Operating System Notes\[EB/OL]. Baidu Tieba. \[2026-04-04]. . It primarily referenced the firewall chapter and the users and permissions chapter. The original notes mainly cited *FreeBSD Unleashed* (Tiemann B, Urban M. FreeBSD Unleashed\[M]. Wisdom East Studio, trans. Beijing: China Machine Press, 2002.), and also referenced blog posts by [πŸŽ€πŸŒΈ Xingbumeng πŸŒΈπŸŽ€](https://tieba.baidu.com/home/main?un=%E6%98%9F%E5%85%89Re) ([Internet Archive snapshot](https://web.archive.org/web/20201128071425/https://www.moebsd.cn/)). In the third edition of this book, we have drawn upon content from the FreeBSD Documentation Project to supplement the theoretical, command option, and historical sections. For license information, see the **COPYRIGHT** file. ## Apology Due to historical reasons and insufficient understanding of open-source licensing norms, we failed to properly attribute sources and authors as required by the original authors. We sincerely apologize for this. If readers have any questions, please contact `yklaxds@gmail.com`. As part of the project's goals, we will rewrite all relevant chapters as soon as possible and standardize the attribution of sources and authors. ## Community Management and Technical Maintenance [Chao Pinghe Busters](https://github.com/banbo96) (QQ nickname/WeChat name) has played an important role in the management of this community and its documentation, as well as the operation of the QQ group, WeChat official account, and WeChat group, and has created and maintained multiple associated accounts for this community. The early initiator of this project was [clean-master](https://github.com/clean-master). He funded the creation of the domain `freebsdcn.org` (no longer in use) and created the currently maintained homepage at . He encouraged ykla to create the project to maintain the related FreeBSD tutorials. [Roberta Wheeler](https://github.com/rowheel) previously funded the deployment and maintenance of this project's server (now switched to GitBook and GitHub Pages free services), and also wrote some articles. [safreya](https://github.com/safreya) developed two open-source tools for exporting this project's PDF documentation (still in use), and wrote a large number of articles. Simple, former bar manager of the Ubuntu Bar, once suggested modifying the project's chapter filenames and license agreement, which improved the maintainability of this project. The domain `bsdcn.org` for this project is sponsored by the Chinese FreeBSD Community (CFC) and ykla. Currently, the primary manager of this project is [Voosk](https://github.com/MilkGolium), who has also participated in writing some articles. Currently, the primary technical maintainer of this project is [ykla](https://github.com/ykla). ## Alphabetical List of Contributors * [5gura](https://github.com/5gura) * [algotao](https://github.com/algotao) * [Alex6357](https://github.com/Alex6357) * April SimoneπŸ₯ * [VZstless](https://github.com/atlarator) * [bduath](https://github.com/bduath) * [blu10ph](https://github.com/blu10ph) * bsdwiki * [dacheng119](https://github.com/dacheng119) * [Dedicatus5457](https://github.com/Dedicatus5457) * DogeW * [dongdigua](https://github.com/dongdigua) * [fanyang1997](https://github.com/fanyang1997) * [fjh1997](https://github.com/fjh1997) * freyr * [gua-leopard](https://github.com/gua-leopard) * heguru5 * isNijikawa * Jack * Jiacong Fang ([zldrobit](https://github.com/zldrobit)) * kuntop * LFour86 * [LuoTianyi-arm64](https://github.com/LuoTianyi-arm64) * [Li Dapeng](https://dapeng.li/) * [liguangsheng](https://github.com/liguangsheng) * livrth * [Ling Wan](https://clansty.com) * [Liulitchi](https://github.com/liulitchi) * Liu Xinyu * matatabi-wang * Mozi * [mxdyeah / mxdabc](https://mxdyeah.top/) * [nerdroychan](https://github.com/nerdroychan) * [number201724](https://github.com/number201724) * [orzyyyy](https://github.com/orzyyyy) * [peiyafei](https://github.com/peiyafei) * [pengxingwei](https://github.com/pengxingwei) * [puffinjiang](https://github.com/puffinjiang) * Qinghe [qinghecyn](https://github.com/qinghecyn) * Qingre Jiedu Koufuye * [Rintim](https://github.com/Rintim) * [ruur](https://github.com/ruur) * [Sayunosyjou](https://github.com/Sayunosyjou) * Shizhu * [Suyun114](https://github.com/Suyun114) * [tergel93](https://github.com/tergel93) * [tomblackwhite](https://github.com/tomblackwhite) * Yanyangtian * [Wang Yan Hao](https://github.com/Wang-Yan-Hao) * [wyathou](https://github.com/wyathou) * X-Ray * Xinjili Wujixin * Yangwang Tiankong * [Zomby7e](https://github.com/Zomby7e) * Ditioka * Doushuai * Jipin Daohao * [Maou-sama](https://github.com/maou-sama-desu) * πŸŽ€πŸŒΈ Xingbumeng πŸŒΈπŸŽ€ (Tieba account) * Yutian * [Wenyin Open Source Community](https://www.wenyinos.com/) ## Technical Infrastructure and Platform Support This project utilizes several open-source projects during deployment, and we thank their authors.
