Course logistics

• How can we get a file such as my bank.html from the MultiLab to my desktop so I can turn it into Canvas?
  You might use FileZilla (an application that runs on Windows) or scp (like ssh but copying a file) on a Mac or Unix. There are other similar programs, including WinSCP and Cyberduck.

Assignment 1: Simple HTML page

• My console does not have the HTML Validator on it. Is there a way that I can put the HTML validator on my console?
  It's an extension, called HTML validator (for Firefox); there are similar ones for other browsers.

Assignment 2

• In the Zoom last Thursday you were able to connect to mysql without needing to enter a password. Can you please explain how I can do that? Its definitely getting tedious to type out my password everytime.
  On a MultiLab machine, run

  mysql_config_editor set --user=abcd123 --host=mysql.cs.uky.edu --password
  

  Of course, replace abcd123 with your LinkBlue name.

  The program will prompt you for your mySql password, which is typically u followed by the last 7 digits of your LinkBlue ID number.

  After you have finished this configuration, mysql should no longer ask you for this information, nor should you need to provide it every time you invoke mysql.

• How can I convert runtime errors in the CGI program to messages embedded in the resulting HTML file?
  PHP: put these lines near the top of your PHP code:

     ini_set('display_errors', 1);
     ini_set('display_startup_errors', 1);
     error_reporting(E_ALL);
  

  Perl: again, near the top:

     use CGI::Carp qw(fatalsToBrowser warningsToBrowser);
  

  Python:

     import cgitb
     cgitb.enable()
