About this site. |

This site is the personal homepage of a teach-it-yourself programmer, living as homeless in the street in Luxembourg, Western Europe. In fact, there are two
different sites, grouped under one same domain. The reason, why I chose the domain name streetinfo, is because 1. the site and all
its content is created in the street and 2. the site contains INFOrmatics related stuff (programs, web applications and computer tutorials), as well as
INFOrmation (about the homeless life in my country). |

Computing and Programming: Computer Basics. This section, intended for mainstream computer users, contains general computer related information, tutorials, tips and tricks, help texts and problem discussions concerning the every day usage of computers. The section articles are subdivided into 5 domains: System and Security, Internet and Network, Home and Office, Multimedia, Education and Science. It also contains my personal review of common computer software. |

Computing and programming: Lazarus/Free Pascal Programming. This is the main section of my site. Its primary content is the source code (downloadable as open source) and the corresponding executables (Windows 64bit; downloadable as freeware) of console and desktop applications developed with Lazarus/Free Pascal, that I wrote and am writing during these last years. The sources being intended for programmers, of course, the executables may be called free PC applications for everyone, because you find here software of all kinds of domains: Biology, chemistry, computing, electronics, games, geography, languages, mathematics, physics and other. Most of the applications are in English, but for some of them, the user interface and/or data are in French, German, or Luxembourgish. The section also contains a series of tutorials about Lazarus/Free Pascal (e.g. Using MySQL databases with Lazarus/Free Pascal) and tips and tricks, how to realize a given task using this programming language. |

Computing and programming: Website and Database Applications. Another programming related section. You find here my online applications, mostly created with Perl CGI (some are written in PHP or Javascript) and, if there is a database involved, MySQL. All online applications are entirely free to use; for some of them, the source code is also available. Among them, there are two huge projects: AnimalDB ("Tiere-Datenbank", my personal animal database; in German) and a Luxembourgish course (project actually abandoned and removed from the site; in French). As for the desktop programming section, you also find here theoretical background articles: tutorials about web development (e.g. Setup of a web development environment on MS Windows) and website programming tips (HTML, CSS, Javascript, PHP, Perl CGI, multimedia). |

Learning: Mathematics, Science and Sysadmin. Planed as a small section with mathematics and science articles, that are not in relationship with computers, its content was extended in February 2022 by adding a new sub-section called Computer Administration, where I publish computer system and network administration related tutorials, based on the experiences made when setting up a VMware network with machines running various operating systems. |

Biology Computing and Bioinformatics. This project, that I started in 2016, pausing it after (for the fourth time) my laptop was stolen by those people, from whom our social services tell us, how important it would be, to be there for them, may be seen as a part of the computing site, or, because of its size and its specialized content, as a third site at the streetinfo.lu domain. The idea was to write a series of articles, explaining the fundamentals of classical, molecular and population genetics, mathematical biology and bioinformatics, as well as to create a library of Perl modules, programs and example data, that may be used to resolve biology related problems. Not always being easy to do informatics, when living in the street and lots to do with my Windows and web applications, it is uncertain, if I ever get the time to review the articles and the code and get ready to start publishing the project. |

Homeless Life in Luxembourg. Nothing to do with computing, but lots with me and my life. My "SDF" site contains articles and little stories, written during my homeless situation, in particular texts, dealing with my fight for respect and human dignity, the actual situation in the social centers (where the guys from here not only loose more and more all these basic services, that were for us before, but also have less and less possibility to go there, without being forced to endure noise and bugging, without having to fear for their stuff and even for their bones) and my lived experiences with the so-called "normal people" and our modern society. You also find here contact information and website links of all major homeless related social services in Luxembourg and links to homeless and society related articles, published on the Internet. An idea in mind is to give homeless people the opportunity to use the site, in order to tell their own life-story and their own experiences with our social system, as well as to publish the opinions and experiences of people working at the social institutions and the results of personal public-opinion polls. Uncertain project for the future… My social site is in French, some of my little stories being in Luxembourgish, German, or English. |
