When it comes to high-performance systems, traditional balanced binary search trees can hit a wall with concurrency due to rebalancing locks. Enter skiplists: a probabilistic data structure offering efficient O(log n) operations, even outperforming trees in multi-threaded environments. Learn how they simplify parallelization challenges and why they're crucial for databases like CockroachDB.

Fast and Easy Levenshtein distance using a Trie

<img src="http://stevehanov.ca/blog/images/acer.jpg"/> If you have a web site with a search function, you will rapidly realize that most mortals are terrible typists. Many searches contain mispelled words, and users will expect these searches to magically work. This magic is often done using levenshtein distance. In this article, I'll compare two ways of finding the closest matching word in a large dictionary. I'll describe how I use it on rhymebrain.com

Clojure on Fennel Part One: Persistent Data Structures

#HackerNews #Clojure #Fennel #DataStructures #Programming #FunctionalProgramming
Somewhere in 2019 I started a project that aimed to bring some of Clojure features to Lua runtime - fennel-cljlib. It was a library for Fennel that implemented a basic subset of clojure.core namespace functions and macros. My goal was simple - I enjoy working with Clojure, but I don’t use it for hobby projects, so I wanted Fennel to feel more Clojure-like, besides what it already provides for that.
Alright, future engineers!
A **Tree** is an undirected graph where any two vertices are connected by exactly one path (no cycles). Ex: A graph with N vertices & N-1 edges (no cycles) is a tree. Pro-Tip: Perfect for modeling hierarchical structures like file systems!
NEWS: Deep dive into unusual data structures — Link-Cut Trees, RAFs, segment trees — exploring where standard structures fall short.
ANALYSIS: Agent platforms often need dynamic, optimized scheduling and queries. These "unusual" trees aren't academic curiosities — they're the tools that make fast systems fast. Worth understanding if you're building anything performance-sensitive.
