Despite my problems with all these so-called normal people, trying to continue with my site. New Animal database
feature available: Primates fotoalbum.
The thieving of my vital things has ended as it started. But my hell on earth is far away from being over: Several times per day, passing one or more
hours like cattle outside in the rain, because more and more young people use my squat as their place to consume their alcohol and joints. And last night,
another time, that I slept in the entry of a shop, because the snoring of a more or less drunk immigrant, who considers my home as his place, too, didn't make
it possible to close my eyes just for half an hour. Tired and weak, headache and pain in the members, desperation and hopelessness. More and more hating myself that
I started this site, that I believed in myself and in the future, that I am as I am...
The most often viewed page on my site during the last year is my tutorial concerning the connection to MySQL using Lazarus / Free Pascal. This text
is rather long and detailed, but only deals with the connection itself, just reading a count value from the database, but not showing at all how to
proceed to retrieve the field values from a multi-rows returned dataset. Published a new tutorial dealing with reading
data from a MySQL database using Lazarus / Free Pascal. in the Lazarus/Free Pascal project
section. The text shows the similarities between ordinary file reading and database select and also tells you what you have to do in order to correctly
handle UTF-8 data.
Review (with some corrections) of my Web development environment setup on MS Windows tutorial published in the
Web and Database development section. The part, concerning Perl, has partially been
rewritten, in particular the paragraph concerning Using Komodo Edit as Strawberry Perl editor: Beside giving
details about running command line scripts and using pod2html to display context help on Perl buildin functions and Perl modules, there is
now a proper solution to run Perl CGI (and PHP) scripts from within the editor. This thanks to a Free Pascal command line utility, written
primarily for my actual development environment, but that can easily be adapted by choosing custom settings in a configuration file.
Another text in the Society and social system section: New very negative experiences with our social institutions:
"Streetwork Uewerstad" revisited: A sad déjà-vu!
New Lazarus/Free Pascal GUI application, another algebra trainer (exercise generator), available: Column addition and subtraction.

calculation by hand using this method.
There is also a new version of my Word-search puzzle application: diagonal words may now be displayed from left to right as well as from right to left, the words on any line may be inverted; these new possibilities should largely increase the difficulty (and the interest) of the game.
New text in the Experiences and reflexions section: Description of the nightly agression by two
Arabs and other experiences with the migrants, as well as general reflexions concerning immigration in Luxembourg: "I
am an immigrant! I have rights!"
My website offline for a month; things, that happen, without you can do anything but being patient and waiting: a harddisk
crash on the HelioHost Tommy server, the need for them to replace it, to back up all user data, to rebuild the system. The need for me to create a
new account, to restore my home directory and the MySQL databases. Actually on Ricky, not all working again, in particular AnimalDB actually unavailable!
Really not easy to keep the mood for working. My situation becomes more and more difficult and I'm not sure if my site will have any future. After the problems withs the pupils and their drugs, after the insults and threats of Monsieur K. and his clique, agressed and rubbed by two Arabs, told at the place, where I used to work on my website (and where I gave out some 25€ per week for coffee and bread), that the people don't want me with my laptop on the terrace and now every few days, something stolen or busted: my umbrella broken, my rain-jacket disappeared, my coffee-thermos, my bread, butter and cheese stolen. If you live from the only money, that kind people offer you, these things are vital... Jealousy, narrow-minded and primitive prejudices, hatred against everyone, who's not exactly like them, terrorized for the only reason, that I am different! You might also call it the thank of this country and its citizens for nearly 20 years of work (and tens of thousands of euros of taxes, they have profited of by one or the other way)!

Insulted, robbed and beaten by Arab drug dealers in Luxembourg-City, now chased off the place in the north of the country, where I thought having finally
found a home by the drug kids of the school nearby. No idea why drugs are so important for this country, that people, who work or have worked here, must
accept to let terrorize themthelves by those, who sell or consume grass, marihuana or cocaine. Passing the whole week outside in the rain, waiting
that school is over and that I can return to my squat, something between impossibly difficult and really impossible not to entirely loose hope and getting
The description and download files not yet available, the application itself is accessible since this afternoon on my site ... and personally I find
that it's really not bad!
There is no particular place on my site previewed for publishing science related documents; I finally decided to do them in the Computer basics: Science and Education section. What's even not so wrong: First, these texts

Luxembourgish spellchecker in LibreOffice".
Started with a new and ambitious web and database project: The publication of a
Luxembourgish online course. Seen in relationship with the linguistic situation in my country, it's all in French. Translation
to other languages would be nice, but from the point of vue time, that is simply impossible. It's just at its beginnings and it will
take before it will really be usable. To get a first impression, take a look at lesson 1 (leçon 1). The text/grammar part is ready and
the way that all following lessons will be. I hope to publish the theoretical initiation to pronunciation, orthography and grammar
as well as the first exercices during the coming weeks.

the texts already published before, I started with the Society and social
system part: A longer very personnel view of the so-called "Stëmm vun der Strooss" (Voice of the street).
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 a laptop" website with a new domain name:
Crash of the "Johnny" server and the need to entirely rebuild it. My website down for over a month. In a mood fluctuating
between resignation and new hope, I continued to develop Lazarus/Free Pascal programs and writing homeless related articles.
|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.|
