“We must confess that we are the possible.”
On Christmas Eve, actor Vanessa Redgrave read from Maya Angelou’s poem “A Brave and Startling Truth.” Redgrave is a longtime human rights activist, speaking out on issues like Vietnam, the Iraq War and Palestine.
On Dec. 31, at the direction of @SecWar Pete Hegseth, Joint Task Force Southern Spear conducted a lethal kinetic strike on two vessels operated by Designated Terrorist Organizations. Intelligence confirmed the vessels were transiting along known narco-trafficking routes and engaged in narco-trafficking. A total of five narco-terrorists were killed during these actions - three in the first vessel and two in the second. @DeptofWar #OpSouthernSpear

URP particle-based screen distortion. 🖥️
Particles are in the 3D world, but use screen coordinates to distort what's behind them. Excellent for shockwaves! ⭕️
A bit more work + polish, and I can throw the shader on GitHub.

Harvard's just open-sourced their ML Systems textbook. it's extremely practical for not just learning how to build and train models, but to build production systems (the skill that actually matters). topics are cool af:
> building autograd, optimizers, attention, and a mini-pytorch from scratch to truly learn how an ML framework runs. (i love this the most)
> basics of DL, batch sizes, precision, model architectures, and training
> ML performance optimization, HW acceleration, benchmarking, efficiency
so this is not just an intro to machine learning, it's the full package from the beginning to the actual end. right now you can read the book and access the code for free. this is one of the best books I've seen dropping in 2025, so don't sleep on it.
here's the repo (you can find the book link there): https://t.co/5OEWPBNaJp
🛜 No cameras needed for motion detection! 👻
This open-source project called ESPectre lets you detect movement using just Wi-Fi signals!
All you need:
✅ $10 ESP32 device
✅ 15 minutes to set up
✅ Zero programming skills
Works through walls, integrates with Home Assistant, and respects your privacy - no cameras or mics!
Check out the GitHub link: https://t.co/EcvzV5Yt7t

From real-world engineering to 3D. 🤖 I modeled and animated my own omnidirectional Rollbot in C4D. The inspiration comes directly from @XRobotsUK
A short loop, but a great rigging challenge! #Robotics is always a source of #3D art. What other #robot should I try modeling?
#AI
Some of the smartest engineering ideas come from tradition:
The Twisted Chrysanthemum Joint shows how precision alone can hold wood together tightly.
No nails, no glue, just skill.
A reminder that true craftsmanship often solves problems we still face today.
Why it matters
✅ Holds complex structures with pure geometric fit
✅ Needs extreme accuracy and perfect cuts
✅ Built to last without extra fasteners
✅ Inspires modern engineering and robotics for friction-based connections
Sometimes old techniques offer better lessons than new ones.
I could watch those videos for hours 🤓

This is one of the more unusual flying robots I have seen.
Researchers at the University of Tokyo built DRAGON, a transformable aerial robot that can change its shape while flying.
Instead of a rigid frame, it is made of four linked segments.
Each segment has two ducted rotors mounted on gimbals, so every link can redirect thrust independently.
• The robot controls its full pose in SE(3) while reshaping mid-air
• It can form different geometries to stabilize itself or interact with objects
• The navigation stack computes the most efficient shape for the current task
• It lifts over 3 kg, which is unusually high for this class of system
This effectively turns a drone into a flying manipulator. Not a gripper bolted on top, but the airframe itself becomes the manipulator.
The authors also mention an interesting idea for range extension: letting the robot walk on the ground when flying is not required.

Human to robot interaction, without buttons or code.
This gesture-controlled mecanum car shows how little it can take to make machines feel intuitive.
• Driven purely by hand gestures
• Omni-directional motion with mecanum wheels
• Body design that adapts to movement
It is a toy demo, but the pattern is serious.
Natural input plus mobile robotics removes friction from how we control machines.
Imagine this logic on factory carts, inspection robots, or material handling systems.
