Let’s start 5 years before this website came into being: the year 1994 was remarkable in several aspects. In September I was browsing the Internet for the first time, when visiting a colleague in the European Network Center of IBM in Heidelberg. A month later, I read the announcement of OS\/2 Warp, released later that year, which included the TCP\/IP protocol suite and the Internet BonusPak. I remember how enthusiastic I was about the first 32-bit desktop client software with complete Internet connectivity.<\/p>\n
In February 1996 I was writing a computer program and its rationale<\/em>, handling with that year’s leap day. The rationale<\/em> contained several mathematical formulas. It would be the last one without using TeX<\/a>. When working thru The Feynman Lectures on Physics<\/em> I felt again the urgent need to write up some solved exercises in mathematical style (with raised exponents and lowered indices, like in F = G.m1<\/sub>.m2<\/sub>\/r2<\/sup>). I was looking out in the Internet for some tool to accomplish that. End of March I detected Donald E. Knuth<\/em><\/a> on the Web and I learned in particular about his tremendous contribution, the TeX<\/a> typesetting system. His TeXbook<\/a> was on my bookshelf April 1st, 1996.<\/p>\n When I reflected on how to become familiar with TeX, I decided to put my thesis into TeX source format (I soon detected that the use of the LaTeX macro package would be beneficial, sparing me to re-invent a whole lot of formatting work). In 1984-85 I had already typeset a major part of my thesis into SCRIPT, the IBM generalized markup language (GML), making use of the Mathematical Formula Formatter<\/em>. The conversion from GML to TeX was easy and a large part was completed during my summer vacation July 27 to August 22, 1996 in Aquitaine, France, at the Atlantic Ocean.<\/p>\n The TeXification<\/em> task of my thesis was completed in May 1997 and I immediately started to write up some other articles and notes (from the eighties). Under the OS\/2 platform I used emTeX, the TeX implementation of Eberhard Mattes, under Linux the one of Thomas Esser (teTeX). Linux was my preferred platform in 1997.<\/p>\n At the end of 1998 I posted a short note on topological covering theory<\/a> to the preprint server of the AMS<\/a>. Alas, when it was still in the process of being accepted, the AMS announced to shut down the preprint server in February 1999 and I was in trouble and had to look for another way to post it somewhere … but where ? Eventually, I got the idea to have a homepage of my own.<\/p>\n My first homepage was created in June 1999 and posted the 28th<\/sup>. The inital content was just an HTML version of a plain ASCII format article on a Computer program, called gauss.rex<\/a>, that exploits the algorithm for finding the day of the week from a (Gregorian) date. This article is now expanded, explaining Gauss’ calendar formula for the day of the week<\/a>. Next, I added a photo of mine to it, and soon I became more ambitious and in July 1999 I put my thesis<\/a> on the WWW. A section on my computing environment was added in December 1999 after wiring together my LAN at home (this section used to be part of odds and ends<\/a>, but it is no longer published here).<\/p>\n Since then, this website has been restructured at times and regular updates are uploaded to various parts, as I progress with the TeX sources. The original T-Online site was shut down in April 2006, after I had moved to Berlin and established my own domain in February 2006. An enlargement in October 2008 was the documentation of my sailing activities<\/a> with lots of photos. After some tests in January 2010 on my Debian GNU\/Linux server I decided to revamp my site with better navigation and style. In February I put my web pages under the regime of a Content Management System<\/em> (CMS made simple from 2010-2015 and since October 2015 WordPress<\/a>). <\/p>\n","protected":false},"excerpt":{"rendered":" Let’s start 5 years before this website came into being: the year 1994 was remarkable in several aspects.
