  • There are some clients that support the latest version of OMEMO, but yes, since the most popular ones do not, you end up using the older version most of the time. That said, the older version is not generally unsafe, it basically is the same as WhatsApp or Signal are using. The newer version is just somewhat better as it includes some lessons learned from earlier attempts.


  • E2ee is not everything, as most of the privacy sensitive metadata can still be collected. Sure it is nice to have, but even more important is that you can chose a trustworthy server operator or run your own. XMPP allows doing that, but it has some weaknesses with client implementations and so on.

    I am a bit biased and would say all in all XMPP is probably the best option right now, but it depends on your specific priorities. It certainly has some rough edges though.






  • That is why I said it depends. There are many places where electricity cuts for a short duration are quite frequent. Often you don’t even notice it, but a 24/7 server would be effected.

    In general, I think the risk of laptop batteries catching fire is overstated especially if you limit the charge to 80% or so. So weighting these two issues against each other you can come out either way, but I think for most places it will come down towards a UPS being nice to have.





  • On another technical note: I finally got around installing the solar-panels on the roof of the place that acts as the “datacenter” for the SLRPNK servers. The servers were already running on battery charged at night since March of this year (mostly wind and geothermal grid power then) and now I will try to run them fully on solar-power.

    It’s not a complete off-grid system, so if there is a power shortage it will still pull from the grid (which at peak times is sadly still 60% fossil fuel here), but I am reasonably confident that most of the time this will not be necessary as the battery has sufficient capacity.
