Frevo
Frevo is probably the simplest tool for evolutionary design
FREVO is an open-source framework developed in Java to help engineers and scientists in evolutionary design or optimization tasks. The major feature of FREVO is the componentwise decomposition and separation of the key building blocks for each optimization tasks. We identify these as the problem definition, solution representation and the optimization method. This structure enables the components to be designed separately allowing the user to easily swap and evaluate different configurations and methods or to connect an external simulation tool. The latest version in development is hosted at https://github.com/smartgrids-aau/Frevo -

FriendlyId
FriendlyId is the “Swiss Army bulldozer” of slugging
FriendlyId is a Rails gem that provides human-readable slugs for ActiveRecord models, replacing numeric IDs in URLs with meaningful strings. For example, instead of /articles/123, you can have /articles/my-first-post. It integrates with ActiveRecord to generate slugs automatically based on attributes (like a title) and manages uniqueness, history, and slug regeneration when records change. FriendlyId also supports features like slug candidates, scoped slugs, and reserved word handling to avoid conflicts. It includes extensions to keep old slugs working as redirects, so links don’t break when content is renamed. By improving readability, SEO, and user-friendliness, FriendlyId has become the de facto solution for slugging in Rails applications. -

From Java To Kotlin
Your Cheat Sheet For Java To Kotlin
From Java to Kotlin is a practical guide for Android developers transitioning existing codebases and habits from Java to idiomatic Kotlin. Rather than simply showing syntax translations, it emphasizes Kotlin’s expressive features—null safety, extensions, data classes, sealed hierarchies, and higher-order functions—and how to apply them sensibly. Examples illustrate side-by-side Java and Kotlin snippets, revealing opportunities to reduce boilerplate and improve readability. The guide includes best practices for coroutine usage, collection operations, and scoping functions that make asynchronous and functional patterns feel natural. It also discusses interoperability and migration strategies so mixed-language projects remain stable during the transition. The result is a concise playbook that helps teams adopt Kotlin with confidence, writing safer and more maintainable code without losing touch with the underlying platform. -

GDAL.jl
Thin Julia wrapper for GDAL - Geospatial Data Abstraction Library
Julia wrapper for GDAL - Geospatial Data Abstraction Library. This package is a binding to the C API of GDAL/OGR. It provides only a C style usage, where resources must be closed manually, and datasets are pointers. Other packages can build on top of this to provide a more Julian user experience. See for example ArchGDAL.jl. Most users will want to use ArchGDAL.jl instead of using GDAL.jl directly. -

GLM.jl
Generalized linear models in Julia
GLM.jl is a Julia package for fitting linear and generalized linear models (GLMs) with a syntax and functionality familiar to users of R or other statistical environments. It is part of the JuliaStats ecosystem and is tightly integrated with StatsModels.jl for formula handling, and Distributions.jl for specifying error families. The package supports modeling through both formula-based (e.g. @formula) and matrix-based interfaces, allowing both high-level convenience and low-level control. Under the hood, GLM.jl separates the linear predictor and response objects, allowing flexible combinations of link functions, variance structures, and fitting methods. -

GLSlayer
An object oriented 3D graphics API on top of OpenGL
This project has moved to GitHub: https://github.com/ubershader/GLSlayer OpenGL Sanity Layer is an object-oriented 3D graphics API on top of OpenGL written in C++. It is designed not just to provide an encapsulation of OpenGL objects, but to provide a cleaner and more streamlined interface similar to Direct3D and hide some of OpenGL's weak spots such as bind-to-edit semantics, multiple stage object creation, unavailability of platform independent initialization and loading of extensions to expose features. With GLSlayer it is easy to create a rendering context just by filling a structure and calling a function. All extensions needed to expose features for requested OpenGL version are loaded automatically. The code needed to create, setup and use objects is reduced and made intuitive. It supports OpenGL versions from 3.3 to 4.3, only forward compatible contexts. -
