Commodore 64 (Vic 20, Pet, etc) emulator from Raspberry Pi Raspbian

I can confirm this install method (source) worked with a Raspberry Pi 4 using Raspbian Buster.
Compiles Vice and installs into /usr/local/bin. Initial launch reports a sound issue. If you go into settings (F12), there’s a sound configuration you can change to “Alsa”.

Ubuntu fstab; mount external drive at boot

Procedure for rescuing an Ubuntu Server when the boot file gets messed up due to a misnamed external hard drive.
Backup the current fstab file:

sudo cp /etc/fstab /etc/fstab.old

List the drives:

sudo blkid

Example output:

/dev/sda1: UUID="8F1B-7691" TYPE="vfat" PARTUUID="eea0152e-f8aa-4d1f-8d44-172261edd5a2"
/dev/sda2: UUID="5be250be-a857-11e8-9dd6-a82066361186" TYPE="ext4" PARTUUID="9ba42200-226c-4e67-a667-649658dfbd0b"
/dev/loop0: TYPE="squashfs"
/dev/loop1: TYPE="squashfs"
/dev/loop2: TYPE="squashfs"
/dev/loop3: TYPE="squashfs"
/dev/sdb1: LABEL="media" UUID="746622C40BE949C9" TYPE="ntfs" PTTYPE="dos" PARTUUID="e2bd323d-a7bb-4be8-83bb-4d547fb45e37"

Edit the fstab file:

sudo pico /etc/fstab

Example:

GNU nano 2.9.3 /etc/fstab
UUID=5be250be-a857-11e8-9dd6-a82066361186 / ext4 defaults 0 0
UUID=8F1B-7691 /boot/efi vfat defaults 0 0
/swap.img none swap sw 0 0
#Device #Mountpoint #fs-type #options #dump #fsck
/dev/sdb1 /media/usb ntfs defaults 0 0

Save, reboot.

Force Ubuntu Server to redirect http to https

If you want to redirect your web address from http to https, you will have to configure your server’s virtual host file.
Edit the virtualhost file to update the port 80 portion; replace “test.com” with your domain name:

sudo nano /etc/apache2/sites-available/test.com.conf

Edit the :80 portion (in bold), replacing <ip_or_host> with your domain name:

<VirtualHost *:80>
        ServerName <ip_or_host>
        Redirect "/" "https://<ip_or_host>"
</VirtualHost>
<VirtualHost *:443>
        ServerName <ip_or_host>
        DocumentRoot /var/www/whateverfolder
        SSLEngine on
        SSLCertificateFile      /etc/ssl/certs/apache-selfsigned.crt
        SSLCertificateKeyFile /etc/ssl/private/apache-selfsigned.key
        <Directory /var/www/whateverfolder/public>
           DirectoryIndex index.php
           AllowOverride All
           Require all granted
        </Directory>
</VirtualHost>

Save the .conf file
Modify the default Apache config file:

sudo nano /etc/apache2/sites-available/000-default.conf

Then add the bold portion (starting with “RewriteEngine on”) to the bottom of the file. Replace example.com with your domain name.

<VirtualHost *:80>
     ServerAdmin admin@example.com
     DocumentRoot /var/www/html/example.com/
     ServerName example.com
     ServerAlias www.example.com
     <Directory /var/www/html/example.com/>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
     </Directory>
     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined
RewriteEngine on
RewriteCond %{SERVER_NAME} =example.com [OR]
RewriteCond %{SERVER_NAME} =www.example.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

Enable the .conf files:

sudo a2ensite test.com.conf
sudo a2ensite 000-default.conf

Reboot your apache server:

sudo service apache2 restart

Test your server config in your web browser by typing in: http://www.example.com
