Original notes and practical guides about software architecture, systems, networking, virtualization, and product engineering.
MAME 2003-Plus is not a standalone MAME release. It is a libretro arcade emulator core that runs inside a libretro frontend, most commonly RetroArch. The libretro documentation describes MAME 2003-Plus as a multi-arcade system emulator core focused on frontend integration, performance, and broad compatibility. It was forked from MAME 2003, which came from Xmame 0.78, while MAME 2003-Plus continues to receive maintenance and added game support.
Hypervisor Fundamentals in SDV Context Popek/Goldberg Theorem A well-designed hypervisor is expected to satisfy the following three key criteria: itemize Equivalence Software running inside a Virtual Machine (VM) should behave identically to how it would run on physical hardware. The
Introduction Recent advances in AI are moving beyond perception-driven systems toward Physical AI , where models understand, predict, and interact with the physical world. This paradigm integrates perception, reasoning, modeling, and action into a unified framework. This document summarizes: itemize
This document is a practical development guide for building two Android Automotive OS (AAOS) native services that communicate over SOME/IP. It is intentionally product-neutral. Instead of describing a specific product, it explains a reusable pattern in which one native service
Facade 패턴은 복잡한 하위 시스템을 단순한 진입점 하나로 감싸서, 호출자에게 필요한 모델만 노출하는 구조다. Android Automotive OS(AAOS)는 이 패턴을 실제로 광범위하게 사용한다. 대표적인 예가 android.car.Car이며, 앱은 이 객체 하나를 통해 오디오, 전원, 사용자, 차량 속성 등 여러 자동차 기능에 접근한다. 이 문서는 Facade 패턴을 실제 서비스 설계에 적용하는 방법을 정리하고, AAOS의 Car.java -> CarPropertyManager -> ICarImpl -> CarPropertyService -> VHAL 흐름을 구체적 사례로 설명한다.
In this paper, we are going to learn how to setup a vm instance using the QEMU. Based on a single OS (ubuntu) image, multiple virtual machine with their own identification will be run simultaneously. Like AWS and GCloud, we can setup instances to build up the cloud infra.
This part does not aim to explain a basic theory of computer networking but try to explain what we were missed since starting work from a company.
This document explains how to detect a new client connection of the dnsmasq
