In this tiny ebook, the author provides a beginner’s guide to writing 6502 assembly language, a language that powered famous computers in the past. Despite being considered a dead language, modern hobbyists still use 6502 processors. The author argues that learning 6502 assembly language is valuable for understanding the lowest level of computer abstraction. Through […]
The author shares how they have collaborated with AI educators to customize AI by Hand exercises, which are being used worldwide. Despite occasional errors in the solutions, students catching them shows they are engaged. The author is now working on a tool to allow others to create their own AI exercises using Google Sheets to […]
The author introduces an experimental concurrent programming language called Par, designed to bring the power of linear logic into practical programming. The language operates on channels that represent values and processes, ensuring no deadlocks with dynamic typing. Features like channel spawning, closing channels, signaling, and combining operations are highlighted, showcasing the expressive concurrency of Par. […]
Pre-trained large language models (LLMs) can efficiently compute basic arithmetic like addition by using Fourier features as dimensions in the hidden state. This innovative approach shows that MLP and attention layers in the model use Fourier features in a complementary manner to approximate magnitude and perform modular addition, respectively. Pre-training is essential for this mechanism, […]
The article discusses the complex relationship between electric and magnetic fields in electronic circuits, challenging the traditional hydraulic analogy. The author delves into the concept of relativistic length contraction to explain the behavior of electrons in motion and the origin of magnetic fields. The article also touches on the implications of special relativity and the […]
Researchers in Beijing have developed a safer, more sustainable alternative to lithium-ion batteries using aluminum. The new aluminum-ion battery design boasts an extremely long lifespan, retaining 99% of its capacity after 10,000 charge/discharge cycles compared to 80% for typical Li-ion batteries. The solid-state electrolyte makes the battery safer and leak-proof, even in extreme conditions like […]
This web content demonstrates how to create animations using GPU shaders and signed distance fields without images or libraries, as shown with Pixel Rick. The code, written in OpenGL Shading Language, determines the color of each pixel in the preview screen. Various shapes can be drawn using different functions, such as circle, star, and round_rect. […]
