Modifying the behavior of WordPress' sanitize_file_name()

	<?php
	/**
	* If you're using the WordPress function sanitize_file_name() and want
	* to use it with filenames like my-custom.min.css, you'll quickly find
	* out that .min.css isn't accepted as a valid extension.
	*
	* Here's a quick fix, using WordPress' filtering mechanisms.

Checking LSI RAID storage status in Linux

	# This will trigger on the output NOT being "Optl" (Optimal). This works for me,
	# your mileage may vary. One problem in using more "verbose output" from the
	# storcli64 binary is that it always (?) outputs some sort of legend with all
	# the various status types explained, so it always contains the text "Degraded"
	# for example. This minor script will simply search for what we want, which is
	# a RAID in optimal state, and if NOT found, perform a full status scan and send
