Locate Empty Directories from Command Line
As a software engineer that lives too much of his life on a computer, I like keeping my machine as clean as possible. I don't keep rogue downloaded files and removes apps when I don't need them. Part of keeping a clean, performant system is removing empty directories.
To identify empty directories, I use the following command:
find . -type d --empty
To remove empty directories, we can add a --delete flag:
find . -type d --empty --delete
Keeping a clean machine is easy when you know the tools that can help you. find makes identifying and eliminating easy, so don't be afraid to use it!

![Simple Image Lazy Load and Fade]()
One of the quickest and easiest website performance optimizations is decreasing image loading. That means a variety of things, including minifying images with tools like ImageOptim and TinyPNG, using data URIs and sprites, and lazy loading images. It's a bit jarring when you're lazy loading images and they just...
A minor change as it should have a single ‘-‘ on the empty predicate:
