<p><i>Every month the column <a
|
||
href="http://www.fsfeurope.org/activities/education/tgs/tgs.en.html">TUX&GNU@school
|
||
[2]</a> reports about free software, a homepage on the topic
|
||
and an easy to implement idea. This month I talk about <a
|
||
href="http://bioinformatics.org/ghemical/">Ghemical [3]</a>,
|
||
modelling und computing molecules, about <a
|
||
href="http://www.seul.org/edu">seul.org/edu [4]</a>, the
|
||
education portal of SEUL - Simple End-User Linux and about
|
||
the idea "word games generated rapidly".</i></p>
|
||
|
||
<p>Welcome to the 4th edition. As I promised last time, there
|
||
are some news today. This is the first edition released under
|
||
the roof of the <a href="http://www.fsfeurope.org">Free
|
||
Software Foundation Europe [5]</a> and <a
|
||
href="http://www.gnu.org">GNU [6]</a>. In this context
|
||
TUX&GNU@school will be released in different languages in
|
||
the future but right now only in German and English. At this
|
||
point I want to thank Christian Selig and Kristian Rink for
|
||
their support with writing and translating. Unfortunately
|
||
there is no report about a school using GNU/Linux and/or Free
|
||
Software in this edition. I hope that next time I find
|
||
somebody and I likewise will upgrade the <a
|
||
href="http://www.edux.ch/nav.php?site=99">Questions Page
|
||
[7]</a> and translating of course. And again, sorry for the
|
||
latenese. The reason is easy: It a lot of work (too much for
|
||
a hobby) promoting and installing (!) GNU/Linux at Swiss
|
||
schools. But now we're talking about a topic everyone loves:
|
||
Chemistry.</p>
|
||
|
||
<h3>Ghemical - Modelling and computing molecules</h3>
|
||
|
||
<p><a href="http://bioinformatics.org/ghemical/">Ghemical
|
||
[3]</a> is a free program for chemistry, which is relatively
|
||
easy for modelling and computing molecules. I tssted the
|
||
version 0.82 under <a href="http://www.debian.org">Debian
|
||
GNU/Linux 3.0 [8]</a> and <a href="http://www.kde.org">KDE
|
||
2.2.2 [9]</a>. You can easy install the program under Debian
|
||
with the command <tt>apt-get install ghemical</tt>. Version
|
||
0.90 is up to date and if you can trust the homepage, they
|
||
want to release the version 1.0 in this summer (that's
|
||
becoming scarely) or autumn. The program is (and was)
|
||
developed by several people, all listed alphabetically on the
|
||
homepage.</p>
|
||
|
||
<p>Before I begin with the introduction to Ghemical I want to
|
||
mention yet: Unfortunately my last chemistry teacher took my
|
||
interest for this subject so I can't interpret all terms
|
||
correctly. But who is bothering intensifiedly with this
|
||
subject will understand it much better. That's the reason why
|
||
I'm not going in the depth of each term and function.</p>
|
||
|
||
<p>Starting the program a window quite similar to the first
|
||
screenshot will appear. That's the main window from where you
|
||
appoint what will be the project you work on. Up to now
|
||
quantum and molecular mechanic models and reduced protein
|
||
models are available whereas the last one isn't completely
|
||
implemented yet. When you start Ghemical it is most useful
|
||
doing this out of a terminal because it is still necessary to
|
||
make some in- and output on the terminal. But this feature
|
||
shall disappear with the version 1.0. Working with the
|
||
program the menu panel and the popup menu are the most
|
||
important aids. The menu panel owns three items: <i>File</i>,
|
||
<i>Windows</i> and <i>Help</i>. It's important to mention now
|
||
the program isn't really translated to German. There are only
|
||
scattered terms, words and descriptions in German. In the
|
||
menu item <i>File</i> you can open projects, load already
|
||
existing ones and exit the program. At <i>Windows</i> it is
|
||
possible to choose between the following three MDI modes:
|
||
<i>Notebook</i>, <i>Toplevel</i> and <i>Modal</i>. And
|
||
finally in the last item <i>Help</i> you find either general
|
||
information about Ghemical or a link to the
|
||
documentation.</p>

|
||
<br />
|
||
|
||
|
||
<p>If you decided for a project at the left brink are a lot
|
||
of modification possibilities to work with. These differ from
|
||
different rotation and translation directions over the
|
||
zooming unless the erasing and adding of atoms and bindings
|
||
of course. Clicking on the prompt window for the molecules
|
||
with the right mouse button a popup menu appears which
|
||
contains different items depending on the project. To mention
|
||
are for instance the different presentation possibilities.
