From Zero to a mail server with Postfix Dovecot and Roundcube installed in less than half an hour

When setting up mail servers in the past, the longest part has always been creating the configuration files for each of the services. I had a look around for a script, but could only find ones for Debian, so I decided to take one of them and convert it for Centos 6. I prefer running Centos because of how long the support for it is, which then makes there be less chance of any updates breaking the server. There are probably still some bugs in the script, but it is finally at a stage where it can successfully set up the services on a Centos 6 minimal install.

The script is at:

Blender animation - Particles affected by music in cycles animation at 720p 60fps

I didn't even know that this animation would look this way, so it is really just an experiment, rather than something that was properly planned. This version of the animation was rendered at 1920x1080, so that is the only size that will run at 60 frames per second. There is also a version of this video that I scaled down to 1280x720, so that you can still see the 60 frames per second if you have an older machine.

Installing Exchange Server 2016 onto a Windows Server 2016 virtual machine

This is a video showing how to install Exchange Server 2016 onto Windows Server 2016, with all of the steps involved onto an updated system. I have shown the whole of the recording, so that you can see how long it did take, but I did speed up some of the longer bits. You can see how long the whole process did take by looking at the clock in the bottom right of the Windows desktop.

Installing Windows Server 2016 onto Qemu with Virtio drivers and hugetlbfs

In this video I am installing Windows Server 2016 onto Qemu and am using the virtio drivers to hopefully speed things up. The install has been recorded twice, because I ran the second install in Qemu using memory backed by hugepages, which is supposed to increase the speed of the virtual machine, by using memory pages that are larger. I have also superimposed a timer on the video so that it can be easier to time what is going on.

iRedmail on Centos 6 with over 2 million users

I said that I would try to install over 2 million users onto another email system and the one that I used is iRedmail. It is a system based on Postfix, Dovecot, Roundcube and Amavisd that is installed with a simple script. You will not find a load of un-needed features on it, because it has been designed to just get the job done, rather than to be bloated out with features, so that some salesmen can try to extract even more money from some over-rated enterprise companies, who were helped by slavery.
