Cgroups is a flexible Linux kernel feature to limit, police and account resources usage. A cgroup is a set of tasks for a subsystems, that is typically a resource controller.
A file system of type cgroup is mounted and all operations are run over it.
The installation can be done using any of libcgroup, cgmanager or systemd.
With GitHub Actions, a workflow can publish artifacts, typically logs or binaries. As of early 2020, the life time of an artifact is hard-coded to 90 days (this may change in the future). After 90 days, an artifact is automatically deleted. But, in the meantime, artifacts for a repository may accumulate and generate mega-bytes or even giga-bytes of data files.
It is unclear if there is a size limit for the total accumulated size of artifacts for a public repository. But GitHub cannot reasonably let multi-giga-bytes of artifacts data accumulate without doing anything. So, if your workflows regularly produce large artifacts (such as "nightly build" procedures for instance), it is wise to cleanup and delete older artifacts without waiting for the 90 days limit.
Using the Web page for the "Actions" of a repository, it is possible to browse old workflow runs and manually delete artifacts. But the procedure is slow and tedious. It is fine to delete one selected artifact. It is not for a regular cleanup. We need

** 由于此文年事已久，可能某些 URL Schemes 已失效，可在评论区留言指出！(最后更新于 2024.10.28)
由于苹果的各应用都是在沙盒中，不能够互相之间访问或共享数据。但是苹果还是给出了一个可以在 APP 之间跳转的方法：URL Scheme。简单的说，URL Scheme 就是一个可以让 APP 相互之间可以跳转的协议。每个 APP 的 URL Scheme 都是不一样的，如果存在一样的 URL Scheme，那么系统就会响应先安装那个 APP 的 URL Scheme，因为后安装的 APP 的 URL Scheme 被覆盖掉了，是不能被调用的。
