Another .NET 10 passkeys post! The server's origin is used to generate passkey credentials. A credential signed for one app can't be used elsewhere.
What about subdomains? Or multiple domains?
I looked into it for you.

Denemarken trekt voorstel voor ‘chatcontrol’ in na felle kritiek: ‘Druist tegen alles in waar Europa voor staat’
Denemarken trekt voorstel voor ‘chatcontrol’ in na felle kritiek: ‘Druist tegen alles in waar Europa voor staat’
Een Deens voorstel op Europees niveau om de verspreiding van kindermisbruikbeelden op berichtendiensten en sociale media aan te pakken, stuitte op zoveel weerstand van verschillende landen dat het niet eens in stemming werd gebracht. Denemarken moet daarom terug naar de tekentafel.

Two nights of 3:45am alarms, blazing full moon lighting the sky like daytime and washing out the light of everything else, comet included. Then two days of post-processing battles, as comet processing is maddeningly tricky.

Tja we hebben alles zo lang vooruit geschoven er alleen nog maar pijnlijke oplossingen over zijn. Als er überhaupt oplossingen geboden worden. Ik hoor van de linkse partijen zeer teleurstellend vooral retoriek daarmee gaan ze t niet winnen
Doorrekeningen partijen: cadeautjes voor gezinnen, staatsschuld explodeert
Doorrekeningen partijen: cadeautjes voor gezinnen, staatsschuld explodeert
Het zijn vooral partijen alsGroenLinksPvdA, D66, CDA, ChristenUnie en Volt die de belastingen op vermogen en winst verhogen bij een mogelijke regeringsdeelname. Dat blijkt uit de doorrekeningen van het Centraal Planbureau CPB. Opvallend daarbij is wel dat bij twee van die partijen de economische groei in meer of mindere mate aantrekt: D66 en GroenLinksPvdA. Bij andere partijen, ook die niet spelen met het verhogen van belastingen, zal de groei helemaal niet sneller groeien dan al wordt verwacht.

Reparatie van apparaten moet geen gunst zijn, maar een recht
In 2026 moeten EU-lidstaten een Europese richtlijn invoeren die burgers het recht geeft op reparatie. Kunnen we dat recht dan ook echt uitoefenen? Mathijs Bouman betwijfelt dat.

A few things motivate this:
* raw UDP packets can get lost in transmission. Which means no holepunch 4 u. QUIC gets us ACK’d packets.
* encryption is a good thing.

Did you know that we like QUIC?
We like it so much we're replacing our use of STUN over UDP with QUIC address discovery!
We've contributed an implementation of that standard to the quinn #rust library, and are now using it.
