2022.10.24   General   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).
  streetinfo.lu: 1K clicks in 28 days

2021.07.23   General   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.

2021.05.19   General   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.

Aug 2018   General   Finally it has become a reality: streetinfo.lu: my own .lu domain! Big thanks to the one, who has made this possible!

Jun 2018   General   Due to the kindness of a gentle and friendly man, I had the chance to get an account on the HelioHost "Tommy" server. I made the decision to restart my In the street with my laptop website with a new URL: www.streetinfo.heliohost.org.

Dec 2017   General   Creation of an account on the HelioHost test server "Johnny" and started the In the street with my laptop website with URL www.allu62.heliohost.org, containing informatics related stuff (in particular my Lazarus/Free Pascal applications) as well as information concerning the homeless people in Luxembourg.
