Jonas Schäfer / is on Nostr

By day, DevOps team lead at Cloud&Heat in Germany.

By night, #xmpp #electronics #embedded #iot #devops #penandpaper #rpg.

I tend to dabble my feet in anything technical I can get my hands on, unless it's proprietary.

Concerned with the state of the world (climate, for one, hatred and war for another), trying not to worry too much about things outside my control.

Interactions, boosts etc. in general welcome.

@npub129g…4kwg Do you happen to know whether there is an equivalent for BTreeMap?

Okay and they just don't believe you that you are not doing that?
And you are not even syncing contact names into the remote roster or something like that?

@npub1w0h…uwua Makes one wonder what exactly the contact permission is for, then.
If you're not allowed to process the contacts locally, and obviously not remotely, why exactly is the permission even a thing?

@npub1sg4…xslc Have you seen https://github.com/PowerDNS/weakforced ? It looks roughly related.

"SMTP Smuggling" vulnerability in Postfix allows to spoof senders even in the presence of some DMARC checks. Configuration workarounds exist.
Also, a wholehearted f* you to SEC Consult, who sat on this since June and disclosed it to some closed-source vendors and MSPs, but could apparently not be bothered to give e.g. Postfix a heads-up, publishing this close to the holidays.
Boosts for awareness welcome.

P.S.: Ich bin hier um zu lernen und freue mich über Kommentare dazu, wie ich ein Bild hätte handwerklich besser machen können, auch wenn es euch offensichtlich oder trivial erscheint :-).

#libreoffice I don't even. The only explanation I have for this is that my computer is also dragged down by the weather.
Yes, I am only typing simple letters.

Yes. @npub14t2…nx8c has a great package for a self-hosted #xmpp server you're ok with docker.
If not, you can still just use prosody. The defaults of everything have improved significantly in the past years.
(And the jabber.org migration certainly helped.)

This. All of this, really. (Replying nontheless to add some "weight".)
I started moving over some of my GitHub repositories last week and plan to move everything I care about eventually.

When I've recently seen people say something like "X killed #XMPP", it seems as if they were not talking about the protocol itself (which, as your screenshot from the XMPP Standards Foundation website shows, is quite thriving).
What they mean is that it they drained users from the federated network into their walled gardens and then closed off federation themselves (gtalk did that, whatsapp never federated in the first place afaik).
It is important to remember that those corporations only do things which are profitable. Opening federation is not profitable on its own.
