beautiful-html-templates
A library of HTML slide templates
beautiful-html-templates is a reusable library of HTML slide templates made for coding agents that need to produce polished presentation decks automatically. It gives agents a structured way to choose a visual direction, clone the right template, and adapt it to a user’s content brief. The project includes an index-driven workflow, with guidance files that explain how an agent should inspect available templates and match them to the requested style. Its templates are intended to be practical starting points rather than generic blank layouts. The library is useful for AI-assisted deck creation, branded one-off presentations, and fast visual prototyping. Its main value is helping agents create attractive HTML-based slides without designing every layout from scratch. -

AngularJS
AngularJS - HTML enhanced for web apps
AngularJS is a discontinued, open-source JavaScript framework by Google designed to extend HTML for building powerful single-page applications using MVC or MVVM patterns, offering data binding, dependency injection, and testability to simplify development. AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade/Pug and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding. To help you structure your application better and make it easy to test, AngularJS teaches the browser how to do dependency injection and inversion of control. -

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. -

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. -

'brunch new' to create a new project. 'brunch build' to build. 'brunch watch' to live-compile. Installation is one-line, once you have node.js. You will find that the typical config of a Brunch application is an order of magnitude simpler, compared to Webpack, Grunt, or Gulp. Besides configs, brunch is also simpler in terms of commands. Grunt / Gulp commands replicate all plugins it loads. Brunch always has three commands: new, build and watch. Build / watch commands may receive optional production flag which will tell Brunch to optimize assets, javascripts and stylesheets. -

Stylus - Userstyles Manager
Stylus is a fork of Stylish for Chrome, also compatible with Firefox as a WebExtension. "Stylus" is a fork of the popular Stylish extension which can be used to restyle the web. Not "ish", but "us", as in "us" the actual users. Stylus is a fork of Stylish that is based on the source code of version 1.5.2, which was the most up-to-date version before the original developer stopped working on the project. The objective in creating Stylus was to remove any and all analytics, and return to a more user-friendly UI. We recognize that the ability to transfer your database from Stylish is important, so this is the one and only feature we've implemented from the new version. Two different optional code validators with user-configurable rules: CSSLint and Stylelint. Both validators use Web Worker API to run in a separate background thread inside the editor tab without blocking your interaction with the code. -

V Programming Language
Simple, fast, safe, compiled language for developing software
Simple language for building maintainable programs. You can learn the entire language by going through the documentation over a weekend, and in most cases, there's only one way to do something. This results in simple, readable, and maintainable code. Despite being simple, V gives a lot of power to the developer and can be used in pretty much every field, including systems programming, webdev, gamedev, GUI, mobile, science, embedded, tooling, etc. V avoids doing unnecessary allocations in the first place by using value types, and string buffers, promoting a simple abstraction-free code style. Most objects (~90-100%) are freed by V's auto-free engine: the compiler inserts necessary free calls automatically during compilation. A remaining small percentage of objects is freed via GC. The developer doesn't need to change anything in their code. "It just works", like in Python, Go, or Java, except there's no heavy GC tracing everything or expensive RC for each object. -
