Deafheaven played in Paris again tonight, in the belly of a boat on the Seine. Absolutely phenomenal live band!

¡Vamos España! Because Argentina mustn't win again. And because Trump, who wants to hand over the trophy, will have to give it to Spain.

Sorry, muss sein: Terrawattstunden (TWh) richtig? (Watt ist eine Leistung, also Energie pro Zeit (Joule pro Sekunde, um präzise zu sein). Man muss das mit einer Zeitdauer multiplizieren um wieder eine Energiemenge zu erhalten. Dafür wird gern eine Stunde hergenommen.

I don't throw pennies because as a middle-aged romantic who's perfectly happy with his own squeezebox server, I refuse to get a streaming subscription. Is there a service that doesn't totally screw artists over?

Dr. Stefan Haessler @stefanhaessler.de · 31/03/2025

But I bought the record in an actual store. Streaming makes the band more money? I like to believe that those 36€ I paid for the physical record contain a sum reaching the band that corresponds to thousands of streams - feels like more than a lifetime. But maybe I'm wrong?

Why do vinyl records no longer come with download codes? This sucks. I'm paying big bucks for that music so why can't I have it in a digital format like I used to?

You indeed should, it's an astonishing film. Not in a "big impressive" way, but a delicate and poetic one. And it touches kids and adults alike.

Hi everyone. The Onion, with the help of the Sandy Hook families, has purchased InfoWars. We are planning on making it a very funny, very stupid website. We have retained the services of some Onion and Clickhole Hall of Famers to pull this off. I can't wait to show you what we have cooked up.

The Onion Buys Alex Jones’s Infowars Out of Bankruptcy

The satirical news site planned to turn Infowars into a parody of itself, mocking “weird internet personalities” who peddle conspiracy theories and health supplements.

The extreme-right government of the Netherlands is slashing higher-education and research budgets. And, as if to make their xenophobic lunacy even more obvious, want to start prohibiting teaching in English.
