If it’s a low resistance path to ground, it’ll get very very toasty! If it’s a lousy ground though, then it won’t…but it also won’t consume any power, so it’s not an effective way of scrubbing off electricity.
A good ground (low resistance) is found in your household wiring (the ground and/or the neutral). Of you short to that…well…you can guess what will happen! (Let’s hope you have proper circuit breakers.)
Of course. Like I said, we know how to do it, but it’s still an engineering feat to get it done.
That is not how it works.
When you short something to ground, it’s everything in between that needs to dissipate the heat. Think about what “sending it to ground” means—it means you connect the hot to the ground. But with what do you connect the two? A wire? Sure, but you better hope that wire can dissipate all that power, because that’s what it’ll try to do.
You can’t just “dump power on the ground.” That’s not how it works.
This gets posted regularly on Lemmy, and while the economic take is tone-deaf at best, there’s a real issue with generating more power than you can use. You can’t just dump grid power — it needs to go somewhere. The grid needs to consume as much as it generates at all times or else bad things happen.
There are of course solutions, but that doesn’t mean it’s not an engineering challenge to implement.
Figuring out what to do with kilowatts is easy, but figuring out what to do with megawatts, at the drop of a hat, is substantially harder.
…and regular old murder for ReiserFS.
Not sure what it is about filesystem maintainers…
Cool, I recommend it!
I have my public facing reverse proxy point to my public services, and I also have it set up as a “roadwarrior” VPN to my home. So, I can connect my phone via WireGuard to my VPS, and a local DNS resolves my private services to the private IP addresses in my home network (so, I also run a reverse proxy on my server, for internal services).
I also have an off-site backup using this — just a raspberry pi and an HDD at family’s, that rsyncs+snapshots over the WireGuard network.
I’m sure I’m not following all the best practices here, but so far so good.
VPS with a public ip (which just takes all the fun out of selfhosting)
Why do you say this? My VPS only runs a reverse proxy and WireGuard, with all services hosted on my computers at home.
Remember that RAID and redundancy is not backup.
Try to 3-2-1, or something similar/better, if you can.
I am fairly sloppy here, and I am also very cheap. I have multiple copies in my home for important stuff (mainly Immich), the in use copy being on SSD and a few backups on spinning rust. I have a raspberry pi with an external HDD at family’s place, with a daily rsync+snapshot, for off site backups.
Of course, I’ve never had a catastrophic failure, so who knows how smooth that would be…
I switched to Technitium and I’ve been pretty happy. Seems very robust, and as a bonus was easy to use it to stop DNS leaks (each upstream has a static route through a different Mullvad VPN, and since they’re queried in parallel, a VPN connection can go down without losing any DNS…maybe this is how pihole would have handled it too though).
And of course, wildcards supported no problem.
Maybe take a look at Outline. (Not affiliated, but I host it for myself.)
I also host KitchenOwl, but mostly just as a grocery list.
Nice Dali-esque chair!
AWS was recently “having issues” due to the Iran situation — same thing I wonder?
I’ve been pleased with it. Family is very relaxed about projects like this, but yeah it’s low power draw. I don’t think I have anything special set up but the right thing to do for power would be to spin down drive when not in use, as power is dominated by the spinning rust.
Uptime is great. Only hiccups are that it can choke when compiling the ZFS kernel modules, triggered on kernel updates. It’s an rpi 3/1GB RAM (I keep failing at forcing dkms to use only 1 thread, which would probably fix these hiccups 🤷).
That said, it is managed by me, so sometimes errors go unnoticed. I had recent issues where I missed a week of rsync because I switched from pihole to technitium on my home server and forgot to point the remote rpi there. This would all have been fixed with proper cron email setup…I’m clearly not a professional :)
Not the same, but for my Immich backup I have a raspberry pi and an HDD with family (remote).
Backup is rsync, and a simple script to make ZFS snapshots (retaining X daily, Y weekly). Connected via “raw” WireGuard.
Setup works well, although it’s never been needed.
Does you school library lend out laptops for this sort of thing? Or, can you remote into a library/lab computer for this?
I would definitely opt for a dedicated machine, running the recommended OS, no VM, as others in this thread have said. It’s one thing if it’s for a homelab, but for coursework…not what I’d be comfortable with.
If Gentoo can be both Chad and Schizo, Slack should definitely be in the Chad category too.
I mean, it’s Torvalds’ distro of choice iirc, which should count for something.
Yeah, good point. The “app setup” is built into android and iOS as far as I can tell (generating matter credentials, etc.). Better than 3rd party IMHO but not ideal, and a nonstarter for a lot of folks. Hopefully HA will come out with their own onboarding process at some point.
Fair enough; I have a dedicated SSID which is VLAN’d off from the rest of my network with no Internet access. Only my HA server can talk to those devices.
Oh they absolutely do! My only point is that grid supply must equal grid demand. There are many ways to achieve this, as folks here have pointed out.
Throttling power generation (turning off/disconnecting PV from grid for example), and storage (chemical, heat, or hydro battery) are all established technologies, they just need to be implemented properly to avoid supply/demand mismatch.
