Bash Script to find Geolocation from IP Addresses in apache's access log. You need to have "geoiplookup" package from GeoLite package. The excerpts are taken from http://danielmiessler.com/blog/a-simple-script-for-harvesting-dns-country-state-and-city-information-from-a-list-of-ip-addresses
#!/usr/bin/env bash
cat /var/log/apache2/access_log | awk '{print $1}' > ips.txt
uniq ips.txt > uniqips.txt
IPS=`cat uniqips.txt`
for i in $IPS
do
echo "$i,`geoiplookup $i | cut -d "," -f2 | sed -e 's/^[\t]//'`" >> ipinfo.csv

How to calculate the current CPU load with Node.js; without using any external modules or OS specific calls.
var os = require("os");
//Create function to get CPU information
function cpuAverage() {
//Initialise sum of idle and time of cores and fetch CPU info
var totalIdle = 0, totalTick = 0;
var cpus = os.cpus();
//Loop through CPU cores

`classes.dex` method count helpers. Requires smali/baksmali from https://code.google.com/p/smali/ and dexdump from the build-tools in the Android SDK be on your PATH.
function dex-method-count() {
cat $1 | head -c 92 | tail -c 4 | hexdump -e '1/4 "%d\n"'
}
function dex-method-count-by-package() {
dir=$(mktemp -d -t dex)
baksmali $1 -o $dir
for pkg in `find $dir/* -type d`; do
smali $pkg -o $pkg/classes.dex
count=$(dex-method-count $pkg/classes.dex)
name=$(echo ${pkg:(${#dir} + 1)} | tr '/' '.')
