    Icon Font to PNG

    Icon Font to PNG

    Python script (and library) for exporting icons from icon fonts

    Python script (and library) for easy and simple export of icons from web icon fonts (e.g. Font Awesome, Octicons) as PNG images. The best part is the provided shell script, but you can also use it’s functionality directly in your (probably awesome) Python project. There’s also font-awesome-to-png script for backward compatibility with the first iteration of the concept. You can use IconFont (and IconFontDownloader for that matter) directly inside your Python project. There's no proper documentation as of now, but the code is commented and should be pretty straightforward to use.

    Idiomatic CSS

    Idiomatic CSS

    Principles of writing consistent, idiomatic CSS

    Idiomatic CSS is a widely referenced style guide for writing clean, consistent, and maintainable CSS. It lays out naming patterns, file organization, and comment conventions so teams can collaborate without tripping over different styles or habits. The guide emphasizes clarity over cleverness, encouraging predictable selectors and practical class names that scale as a codebase grows. It also discusses how to structure rules, whitespace, and property ordering to make diffs cleaner and reviews faster. Beyond formatting, it promotes a mindset of thoughtful abstraction and restraint, helping developers avoid premature complexity. Because it is tool-agnostic, the advice applies whether you use vanilla CSS, preprocessors, or utility systems, and it can be adapted to fit most workflows and build pipelines.

    Idiomatic.js

    Idiomatic.js

    Principles of Writing Consistent, Idiomatic JavaScript

    idiomatic.js is a style guide repository that defines conventions and best practices for writing clean, readable, and maintainable JavaScript code, largely serving as a reference for developers to ensure consistency across projects. It lays out guidelines for topics such as formatting, naming, control structures, modularity, and language features, helping teams avoid common pitfalls and style disagreements. The guide includes examples of both recommended and discouraged patterns, making it easier to understand why a particular convention exists, not just what it is. Because JavaScript has many ways to express the same logic, idiomatic.js aims to narrow the surface of healthy patterns so collaborative projects can stay easy to read and review over time. Many community projects and companies adopt the guide wholesale or adapt it for their coding standards, which helps streamline onboarding and maintain code quality.

    Image Select

    Image Select

    Image Select is an extension of Chosen, a jQuery plugin

    We designed this plugin extension as a humanized UI element for social networking sites that need to facilitate relations between people. Research shows that people are extremely sensitive to photos of others, so we needed to revamp the traditional UI elements to make them more intuitive and human. You can use these plugin extensions for modeling multiple (one-to-many) or single (one-to-one) relations between people. We couldn't find any scripts that had this full functionality, so we developed it ourselves on top of Chosen. Hope you find it helpful, and get back if you have any feedback/improvements.

    Images.jl

    Images.jl

    An image library for Julia

    JuliaImages (source code) hosts the major Julia packages for image processing. Julia is well-suited to image processing because it is a modern and elegant high-level language that is a pleasure to use, while also allowing you to write "inner loops" that compile to efficient machine code (i.e., it is as fast as C). Julia supports multithreading and, through add-on packages, GPU processing. JuliaImages is a collection of packages specifically focused on image processing. It is not yet as complete as some toolkits for other programming languages, but it has many useful algorithms. It is focused on clean architecture and is designed to unify "machine vision" and "biomedical 3d image processing" communities.

    Incremental DOM

    Incremental DOM

    An in-place DOM diffing library

    Incremental DOM is a lightweight library for building DOM trees by issuing imperative update instructions, avoiding heavyweight virtual DOM diffing at runtime. Instead of creating and diffing large object graphs, templates compile to a sequence of function calls that “patch” the live DOM in place. This model eliminates allocations associated with virtual trees and allows updates to be streamed directly to the DOM, which can improve memory usage and reduce GC pressure. It integrates naturally with template compilers (such as those that generate calls from HTML-like markup) but can also be used by hand for fine-tuned rendering. The library is small and focused: it manages element creation, attribute updates, and text nodes while leaving state management and data flow to the host framework. The result is predictable updates with minimal overhead, especially useful in performance-critical views.

    Infosec Reference

    Infosec Reference

    An Information Security Reference That Doesn't Suck

    Infosec Reference is a curated knowledge base and resource repository for information security practitioners. It aggregates cheat sheets, tooling guides, protocol deep dives, incident response playbooks, and threat actor profiles—all organized under accessible categories (network, web, host, cryptography, auditing). The repo is built as a living wiki of sorts: practitioners contribute updates, expand sections, or refine explanations as the threat landscape evolves. Because security spans many domains, Infosec Reference helps consolidate high-value, battle-tested knowledge into one place, reducing the need to scour scattered blogs or notes. It often contains links to external references, example commands, common workflows, and template policies or checklists. For newer security professionals or teams looking to build a shared reference, it serves as a catalog of contextually verified insights, a starting point for training, or a hub for standardized practices.

    Inject

    Inject

    Hot Reloading for Swift applications

    Hot reloading workflow helper that enables you to save hours of time each week, regardless if you are using UIKit, AppKit or SwiftUI. Hot reloading is a technique allowing you to get rid of compiling your whole application and avoiding deploy/restart cycles as much as possible, all while allowing you to edit your running application code and see changes reflected as close as possible to real-time. This makes you significantly more productive by reducing the time you spend waiting for apps to rebuild, restart, re-navigate to the previous location where you were in the app itself, re-produce the data you need. You don’t need to add conditional compilation or remove Inject code from your applications for production, it's already designed to behave as no-op inlined code that will get stripped by LLVM in non-debug builds.

    Integrant

    Integrant

    Micro-framework for data-driven architecture

    Integrant is a minimalistic micro-framework for building applications following a data-driven architecture. It lets you define system components declaratively as configuration data and handles lifecycle actions (init, halt, resume) in dependency order, serving as a modern alternative to Component or Mount. Integrant was built as a reaction to fix some perceived weaknesses with Component. In Component, systems are created programmatically. Constructor functions are used to build records, which are then assembled into systems. In Integrant, systems are created from a configuration data structure, typically loaded from an edn resource. The architecture of the application is defined through data, rather than code.

    Library for validated numerics using interval arithmetic

    IntervalArithmetic.jl is a Julia package for validated numerics in Julia. All calculations are carried out using interval arithmetic where quantities are treated as intervals. The final result is a rigorous enclosure of the true value. We are working towards having the IntervalArithmetic library be conformant with the IEEE 1788-2015 Standard for Interval Arithmetic. To do so, we have incorporated tests from the ITF1788 test suite.

    Introduction to Programming Principles

    Introduction to Programming Principles

    Categorized overview of Programming Principles & Patterns

    Introduction to Programming Principles is a living catalog of fundamental software development principles collected in one place so developers can reference and teach them easily. It documents well-known concepts like SOLID, DRY, KISS, YAGNI, and others, and explains when and why to apply them. The goal is to move principles from being fuzzy tribal knowledge to explicit, written, teachable guidelines. Because it’s on GitHub, it can evolve as the community suggests new principles, clarifications, and real-world examples. The repository is especially useful for onboarding junior developers or creating internal engineering handbooks. It also serves as a companion to code-quality projects by giving the “why” behind refactoring and architectural choices.
