WordPress with Cloudflare CDN - WordCamp Apatin 2023

Talk given at WordCamp Apatin, Serbia, on May 27, 2023.

Affordable hosting means slow sites; serious hosting means serious bills — and either way you're on your own when the attacks start. This talk walks through putting Cloudflare in front of a WordPress site as the practical answer to all three: what a CDN actually does, how Cloudflare fits in, what changes at the domain and DNS level, which of its security, performance and reliability services are worth turning on, and how far the official WordPress plugin gets you. Plus a few advanced options, and a couple of myths worth busting.

For developers and site owners on modest hosting who want a faster, safer site without moving anywhere.

4. ]{ DARK MATTER The standard model of cosmology indicates that the total mass–energy of the universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy. Thus, dark matter constitutes 84.5% of total mass, while dark energy plus dark matter constitute 95.1% of total mass– energy content. The great majority of ordinary matter in the universe is also unseen, since visible stars and gas inside galaxies and clusters account for less than 10% of the ordinary matter contribution to the mass-energy density of the universe. The most widely accepted hypothesis on the form for dark matter is that it is composed of weakly interacting massive particles (WIMPs) that interact only through gravity and the weak force.
