As soon as the basic installation of Joomla has been completed, the setup can be carried out. I had the following problem:  the installer always stopped halfway without warning. The problem was caused by the Apache mod-evasive module. For one thing, there were many 403 errors in the operation of Joomla and new installations could not be set up. For this reason, I first switched off this module:

Log in via SSH and cd to the main directory of your website, e.g .:

sudo -s
cd /var/www/<Your Directory>/web

It's time again. The LTS version of Ubuntu Server 18.04 Bionic receives a system upgrade to LTS 20.04 Focal Fossa. There is no reason to upgrade yet. 18.04 is an LTS version and therefore it will continue to be supplied with system and security updates. In principle, a productive system should not be upgraded prior 20.04.1 version, as a number of bugs will still be fixed by then. This version usually appears about 3 months after publication of 20.04, most probably around mid-July. You can also see this as soon as you try to update:

Why rooting a mobile?

Because it is better. A lot of software available for standard computers is not possible to install because you are just on the user level. Imagine you would be using Ubuntu or Windows and would'nt have the administrator level. With root you may install system relevant software, read system data out of your phone, read logs, install adaway, firewalls or other tools or even install a complete custom firmware.

Is it possible to update the stock firmware after a root?

A clear yes and no. What doesn't work is an OTA update. System updates are simply not possible via OTA, since we have a rooted, custom system. But there is a way to update the phone without losing data. What you need is a rooted Galaxy S8 Exynos SMG950F mobile, a PC and the original charging cable.


During my work with personal computers and servers I experienced a lot of problems. So, whenever I have a problem I try to add the solution here. Due to the mass of problems, I am sure the list is going to grow fast 😏.

Thanks to all the other guys in the www helping also with solutions to the different kind of problems.

Diving schools and instructors generally offer diving training according to proven and globally recognized training standards. Which training is the best? Very idle to speculate. Every training has its advantages and disadvantages, a good training is more dependent on a good diving instructor and good environmental conditions. Not everyone enjoys learning to dive in cold water and with poor visibility. On the other hand, you might want to get to know the theory better and not experience it on a fast vacation course. Basically there are the following training levels, which are also recognized among each other. Below the table you find a list with all courses I teach.

Discover Scuba Diving Try Dive Discover Scuba Diving Try Scuba Try Dive  
Pool Diver  --  --  --  --  
Scuba Diver Basic Diver Scuba Diver Passport Diver / Scuba Diver Elementary Diver / -- Supervised Diver
Open Water Diver CMAS* Open Water Diver Open Water Diver Open Water Diver / Ocean Diver Autonomous Diver
Advanced Adventurer CMAS* + 2 Specialties Advanced Open Water Diver Advanced Adventurer  -- No ISO / EUF Standards
Advanced Open Water Diver CMAS** -- Advanced Open Water Diver --
AOWD + Specialty Stress & Rescue CMAS** + Specialty Stress & Rescue Rescue Diver Diver Stress & Rescue Sport Diver / Club Diver
Master Diver  -- Master DIver Master Diver  --
Dive Leader CMAS*** Dive Master Dive Guide Dive Leader / Dive Leader Dive Leader

This list cannot always be transferred 1: 1. Some courses partially overlap. Depending on which direction you are looking from, this table would look different. Thus, the table can only be a rough guideline. Of course, there are a large number of other associations such as VDST, Protec, Naui, IDA, IDEA. However, they all differ only insignificantly and are based on the training scheme either at the RSTC or the CMAS training track and are usually also a member there, e.g. IAC is a member of the RSTC and CMAS, the BSAC is part of the CMAS and PADI and SSI are pure RSTC members. But no matter what certificate a diver has, there is unfortunately no information about how good or how bad the respective diver is.

This category lists articles about PADI training opportunities. I am teaching all levels of Scuba Diving inlcuding the PADI Assistant Instructor. If you like to do a course (private or small class) with me, check for prices and schedule .

In this category you are going to find descriptions of the Scuba Schools International SSI program. Keep in mind, this is only the standard program. You may do more certifications in other areas of Scuba Diving as well. If you like to do a course (private or in small classes), do not hesitate to contact me:
