很多人看到深度学习，总会想到ai这两个字母，总会进而引申到黑客帝国之类的科幻电
影。
现实中的ai当然没有那么牛逼（我不排除有这么牛逼的可能，只是现在还不太可能）

但是深度学习能干很多你眼中不牛逼，而很实际的应用。

举个简单例子，老夫做过一个识别婴儿哭声的patten应用，用在普通人的设备上，比如
alex，只要半夜收到婴儿哭声就叫你起床换diaper/喂奶，收到你家的猫叫春声，屁都
不放一个。怎么辨别是不是婴儿哭声，弱智的做法是收集上地球上所有婴儿的哭声弄成
一个大的声线数据库，随便来个声音就去这个数据库里面检索，半弱智的做法就是老夫
这样，在这个数据库里面寻找patten，把patten生成后，以后随便来个声音只需要剥成
patten，往我生成的patten上靠就行了，准确率还蛮高的，但是空间复杂度会降低很多
个量级。为什么说是半弱智，因为老夫的功力也就这样了，相信还有更好的做法。

这只是深度学习的弱逼应用，还有很多牛逼级别应用一堆牛人正在加班加点的干，只要
做出来了，妥妥地发大财。alphago勉强算一个，因为不挣钱。自动驾驶算，也能挣钱
，但是不成熟。

女大只是搭上了深度学习的东风，属于基建类厂家，不是决定性的，类似于别人吃肉他
喝汤这种。

等日后某一天突然出来一个超级应用，市场大爆发，女大只要还是现在的市场地位肯定
就会旁上了，市值绝逼会超过现在的古董IT公司(爱逼庵，巨硬，牙膏），老夫把话撂
这里了，真不怕被挖坟。

CKA Simulator Kubernetes 1.22

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 ...
