What It Is

4r7.com “思若起” is a Chinese personal independent blog with a site name that carries a strong sense of personal expression. Based on the page information, the blog mainly focuses on computer science, algorithms, programming practice, and records of things the blogger finds interesting. The site has migrated to WordPress and switched to the 4r7.com domain in 2023. It is a typical long-running personal blog rather than a commercial product or large content platform.

Core Features

The site offers an article list, categories, tags, archives, RSS subscription, comments, and a blogroll page. Its content includes technical articles such as LeetCode algorithm solutions, the Tribonacci sequence, finding peak elements, configuring FFmpeg and Pydub on Mac M1, and a full-stack Java Spring knowledge system. It also contains poetry excerpts, life records, and personal reflections. Overall, it is positioned more like a “personal knowledge and life-fragment repository.”

Pricing

The site’s content is publicly accessible for free. The collected content does not show any membership system, paid courses, ad monetization, sponsored subscriptions, or e-commerce transactions. Its main value lies not in transactions or services, but in free reading and communication.

Pros and Cons

Its strengths are that the content feels authentic and shows traces of continuous personal documentation. It also preserves traditional independent-blog features such as RSS, comments, and blogroll links. The technical topics cover algorithms, Python, Java, front-end/back-end development, and tool configuration, offering some reference value for beginners looking up practical experience. The drawbacks are also clear: the number of articles is not large, category depth is limited, and some content leans toward personal notes, making it less systematic than professional tutorial sites. At the same time, it is not a community platform, so its interaction scale and support capacity are limited.

Who It’s For

It is suitable for readers who like Chinese independent blogs, want to read personal technical learning notes, reference algorithm solutions, or find similar blogroll sites. If users need structured courses, enterprise-level technical documentation, or frequently updated news, CSDN, Juejin, Blog Garden, or official documentation would be more appropriate.

Access in China

The page indicates that the server was once moved to the East China Shanghai region, and the content is a Chinese personal blog, so access from mainland China should generally be direct. Overall rating: 6/10. As a personal blog, it has character and warmth, but as a public resource repository, its scale and professional completeness remain limited.
