mobile-mcp

mobile-next/mobile-mcp · ★ 9.7K

Mobile MCP is a Model Context Protocol server that lets AI agents automate and scrape native iOS and Android apps - on simulators, emulators, or real devices - through a single platform-agnostic set of tools.

breakscale

xevrion/breakscale · ★ 1.7K

Breakscale is a system design simulator where you place components on a canvas, wire them together, then drag a traffic slider and watch a real discrete-event simulation show latency, queues, and failures emerge, so you can learn how distributed systems behave under load.

cs249r_book

harvard-edge/cs249r_book · ★ 29.1K

An open textbook and full curriculum on Machine Learning Systems — AI engineering — from Harvard's CS249r course: four volumes covering foundations, scaling, agentic AI, and physical AI, plus labs, projects, and instructor materials.

hermes-gadget-sdk

Adolanium/hermes-gadget-sdk · ★ 407

Hermes Gadget SDK lets you build voice and text hardware devices (ESP32 boards, a Raspberry Pi Linux client, or a desktop simulator) that connect to your own Hermes Agent: hold a button, ask it something, and hear or see the reply.
