    Finagle

    Finagle

    A fault tolerant, protocol-agnostic RPC system

    Finagle is an extensible RPC system for the JVM, used to construct high-concurrency servers. Finagle implements uniform client and server APIs for several protocols, and is designed for high performance and concurrency. Most of Finagle’s code is protocol agnostic, simplifying the implementation of new protocols. Finagle is written in Scala, but provides both Scala and Java idiomatic APIs. Finagle is a protocol-agnostic, asynchronous RPC system for the JVM that makes it easy to build robust clients and servers in Java, Scala, or any JVM-hosted language. We set out to develop a single implementation of the basic components of network servers and clients that could be used for all of our protocols. Finagle is a protocol-agnostic, asynchronous Remote Procedure Call (RPC) system for the Java Virtual Machine (JVM) that makes it easy to build robust clients and servers in Java, Scala, or any JVM-hosted language.

    Jupyter Enterprise Gateway

    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.

    Amazon DynamoDB Session Store

    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.

    Laravel Cookie Consent

    Laravel Cookie Consent

    Make your Laravel app comply with the crazy EU cookie law

    All sites owned by EU citizens or targeted towards EU citizens must comply to a crazy EU law. This law requires a dialog to be displayed to inform the users of your websites how cookies are being used. You can read more info on the legislation on the site of the European Commission. The newest Laravel package made by my colleagues at Spatie and myself makes your app compliant with that law. When the user clicks "Allow cookies" a laravel_cookie_consent cookie will be set and the dialog will be removed from the DOM. On the next request Laravel will notice that the laravel_cookie_consent has been set and will not display the dialog again. The legislation is pretty very vague on how to display the warning, which texts are necessary, and what options you need to provide. This package will go a long way towards compliance, but if you want to be 100% sure that your website is ok, you should consult a legal expert.

    Headless Chromium-based web performance metrics collector

    Headless Chromium-based modular web performance metrics collector. Modular approach, each metric is generated by a separate "module". phantomas "core" acts as an events emitter that each module can hook into. In-depth metrics such as: number of events bound via jQuery, calls to window.writeor complex and duplicated CSS selectors (via analyze-css). JSON as an output format. Easy integration with other nodejs projects via CommonJS module (see API docs). Metrics can be emitted from the JavaScript code of the page phantomas is run against (thanks to helper functions available in window.__phantomas). Device profiles allow phantomas to emulate mobile or tablet (by setting a proper user agent and viewport). phantomas comes as a CommonJS module that you can use in your nodejs projects. Use grunt to automate daily dev tasks, including your's application web performance.

    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.

    Java JWT

    Java JWT

    Java implementation of JSON Web Token (JWT)

    A Java implementation of JSON Web Token (JWT) - RFC 7519. This library requires Java 8 or higher. The last version that supported Java 7 was 3.11.0. The library implements JWT Verification and Signing using several algorithms. The Algorithm defines how a token is signed and verified. It can be instantiated with the raw value of the secret in the case of HMAC algorithms, or the key pairs or KeyProvider in the case of RSA and ECDSA algorithms. Once created, the instance is reusable for token signing and verification operations. When using RSA or ECDSA algorithms and you just need to sign JWTs you can avoid specifying a Public Key by passing a null value. The same can be done with the Private Key when you just need to verify JWTs.

    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.
