OSX Serial Generator
Generate complete sets of Serial Numbers for OSX-KVM, Docker-OSX
OSX Serial Generator is a shell-based toolkit for generating valid-looking macOS serial numbers, hardware UUIDs, and board serials for use in virtualized macOS environments such as OSX-KVM, Docker-OSX, and OpenCore-based Hackintosh setups. It is positioned for good-faith security and Apple bug bounty research, where having realistic device identifiers is necessary to reproduce issues or test services that validate Apple hardware details. The project provides scripts and configuration templates that automatically fill in placeholders like serial, board serial, UUID, ROM, and even display parameters inside plist files. This means researchers can bring up many different “machines” with distinct identities without manually hunting for serial ranges or crafting XML by hand. ... -

Google CTF
Google CTF
...It’s a learning and practice archive: competitors and educators can replay tasks across categories like pwn, reversing, crypto, web, sandboxing, and forensics. The code and binaries intentionally contain vulnerabilities—by design—so users can explore exploit chains and patching in realistic settings. The repo also includes infrastructure components and links to a scoreboard implementation, giving organizers reference material for hosting their own events. As a living archive, it documents changes in exploitation trends and defensive techniques year over year. Clear warnings advise against deploying challenge infrastructure in production due to purposeful insecurities. -

EpicReact.Dev
Build a ReactJS App workshop
...The project demonstrates how to structure a modern React app, including data modeling, authentication, routing, testing, and interaction with a backend. It uses a realistic “bookshelf” domain where users can manage lists of books, track reading status, and record notes, which provides a concrete context for learning. The repository includes setup scripts and system requirements checks for Git, Node, and npm, plus Docker and Codespaces options for people who struggle with local environments. A guided workflow, driven by a node go script and INSTRUCTIONS.md, lets learners move between exercises and extra credit steps while the repository updates the working files for each stage. ... -

Telepresence
Local development against a remote Kubernetes or OpenShift cluster
...With Telepresence, you can make changes to your service as if you're developing locally, without having to run all the dependencies on your local machine. You want to catch errors before they get shipped to production, but to do that you need a realistic development environment and with Kubernetes, those can be expensive. Telepresence lets you connect the copy of your service locally to your remote dependencies, so you can test like your laptop is in your cluster. -

Rust Latam
Learn to write Rust procedural macros
This is a workshop/repository by the Rust developer David Tolnay (dtolnay) intended to teach how to write Rust procedural macros (derive macros, function-like macros, attribute macros). The repo contains multiple toy/realistic macro projects drawn from real use-cases: e.g., derive(Builder), derive(CustomDebug), seq!, #[sorted], #[bitfield]. The README indicates the focus is on learning: parsing token streams, generating code, handling generics, attribute arguments, etc. It has test harness and workflow guidance. Because procedural macros are quite subtle in Rust, this workshop is a strong resource for anyone wanting to go from beginner to intermediate/advanced macro writing. -

RealWorld
Exemplary fullstack Medium.com clone powered by React, Angular, Node
RealWorld is the “mother of all demo apps”—a full spec and starter backend/frontend that implements a Medium-like blogging platform to showcase best practices across many frameworks. Instead of trivial todo lists, it provides a realistic feature set: authentication, CRUD operations, pagination, comments, profiles, tagging, and favoriting. The same spec is realized dozens of times (React, Vue, Svelte, Angular, Solid, Next, Remix, and many more), alongside multiple server implementations, so learners can compare idioms without guessing about feature gaps. A shared API contract and test suite keep implementations consistent and reveal framework-specific tradeoffs clearly. ... -

Prompt Engineering Interactive Tutorial
Anthropic's Interactive Prompt Engineering Tutorial
...It starts with the anatomy of a good prompt and moves into techniques that deliver the “80/20” gains—separating instructions from data, specifying schemas, and setting evaluation criteria. The course leans heavily on realistic failure modes (ambiguity, hallucination, brittle instructions) and shows how to iteratively debug prompts the way you would debug code. Lessons include building prompts from scratch for common tasks like extraction, classification, transformation, and step-by-step reasoning, with checkpoints that let you compare your outputs against solid baselines. ... -

Filament
Real-time physically based rendering engine for Android, iOS, and more
...For both artists and developers, our system will rely on as few parameters as possible to reduce trial and error and allow users to quickly master the material model. A physically based approach must not preclude non-realistic rendering. User interfaces for instance will need unlit materials. Our primary goal is to design and implement a rendering system able to perform efficiently on mobile platforms. -

XiangShan
Open-source high-performance RISC-V processor
...The project invests heavily in verification: differential testing against reference models, extensive random instruction tests, and full software stacks (bootloaders, Linux) to validate correctness under realistic workloads. Tooling around the core (build scripts, simulators, waveform/debug support) lowers the barrier for academics and industry contributors to experiment and extend. -

Size Limit
Calculate the real cost to run your JS app or lib
Size Limit is a JavaScript performance budget tool that measures the real cost of your JavaScript bundle and prevents regressions by enforcing limits in CI. It calculates not just raw bundle size, but also download and execution time under configurable network conditions, giving a more realistic sense of what users experience. The tool is modular: it offers a CLI and multiple plugins (file, webpack, time) plus presets tailored to different use cases, from big single-page apps to small npm libraries. When integrated with GitHub Actions, CircleCI, or other CI systems, it runs on every commit or pull request, failing the pipeline if a change exceeds the configured budget. ... -

Design Patterns Library
A comprehensive design patterns library implemented in C#
A comprehensive design patterns library implemented in C#, which covers various design patterns from the most commonly used ones to the lesser-known ones. Get familiar with and learn design patterns through moderately realistic examples. In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn't a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations. In addition, design patterns allow developers to communicate using well-known, well-understood names for software interactions. ... -
