评论总结
评论主要观点总结:
- 对能力系统实用性的质疑
- mikewarot质疑能力系统更像是运行单一程序的工具包而非日常可用的操作系统 "Why is it that every Capability based system seems to be a toolkit for running a single program instead of an OS ready for daily use?"
- 项目维护状态的担忧
- kragen指出Capros项目已三年未更新 "Seems like Charlie hasn't been merging pull requests in three years"
- silasdavis发现官网链接失效 "Most of the links seem to be broken"
- 能力系统的教育价值
- mfedderly分享跟随Shapiro博士学习Coyotos操作系统的难忘经历 "One of the most memorable classes was a 3 hour session where we worked through the boot sequence step by step"
- 能力安全模型的优势
- btilly认为能力模型比ACL更安全 "For people who understand OO, capabilities are the simplest model in the world"
- pyrolistical用Google文档链接比喻能力系统 "It's like sharing google doc link. You configure the link to be read only or read/write"
- 安全与易用性的平衡
- contrarian1234质疑过度安全带来的复杂性 "Most of my 'wtf is going on' moments on Linux have to do with permissions"
- 但承认软件仓库的安全价值 "When was the last time you apt-get'ed some software and had your documents stolen?"
- 历史案例与经验
- iberator提到Intel iAPX 432的失败案例 "Intel did this is 1989 with iAPX 432...that's it failed hard"
- retrac详细介绍KeyKOS/GNOSIS系统设计 "The core abstraction is simpler than the Unix process model"
- 现代能力系统发展
- ahlCVA指出L4系列微内核中的Fiasco.OC "There is also a relatively modern capability-based kernel in the L4 family"
