[Legacy GOPATH mode] How to `go get` private repos using SSH key auth instead of password auth.

WARNING: This gist was created in 2013 and targets the legacy GOPATH mode. If you're reading this in 2021 or later, you're likely better served by reading https://tip.golang.org/cmd/go/#hdr-Configuration_for_downloading_non_public_code and https://golang.org/ref/mod#private-modules.

$ ssh -A vm
$ git config --global url."git@github.com:".insteadOf "https://github.com/"
$ cat ~/.gitconfig
[url "git@github.com:"]
	insteadOf = https://github.com/
$ go get github.com/private/repo && echo Success!
Success!

【译】Docker 和子进程“僵尸化”问题

【译】Docker 和子进程“僵尸化”问题

作者 Hongli Lai 看着像是华人，可惜没找到文章的中文版本，于是就很土鳖地手翻了一遍。文章的措辞很口语化，因此意译为主。点击这里可以阅读原文。

在构建 Docker 容器时，我们需要注意子进程的“僵尸化”问题（PID 1 Zombie Reaping Problem）。这会导致不可预知的和看起来匪夷所思的问题。本文解释了这个问题，也解释了如何去解决，并提供了一种预构建方案：Baseimage-docker 。
