第一，去linkedin上按照语言关键字搜索，看看你要的地区，哪种语言提供的工作机会
多，级别高。例如，你可以搜索湾区50miles以内，java的职位有多少，c/c++和php的
有多少。不仅要看多少，还要看职位的级别和待遇。software engineer < sr < staff
< principal。QA < QE = UI/Front < ServerSide Engineer

第二，看你的兴趣和将来的职业发展。想做通信和系统底层的，学c/c++。想做
enterprise software，尤其是应用/商用软件的，学java。想快速搭建网站的，想做UI
的，学php/ruby/javascript。每个领域都有其独特的技术需求。

第三，语言是不是相通的？

是相通的，但你必须要起码精通一门。目前来看，一般来说，最好在这几个语言中精通
一个：java/c.c++/python/php。虽然每年都有一些新的语言冒出来，例如scala之类的
，但是想要代替主流语言，还是需要好几年的。虽说语言的语法是类似的，但是如果做
到熟练，那不写一年的代码恐怕很难做到“熟练”吧。

除此之外，每个语言都有自己的library和framework。就说java吧，随手一拎就是一大
堆：

tomcat,log4j,junit,testng,ant,maven,apache common,apache http,jdbc,xml
parser,json parser,annotation,injection, 还有hadoop那一大大大大堆东西

没有个2-4年，而且找到了一个巨能锻炼学习的职位，很难说是熟练java吧？语法只能
是一个语言最最基本的东西

结论：技术积累要和职业发展结合起来，知识面要广，但在有些领域要做精。好在美国
做码工可以做到四五十岁，能慢慢折腾。

https://killer.sh Pre Setup Once you've gained access to your terminal it might be wise to spend ~1 minute to setup your environment. You could set these: alias k = kubectl # will already be pre-configured export do = "--dry-run=client -o yaml" # k get pod x $do export now = "--force --grace-period 0" # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section . Question 1 | Contexts Task weight: 1% You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
