how a 程序猿 doubled his salary？

• One thing i can say, no matter what position i was in or what was my salary, i never stopped studying some extra times. Maybe i dont study or research 5-6 hours daily like before, but at least i spend some time regular basis. Because i know, in order to survive in this huge tech world, you should always be updated and prepared
  无论是什么职位或者拿多少薪水，我从来没有停止在业余时间学习。也许我没有像刚入行那样每天花5-6小时学习，但我至少会定期花一些时间。因为我知道，要在这个变化巨大的科技世界里生存，你必须时刻进行着准备和更新。

• Work insanely hard. 40 hour work weeks are good and healthy, but I think it's harder to become super successful without working a lot. As an employee when I was getting paid that 130k I worked 65/hr a week even though I was only getting paid for about 45 of those hours, just because I wanted them to know I was insanely aggressive
  每天疯一样的工作。每周工作40个小时好像挺好并且健康，但是如果你想要成功你必须付出更多。

• Invest in skill sets that will pay. No use learning something just because you like it. Learn something for which companies are willing to pay top dollar.
  学习一些公司愿意付钱的技术，而不是只学习你喜欢的技术。

• Look at your colleagues who are 10+ years older than you and ask yourself if you wanna be doing the same stuff they are doing today. If the answer is no, find out what you need to do differently so as not to land in the same position as theirs ten years from now.
  看一看你身边比你入行早的loser程序员，想想你需要做什么才能避免自己几年后成为他们那样。（大概指那些只是混口饭吃安于当前状况的程序员吧）

• Make Computer Science fundamentals very strong , mainly DataStructure & Algorithm.
  对计算机科学基础知识有着很深的了解，特别是数据结构和算法。

• No point of being a master of single technology like Java or Python. Learn several technologies.It will broaden your skill-sets & thinking.
  不要只沉迷于一种技术比如java或者python。语言决定世界观，这样可以扩展你的思维方式和技能树。

• Heard any new technology, like BigData or Machine Learning. Make sure to understand that and implement a POC. Don't just read, make sure, you are very much aware of fundamentals
  当你听到一个新技术，要尝试去真正的理解它。

• If you don't like your job or Manager don't react, keep smiling and keep working and look for new job. Never destroy your relationship with people
  如果你不喜欢你现在的工作或者你的经理，还是对他们保持微笑继续工作，并且低调找下一份工作。没有必要把你和上司或者公司的关系搞砸。

• Read .. Read ... Read ... CODE IT
  生命不息，coding不止

• Blog about what you do. Write white papers on particularly innovative solutions you develop. Write about development best practices, your thoughts on languages and platforms, bug fixes, you name it. If you don't have a blog, you're missing out on the ability to walk into an interview with someone who knows more than just your resume, but also your development style and personality.
  写一个博客，记录你的技术成长：项目里你提出的创新的解决方案，最佳实践，你关于语言和平台的思考，bug的追踪修复，命名等。如果你没有博客，面试时你就失去了展示自己能力的一个方式，只能通过简历。

• Find a problem that a lot of people struggle with that you can solve with your skill set. Write an open source solution, publish it, and maintain it. When you make updates, include the change log in your blog.
  找到一个困扰很多人的难题并且你可以通过你的技术解决它。为此写一个开源项目，发布它，然后不断维持这个项目。当你更新的时候，把改进的地方写进你的博客。

最后

有很多票数投给了，想赚大钱快转行！
就是建议转管理成为公司管理层或者自己开公司。毕竟相比之下，成为万里挑一的顶尖程序员有的时候不是靠努力就能做到的（虽然更多的人连努力都不够还没到要拼天赋的时候）。尤其是当你的动机只是想赚钱，中间这么长时间的持续付出如果你自己感觉不到乐趣的话还是太枯燥了。
