In the street with my laptop

About this site.

Concernant ce site (version française de cette page) Über diese Website (deutsche Version dieser Seite)

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: 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 is subdivided into 5 subsections: System and Security, Internet and Network, Home and Office, Multimedia, Software. Among these, the Software subsection is somewhat special, including my personal review of common computer software, as well as tutorials about the installation and usage of development and other software on different platforms. All articles are in English.

Lazarus/Free Pascal Programming: Puzzle for kids PC application   Computing: 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.

Website and Database Applications: HTML and Free Pascal color picker online application   Computing: Website and Database Programming.
Another programming related section. Here you find 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, actually dormant; 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. Articles are in English, online applications may be in other languages.

    Computing: Computer Administration.
This section, intended for more advanced computer users, contains computer system and network administration related information, tutorials, tips and tricks, help texts and problem discussions concerning virtualization with VMware Workstation, operating system installation and configuration, and computer networks. The section is subdivided into 7 subsections: VMware, Windows, macOS, Linux, DOS, Other OS, Network. Not for professional computer administrators, but for people who want to learn new stuff, or who search for an answer to a question or problem that occurred when working with an operating system or some network components. All articles are in English.

    Learning: Mathematics and Science.
An (actually very small) section with mathematics and science articles, help texts and calculation examples, not in relationship with computers. The section is subdivided into 5 subsections: Mathematics, Physics, Chemistry, Biology and Electronics. All articles are in English.

Homeless Life in Luxembourg: My fight for respect and human dignity   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.
