  8. <h1>TUX&amp;GNU@school - 4th edition</h1>
  9. <p><i>Every month the column <a
  10. href="">TUX&amp;GNU@school
  11. [2]</a> reports about free software, a homepage on the topic
  12. and an easy to implement idea. This month I talk about <a
  13. href="">Ghemical [3]</a>,
  14. modelling und computing molecules, about <a
  15. href=""> [4]</a>, the
  16. education portal of SEUL - Simple End-User Linux and about
  17. the idea "word games generated rapidly".</i></p>
  18. <p>Welcome to the 4th edition. As I promised last time, there
  19. are some news today. This is the first edition released under
  20. the roof of the <a href="">Free
  21. Software Foundation Europe [5]</a> and <a
  22. href="">GNU [6]</a>. In this context
  23. TUX&amp;GNU@school will be released in different languages in
  24. the future but right now only in German and English. At this
  25. point I want to thank Christian Selig and Kristian Rink for
  26. their support with writing and translating. Unfortunately
  27. there is no report about a school using GNU/Linux and/or Free
  28. Software in this edition. I hope that next time I find
  29. somebody and I likewise will upgrade the <a
  30. href="">Questions Page
  31. [7]</a> and translating of course. And again, sorry for the
  32. latenese. The reason is easy: It a lot of work (too much for
  33. a hobby) promoting and installing (!) GNU/Linux at Swiss
  34. schools. But now we're talking about a topic everyone loves:
  35. Chemistry.</p>
  36. <h3>Ghemical - Modelling and computing molecules</h3>
  37. <p><a href="">Ghemical
  38. [3]</a> is a free program for chemistry, which is relatively
  39. easy for modelling and computing molecules. I tssted the
  40. version 0.82 under <a href="">Debian
  41. GNU/Linux 3.0 [8]</a> and <a href="">KDE
  42. 2.2.2 [9]</a>. You can easy install the program under Debian
  43. with the command <tt>apt-get install ghemical</tt>. Version
  44. 0.90 is up to date and if you can trust the homepage, they
  45. want to release the version 1.0 in this summer (that's
  46. becoming scarely) or autumn. The program is (and was)
  47. developed by several people, all listed alphabetically on the
  48. homepage.</p>
  49. <p>Before I begin with the introduction to Ghemical I want to
  50. mention yet: Unfortunately my last chemistry teacher took my
  51. interest for this subject so I can't interpret all terms
  52. correctly. But who is bothering intensifiedly with this
  53. subject will understand it much better. That's the reason why
  54. I'm not going in the depth of each term and function.</p>
  55. <p>Starting the program a window quite similar to the first
  56. screenshot will appear. That's the main window from where you
  57. appoint what will be the project you work on. Up to now
  58. quantum and molecular mechanic models and reduced protein
  59. models are available whereas the last one isn't completely
  60. implemented yet. When you start Ghemical it is most useful
  61. doing this out of a terminal because it is still necessary to
  62. make some in- and output on the terminal. But this feature
  63. shall disappear with the version 1.0. Working with the
  64. program the menu panel and the popup menu are the most
  65. important aids. The menu panel owns three items: <i>File</i>,
  66. <i>Windows</i> and <i>Help</i>. It's important to mention now
  67. the program isn't really translated to German. There are only
  68. scattered terms, words and descriptions in German. In the
  69. menu item <i>File</i> you can open projects, load already
  70. existing ones and exit the program. At <i>Windows</i> it is
  71. possible to choose between the following three MDI modes:
  72. <i>Notebook</i>, <i>Toplevel</i> and <i>Modal</i>. And
  73. finally in the last item <i>Help</i> you find either general
  74. information about Ghemical or a link to the
  75. documentation.</p>

  80. <h5>Screenshot 1: Ghemical with aspirin</h5>
  81. <br />
  82. <br />
  83. <p>If you decided for a project at the left brink are a lot
  84. of modification possibilities to work with. These differ from
  85. different rotation and translation directions over the
  86. zooming unless the erasing and adding of atoms and bindings
  87. of course. Clicking on the prompt window for the molecules
  88. with the right mouse button a popup menu appears which
  89. contains different items depending on the project. To mention
  90. are for instance the different presentation possibilities.
