Oracle需要知道一些SQL function, index，差不多了。
Linux会vi和grep大约够了。
JS是很简单的语言，能够读写也差不多了。

linux means OS internals
one guy in my former team said that we have to use root to allow
mlock() because "there is a kernel bug that makes it work with only
root", I laughed my ass off....
also knowledge about TCP protocol , IP protocol is very important,
since today's jobs are inevitably around network
many java developers start off from a pure language or windows
environment, they don't get any exposure to the system internals, so
they immediately run into problems when they try to tackle slightly
more complicated performance issues
JS is not required, most jobs are strictly divided into front-end and
back-end groups.

发帖数: 34805 | 7 I think I've tackled more slightly complex performance issues
than average java developers and OS, network stack ain't that
critical.

发帖数: 5393 | 10 why "start off from windows environment" won't give you exposure to system
internals? Compiling linux kernel helps u understand TCP/IP stack or
process scheduling?

en, 同怀念，原先goog还有个啥web finger的东东。
现在感觉和99年没啥区别，又是新一轮的IT狂潮
