Serve a Directory with PHP
Many developers have a giggle at PHP, even looking down at the language, but let's be honest: most of our blogs are powered by it (WordPress) and it's a great language to dabble around with. I cut my teeth on PHP, though I prefer to avoid PHP these days.
But when I need to experiment with a simple PHP coding task for the sake of a blog feature, I look for the simplest possible serving solution to accomplish that feat. Luckily PHP provides me a quick solution for testing:
php -S localhost:8888
The command above allows for serving of a directory via PHP, thus allowing for a simple PHP "site" to be served enough to confirm that my code testing works properly.
Serving a directory with PHP, python, or Node.js ... the same problem solved for different languages!
One event that's always been lacking within the document is a signal for when the user is looking at a given tab, or another tab. When does the user switch off our site to look at something else? When do they come back?
When I first wrote MooTools ElementFilter, I didn't think much of it. Fast forward eight months later and I've realized I've used the plugin a billion times. Hell, even one of the "big 3" search engines is using it for their maps application.
