    HLS.js

    HLS.js

    HLS.js is a JavaScript library that plays HLS in browsers

    HLS.js is a JavaScript library that implements an HTTP Live Streaming client. It relies on HTML5 video and MediaSource Extensions for playback. It works by transmuxing MPEG-2 Transport Stream and AAC/MP3 streams into ISO BMFF (MP4) fragments. Transmuxing is performed asynchronously using a Web Worker when available in the browser. HLS.js also supports HLS + fmp4, as announced during WWDC2016. HLS.js works directly on top of a standard HTML<video> element. HLS.js is written in ECMAScript6 (*.js) and TypeScript (*.ts) (strongly typed superset of ES6), and transpiled in ECMAScript5 using Babel and the TypeScript compiler. Webpack is used to build the distro bundle and serve the local development environment.

    Heritrix

    Heritrix

    Internet Archive's open-source, web-scale, web crawler project

    Heritrix is the Internet Archive's open-source, extensible, web-scale, archival-quality web crawler project. Heritrix (sometimes spelled heretrix, or misspelled or missaid as heratrix/heritix/heretix/heratix) is an archaic word for heiress (woman who inherits). Since our crawler seeks to collect and preserve the digital artifacts of our culture for the benefit of future researchers and generations, this name seemed apt. Heritrix is designed to respect the robots.txt exclusion directives† and META nofollow tags. Please consider the load your crawl will place on seed sites and set politeness policies accordingly. Also, always identify your crawl with contact information in the User-Agent so sites that may be adversely affected by your crawl can contact you or adapt their server behavior accordingly.

    QuarkPanTool

    QuarkPanTool

    A tool for batch transferring, sharing and downloading quark network

    QuarkPanTool is a command-line utility for batch operations with Quark cloud-drive files and shared links. It can transfer files from multiple shared URLs into a user's own drive in one workflow. The program can also generate sharing links in bulk for folders already stored in the account. Local downloading is supported for batches of cloud files instead of requiring one-by-one retrieval through the website. Playwright handles browser-based login and can preserve the authenticated session, while manual cookies are also supported. The interface is intentionally simple and packaged Windows executables are available in addition to running the Python source. The project is aimed at reducing repetitive cloud-drive management work when many Quark links or files must be processed together.

    RetrofitUrlManager

    RetrofitUrlManager

    Let Retrofit support multiple baseUrl and can be change the baseUrl

    RetrofitUrlManager is an Android networking utility built on top of Retrofit and OkHttp that enables applications to support multiple base URLs and dynamically switch endpoints at runtime. The library simplifies complex networking architectures where apps interact with multiple APIs, environments, or microservices without requiring developers to rebuild Retrofit instances manually. It works by intercepting outgoing requests and replacing or modifying the target domain through a centralized management layer. The project is especially useful in modular Android applications, debugging environments, multi-tenant systems, and apps requiring dynamic API routing. RetrofitUrlManager integrates seamlessly into existing Retrofit workflows with minimal configuration while preserving compatibility with OkHttp interceptors and Retrofit annotations. Its design prioritizes flexibility, runtime configurability, and reduced boilerplate in Android networking stacks.

    Stanza is a collection of accurate and efficient tools for the linguistic analysis of many human languages. Starting from raw text to syntactic analysis and entity recognition, Stanza brings state-of-the-art NLP models to languages of your choosing. Stanza is a Python natural language analysis package. It contains tools, which can be used in a pipeline, to convert a string containing human language text into lists of sentences and words, to generate base forms of those words, their parts of speech and morphological features, to give a syntactic structure dependency parse, and to recognize named entities. The toolkit is designed to be parallel among more than 70 languages, using the Universal Dependencies formalism. Stanza is built with highly accurate neural network components that also enable efficient training and evaluation with your own annotated data.

    Style2Paints

    Style2Paints

    Sketch + style = paints

    style2paints is an AI-assisted colorization system aimed primarily at line art and manga, turning monochrome drawings into colored illustrations with minimal manual effort. It combines automatic color inference with user guidance, letting artists nudge the model using sparse color hints, masks, or style references. The pipeline focuses on preserving line quality while spreading coherent colors and shading across regions that are often ambiguous to purely automatic methods. Iterative refinement is a core workflow: you can add or adjust hints, rerun inference, and progressively converge on a desired palette and lighting. Beyond flat fills, the model attempts plausible shading and highlights so the result feels less like a “paint bucket” and more like a finished illustration. Because it’s built for artists rather than only researchers, the project emphasizes an approachable UI, predictable edits, and reproducible outputs across sessions.

    pytz

    Python historical timezone library and database

    pytz is a Python library that brings the IANA/Olson timezone database into the Python runtime, enabling accurate, cross-platform timezone calculations for all the world’s timezones. It addresses a major limitation of Python’s built-in datetime.tzinfo by providing consistent support for daylight-saving transitions, historical offset changes, and ambiguous times (such as the end of DST). With pytz, developers can convert naïve datetime objects into timezone-aware ones, shift between timezones, and safely perform arithmetic across DST boundaries with methods like localize() and normalize(). Although Python 3.9 and newer include better built-in timezone support (via zoneinfo and external packages like tzdata), pytz remains widely used—especially in legacy codebases or in environments where backward compatibility matters.