|
||
Proceeding the single atoms can be indexed differently.
|
||
Surely it's interesting too that you can plot the molecules
|
||
in different ways among others there is a display for 3D
|
||
glasses build in. This popup menu contains then too the basic
|
||
functions for saving and closing the projects. The choice
|
||
between between different elements and bindings is possible
|
||
here too. Beneath these simple function there are more
|
||
complex ones too. <b>Where the correct adding of hydrogen
|
||
atoms every reader still understands menu item as
|
||
"ESP-colored vdW-surface" isn't only imcomprehensible for the
|
||
author.</b> At this item the interested user and ongoing PhD
|
||
will hopefully understand it. Principally there is a huge
|
||
number of different engines and algorithms for studying and
|
||
changing the molecules. They seem to be quite professional
|
||
for me as layman. The possibility of generating DNA molecules
|
||
out of an easy "ACGT code" is absolutely noticeable for
|
||
me.</p>

|
||
|
||
|
||
<p>At the end some tips (mainly from the <a
|
||
href="http://bioinformatics.org/ghemical/">homepage [3]</a>)
|
||
that can help you with the daily usage.</p>
|
||
|
||
<ol>
|
||
<li>For the generation of a quantum mechanic model
|
||
principally it is more meaningful to generate a molecular
|
||
mechanic one first which then you can transform in a
|
||
quantum mechanic one.</li>
|
||
|
||
<li>All menu panel are freely relocatable and placeable
|
||
outside of the main window too.</li>
|
||
|
||
<li>There are a lot of import and export formats available
|
||
for molecular mechanic models.</li>
|
||
|
||
<li>If you are forced using Windows at work then you can
|
||
find a <a
|
||
href="http://bioinformatics.org/ghemical/cygwin.html">detailed
|
||
description [10]</a> about the usage of Ghemical under
|
||
Windows.</li>
|
||
</ol>
|
||
And for those who are still wondering at the end of this
|
||
short description how you have to pronounce "Ghemical" can
|
||
find an answer in the statement of an developer which says
|
||
that generally everybody can pronouce it as he or she want
|
||
but the "G" comes from "GNU" and/or "GNOME". <br />
|
||
<br />
|
||
|
||
|
||
<p>But now continues to the home of Simple End-User
|
||
Linux.</p>
|
||
|
||
<h3>seul.org/edu, the education portal of SEUL - Simple
|
||
End-User Linux</h3>
|
||
|
||
<p><a href="http://www.seul.org/edu">SEUL/edu [4]</a>
|
||
subproject of <a href="http://www.seul.org">SEUL [11]</a>
|
||
stands for "Simpel End-User Linux". The goal of SEUL is
|
||
making available an as easy as possible GNU/Linux system for
|
||
every user. Thereby qualitatively good software shall arise
|
||
which preferably will be released under the terms of the <a
|
||
href="http://www.gnu.org/copyleft/gpl.html">GNU GPL [12]</a>.
|
||
To manage and assist this the site is hosting a lot of <a
|
||
href="http://www.seul.org/pub/hosting.html">projects [13]</a>
|
||
and makes available mailing lists for the coordination of the
|
||
work. Main language in this project and on the website too is
|
||
English.</p>
|
||
The subproject school and education was founded in 1998. Doug
|
||
Loss is the leader at the moment and Karl Pe<50>a is managing a
|
||
lot of stuff on the <a href="http://www.seul.org/edu">website
|
||
[4]</a>. Beneath these two there are a lot of other
|
||
freelancers too. In principle SEUL/edu mainly consists of a
|
||
mailing list whose access is already described on the
|
||
frontpage and you can subscribe right there too. <br />
|
||

<h5>Screenshot 3: The homepage of SEUL/edu</h5>
|
||
<br />
|
||
<br />
|
||
|
||
|
||
<p>The homepage of the project is devided in seven sections.
