[opensuse] using old cell phone as a server

Then get a cell phone. (Or do you call them 'mobiles' like the Brits?)
Possibly one more than 3 years old.

My experience is that a phone-under-contract *might* get an update from your
service provider the first year, but not thereafter. I have perfectly good
phones now six years old whose only shortcoming is that they pop up an advert
for a casino, game or financial investment on every transition. I'm sure they
would serve well as some sort of server where you don't need to look at the
screen and these adverts.

Heck, I've used my old Newton as a web server on the 'net and even my old crappy
S2, the model before the one trump uses to tweet, is immensely more powerful,
even if its handwriting apps come nowhere near the capability of the old Newton.

Android can act as a Web server because it requires very little processing power
to run a site. You can use it to host a family site or just storing pages
locally. A Web server uses the HTTP protocol and while is easy for Android to
run, may be difficult to setup depending on what you want to do with it.

File Server

A file server is pretty straightforward and easy to run because all it does it
create a directory where you can upload and download files from. While Android
devices don’t have too much space, many can be expanded with MicroSD cards or
external storage and a file server is a great way to store files of all shapes
and sizes with it. A file server typically uses the FTP protocol.

I picked up a handful of 256G MicroSD cards for about $5 each. Real crap. They
work in my phones, tablets and even my cameras (but are a bit slow) but for some
reason are unreadable on my PC. Strange that, eh? And the spec on the phones
say that 64G is the max but it seems not to be the case. Errors? At low speeds,
apparently not.

But hey, suddenly I have a few servers!

The researchers propose networking old cell phones together on server racks,
using only their system on chips to run computations. Intriguingly, they suggest
that nothing physically needs to be done with the the phone itself. In fact,
there could be benefits to leaving it intact. For example, the batteries on
board could be used to even out energy usage during periods of peak demand on
the grid (a benefit that comes at no extra cost). Further, phones rendered
unusable to people because of badly damaged screens would work perfectly fine in
a server, as long as the processors still work.
