No, Revolt checks neither of my boxes unfortunately.

End to end encryption between clients (also for groups) seems to partly address the issue of a bad server. As for self-hosting, any rented or cloud sevices are very vulnerable to an evil maid. So either in-house hosting or locked cages with tamper-proof hardware remain an option.

What’s the protection in the clients assuming compromised infrastructure, like e.g. in https://notes.valdikss.org.ru/jabber.ru-mitm/ ?

It is entirely insecure.

So what’s left? Jabber?

No use cases for this so far.

Mobile service quality is defined by the baseband, which is an immutable blob to the OS. I phone rarely and currently use my old LineageOS phone for it.

I’ve got a support case for my Pixel 7a open due to potential battery issue. If I return it I will buy a different, bigger (6.7") Pixel model. My new Pixel tablet is doing fine so far.

I use tablets to read things when lying down, so notebooks don’t fit.

Matrix (Element), Signal, Telegram. Other stuff probably requires Google services which I don’t use on the tablet. Phone has Google services, but I don’t really use it for messaging other than Signal.

The endgame is that nobody has money and companies go bankrupt. The end.

I’m on GrapheneOS on tablet/phone for time being, but I’m fine going back to a dumphone and a Linux or BSD tablet or convertible.

Marketing. Fresnel lenses are not going to do well with diffuse light.

A billion light years across at 20% lower density. So not stellar neighborhood, way bigger than a galaxy.

It is a billion light years void, not a light day void.

Not power. Electricity. Try primary energy use, be surprised.

Pixel 7a and Pixel Tablet since yesterday here.

On Pixel 9 stock they mention you can disable AIcore in the settings, so I would assume GrapheneOS is unaffected.

Great writeup.

How much is a kWh in your parts? Noise, ambient temperature? You can buy very decent refurbished Lenovo tiny PCs with some 16 GB RAM and 6 cores and half a TB SSD which will run Proxmox and are low power and noise. You can go multi-node Proxmox later if you want to expand. k8s and related are also an option.

DIY few kWp solar payback is about 2 years.

In Germany consumer power is something like 0.4 EUR/kWh, so economics of running power-hungry hardware might be different. Solar PV might change the equation once again.
