Issue 60 of HelloGitHub, a monthly open source project

Interest is the best teacher, HelloGitHub is to help you find interest!

Introduction to the

Share interesting, entry-level open source projects on GitHub.

This is a monthly magazine for people who are new to programming, passionate about programming, and interested in the open source community. The contents of the monthly include: various programming language projects, tools to make life better, books, study notes, tutorials, etc. Most of these open source projects are very easy to use, and very Cool. The main hope is for you to get your hands dirty and join the open source community.

• Those who can program can contribute code
• Those who cannot program can report bugs in using these tools
• Help promote projects that you think are great
• Star project ⭐ ️

As you browse and participate in these projects, you will learn more about programming, improve your programming skills, and find the fun of programming.

🎉 And the project HelloGitHub was born at 🎉

Act: This project allows you to debug GitHub Actions scripts locally. GitHub Actions GitHub Actions is a repository automation workflow feature that allows users to easily implement CI/CD with GitHub’s free computer resources and do a lot of fun things with it.

PHP project

PHPMailer is probably the most popular open source PHP email library. It can be found in many well-known PHP open source projects, such as WordPress and Yii, to support all your email development needs. Take a look at the sample code to see how easy it is to use:

      
//Import PHPMailer classes into the global namespace
//These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

//Load Composer's autoloader
require 'vendor/autoload.php';

//Instantiation and passing `true` enables exceptions
$mail = new PHPMailer(true);

try {
    //Server settings
    $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      //Enable verbose debug output
    $mail->isSMTP();                                            //Send using SMTP
    $mail->Host       = 'smtp.example.com';                     //Set the SMTP server to send through
    $mail->SMTPAuth   = true;                                   //Enable SMTP authentication
    $mail->Username   = '[email protected]';                     //SMTP username
    $mail->Password   = 'secret';                               //SMTP password
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;         //Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` encouraged
    $mail->Port       = 587;                                    //TCP port to connect to, use 465 for `PHPMailer::ENCRYPTION_SMTPS` above

    //Recipients
    $mail->setFrom('[email protected]'.'Mailer');
    $mail->addAddress('[email protected]'.'Joe User');     //Add a recipient
    $mail->addAddress('[email protected]');               //Name is optional
    $mail->addReplyTo('[email protected]'.'Information');
    $mail->addCC('[email protected]');
    $mail->addBCC('[email protected]');

    //Attachments
    $mail->addAttachment('/var/tmp/file.tar.gz');         //Add attachments
    $mail->addAttachment('/tmp/image.jpg'.'new.jpg');    //Optional name

    //Content
    $mail->isHTML(true);                                  //Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body in bold! ';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {

Sample code:

// Set the hexadecimal color
let white = UIColor(hex: "#ffffff")
let black = UIColor(hex: "# 000000")

/ / set the alpha
let colorWithAlpha = myColor.alpha(0.75)

// Set the gradient
let gradient = [UIColor.blackColor(), UIColor.orangeColor()].gradient()

let secondGradient = [UIColor.blackColor(), UIColor.orangeColor()].gradient { gradient in
  gradient.locations = [0.25.1.0]
  return gradient

import tinygrad.optim as optim

class TinyBobNet:
  def __init__(self) :
    self.l1 = Tensor.uniform(784.128)
    self.l2 = Tensor.uniform(128.10)

  def forward(self, x) :
    return x.dot(self.l1).relu().dot(self.l2).logsoftmax()

model = TinyBobNet()
optim = optim.SGD([model.l1, model.l2], lr=0.001)

#... and complete like pytorch, with (x,y) data

out = model.forward(x)
loss = out.mul(y).mean()
optim.zero_grad()
loss.backward()
optim.step()
