Rather important site reorganization, with the creation of two new sections: DOS, OS/2 & Windows
Programming, and Old Operating System Software. First, this is more appropriate than the old site structure, because the
corresponding articles do not fit into the Computer Basics section. Second, while playing around with my virtual machines, I try out
lots of applications (especially on old operating systems), and among these try-outs are lots of compilers and interpreters for lots of different programming
languages. A consequence of moving existing files to a new location is that the old links don't work any longer. I created redirects for most of them, but it will
take some time before the search engines will no more list pages with the old links (some of them leding to a "404 Not Found" error). Also, some pages (in particular
the French and German versions of "About myself", "About this site" and the site news) have not yet be updated. Sorry for this little inconvenience!

For the first time, my website reached 1,000 clicks in 28 days in Google Search! For me, a reward for my work, as well as a stimulation
to continue writing programs and tutorials, hoping that the stuff on my site is as much as possible help and/or fun for others. Anyway, thanks to all those, who
have visited or will visit streetinfo.lu (and if you like it, please, sign my guestbook).

It's done (at least partially)! My website is installed on a VPS and thus will stay online during the transition phase,
where HelioHost rebuilds their servers. It was a rather hard work for a non-professional, but being hosted by HelioHost has one very big advantage: the
power of their community forum. Thanks to all those, who helped me with some advice during the last days! For the site visitors, nothing has changed. The
same address (www.streetinfo.lu) and as on Tommy a secure connection with https.

Up from today, all data transfer to and from my site will be encrypted (usage of the HTTPS protocol by default). In fact, all access
via the insecure HTTP protocol is redirected to HTTPS. This ensures, that everybody, that visits the site, will have a secure connection. Thus, new URL:
https://www.streetinfo.lu. One drawback, however: The HelioHost servers use TLS 1.2 and, having a shared IP address, my webserver uses autoSSL, depending on
Server Name Indication (SNI). This means that older operating systems and older webbrowsers (e.g. Internet Explorer 6, standard browser
on Windows XP; not sure if Windows XP is able to connect with Firefox) will no longer be able to access the site.
