    OSX Serial Generator

    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. ...

    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. ...

    Courses (Anthropic)

    Anthropic's educational courses

    ...Each course mixes short readings with runnable notebooks and exercises, guiding you through concepts like model parameters, streaming, multimodal prompts, structured outputs, and evaluation. Assignments emphasize realistic tasks such as building small utilities, testing prompts against edge cases, and measuring quality so you learn to ship things that work. The materials are written for developers but remain friendly to newcomers, with clear setup instructions and minimal boilerplate. Because the repo is live and maintained, lessons are updated as the SDK and models evolve, and issues are used to track fixes, clarifications, and new modules.

    Rust Latam

    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.

    ...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.

    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. ...

    Size Limit

    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. ...

    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. ...

    Spring Cloud Examples

    Spring Cloud Examples

    Spring Cloud learning cases, service discovery, service governance

    ...It provides working codebases showing how to wire together service discovery, configuration, inter-service communication, and possibly resilience patterns — giving developers a hands-on playground rather than theoretical documentation. By studying the examples, one can understand how Spring Cloud works in practice: how to structure services, how to configure them, and how they interact under realistic conditions. For developers new to microservices or to Spring Cloud, this repo lowers the barrier to adoption by offering a ready-made baseline they can inspect, run, and modify. It can also function as a reference when designing architecture for a cloud-native backend, or as a starting point for a new microservices project.
