    NSubstitute

    NSubstitute

    A friendly substitute for .NET mocking libraries

    ...It is an attempt to satisfy our craving for a mocking library with a succinct syntax that helps us keep the focus on the intention of our tests, rather than on the configuration of our test doubles. We've tried to make the most frequently required operations obvious and easy to use, keeping less usual scenarios discoverable and accessible, and all the while maintaining as much natural language as possible. There are already some great mocking libraries around for .NET, so why create another? We found that for all their great features, none of the existing libraries had the succinct syntax we were craving — the code required to configure test doubles quickly obscured the intention behind our tests.

    whoami.filippo.io

    whoami.filippo.io

    A ssh server that knows who you are. $ ssh whoami.filippo.io

    ...It is especially helpful when validating modern TLS features like ALPN, HTTP versions, and certificate behavior under different client stacks. Because the output is human-friendly, it doubles as an educational resource for understanding how transport and application-layer negotiations actually manifest. Teams use it to troubleshoot misconfigurations and confirm policy enforcement without setting up their own inspection endpoints.

    GuitarPedal

    GuitarPedal

    Linus learns analog circuits

    ...It emphasizes straightforward, inspectable DSP so developers can follow the math and tweak parameters without a giant framework in the way. The codebase favors portability and simplicity, focusing on a handful of canonical effects rather than a sprawling plugin architecture. It doubles as a teaching aid for musicians who code, showing how buffers, sampling rates, and numerical stability affect tone. While not a full multi-FX suite, it offers a compact sandbox for experimenting with guitar processing on modest hardware.

    Node.js Testing Best Practices

    Node.js Testing Best Practices

    Beyond the basics of Node.js testing

    ...The material explains how to structure tests around process boundaries—HTTP, queues, cron jobs—while keeping fast feedback cycles through selective integration tests and reliable test doubles. It dives into topics like test containers, ephemeral databases, and idempotent fixtures to ensure deterministic runs in CI. Observability is treated as part of testing: logs, metrics, and tracing make failures diagnosable instead of mysterious. By aligning tests with service responsibilities instead of internal modules, the guide helps teams produce suites that reflect real production behavior.

    type-challenges

    type-challenges

    Collection of TypeScript type challenges with online judge

    ...Problems are arranged from warm-ups to brain-twisters, letting developers build intuition about distributive conditional types, inference in extends, variance, and other corner cases of the type system. The repository includes tests for each puzzle so you get immediate, compiler-driven feedback when your solution is correct. As a result, it doubles as both training material and a living reference for advanced patterns used in real libraries. Many engineers report that solving a handful of these dramatically improves their ability to write safe, expressive APIs with minimal runtime overhead.

    A runtime developer console and IRB alternative

    Pry is a powerful alternative to Ruby’s default REPL that doubles as a runtime exploration and debugging toolkit. It offers command-driven navigation of objects and modules, syntax-highlighted input, command history, and the ability to switch contexts or “cd” into objects to inspect their methods and state. Features like show-source and show-doc reveal the implementation or documentation of methods without leaving the console, while edit-method lets you jump into an editor, modify code, and reload it on the fly. ...

    Free Fps. Video FPS Converter

    Free Fps. Video FPS Converter

    Desktop app to change a video FPS

    ...Unlike video editors, it does not add effects or alter content - it only adjusts playback speed and, if needed, re-encodes audio as well. Useful if you work with multiple videos shot at different frame rates that cannot be combined or edited without interpolation or frame loss. Also doubles as a fast video compressor: keep the original FPS and raise compression (e.g., higher CRF or lower bitrate) to reduce file size. What it does: Changes video FPS via FFmpeg. Keeps or re‑encodes audio if requested. No effects, no content edits. Writes results to a separate output folder by default. Also doubles as a fast video compressor: keep the original FPS and raise compression (e.g., higher CRF or lower bitrate) to reduce file size. ...

    daily-paper-computer-vision

    Document papers compiled daily in computer vision/deep learning

    ...The cadence is intentionally frequent, reflecting how quickly CV advances and how hard it is to maintain awareness while working full time. By aggregating paper titles and references in one place, it reduces the overhead of deciding what to read next and helps you spot trends early. It doubles as a personal knowledge log: you can star or fork it to build your own “to-read” roadmap. For students and engineers alike, it’s a practical way to stay research-literate without getting overwhelmed.

    Ambient

    Ambient

    The multiplayer game engine

    Ambient is an open-source, cross-platform runtime and engine for building and deploying high-performance multiplayer games and 3D applications, using a modern stack built on Rust, WebAssembly (WASM), and WebGPU. It aims to make multiplayer game development accessible and flexible, providing an entity-component-system (ECS) at its core that doubles as a real-time in-game database; everything in the game — from world objects to runtime data — is represented as entities + components, which can be synchronized across clients automatically. Ambient supports a package-based workflow reminiscent of Rust’s crate system, where “packages” bundle code, assets, and schema definitions; this modular design encourages reuse, mixing, and sharing of content. ...

    Pinject

    Pinject

    A pythonic dependency injection library

    Pinject is a lightweight dependency-injection library for Python that favors explicit wiring and testability over magic. Instead of global singletons, you declare providers (bindings) that describe how to construct objects, and Pinject resolves the graph by inspecting call signatures. Its container supports constructor injection and fine-grained scoping so you can share expensive resources while keeping tests isolated. The library leans on Python’s introspection to minimize boilerplate,...
