Slackware 14.2 review – Last of the Unices

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. The following review is based on the Slackware 14.2 release candidates. Slackware 14.2 x86_64 has been installed and reviewed on a Asus ROG G771JM.

SimpleScreenRecorder on Slackware Linux with multimedia codecs

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

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 A record so I think it’s good enough for a hobby project.

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?

Slackware Linux – Error compiling keymap

I had some issues today with the Akonadi server failing on my Slackware 14.1 box at the office, so I resorted to killing X for a quick revival. However, issuing startx only resulted in the following errors:

Downtime and the perils of Slackware current

I woke up this morning to a mail informing me that WordPress had been upgraded to version 4.4.1. Shortly after I tried to access my blog to verify that everything had gone smoothly, but unfortunately my webserver showed no sign of life. Since I’ve previously had a few hard learned lessons with the RPi2, that made me a bit uneasy. A couple of hours later though, as I was reviewing my logs, the problem became pretty obvious:

Continue reading has switched to eudev

After finally getting my hands on the Black Friday deals from the Slackware ARM Current branch, I have one less device running an old and dormant udev version. My RPi2 spent three hours downloading, installing and upgrading the latest massive batch of packages, which included ripping out udev and plugging eudev back in its place. Instead of rebooting the system I opted to do a “forceful restart” of the device manger and so far it seems we made it out alive.

Slackware Linux is moving to eudev

Some big news was revealed through the Slackware Current (pre-release) changelog today as the switch from udev to eudev was finally announced.

WordPress on Raspberry Pi 2, six months down the road

So the last report from my Slackware based RPi2 hosting project ended on a cliffhanger (pun intended), as I was just recovering after suffering data corruption, the occasional kernel panic and random errors. Suspecting the instability might be caused by my overly optimistic approach to overclocking and overvolting, I decided to turn things down a few notches.
