Muoversi da jQuery a javascript

Usare Javascript invece che jQuery nei tuoi progetti può essere una mossa molto intelligente, non solo imparerai più a fondo le dinamiche del linguaggio e diventarai naturalmente più esperto, ma incrementerai notevolmente le performance del tuo sito.

_{Se lavori in grossi progetti e applicazioni che richiedono tante linee di codice lavorare in puro Javascript è un po frustrante, in questo caso un mix di JQuery e Javascript è necessario.}

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)

	#!/bin/bash

	echo -e "\nbenchmark.sh -n<number of requests> -c<number of concurrency> <URL1> <URL2> ..."

	echo -e "\nEx: benchmark.sh -n100 -c10 http://www.google.com/ http://www.bing.com/ \n"

	## Gnuplot settings
	echo "set terminal png
	set output 'benchmark_${1}_${2}.png'
	set title 'Benchmark: ${1} ${2}'
