Earth Engine API
Python and JavaScript bindings for calling the Earth Engine API
The Earth Engine API provides Python and JavaScript client libraries for Google Earth Engine, a planetary-scale geospatial analysis platform. With it, users compose lazy, server-side computations over massive catalogs of satellite imagery and vector datasets without handling raw files locally. The API exposes functional operators for map algebra, reducers, joins, and machine learning that scale transparently on Earth Engine’s backend. Developers authenticate once, work interactively in notebooks or the Code Editor, and export results to Cloud Storage, Drive, or asset collections. Visualization helpers render tiled layers and charts so analysts can iterate quickly on workflows like land-cover mapping, change detection, or time-series analysis. By combining petabyte-scale data with concise functional transforms, the API turns complex remote-sensing pipelines into reproducible scripts that are easy to share. -

GitHub Dark
Dark GitHub style
GitHub-Dark is a userstyle that transforms GitHub’s interface into a coherent dark theme, covering repositories, issues, pull requests, gists, and profile pages. Distributed as a CSS stylesheet intended for the Stylus browser extension, it applies a comprehensive palette, rebalances contrast, and refines syntax colors for code views to ensure readability in low-light settings. The project goes beyond simple inversion by thoughtfully adjusting backgrounds, borders, badges, and diff highlights so the UI feels native rather than “flipped.” It includes targeted fixes for edge cases across GitHub’s many subpages, aiming for consistency while preserving the information hierarchy of the original design. Users can apply the theme selectively, override variables, or combine it with other userstyles to fit personal preference. Even with GitHub’s own theme options, GitHub-Dark remains a carefully tuned alternative for people who want a specific aesthetic or more granular control. -

Markdown
WeChat Markdown Editor
WeChat Markdown Editor | A highly concise WeChat Markdown editor, that supports Markdown syntax, color palette selection, multi-image upload, one-click document download, custom CSS style, one-click reset, and other features. Markdown documents are automatically rendered into WeChat graphics and text in real-time, so you no longer have to worry about the typesetting of WeChat articles! As long as you know the basic Markdown syntax, you can make a simple and beautiful WeChat graphic. Chrome browser is recommended for best results. In addition, for domestic (China) friends, accessing Gitee Pages will be relatively faster. The existing open-source WeChat Markdown editor has complicated styles and does not meet my personal aesthetic needs. When I use them for article typesetting, I often have to make some changes myself, which is time-consuming and labor-intensive, so I did secondary development. -

ARC-AGI
The Abstraction and Reasoning Corpus
ARC-AGI is a benchmark dataset and experimental framework designed to evaluate and advance artificial general intelligence by testing systems on abstract reasoning tasks that require human-like problem-solving abilities. It consists of a curated set of tasks where models must infer patterns from input-output examples and apply those rules to new unseen cases, without relying on memorization or prior training data. The dataset is structured as grid-based puzzles, where each task requires understanding transformations such as symmetry, counting, or spatial manipulation. Unlike traditional machine learning benchmarks, ARC emphasizes generalization and reasoning over statistical pattern recognition, making it particularly challenging for current AI systems. The repository also includes a browser-based interface that allows humans to attempt solving the tasks manually, providing a baseline for comparison. -

Advanced REST Client application
Advanced REST Client - Desktop application
This is the main repository for the ARC Electron application. If you are still using Chrome plug-in then proceed to move From Chrome To the Desktop Client section. The original Chrome application is discontinued as Chrome stopped supporting browser-based applications. ARC was built as an open-source and free for everyone API tool out of a passion for giving the developer community tools they need. The application and related projects (like API Console) are created and distributed to our users for free. Our vision is that API tools are available for every developer and organization, regardless of their size, for free and without forced relationship. API tools are using open standards to communicate with other applications so developers can build integrations. Originally the application was created by the author for own convenience while developing APIs. It quickly turned out to be a common problem among developers to consume APIs during the development process. -

Calibre-Web Automated
Calibre-Web but Automated and with tons of New Features
Calibre-Web-Automated (CWA) is an all-in-one, self-hosted solution for managing an ebook library that combines the modern, lightweight web UI style of Calibre-Web with the deeper tooling and conversion capabilities associated with Calibre. The goal is to reduce the common “two-service” setup where users run Calibre-Web for browsing and Calibre separately for conversions, metadata fixes, and automation, by packaging those workflows together in a single system. CWA keeps the familiar strengths of Calibre-Web, like a responsive interface, OPDS feeds for e-readers, and strong user/permission management, while layering in extensive automation features that handle ingest, conversion, metadata enforcement, and library organization with less manual effort. It also expands authentication options (including modern OAuth/OIDC flows) and adds quality-of-life improvements such as enhanced search/filtering, multi-language UI support, and better device-centric workflows for sending to e-readers. -
