  • 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.

    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.

  • 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.

    Custom Emoji Vulnerability

    centennialstate.social Lemmy.world (and some others) were hacked - Colorado

    While I was asleep, apparently the site was hacked. Luckily, (big) part of the lemmy.world team is in US, and some early birds in EU also helped mitigate this. As I am told, this was the issue: - There is an vulnerability which was exploited - Several people had their JWT cookies leaked, including a...

    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.

  • 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?

    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!

    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 i
