RTree - Hyper-Dimensional R-Tree Index in Java
An index that supports building a tree of bounding rectangles for arbitrary range searches. RTrees are efficient for geospatial data but can be extended to support any data that is amenable to range searching.

Conversant RTree is a hyper-dimensional (2D, 3D, 4D, nD) implementation of RTrees in Java. Conversant RTree supports data with large numbers of orthogonal relations or high dimensionality in the same way that traditional RTrees support 2 or 3 dimensional spatial data.

Rogue - SSR (Server-Side Rendering) for React
SSR for React that's invisible (zero configuration!) and quick (no Webpack!).
With Rogue, the SSR configuration will be nearly invisible to you. You don't need a special /pages directory (like Nextjs) or a separate routes.js file (like Afterjs). All you need is the App.js entry point you'd usually have. This means that you can wrap your app in layouts/transitions/providers, etc. the same way you would in a regular React Application, and staying true to React's values, you can organize your code however you like.

Functional Data Structures
This flânerie is a stroll through intermediate data structures and their associated algorithms, from the point of view of functional programming. In brief: we wish to manipulate data in various ways, to extract information or to store information for later retrieval. We want these operations to be efficient in their use of resources (chiefly time and space). The data may be naturally structured, or we may impose structure on it for the sake of efficiency.
