    fp-ts

    fp-ts

    Functional programming in TypeScript

    fp-ts provides developers with popular patterns and reliable abstractions from typed functional languages in TypeScript. The goal of fp-ts is to empower developers to write pure FP apps and libraries built atop higher order abstractions. It includes the most popular data types, type classes, and abstractions from languages like Haskell, PureScript, and Scala. Functional programming is all about pure functions and how to compose them into bigger structures. fp-ts provides a few general functions to support you with composition, constant functions, and more. ...

    Doctrine Lexer

    Doctrine Lexer

    Base library for a lexer that can be used in Recursive Descent Parsers

    ...To write your own parser you just need to extend Doctrine\Common\Lexer\AbstractLexer and implement three abstract methods. These methods define the lexical catchable and non-catchable patterns and a method for returning the type of a token and filtering the value if necessary. The Lexer is responsible for giving you an API to walk across a string one character at a time and analyze the type of each character, value and position of each token in the string. The low level API of the lexer is pretty simple. The setInput($input) option sets the input data to be tokenized. ...

    Apache Flink

    Apache Flink

    Stream processing framework with powerful stream

    ...Flink’s event-time model and watermarks enable accurate out-of-order processing, windowing, and complex time semantics that typical real-time systems struggle with. Developers program against high-level APIs—DataStream and Table/SQL—to express transformations, joins, and stateful patterns, while specialized libraries support CEP, machine learning workflows, and connectors. A rich connector ecosystem integrates with systems like Kafka, Kinesis, filesystems, JDBC sources/sinks, and object stores. Deployments span Kubernetes, YARN, Mesos, and standalone clusters, and operational features such as savepoints, state backends, and metrics make long-running jobs manageable in production.

    mall-admin-web

    mall-admin-web

    frontend component of the “mall” e-commerce system

    ...It demonstrates how a modern single-page application can be structured to integrate with the backend services described in the learning / microservice projects, including authentication (JWT or token), REST APIs, role/permission management and real-time dashboards. The codebase offers modular UI architecture, Vue component patterns, dynamic menu and permission handling, and visualization of statistics and reports. For teams building an admin portal or internal operations system, this project provides a concrete blueprint for UI design, API integration, state management and role-based access control. It also shows how to work with enterprise features (search, pagination, batch actions, uploads) in a consistent framework.

    ...The repository is structured to show how cross-service concerns like service registry, configuration center, monitoring, distributed transactions, API gateway and messaging are done in microservice architecture. It is used as a teaching platform to help engineers migrate from monolith to microservices, grasp the patterns, pitfalls and infrastructure considerations (e.g., Nacos, Seata). The documentation includes diagrams of system architecture, business architecture, service organization, and shows how to set up on Kubernetes.

    Playground Cheatsheet for Python

    Playground Cheatsheet for Python

    Playground and cheatsheet for learning Python

    ...The design supports “learn by doing”: you can modify the code, run the tests, see how behavior changes, and thus internalize Python language features, idioms, and good style practices (including linting and PEP8). Because it is organized in bite-sized chunks, it’s ideal for beginners or people refreshing their Python skills who want to revisit syntax and common patterns before moving into larger frameworks or applications. It also supports usage as a reference: if you forgot how a list comprehension works or how decorators behave, you can quickly open the relevant script.

    Fast strong hash functions: SipHash/HighwayHash

    ...Typical uses include protecting hash tables that store untrusted keys and authenticating short-lived messages or records in storage systems. Although not a replacement for collision-resistant digests like SHA-2/3, it strikes a pragmatic balance of speed, simplicity, and resistance to common abuse patterns seen in production backends.

    Swift Algorithm Club

    Swift Algorithm Club

    Algorithms and data structures in Swift, with explanations

    ...The repository includes common classic algorithms (sorting, searching, trees, graphs, dynamic programming, etc.) and structures (queues, heaps, tries, balanced trees) along with writeups explaining them. Because it's in Swift, the code is idiomatic and leverages Swift language features and standard patterns, which helps learners see how algorithmic ideas map into modern code. Many of the algorithms come with test harnesses so you can run them and experiment.

    eslint-plugin-testing-library

    eslint-plugin-testing-library

    ESLint plugin to follow best practices and anticipate common mistakes

    ...With the default setup mentioned before, eslint-plugin-testing-library will be run against your whole codebase. You can run this plugin only against your tests files. One way of restricting ESLint config by file patterns is by using ESLint overrides. Another approach for customizing ESLint config by paths is through ESLint Cascading and Hierarchy. This is useful if all your tests are placed under the same folder, so you can place there another .eslintrc where you enable eslint-plugin-testing-library for applying it only to the files under such folder, rather than enabling it on your global .eslintrc which would apply to your whole project.

    Run linters against staged git files and don't let anything slip into your code base! Linting makes more sense when run before committing your code. By doing so you can ensure no errors go into the repository and enforce code style. But running a lint process on a whole project is slow, and linting results can be irrelevant. Ultimately you only want to lint files that will be committed. This project contains a script that will run arbitrary shell tasks with a list of staged files as an...

This makes it easy to integrate Groq-powered AI capabilities into backend services, data pipelines, research notebooks, or applications written in Python. For those building AI-based tooling, automation scripts, or ML-backed backends, groq-python abstracts away HTTP request plumbing and exposes a clean API, accelerating development and reducing boilerplate.

    Develop your applications directly in your Kubernetes Cluster

    Kubernetes has made it very easy to deploy applications to the cloud at a higher scale than ever, but the development practices have not evolved at the same speed as application deployment patterns. Today, most developers try to either run parts of the infrastructure locally or just test these integrations directly in the cluster via CI jobs, or the docker build/redeploy cycle. It works, but this workflow is painful and incredibly slow. Okteto accelerates the development workflow of Kubernetes applications. You write your code locally and okteto detects the changes and instantly updates your Kubernetes applications. ...

    zsh-syntax-highlighting is a lightweight Zsh plugin that adds real-time syntax coloring to your command line as you type. It highlights known commands, options, arguments, paths, strings, and glob patterns so you can catch typos or invalid commands before pressing Enter. Unknown or misspelled commands are styled differently from valid ones, making errors obvious at a glance. The plugin is written in pure Zsh and hooks into the line editor, so it doesn’t require external binaries and works across diverse environments. It’s highly configurable: you can fine-tune individual token styles, disable specific highlighters, or extend it with custom rules to match your workflow. ...

The library also supports streaming APIs, where the response arrives in chunks, using helpers like ChatCompletionAccumulator to accumulate partial responses into a full object. ...
