Takes all jpgs from the source folder and copies only the jpgs that present a significant difference, used to remove repeated frames from webcams output.
#/bin/bash
#We only allow empty destination folders.
if [ -d "$2" ]; then
echo "Directory already exists"
exit
fi
#If it doesn't exists create it.
if [ ! -d "$2" ]; then
mkdir $2
fi

Renames all jpgs in a folder sequentially, I use it to make surveillance bulk files compatible with OpenShot import functionality.
if [ ! -d "$1" ]; then
echo "Directory doesnt exists"
exit
fi
cd $1
a=1
for i in *.jpg; do
new=$(printf "%09d.jpg" "$a") #09 pad to length of 9

Do you want to compare the repositories of 27+ students to catch if one of them is cheating?
<?php
$dirs = array_slice(scandir('.'), 2);
for($i=0;$i<count($dirs);$i++){
if ( is_dir($dirs[$i]) ){
$base = $dirs[$i];
for($j=0;$j<count($dirs);$j++){
if ($i!=$j) {
if ( is_dir($dirs[$j]) ){
$against = $dirs[$j];

DOM

  • ¿Qué es el DOM? Document Object Model

  • ¿Qué es un selector? Nos permite encontrar uno o más elementos HTML

  • ¿Cuál es la diferencia entre document.getElementById y document.getElementsByClassName? Además de que regresan elementos por distinto selector, el Elements regresa especificamente un arreglo, así devuelva un sólo elemento dentro.
