aalansehaiyang/technology-talk

technology-talk is a Chinese-language technical guide for Java programmers, framed as a study companion for interviews at large tech companies. It is maintained by an author who goes by Tom Ge and describes himself as an Alibaba P7 technical expert with offers from companies like Baidu, Huawei, and Tencent. The repository points readers to a website called offercome.cn for the best reading experience, and it advertises a paid knowledge community as well. The first major section is a 20-part interview series. Each part is a long article in Chinese covering a specific area: Java basics like reflection and generics, Java collections, concurrency, the JVM, system architecture, the interview process itself, Redis, MySQL, Mybatis, Spring, Spring Boot, Spring Cloud, message queues, Kafka, RocketMQ, TCP networking, operating systems, Docker, Kubernetes, and Nginx. Each entry promises common interview questions and the deeper concepts behind them. The second section is a paid interview-skills course. It walks through topics like which channels to use to find work, how to pick a company, how to read a job description, when to switch jobs, how to write a resume that stands out, how to handle questions you cannot answer, what HR typically asks, how to choose between multiple offers, and how to negotiate a higher salary. The rest of the README is a long index of articles on specific middleware and frameworks. Redis articles cover cache design at hundred-million-user scale, bloom filters, why Redis Cluster uses 16384 slots, master failover, data skew, and common usage scenarios. MySQL articles cover B+ tree storage, slow queries that hit indexes, row and gap locks, binlog, and master-replica delay. There are also sections on message queues (Kafka, RocketMQ, RabbitMQ), Spring, Spring Boot integration with libraries like Druid, ShardingSphere, Caffeine, ElasticSearch, Pulsar, Apollo, Nacos, and MongoDB. For a non-technical reader, this repository is best understood as a curated reading list aimed at people preparing for Java backend interviews in the Chinese market. It contains no code to run, only links to articles. Many links go to docs/md/ files inside the repo, while others lead to the author's website or WeChat articles, some behind a paywall.
