TRIM Enabler for OS X Yosemite 10.10.3
#
# UPDATE for 10.10.4+: please consider this patch obsolete, as apple provides a tool called "trimforce" to enable trim support for 3rd party SSDs
# just run "sudo trimforce enable" to activate the trim support from now on!
#
# Original version by Grant Parnell is offline (http://digitaldj.net/2011/07/21/trim-enabler-for-lion/)
# Update July 2014: no longer offline, see https://digitaldj.net/blog/2011/11/17/trim-enabler-for-os-x-lion-mountain-lion-mavericks/
#
# Looks for "Apple" string in HD kext, changes it to a wildcard match for anything

# Alternative to http://www.groths.org/trim-enabler-3-0-released/

Dyskretna transformata Fouriera
1. sinus
wyznaczyc widmo dla sygnalu ktory
a) w n probkach bedzie mial calkowita liczbe okresow
b) w n probkach bedzie mial niecalkowita liczbe okresow
fft/g + semilogy -> widmo
2. dyskretna transformata Fouriera (probkowanie widma ciaglego)
a) f_sin \in m*fpr/N, m \in {0,1,..,N-1}
