7 HTML 4.x vs. HTML 5.x HTML5 is a superset of HTML 4.01 (which means most of HTML4 is still supported in HTML5) Step 1 doctype ( old doctype below is an example, several exist) Old: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" " New: (which never is going to change): <!doctype html> Step 2 content meta tag in <head> element Old: <meta http-equiv="content-type" content="text/html; charset=utf-8"> New: <meta charset="utf-8"> (utf-8 is the standard or use "iso ") Step 3 link tag in <head> element Old: <link type="text/css" rel="stylesheet" href="lounge.css"> New: <link rel="stylesheet" href="lounge.css"> Step 4 script tag (JavaScript is the standard) Old: <script type="text/javascript" src="my-file.js"></script> New: <script src="my-file.js"></script> <script> var yourock = true; For inline script code (within the HTML </script> file itself, for example inside the body tag)

Wireless access is always provided; BYOWS (Bring Your Own Web Server). </p> <script>hello();</script> </body> </html> <!doctype html> <html> <head> <title>mi1004</title> <meta charset="utf-8"> <link rel="stylesheet" href="lounge.css"> <script src="lounge.js"></script> </head> <body> <h1>welcome to MI1004!</h1> <p> <img src="drinks.jpg" alt="drinks"> </p> <p> Join us any evening for refreshing <a href="elixirs.html">elixirs</a>, conversation and maybe a game or two of Tap Tap Revolution.

10 PHP and Python Example form (.html file) with server side (.php and.py) script files <html><body> <form method="post" action="pythonhello.py">  <label>first Name: </label> <input type="text" name="first_name" size="40" /> <br /> <label>last Name: </label> <input type="text" name="last_name" size="40" /> <br /> <label>send: </label> <input type="submit" value="submit" /> </form> </body></html> <?php #!"\dev\python36\python.exe" # Get data from fields # Import modules for CGI handling if(isset($_post["first_name"])) import cgi, cgitb $fname = $_POST["first_name"]; # Create instance of FieldStorage form = cgi.fieldstorage() else $fname = ''; if(isset($_post["last_name"])) # Get data from fields first_name = form.getvalue('first_name') $sname = $_POST["last_name"]; last_name = form.getvalue('last_name') $sname = ''; print("content-type: text/html;charset=utf-8;\r\n") else $person = $fname.

12 Transfer Learning By changing the very last part in the CNN (Convolutional Neural Network), but continue to use the major first part, one can classify new images with very good accuracy vetenskapens-varld/vetenskapens-varldde-smarta-maskinernas-tid
