    Doesn’t meet your power requirements (only up to 850VA) but i recommend Cyberpower Bric meets the rest. I have mine connected to my Proxmox host, usb passthrough to VM running HassOS with the NUT add-on. Neat little LCD and silent unless humming on battery. Can choose if you want an audible alarm enabled or put it on mute.

    APC is still very well regarded UPS brand for small business, and your specs seems like they should be achievable across many leading brands. Have you looked into latest models for your spec?

    Maybe share a list of candidates you’re considering and can get opinions on those?

    Maybe for context could you share any reference article or graph which triggered this question? Increased in relation to what, since when?

    Not in the US, but from materials read before, it is a combination of things.

    Typical causes of weight gain in an individual is simply more calorie intake than is being burnt off. Across a population you can consider environmental, lifestyle and social factors which may contribute to this.

    1. Higher calorie intake (super-sized portions, highly processed foods with high sugar and fat content, cheap convenient fast foods and drinks, expensive healthy/nutritional foods, growth hormones in meats?).

    2. Less exercise (infrastructure not built for cycling and pedestrians, less manual labour jobs, Netflix, Home delivery services, etc).

    Health education, Food Advertising/Sponsorship, Chain loyalty discounts, Low wages (poverty), and Political influences would all play a part.


  • Agree. Best to have that dedicated hardware, and a degree in network engineering first! Hah :)

    tech waffle...

    You might achieve network isolation without dedicated managed switches by: using prosumer routers or OpenWRT, with a Hypervisor like Proxmox, which support VLAN tagging. But this wouldn’t save your home connection from a DDoS. To help with that, running public services behind CloudFlare seems to be one of the better choices, even our Lemmy hosts are using.

    If you’re starting out, best keep internet facing home services private through a VPN, maybe ZeroTier or TailScale. Don’t advertise them publically at all.


  • Agree with the VPS in this case. For sure you can create public-facing services in a home server or home lab, but to do so you need:

    1. Domain name hosting.
    2. an Internet Service Provider who will allow you expose port 80/443 web services and on a Static IP (most do not, or paid extra on business plans). OR use a Cloud proxy like CloudFlare which your home IP can be updated through a DynDNS service and served on private ports.
    3. Setup NAT/Port Forwarding on your modem to route incoming requests to internal services. First to a firewall or threat gateway like PFSense, a web proxy like Traefik/NGinX, and security harden and maintain your modem, router, network and served applications.

    If you’re new to these things, Id start with something more mature for personal or family home use first. Like NextCloud, HomeAssistant or Jellyfin media server. Lots of YouTubers have covered how these can be set up as a reference.

    Lemmy is still alpha, full of bugs and security vulnerabilities and needs regular hotfixes and babysitting. Permitting Joe Public into your home services is ripe for disaster unless you have the time and expertise.





  • Difficult to read the graph, but looks like you have less than 4GB ram. Depending what sort of OS and services are running (from above suggestions), this is likely the biggest issue.

    You haven’t mentioned which services you’re running, but 4GB might be enough perhaps for a basic OS with NAS file share services. But anything heavier, like running Container services will eat that up. You’d want at least 8GB.

    Note also that you may not have a dedicated graphics card? If you have integrated graphics, some ram is taken from System and shared with the GPU. If you’re just running command line, you might eke out a little more RAM for system by reducing the VRAM allocation in your BIOS. See: https://en.m.wikipedia.org/wiki/Shared_graphics_memory
