tmi.js
Javascript library for the Twitch Messaging Interface
Connect to and interact with Twitch chat (IRC) from Node.js or a browser. Control the delay in milliseconds between JOIN requests when using the channels array option. Minimum of 300 milliseconds. If the identity has special permission from Twitch for a higher join rate then you should implement your own calls to the client.join method. Disable receiving JOIN/PART events for other users. Good for decreasing network traffic when joining lots of channels or you don't care about this data. After a threshold per channel Twitch stops sending this data so it may not be necessary for all cases. Channels to automatically join upon connecting. The rate of joins is controlled by the options.joinInterval option. Automatically reconnect the client if it gets disconnected for any reason. Sometimes Twitch will request the client to reconnect and tmi.js will disconnect and reconnect even if this option is set to false. -

toastr
Simple javascript toast notifications
toastr is a Javascript library for Gnome / Growl type non-blocking notifications. jQuery is required. The goal is to create a simple core library that can be customized and extended. Toastr will supply default animations, so you do not have to provide any of these settings. However you have the option to override the animations if you like. Optionally override the animation easing to show or hide the toasts. Default is swing. swing and linear are built into jQuery. Use the jQuery show/hide method of your choice. These default to fadeIn/fadeOut. The methods fadeIn/fadeOut, slideDown/slideUp, and show/hide are built into jQuery. Rather than having identical toasts stack, set the preventDuplicates property to true. Duplicates are matched to the previous toast based on their message content. Control how toastr interacts with users by setting timeouts appropriately. Visually indicate how long before a toast expires. -

uemacs
Random version of microemacs with my private modificatons
uemacs is Linus Torvalds’ compact take on MicroEMACS, a tiny, fast, terminal-friendly text editor. The codebase prizes simplicity and portability, making it feasible to build and run on a variety of Unix-like systems without heavyweight dependencies. Its feature set is deliberately modest compared to full Emacs, favoring a quick, predictable editing experience for everyday text manipulation. The project serves as both a functional tool and an example of clean, old-school C systems programming. Because the editor is small, users can understand and modify it more easily than sprawling IDEs, which is appealing for hacking and learning. It’s not meant to compete with modern extensible editors; it exists as a minimal, dependable workhorse that starts fast and stays out of the way. -

ui-box
Blazing Fast React UI Primitive
ui-box is a low-level React UI primitive library that provides a simple and performant way to build styled components using a CSS-in-JS approach. Instead of relying on traditional CSS files or complex styling systems, ui-box allows developers to apply CSS properties directly through React props, making styling more intuitive and composable. The core concept revolves around a single Box component that can render different HTML elements while accepting a wide range of style-related properties. This approach enables developers to create reusable components without needing additional wrapper elements or class-based styling, improving both readability and maintainability. The library is designed to be fast and extensible, focusing on minimal overhead while still offering powerful styling capabilities. It also supports advanced features such as pseudo-selectors and conditional styling through prop-based configurations. ui-box serves as the foundational layer for more complex UI systems. -

vue-datatables-net
Vue jQuery DataTables.net wrapper component
This library is a Vue 3 wrapper for jQuery DataTables. It's a tiny wrapper that doesn't include anything, not even the datatables.net core library. You've found this library because you want to use jQuery datatables.net client-side with your application. Alternatively, if you simply want to integrate with a server-side datatables.net compatible endpoint, then I'd like to suggest looking at bootstrap-vue b-table and this component. Default configuration and provide an example for bootstrap5 styling. Though, it allows for complete flexibility of customization with any other jQuery DataTables-supported theme. -

waybackurls
Fetch all the URLs that the Wayback Machine knows about for a domain
waybackurls is a command-line reconnaissance tool that retrieves historical URLs associated with a given domain by querying the Internet Archive’s Wayback Machine. It accepts input domains via standard input and outputs a list of discovered URLs, making it easy to integrate into pipelines and automated workflows. The tool is particularly valuable in security research, bug bounty hunting, and penetration testing, as it uncovers endpoints that may no longer be publicly linked but still exist on servers. By leveraging archived data, waybackurls helps identify hidden attack surfaces, legacy APIs, and forgotten resources that could be vulnerable. Its design is intentionally simple and efficient, focusing on delivering large volumes of URLs quickly with minimal configuration. The output can be combined with other tools for further analysis, such as filtering parameters or probing endpoints. -

SimpleXlsxWriter
C++ library for creating XLSX files for MS Excel 2007 and above.
This library represents XLSX files writer for Microsoft Excel 2007 and above. The main feature of this library is that it uses C++ standard file streams. On the one hand it results in almost unnoticeable memory and CPU resources consumption while processing (that may be very useful at saving a large data arrays), but on the other hand it makes unfeasible to edit data that were written. Hence, if using this library the structure of the future report should be known enough. The library is written in C++ with using STL functionality and based on the ZIP library (included), which has a free license: http://www.codeproject.com/Articles/7530/Zip-Utils-clean-elegant-simple-C-Win32 This library is distributed under the terms of the zlib license: http://www.zlib.net/zlib_license.html -
