  • Be careful with powering HDDs on and off. That is actually the operation that puts the most strain on them AFAIK. Sadly there is no good rule of thumb when it does more harm than good, but I would guess if you turn it on more than once a week, you are probably doing more harm than good compared to just letting in run. Many people even intentionally turn off sleep-mode in “green” drives so that they don’t shut down automatically.





  • Many things are very similar on Linux compared to Windows (e.g. Browsing, Steam). One big difference is that people prefer using package managers to install software (instead of downloading and installing it manually).

    This. Especially for drivers, always use the package manager of your distro and do not attempt to manually install Nvidia drivers you downloaded from their website.








  • You might have to sit through a slightly longer waiting time every now and then, but Anubis is not invoked on every connection and once your browser is found to be worthy you can surf as before.

    The bigger issue might be if that old hardware can’t run a modern up to date browser, because then it doesn’t work at all, which is the real down-side of Anubis.

    I tried it with the default settings of the Tor browser though and that worked ok surprisingly.




  • It does not stop them, but it does make it more expensive and slower for the attacker.

    This is a bit of a misconception of what Anubis does. It uses PoW to enforce a full browser environment, but the PoW is only used once a week or so (or when there is some suspicious things detected). The PoW is then used to autogenerate a kind of password to store in the browser cookies, and to generate this “password” you can’t use the simple servers that are used at scale to scrape (practically ddos) the open internet right now.

    The main problem is with complex websites like git forges that these AI scrapers hit all the computational expensive deep endpoints and practically force them to shut down from overloading the CPU.

    Since I was forced to implement Anubis for my Forgejo instance I also experimented with it on Lemmy. Right now the results show that while Lemmy isn’t as badly effected by this AI scraping, there is still quite a bit of it happening. After adding Anubis the overall traffic went down by about a third on our instance, and it prevents the regular traffic spikes we previously saw and had no real explanation for.

    But we also ran in some strange issues with it. Most likely it is caused by Anubis detecting mobile connections with switching IP addresses as possible scrapers (who are known to first access pages from a more complete server to get cookies and so on and then switch to a cheaper server on a different IP to do the actual scraping). But we are still figuring out how to replicate those issues, and they might have been fixed in the latest Anubis update we applied yesterday.



  • What you need to be aware off is that the LibreOffice based options run a full headless LibreOffice client on the server for each connecting user and stream the view as tiles to the webclients. If you mostly use low power devices to access your office files remotely this can be great as it offloads the processing to the server. But I think in most home server or VPS settings the server speed is the more limiting factor.

    OnlyOffice on the other hand runs entirely in your browser and thus puts little extra strain on the server.


  • GoToSocial is just another Fediverse software that works with multiple users like any other. The difference is really only that it is tuned more towards smaller instances and as a result is easier to set up and maintain. It also assumes most people will be using a mobile app with it anyways and thus the built in webclient is very bare bones. It does work fine with external webclients like Phanpy though.
