  • I’m running mine on a ~$33/year VPS at GreenCloudVPS. It’s a small instance (just me) but it federates with all the major instances which means it still does a bunch of work (since it has to handle incoming posts and comments from federated servers). It’s a decently powerful VPS with an AMD EPYC Milan CPU, 10GB RAM, and 100GB NVMe storage.

    For a medium-sized instance, I imagine you could get pretty far with a single <$100/month dedicated server from Hetzner or a similar provider.


  • Some servers have ECC. If you get a cheap one (like a Hetzner auction server), it’s less likely to have ECC. ECC protects against bitflips, but it won’t help if the RAM is starting to die. ECC isn’t magic - it just has an extra 8 bits of parity data per 64 bits of data. It still uses the same type of RAM chips.





  • If you don’t mind a web UI, Netdata is great. It collects a bunch of metrics once per second and can retain them for a long period of time. The web UI is pretty good. Their Github readme links to some example servers so you can try it out first. Just click the link to use it without an account (that’s optional).

    It’s mainly designed for servers, but there’s no reason you couldn’t run it on a client system. They’re focusing a lot on AI/ML-based anomaly detection as well as their cloud offering at the moment, but you don’t have to use either and can just stick to the open-source agent.






  • why is a tower defense game listed under Automation?

    and two of the most popular automation programs are missing (n8n and Node-RED).

    who on earth needs customer live chat and a lot of business-scale website analytics, webshop systems and CRM and ERP in their homelab??

    Maybe not in a homelab, but plenty of people self-host these. I’m setting up customer live chat (Chatwoot) and invoicing and account (Bigcapital) for my wife for example. I self-host website analytics (Plausible) and bug tracking (used to be Sentry but it got too complex to host, so now I’m trying Bugsink and Glitchtip) for my personal sites/projects, too.





  • This is one of the reasons they’re reducing the validity - to try and convince people to automate the renewal process.

    That and there’s issues with the current revocation process (for incorrectly issued certificates, or certificates where the private key was leaked or stored insecurely), and the most effective way to reduce the risk is to reduce how long any one certificate can be valid for.

    A leaked key is far less useful if it’s only valid or 47 days from issuance, compared to three years. (note that the max duration was reduced from 3 years to 398 days earlier this year).

    From https://www.digicert.com/blog/tls-certificate-lifetimes-will-officially-reduce-to-47-days:

    In the ballot, Apple makes many arguments in favor of the moves, one of which is most worth calling out. They state that the CA/B Forum has been telling the world for years, by steadily shortening maximum lifetimes, that automation is essentially mandatory for effective certificate lifecycle management.

    The ballot argues that shorter lifetimes are necessary for many reasons, the most prominent being this: The information in certificates is becoming steadily less trustworthy over time, a problem that can only be mitigated by frequently revalidating the information.

    The ballot also argues that the revocation system using CRLs and OCSP is unreliable. Indeed, browsers often ignore these features. The ballot has a long section on the failings of the certificate revocation system. Shorter lifetimes mitigate the effects of using potentially revoked certificates. In 2023, CA/B Forum took this philosophy to another level by approving short-lived certificates, which expire within 7 days, and which do not require CRL or OCSP support.


  • Yes, this requirement comes from the CA/Browser Forum, which is a group consisting of all the major certificate authorities (like DigiCert, Comodo/Sectigo, Let’s Encrypt, GlobalSign, etc) plus all the major browser vendors (Mozilla, Google, and Apple). Changes go through a voting process.

    Google originally proposed 90 day validity, but Apple later proposed 47 days and they agreed to move forward with that proposal.
