</a>
34 <p>Recently I have spent some time evaluating the multimedia browser
35 plugins available in Debian Lenny, to see which one we should use by
36 default in Debian Edu. We need an embedded video playing plugin with
37 control buttons to pause or stop the video, and capable of streaming
38 all the multimedia content available on the web. The test results and
39 notes are available on
40 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia">the
41 Debian wiki
</a>. I was surprised how few of the plugins are able to
42 fill this need. My personal video player favorite, VLC, has a really
43 bad plugin which fail on a lot of the test pages. A lot of the MIME
44 types I would expect to work with any free software player (like
45 video/ogg), just do not work. And simple formats like the
46 audio/x-mplegurl format (m3u playlists), just isn't supported by the
47 totem and vlc plugins. I hope the situation will improve soon. No
48 wonder sites use the proprietary Adobe flash to play video.
</p>
50 <p>For Lenny, we seem to end up with the mplayer plugin. It seem to
51 be the only one fitting our needs. :/

74 <p>As part of the work we do in
<a href=
"http://www.nuug.no">NUUG
</a>
75 to publish video recordings of our monthly presentations, we provide a
76 page with embedded video for easy access to the recording. Putting a
77 good set of HTML tags together to get working embedded video in all
78 browsers and across all operating systems is not easy. I hope this
79 will become easier when the
<video
> tag is implemented in all
80 browsers, but I am not sure. We provide the recordings in several
81 formats, MPEG1, Ogg Theora, H
.264 and Quicktime, and want the
82 browser/media plugin to pick one it support and use it to play the
83 recording, using whatever embed mechanism the browser understand.
84 There is at least four different tags to use for this, the new HTML5
85 <video
> tag, the
<object
> tag, the
<embed
> tag and
86 the
<applet
> tag. All of these take a lot of options, and
87 finding the best options is a major challenge.
</p>
89 <p>I just tested the experimental Opera browser available from
<a
90 href=
"http://labs.opera.com">labs.opera.com
</a>, to see how it handled
91 a
<video
> tag with a few video sources and no extra attributes.
92 I was not very impressed. The browser start by fetching a picture
93 from the video stream. Not sure if it is the first frame, but it is
94 definitely very early in the recording. So far, so good. Next,
95 instead of streaming the
76 MiB video file, it start to download all
96 of it, but do not start to play the video. This mean I have to wait
97 for several minutes for the downloading to finish. When the download
98 is done, the playing of the video do not start! Waiting for the
99 download, but I do not get to see the video? Some testing later, I
100 discover that I have to add the
controls="true" attribute to be able
101 to get a play button to pres to start the video. Adding
102 autoplay="true" did not help. I sure hope this is a misfeature of the
103 test version of Opera, and that future implementations of the
104 <video
> tag will stream recordings by default, or at least start
105 playing when the download is done.
</p>
107 <p>The test page I used (since changed to add more attributes) is
108 <a href=
"http://www.nuug.no/aktiviteter/20090113-foredrag-om-foredrag/">available
109 from the nuug site
</a>. Will have to test it with the new Firefox
112 <p>In the test process, I discovered a missing feature. I was unable
113 to find a way to get the URL of the playing video out of Opera, so I
114 am not quite sure it picked the Ogg Theora version of the video. I
115 sure hope it was using the announced Ogg Theora support. :)

</a>
138 <p>Jeg hadde glede av å overvære FADs lansering av
139 <a href=
"http://www.deltemeninger.no/">Debattsentralen
140 deltemeninger.no
</a> under Go Open
2009, og må si jeg ble skuffet over
141 en kommentar fra podiet om ulovlig fildeling. Fikk ikke med meg hvem
142 som holdt innlegget, men det startet med å snakke om ulovlig fildeling
143 og gikk så over til å snakke om fildeling som om fildeling i seg er
144 ulovlig. Intet er lengre fra sannheten. Fildeling er en nyttig
145 teknologi som benyttes av NRK, Debian, Ubuntu, NUUG og andre for
146 distribusjon av filer. Det er ingenting med denne fildelingen som
147 gjør den ulovlig. Fildeling er i seg selv en fullt ut lovlig
148 teknologisk anvendelse. Noe fildeling er ulovlig, og noe er lovlig.
149 De som tror at fildeling er ulovlig har misforstått grovt. Hvorvidt
150 den er ulovlig kommer jo an på hvem som har opphavsretten til filene
151 som deles og hvilke bruksbegrensninger som gjelder for filene. En
152 rekke filer er lagt ut av rettighetsinnehaver for deling på Internet,
153 og fildeling av slike filer er fullt ut lovlig.

