CppGuide is a curated collection of educational resources and practical guides focused on C++ server development, Linux kernel internals, concurrent programming, network protocols, and security exploitation. It provides structured learning paths for backend developers, covering everything from interview preparation to building high-performance network servers and understanding operating system fundamentals. The guide distinguishes itself by offering in-depth, hands-on tutorials that walk through real-world implementations, including building a Redis-like server from scratch, designing custom

RoaringBitmap is a Java-based library designed for the memory-efficient storage and high-speed querying of large sets of integers. It functions as an in-memory analytics tool that maintains compact data representations while supporting rapid set calculations, such as intersections, unions, and differences. The library distinguishes itself through a hybrid compression strategy that automatically selects between bitsets, sorted arrays, or run-length encoding based on the density of the data. It utilizes a two-level hierarchical index to provide constant-time random access lookups, ensuring perf
