EdT365 Rust Playground vs Linear Algebra

EdT365 Rust Playground is a native editor for writing, compiling, and running Rust — right from your mobile devices. It talks to the public play.rust-lang.org API (or your own self-hosted instance). • Native editor with Tree-sitter Rust highlighting, line numbers, light/dark • A programming-keys row above the keyboard: { } ( ) [ ] ; : = -> => and more • Streaming run output over WebSocket — see compile progress live, cancel mid-run • Format (rustfmt) and Clippy, with inline error highlighting • Safari-style tabs, each keeping its own code and output • Learn: Quick Reference cheatsheet, 42 flashcards, 25 daily exercises • Embedded std docs, the interactive Rust Book, and roadmap.sh/rust • Files integration + a Share extension to open .rs from any app • Self-host support: point Settings at your own rust-playground server Made by Edtech365 Solutions Vietnam — Education • Development • Success.

MatrixViz makes linear algebra and computer graphics understandable by turning the maths into interactive visuals. Built for complete beginners, MatrixViz lets you drag vectors, reshape matrices, move cameras, adjust projections, and immediately see what each formula does. Every learning module connects a plain-language idea to a guided experiment, a live visual, the underlying equation, and a symbol-by-symbol explanation. LEARN LINEAR ALGEBRA VISUALLY • Explore vectors in 2D and 3D • Turn matrix columns into draggable handles • See rotation, scale, shear, reflection, and composition happen live • Understand determinants, inverse matrices, span, basis, and independence • Discover eigenvectors by finding the directions a transformation cannot turn UNDERSTAND COMPUTER GRAPHICS • Follow coordinates from object space to the screen • Inspect model, view, and projection matrices • Compare perspective and orthographic projection • Learn cameras, frustums, lighting, normals, depth, blending, winding, and culling • Experiment with Metal shader patterns using beginner-friendly visual controls LEARN BY DOING • Guided lessons paired with the real interactive modules • Always-visible formulas and plain-language symbol keys • Sliders and direct manipulation instead of code-first controls • Saved sandbox presets for returning to experiments • Adaptive layouts for iPhone, iPad, Mac, and Apple Vision Pro • Light and dark appearance options MATRIXVIZ PRO Optional MatrixViz Pro unlocks iCloud lesson-progress sync, educator presentation mode, and 1080p matrix-animation export across supported Apple platforms.
