This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).
Matrix multiplication is a mathematical operation that defines the product of

| "log" | |
| "net/http" | |

The best way to safely and securely use local domains pointing to 127.0.0.1 is to edit your local settings (/etc/hosts) and add your own settings. Keep in mind if you want to use subdomains, you need to enter all variations.
Example:
# Adding bottom of your current file /etc/hosts
################# MY LOCAL DOMAINS
127.0.0.1 local.com admin.local.com
127.0.0.1 domain1.com
