8种机械键盘轴体对比

本人程序员，要买一个写代码的键盘，请问红轴和茶轴怎么选？

ABRT (Automated Bug Reporting Tool) Daemon:ABRT is an application, included in Fedora Linux Distribution, that is used to report bugs in the software packages whenever crash occurs. Due to this, ABRT also helps in creation of core dump files. Multiple packages may be needed to run various features of ABRT daemon, and their listing is as follows.

在linux调试程序，程序异常宕掉，没有core文件，很难定位问题。但是有了core文件就容易定位多了， 一般是可以通过在环境变量中设置ulimit -c unlimited。

但是现场实施人员有时会忘记设置这条命令， 因此可以通过设置linux的abrt服务来实现。

系统：CentOS7
