How to use Google Fonts locally with the Twenty Fifteen WordPress theme

So this website was pretty much free of trackers with one notable exception, the fonts provided by the Twenty Fifteen theme. By its use of the Google Fonts API, most visitors were still leaking data back to the great chocolate factory. However, as the fonts are open source we’re free to use them outside of Google’s realm.

The hacking of Linux Mint - And out came the wolves

By now most people have gotten up to speed with latest news regarding the attack against the Linux Mint infrastructure and the ripples it created within the Mint community. If not, here is yet another quick and superficial recap:

  • The Linux Mint website was compromised.
  • The Mint forum database containing 145k accounts was sold online.
  • The Mint 17.3 Cinnamon edition was reassembled and bundled with malware.

Raspberry down

Due to a city wide power outage I lost just short of 300 days of uptime on the RPi2. The RPi2 did boot back up when the power returned, but since I had received a new IP address I needed to make a DNS update before the server was reachable again. That’s obviously the downside of running a server on a dynamic IP space, but hey it doesn’t cost me a cent. I have a 300 seconds TTL (Time To Live) on my blog.paranoidpenguin.net A record so I think it’s good enough for a hobby project.

WordPress - Why is WP Super Cache creating suspicious cache folders

The symptom is rather ominous, your wp-content/cache/supercache folder is suddenly populated by additional domain name folders having no connection to your website. What could have caused this? Has your website been compromised or is there some reasonable explanation for this behavior.

Deploying 4096-bit HTTPS on the Raspberry Pi 2 was a bad idea

Who would have thought, right? :-)

After installing my certificate from Let’s Encrypt last week I was immediately confronted with the fact that I had made the wrong choice in regard to key sizes. By using a 4096-bit private key I was relying too heavily on the RPi2’s CPU. This became abundantly clear as page load times were increased by 500 – 1000ms.

HTTPS for WordPress on a Raspberry Pi 2

So you’re hosting your own WordPress blog on a Raspberry Pi 2 and want to join the HTTPS everywhere movement to ensure optimal privacy for your visitors. That’s great, but what kind of performance penalty can you expect as CPU intensive tasks are hardly a favorite with the RPi2. Is the extra computational cost of encrypting data and doing handshakes going to significantly slow down your site? Well, you can probably answer that question yourself as your browser has just loaded this page over a secured TLS connection.
