🕹 Technology Data Structures WebAssembly Image Processing
  1. Quadtrees are data structures where each non-leaf node has exactly four children and are used to represent properties of two-dimensional space.
  2. Quadtrees are used for performance reasons, like optimizing collision detection in simulations with many moving objects.
  3. Implementing region quadtrees in Rust involves subdividing the tree based on error thresholds and region lengths to efficiently represent images.

Exploring beautiful code

14 implied HN points • 10 Mar 22
  1. The newsletter explores big ideas behind beautiful libraries, systems, and applications.
  2. It helps capture the essence, rationale, and trade-offs of existing software.
  3. By building prototypes and understanding the landscape, it aims to assist in making good choices in programming.

Property-based testing #1: What is it anyway?

1 HN point • 01 May 22
  1. Property-based testing relates input and output by asserting general properties on automatically generated inputs.
  2. There are different strategies for generating values in property-based testing, like pseudo-random generation, exhaustive generation, and optimization-guided generation.
  3. Property-based testing libraries provide tools for writing value generators, running tests, and shrinking failing values to aid in debugging.
