hhacker.com, whose site name is “奇怪的刘日天,” appears from the crawled content to be a Chinese personal blog with a WordPress-style feel, rather than a commercial SaaS product, hosting service, or developer tool platform. The site has long documented the author’s technical experiments, indie product experience, AI app development, indie game development, Linux operations, DNS/DoH configuration, and yearly reflections. Its core value lies in accumulated personal experience, with content closer to a personal column within the developer community.
The site’s main function is publishing and reading articles. Representative posts include “How to Make Users Willingly Pay: Indie Product Experience,” “The Full Process of Building My First AI App,” “Building an Indie Game from Scratch and Launching It on Steam,” “Investigating a Linux OOM Incident,” “Setting Up a Clean DNS Service,” and “Enabling DNS Encryption in Win11.” Some technical articles include command-line usage, configuration steps, Cloudflare Workers code, DNS forwarding approaches, and other highly practical details.
The crawled content does not show any membership system, paywall, course sales, or subscription plans, and the articles appear to be freely accessible. The site is also not primarily focused on selling a specific piece of software or service, so its pricing model should be considered free reading.
The strengths are that the content feels authentic and grounded in real practice, especially for readers interested in how indie developers validate products, handle users, build small AI products, and publish indie games. The technical tutorials are also relatively down-to-earth, focusing on concrete issues such as DNS encryption, DoH, and self-hosted services in the context of China’s network environment. The drawbacks are that the topics are fairly scattered, covering technology, products, life, and annual summaries. The site is not as systematic as a knowledge base or course, so readers need to filter content themselves. Another issue is that some networking and DNS solutions are highly time-sensitive and may need to be revalidated after a few years due to changes in system versions, provider policies, or network conditions.
It is suitable for Chinese-speaking developers, indie developers, personal site owners, NAS/home-network tinkerers, and anyone interested in understanding personal product validation and indie game development workflows in the AI era. It is not suitable for users looking for official documentation, enterprise-grade SLAs, structured courses, or an all-in-one tool service.
The content is in Chinese and clearly aimed at domestic readers, and the articles repeatedly discuss DNS solutions that are “usable in China.” Based on the crawl, the site appears to be directly accessible; however, external resources referenced in the content—such as Google DNS, Cloudflare Workers, GitHub, and ChatGPT—may face varying degrees of access restrictions in mainland China.
