Thanks! Luckily it has been pretty quiet since the bot issues and security issues. At this point it’s occasionally checking for Lemmy and server updates, and keeping an eye on server storage. One of the recent Lemmy updates fixes the database storage ballooning though so it will probably be a while before storage is an issue.
Split beam torque wrenches are where it’s at, especially for home use where it’s going to sit for long periods of time. Split beam is easier to set, and you don’t have to leave it at 0 when not in use. I have ruined many traditional clickers because I forgot to set it back to 0 for storage, then it sits like that for months.
They aren’t as cheap as a traditional clicker, but they are so much better.
Some satellites and rovers have used Radioisotope Thermoelectric Generators (RTGs), which are very different from a nuclear reactor. They use polonium-210, which generates heat, and that heat is converted to electricity with thermocouples. They are low power and inefficient.
To my knowledge no satellite, with an RTG, has ever used ion propulsion. Few interplanetary satellites have ever even used ion thrusters. Dawn, Hayabusa, and Deep Space 1 are the only I can think of, and they all used solar arrays.
Ion thrusters are super efficient, but produce extremely small amounts of thrust. They aren’t practical for getting large spacecraft to Mars. These proposed nuclear engines produce large thrust while have efficiency somewhere between regular chemical propulsion and ion propulsion.
For large instances pictures is probably the bigger consumer of space, but for small instances the database size is the bigger issue because of federation. Also, mass storage for media is cheap, fast storage for databases is not. With my host I can get 1TB of object storage for $5 a month. Attached NVMe storage is $1 per month per 10 GB.
For my small instance the database is almost 4x as large as pictrs, and growing fast.
If you have open registration you should reduce the account creation rate.
Ah, I understand now. At least 1 person on this instance has to be subscribed to the community on another instance for it to federate and show up here. All the communities that show up in “All” on this instance are ones that have been subscribed to by at least 1 user on this instance. It is one of the downsides of federation on a small instance, you don’t have a very good “All” to see popular content form communities you aren’t subscribed to.
There are some tools out there that will force federation with all communities, but the problem with that is it blows up storage requirements.
There may be some instances that manually defederated during the whole bot situation. I know there was a tool someone made that automatically updates the defederated list, but I already verified we were off that naughty list. So, it would only be instances that manually defederated that we may still be blocked on. In that case we’d have to message the instance owners and ask to be removed from the list.
I’m not sure I’m seeing any less communities though, could just be general federation issues. Any specific instances/communities you think are missing?
It runs /e/OS, which is very much a privacy focussed OS.
Sure, depends on what you want to do, that’s just the command I used to purge unverified accounts. My instance doesn’t really have any users so not a big deal.
Yeah, unless you are deleting hundreds of users you can’t really tell, but I deleted 6k+ bots and can confirm user count automatically updates.
Don’t delete from the local_user table. You only need to delete from the person table, the rest of the tables will be updated automatically and user count will update automatically.
Edit: The below command will delete all unverified users. NOTE: If you do not have email verification turned on then all users are unverified, therefore all users will be deleted. It also appears with v18 when you enable email verification all existing users remain unverified.
This is a destructive command, use at your own risk and don’t go fucking with the database if you don’t have backups.
DELETE FROM person WHERE local = 'true' AND id IN (SELECT person_id FROM local_user WHERE email_verified = 'false');
In the parenthesis you can add your AND to only select unverified accounts of a certain age.
Yes, person table is top level. Delete from person table and it cascades down and deletes from other tables. User count also automatically updates. Just be careful because person table also contains federated users. There is a “local” column to determine if they are local users or not.
I had about 6k bot accounts, but they were all unverified, so I just deleted all local unverified accounts from the person table.
Just don’t go messing with the database without backups. My host supports snapshots so I did a quick snapshot before messing with anything.
I still think instances should be largely region based, which is why I started one for Colorado. As far as sharing it I’m not really sure either other than spamming it everywhere (which I also don’t want to do). Instance discovery kind of sucks, you can’t even search on the main join Lemmy page.
Looks like my instance got hit with a bot. I had email verification enabled but had missed turning on captcha (captcha enable should be up with enabling email verification settings). The bot used fake emails so none of the accounts are verified, but still goes towards account numbers. Is there really any good way to clean this up? Need a way to purge unverified accounts or something.
It’s a Plex alternative, I don’t know about better. IIRC it’s a fork of Emby. I try both usually a couple times a year, but there’s always something that gives me issue and I just stay with Plex.
Also, seems kind of silly, but the name is just dumb. Neither my wife or I want to audibly say “let’s watch something on Jellyfin”.
Assuming you don’t want to expose these services directly to the internet (I don’t recommend it) then you want to set up a VPN to connect back to your home network. Wireguard or OpenVPN are the most commonly used. As far as guides that will depend where/how you want to run it.
Something like Zoho is only $12 a year per hosted email address.
The cheapest CyberPower/APC that is pure sine wave should be just fine.
Lots of cheep SFF/thin client machines on eBay.
Sorry guys, it’s because I just bought another donation today. This really sucks, Google Domains was easy to use and cheap.
Been using Zoho for years, cheap and reliable.
