🧠 American math genius checked out the latest OpenAI's language model Terence Tao is widely regarded as a math genius. He scored a 760 on the SAT math section at age 8, and became the youngest gold medalist in the International Mathematical Olympiad at age 13. Tao earned his PhD from Princeton at just 20. Recently on Mastodon he shared his experience with OpenAI's GPT-o1 model, noting its advancements in handling mathematical tasks. In his experiments, the model successfully identified and applied Cramer's theorem, showing clear improvement over past versions. However, when tackling more complex problems, it still needed guidance, resembling the work of a capable but inexperienced graduate student. Tao believes that with further development and integration of tools like computer algebra systems, AI could soon assist in advanced research. While current models require effort to prompt and verify, he sees potential for broader use in mathematics as they continue to improve. ⛓ More information... #news #artificial_intelligence

📺 Raspberry Pi Pico RP2350 - Massive Performance Boost Trick This video explores the performance differences between Cortex-M33 and RISC-V Hazard 3 cores on the 🍓 RP 2350 microcontroller. Initially, the RISC-V cores were surprisingly slower than expected due to using suboptimal compiler setups on Windows with 👩‍💻 Visual Studio Code. Feedback from the core designer revealed that the default toolchains lacked important optimizations, especially for floating-point operations. By switching to 👩‍💻 Linux and manually configuring the toolchain and compilers, significant performance improvements were achieved. The optimized setup showed the RISC-V cores outperforming Cortex-M0 cores and, in some cases, even matching or exceeding the Cortex-M33. The video concludes that to fully unlock the RP 2350's potential, developers should use the right compiler and setup, ideally on Linux, for the best performance. ⛓ https://youtu.be/_O3Aeyv2ILM #video #raspberry #pico2

🤖 Reconfigurable Continuous Track Robot (RCTR) The RCTR introduces a new approach to robotic mobility by reconfiguring its shape dynamically as it moves. It can lock individual track links at different angles, enabling it to climb steps, bridge gaps, and adapt to various terrains. A small actuator at the front locks the links, while a mechanism at the back resets them, allowing the robot to switch between flexible and rigid states. Although the RCTR currently lacks steering, adding this capability would be straightforward. Its design showcases a unique ability to handle diverse environments, making it adaptable for a wide range of applications. ⛓ More information... #robots

📺 Flexduino: Creating a Flexible Arduino UNO Clone This video describes a unique ♾ Arduino UNO clone, featuring a flexible PCB substrate instead of traditional rigid materials. While it sacrifices some functionalities like a ground plane due to its flexible nature, it serves as both a practical tool and a demonstration of cutting-edge electronic design. ⛓ https://youtu.be/S9VHnmVI19w #video #arduino

✈️ On recent events You might already know about the Telegram's CEO arrest in France. Without a doubt, its bad news for all of us. When I was a teenager, I remember so well all of my peers using 🌐 VK.com, a social network widely popular in post-soviet countries that was founded by Durov. I never really liked it but I also remember the efforts Russian government put into seizing control over it. Many years passed since then and I'm living in Europe for quite a while now but the recent events gave me a strong feeling of déjà vu. Durov is locked for good and we both know what's the only way out. With that said, I strongly recommend to everybody to get rid of the sensitive information saved on Telegram's servers. Whether we want it or not, the Telegram is going to be as regulated as any other platform out there.
