Irgendwie interessant: Anscheinend erreicht das Gehirn erst mit ~32 Jahren seine Erwachsenenphase. Was jetzt irgendwie gefühlt wirklich stimmt, aber dann halt auch total in Frage stellt, dass man rechtlich mit 18 als Erwachsen zählt

Der Drucker hat mich übrigens vor 4 Jahren 150€ gekostet. Alleine dieser Druck hat jetzt 10% der Anschaffungskosten wieder eingespart. Diese Fähigkeit, einfach selbst Custom-Plastikteile zu drucken, ist wirklich absolut großartig.

Ich habe soeben einen volkswirtschaftlichen Schaden am Bruttoinlandsprodukt und am Binnenkonsum von 14,90€ angerichtet, indem ich mir die verloren gegangene "Waschmitteltrennklappe" einfach selbst gedruckt habe.

Was eine unglaublich dumme Konstruktion, dass man essentielle, für die Funktion nötige Teile einer Waschmaschine, die ja zig Jahre halten soll, in klein, aus Plastik und leicht zu vertrödeln baut. Das gehört fest verbaut

A startup is putting military-style drones in high school ceilings. Ceiling-mounted. Charging. Waiting. And when something happens, a pilot in Austin, Texas, decides whether to deploy pepper gel on your kid's school. I'm not saying the problem isn't real. It absolutely is. But read that back.... in schools. We've taken a Ukrainian battlefield tactic against Russian soldiers and ported it to Deltona High School in Florida. The co-founder literally said the idea came from watching drone videos of the war in Ukraine. The chief pilot described it as "cheating in a video game after you die." These are children.

Here's what's not in the headline:

🔒 The drones use an encrypted connection — but the article notes they're potentially vulnerable to cyberattack. A compromised drone in a crowded hallway isn't a security tool; it's a weapon pointed in the wrong direction.

⚖️ Mithril reserves the right to act independently during an attack, without waiting for law enforcement. A private company operating remotely is making use-of-force decisions at a school.

💰 Florida and Georgia approved $500K+ each for this. A group of Texas parents raised $200K more. That's real money going to ceiling drones instead of mental health services, counselors, or de-escalation programs.

The ACLU said it plainly: when force becomes a zero-risk remote action, it gets overused. Axon tried a Taser drone for schools in 2022, and its own ethics board killed it. Mithril is picking up where that got dropped.

I teach cybersecurity. I've spent years in boardrooms helping organizations think through risk. And the risk calculus here isn't just about whether the drone works. It's about what we're normalizing when we turn schools into drone-monitored combat zones and call it progress.

"This is the future," said the sheriff's captain.

I hope not.

Bei 15.000km im Jahr fährt man in den 2 Monaten des Tankrabattes dann 2500km. Bei 7l/100km verbrennt man also 175 Liter Dinosauriersaft. Wenn sie weitergereicht werden, bringen die 17 Cent Rabatt dem Fahrer dann 29,75€ an Ersparnis.

You know what, I'm trying to comment on this but I just can't think of anything funnier to say than how this is sure to turn out

Solar panels are creating an unexpected effect by forming rainfall clouds and thriving oases in the middle of the desert

The article published in Science has detailed how massive solar arrays in the Sahara Desert have started to trigger increased rainfall and vegetation growth.

They drastically lower the temperature around the sand that they sit on, effectively “greening” the desert. As the warm air around the panels has nowhere else to go but up, they naturally form massive rainclouds in a part of the world known for its dryness.

A recent study has found an unexpected benefit from the undisputed king of the renewable energy sector as solar panels are creating rain clouds in the desert.
