  8. <h1>TUX&amp;GNU@school - 3rd edition</h1>
  9. <p><i>Every month the column <a
  10. href="http://www.fsfeurope.org/activities/education/tgs/tgs.en.html">TUX&amp;GNU@school
  11. [2]</a> reports about free education software, a homepage on
  12. the topic and an easy to implement idea. This month I talk
  13. about <a href="http://edu.kde.org/kgeo">KGeo</a>, a free
  14. geometry programm for KDE, about <a
  15. href="http://www.edux.ch">edux.ch</a>, the info portal for
  16. Swiss schools and GNU/Linux and about the idea "Textfilter -
  17. filters once for a good thing".</i></p>
  18. <p>Welcome to the third and last edition of
  19. TUX&amp;GNU@school, the "last" only in the sense of the first
  20. triple serie ending with this edition. Now it's definitive: I
  21. will release the column furthermore monthly. With the next
  22. edition there are some news but more about this in the next
  23. month. But now to the first item.</p>
  24. <h3>KGeo - Geometry with the mouse</h3>
  25. <p>KGeo <a href="http://edu.kde.org/kgeo">[3]</a> <a
  26. href="http://kgeo.sourceforge.net">[4]</a> is a free geometry
  27. education program which which recently became part of the <a
  28. href="http://edu.kde.org">KDE-Edutainment project [5]</a>.
  29. It's developed by Marc Bratsch and available in German and
  30. English at the moment. I tested the Version 1.0.2 under
  31. Debian GNU/Linux 3.0 and KDE 2.2.2.</p>
  32. <p>After the first start you right catch sight of the main
  33. window of KGeo in which the single function panels are
  34. disposed at the sides. The construction board with an
  35. underlying coordinate system is in the middle. Generally the
  36. interfaces isn't overloaded with functions and with it
  37. clearly. Besides the menu the program has another five
  38. function panels until now that each user can arrange him- or
  39. herself. Thereby three panels are thought for the
  40. construction of geometric objects, another one contains
  41. functions for measuring and calculating of lengths, areas,
  42. etc. and the last panel invokes general ways you need for
  43. erasing or moving of objects.</p>
  44. <p>When the user works with KGeo, he is always in one of
  45. three modes. These are the construction mode, the drag mode
  46. and trace mode. It is possible, in the construction mode, to
  47. draw geometric objects like points, routes or triangles
  48. farther there are methods for vectors, centres, parallels or
  49. angles too. With combination of these objects and methods you
  50. then even can construct reflections, translations or
  51. rotations. If you want to size the drawn figures the
  52. developer made tools to measure the circle areas, distances,
  53. angles, slopes or circumfences. All construction buttons have
  54. an information window that appears if the mouse pointer is
  55. over the button. These windows and the short sentence in the
  56. status panel explain the function as good that you don't have
  57. to work in and you can begin your work in a moment.</p>
  58. <p><img src="./img/kgeo.en.png"

  61. </p>
  62. <h5>Screenshot 1: KGeo and the theorem of Thales</h5>
  63. <br />
  64. <br />
  65. <p>In the drag mode you can move the single objects in the
  66. coordinate system, dependences like reflection or a rotations
  67. with certain angle stay maintained respectively are ongoing
  68. tracked. By enabling the trace mode too which is possible for
  69. each point separately, you can even track the exact move or
  70. points. Then if you're happy with your drawing and you want
  71. not only save it but also showing the result to your teacher
  72. the next day, the best way to do this is to print it. Of
  73. course this can KGeo too.</p>
  74. <p>But for all that there is of course a German and English
  75. manual for the ongoing geometry masteress. That is quite
  76. short and bare but even so good and easy to understand. I
  77. personally like especially the chapter "Using KGeo" which
  78. explains constructions for the encouragement at schools but
  79. "only" the theorem of the Thales circle up to now. But I'm
  80. sure some of the TUX&amp;GNU@school readers could change this
  81. ?!? If in any case we talk about KGeo at school I want to
  82. talk about the possibility switching KGeo into the Kioskmode.
