Breaking: John Ternus to become #Apple CEO on Sept. 1, 2026. Tim Cook to become Apple Executive Chairman. Official @apple press release apple.com/newsroom/2026/…

Vance's speech in Budapest is truly outrageous: 1. The US vice president campaigns for an enemy of the EU & NATO, but a friend of Putin & China. 2. Vance attacks the EU for pressuring Hungary, but Hungary has received net about 3% of GDP a year from the EU, but it has squandered much on corruption. 3. In effect, Vance argues that the EU should promote corruption just as the Trump administration does. Trump and Vance fight freedom and the rule of law in favor of autocracy, kleptocracy and Russia. US foreign policy has hit the bottom.

@latestincosmos This image seems to be fake IMHO. The spacecraft looks rather like ISS but not Orion.

Get Ready.. Prepare yourself to witness history unfold right before your eyes! 🚀 For the first time ever, the entire Orientale Basin, a massive and mysterious region on the Moon’s surface, has been fully captured thanks to the efforts of NASA’s Artemis II crew. This remarkable achievement marks a huge step forward in space exploration, revealing a breathtaking new view of our celestial neighbor. The clarity and detail in this historic image are absolutely stunning! 🌕🛰️ As we move further into space, it reminds us of the endless wonders still waiting to be discovered.

@Prusa3D Funny 1st April joke 🤣

Introducing Prusa Pro ACU: blog.prusa3d.com/prusa-pro-acu_…

Happy 50. Birthday @Apple! Founded on 1st April 1976 by Steve Jobs, Steve Wozniak and Ronald Wayne. I am grateful for all their products and services that made my life and work easier, more efficient, and joyful.

@RheinmetallAG has nothing comparable which is as efficient at this price point. Even worse it’s CEO Armin Papperger recently mocked #Ukraine for their housewife made drones. Europe cannot wait until Rheinmetall and others get up to speed!

@ihtesham2005 It would be even better if you would name and give kudos to the great developer Yousif Amanuel / @DataScientistPy who has created @terrainkapp. See here its originial post on X x.com/DataScientistP…

This feels like cheating. People pay $30-$50 for custom city map posters on Etsy. Someone just open-sourced the exact same thing for free. It's called TerraInk. Its a cartographic poster engine built on OpenStreetMap data. Type a city. Customize everything. Download and print. What you get: → Any city on Earth via OpenStreetMap → Roads, water, parks, building outlines → Full theme and color control → Custom fonts via Google Fonts → PNG export, print-ready The whole thing runs in your browser. No account. No subscription. No checkout. Self-host it with one Docker command if you want it completely yours. 100% Open Source. MIT License. Live app: terraink.app

@MillieMarconnni It would be even better if you would name and give kudos to the great developer Yousif Amanuel / @DataScientistPy who has created @terrainkapp. See here its original post on X. x.com/datascientistp…

Nobody is talking about this. People are charging $50-$100 for custom city map posters on Etsy and printing them on demand. A developer just open-sourced the entire workflow for free. It's called TerraInk. Type any city on Earth, customize every detail, and download a print-ready poster in minutes. Everything is pulled live from OpenStreetMap roads, rivers, parks, building outlines, all of it. You control the colors, the themes, the fonts, the layout, everything down to the last detail. Export a high-resolution PNG and send it straight to a print shop. No account to create. No subscription to pay. No checkout to click through. The whole thing runs in your browser right now. Self-host it with a single Docker command if you want it completely offline and yours. Etsy sellers are making real money selling exactly this. 100% Open Source. MIT License. Live app: terraink.app

@DataScientistPy @terrainkapp You are awesome! What a fantastic and beautiful app! Many thanks to you for developing @terrainkapp and sharing as open-source!

People usually pay $30–$50 for these on platforms like Etsy. I built @terrainkapp, an open-source map posters creator. I provide the same capability for free. TerraInk is a cartographic poster engine built on OpenStreetMap data. Linke: terraink.app #mapart #maps

shocked, shocked etc

someone built a $96 3D-PRINTED MANPADS rocket that recalculates its mid-air trajectory using a $5 sensor and piano wire its called Project Canard it integrates with distributed camera nodes to triangulate airborne targets and update flight paths in real-time it proves the barrier to advanced hardware has completely collapsed, moving precision weapons from defense labs to consumer garages the entire launcher and interceptor frame is 3D printed in PLA and runs off a standard off-the-shelf ESP32 microcontroller it even spins up a local Wi-Fi network so you can monitor live telemetry and arm the system directly from your laptop

@joeltelling @loyalmoses But the scope of this only in the context of producing firearms with 3D printers or CNC. So that makes sense. Dangerous is everyone is allowed to create weapons on their own!

I tried. No politician would listen. @loyalmoses tried. No politician would listen. Others tried. No politician would listen. WA HB 2320 has been sent to the governor to sign into law. I have no doubt he will sign it. Once this is law, it sets precedent for similar bills in other states. THIS makes the slope very slippery.

BOOM! A stencil I got quoted $20 for now costs $0.01 to make Nobody believed in the 3d printed stencil but it worked perfectly! You guys are all crushed under the boot of big stencil. While I’m liberating the people. Start 3D printing your own stencils, it works!

Everyone’s missing the real story here. Meta’s Ray-Ban glasses need human data annotators to train the AI. When you say “Hey Meta” and ask the glasses to analyze something, that video gets sent to Meta’s servers, then routed to Sama, a subcontractor in Nairobi, Kenya. Workers there manually label objects in your footage. They see everything you recorded, intentionally or not. 7 million pairs sold in 2025 alone. Every single pair generates training data that flows through human eyes in Kenya. Workers told Swedish journalists they see people undressing, using bathrooms, having sex, and accidentally filming bank card details. One worker said “we see everything, from living rooms to naked bodies.” Meta’s automatic face anonymization is supposed to protect people in the footage. Workers say it fails in certain lighting. Faces that should be blurred are sometimes fully visible. The person you recorded without knowing? A stranger in Nairobi can identify them. Buried in Meta’s terms of service is one sentence doing enormous legal work: the company reserves the right to conduct “manual (human) review” of your AI interactions. That’s the legal cover for routing intimate footage from Western homes to a $2/hour labor force operating under NDAs, office surveillance cameras, and a strict no-questions policy. Workers say if you raise concerns about what you’re seeing, you’re fired. This is the same company, Sama, that TIME exposed in 2023 for paying Kenyan workers $2/hour to label graphic content for OpenAI while being billed at $12.50/hour per worker. Workers described the experience as torture. Sama ended that contract, then pivoted to labeling Meta’s glasses footage. Same workforce. Same rates. Meta markets these glasses as “designed with your privacy in mind.” The privacy design is a tiny LED light on the frame that most people don’t notice. The data pipeline behind it routes your bedroom footage to a contractor with a documented history of worker exploitation, failed anonymization, and union-busting lawsuits. And the next generation of these glasses? Meta is planning to add facial recognition. The same system that can’t reliably blur faces in training data wants to start identifying them on purpose. The LED light on the frame is doing about as much for your privacy as the terms of service nobody reads.

This secret #iPhone gesture will come in handy…

A student built a real anti-gravity machine… using an Arduino. How to Make an Acoustic Levitator: Arduino Nano + motor driver + about 60 ultrasonic transducers. They all emit ~40 kHz sound. The sound waves meet and form fixed pockets in the air. Tiny bits of styrofoam get stuck in those pockets and just hang there. If you put your hand in, the pattern breaks and they fall. Same principle labs use to move droplets or samples without touching them.
