CrazyJums (jums.club) is the personal tech blog of “小朱同学.” The site lists around 259 posts and 71 tags, covering topics such as Git, Go, PHP, Java, WebSocket, Linux, MySQL, Redis, Docker, AI/ChatGPT, and more. It is closer to a programmer’s personal knowledge base and collection of practical notes than a commercial product or online course platform.
The site offers a homepage article feed, archives, tags, LeetCode, comments, Kbooks, friend links, media, and an about page, along with local search. Most posts focus on problems encountered during development and their solutions, such as syncing a forked repository, pulling dependencies from private Go repositories, WebSocket fundamentals, APCu caching, and ChatGPT registration tutorials. The about page also includes the author’s resume, project experience, and tech stack, giving the site a personal branding element.
The currently crawled content does not show paid subscriptions, memberships, or courses for sale, so the articles appear to be free to read. There is a Donate section in the footer, with wechat, alipay, and bitcoin listed, indicating support for voluntary tips via WeChat, Alipay, and Bitcoin.
The main advantages are its straightforward Chinese-language content and engineering-oriented articles, making it useful for quickly looking up specific development issues. The tags and archives are fairly complete, which makes it easy to browse older notes. The author has a backend development background, and some project retrospectives and performance optimization write-ups offer real-world reference value.
The downsides are also typical of personal blogs: article quality and depth are not fully consistent, and some posts are short or lean toward reposted/compiled content. It lacks a systematic course structure, so it is not suitable as the sole resource for learning a technology from scratch. Judging from the archives, the maintenance frequency is not especially high, and its comments and support cannot compare with larger communities.
It is suitable for junior to mid-level backend developers, computer science students, interview candidates, and users who want Chinese experience-based posts when troubleshooting specific issues related to Git, Go, WebSocket, PHP, caching, databases, and similar topics. If you need authoritative specifications, it is still best to read it alongside official documentation.
The domain is a personal site, the content is in Chinese, and there is no apparent requirement to log in or depend on overseas services, so it is likely directly accessible from mainland China. However, external links such as GitHub, OpenAI, and some cryptocurrency or SMS platform resources may be unstable to access from China or may require additional network conditions.
