[WordPress] Remove Google Fonts in Theme Fluida

 , ,

I usually try to avoid Google products, especially when it comes to web tracking, although I’m a big fan of what they do in other technologies.
Today I was testing another WordPress Theme called Fluida, a free theme from Cryout Creations. It’s clean and simple, the only thing that bothers me, is the usage of the Google Fonts API. Even if you don’t enter a Google Font in the settings, it’s connecting to the API.

Google Fonts has advantages as well as disadvantages. Read more about it here.

There are a few WordPress plugins to remove Google Fonts (e.g. Autoptimize), but I tried to avoid another plugin and wanted to do it manually. After a short search through the theme I found “includes/styles.php”. There you just had to comment out the following lines and it’s done.

	// Google fonts
        $gfonts = array();
	$roots = array();
	foreach ( $cryout_theme_structure['google-font-enabled-fields'] as $item ) {
		$itemg = $item . 'google';
		$itemw = $item . 'weight';
		// custom font names
		if ( ! empty( $options[$itemg] ) && ! preg_match( '/custom\sfont/i', $options[$item] ) ) {
				if ( $item == _CRYOUT_THEME_PREFIX . '_fgeneral' ) { 
					$gfonts[] = cryout_gfontclean( $options[$itemg], ":100,200,300,400,500,600,700,800,900" ); // include all weights for general font 
				} else {
					$gfonts[] = cryout_gfontclean( $options[$itemg], ":".$options[$itemw] );
				};
				$roots[] = cryout_gfontclean( $options[$itemg] );
		}
		// preset google fonts
		if ( preg_match('/^(.*)\/gfont$/i', $options[$item], $bits ) ) {
				if ( $item == _CRYOUT_THEME_PREFIX . '_fgeneral' ) { 
					$gfonts[] = cryout_gfontclean( $bits[1], ":100,200,300,400,500,600,700,800,900" ); // include all weights for general font 
				} else {
					$gfonts[] = cryout_gfontclean( $bits[1], ":".$options[$itemw] );
				};
				$roots[] = cryout_gfontclean( $bits[1] );
		}
	};

Software

[Firefox] ShadowFox + Add-Ons

 , , ,

Since the Dark Theme in Firefox 68.0.2 still has a flashing white page when opening a new tab, it’s no useable dark theme in my opinion.
That’s why I prefer ShadowFox (Github) instead of the native dark theme. Easy to install and many ways to do further customizing.

Firefox Add-ons I use:

Also, I like bookmarks in the toolbar centralized. Just append the following lines to the userChrome.css.
The file is placed in your Firefox Profile: ~/.mozilla/firefox/profile_name/chrome/userChrome.css

#PersonalToolbar {
  display: flex !important;
  justify-content: center !important;
}

LXC, Proxmox, Wireguard

[Wireguard] Preparing Proxmox Host for Wireguard in LXC

 , ,

I followed this guide for using Wireguard inside LXC on Proxmox. (Also helpfull)

echo "deb https://deb.debian.org/debian/ unstable main" > /etc/apt/sources.list.d/unstable.list
printf 'Package: *\nPin: release a=unstable\nPin-Priority: 90\n' > /etc/apt/preferences.d/limit-unstable
apt update
apt install wireguard

But as i ran “modprobe wireguard” I just got:

modprobe: FATAL: Module wireguard not found in directory /lib/modules/5.0.15-1-pve

So I ran “dkms autoinstall”… but no success.

Error! Your kernel headers for kernel 5.0.15-1-pve cannot be found.
Please install the linux-headers-5.0.15-1-pve package,
or use the --kernelsourcedir option to tell DKMS where it's located

As I run “apt install pve-headers” it installed new pve-headers but for a different kernel:

pve-headers pve-headers-5.0 pve-headers-5.0.21-1-pve

As expected, “modprobe wireguard” still returned 

modprobe: FATAL: Module wireguard not found in directory /lib/modules/5.0.15-1-pve

So i checked my current kernel with “uname –kernel-release” and since my last reboot was about two weeks ago, it was running on 5.0.15-1-pve. So I did a reboot, checked the kernel again and now it was on 5.0.21-1-pve. So I did “dkms autoinstall” again, now with success:

Kernel preparation unnecessary for this kernel.  Skipping...

DKMS: install completed.

“modprobe wireguard” now returned no error. I continued the guide with:

echo "wireguard" >> /etc/modules-load.d/modules.conf

Entered my already created Debian 10 container and followed the guide:

echo "deb https://deb.debian.org/debian/ unstable main" > /etc/apt/sources.list.d/unstable-wireguard.list
printf 'Package: *\nPin: release a=unstable\nPin-Priority: 90\n' > /etc/apt/preferences.d/limit-unstable
apt update
apt-get install --no-install-recommends wireguard-tools
ip link add wg0 type wireguard

Edit: To get Wireguard working, I also had to add the TUN device to the containers config, like I did for OpenVPN as well.
You’ll find the config here: /etc/pve/lxc/container_name.conf

lxc.cgroup.devices.allow: c 10:200 rwm
lxc.hook.autodev: sh -c "modprobe tun; cd ${LXC_ROOTFS_MOUNT}/dev; mkdir net; mknod net/tun c 10 200; chmod 0666 net/tun"
