> According to [2], the cost to reclaim CO2 from natural gas sources is approximately $90 per ton on the high end

I may be reading that wrong, but I'm pretty sure that refers to the CCS cost when you capture at use (e.g. in a power plant). You can't really use CCS when you're heating a house, so the right price to compare to would be direct air capture which is an order of magnitude more expensive IIUC.

It's buried in the article, but the 77% number seems to be based on resistance heating instead of heat pumps:

> the annual energy bill to operate a standard gas furnace/AC combination is about $633 a year. With a heat pump, she said, it would likely be $609 to $718 annually, depending on the heat pump technology chosen and its configuration.

The ingress controller is so I can have multiple public apps and configure them with Ingresses (definitely possible to do the overall setup with just cloudflared but I wanted to use built in ingress objects instead of a complicated cloudflared config).

I feel like Tailscale gets you pretty close to an “easy private cloud”, it’s just the “public” part that’s still a bit tricky.

Yeah this is basically what I was planning to do before I learned about cloudflared.

Yeah that’s what I would do if I was just hosting a blog, I already had the k8s lab set up for other reasons and wanted to get more use out of it.

I would say you don't really need Kubernetes for this sort of setup (I already was running all the K8s stuff which is why I went with it, but docker compose or even just running things in systemd without containers would work too).

I think the main thing is to have some sort of network isolation (like a separate VLAN or a server that blocks outbound traffic) between stuff that's exposed to the internet and stuff that's private on the network.

(Author here) I mostly worry about security for this. If you have nothing private on your network it's probably fine, but if you have, say, a NAS that isn't using proper authentication (pretty common), an os/nginx vulnerability could end up exposing stuff.

Of course there are much simpler ways to lock things down also :)

(Author here) I’m kind of cruel to my hardware lol (they’re all frankenservers hacked together with random parts from eBay). I’m not doing anything fancy to protect from dust and whatnot, but it’s pretty much always chilly in the garage (and I’m using low power parts) so heating hasn’t been an issue.

This was a project I implemented for fun to try to understand how Raft works (and also get more practice with Rust). The basic idea is that some state gets synchronized between 3 browser windows (currently hard-coded) over WebRTC. It's pretty fast if you're on the same machine (I've seen ~2000 writes/second on Chromium).

It's probably not useful for real applications in its current form, but I could potentially see some use cases in peer-to-peer browser applications.
