perhaps a stupid question, but are there bridges for XMPP ? My impression is that XMPP is as good as empty (I do use it mainly as a federated service). Is there still a lot of active development on the XMPP side of things?

I do not understand your point with 'you cannot change the URL'. If you use matrix as non-federated and just the only user, what is the problem that you need to change the URL when you need to set up a new server on a new URL? Not being able to change the server at the same URL seems like a logical concequence of authentication, be it for server-to-server communication as for client-to-server communication.

A URL 'Free up to some-end-date'. ???

Phishing link? 🤔

Big international companies have no problem to create pseudo "national" versions of services if they can make more money with it.

So there should not be a problem for the social media companies to create versions that meets local legislation.

If you create a product and want to sell it in a certain market, you must also adhere to the laws of that country/region.

Protection of citizens against unjust ruling by a court is a protection-principle of democrary.

Why would you grant such a protection to an organisation aimed at destroying democracy (X/twitter)?

As a sidenote. This reminds me of a discussion I haver every so often on "tools that make things to easy".

There is something I call "the arduino effect:. People who write code for things, based on example-code they find left and right, and all kind of libraries they mix together. It all works .. for as long as it works. The problem is what happens if things do not work.

I once helped out somebody who had an issue with a simple project: he: "I don't understand it. I have this sensor, and this library.. and it works. Then I have this 433 MHz radio-module with that library and that also works. But when I use them together. It doesn't work"| me: what have you tried? he: well, looked at the libraries. They all are all. Reinstalled all the software. It's that neither me: could it be that these two boards use the same hardware interrupt or the same timer he: the what ???

I see simular issues with other platforms. GNU Radio is a another nice example. People mix blocks without knowing what exactly they do.

As said, this is all very nice, as long as it works

I wonder if programming-code generated by LLMs will not result in the same kind of problems. people who do not have the background knowledge needed to troubleshoot issues once problems become more complex.

(Just a thought / question .. not an assumpion)

OK. That makes a lot more sense.

Thank you for correcting the original post. 👍

I completely agree with your remarks.

For people who are interested in opensource and amateurradio, I propose you have a look at the conferences on that topic.

Overhere in Europe, there are two of them

  • FOSDEM ("Free and Open Source Developers European Meeting") is a yearly event held in Brussels every 1st weekend of February. In the 2024 edition, there was a devroom ("developers room") on SDR and Amateur-radio. https://fosdem.org/2024/schedule/track/radio/

The videos of the talks are online. I propose to have a look at the talks on M17 and on OpenRTX.(*) Also open source hardware is becoming more interesting.

  • Next september, we will be hosting "spectrum24", a new conference on "novel ways to use the spectrum we -as citizens- are able to use. It puts a lot of emphesis on Open-source as yes, most -if not all- of the new projects coming out in amateur-radio are open source.

For this conference, we are at the "cfp" (Call for Presentations) stage. See here: https://spectrum-conference.org/24/cfp

I know that Europe is the opposite side of the globe for you in Autralia. Perhaps there are similar events on your side of the world.

What was that saying again?

"the biggest thread to the safety and cybersecurity of the citizens of a country ... are managers who think that cybersecurity is just a number on an exellsheet"

(I don't know where I read this, but I think it really hits the nail on the head)

The issue is not cloud vs self-hosted. The question is "who has technical control over all the servers involved". If you would home-host a server and have a backup of that a network of your friend, if your username / password pops up on a infostealer-website, you will be equaly in problem!

[-] kristoff@infosec.pub 3 points 2 years ago

The question is .. do we care about THAT 80 % of the people. I would be more then happy if we can have that 20 % of more technical-oriented audience :-)

A /48 is quite overkill for a home customer. Do you have 65536 LANs at home? Here in Belgium, we get a /56.

Hi,

I have also been thinking about selfhoating a jisti-meet server. Just how easy / difficult is it to selfhost it? Do you run it in docker or natively? Linux or some other OS (FreeBSD)?

Hi,

I don't know if this has already been posted here.

Some time ago, I found this 3-part documentary on the cyberpunk genre:

Part 1: https://www.youtube.com/watch?v=sttm8Q9rOdQ (also in the title of this post)

Part 2: https://www.youtube.com/watch?v=0VoX3vr6CCM

Part 3: https://www.youtube.com/watch?v=KczJNtexinY

Enjoy! :-)

HI all,

For people who live in the neighbourhood of Hanover, Gernany. In almost 3 weeks from now, I will give a workshop "Hacking Radio-signals" in the summer edition of hackover 2023. The exact timeslot still has to be decided, but hackover is the weekend of 14, 15 and 16 July.

In the workshop, we will capture, analyse and decode the signal of a 433 MHz remote-control. You do are required to bring your laptop and have some software installed beforehand.

If you are interested, either drop a message in this thread or contact me at the email-address in the announcement
