Why I Don't Write Web Apps (if I can help it)

This is what happens when I try to pick a language.

Note: If I didn't think it was possible to create a development environment without any of these issues (which I consider "major" for the most part), I would not have written this list.

   1. 虚拟IP。我一般用来linux和虚拟机之间共享用的，因为考虑到linux宿主机的ip是动态ip会变化。我所见到的实际用途是负载均衡。

      sudo ifconfig eth1:0 125.12.12.77   

   2. windows根据 ip查看主机名,公司内部主机名一般会是ALIBABA-XXXXX,XXXXX就是工号，这样就可以找到对应的人，当然如果是隔日的，需要考虑动态IP的问题。

      nbtstat -a IP

   3. awk