</a> som gjør at eldre bøker kan gjøres
180 digitalt tilgjengelig fra nasjonalbiblioteket mot at Kopinor får
56
181 øre for hver side som legges ut. Utvalget er litt merkelig:
1790-,
182 1890- og
1990-tallet. Jeg synes det er absurd hvis det er slik at
183 Kopinor skal ha betalt for utlegging av bøker som ikke lenger er
184 beskyttet av opphavsretten. Jeg antar her at det er mer enn
90 år
185 siden forfatterne av bøker som ble publisert
1790-
1799 døde, slik at
186 disse bøkene er falt i det fri og enhver kan kopiere så mye de vil fra
187 dem uten å bryte opphavsrettsloven. Bruk av slike verk har ikke
188 Kopinor noe med å gjøre. Jeg håper jeg har misforstått.

</p>
193 <p>Et annet problem er at bøkene kun legges ut som bildefiler, noe som
194 vil gjøre at søketjenester ikke vil finne disse bøkene når en søker
195 etter fragmenter i teksten. En risikerer dermed at de blir liggende
196 på en slik måte at folk som bruker Google ikke finner dem.
</p>
198 <p>Da skulle jeg heller sett at nasjonalbiblioteket gjorde alvor av
199 sin aprilspøk, og la ut bøkene som faller i det fri

</a>
224 <p>Just for fun, I did a search right now on Google for a few file ODF
225 and MS Office based formats (not to be mistaken for ISO or ECMA
226 OOXML), to get an idea of their relative usage. I searched using
227 'filetype:odt' and equvalent terms, and got these results:
</P>
230 <tr><th>Type
</th><th>ODF
</th><th>MS Office
</th></tr>
231 <tr><td>Tekst
</td> <td>odt:
282000</td> <td>docx:
308000</td></tr>
232 <tr><td>Presentasjon
</td> <td>odp:
75600</td> <td>pptx:
183000</td></tr>
233 <tr><td>Regneark
</td> <td>ods:
26500 </td> <td>xlsx:
145000</td></tr>
236 <p>Next, I added a 'site:no' limit to get the numbers for Norway, and
237 got these numbers:
</p>
240 <tr><th>Type
</th><th>ODF
</th><th>MS Office
</th></tr>
241 <tr><td>Tekst

2480 </td> <td>docx:

242 <tr><td>Presentasjon

299 </td> <td>pptx:
741</td></tr>
243 <tr><td>Regneark
</td> <td>ods:
187 </td> <td>xlsx:
372</td></tr>
246 <p>I wonder how these numbers change over time.
</p>
248 <p>I am aware of Google returning different results and numbers based
249 on where the search is done, so I guess these numbers will differ if
250 they are conduced in another country. Because of this, I did the same
251 search from a machine in California, USA, a few minutes after the
252 search done from a machine here in Norway.
</p>
256 <tr><th>Type

257 <tr><td>Tekst

258 <tr><td>Presentasjon

93900</td></tr>
259 <tr><td>Regneark
</td> <td>ods:
26500 </td> <td>xlsx:
82400</td></tr>
262 <p>And with 'site:no':
265 <tr><th>Type

</th></tr>
266 <tr><td>Tekst
</td> <td>odt:
2480</td> <td>docx:

268 <tr><td>Regneark

271 <p>Interesting difference, not sure what to conclude from these

295 <p>The last few weeks i have had the pleasure of reading a
296 thought-provoking collection of essays by Cory Doctorow, on topics
297 touching copyright, virtual worlds, the future of man when the