|
||
They are: <i>Current projects</i>, <i>Existing software</i>,
|
||
<i>Case studies</i>, <i>Documentation</i>, <i>Regular
|
||
reports</i>, <i>List archive</i> and <i>Links</i>. There is
|
||
only one <a href="http://seul.org/edu/projects.html">project
|
||
[14]</a> now under the first item whose goal it is making
|
||
available an ISO-Image containing a counterbalanced
|
||
collection of education software. But the development stands
|
||
still at the beginning and we will see what will happen with
|
||
it. However the database with already <a
|
||
href="http://richtech.ca/seul/">existing software [15]</a> is
|
||
remarkable by all means and I never saw such a big one in the
|
||
internet yet. At the moment the database contains 518
|
||
software projects arranged by categories believe it or not.
|
||
There is a short description for each entry. Additional and
|
||
optional information are: version, date, author, homepage,
|
||
download URL and the used license of course. Accessorily it
|
||
is possible showing only predetermined data as the license or
|
||
a the short description. Important for the further growth is
|
||
the easy way to enter new software which is accomplished
|
||
through a <a
|
||
href="http://richtech.ca/cgi-bin/seul/seuladd0.pl">form on
|
||
the website [16]</a>. You can search the entries either for a
|
||
destined application or a pretermined word. But don't forget
|
||
there is not only Free Software in this database. Because the
|
||
people of SEUL/edu collected and catalogued already so much
|
||
software it would possibly make sense that other projects use
|
||
this database too, integrating it in their webpages and
|
||
expand it. A translation in other languages would expand the
|
||
circle of possible users again.</p>
|
||
|
||
<p>They who are searching reports about schools using
|
||
GNU/Linux and/or Free Software making a find here too.
|
||
SEUL/edu offers <a
|
||
href="http://casestudy.seul.org/cgi-bin/caseview0.pl">reports
|
||
[17]</a> of more than 50 schools worldwide. There are a few
|
||
from Cuenca in Ecuador to Marl in Germany. It is possible to
|
||
easy make new entries with a <a
|
||
href="http://casestudy.seul.org/casestudy.html">form [18]</a>
|
||
on the website. Under <a
|
||
href="http://seul.org/edu/docs/">documentation [19]</a> you
|
||
don't find as much at the moment. There is already a
|
||
classification for the documenation in the future which
|
||
contains sections as the <i>Users guide</i> or the
|
||
<i>Teachers guide</i>. Even a category helping
|
||
decision-makers and people who want to persuade schools of
|
||
GNU/Linux and/or Free Software is available. But SEUL/edu
|
||
lists <a
|
||
href="http://seul.org/edu/docs/relateddoc/index.html">foreign
|
||
documentation[20]</a> in the same structure too. At the
|
||
moment there is a helping description for people who want to
|
||
write documentation for one of the named categories.</p>
|
||
|
||
<p>The project itself releases an extensive report about the
|
||
situation of GNU/Linux and Free Software in and at schools at
|
||
least twice a month. The since the beginning of 2000
|
||
published reports are of course archived on the site <a
|
||
href="http://seul.org/edu/reports.html">[21]</a> so that
|
||
everyone can read them at any time. Because SEUL/edu mainly
|
||
works and communicates over the mailing list they made an
|
||
archive of the list available <a
|
||
href="http://archives.seul.org/seul/edu/">online [22]</a>
|
||
too. And finally under the last item you can find an
|
||
extensive <a
|
||
href="http://seuldat.seul.org/cgi-bin/link/urlview.pl">links
|
||
collection [23]</a> to further sites about the theme
|
||
"GNU/Linux, Free and Open Software in and at schools".</p>
|
||
|
||
<p>But now, let's continue with the idea of this month.</p>
|
||
|
||
<h3>"Word games generated rapidly"</h3>
|
||
|
||
