When I started this site decades ago, I followed the usual path at that time to launch sites, shared hosting. There were many vendors to choose from but nothing like the quantity and diversity of what’s available today. I registered the domain, settled on a small vendor for $5/month, got my cPanel and terminal login — Continue reading Β»

Does It Make Sense To Self-Host Mail Server?

    πŸ“‚ Email,Internet     # ,     πŸ—¨ No Comments

    πŸ“‚ Internet     #     πŸ—¨ No Comments

Nowadays many people know of IP addresses. Those 4 numbers (technically known as octets) separated by dots (e.g. 173.162.146.61) which connect all of our devices to the Internet and allow them to find each other.

HTTP to HTTPS Migration

    πŸ“‚ Google,Internet,Web     #     πŸ—¨ No Comments

A universally secure internet may have its defenders and detractors but like it or not, Google is going to force site encryption (https) across the board.
