For companies and public institutions, professional portals on the Internet are a matter of course. The private homepage, on the other hand, is a way of dealing personally with the medium. The Internet offers a number of advantages in both professional and private life. From virtually anywhere in the world, the Internet can be accessed via the Smart Phone, e.g. handling of bookings for rail and air travel, etc. When traveling at home or abroad, official and private emails can be retrieved or sent from hotels or Internet cafés via the portal of the domestic network provider. Social media are used in all its facets. Contact is given from far with the office, the family and community in writing, word and picture.

The promotion of a free Internet access awoke my interest in 1996. I first reserved a short, easy-to-remember email address and then attempted to create a homepage with the intention of providing a private area accessible only to people who know the username and password. What is hidden behind it? In my case, it is neither a private lodge entry nor hides behind it immoral thoughts. Should, for example, private documents get lost or be stolen during a trip abroad, the private area could indirectly provide addresses and documents, etc. which could help me to master a critical situation at consulates or police stations.The open area should be under an attractive motto:

Art & Engineering seemed to me to be an interesting topic for a private website.

The development of a private homepage should be done playfully, but the time spent on creating and maintaining the private homepage should not be underestimated. For a taster course, you should use the homepage development aids of your network provider and gradually learn HTML (Hypertext Markup Language) to structure your homepage contents such as texts, images, documents and hyperlinks. For later applications it is always useful to document small functioning program modules over time. With CSS (Cascading Style Sheet), a formatting language for HTML files, it is possible to design sophisticated text and image pages. JavaScript allows browser-side dynamic operations. Learning the language is more complicated and usually represents in a private application a feasible limit. However, tested JavaScript modules taken from the Internet or other sources belong to the module collection of a private website developer. The somewhat professional entry to Internet portals starts with server-side programming in PHP. The use of a PHP-enabled server is charged by some network providers additionally.

For the author of this homepage, the development of a financial calculator and an encryption program for texts and formulas was an exciting challenge. The programming was ultimately a digital playground. The author would like to motivate all visitors to develop new digital applications.
