Windows 95 in Electron
Windows 95 in Electron. Runs on macOS, Linux, and Windows
windows95 in Electron is a quirky, nostalgia-driven project that ports a complete emulation of Microsoft Windows 95 into a desktop application that runs on modern operating systems like Windows, macOS, and Linux. It essentially wraps an emulator — preconfigured to boot Windows 95 — inside a user-friendly app built with web technologies so developers and hobbyists can explore the look and feel of that classic OS without needing legacy hardware or complicated setup. Users can interact with familiar UI elements like the Start menu, File Explorer, and retro applications in a sandboxed environment that evokes early personal computing. Beyond being a playful trip down memory lane, the project demonstrates how emulation can be packaged using modern frameworks & how legacy operating systems can be encapsulated as distributable desktop experiences. It’s become an example of how software preservation and creative programming can intersect, inspiring others to bring historic systems to life. -

SockJS-client
WebSocket emulation and Javascript client
SockJS is a browser JavaScript library that provides a WebSocket-like object. SockJS gives you a coherent, cross-browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between the browser and the web server. Under the hood SockJS tries to use native WebSockets first. If that fails it can use a variety of browser-specific transport protocols and presents them through WebSocket-like abstractions. SockJS is intended to work for all modern browsers and in environments which don't support the WebSocket protocol, for example, behind restrictive corporate proxies. SockJS-client does require a server counterpart, such as SockJS-node, which is a SockJS server for Node.js. The API should follow HTML5 Websockets API as closely as possible. All the transports must support cross domain connections out of the box. It's possible and recommended to host a SockJS server on a different server than your main web site. -

Serverless Offline
Emulate AWS λ and API Gateway locally
This Serverless plugin emulates AWS λ and API Gateway on your local machine to speed up your development cycles. To do so, it starts an HTTP server that handles the request's lifecycle like APIG does and invokes your handlers. Options passed on the command line override YAML options. List of available function names and their corresponding serverless.yml function keys are listed after the server starts. This is important if you use a custom naming scheme for your functions as serverless-offline will use your custom name. The left side is the function's key in your serverless.yml and the right side is the function name that is used to call the function externally such as aws-sdk. Once you run a function that boots up the Docker container, it'll look through the layers for that function, download them in order to your layers folder, and save a hash of your layers so it can be re-used in future. -

Simple 8-bit Assembler Simulator
Simple 8-bit Assembler Simulator with Angular.js
A simulator that provides a simplified assembler syntax (based on NASM) and is simulating an x86-like CPU. Press Help inside the simulator to see an overview of the supported instructions. Make sure you have Grunt installed to compile the asmsimulator.js script. Run grunt to build the project. The simulator is written in JavaScript with Angular and runs on every device with a web browser. It has a lot of simplifications and constraints, but it is the basic structure of every emulator. The console output uses memory mapping and maps a specific portion of the memory to the console. Thus writing to the console output is as simple as writing into a specific memory location. The CPU reads instructions from the memory and executes them. The memory contains our program code and can be used by the program to store data. -

Turns the BeagleBone Black into a Nintendo-based retrogaming console.
The Beagle Entertainment System (BES) project is a complete filesystem image that turns the ARM-based BeagleBone Black single board computer into an embedded appliance capable of playing software for the SNES, NES, GBA, and Gameboy Color platforms. A full system image, ready to be written to a microSD card and used as-is, is available for download. Just connect your BES-enabled BeagleBone Black to your network and you can use BES's Node.js web interface to add or remove ROMs, configure gamepads, and edit ROM descriptions for the front-end GUI. There's no need to hand edit configuration files or manually copy ROM files onto the microSD card!
