A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Would a cheap, used raspberry pi 3 make for a good test server for following random self hosted tutorials? (lemmy.ml)

In my self hosting journey, which is very much in its infancy mind you, many times I've longed for an extra machine I can use to try following tutorials on setting up samba shares, home assistant, what have you without having to worry about messing up my main machine and having to clean up after myself. As for acquiring such hardware on the cheap, I keep reading how the laptopocalypse w/ Windows 10 end of life will flood the markets w/ literally unlimited free e-waste bro!!! But my own experience hunting these EOL once in a lifetime deals has been more frownie face than happy face. Lots of $100+ listings and, idk that just seems like a lot to ask for something like that.

So just for fun I searched eBay for "raspberry pi" and came across this listing for a raspberry pi 3 w/ 1 GB RAM for $25. 1 GB of RAM seems like not very much, but then again I'm not trying to break the sound barrier here, I just want something that can sit on my desk basically unnoticed and hook it up to my KVM switch so I can switch to it from time to time, like whenever I want to try following a tutorial and not losing any sleep if I fail (and I fail often).

I've also kinda always had a little bit of envy from not being in the raspberry pi club, so this is my shot at getting into the club. I think I'm going to spring for this one, so my question for the audience is, but like honestly am I about to piss $25 down the drain? Would this be good enough for my purposes or is the 1 GB of RAM going to bottleneck me like a boss?

Sorry for the run on sentences, my brain's tired today.

Raspberry pis are an easy intro to actually using computers (instead of using something like windows).
Raspbian is great (based on Debian) and there is a HUGE community for it.

So yeh, it's a great started for $25, as long as you have a PSU and SD Card. And an hdmi cable + monitor + keyboard at your disposal (and a mouse if you are installing a desktop environment (IE something like windows, whereas headless is a full screen CLI).
And don't get your hopes up for a windows replacement.

But.... Why not run a Virtual Machine? If you have a windows machine, run VirtualBox, create a VM and install Debian on it?
That's free. You can tinker and play.
And the only thing you are missing from an actual raspberry pi is that it isn't a standalone device (IE your desktop has to be on for it to be running), and it doesn't have GPIO (ie hardware pins. And if this is your goal, there are other ways).

If you really really want a computer that is on all the time running Linux (Debian, a derivative (like raspbian) or some other distro) - aka a server - then there are plenty of other options where the only drawback is lack of GPIO (which, in my experience, is rarely a drawback).
And that is literally any computer you can get your hands on. Because the raspberry pi trades A LOT for its form factor, the ethernet speed is limited, the bus speed is limited (impacting USB and ethernet (and ram?)), the SD card is slower and will fail faster than any HDD/SSD. The benefit is the GPIO, the very low power draw, and the form factor - rarely actually a benefit.

I'd say, play around with some virtual box VMs. See what you want, other than Fear Of Missing Out (things like PiHole? They run on Debian, or even in a docker container). Then see if you actually want a home server, and what you want to run on it.
It's likely you won't want a raspberry pi, but a $150 mini pc that can actually do what you want.
