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.

The future of selfhosted services is going to be... Android?

Wait, what?

Think about it. At some point everyone has had an old phone lying around. They are designed to be constantly connected, constantly on... and even have a battery and potentially still a SIM card to survive power outages.

We just need to make it easy to create APK packaged servers that can avoid battery-optimization kills and automatically configure an outbound tunnel like ngrok, zerotrust, etc...

The goal: hosting services like #nextcloud, #syncthing, #mastodon!? should be as easy as installing an APK and leaving an old phone connected to a spare charger / outlet.

It would be tempting to have an optimized ROM, but if self-hosting is meant to become more commonplace, installing an APK should be all that's needed. #Android can do SSH, VPN and other tunnels without the need for root, so there should be no problem in using tunnels to publicly expose a phone/server in a secure manner.

In regards to the suitability of home-grade broadband, I believe that it should not be a huge problem at least in Europe where home connections are most often unmetered: "At the end of June 2021, 70.2% of EU homes were passed by either FTTP or cable DOCSIS
3.1 networks, i.e. those technologies currently capable of supporting gigabit speeds."

Source: https://digital-strategy.ec.europa.eu/en/library/broadband-coverage-europe-2021

PS. syncthing actually already has an APK and is easy to use. Although I had to sort out some battery optimization stuff, it's a good example of what should become much more commonplace.

You can get a wyse thin client on eBay for $50, and if you're clustering the pis it's not $50 anymore, so you can get a real computer on woot in the $150 range.

Either of those options will run circles around a pi/pi cluster.

[–] [email protected] 1 points 1 year ago (1 children)

holy shit I haven't thought about that webside in over a decade. Do you have personal experience purchasing self hosting stuff from there?

[–] [email protected] 1 points 1 year ago

I've bought a couple old SFF PCs and tablets from there for low powered workstation stuff.

For self hosting I end up with rack mount dell servers when the prices fall off a cliff; right now it's the 13th gen stuff that's super cheap.

[–] [email protected] -5 points 1 year ago (2 children)

Please learn to read. Again. I thought I wasn't on Reddit anymore.

$50 for a pi. Not for clustering. For one. That's it.

An X86 PC is gonna cost you hundreds. That's how I can cluster rpi, for the same cost. I hope you now know how to do basic math.

[–] [email protected] 3 points 1 year ago (1 children)

Insulting my reading ability and math skills would work better if you weren't making a fool of yourself.

I gave you an example of a $50 x86 PC and mentioned the more expensive options because you brought up building a pi cluster in your first response to me, at which point you're not talking about spending $50 anymore.

The main point is that either the thin client or the slightly more expensive computer will runs circles around your pi(s) for the same price.

[–] [email protected] -5 points 1 year ago (1 children)

I gave you an example of a $50 x86 PC

No you didn't. You gave an example of a >= 200 x86 PC... So, like... That's why I even suggested clustering. To match the cost of your claim.

Oh, so like... A worthless fucking machine... Sure. You use that. Let me know how many minutes that lasts, on your fucking Celeron lmao

And in any case, that's a used vs new ... Like.. bruh, their new ones start at 700... I can buy 14 pis for that...

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago) (1 children)

A worthless fucking machine

Hey, that's what I always end up thinking when I try to use a pi for anything.

But if you actually check the numbers, that has pretty similar specs to the Pi4 but supports virtualization and has more ram. And the wyse runs on a real hard drive instead of an SD card or some janky USB setup.

[–] [email protected] 0 points 1 year ago* (last edited 1 year ago)

or some janky USB setup

TIL nvme is a janky USB setup

But if you actually check the numbers, that has pretty similar specs to the Pi4 but supports virtualization and has more ram. And the wyse runs on a real hard drive instead of an SD card or some janky USB setup.

But also general reply to that. Similar specs to the pi4, sure, but what about the 5 that is 3x as fast? It also has the same amount of RAM that the small 5 does. And by the way the link you posted, it runs off of an emmc drive... As in it's effectively an SD card... Just, embedded. (Hence the "e")

This isn't even true. A Pi sells for 50$ yes, + USB cable for power + USB power adapter + case + whatever else money grab.

A second hand HP mini with an i5 7th gen CPU that is WAY faster comes with everything including 8 GB of RAM and 256GB of SSD (or better if you get a good deal) for around 80$. Tell me about your math again...

How's the power consumption compare between two performance equivalent setups? (Genuine question, it's something I'm trying to determine for my self-host use-cases).

My first RPi is for Joplin to replace OneNote. My current server runs 24/7 and costs about $1/day for power (it provides other services too). I haven't calculated my Pi power consumption yet, but it's running on a 2.5 watt power supply, vs my server 700 watt (of course, these are both peak measurements).

Given my self-host stuff will spend 99% of its time at idle, it seems like Pi has a massive advantage. But of course that all depends on how things are used and setup.

[–] [email protected] 1 points 1 year ago (1 children)

The raspberry pi, like all RISC chips, uses much less power.

In fact the super computer summit runs on powerpc64 which is a RISC chip, that's a big reason why its power consumption for a super computer is so low.

[–] [email protected] 1 points 1 year ago

I hadn't considered the RISC angle. Does RISC consistently use less power than CISC at given operations levels (MFLOPS, for example), or is there another/better way to make a power-consumption vs operations/performance comparison?

I realize this is kind of esoteric for my use-cases, but it would be useful for making projections to see if spending X dollars on Y number of Pi's recoups the investment over a given period, just in power consumption.

E.G. If I can reduce my power consumption by 70% by switching to 3 Rpis, then I can recoup their cost in 2-3 years. Since my server needs replacing anyway, this seems like a no-brainer.

Yeah, a second hand old as shit hp, that'll die on you so quick. There's a reason that hp is selling for so cheap. HP is garbage, unless you're buying their actual servers...

Edit: also all the "cash grab" parts.. you probably already have those parts just lying around doing nothing.

Not my experience. At all.

Edit: also all the “cash grab” parts… you probably already have those parts just lying around doing nothing.

Yes I sure have a proprietary adapter for their PCIe connector and a Pi case lying around. Just the case its about 30€ and suddenly it becomes as expensive as a second hand mini PC for 1/10 of the performance and reliability. See the problem now? Even with the power adapter, the RPI is picky and will require a decent thing that is usually more than your average smartphone.

This is self hosting... You're telling me you or one of your friends don't have a printer to print a case for less than a dollar? Shit, pay for shipping and I'll send you a case.

PC for 1/10 of the performance and reliability.

That's not my experience at all. I mean the other user already posted a PC you can buy for the same price as a pi. It's about as good as a 4, the 5 is 3x that speed.

See the problem now?

A metal chassis from an HP Mini will be always better than something 3d printed...

That other guy could've done better.

https://www.ebay.com/itm/285465761346

HP ProDesk 600 G3 Mini Intel Intel i5-7500T 2.7GHz 8GB DDR4 256GB SSD

There are similar deals in Europe, usually from Germany.