  83. In this mode the coordinate system with the drawing is
  84. displayed on the whole screen but you can't change anything
  85. then. But at the end of the report I have to give you some
  86. bad news. It seems as if KGeo isn't developed anymore at
  87. least at the moment. Nevertheless a large "thank you" to Marc
  88. for the program, I like it and surely not only me.</p>
  89. <p>But now continues to the home of the "ALIS - Arbeitsgruppe
  90. Linux an Schulen" (Swiss work group for linux at school).</p>
  91. <h3>edux.ch - the info portal for Swiss schools and
  92. GNU/Linux</h3>
  93. <p>At least, a <a href="http://www.edux.ch">project [6]</a>
  94. which I am actively working in, and, besides that, the
  95. project out of which the TUX&amp;GNU@school originated. The
  96. "ALIS - Arbeitsgruppe Linux an Schulen" (Swiss work group for
  97. linux at school), the group behind edux.ch, originated out of
  98. the <a href="http://www.lugs.ch">LUGS - Linux User Group
  99. Switzerland [7]</a> in november 2001. The three people
  100. Christoph Kuhn, Daniel Dahinden and Mario Fux founded the
  101. task force all people employing with Free Software and
  102. GNU/Linux at schools already beforehand. We want to create an
  103. information plattform for all the Swiss (and other) schools
  104. interesting on the topic.</p>
  105. <p>When you enter the URL <a
  106. href="http://www.edux.ch">http://www.edux.ch</a> in the
  107. favorite browser, first you'll see a welcome page. Following
  108. the shown link you'll come to the front page of the Swiss
  109. information portal. This is divided in three columns as you
  110. can see in screenshot 2. Leftmost there is the navigation
  111. panel which is on all the other sides too, beneath it an
  112. input window for the username and the password is situated
  113. where interested and already registered people can log in. At
  114. the right side there are some links to chummy groups and
  115. projects like the already known <a
  116. href="http://www.pingos.schulnetz.org">PingoS [8]</a> or <a
  117. href="http://www.wilhelmtux.ch">WilhelmTUX [9]</a>. As you
  118. can see at the navigation panel the website ist subdivided in
  119. seven sections up to now. Thereby the first is the front page
  120. itself whereas all the rest have subsections unless <a
  121. href="http://www.edux.ch/nav.php?site=26">"Kontakt" (contact)
  122. [10]</a>.</p>
  123. <p><img src="./img/edux.en.png"
  124. alt="Screenshot 2: Front page of edux.ch" width="800"
  125. height="600" border="0" /><br />
  126. Screenshot 2: Front page of edux.ch</p>
  127. <p>In the first purview <a
  128. href="http://www.edux.ch/nav.php?site=29">"Alles über ALIS"
  129. (everything about ALIS) [11]</a> the interested reader can
  130. get to know more about the task force e.g. how the group is
  131. compound and how it is originated. By now the third <a
  132. href="http://www.edux.ch/nav.php?site=81">link [12]</a>
  133. should show you something well known viz the current and all
  134. past editions of TUX&amp;GNU@school. Probably in the near
  135. future there you can find more about the "easy to implement
  136. ideas" mainly about the already implemented ones. In the
  137. section <a
  138. href="http://www.edux.ch/nav.php?site=47">"Education
  139. Software" [13]</a> you can find information about <a
  140. href="http://www.lernnetz-sh.de/kmlinux">kmLinux [14]</a> and
  141. you can order it in Switzerland. More about kmLinux perhaps
  142. more in one of the next editions. You can find there a <a
  143. href="http://www.edux.ch/nav.php?site=68">"Linksammlung"
  144. (link collection) [15]</a> about free education software and
  145. conditional sites.</p>
  146. <p>Then the fifth reference guides to a central section of
  147. edux.ch, the <a
  148. href="http://www.edux.ch/forum/index.php?f=0">Forum [16]</a>.
