After four months of hosting this WordPress blog on a RPi3 I have yet to experience a single issue. No filesystem errors, no kernel oops’s and no hard freezes. Definitely an enjoyable change of pace from the preceding twelve months of hosting this site on a Raspberry Pi 2.

I’ve not been doing any overclocking whatsoever on this device and I believe that to be the decisive factor when it comes to improved stability. My old RPi2 is pretty much useless at this point and I’m guessing it simply got burned out before its time. As for storage, I’m still using a SanDisk MicroSDHC Ultra UHS-I 32GB card.

Configuring and using a generic kernel on EFI-based platforms with ELILO is pretty much an identical exercise to using LILO with legacy systems. Slackware provides you with a mkinitrd generator script to assist in making an initrd image to boot your system.

When I began writing this review there had been 921 days since the last stable Slackware release. The apparent dormant state of development raised a few questions about the health of the distribution, but as usual the rumors of Slackware’s decline was greatly exaggerated.

Some unfortunate but understandable news emerged on the Slackware ARM website today as ARM maintainer Stuart Winter released the following announcement:

This WordPress blog is now hosted on a Raspberry Pi 3 after a year of running on a Raspberry Pi 2. Unlike with the RPi2, I’ve not done any overclocking on this device. I’m hoping that decision will decrease the number of file system related issues and obscure kernel oopses I’ve experienced lately, but I guess time will tell.

The RPi3 is still running Slackware ARM 14.2 and the Linux kernel is at version 4.4.7 at time of writing.

Let’s get ready to rumble: a battle of two Slackware ARM powered webservers.

Hosting your WordPress installation on a RPi2 can be a challenge on multiple levels. Apart from stability issues, my biggest concern is always subpar PHP performance and additional overhead with TLS connections. To determine the potential gain of upgrading my hosting platform to a RPi3, I’ve done a few tests with a MicroSD card I recently retired due to data corruption.

Since I hit the one year mark today I thought I would do a quick update on my RPi2 project. A short recap to kick things off: the project had a rough start due to some overly ambitious overclocking that eventually resulted in severe data corruption. However, after implementing the necessary modifications I enjoyed close to 300 days of easy uptime before a power failure took the RPi2 down. My initial thought after the power failure was that everything was still dandy, but a few weeks later things started to go downhill fast. It all began with a few file system errors:

SimpleScreenRecorder (ssr) is a feature-rich screen recorder for Linux that supports X11 and OpenGL. SimpleScreenRecorder is available as a SlackBuild script from slackbuilds.org, but by only installing the listed dependency, namely FFmpeg, you’ll end up with a rather limited set of supported codecs.

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.

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.
