In the history of galactic civilizations and mathematical education, there are three distinct phases: Survival, Inquiry, and Sophistication. The transition from informal intuition to rigorous formalism can be challenging but crucial for avoiding errors and misconceptions. The balance between intuition and formalism is essential in tackling complex mathematical problems. The goal is to have both […]
Summary: In 2019, the previously unremarkable galaxy SDSS1335+0728 suddenly began to shine brighter than ever before, leading astronomers to investigate the cause. Using data from various observatories including the Very Large Telescope (VLT) of the European Southern Observatory (ESO), they tracked the galaxy’s brightness fluctuations. Their study, published in Astronomy & Astrophysics, reveals unprecedented changes […]
Author finds an Agilent 2000a / 3000a Oscilloscope in rough shape on an online auction site. The scope doesn’t boot due to possible power supply failure or NAND corruption. Author purchases the scope for $220. Scope is disassembled and repairs begin. Author discovers a damaged encoder and a TSOP48 NAND memory package that may be […]
The author accidentally discovered a fractal-like structure while experimenting with the divisibility of complex numbers. The image generated resembles galaxies when viewed through Google image search. The algorithm used involves calculating the percentage of gaussian integers that result from a complex number division. The post generated significant interest and sparked debates on various platforms about […]
Error correcting codes are essential in various modern technologies like mobile phones, hard drives, and barcodes. Reed-Solomon error correction is a widely-used code due to its efficiency and availability. Despite their hidden presence, these codes play a crucial role in ensuring reliable communication and data storage. By structuring data into a reduced dictionary, error correction […]
The authors present a novel approach to 3D Gaussian Splatting by viewing the set of Gaussians as a random sample from an underlying probability distribution, akin to Markov Chain Monte Carlo samples. By introducing noise and utilizing Stochastic Gradient Langevin Dynamics, they eliminate the need for carefully engineered cloning and splitting strategies. The method provides […]
Serialization is crucial in game development, but can be tricky to implement effectively. Overcoming challenges like outdated save files and hierarchical state machines is key. I’ve spent 6 months developing new packages to streamline serialization. AOT-friendly serialization is important, and the new Introspection generator simplifies the process by automatically generating metadata about types. Our Serialization […]
Understanding ice nucleation is essential in predicting weather patterns. Lowering the energy barrier for nucleation can lead to ice formation at higher temperatures. Surfaces with the right structure facilitate water molecules in arranging themselves into a crystal. Researchers have discovered that certain bacteria and fungi proteins are excellent at ice nucleation and are even used […]
The author explores high-speed inter-process communication (IPC) in Rust, focusing on sending messages between processes executing on the same machine. The goal is to time how long it takes to send a message (“ping”) from one process and receive an acknowledgement (“pong”) from the other. Different communication approaches, like pipes, TCP, UDP, and shared memory, […]
