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

, 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

What is strict aliasing? First we will describe what is aliasing and then we can learn what being strict about it means.
In C and C++ aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++ the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule. If we attempt to access a value using a type not allowed it is classified as undefined behavior(UB). Once we have undefined behavior all bets are off, the results of our program are no longer reliable.
Unfortunately with strict aliasing violations, we will often obtain the results we expect, leaving the possibility the a future version of a compiler with a new optimization will break code we th

Highly recommended things!
This is my five-star list. These are my favorite things in all the world.

After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work. | |
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0." | |
Database files have to be updated before starting the server, here are the steps that had to be followed: | |
# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default | |
brew unlink postgresql | |
brew install postgresql@9.6 | |
brew unlink postgresql@9.6 | |
brew link postgresql |
