here is the way we compute digests and compare them with the digests compted by Epoch
<?php
public function getDigest($flexpost, $source_encoding=null) {
if ( array_key_exists('epoch_digest', $flexpost) )
unset($flexpost['epoch_digest']);
ksort($flexpost);
$sorted_string = urldecode(strtr(http_build_query($flexpost), ['&' => '', '=' => '']));
if ( $source_encoding )
$sorted_string = mb_convert_encoding($sorted_string, self::UTF8_ENCODING, $source_encoding);
return hash_hmac('md5', $sorted_string, $this->hmac_key);

How to code my get number float at Epitech (require my_get_number or atoi and my_power_rec or my_power_it or pow)
integer = my_getnbr(str)
str = str after the '.' character
decimal = my_getnbr(str)
decimal = decimal / 10^(strlen(str)) * (1 if number is strictly positive, -1 else)
number = integer + decimal
example:
[line] [values]
[1] str = '-13.04' integer = -13
[2] str = '04' integer = -13

Workshop Blender

An introduction to blender

According to wikipedia, Blender is a professional, free and open-source 3D computer graphics software toolset used for creating animated films, visual effects, art, 3D printed models, interactive 3D applications and video games. Today we will try to modelize some basic objects and familiarize with the software.

A table for three please !

Your objective is to try to modelize a table with some chairs around. You can check the modeling section of the Blender documentation, you can ask questions as well. If you finish ealier than the other, you can even try to apply some texture to your model, maybe even some materials !

Shortcuts cheetsheet

Shortcuts in blender are pretty powerfuls, you can easily combine several of them to improve your workflow.
