321 strategy: 3 copies of everything important, 2 on-site, 1 in cloud. I have a TrueNAS Scale NAS running RAID5 on ZFS. All the laptops, desktops, etc. backup to the NAS. (Mostly Macs, so we use time machine over the network). So the original laptop/desktop is 1 copy. The NAS is a second copy on-site, and then TrueNAS has lots of cloud options. I use Amazon S3 myself, but there are lots of choices.
Prior to this I had a Synology NAS. It was "small" (6TB), so it has a RAID mirror of 6TB drives and a single 6TB external USB that had a backup of the mirrored pair (second copy on-site). Then I also used Synology's software to backup to S3.
For my Internet-facing VMs, they all run in xcp-ng and I use Xen Orchestra to manage them. I run regular snapshots nightly, and then use NFS to copy them to a cloud server. That's sloppy, and sometimes doesn't work. So the in-the-house stuff is backed up well. The VMs are mostly relying on Xen snapshots and RAID 5.

Thanks for the suggestion! I checked that webisite but to sign up it requires a donation and i’d rather use something else. I’m not looking for anything specific really, I just like to scroll down the list and see what interests me. I like math/physics/electronics/computers etc. Pretty much everything related to computer engineering (I need it for college)
It’s basically because they don’t directly convert electricity into heat, they just pull it in from outside. It still takes energy to ‘push the heat uphill’ from a cold place to a hot place, but less than directly heating.
To take my previous comment to the next level, have you ever put your finger over the end of an old-school bicycle pump and tried to push it in? If you have, you’ll know that the pump gets hot. The reason is that you are not only compressing air, you are compressing the heat that the air has. This raises the temperature and we can use this phenomenon to move heat around.
Imagine you were outside where it was cool and you extended the bicycle pump and blocked the end permanently.
Then you went inside hour house and compressed the pump. The air (and heat) in the pump would be compressed into a smaller space, so it the air temperature of the air in the pump would increase. If you compressed it a bit, the air in the pump might go up to be the same temperature as the air inside your house. If you compressed it even more, it would get hotter than the air inside the house. If you then held it there, over time, the heat inside the pump would transfer through the wall of the pump to the air in your house. This would cause the air inside your house to warm up and the air inside the pump to cool down until they are the same temperature. In doing this you have taken the heat in the air outside, and released it inside.
If you then went back outside and allowed the pump to extend again, then the air would decompress and, because the heat previously left the air in the pump (when it was inside), it would get quite cold. Colder than the air outside. If you then waited again, the air in the pump would gradually warm up, drawing heat from the air from outside of your house. This happens because even though the air outside is cool, it’s still warmer than the air in the pump.
Rinse and repeat. An air conditioner on heating mode, or a heat pump basically work in the same way. However, rather than using a bicycle pump, they have fluid running in a loop from inside to outside and back inside. The evaporator (outside the house) collects heat by allowing the fluid to ‘expand’ and cool below the ambient temperature outside. The condensor (inside the house) releases the heat by allowing the fluid to ‘contract’ and heat above the ambient temperature inside.
In this way, no heat is directly created from electricity. It is just moved from outside to inside. Believe it or not, this takes less energy than converting electricity into heat directly.
I’ve deliberately not talked about phase change here to keep it simple, that doesn’t change the basic idea behind it.
Did you try the docker-compose file referenced in these instructions? It worked first try for me. The hardest part was proxying externally. I’m used to using SWAG so I had to get the nginx config working with SWAG.
I consider reading a cultivating activity to enrich one’s knowledge on certain topics. This is why I, like you, find myself reading predominantly nonfiction.
Fiction, however, can be utilized to disclose valuable information as much as to offer leisure. One novel I have in mind is The Elegance of the Hedgehog by Muriel Barbery, which quite explicitly tackles philosophical and social questions via the protagonists’ journal entries.
Agreed. Sometimes fiction reflects reality very well, in its own unique way. I used to be a journalist, and I recall some of my colleagues wondering whether they could do more good by moving to fiction and taking on larger issues in that medium.
PULSAR is pretty amazing if you have a few friends to play with. It really feels like actually running a spaceship together. You can shout things like “Divert all power to main turrets” and actually mean that.
Pulsar is the game that I feel like was so close to being a great game but they gave up on it before it got there. Working together to run the ship is awesome but the world is SOOO empty. Like at least add mod support so folks can help or something. I want to love the game but that always stops me.
I’m too early in the game to know this well, but I feel the lack of mod support. This feels like a game that would really thrive with community support, but they have no plans on supporting mods or open sourcing it. They are currently working on a new project that they haven’t elaborated on yet.
Still, I got this game for $14 and if I can find some people to play with I’m absolutely going to get my money’s worth - this kind of game just doesn’t exist with this level of depth. I love the technical detail of how the ship works on and how the systems interact with each other.
I’m currently hitting an issue of lets encrypt failing to authenticate using the .well-known. The domain in the hosts file is lemmy.domain.com though I have a feeling this may have to be the FQDN. the base domain is currently being used by matrix to serve antoher .well-known so it looks like I’ll have to add another page there somewhere.
yes, the domain in the hosts file needs to be the fqdn. Let’s encrypt will look for the auth file at the root of that. if you are already using this fqdn/webroot you’ll need another cname.
I don’t think I’m using the root for anything, just domain.com/.well-known/matrix/server. Would I be able to serve the challenge at domain.com/.well-known/acme-challenge/stringofcharacters?
I think so. letsencrypt will only be looking for the file that certbot creates, so as long as it can resolve the fqdn to your host and port 80 (yourdoma.in) is navigable, then you should be good.
certbot certonly --manual is what I need though I think cloudflare or something else is making it only resolve to https. I’m going to shelf this for now and come back to it later. Thanks for your help
