Been using Zoho for years, cheap and reliable.
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.
Centennialstate.social updated to Lemmy 0.18.4
Updated to Lemmy 0.18.4, see release notes here: https://github.com/LemmyNet/lemmy/blob/main/RELEASES.md
Centennialstate.social updated to Lemmy 0.18.3

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.
Where is Bandimere Speedway moving to? Family gives plan insights
Out near DIA was the obvious choice. Just not going to be the same, but better than no Top Fuel at all.
Centennialstate.social updated to Lemmy 0.18.2
Updated to 0.18.2, which includes fixes for the recently found vulnerabilities. Also updated with Ansible this time to get the Nginx config updates, which I think fixes some federation issues with kbin and Mastadon.
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.
Custom Emoji Vulnerability
For those that are aware, some Lemmy.world admin accounts were hacked using a known Lemmy vulnerability based on custom emojis. There are NO custom emojis configured for this instance, so no concerns regarding this vulnerability for this instance.
So I kind of have a problem with a lot of these "save the bees" places that push honeybees. Honeybees are not native to North America, they are also not really at risk because they are so commercialized. What ARE at risk are native bees, which honeybees compete with and push out.

The best thing you can do to help bees is plant bee friendly gardens.
Lemmy v18.0 Plan
At the moment I do not plan on updating to v18.0, since it removes captcha. Captcha should be back in v18.1 though, at which point I will update!
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.
Wow, I'm closer to Roxborough, had no idea. Luckily just some small hail and hard rain.
Colorado Lemmy Server
Hi everyone, just wanted to make people aware of a Colorado instance I’m trying to get going. If anyone is interested feel free to join!
I think /r/Denver might be more open to it, I know @SpezCanLigmaBalls got permission to post there about the Denver community on lemmy.world.
Colorado Lemmy Server
Hi everyone, just wanted to make people aware of a Colorado instance I'm trying to get going. If anyone is interested feel free to join and also start a Colorado Springs community!
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.
For a basic personal server you really don't need much. I mess around with one on Azure using a Standard_B1s VM (1vCPU/1GB RAM) and it ran fine. Cost like $7.28 a month.
Simplest is to just spin up an Ubuntu VM in Azure and install Lemmy using Ansible.
I use Zoho, it's only $12 a year.
I messaged the mods of /r/colorado and unfortunately, they declined, citing privacy and security concerns with the fediverse.
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.
RTD will be free July and August
Looks like RTD will be free again this summer for both July and August!
I agree. The more familiar I get with Lemmy under the hood it's apparent they weren't ready for this level of users, and there's a lot of rough edges. I also don't plan on quitting Reddit cold turkey, so definitely see Lemmy as something that can coexist as an alternative until is gets polished.
Reading through the r/Denver threads about the blackout it's clear vast majority of users are annoyed by it and don't give a shit about the API stuff, so probably best to avoid that topic altogether. The angle should be the general direction reddit is heading and giving power back to the users and their communities.
Server Information
Server
This instance is currently being hosted using Vultr on a server located in Dallas. Specifically, it's using a cloud compute server with the following specs:
- AMD High Performance
- Ubuntu 22.04 LTS x64
- 1 vCPU
- 1 GB of memory
- 2 TB of bandwidth
- 25 GB of NVMe storage
- Attached storage: None
Auto backups are enabled and configured for every other day at 2AM Mountain Time. Total monthly for hosting is currently $7.20 a month. I chose Vultr for its combination of price, ease of use, and ease of upgrading. With a couple of clicks I can upgrade the server up to 12 vCPUs and 24 GB memory.
Domain
I currently have the domain centennialstate.social registered with Google Domains at a cost of $30 a year. Unfortunately, the same day I purchased this domain Google announced they were selling off their Domains service to Square Space. I have to wait 60 days from purchasing before I can transfer it, at which point I will be transferring it to CloudFlare at an unknown cost. If it's like my other domain I transferred then it might actually end up being cheaper.
I did not have any luck getting email working with postfix so I set up email with Zoho, which costs $12 a year. Currently email is just used for new account email verification and password resets. I don't plan on really monitoring the inbox.
Please let me know if you have any other questions about this server/instance!
