rbush - RBush — a high-performance JavaScript R-tree-based 2D spatial index for points and rectangles

  •    Javascript

RBush is a high-performance JavaScript library for 2D spatial indexing of points and rectangles. It's based on an optimized R-tree data structure with bulk insertion support. Spatial index is a special data structure for points and rectangles that allows you to perform queries like "all items within this bounding box" very efficiently (e.g. hundreds of times faster than looping over all items). It's most commonly used in maps and data visualizations.

Pilosa - Distributed bitmap index that dramatically accelerates queries across multiple, massive data sets

  •    Go

Pilosa is an open source, distributed bitmap index that dramatically accelerates continuous analysis across multiple, massive data sets. Pilosa collapses the speed and batch layer by abstracting the index from data storage, optimizing it for massive scale, and making your data instantly queryable and continuously analyzable.

  •    Javascript

I don't have enough time to maintain this plugin as I would want to, so I'm looking for people who want to help out and be contributors/repository admins. Contact me! See package.json for contact information.




speedline - Calculate the speed index and visual performance metrics from chrome dev tool timeline (recently: pmdartus -> paulirish)

  •    Javascript

The Navigation Timing API provides useful data that can be used to measure the performance of a website. Unfortunately this API has never been good at capturing the actual user experience. The Speed Index, introduced by WebpageTest.org, aims to solve this issue. It measures how fast the page content is visually displayed. The current implementation is based on the Visual Progress from Video Capture calculation method described on the Speed Index page. The visual progress is calculated by comparing the distance between the histogram of the current frame and the final frame.

World Index

  •    Silverlight

The World Index project is a Silverlight project that is built to expose UN Millenium development goals using their public available data as datasource. The World Index project is based on the modules so it can be extended with other country based data.

negative-array - Negative array index support `array[-1]` using ES2015 Proxy

  •    Javascript

JavaScript doesn't natively support the use of a negative index to get items backwards from the end, but with ES2015 Proxy it's possible. Take a look at the source to see how simple it is to implement and read this short article about it.Proxies are objects for which the programmer has to define the semantics in JavaScript. The default object semantics are implemented in the JavaScript engine, often written in lower-level languages like C++. Proxies let the programmer define most of the behavior of an object in JavaScript. They are said to provide a meta-programming API.

hypopg - Hypothetical Indexes for PostgreSQL

  •    C

HypoPG is a PostgreSQL extension adding support for hypothetical indexes. An hypothetical, or virtual, index is an index that doesn't really exists, and thus doesn't cost CPU, disk or any resource to create. They're useful to know if specific indexes can increase performance for problematic queries, since you can know if PostgreSQL will use these indexes or not without having to spend resources to create them. For more information on this extension usage, you can see this blog post.

flatbush - A very fast static spatial index for 2D points and rectangles in JavaScript

  •    Javascript

A really fast static spatial index for 2D points and rectangles in JavaScript. An efficient implementation of the packed Hilbert R-tree algorithm. Enables fast spatial queries on a very large number of objects (e.g. millions), which is very useful in maps, data visualizations and computational geometry algorithms.
