The article details the history of the TRS-80 Model I computer, highlighting its cost-cutting design, limitations, and impact on the early home computer market. It discusses its hardware, software (Level I & II BASIC, CP/M compatibility), and eventual replacement by the Model II and Model III. It also touches on the community's nickname 'Trash-80' and its lasting legacy.
This article discusses Fibonacci hashing, a method using the golden ratio to map data locations, potentially offering faster lookup speeds and more even distribution compared to integer modulo hashing. However, it may be problematic with data containing many Fibonacci numbers and is not a cryptographic hash.
This article details a workaround for a memory leak in Autokey on Linux, specifically addressing issues arising from the transition away from X11 and toward Wayland. The author implemented a wrapper script to monitor Autokey's memory usage and restart it when it exceeds a defined threshold.
WattWise is a command-line interface (CLI) for power monitoring smart plugs. It can track power consumption and throttle CPU usage based on electricity prices. It supports TP-Link plugs directly and integrates with Home Assistant.
This article details a DIY atomic force microscope built from mostly junk parts. It utilizes a laser-based deflection reading system instead of traditional piezo motors, achieving 35-um resolution with readily available materials. The project focuses on simplicity and cost-effectiveness, making it suitable for educational purposes.
The article describes a project where someone developed a software-defined GPS receiver from scratch using Python and an RTL-SDR dongle. The project tackles the 'coarse' positioning capability of GPS, achieving location resolution within 24 seconds from a cold start. The article highlights the project's accessibility and potential as a starting point for further exploration of GPS technology.
The article discusses the challenges faced by hobbyists when building antennas like Yagi and WiFi cantennas, emphasizing the importance of antenna size and tuning to the target frequency for optimal signal performance. It references a webinar by Dr. Jonathan Chisum, highlighting the practical insights beyond textbook theory that can improve antenna design.
A 6502 system emulated in a busybox ash shell script, featuring RAM, ROM, and an emulated serial port on STDIO, with built-in monitor and debugger.
A modern replica of the 1955 Elektronensaldierer ES 24, built by Heinz Nixdorf, is on display in the HNF computer museum. The replica features 204 vacuum tubes and a USB interface for modern communication, making it a fascinating blend of old and new technology.
A guide on using large language models (LLMs) for programming tasks, including examples, strategies, and useful tips for effectively using AI assistants like ChatGPT and Claude.