  91. Proceeding the single atoms can be indexed differently.
  92. Surely it's interesting too that you can plot the molecules
  93. in different ways among others there is a display for 3D
  94. glasses build in. This popup menu contains then too the basic
  95. functions for saving and closing the projects. The choice
  96. between between different elements and bindings is possible
  97. here too. Beneath these simple function there are more
  98. complex ones too. <b>Where the correct adding of hydrogen
  99. atoms every reader still understands menu item as
  100. "ESP-colored vdW-surface" isn't only imcomprehensible for the
  101. author.</b> At this item the interested user and ongoing PhD
  102. will hopefully understand it. Principally there is a huge
  103. number of different engines and algorithms for studying and
  104. changing the molecules. They seem to be quite professional
  105. for me as layman. The possibility of generating DNA molecules
  106. out of an easy "ACGT code" is absolutely noticeable for
  107. me.</p>

  115. <br />
  116. <p>At the end some tips (mainly from the <a
  117. href="">homepage [3]</a>)
  118. that can help you with the daily usage.</p>
  119. <ol>
  120. <li>For the generation of a quantum mechanic model
  121. principally it is more meaningful to generate a molecular
  122. mechanic one first which then you can transform in a
  123. quantum mechanic one.</li>
  124. <li>All menu panel are freely relocatable and placeable
  125. outside of the main window too.</li>
  126. <li>There are a lot of import and export formats available
  127. for molecular mechanic models.</li>
  128. <li>If you are forced using Windows at work then you can
  129. find a <a
  130. href="">detailed
  131. description [10]</a> about the usage of Ghemical under
  132. Windows.</li>
  133. </ol>
  134. And for those who are still wondering at the end of this
  135. short description how you have to pronounce "Ghemical" can
  136. find an answer in the statement of an developer which says
  137. that generally everybody can pronouce it as he or she want
  138. but the "G" comes from "GNU" and/or "GNOME". <br />
  139. <br />
  140. <p>But now continues to the home of Simple End-User
  141. Linux.</p>
  142. <h3>, the education portal of SEUL - Simple
  143. End-User Linux</h3>
  144. <p><a href="">SEUL/edu [4]</a>
  145. subproject of <a href="">SEUL [11]</a>
  146. stands for "Simpel End-User Linux". The goal of SEUL is
  147. making available an as easy as possible GNU/Linux system for
  148. every user. Thereby qualitatively good software shall arise
  149. which preferably will be released under the terms of the <a
  150. href="">GNU GPL [12]</a>.
  151. To manage and assist this the site is hosting a lot of <a
  152. href="">projects [13]</a>
  153. and makes available mailing lists for the coordination of the
  154. work. Main language in this project and on the website too is
  155. English.</p>
  156. The subproject school and education was founded in 1998. Doug
  157. Loss is the leader at the moment and Karl Peña is managing a
  158. lot of stuff on the <a href="">website
  159. [4]</a>. Beneath these two there are a lot of other
  160. freelancers too. In principle SEUL/edu mainly consists of a
  161. mailing list whose access is already described on the
  162. frontpage and you can subscribe right there too. <br />
  163. <br />
  164. <p><img src="./img/seul-edu.en.png"

  167. </p>
  168. <h5>Screenshot 3: The homepage of SEUL/edu</h5>
  169. <br />
  170. <br />
  171. <p>The homepage of the project is devided in seven sections.
  172. They are: <i>Current projects</i>, <i>Existing software</i>,
  173. <i>Case studies</i>, <i>Documentation</i>, <i>Regular
  174. reports</i>, <i>List archive</i> and <i>Links</i>. There is
  175. only one <a href="">project
  176. [14]</a> now under the first item whose goal it is making
  177. available an ISO-Image containing a counterbalanced
  178. collection of education software. But the development stands
  179. still at the beginning and we will see what will happen with
  180. it. However the database with already <a
  181. href="">existing software [15]</a> is
  182. remarkable by all means and I never saw such a big one in the
  183. internet yet. At the moment the database contains 518
  184. software projects arranged by categories believe it or not.
