Depends on Load. Realistically, one of the used “Mini PC’s” from Lenovo or HP with an i5 and integrated graphics should be decent for a couple of concurrent streams. They are pretty cheap on ebay. You could even get 3 or 4 and cluster them in some form. But most SBCs won’t work too well since transcoding needs a decent GPU of some sort.

Second this. I downsized from a couple of heavyweight enterprise servers to a handful of USFF Dell Optiplexes for the bulk of my self-hosted applications. I also have a stack of upgraded thin clients that run my smaller apps wonderfully.
The power, heat, and noise reduction has been amazing.
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.
All subdomains on apache proxies… its a bit of a mess though. Whenever it comes to update something I can never remember how I installed it. Theres a heady mix of script installs, deb installs, source installs. I’ve got Gitea ready to update but I have no idea what method I used to install it :')
I just read the post about backups. Since we don’t need 100% uptime. It is so easy to shut down the services, tar.gz the data folder, then store the in b2, restart everything and your server is looking schmick again!

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 believe it’s in the public interest to reopen both the skon-scown and the roll-bap-cob debates. Civil war to put in place the rules we plan to follow going forward, what!
I remember when I was a kid we moved from Newcastle to Scotland and I swear it took my Mum years to get used to saying rolls instead of buns. I wonder how many iced buns she had to go through before getting it right.
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.
If you have the full community name (like this place is [email protected]) it should come through on search, though it might take a while. Especially if it’s a community on a heavily loaded server like lemmy.ml, you may want to try a couple of times, waiting a minute or two in between, so the search gets a chance to resolve.
It’s lemmy.world/c/gunners I am signed up to the feddit.uk server, I don’t understand why UKcasual on the same server works but that one doesn’t.
I can view it on browser but the jarboa app can’t seem to find it, and I can’t seem to log in on the lemmy.world site to subscribe because it won’t recognise my details from feddit.uk.
