It feels good to be back, reflecting, pondering, and putting thoughts into words. Let's talk about something core to the software engineering that often gets overlooked in the rush to code: d...

1. BFS using Queue Just in the prior post on graph traversal, we went into details of Depth-First Search (DFS) and Breadth-First Search (BFS). BFS is a way of traversing down the graph, level-by-...

0. Graph Traversal Breadth-First Search (BFS) and Depth-First Search (DFS) are two of the most commonly used graph traversal methods. The traversal of a graph, whether BFS or DFS, involves two ma...

Before heading into details of how we store, represent, and traverse various kinds of graphs, this post is more of a ramp-up to better understand what graphs are and the different kinds from a co...

If you have been following the Spatial Index Series, it started with the need for multi-dimensional indexes and an introduction to space-filling curves, followed by a deep dive into grid systems ...

Brewing! this post a continuation of Spatial Index: Grid Systems where we will set the foundation for tessellation and delve into the details of Uber H3 0. Foundation Tessellation or tiling is t...

This post is a continuation of Stomping Grounds: Spatial Indexes, but don’t worry if you missed the first part—you’ll still find plenty of new insights right here. 3. Geohash Geohash: Invented ...

0. Overview Spatial data has grown (/is growing) rapidly thanks to web services tracking where and when users do things. Most applications add location tags and often allow users check in specifi...
