Debugging & Optimizing Wordpress Speed with XHProf

This guide will show you how to generate and view XHProf reports of your WordPress Site.

This is useful so you can drill-down and see exactly how many microseconds each of your scripts and functions (themes & plugins) are running when generating a page -- slowing down your website visitors' page load speed.

Projected Future Spread of COVID-10 on Earth (e2a Apr 07)

I woke up on April 2nd to discover that over 1 million people on earth had tested positive for coronavirus. "I couldn't find a website that was extrapolating the COVID-19 dataset, so I decided to build one"

It took over 4 months for COVID-19 to hit 1 million world-wide, and the graph was showing a horrifying exponential growth of cases. When I saw this, a question popped-into my head: when will it hit 2 million? (spoiler: it took only 13 days to go from 1 million to 2 million)

When will it infect 4 million? 8 million? 100 million? 1 billion? 50% of the population on Earth?

I searched-and-searched, but I couldn't find a website that was extrapolating the COVID-19 dataset daily to predict the future spread of the virus, so I decided to build one myself.
