Course Introduction：Lock-Free data structures enable thread safety through atomic operations and CAS, rather than traditional blocking locks. Its core lies in lock-free but orderly, relies on CPU instructions such as CAS and FAA, and is implemented using Java's atomic package class, which is suitable for high concurrency scenarios such as queues, counters, etc. When implementing, you need to pay attention to ABA issues, memory order, loop retry overhead and debugging difficulty. Practical steps include familiarizing yourself with atomic classes, learning CAS principles, reading open source code, small-scale experiments and multi-test verification.

Course Introduction：Choosing Monorepo can improve multi-project collaboration efficiency and code sharing. Nx is more suitable for building medium and large systems from scratch, providing intelligent task scheduling, rich plug-in ecosystem and IDE integration; Lerna is good at NPM package management, and is suitable for existing build systems or open source projects. Both can also be used in combination. In practice, Nx can initialize and add plug-in to generate projects through create-nx-workspace; Lerna needs to set workspaces and use lernacreate to create packages, and select the appropriate version strategy.

Course Introduction：The most effective way to learn C is to learn while doing the actual project. ① Start practicing with simple projects, such as calculators, file encryption tools, student information management systems, contact basic grammar and hands-on practice; ② Learn to use object-oriented and STL libraries, try to encapsulate logic with classes, and be familiar with common components such as vectors, maps, and fstream; ③ Challenge more complex projects, such as online chat rooms, mini games, thread pools, and contact advanced topics such as multi-threading, network communications; ④ Use open source projects and community resources to make continuous progress, debug more, check documents, and ask questions, and insist on writing code to accumulate practical experience.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