299 book titled "Content: Selected Essays on Technology, Creativity,

333 <a href=
"http://nroets.dev.openstreetmap.org/demo/index.html?layers=B000FTFTT">support
334 for calculating routes
</a>. The support is still experimental and
335 only available from the development server, until more experience is
336 gathered on the user interface and any scalability issues.
</p>
338 <p>Earlier, the routing I knew about using the OpenStreetmap.org data
339 was provided by
<a href=
"http://maps.cloudmade.com/">Cloudmade
</a>,
340 but having it on the main page is required to make everyone aware of
341 the issue. I've had people reject Openstreetmap.org as a viable
342 alternative for them because the front page lacked routing support,
343 and I hope their needs will be catered for when routing show up on the
344 www.openstreetmap.org front page.

367 <p>In the
<a href=

</a>, the adobe-flashplugin package the
369 second most popular used package that is missing in Debian. The sixth
370 most popular is flashplayer-mozilla. This is a clear indication that
371 working flash is important for Debian users. Around
10 percent of the
372 users submitting data to popcon.debian.org have this package
375 <p>In the report written by Lars Risan in August
2008
376 («
<a href=
"http://wiki.skolelinux.no/Dokumentasjon/Rapporter?action=AttachFile&do=view&target=Skolelinux_i_bruk_rapport_1.0.pdf">Skolelinux
377 i bruk – Rapport for Hurum kommune, Universitetet i Agder og
378 stiftelsen SLX Debian Labs
</a>»), one of the most important problems
379 schools experienced with
<a href=
"http://www.skolelinux.org/">Debian
380 Edu/Skolelinux
</a> was the lack of working Flash. A lot of educational
381 web sites require Flash to work, and lacking working Flash support in
382 the web browser and the problems with installing it was perceived as a
383 good reason to stay with Windows.
</p>
385 <p>I once saw a funny and sad comment in a web forum, where Linux was
386 said to be the retarded cousin that did not really understand
387 everything you told him but could work fairly well. This was a
388 comment regarding the problems Linux have with proprietary formats and
389 non-standard web pages, and is sad because it exposes a fairly common
390 understanding of whose fault it is if web pages that only work in for
391 example Internet Explorer
6 fail to work on Firefox, and funny because
392 it explain very well how annoying it is for users when Linux
393 distributions do not work with the documents they receive or the web
394 pages they want to visit.
</p>
396 <p>This is part of the reason why I believe it is important for Debian
397 and Debian Edu to have a well working Flash implementation in the
398 distribution, to get at least popular sites as Youtube and Google
399 Video to working out of the box. For Squeeze, Debian have the chance
400 to include the latest version of Gnash that will make this happen, as
401 the new release
0.8.8 was published a few weeks ago and is resting in
402 unstable. The new version work with more sites that version
0.8.7.
403 The Gnash maintainers have asked for a freeze exception, but the
404 release team have not had time to reply to it yet. I hope they agree
405 with me that Flash is important for the Debian desktop users, and thus
406 accept the new package into Squeeze.

429 <p>A few days ago I had the mixed pleasure of bying a new digital
430 camera, a Canon IXUS
130. It was instructive and very disturbing to
431 be able to verify that also this camera producer have the nerve to
432 specify how I can or can not use the videos produced with the camera.
433 Even thought I was aware of the issue, the options with new cameras
434 are limited and I ended up bying the camera anyway. What is the
435 problem, you might ask? It is software patents, MPEG-
4, H
.264 and the
436 MPEG-LA that is the problem, and our right to record our experiences
437 without asking for permissions that is at risk.
439 <p>On page
27 of the Danish instruction manual, this section is

449 <p>No license is granted or implied for any other use for MPEG-

453 <p>In short, the camera producer have chosen to use technology
454 (MPEG-

455 non-commercial purposes, or ask for permission from the organisations
456 holding the knowledge monopoly (patent) for technology used.
