The article discusses the Arma Micro Computer from 1962, which predates common references to the first microcomputer. This 20-pound, transistorized computer was designed for aerospace applications, including navigation and engine control. Despite its advanced features for the time, like a 22-bit serial architecture and a small instruction set with complex operations, it does not meet modern definitions of a microcomputer due to its use of discrete components. The computer used unique storage called transfluxors for non-destructive readouts, contributing to its reliability in aerospace environments....

The “Exploring Binary” website covers a wide range of topics related to binary numbers, including their properties, arithmetic operations (addition, subtraction, multiplication, division), and peculiarities like bicimals (binary decimals) and binary palindromes. It also delves into visualizations of binary numbers, conversions between decimal and floating-point binary numbers, and the mathematical foundations underlying these conversions. Additionally, the site explores the length of numbers in decimal versus binary formats and features articles on correctly rounding during conversions....

The website provides a collection of interactive widgets designed to illustrate key concepts in statistics and signal processing. Tools include visualizations on Bayes Theorem, Gaussian estimation, binary hypothesis testing, function application to random variables, Fourier transforms, signal transformation, and quantization, among others. Additionally, it offers educational tools on topics like graph algorithms, lambda calculus, logic expressions, and more, aimed at deepening understanding in computer science and mathematics. For further details, please visit the website....

Fabien Sanglard’s website is a personal space where he shares his coding projects and ideas developed outside of his professional work. The site hosts a wide range of articles that span topics from detailed technical reviews and programming insights to personal observations on hardware and software development. Articles cover a variety of subjects including game development, computer history, and specific technologies like Apple’s Pro Display XDR, mDNS, and adaptive tile scrolling techniques....

Water surface shader for 2D Pixel art games The text provides a detailed tutorial on recreating the water reflection effect seen in the game “Potions,” using the Love2D game framework and Lua scripting language. The author starts by expressing admiration for the game’s real-time reflections and wavy distortions in water, which inspired them to attempt a similar effect. They walk through the process step by step, beginning with project setup, including using hand-drawn sprites and setting up the main game environment with tiles for ground and water....
