Voor alle agressieve schuimbekkende mentaal uitgedaagden die vandaag door 020 marcheerden met foute vlaggen, hitlergroeten bedreigingen en scheldpartijen: jullie zíjn Nederland niet en zullen het nooit worden ook. Jullie zijn schandvlekken met een hoodie.

Website/device age verification is a privacy and security nightmare and everyone who tells you that this is a solved problem is lying to you.

Ok, de regel is: zij eten vanavond en kletsen gezellig. Morgen doen ze inhoud. Dus ik heb morgen weer een dagoverzicht voor jullie (met een aantal bizarre zaken die in NL nu niet in het nieuws zijn merk ik), maar vanavond mogen we memen.

Look people, no matter how much we destroy the Earth by polluting it with CO₂, microplastics, PFAS, etc. everywhere, and even if AMOC shuts down and both the Greenland and Antarctic ice sheets melt, the Earth will still be infinitely more habitable than Mars. Mars is a shithole and we're not going.

Always good to talk to Mikko, he's always interesting but this career change was a surprise. That said, with Russia on the border it's a perfectly understandable move.

"I do believe anti-drone technology maybe has more importance, and more meaning to it, right now with the war raging on."

There wont be a super advanced AI that suddenly hacks ‘all the computers’ ever.

Unpopular opinion?

It’s always “We launched these tardigrades into space!” “We froze them to absolute zero!” “We threw them into an erupting volcano!”

Never “We took these tardigrades on a holiday. They’re getting tiny massages and sipping little umbrella drinks on the beach.”

NL could easily commit to producing 10k drones per months to help Ukraine.

I'm annoyed to see that there is no sense of urgency.
