Chapter 1: Installing the Software If you have just installed Virtualmin on a stock server or VPS, you're probably running CentOS 6  at the time of this writing (October 2014). CentOS 7 has just been released recently, and Virtualmin support for it is not as matured or stable compared to CentOS 6   CentOS 6.5 (and 6.6)  ships with the following default software:           PHP 5.3.3  (this version of PHP has reached its end of life and is no longer supported by the PHP team)         MySQL 5.1.73  (a very old version of MySQL server.

We’ve had the HTML <video> element for over a decade. Yet, everyone still defaults to embedding YouTube frames instead of hosting their own videos. The underlying problem is that the <video> element isn’t suitable for embedding short video files on webpages. Sure, the <video> element works great for large streaming platforms and tube sites. However, video is nowhere near as simple to use as other adaptive embedded media, such as responsive images. You need half an hour of learning to get started with responsive images. All you need for responsive images is to include a specially formatted list of an image in different sizes and file formats in your HTML document. The web browser uses the list to pick a format it supports at the right dimensions for the visitor’s device. Here’s a slightly simplified example: < picture > < source type = "image/avif" ...
