    GraphQL Java Tools

    GraphQL Java Tools

    A schema-first tool for graphql-java inspired by graphql-tools for JS

    This library allows you to use the GraphQL schema language to build your graphql-java schema. Inspired by graphql-tools, it parses the given GraphQL schema and allows you to BYOO (bring your own object) to fill in the implementations. GraphQL Java Tools works extremely well if you already have domain POJOs that hold your data (e.g. for RPC, ORM, REST, etc) by allowing you to map these magically to GraphQL objects. GraphQL Java Tools aims for seamless integration with Java, but works for any...

    Svix

    Svix

    The enterprise-ready webhooks service

    ...Webhooks require a lot more engineering time, resources and ongoing maintenance than you would first expect. Building a secure, reliable, and scalable webhook service is hard and time-consuming. We built it so you can focus on what matters most, your business. Customer endpoints fail or hang more often than you think. You need automatic retries to ensure deliverability. You need to monitor the deliverability of your webhooks to different endpoints, disable failing ones and notify your customers. Webhooks come with a myriad of security implications, such as SSRF, replay attacks and unauthenticated webhook events. ...

    Driver.js

    Driver.js

    A lightweight, dependency-free JavaScript library

    ...It strives to be unobtrusive: tours can be triggered contextually, resumed, or dismissed without hijacking the app. Accessibility and keyboard interaction are considered so tours remain usable beyond simple mouse clicks. Because it has no hard dependency on a specific framework, it integrates into vanilla JS apps or modern stacks alike.

    Proxy

    Proxy

    Proxy: Next Generation Polymorphism in C++

    For decades, object-based virtual tables have been a de facto implementation of runtime polymorphism in many (compiled) programming languages. There are many drawbacks in this mechanism, including life management (because each object may have a different size and ownership) and reflection (because it is hard to balance between usability and memory allocation). To workaround these drawbacks, some languages like Java or C# choose to sacrifice performance by introducing GC to facilitate lifetime management, and JIT-compile the source code at runtime to generate full metadata. We improved the theory and implemented it as a C++ library without sacrificing performance, proposing to merge it into the C++ standard.

    ...All without being a monitoring expert. Everybody starts monitoring with logs because they are there by default. Just connect to your server and start tailing. But logs have a hard time showing you the overall response times for your application, or whether certain calls to the database are happening in sequence or parallel (among a million other things).

    Slug Generator Library

    Slug Generator Library

    Slug Generator Library for PHP, based on Unicode’s CLDR data

    ...There are many code snippets and some good libraries out there that create slugs, but I didn’t find anything that met my requirements. Options are often very limited which makes it hard to customize for different use cases. Some libs carry large rulesets with them that try to convert characters to ASCII, no one uses Unicode’s CLDR which is the standard for transliteration rules and many other transforms.

    libpku is a community-driven repository that collects and organizes university course materials, lecture notes, past exams, problem sets, and student-compiled summaries—primarily for Peking University, but also including contributions from other institutions. Its mission is to make hard-to-find, experience-based educational content more openly accessible, so that students don’t have to reinvent what prior generations of learners already collected. The repository is organized into folders by course or subject, where contributors upload PDFs, slides, summaries, and guides (subject to copyright constraints). The project provides a web interface (via a GitHub Pages site) where users can browse and download specific materials conveniently. ...

    Normalize.css

    A modern alternative to CSS resets

    normalize.css is a small CSS file that provides a consistent baseline of default styles across browsers without erasing useful browser opinions. Rather than a “hard reset” that zeroes everything, it preserves sensible defaults for elements while fixing inconsistencies and edge cases that vary between engines. The project documents why each rule exists, targeting real-world quirks such as form control alignment, typographic defaults, and HTML5 element rendering. It is deliberately minimal and stable, making it a safe foundation for both custom design systems and heavyweight frameworks. ...

    HexMUD

    A generic C++ MUD server featuring a strategy-style hexagon map

    ...While not specifically a MUD project, this project's basic concept has merged into another that can be found here: https://github.com/nicrohobak/Toolbox Along with an additional, related project of extreme interest: https://github.com/nicrohobak/AnsiGL ------------------------------------------------------------ HexMUD aims to be a fully-featured, game-system agnostic MUD server with a centrally focused feature of an added top-down hexagon-based map (dynamically generated and drawn in ANSI/ASCII art) giving a basic visual representation of your immediate surroundings in addition to traditional descriptions. Many (most?) MUD servers hard-code a specific game system, or a specific game setting within their code, but HexMUD strives to be as generic as possible in this area, allowing each separate administrator to easily build a custom code base while also gaining access to all of the core features HexMUD provides.
