Possible disadvantages of KnowCSS

  • Limited Depth of Content
    KnowCSS may not cover advanced CSS topics in sufficient depth, which means experienced developers may find the resource too basic for their needs and would need to supplement with other resources.
  • Limited Community and Support
    Compared to larger platforms like MDN Web Docs or CSS-Tricks, KnowCSS has a smaller community, meaning fewer discussions, forums, or peer support for troubleshooting issues.
  • Narrow Scope
    The site focuses specifically on CSS, so users looking for a comprehensive web development learning platform covering HTML, JavaScript, and other technologies will need to use additional resources.
  • Less Frequently Updated
    Smaller niche tools like KnowCSS may not be updated as frequently as major documentation sites, potentially missing coverage of the latest CSS features and specifications.
  • Limited Real-World Project Examples
    The platform may lack complex, real-world project examples that demonstrate how CSS properties work together in practical scenarios, which can leave a gap between learning individual properties and applying them in production.

  • Ask HN: What do you monitor on your servers?
    Https://hetrixtools.com/ It's free if you don't have too many servers - 15 uptime monitors (the most useful) and 32 blacklist monitors (useful for e-mail, but don't know why you'd need so many compared to uptime). It's fairly easy to reach the free limits with not many servers if you're also monitoring VMs, but I've found it reliable so far. It's nice you can have ping tests from different locations. - Source: Hacker News / almost 2 years ago
  • How to check how many resources use my website?
    You can use "htop" command to view current CPU, RAM and SWAP usage, also see which process is taking up how much of each resource. And if you want to collect data over time, you can use a monitoring agent like https://hetrixtools.com/ to monitor network, cpu, ram, disk access etc all of the time. Source: about 3 years ago
  • Does ManageWP have a feature to monitor SSL Uptime?
    HetrixTools about the best free service I've used that includes that. Source: over 3 years ago
  • Is hetzner down?
    You can use hetrixtools Uptime Monitor for free. Https://hetrixtools.com Better Uptime is also good. Https://betterstack.com/better-uptime. Source: over 3 years ago
  • Xfinity is what the folks are using?
    I'm using Ziply and they have been pretty much rock solid. I have a free uptime service via https://hetrixtools.com/ and they claim that in 2022 my uptime percentage is 99.9990%. And likely some of that is when I have decided to reboot my router. Source: almost 4 years ago
