Have you ever used a hallucinogenic drug in your life? If so, then the following video might put a smile on your face because this “digital LSD” really works. See for yourself. But this experiment is perhaps even more fun for people who have never used any hallucinogenics, but are perhaps a bit curious to find out what the effects are a bit. But no worries, you won’t have to take any drugs. The only thing you need to do is watch the following video, and once you hear the voice say that you can look away then you should watch any direction in the environment you are in. What you see then only lasts a couple of seconds so make sure you look around you. This effect is the result of tricking our eyesight by the technology that is used in the video.

In my previous post I explained how to setup an OpenVPN server on Raspbian (April 2018 release) on any model Raspberry Pi. Here’s how to setup the client certificates that you can import in your OpenVPN client app on your desktop or mobile. All these commands are to be entered in the console as root user.
cp /usr/share/doc/openvpn/examples/sample-config-files/client.conf /etc/openvpn/client/client.ovpn
Edit the client configuration file client.ovpn and make sure the options as shown below are set.
tar cJf /etc/openvpn/client/client.tar.xz -C /etc/openvpn/certs/keys ca.crt client.crt client.key ta.key -C /etc/openvpn/client/ client.ovpn
You should now have a zipped file called client.tar.xz in the directory /etc/openvpn/client. This is the file you need to download or copy using a flash USB drive or whatever means, and import it on the device that has the OpenVPN app and from where you want to connect to your OpenVPN server.
This weekend I heard a friend say that he wants to turn his Raspberry Pi into a VPN server. Since I still had an old Raspberry Pi laying around I decided to install the latest version of Raspbian on it (April 2018 release) and also install OpenVPN on it, record how I did this, and show my friend how he can easily do the same on his Raspberry Pi. I listed all the commands I use in the video on this page here below.
I’ve been using the public Google DNS servers 22.214.171.124 and 126.96.36.199 for several years now. It was once said that using these DNS servers would result in a noticeable speed increase when compared with the DNS servers that your internet provider makes you use. I started using the Google servers and the addresses immediately got stuck in my head, so I haven’t stopped using them since. Until today that is…
I’ve always really liked the easy-to-remember, and simply awesome addresses 188.8.131.52 and 184.108.40.206. I was happy with the response times and I never had any issues or complaints either. So why change? I’d better have a damn good reason for making this choice! Well, obviously I do!
Yesterday somebody told me that he switched to 220.127.116.11 as primary DNS server and 18.104.22.168 as secondary. He also mentioned that the response times are fast af! That info immediately drew my attention. So I decided to further investigate this as soon as I would get home. Turns out that these servers are indeed fast and have good testing results. I also learned that the good people at CloudFlare are behind it (Wiki). I’m pretty sure that remembering these new server addresses will not be a problem either.
I’m looking for speed when it comes to DNS servers. I want to use the fastest DNS servers in existence. The more speed, the better. Naturally I also want them to be reliable, safe, and respecting my privacy. It turns out that 22.214.171.124 & 126.96.36.199 are all these things and more. So I will be saying my goodbye’s to 188.8.131.52 & 184.108.40.206. And at the same time I will be welcoming 220.127.116.11 & 18.104.22.168 with open arms. Would you like to learn more? Or do you need a step-by-step guide on how to change what DNS servers you use? Just visit the website.
I have Ubuntu16.04 servers running and I want to run database engines like MariaDB on it. Normally I would just type sudo apt install mariadb-server and the database system would be up and running in under two minutes. Ubuntu16.04 will install version 10.0 by default, but I want to install a different version. At the very least 10.1. Why 10.1 you might ask? Well because 10.1 was the first release that had Galera included by default in the package. Galera is a gift from the gods for all system administrators, developers, backup operators and other people who work with databases a lot. With three nodes, the minimum, it will offer you fast and reliable database synchronization and redundancy. Galera is a solid foundation for an easy to build load balancing environment. But first of we will install the MariaDB 10.1 instance on a clean Ubuntu16.04 server. If you want to be absolutely certain that the instructions below will work flawlessly for you, I would advise to use a clean fresh installed server also. Please remember that upgrading (or downgrading) from a different release version is NOT a good idea. When I was learning this the hard way I did a lot of reading on the subject and I can safely say that you should not follow these instructions on a system that runs, or used to run a MariaDB or MySQL instance. Even if you have removed it first apt remove you are still at risk of running into problems. When I was having problems with this I tried many things that included killing the process: kill -9 $(pgrep mysql) and then purging the removed packages apt purge and also apt autoremove and I even had to delete some left-over files manually. Don’t even try to install it on a system that ran a higher version > 10.1 because that will be guaranteed imminent failure. You’ve been warned! Let’s get started and install some required software and updates.
sudo apt update && sudo apt upgrade
sudo apt-get install nano ssh openssh-server software-properties-common rsync

Without me knowing beforehand I apparently just watched the series finale episode of The Middle. I started to suspect that something was off when I noticed that it was a 2-in-1, in other words a 40-minute episode. Somewhere during the second half it became pretty clear that this was going to be a wrap. My initial response to this was: NOOOO! Here’s a short interview with the cast after the recording of the final episode.
The Middle was not my all-time favorite sitcom, but I did enjoy it very much. If I would have to make a list with my favorite sitcoms that I am currently watching it would make it to a top-10 list. I’ve always been a very loyal fan and so I just realized that I’m really going to miss the Heck family. So farewell Mike, Frankie, Axl, Sue and Brick. Thanks for all the entertainment over the years. I’m gonna miss you guys! There’s a short video made by Patricia Heaton, the actress who plays Frankie, where she talks and cries about the final recording and the wrap on her Instagram.
“Zet zaterdag 30 juni maar in je agenda, want dan sta jij te hakken in ’t Leijpark!” Yes I know!! And YES I will. Yes yes. I gotz the tickets in mah pocketz. Can’t wait!! WOOT! If it’s going to be anything like it was last year, we’re in for a really good time! Silly Tilburg, with your silly after-and-90’s parties. I love you Tilburg! Cu soon old friend!
Have a look at the gaming room of this guy. He is actually one of the people who used to work for Sierra back in the 90’s. Or in other words, the glory days of gaming. I’m só jealous of this guy’s collection. I also want this also! I NEED THIS!! I REALLY NEED THIS BECAUSE OF REASONS!! I hate this guy so much right now. Not really of course 😉 Or do I? Ah well. I guess I should be happy with my collection as it is. It fits in one cupboard in my living room. Today I actually re-arranged some things while I was cleaning, and connected some equipment because I want to have it all set and in order for when I decide to some oldskool gaming. So earlier today I was feeling content and happy about the results and my collection as it is. Until I saw this video that is.. I seriously need more “real-life” currency so I can also start expanding my collection. In the near future I should go find for a new place to live where I can build my own game room that will be the same size as my whole apartment is at the moment. So, give me money!! You need to give me some money. It’s very important. I have an idea.. please click the following link and just follow the instructions. It will only take a minute. Thanks in advance! http://bit.ly/2HqGCd8. Now watch this fun video.
