  • Good discovery tools are essential on a federated platform. An important part of twitter, facebook, and reddit success is/was that that they were the place for their particular style of content. You had a pretty good chance of being able to discover your old high school friends, because they were on the one platform. Then the (early) algorithm started discovering for you all the obscure content similar to your history.

    Discovery has to work differently in a federated system. You can search for communities on Lemmy, but if your instance doesn’t already have someone subscribed to a community, then you’re not going to find it.



  • Depending on the board in your mini-server, you may have enough SATA ports to plug in directly. I have a system similar to what you’re describing (N100 with 4x 2TB HDDs with 1.5TB data): 2 of those drives are set up in RAID1 (mirror), and once a month, I plug in one of the spares, rsync the array to it, and unplug it. Every 3 months or so, I swap the offline drive with an offsite drive. I used to use a USB dock for the offline drive, but I got a 3-bay hot-swap enclosure to make the whole process faster and easier.

    The server shares the array via NFS and SMB, and it is absolutely a NAS for all my other systems.

    If you expect to exceed 2TB data within 2 years, then you’ll need to replace all 4 of those 2TB drives in 2 years. You might, today, get a pair of 4 TB drives and one 2TB, use the 4TB as your main storage, the 2TBs as rotating backups, and wait until you actually outgrow 2TB to upgrade the backups.


  • I see you’re getting lots of advice just to use c/selfhosted as a free consultant. That’s good advice if you’re self-motivated and focused.

    If you want someone to be a coach through the process, to keep you focused and moving, that’s a) a slightly different skillset and b) worth putting in the description. I mention this only because I have a bunch of aspirational projects on my to–do list that have just sat there for literally years because of perfectionism, anxiety, and maybe some undiagnosed ADHD. I’ll also counter by noting that a lot of people, this time of year, buy a gym membership on the theory that spending the money will somehow force them actually to go to the gym, only to find that spent money is not actually a motivator.



  • If you want it to be an actual community service, then you want it to be something that outlives your residence, your tenure as event coordinator, and your interest in being the neighborhood IT guy. It’ll be much easier to transfer control of a VPS to your successor than to give them hardware that also hosts a bunch of your personal services.

    You can start with a very small, nearly free VPS while you recruit users & scale up as (if) anyone bites. Probably even get the HOA to pay for it.

    I got my Pi4 to be a media player - LibreElec or Kodi - for my old, not-smart TV. It plays my library of CDs&DVDs, frontend for OTA TV, and a variety of streaming services. Fanless, so it doesn’t distract from audio, low power, so I don’t mind leaving it on 24/7. You can configure it to listen to a USB IR receiver, but I control mine from phone via web. The actual media library/NAS and tvheaded run on an old desktop in another room.

    My favorite thing is all the sensors you can hook up. Adafruit & Sparkfun have a wide array of sensors with breakout boards for simplicity and well documented python libraries. I started just logging temperature, humidity, then air quality, CO2 to my own database and web page, but eventually expanded to full HomeAssisstant system.

    Pihole.



  • A lot depends on how many users you expect and how much media you expect. For one or two users with that stack, transcoding media is really the only CPU load. If most of your media is already in your desired format, then that’s not a big deal.

    My stack is pretty similar (no *arr, plus tvheadend, homeassistant and a kodi frontend) for two users and it sits near idle all day long. It runs on an N100 NAS system off Aliexpress with 16GB and will transcode 1080p to x264 at just about playback speed… System runs from a 100 GB nvme, with a couple half-full 4 TB WD Reds for data. 35-ish Watts, maybe an extra 5 when actively transcoding. Used to be ~150 USD,

    If you want a lot of 4k content, then I’d definitely go with the GTX 1660.






  • My HA runs on a Pi for various reasons, including GPIO devices, but I’ve moved its database to the ‘big’ server. That means a lot less load on the SD card, no loss of data if the card fails, and just generally feels like a better way to do things. As I’ve accumulated containers, I don’t like that each of them runs its own database when I could just have one database to manage & backup, and not have a lot of replicated overhead.




  • My problem with chains of trust is the Kevin Bacon problem. Sure, I trust my friends, but some of their friends can be a little sketchy. Plus, they don’t have any direct social contact with me, nor any personal consequences for betrayal. And nevermind the sketchy friends of the sketchy friends.

    Federation has its uses, but trust is not one of them.


  • Personally, I try to avoid wifi devices, because they tend to communicate through a central server, and it’s harder to be sure they aren’t secretly phoning home. Zigbee and Zwave intrinsically lack internet connectivity, so they are necessarily local-first. My network is Zwave - no experience with zigbee - and it’s been great. Devices all have a little QR code that you can scan to add the device to HA, whenever the device gets powered up. Good range of available devices, from switches & lights to environmental sensors. Most of my devices are Minoston or Zooz, bought from their websites; haven’t had any trouble. Honeywell thermostat. Aeotec outdoor thermometer.

    I run HA in a container on an RPi, and I have some sensors running off the Pi’s GPIO. Actually started with the GPIO sensors and only got HA running because its visualizations looked easy. Those sensors include temperature, CO2 and airborne particulates.