  149. So far three active forums and a test-forum are arranged. You
  150. can discuss and criticise about themes in the context of Free
  151. Software at schools in the forums "Linux im Bildungsbereich"
  152. (Linux at school), "Fragen zu Linux-Software" (questions
  153. about linux software) and "Anregungen und Kritik an ALIS"
  154. (suggestions and criticism about ALIS). The first two forums
  155. can be subscribed optionally as mailing lists too.</p>
  156. <p>You find <a
  157. href="http://www.edux.ch/nav.php?site=64">brochures [17]</a>
  158. in the second last section. There will be more in the future
  159. but until now you'll find a linux guide called "SuSE Linux
  160. verwenden - Ein Leitfaden für Windows- und
  161. Macintosh-BenutzerInnen" (Using SuSE Linux - a guide für
  162. users of Windows and MacOS), a selection of German
  163. OpenOffice.org and StarOffice courses for downloading as pdf
  164. or text files and a German and French documentation about the
  165. free 2D-CAD software <a href="http://www.qcad.org">QCad
  166. [18]</a>. How and where you can find us is written on the
  167. last page under <a
  168. href="http://www.edux.ch/nav.php?site=26">"Kontakt" (contact)
  169. [10]</a>.</p>
  170. <p>What we're still missing is more (wo)manpower. We have
  171. many ideas and a lot to do and need additional helpers for
  172. that. If somebody is interested he or she can send us an
  173. email to <a href="mailto:alis@lugs.ch">[19]</a>. As a little
  174. stimulus I still want to mention two projects we're working
  175. on: On the one hand this is the email survey on education
  176. software publishers concerning available education software
  177. for GNU/Linux and on the other hand we test education
  178. software for Windows and Macintosh under <a
  179. href="http://www.winehq.com">WINE [20]</a> and <a
  180. href="http://www.transgaming.com">WineX [21]</a> and then we
  181. write little HOWTOs.</p>
  182. <p>Oh yes before I'll forget it. For all the people who
  183. doesn't know it, Switzerland has got four national languages
  184. and so you always have to accost all speech groups. We want
  185. this too and as a first step we'll publish our whole website
  186. besides in German in French too. Interesting translators for
  187. Italian and Rätoromanic are supposed to send an email to <a
  188. href="mailto:alis@lugs.ch">[19]</a>.</p>
  189. <h3>"Textfilter - filters once for a good thing"</h3>
  190. <p>Before I'll come to the idea of this month I can talk this
  191. time too about an implementation of idea of the last month.
  192. For remembrance: The idea of the last time was to format
  193. text, to use small and large letters and to erase punctuation
  194. marks. Already one week after publishing <a
  195. href="http://www.fsfeurope.org/activities/education/tgs/tagatschool2.en.html">TUX&amp;GNU@school
  196. 2 [22]</a> Roland Spielhofer told me that he implemented the
  197. idea in PHP and that it is now available unter <a
  198. href="http://zbp.boku.ac.at/schule/">[23]</a>. After a query
  199. about the source code he told me among others that the
  200. conversion took "only" half an hour. This is a good example
  201. for what I want to accomplish with this section. A problem
  202. that tooks a lot of time for a teacher or a pupil can be
  203. implemented by a talented programmer in only a few minutes
  204. and so saving time for a lot of people. Nevertheless or right
  205. therefore the work of the programmer should be appreciated.
  206. Also a "thank you" to Roland in Vienna, Austria for this
  207. time.</p>
  208. <p><img src="./img/text4mator.en.png"
  209. alt="Screenshot 3: Text4mator from Vienna" width="800"
  210. height="600" border="0" /><br />
  211. </p>
  212. <h5>Screenshot 3: Text4mator form Vienna</h5>
  213. <br />
  214. <br />
  215. <p>But now to the idea of this month. Who doesn't know the
  216. separation excercises we all made at school. Well already
  217. various worksheets were made for this theme and will made
  218. again. Thereby and by related jobs the elaborating teachers
  219. have alwasy to make lists with complying words. For the
  220. hacker next door it would be easy to write a program or
  221. script which searches words out of a text, given or searched
  222. in the internet, and packetises in a list. Perhaps even
  223. making a worksheet yet ?!? I concede this month's idea isn't
  224. far thought respectively worked out. But let you flow your
  225. neurons and surprise the readers of the next edition with
  226. further going and maybe crazy ideas.</p>
  227. <p>At the end I still want to ask for reports for a new
  228. section in this column. At the next or the next but one time
  229. I want initiate a new section beneath the existing three
  230. reporting about already realised projects at schools and
  231. migration to free software and/or GNU/Linux. If you don't
  232. want to write your own report you can answer to the questions
  233. next released under <a
  234. href="http://www.edux.ch/nav.php?site=81">[12]</a> and send
  235. the text to <a href="mailto:foxman@lugo.ch">me</a>.</p>
  236. <p>That's it for this month. Up to the next time when there
  237. are a lot of news ;-).</p>
