iii
Effortlessly compose, extend, and observe every service
iii is a backend unification engine that organizes application behavior around a small set of primitives such as functions, triggers, and workers. It is designed to connect existing backend systems into a more inspectable and programmable runtime. The project includes a console for developers and operators to inspect functions, triggers, traces, and live state. Its goal is to reduce backend sprawl by giving teams a single operational layer for event-driven and function-based workflows. iii appears especially useful for teams that want clearer visibility into distributed backend behavior without replacing every existing component. Its main value is combining orchestration, observability, and operational control into a compact backend engine. -

Jupyter Enterprise Gateway
Enables Jupyter Notebooks to share resources across clusters
Jupyter Enterprise Gateway is a headless web server with a pluggable framework for anyone supporting multiple notebook users in a managed-cluster environment. Some of the core functionality it provides is better optimization of compute resources, improved multi-user support, and more granular security for your Jupyter notebook environment - making it suitable for enterprise, scientific, and academic implementations. From a technical perspective, Jupyter Enterprise Gateway is a web server that enables the ability to launch kernels on behalf of remote notebooks. This leads to better resource management, as the web server is no longer the single location for kernel activity. It essentially exposes a Kernel as a Service model. By default, the Jupyter framework runs kernels locally - potentially exhausting the server of resources. By leveraging the functionality of the underlying resource management applications like Hadoop YARN, Kubernetes, and others. -

CloudRetro
Web-based Cloud Gaming service for Retro Game
CloudRetro provides an open-source cloud gaming platform for retro games. It started as an experiment for testing cloud gaming performance with WebRTC and Libretro, and now it aims to deliver the most modern and convenient gaming experience through technology. Theoretically, in cloud gaming, games are run on remote servers and media are streamed to the player optimally to ensure the most comfortable user interaction. It opens the ability to play any retro games on a web-browser directly, which are fully compatible with multi-platform like Desktop, Android, IOS. In ideal network condition and less resource contention on servers, the game will run smoothly as in the video demo. Because I only hosted the platform on limited servers in US East, US West, Eu, Singapore, you may experience some latency issues + connection problem. You can try hosting the service following the instruction the next section to have a better sense of performance. -

Koa-OAI-Router
Koa Router, based on OpenAPI, Swagger and Json Schema
I have used Markdown and wiki to manage API doc, from which I have suffered a lot. It wastes too much time and is very boring. The document should be repaired when you change the API. It's very inconvenient to test and debug. The management of API doc totally depends on people. As a result, it is hard to make documents have high quality. Meanwhile, the developers will spend more time on testing, which may have a bad effect on the project. -

Omnom
A web content preservation service
Omnom is a self-hosted content preservation and web bookmarking platform that lets individuals and communities save and archive web content in a way that reflects exactly what they saw in their browser at the moment of capture. Unlike simple bookmark lists, Omnom makes full page snapshots — including dynamic content — so that saved pages remain viewable even if the original goes offline or changes later. It was built with a multi-user web interface and includes support for federated social protocols like ActivityPub, allowing integration with decentralized networks and community tools. The application lets users categorize, tag, and search saved content, aggregate RSS/Atom feeds, and review changes between captured snapshots with diff views. A browser extension for Chrome and Firefox makes it easy to add new bookmarks and initiate snapshots directly from your browsing session. -

Amazon DynamoDB Session Store
Handles sessions for Ruby web applications using DynamoDB as a backend
The Amazon DynamoDB Session Store handles sessions for Ruby web applications using a DynamoDB backend. The session store is compatible with all Rack-based frameworks. For Rails applications, use the aws-sdk-rails gem. The session store is a Rack Middleware, meaning that it will implement the Rack interface for dealing with HTTP request/responses. This session store uses a DynamoDB backend in order to provide scaling and centralized data benefits for session storage with more ease than other containers, like local servers or cookies. Once an application scales beyond a single web server, session data will need to be shared across the servers. DynamoDB takes care of this burden for you by scaling with your application. Cookie storage places all session data on the client side, discouraging sensitive data storage. It also forces strict data size limitations. DynamoDB takes care of these concerns by allowing for a safe and scalable storage container with a much larger data size limit. -

Amazon EKS Pod Identity Webhook
Amazon EKS Pod Identity Webhook
This webhook is for mutating pods that will require AWS IAM access. After version v0.3.0, --in-cluster=true no longer works and is deprecated. Please use --in-cluster=false and manage the cluster certificate with a cert-manager or some other external certificate provisioning system. This is because certificates using the legacy-unknown signer are no longer signed when using the v1 certificates API. Create an OIDC provider in IAM for your cluster. You can find the OIDC discovery endpoint by describing your EKS cluster. Create an IAM role for your pods and modify the trust policy to allow your pod's service account to use the role. All new pod pods launched using this Service Account will be modified to use IAM for pods. Below is an example pod spec with the environment variables and volume fields added by the webhook. To ensure workloads are scheduled on windows nodes have the right environment variables, they must have a nodeSelector targeting windows it must run on. -

Node.js Client for Google Maps Services
Node.js client library for Google Maps API Web Services
This library is designed for server-side Node.js applications. Attempting to use it client-side, in either the browser or any other environment like React Native, may in some cases work, but mostly will not. Please refrain from reporting issues with these environments when attempting to use them, since server-side Node.js applications is the only supported environment for this library. For other environments, try the Maps JavaScript API, which contains a comparable feature set, and is explicitly intended for use with client-side JavaScript. Authentication via client ID and URL signing secret is provided to support legacy applications that use the Google Maps Platform Premium Plan. The Google Maps Platform Premium Plan is no longer available for sign up or new customers. All new applications must use API keys. -
