Federal, transportation and union leaders gathered in Las Vegas Monday to drive spikes into a symbolic rail, marking the beginning of construction for a $12 billion high-speed rail line that will link Las Vegas and the Los Angeles area.

“People have been dreaming of high-speed rail in America for decades,” Transportation Secretary Pete Buttigieg said Monday ahead of the groundbreaking ceremony. “It’s really happening this time.”

Among the myriad of projects that challenge traditional norms and offer innovative approaches to gaming and game development, hand gesture-based systems undeniably stand in a league of their own, a fact that’s recently been reaffirmed by Programmer and ML enthusiast Ayaan Khan.

Over on LinkedIn, Ayaan presented an impressive setup he devised during his high school years that enables one to play racing games by simply waving fingers in the air and making different hand gestures in front of a webcam. Inspired by the idea of combining technology with gaming, the system allows users to steer virtual cars by detecting which fingers are displayed to the camera, offering a truly unique gaming experience.

In the demo shared by Ayaan, he showed how the system can be utilized to play EA’s 2017 racing game, Need for Speed Payback. While the developer refrained from revealing the inner workings of his system, he hinted that it relies primarily on Python, OpenCV, and MediaPipe, providing a clue for aspiring developers interested in replicating the setup.

In a recent interview, NVIDIA CEO Jensen Huang shared his vision for the future, predicting that humanoid robots will soon become mainstream products, revolutionizing various industries.

Huang emphasized that manufacturing costs for humanoid robots will be surprisingly low, comparable to the price range of cheap cars. He proposed a price range of $10,000 to $20,000 for these robots, making them accessible to a wide range of consumers.

Drawing parallels with the automotive industry, Huang highlighted the potential flexibility and versatility of robots in certain man-made environments. He suggested that these robots could handle dangerous, repetitive, or tedious tasks, enhancing efficiency and safety in workplaces.

Humanoid robots have been in development for many years by Japan’s Honda and Hyundai Motor’s Boston Dynamics. Earlier this year, Microsoft and Nvidia-backed startup Figure said it had signed a partnership with German automaker BMW to deploy humanoid robots in the car maker’s facility in the US.

Elon Musk said before that robot sales could become a larger part of the Tesla business. He said, “I think Tesla is best positioned of any humanoid robot maker to be able to reach volume production with efficient inference on the robot itself.”

To save on fuel and reduce aircraft emissions, engineers are looking to build lighter, stronger airplanes out of advanced composites. These engineered materials are made from high-performance fibers that are embedded in polymer sheets. The sheets can be stacked and pressed into one multilayered material and made into extremely lightweight and durable structures.

Tesla has leaked some details about its elusive new Model 3 Performance ‘Ludicrous’, which is expected to launch any day.

The new Model 3 Performance, which could be named ‘Ludicrous’ based on the badges seen on some prototypes, has been expected to launch any day for over a month.

It was confirmed that the automaker was planning a new performance version of the Model 3 Highland with new badges showing up in the updated Tesla parts catalog.
