How to keep duplicate WordPress content out of search engines

Last year I discovered that some of my content had been deleted from Google’s index. After confirming that Googlebot could still access the post in question and excluding every possibility of accidentally blocking Googlebot (robots.txt, firewall rules etc.), I opted to resubmit the post for indexing using Google search console.

OTRS 5 - Unable to fetch email from external accounts

A few weeks back I got a call from a customer who complained that OTRS had been idle for a day without creating any new tickets. After some initial troubleshooting it became clear that OTRS was simply no longer able to retrieve mail.

Gentoo kernel upgrade checklist

These steps are partly dependent on my personal Gentoo installation and should not be viewed as a general recipe. Please refer to the official Gentoo wiki on the topic instead. I’m using genkernel to generate an initramfs and GRUB2 as my boot loader.

Entering the Dark Web

It’s time to take privacy to the next level and ship this website off to the dark web. As a longtime Tor user it has been a source of embarrassment to not have my content available in onionland. However, that’s all in the past and this website is currently available at slackiuxopmaoigo.onion

Most people have probably heard about the Internet of Things (IoT) by now and how these devices are constantly drafted for your friendly neighborhood botnet. My little place on the interweb is currently gaining popularity among my DVR based visitors.

How to build your own kernel on Slackware Linux

With all the noise lately about Dirty COW (CVE-2016-5195) and the lack of patched kernels from Slackware’s “Benevolent Dictator for Life”, I decided it was time to roll up the sleeves and get it done. Since Slackware doesn’t have a “sophisticated” build system and all that grease, it’s a trivial matter to step up to the plate and take responsibility for your own system. I’ll be using “vanilla-kernelversion” as my tag for the kernel and initrd. Also notice that I build my kernels as a normal user.
