Want to develop your own chat app that works via Bluetooth, Tor, and pigeons? Or do you want to extend Briar to work via LoRa, Wi-Fi Aware, I2P, WhatsApp, whatever? Or Android is constantly suspending your app in the background?

I've written down some pointers to Briar's source code and research with pieces to start with. Inspired by an amazing #39c3, because sharing is caring.

Ihr kennt ja sicherlich diese Übersicht von Congress #Designs (u.a. vom #39c3 ): https://designs.events.ccc.de/
Oder auch die #Chaos #Sticker Collection: https://mwarning.github.io/chaos-sticker-collection/

Wir haben auch ein paar Designs gemacht und wollen von euch unbedingt Feedback dazu haben. Wie findet ihr die Designs? (Es kommen in den nächsten Tagen noch mehr) Würdet ihr was daran ändern? Würdet ihr solche Sticker haben wollen?

Achtung, jetzt wird’s nerdy: Die Totalsanktionen bei verpassten Terminen, oder die “Nichterreichbarkeitsfiktion”, sind eines der Grundübel der neuen Grundsicherung. Heute stelle ich euch einen der führenden Köpfe hinter den Verschärfungen beim Bürgergeld vor. Als ehemaliger Vorsitzender des Bundessozialgerichts könnte man viel von ihm erwarten – aber weit gefehlt. Auf das Verfassungsgericht gibt er nicht so viel, er schreibt Gutachten für das neoliberale und INSM, eine CDU-Lobbyorganisation, und ist Linnemann-Flüsterer der ersten Reihe. Rainer Schlegel.

@cstross that might be the right moment to do, what @pluralistic argued in his " A post-American, enshittification-resistant internet" talk at #39C3 for - breaking free from the stranglehold of the anti-circumvention laws and all the trade agreement related issues and dependencies connected to them:

I showed that chart📉 in a presentation at #39c3 as an example of how to utilize UNFCCC data, joking that there probably aren't many people asking themselves what the N2O emissions of Caprolactam production are, or what that even means. Hours later, I read that Domo Caproleuna, a German Caprolactam producer, had filed for bankruptcy.

They aren't alone. Many relatively climate-friendly Caprolactam factories in the EU🇪🇺 have been shut down or are in danger.

Remember the talk I purposed for #39c3 about the push for DRM, firmware lock-in and surveillance on 3D printers by gun control lobby groups in the name of preventing gun violence?

Well the first bill is here for exactly that. It requires manufactures of 3D printers to prevent the use of 3rd party firmware and the introduction of an algorithm that guesses if a print is a gun part and prevents the printer from printing in that case.

Are you interested in learning more about finding your position with a sextant and my slide rules? Are you curious how to calculate the current time based on the position of the moon? Do you want to hear me say "uhm" a lot? Then you might enjoy this poorly produced followup to my #39c3 talk explaining some of the more complicated bits of celestial navigation: https://www.youtube.com/watch?v=LcTrZdWb5fc

There was a #39c3 talk on PTP that looked interesting, but had ai slop images and the presenter said they used chatgpt to code some of their presentation (and which they blamed when that part of the demo failed). And this morning there was a potentially neat article about hosting websites on a SPARC1, which diverged into unrelated MCP sloperations, so the whole article is suspect and not worth sharing. More disappointing evidence for the #DeadInternetTheory...

Redstar is a #hacker + #communist group, formed at #39c3.
We continue to meet consistently every week online, doing structured work in an international setting.

We're inviting anyone interested to participate in our reading group, about to start.
