    Darknet

    Darknet

    Convolutional Neural Networks

    Darknet is an open source neural network framework written in C and CUDA, developed by Joseph Redmon. It is best known as the original implementation of the YOLO (You Only Look Once) real-time object detection system. Darknet is lightweight, fast, and easy to compile, making it suitable for research and production use. The repository provides pre-trained models, configuration files, and tools for training custom object detection models. With GPU acceleration via CUDA and OpenCV integration, it achieves high performance in image recognition tasks.

    Flower

    Flower

    Flower: A Friendly Federated Learning Framework

    A unified approach to federated learning, analytics, and evaluation. Federate any workload, any ML framework, and any programming language. Federated learning systems vary wildly from one use case to another. Flower allows for a wide range of different configurations depending on the needs of each individual use case. Flower originated from a research project at the University of Oxford, so it was built with AI research in mind. Many components can be extended and overridden to build new state-of-the-art systems. Different machine learning frameworks have different strengths. Flower can be used with any machine learning framework, for example, PyTorch, TensorFlow, Hugging Face Transformers, PyTorch Lightning, scikit-learn, JAX, TFLite, MONAI, fastai, MLX, XGBoost, Pandas for federated analytics, or even raw NumPy for users who enjoy computing gradients by hand.

    Kreuzberg

    Kreuzberg

    Polyglot document intelligence framework

    Kreuzberg is a flexible task orchestration and agent workflow platform designed to help developers build, coordinate, and scale intelligent agents or automation pipelines that interact with external services, runtime environments, and multi-step business workflows. It emphasizes modular design so that developers can define discrete tasks or “actions” and then compose them into complex flows where dependencies, parallel steps, and error handling are declaratively managed. This structure makes it simpler to build resilient automation pipelines that span multiple technologies or APIs without needing to glue everything together manually. The platform also supports observability and monitoring, helping teams trace the progression of workflows, catch errors early, and evaluate performance trends in orchestrated systems.

    Motia

    Multi-Language Backend Framework that unifies APIs

    Motia is a large-scale, multi-language backend framework designed to unify and simplify core backend concerns — from APIs and background jobs to distributed workflows, streams, and advanced AI agent integration — through a single coherent primitive with built-in observability and state management. It provides a unified development philosophy that seamlessly bridges different backend patterns (queues, event streams, scheduled jobs) while offering integrated tools for telemetry, logging, metrics, and tracing to help teams maintain high visibility into production workloads. Motia is built with extensibility in mind, allowing engineers to define complex workflows and AI-driven processes without sacrificing consistency or scalability. Its modular architecture supports integration with existing systems, plug-in architectures, and dynamic environments, making it suitable for building microservices, enterprise applications, or large automated systems.

    Air Go

    Air Go

    Live reload for Go apps

    When I get started with developing websites in Go and gin framework, it's a pity that gin lacks live-reloading function. In fact, I tried fresh and it seems not much flexible, so I intended to rewrite it in a better way. Air is yet another live-reloading command line utility for Go applications in development. Just air in your project root directory, leave it alone, and focus on your code. For less typing, you could add alias air='~/.air' to your .bashrc or .zshrc. You can pass arguments for running the built binary by adding them after the air command.

Suitable for companies with the multi-language stack. Easy for go, python, php, nodejs, ruby and so forth. The only external dependence is the database server, easy to deploy, cluster, and scale horizontally. Supports TCC, SAGA, XA, and transaction messages. DTM is a distributed transaction framework that provides cross-service eventual data consistency. It provides saga, tcc, xa, 2-phase message, and outbox patterns for a variety of application scenarios. It also supports multiple languages and multiple store engines to form up a transaction.

    nFPM

    nFPM

    A simple deb, rpm and apk packager written in Go

    nFPM is a simple, 0-dependencies, deb, rpm, apk, and Arch Linux packager. While fpm is great, for me, it is a bummer that it depends on ruby, tar and other software. I wanted something that could be used as a binary and/or as a library and that was really simple. So I decided to create nFPM: a simpler, 0-dependency, as-little-assumptions-as-possible alternative to fpm. This is a subtle way of saying it won't have all features, nor all formats that fpm has: it is supposed to be simpler. And that's OK!, most of us don't need all those features most of the time. You create a YAML file with the definition of what you need, run the nfpm binary, and it takes care of everything. The same config file can be used to create both the RPM and Deb packages.

    Ethereum implementation on the efficiency frontier

    Erigon is an implementation of Ethereum (execution client), on the efficiency frontier, written in Go. For an Archive node of Ethereum Mainnet we recommend >=3TB storage space: 1.8TB state (as of March 2022), 200GB temp files (can symlink or mount folder <datadir>/etl-tmp to another disk). Ethereum Mainnet Full node ( see --prune* flags): 400Gb. Erigon by default is "all in one binary" solution, but it's possible start TxPool as separated processes. Same true about: JSON RPC layer (RPCDaemon), p2p layer (Sentry), history download layer (Downloader), consensus. Don't start services as separated processes unless you have clear reason for it: resource limiting, scale, replace by your own implementation, security. How to start Erigon's services as separated processes, see in docker-compose.yml.

    D2 is a diagram scripting language that turns text to diagrams. It stands for Declarative Diagramming. Declarative, as in, you describe what you want diagrammed, it generates the image. As well, the functioning of the install script is described in detail to alleviate any concern of its use. We recommend using your OS's package manager directly instead for improved security but the install script is by no means insecure. D2 includes a variety of official themes to style your diagrams beautifully right out of the box. See ./d2themes to browse the available themes and make or contribute your own creation. D2 is designed with language tooling in mind. D2's parser can parse multiple errors from a broken program, has an autoformatter, syntax highlighting, and we have plans for LSP's and more. Good language tooling is necessary for creating and maintaining large diagrams. D2 is designed to be extensible and composable.

It is now maintained by the Manim Community and permissively released under the MIT license. Manim was originally created by Grant Sanderson as a personal project and for use in his YouTube channel, 3Blue1Brown. As his channel gained popularity, many grew to like the style of his animations and wanted to use manim for their own projects. However, as manim was only intended for personal use, it was very difficult for other users to install and use it. Manim, or ManimCE refers to the community-maintained version of the library. This is the version documented on this website; the package name on PyPI is manim. ManimGL is the latest released version of the library developed by Grant “3b1b” Sanderson. It has more experimental features and breaking changes between versions are not documented.
