remove it using s6-service remove libvertd because that just spits out a generic help message and doesn't change anything. I also couldn't find documentation on Https://skarnet.org/software/s6/ or... Source: almost 4 years ago
