可能如果专长于一个领域，会比较容易拿到好的工资，比如
1. embedded software design，(DSP, micro processor，embedded OS, how to get started? I don't know…. )
2. kernel programming (file system, what youtube is doing?)想进入这个行业啊，估计难度对我来说挺高。
3. computer vision/image processing 不想进去了
4. database applications for bank…high salary…but yrs of experiences seems to be far beyond the required ones
5. ….
