This small gem contains several data structures that I have implemented in Ruby to learn how they work. Sometimes it is not enough to read the description of a data structure and accompanying pseudo-code. Actually implementing it is often helpful in understanding what is going on. It is also usually fun. The gem contains basic implementions of Disjoint Union, Heap, Priority Search Tree, and Segment Tree. See the homepage for more details.

HeapPeriscopeUi is a Rails engine designed to help developers monitor, visualize, and diagnose memory-related issues within their Ruby applications. It functions by listening for UDP packets containing GC profiler reports and heap snapshots, typically transmitted by a companion agent (like `heap_periscope_agent`). The engine efficiently processes this data: GC reports are batched for optimized database insertion, while comprehensive heap snapshots, including detailed object counts by class, are stored transactionally. Furthermore, HeapPeriscopeUi can broadcast incoming metrics via ActionCable for real-time dashboard updates. Its integrated web interface allows users to browse, filter, and analyze the collected profiler reports, facilitating the identification of memory leaks, excessive object allocations, and opportunities for performance optimization.

Heap Periscope Agent offers deep insights into your Ruby application's memory behavior. It collects and reports real-time Garbage Collection (GC) statistics and object allocation patterns, empowering developers to identify memory leaks, optimize usage, and enhance performance. Highly configurable and designed for minimal overhead.
