For those tasks I use most of the time block selection.
Put your cursor on the first #
character, press Ctrl``V
(or Ctrl``Q
for gVim), and go down until the last commented line and press x
, that will delete all the #
characters vertically.
For commenting a block of text is almost the same: First, go to the first line you want to comment, press Ctrl``V
, and select until the last line. Second, press Shift``I``#``Esc
(then give it a second), and it will insert a #
character on all selected lines. For the stripped-down version of vim shipped with debian/ubuntu by default, type : s/^/#
in the second step instead.

When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com
, example2.com
, and example1.com/images
on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
