    MongoDB NodeJS Driver

    MongoDB NodeJS Driver

    The MongoDB Node.js driver

    The MongoDB Node.js driver allows Node.js applications to connect to MongoDB and work with data. The driver features an asynchronous API which allows you to interact with MongoDB using Promises or via traditional callbacks. Whether you are new to MongoDB or you just want to brush up on the core concepts, you can check out the Fundamentals section which features material on using the Node.js driver. The connection URI is the set of instructions that the driver uses to connect to a MongoDB deployment. It instructs the driver on how it should connect to MongoDB and how it should behave while connected. The Authentication Mechanisms guide contains sample connection code using each authentication mechanism supported in the MongoDB Community Edition. The Node.js driver uses the asynchronous Javascript API to communicate with your MongoDB cluster. Asynchronous Javascript allows you to execute operations without waiting for the processing thread to become free.

    P3X OneNote Linux

    P3X OneNote Linux

    Linux Electron Onenote - A Linux compatible version of OneNote

    P3X OneNote Linux is, actually, an independent browser window for the online OneNote. You can use this program without having to clutter your browser. The main functions are that is independent from any browser, as it works in it's own process. It provides a tray, that allows you to close your browser while it keeps running in the tray. The data is cached and is faster than always opening a new window. It allows you to sign in with the corporate or the personal login. When there is a new update, it auto updates itself (Only in the AppImage version.) The program allows to use other Microsoft online applications, but the dedicated purpose is to use OneNote. The OneNote language is controlled by Microsoft, and we try to work with Online OneNote, but we are getting a hard time, but the Electron UI is now able to use any language.

    Return YouTube Dislike

    Return YouTube Dislike

    Chrome extension to return youtube dislikes

    Return YouTube Dislike is an open-source extension that returns the YouTube dislike count. Available for Chrome and Firefox as a Web Extension. Also available for other browsers as JS Userscript. Additionally, the dislike field in the YouTube API was removed on December 13th, 2021, removing any ability to judge the quality of content before watching. With the removal of dislike stats from the YouTube API, our backend switched to using a combination of scraped dislike stats, and estimates extrapolated from extension user data. None existing YouTube ID will return status code 404 "Not Found". Wrong formed YouTube ID will return 400 "Bad Request".

    Teachable Machine

    Teachable Machine

    Explore how machine learning works, live in the browser

    Teachable Machine is the open-source implementation of an experimental machine learning tool created by Google Creative Lab that allows users to train simple machine learning models directly in a web browser. The project demonstrates how neural networks can be trained interactively using images captured from a webcam or other inputs without requiring programming knowledge. Users can provide example images for different categories, and the system trains a model that learns to classify those inputs in real time. The project is built using web technologies and the TensorFlow.js ecosystem, enabling machine learning models to run locally within the browser environment. Because the training occurs locally, the system can respond quickly to new examples and provide immediate feedback to users.

    ungit

    ungit

    A tool to simplify the use of git, on any platform, anywhere

    Git is known for being a versatile distributed source control system that is a staple of many individuals, communities, and even for the City of Chattanooga to crowd source bicycle parking locations. However, it is not known for userfriendliness or easy learning curve. Ungit brings user friendliness to git without sacrificing the versatility of git. Git and github both supports PGP signing. Within Ungit these features can be enabled. Currently, Ungit DOES NOT support GPG authentication! While git allows robust programmatic authentication via credential-helper, I could not find an easy way to do something equivalent with GPG. Therefore, password-less gpg authentication or 3rd party gpg password must be configured when using Ungit to commit with gpg. Ungit will watch git directory recursively upon page view and automatically refresh contents on git operations or changes on files that are not configured to be ignored in .gitignore.

    XOOPS Web Application System

    XOOPS Web Application System

    The world's leading content management systems (CMS) written in PHP

    PLEASE NOTE: Latest XOOPS files are on http://github.com/xoops and http://github.com/xoopsmodules25x) XOOPS is a Web application platform written in PHP for the MySQL database. Its object orientation makes it an ideal tool for developing small or large community websites, intra-company and corporate portals, weblogs, and much more. XOOPS is an acronym of eXtensible Object Oriented Portal System. Initially a portal system, XOOPS is now a leading content management system (CMS) that serves as a versatile Web framework. XOOPS can also be used as a weblog or journal via a standard install using the News module alone. Another approach is to use modules like News, Forum, Download, Web Links, etc. to form a community that interacts with members and visitors. Or think big, like an enterprise, and develop modules to use with eShop that integrate into XOOP's uniform user management system. XOOPS is released under the terms of the GNU General Public License (GPL)

    Alpine.js

    Alpine.js

    A rugged, minimal framework for composing JavaScript behavior

    Alpine.js is a lightweight JavaScript framework designed to bring declarative, reactive behavior directly into HTML markup, functioning similarly in spirit to Vue but with a much smaller footprint. It’s often described as “jQuery for the modern web,” enabling you to sprinkle interactivity onto static HTML without needing a full SPA framework. You use directives like x-data, x-bind, x-on, x-if, and others to attach reactive state, event listeners, and conditional rendering straight in the DOM. Because Alpine is so minimal, it avoids virtual DOM overhead and focuses on being incremental and composable; you can use it for small interactive components inside traditional server-rendered pages. The project has grown a robust ecosystem (plugins, devtools, helper libraries) as people adopt it for micro-frontend patterns, admin panels, interactive widgets, and anything that benefits from having bits of reactivity without a heavy JavaScript framework.

    Earth Engine API

    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.

    Electron Packager

    Electron Packager

    Customize and package your Electron app with OS-specific bundles

    Electron Packager is a command line tool and Node.js library that bundles Electron-based application source code with a renamed Electron executable and supporting files into folders ready for distribution. For creating distributables like installers and Linux packages, consider using either Electron Forge (which uses Electron Packager internally), or one of the related Electron tools, which utilizes Electron Packager-created folders as a basis. Note that packaged Electron applications can be relatively large. A zipped, minimal Electron application is approximately the same size as the zipped prebuilt binary for a given target platform, target arch, and Electron version (files named electron-v${version}-${platform}-${arch}.zip). Building an Electron app for the Windows target platform requires editing the Electron.exe file. Currently, Electron Packager uses node-rcedit to accomplish this.
