selfboot.cn, with the site name Just For Fun, is a personal technical blog maintained by the author SelfBoot. The site is built with Hexo and uses the SelfBoot theme. Its core focus is sharing technical knowledge rather than serving as a commercial product. The collected content shows that the site has been regularly updated over time with articles on programming, source code analysis, computer science fundamentals, artificial intelligence, tool introductions, and more. Recent content focuses mainly on reading the LevelDB source code and analyzing C++ engineering issues.
The site’s main functions are article publishing, category archives, tag indexing, and personal project showcases. The content leans toward in-depth engineering practice, covering implementation details such as LevelDB’s SSTable, DataBlock, LRU Cache, MVCC, as well as real-world cases involving C++ process crashes, coredumps, iterator invalidation, and concurrent data races. It also includes hands-on experiences with AI tools such as ChatGPT, Claude, Cursor, and MCP Server, offering useful reference value for developers.
It currently appears to follow a free-to-read model. The articles do not show any membership system, course sales, or subscription paywall; only sponsorship prompts, WeChat public account syndication, and legal consultation ads appear. As such, it is more like an open personal knowledge base than a paid education product.
The strengths are that the articles clearly reflect frontline engineering experience, with concrete cases, solid code examples, and practical troubleshooting approaches. Categories, archives, and tags are clearly organized, making it suitable for topic-based browsing. The source code analysis series is updated continuously and works well for advanced readers who want to follow along. The drawbacks are also clear: as a personal blog, it lacks a systematic learning path, and the scope of content depends on the author’s interests. Some articles have a relatively high barrier to entry, so beginners may need additional background knowledge. Comments use Disqus, which is usually unstable to access from mainland China.
It is suitable for backend developers, C/C++ programmers, learners of databases and storage systems, computer science students, and people interested in the real-world use of AI programming tools. It is less suitable for users looking for beginner-friendly courses, homework grading, or a certificate-based learning system.
The main site uses a .cn domain, so the article content should generally be directly accessible. However, comments rely on Disqus, and some external links such as GitHub and Google-related resources may be affected by the network environment. Overall, access can be considered “partially restricted.”
