What Documentation as Tooling Means “Documentation as tooling, tooling as a product” is a slogan I have repeated many times in my previous blog posts. A good document is no match for a tool that is pleasant to use.

What Falco Is Falco is a cloud-native runtime security project contributed to the CNCF by Sysdig. Falco implements an extensible event rule filtering engine. Through a series of operations — capturing events, matching security rules, and producing alert notifications — it can surface security problems in a system. The events come from system calls, and it also supports an ebpf probe; the rules are open source [1] and you can define your own extensions [2].微信公众号FalcoKubernetesSecurityToolsOperationshttps://www.chenshaowen.com/en/blog/how-to-add-self-hosted-runners-to-github-action.htmlFri, 04 Dec 2020 00:00:00 +0000Fri, 04 Dec 2020 00:00:00 +0000https://www.chenshaowen.com/en/blog/how-to-add-self-hosted-runners-to-github-action.html1.
