| # works with a file called VERSION in the current directory, | |
| # the contents of which should be a semantic version number | |
| # such as "1.2.3" | |
| # this script will display the current version, automatically | |

rsync (Everyone seems to like -z, but it is much slower for me)
| # delete local tag '12345' | |
| git tag -d 12345 | |
| # delete remote tag '12345' (eg, GitHub version too) | |
| git push origin :refs/tags/12345 | |
| # alternative approach | |
| git push --delete origin tagName | |
| git tag -d tagName |
| Step 1: Upgrade Packages | |
| # yum update | |
| # yum groupinstall "Development Tools" | |
| Step 2: Installing Recommended Packages | |
| # yum install gcc-c++ patch readline readline-devel zlib zlib-devel | |
| # yum install libyaml-devel libffi-devel openssl-devel make | |
| # yum install bzip2 autoconf automake libtool bison iconv-devel | |
| Step 3: Install RVM ( Ruby Version Manager ) |

When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)

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
