划了4年水，感觉自己的职业生涯快到头了

背景 首先我是个菜鸡，工资也低的一笔。 刚毕业时候在一家国企上班干 app 开发，干了快两年的时候，跳槽到了一家小厂干安全。投了不少简历都没有回音，只有这家小厂要我就来了。当时说好了会接触一些底层的东西，然而平时也就写 python 脚本，逆向，android 上写了一些风控的东西，感觉有点 low，工资也不高，当初没敢多要，hr 给的比我要的还高。刚刚 leader 谈了谈明年的规划，现在想跳槽。 现在也是很尴尬，原来 app 开发的东西也忘了不少，然后其实我想干 framework 开发，自己对 ams,pms 还算挺了解的，平时也根据他们原创了一点微小的解决方案。最近开始 fork 一个 aosp，买个 pixel 改改刷刷练习一下。 理想毕竟是理想，Android 低端不好混，没什么经验跳到 framework 上去感觉也是挺难的，跳回 app 开发又不甘心，现在的状态貌似是干了快4年没有特别精通的东西。最近闹的裁员，我司也是其中之一。加薪怕是没戏了，然而生活还要继续，跳槽避无可避。 现状分析 移动开发已经处于饱和的阶段，Android开发也不如当年盛况，已经不再像前几年前那么火爆。正如一种编程语言如果经历过盛极一时，那么必然有这样的一条曲线，像我们学的正弦曲线先急速上升，然后到达顶点，然后再下降，最后再趋近一个平稳的值。 目前市场上初中级水平的开发人员已经供大于求

问题 I'm trying to avoid terminal states of RxJava chains in my app written in Kotlin, so I found out that it is right thing to transform Observable<T> to Observable<Result<T>> where Result is sealed class. sealed class Result<T> data class Success<T>(val data: T) : Result<T>() data class Failure<T>(val throwable: Throwable) : Result<T>() And let's say I have this network request observable. fun getOrganization(): Observable<Result<Boolean>> { return api.getOrganization("google") .map { Success
