🚨Google built an invisible watermark into every image Gemini has ever generated. Over 10 billion pieces of content marked. One unemployed engineer just cracked it open. With 200 black images and math. It's called reverse-SynthID. SynthID is Google DeepMind's invisible watermark. It's embedded at the pixel level into every image, video, audio, and text generated by Gemini. Invisible to the human eye. Designed to survive cropping, compression, screenshots, and format changes. It was supposed to be unbreakable. Here's how he broke it: → Generated 200 pure black and pure white images from Gemini → When you average enough pure-black AI images, every non-zero pixel IS the watermark. Nothing to hide behind. Just the signal, naked. → Used FFT spectral analysis to map the exact carrier frequencies → Discovered the watermark uses a fixed phase template — identical across every image from the same model → Cross-image phase coherence at carrier frequencies: over 99.5% → Built a detector that identifies SynthID watermarks with 90% accuracy → Built a V3 bypass that drops 91% of the phase coherence and 75% of carrier energy — at 43+ dB PSNR. Almost zero visible quality loss. No neural networks. No proprietary access. No leaked code. Just signal processing and too much free time. Here's the wildest part: The green channel carries the strongest watermark signal. The carrier frequencies change based on image resolution. And the entire phase template is fixed — meaning every single Gemini image carries the same fingerprint structure. One engineer. 200 black images. A Fourier transform. That's all it took to reverse-engineer a system protecting 10 billion+ pieces of content. 519 GitHub stars. 39 forks. Python. Research and educational purposes only. 100% Open Source.

Hello, Moon. It’s great to be back. Here’s a taste of what the Artemis II astronauts photographed during their flight around the Moon. Check out more photos from the mission: nasa.gov/artemis-ii-mul…

That's us! 🌍 The Artemis II crew captured beautiful, high-resolution images of our home planet during their journey to the Moon. As @Astro_Christina put it: "You guys look great."

Why are there no green stars? As they burn hotter, stars shift: red → orange → yellow → white → blue... But green? Never! This stunning animation shows the blackbody physics trick; our eyes see white when the peak hits green.

Liftoff. The Artemis II mission launched from @NASAKennedy at 6:35pm ET (2235 UTC), propelling four astronauts on a journey around the Moon. Artemis II will pave the way for future Moon landings, as well as the next giant leap — astronauts on Mars.

Introducing Operation Matrix Because Matrix operations generally break kids’ brains on whiteboards… Matrices aren't just numbers- they are transformations in space Now can actually SEE the geometry: every addition, multiplication, inverse, eigenvalue, and eigenvector becomes a transformation in real-time space. What it visualizes: • Basic ops (add/subtract/multiply) • Transpose, Invert, Adjugated • Cross products + Determinant • Matrix powers + Eigenvalues/Eigenvectors #LinearAlgebra #CreativeCoding #ThreeJS #ReactThreeFiber #MathVisualization #EdTech #WebGL #STEM @reactthreefiber @threejs

Someone built a Chromium browser that runs entirely in your terminal. It's called Carbonyl, and it renders actual web pages in your command line. The best part is it runs with 0% CPU usage when idle. - Full Chromium engine in the terminal. - dles at exactly 0% CPU. - Fast, lightweight, and completely terminal-native. 100% Open Source.
