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. -

Dexie.js
A Minimalistic Wrapper for IndexedDB
Dexie was written to be straightforward and easy to learn. If you've ever had to work with native IndexedDB then you'll certainly appreciate Dexie's concise API. What good is any development tool without great documentation? Dexie is thoroughly explained, and examples are available to help you on your way. Dexie has near-native performance. Its bulk operations utilize an often-overlooked feature in IndexedDB, ignoring success callbacks when possible. Offline databases are groovy! But without keeping the database in sync with a server, you're missing a great deal. Dexie.js solves these limitations and provides a neat database API. Dexie.js aims to be the first-hand choice of a IDB Wrapper Library due to its well thought-through API design, robust error handling, extendability, change tracking awareness and its extended KeyRange support (case insensitive search, set matches and or operations). -

Moment.js
Parse, validate, manipulate, and display dates in javascript
Moment is a JavaScript date and time library that simplifies parsing, formatting, arithmetic, and humanizing of dates. It supports many formats in input and output, internationalization (i18n), locale-based month/day names, relative time (for example, “3 days ago”), and chaining of operations (adding, subtracting, diffing). Developers often use it for calendar displays, scheduling, and manipulating times across time zones or daylight saving transitions. While it makes working with date strings convenient, moment maintains internal mutability, which has trade-offs with safety and chainability. Over time, newer alternatives with immutable and modular designs have emerged, but moment remains widely known and integrated in many legacy projects. Its comprehensive feature set and ease of use made it a standard for date-time handling in JavaScript for many years. -

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. -

HyperUI
Free Tailwind CSS v4 components for your next project
HyperUI is a large, copy-and-paste library of Tailwind CSS components aimed at speeding up interface building without adding heavy JavaScript. It groups components by common product needs—navigation, hero sections, pricing, forms, cards, tables, and full e-commerce flows—so teams can assemble pages quickly from consistent building blocks. Each snippet is written as semantic HTML with Tailwind utility classes, making it easy to customize spacing, color, and typography through a project’s Tailwind config. The components are responsive by default, using grid and flex patterns that adapt cleanly from mobile to widescreen layouts. Accessibility is treated pragmatically: markup favors proper roles and focus states, and most interactive behaviors can be wired with lightweight libraries or framework code if desired. Because everything is plain markup, adoption is frictionless in any stack (React, Vue, Svelte, Rails, Laravel), and designers can tweak styling without refactoring component logic.
