This repository is a comprehensive collection of data structures and algorithms implemented in JavaScript, designed primarily as an educational resource for computer science study and technical interview preparation. It provides modular implementations of fundamental programming concepts, allowing developers to explore algorithmic logic and data organization through self-contained, verifiable code examples. The library distinguishes itself by pairing every implementation with formal Big O notation, providing predictable insights into time and space scaling requirements. Each algorithm is stru

Relativ is an open-source project for the development of custom virtual reality hardware, encompassing the mechanical design, electronics, and software interfaces required to build a headset from scratch. It provides the frameworks necessary for assembling devices using open-source electronics and firmware. The project integrates custom hardware with SteamVR through driver-based configurations, mapping device identifiers and display viewports to ensure rendered images align with physical secondary displays. It employs a combination of microcontroller-based inertial measurement unit polling fo

dnsguide is a software implementation of the DNS protocol designed to handle queries and responses between clients and nameservers. It functions as a recursive DNS server and network service tool for managing the resolution of domain names within local or wide area networks. The project provides a framework for building a custom DNS server, incorporating recursive resolution logic and stub resolver integration to translate hostnames into IP addresses. It is designed for implementing the DNS protocol from scratch to facilitate network protocol learning and custom name resolution. The implemen

This project is a pedagogical implementation of a hash table in C, built from scratch using open addressing and linear probing for collision resolution. It serves as a computer science algorithm demo, demonstrating how to construct a fundamental key-value store at a low level. The implementation covers the core operations of an associative array: inserting a key-value pair, looking up a value by its key, and deleting a pair. It uses a hash function to compute storage locations, maps hash values to array indices with the modulo operator, and resolves collisions by scanning sequentially through
