The Pope Bot
Autonomous AI agent that you can configure and build
The Pope Bot is an autonomous AI agent framework that lets users configure and run an AI-powered agent that can perform tasks continuously, day in and day out, by leveraging GitHub Actions, commit history, and secure workflows. It’s designed so that every action taken by the agent is logged as a git commit, giving users complete visibility into what the agent did, why it did it, and when, which makes actions auditable and reversible. The framework treats the repository itself as the agent’s “brain,” and GitHub Actions serve as the compute layer, enabling tasks to run securely without exposing sensitive API keys to the underlying AI. The system integrates with messaging platforms like Telegram, where users can interact with the bot, trigger actions, or receive notifications, and supports scheduling and automation through patterns of request handling. -

TopoJSON
An extension of GeoJSON that encodes topology
TopoJSON eliminates redundancy, allowing related geometries to be stored efficiently in the same file. For example, the shared boundary between California and Nevada is represented only once, rather than being duplicated for both states. A single TopoJSON file can contain multiple feature collections without duplication, such as states and counties. Or, a TopoJSON file can efficiently represent both polygons (for fill) and boundaries (for stroke) as two feature collections that share the same arc mesh. See How To Infer Topology for a visual explanation of how TopoJSON works. See Command-Line Cartography for an introduction to TopoJSON and related tools. See TopoJSON Format Specification for the format specification. To further reduce file size, TopoJSON can use quantized delta-encoding for integer coordinates. This is similar to rounding coordinate values (e.g., LilJSON), but with greater efficiency and control over loss of information. -

Vue Meta
Manage HTML metadata in Vue.js components with SSR support
Vue Meta is a Vue.js plugin that allows you to manage your app's metadata. It is inspired by and works similar as react-helmet for react. However, instead of setting your data as props passed to a proprietary component, you simply export it as part of your component's data using the meta info property. These properties, when set on a deeply nested component, will cleverly overwrite their parent components' metaInfo, thereby enabling custom info for each top-level view as well as coupling metadata directly to deeply nested subcomponents for more maintainable code. -

WTFJS
A list of funny and tricky JavaScript examples
WTFJS is a curated collection of JavaScript “gotchas” and puzzling examples that reveal surprising corners of the language. Each entry presents a small snippet, explains why the behavior occurs, and ties it back to the specification or engine rules. The repository covers coercion quirks, edge-case comparisons, floating-point oddities, prototype traps, and scoping pitfalls, among others. It’s designed as both a fun read and a serious learning aid, helping developers build an intuition for how JavaScript evaluates expressions. By highlighting common misconceptions, it encourages safer coding patterns and more reliable mental models. Teachers, interviewers, and learners use it to spark discussion and deepen understanding of JavaScript’s semantics. -

Wasp
A programming language that understands what a web app is
Wasp (Web Application Specification Language) is a declarative DSL (domain-specific language) for developing, building and deploying modern full-stack web apps with less code. Concepts such as app, page, user, login, frontend, production, etc. are baked into the language, bringing a new level of expressiveness and allowing you to get more work done with fewer lines of code. While describing high-level features with Wasp, you still write the rest of your logic in your favorite technologies (currently React, NodeJS, Prisma). Wasp is in alpha and is therefore likely to change a lot, have bugs and miss important features. Due to its expressiveness, you can create and deploy a production-ready web app from scratch with very few lines of concise, consistent, declarative code. When you need more control than Wasp offers, you can write code in existing technologies such as js/html/css/... and combine it with Wasp code! -

analytics.js boilerplate
Examples and best practices for using analytics.js
analyticsjs-boilerplate is a reference implementation for using Google Analytics analytics.js on modern websites. It collects best practices for tracking page views, user interactions, errors, performance metrics, and custom events in a structured way. The project was created to help developers avoid scattered analytics snippets and instead start from a cleaner, more maintainable setup. It includes patterns for organizing analytics logic, reporting useful metrics, and making implementation decisions more deliberate. While analytics.js itself is now a legacy Google Analytics library, the repository remains useful as a historical and educational reference for analytics architecture. Its main value is showing how to treat analytics as a thoughtful engineering layer rather than a pile of ad hoc tags. -

bootstrap-select
The jQuery plugin that brings select elements into the 21st century
The jQuery plugin that brings select elements into the 21st century with intuitive multiselection, searching, and much more. Now with Bootstrap 4 support. Bootstrap-select requires jQuery v1.9.1+, Bootstrap’s dropdown.js component, and Bootstrap's CSS. If you're not already using Bootstrap in your project, a precompiled version of the Bootstrap v3.4.1 minimum requirements can be downloaded. If using bootstrap-select with Bootstrap v4+, you'll also need Popper.js. For all of Bootstrap v4's requirements, see Getting started. A precompiled version of the requirements will be made available in an upcoming release of bootstrap-select. Bootstrap 4 only works with bootstrap-select v1.13.0+. By default, bootstrap-select automatically detects the version of Bootstrap being used. However, there are some instances where the version detection won't work.