  185. There is a short description for each entry. Additional and
  186. optional information are: version, date, author, homepage,
  187. download URL and the used license of course. Accessorily it
  188. is possible showing only predetermined data as the license or
  189. a the short description. Important for the further growth is
  190. the easy way to enter new software which is accomplished
  191. through a <a
  192. href="">form on
  193. the website [16]</a>. You can search the entries either for a
  194. destined application or a pretermined word. But don't forget
  195. there is not only Free Software in this database. Because the
  196. people of SEUL/edu collected and catalogued already so much
  197. software it would possibly make sense that other projects use
  198. this database too, integrating it in their webpages and
  199. expand it. A translation in other languages would expand the
  200. circle of possible users again.</p>
  201. <p>They who are searching reports about schools using
  202. GNU/Linux and/or Free Software making a find here too.
  203. SEUL/edu offers <a
  204. href="">reports
  205. [17]</a> of more than 50 schools worldwide. There are a few
  206. from Cuenca in Ecuador to Marl in Germany. It is possible to
  207. easy make new entries with a <a
  208. href="">form [18]</a>
  209. on the website. Under <a
  210. href="">documentation [19]</a> you
  211. don't find as much at the moment. There is already a
  212. classification for the documenation in the future which
  213. contains sections as the <i>Users guide</i> or the
  214. <i>Teachers guide</i>. Even a category helping
  215. decision-makers and people who want to persuade schools of
  216. GNU/Linux and/or Free Software is available. But SEUL/edu
  217. lists <a
  218. href="">foreign
  219. documentation[20]</a> in the same structure too. At the
  220. moment there is a helping description for people who want to
  221. write documentation for one of the named categories.</p>
  222. <p>The project itself releases an extensive report about the
  223. situation of GNU/Linux and Free Software in and at schools at
  224. least twice a month. The since the beginning of 2000
  225. published reports are of course archived on the site <a
  226. href="">[21]</a> so that
  227. everyone can read them at any time. Because SEUL/edu mainly
  228. works and communicates over the mailing list they made an
  229. archive of the list available <a
  230. href="">online [22]</a>
  231. too. And finally under the last item you can find an
  232. extensive <a
  233. href="">links
  234. collection [23]</a> to further sites about the theme
  235. "GNU/Linux, Free and Open Software in and at schools".</p>
  236. <p>But now, let's continue with the idea of this month.</p>
  237. <h3>"Word games generated rapidly"</h3>
  238. <p>For the last idea, concedely a little skinny one, I didn't
  239. receive any implementation because of this continues to the
  240. idea of this edition. Because the ideas introduced until now
  241. were always more or less for learning or teaching at the hard
  242. everyday school life I want to present an idea for loosing
  243. today. Riddles, an invention fascinating and entertaining
  244. humankind since billions of years, can prettify school a
  245. little. Even children find pleasure and happiness with
  246. riddles and guessing games. I think about a quite special
  247. kind which seems to be rather simple to implement and program
  248. too. What I mean is a letters huddle containing different,
  249. mostly thematically coherent words. The task is to search and
  250. find these words in the mix-up. Mostly the letters are
  251. disposed in an rectangle in which the to finding words are
  252. placed horizontally, vertically or diagonally. Thereby the
  253. searching words can be written forward or backward.</p>
  254. <p>Perhaps there is already a piece of software generating
  255. such riddles. And if not such a thing would be implementable
  256. in short time, isn't it ? A little bash script putting words
  257. of a definite category into a letters huddle. Writing this
  258. letters sequence with some <a
  259. href="">(La)TeX [24]</a> commands
  260. into a text file and translating it would result in a quite
  261. good-looking riddle for pupils her excercices already
  262. finished. And the best, if you select correlatively the word
  263. collection pupils even learn the correct orthography or
  264. understand the context between the single word families.
  265. Anyway I'm curious about the ideas you will create. Farther
  266. ideas were for instance that words are written correctly and
  267. wrong in the letters mix-up or you make the whole thing with
  268. numbers.</p>
  269. <p>Once again at this place the calling to send <a
  270. href="">me [1]</a> ideas which you think
  271. are easy to implement or you didn't find comparable software
  272. yet, then I will report about them at this place in one of
  273. the next editions. And perhaps there are firms, schools or
  274. single persons offer a reward for an implementation.</p>
  275. <p>But now continues to a new section.</p>
  276. <h3>News and up to date program versions</h3>
  277. <p>In the future I will report in this section about news of
  278. GNU/Linux and Free Software at school. Beneath I will list
  279. actual program versions of free education software for the
  280. moment only of the programs I already reported about in
  281. TUX&amp;GNU@school. Software whose version changed since the
  282. last edition will be highlighted in red.</p>
  283. <h4>DebianEdu:</h4>
  284. <p>On 6th of september Raphael Hertzog announced the birth of
  285. DebianEDU a subproject of <a
  286. href="">Debian [8]</a>. Interim goal of
  287. the project is it making Debian the best available
  288. distribution school purposes. At the moment they impetuously
  289. dicuss on the <a
  290. href="">mailing
  291. list [25]</a> how they want to go on the first tasks and what
  292. has priority. You can find more information under <a
  293. href="">[26]</a>.</p>
