Article is dead now, but the project is at github.com/wolfch/sqlite-3.7.3.p1. The readme file implies that this is not production ready, nor is it for experimentation. It seems like it's more of a proof of concept.

Using Vim's tabs like buffers

...Html5's srcdoc attribute, just like in Saurabh Chandra Patel's answer, who now should be the accepted answer! If you can detect IE/Edge efficiently, a tip is to use srcdoc-polyfill library only for them and the "pure" srcdoc attribute in all non-IE/Edge browsers (check caniuse.com to be sure).

What's better at freeing memory with PHP: unset() or $var = null
...pdate , is actually a language construct), but it would be interesting to know if one is better than the other. I have been using unset() for most of my coding, but I've recently looked through a few respectable classes found off the net that use $var = null instead.