<p>For the last idea, concedely a little skinny one, I didn't
|
||
receive any implementation because of this continues to the
|
||
idea of this edition. Because the ideas introduced until now
|
||
were always more or less for learning or teaching at the hard
|
||
everyday school life I want to present an idea for loosing
|
||
today. Riddles, an invention fascinating and entertaining
|
||
humankind since billions of years, can prettify school a
|
||
little. Even children find pleasure and happiness with
|
||
riddles and guessing games. I think about a quite special
|
||
kind which seems to be rather simple to implement and program
|
||
too. What I mean is a letters huddle containing different,
|
||
mostly thematically coherent words. The task is to search and
|
||
find these words in the mix-up. Mostly the letters are
|
||
disposed in an rectangle in which the to finding words are
|
||
placed horizontally, vertically or diagonally. Thereby the
|
||
searching words can be written forward or backward.</p>
|
||
|
||
<p>Perhaps there is already a piece of software generating
|
||
such riddles. And if not such a thing would be implementable
|
||
in short time, isn't it ? A little bash script putting words
|
||
of a definite category into a letters huddle. Writing this
|
||
letters sequence with some <a
|
||
href="http://www.latex-project.org">(La)TeX [24]</a> commands
|
||
into a text file and translating it would result in a quite
|
||
good-looking riddle for pupils her excercices already
|
||
finished. And the best, if you select correlatively the word
|
||
collection pupils even learn the correct orthography or
|
||
understand the context between the single word families.
|
||
Anyway I'm curious about the ideas you will create. Farther
|
||
ideas were for instance that words are written correctly and
|
||
wrong in the letters mix-up or you make the whole thing with
|
||
numbers.</p>
|
||
|
||
<p>Once again at this place the calling to send <a
|
||
href="mailto:foxman@lugo.ch">me [1]</a> ideas which you think
|
||
are easy to implement or you didn't find comparable software
|
||
yet, then I will report about them at this place in one of
|
||
the next editions. And perhaps there are firms, schools or
|
||
single persons offer a reward for an implementation.</p>
|
||
|
||
<p>But now continues to a new section.</p>
|
||
|
||
<h3>News and up to date program versions</h3>
|
||
|
||
<p>In the future I will report in this section about news of
|
||
GNU/Linux and Free Software at school. Beneath I will list
|
||
actual program versions of free education software for the
|
||
moment only of the programs I already reported about in
|
||
TUX&GNU@school. Software whose version changed since the
|
||
last edition will be highlighted in red.</p>

|
||
<p>On 6th of september Raphael Hertzog announced the birth of

href="http://www.debian.org">Debian [8]</a>. Interim goal of
|
||
the project is it making Debian the best available
|
||
distribution school purposes. At the moment they impetuously
|
||
dicuss on the <a
|
||
href="http://www.debian.org/MailingLists/subscribe">mailing
|
||
list [25]</a> how they want to go on the first tasks and what

<h4>About the author:</h4>
|
||
|
||
<p>Mario Fux finished 1999 the PrimarlehrerInnenseminar in
|
||
Brig after he made up mathematical and natural scientifical
|
||
matura. In a body with two colleagues he founded the <a
|
||
href="http://www.edux.ch">"ALIS - Arbeitsgruppe Linux an
|
||
Schulen"</a> (Swiss work group for linux at school).
|
||
Meanwhile he studies at the <a
|
||
href="http://www.ethz.ch">Swiss Federal Institut of
|
||
Technology Zurich</a> <a
|
||
href="http://www.ee.ethz.ch">informations technology and
|
||
electrical engineering</a>. And if he once doesn't spend his
|
||
time in front of the PC, he sits at his nature pond in the <a
|
||
href="http://www.randa.ch">mountains</a>.</p>
