Use jq command-line JSON processor to filter out a nested hash. See also: https://github.com/stedolan/jq/wiki/jq%20Cookbook
# http://stedolan.github.io/jq/
json='{"foo": {"genre":"deep house"}, "bar": {"genre": "progressive house"}, "baz": {"genre": "dubstep"}}'
echo "$json" | jq '[to_entries | .[] | select(.value.genre | contains("house"))] | from_entries'
# {
# "bar": {
# "genre": "progressive house"
# },
# "foo": {
# "genre": "deep house"

Three20 TTImageView always checks the in-memory cache *without* using any expiration age - this version solves this problem

Print out the width x height of a given image via ImageMagick identify
# ImageMagick `identify` format features is handy
# e.g. to obtain the width x height of a given image (360x480)
#
# See http://www.imagemagick.org/script/escape.php
# for a complete list of supported format characters
identify -format "%wx%h" myimage.jpg

GCC - list all the macros defined during the execution of the preprocessor
# -E is for preprocessor only
# -dM tells GCC to generate a list of #define directives
# e.g.
# #define __APPLE__ 1
# #define __SSE2__ 1
# #define __GNUC__ 4
# ...
gcc -E -dM - < /dev/null
