    Video Speed Controller

    Video Speed Controller

    HTML5 video speed controller (for Google Chrome)

    Video Speed Controller is a browser extension that gives users precise control over HTML5 video and audio playback. It works across many websites instead of depending on the controls offered by each individual player. Users can raise or lower playback speed, rewind, skip forward, reset the rate, and jump between a current and preferred speed. Its configurable range supports both unusually slow playback and speeds far beyond the limits of most media sites. The extension can remember settings, enforce a chosen rate when a site tries to change it, and apply rules by domain. A movable on-screen indicator keeps the current speed visible without replacing the original player. Custom keyboard shortcuts and CSS make the controller adaptable to different workflows and page layouts.

    Viewer.js

    Viewer.js

    JavaScript image viewer

    You may set viewer options with new Viewer(image, options). If you want to change the global default options, You may use Viewer.setDefaults(options). Enable the modal backdrop, specify static for the backdrop that will not close the modal on click. Specify the visibility and the content of the title. Filter the images for viewing (should return true if the image is viewable, return false to ignore the image). Indicate if toggle the image size between its natural size and initial size when double click on the image or not. As there are some asynchronous processes when start the viewer, you should call a method only when it is available. If you have to use another viewer with the same namespace, call the Viewer.noConflict static method to revert to it.

    csv-parser

    csv-parser

    Streaming csv parser inspired by binary-csv that aims to be faster

    csv-parser is a streaming CSV parsing library for Node.js designed for efficiency and correctness. It implements the stream API native to Node, allowing you to pipe a file or readable stream into the parser and process each row (as a JavaScript object or array) as soon as it's parsed — which is crucial for handling large CSV files without loading them entirely into memory. The parser handles standard CSV semantics including quoted fields, variable delimiters, escape sequences, and optional headers; this makes it robust for a variety of CSV dialects you might encounter. Because it works incrementally (row by row), it is well suited for ETL pipelines, data ingestion workflows, CSV-to-database imports, or any context where you need to process or transform large tabular data in Node.js efficiently. Using the .on('data') / .on('end') (or equivalent async patterns), you can accumulate, filter, transform, or stream data further downstream without waiting for the whole file.

    peerflix

    peerflix

    Streaming torrent client for node.js

    peerflix is a Node.js-based streaming torrent client that lets you stream video or audio files directly from a torrent (magnet link or .torrent file), without needing to wait for the entire download to finish. It spins up a small HTTP server that serves the torrent’s content as it’s downloaded; for example, if you point a media player (like VLC or MPV) to the provided URL, it will start playing almost immediately. Peerflix automatically selects the largest file in a multi-file torrent by default (or can list all files for manual selection), and supports passing arbitrary flags to the media player — letting you stream with subtitles, full-screen mode, or other player-specific options. Because it's built on the torrent peer network, it downloads pieces on demand as playback proceeds, which can be more efficient if you only want to watch a single file. Peerflix also exposes programmatic API usage using underlying low-level torrent-streaming logic.

    single-file-cli

    single-file-cli

    CLI tool to save complete web pages as single self-contained HTML file

    SingleFile CLI is an open source command-line tool designed to save complete web pages as a single self-contained HTML file. It captures the rendered page in a headless browser and embeds all required resources directly into the output document, including stylesheets, scripts, images, and fonts. By consolidating every dependency into one file, it allows users to preserve a faithful copy of a web page that can be viewed offline without requiring external assets. SingleFile CLI works by controlling a browser through the Chrome DevTools Protocol, rendering the page before extracting and packaging all necessary resources. This approach helps ensure that the saved page closely matches the original appearance and functionality. SingleFile CLI can be used for automated archiving, research, documentation, or offline reading workflows where preserving a page exactly as displayed is important.

    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.

    Algorithm Visualizer

    Algorithm Visualizer

    Interactive Online Platform that Visualizes Algorithms from Code

    Hacker Scripts is a light-hearted collection of small automation and demo scripts that solve amusing everyday tasks or illustrate quick integrations with external services. The repo collects short programs (originally a set of shell and Ruby scripts) and many community contributed ports in other languages to show “how you might automate X” — for example sending a quick SMS, firing off an email, or triggering a coffee maker — with examples and scheduling snippets included. The README explains each example, lists required environment variables or credentials (e.g., Twilio/Gmail where applicable), and gives cron examples so readers can run the scripts in a real environment. The project is intentionally informal and educational: it’s meant for experimentation, learning language-interop, and having fun rather than production-grade automation. Many implementations exist across languages (shell, Ruby, Python, Node, PowerShell, Go, Java, and more) and contributors are encouraged to add further

    Cloud Torrent

    Cloud Torrent

    Cloud Torrent, a self-hosted remote torrent client

    Cloud torrent is a a self-hosted remote torrent client, written in Go (golang). You start torrents remotely, which are downloaded as sets of files on the local disk of the server, which are then retrievable or streamable via HTTP. Go is required to install from source. The provided set of core features requires large structural changes and therefore requires a complete rewrite for best results. This rewrite is in progress in the 0.9 branch though it will take quite some time. It will be capable of transfering files from and source file-system to any destination file-system. A torrent can be viewed a folder with files, just like your local disk, and Dropbox. As long as it has a concept of files and folders, it could potentially be a cloud-torrent file-system backend. During a file tranfer, one could apply different transforms against the byte stream for various effect.

    Cropper.js

    Cropper.js

    JavaScript image cropper

    The size of the cropper inherits from the size of the image's parent element (wrapper), so be sure to wrap the image with a visible block element. If you are using cropper in a modal, you should initialize the cropper after the modal is shown completely. Otherwise, you will not get the correct cropper. The outputted cropped data is based on the original image size, so you can use them to crop the image directly. If you try to start cropper on a cross-origin image, please make sure that your browser supports HTML5 CORS settings attributes, and your image server supports the Access-Control-Allow-Origin option (see the HTTP access control (CORS)). You may set cropper options with new Cropper(image, options). If you want to change the global default options, You may use Cropper.setDefaults(options). Define the view mode of the cropper. If you set viewMode to 0, the crop box can extend outside the canvas, while a value of 1, 2, or 3 will restrict the crop box to the size of the canvas.
