  24       <div class="date"> 9th August 2015</div>
  25       <div class="body"><p>Typesetting a book is harder than I hoped.  As the translation is
  26 mostly done, and a volunteer proof reader was going to check the text
  27 on paper, it was time this summer to focus on formatting my translated
  28 <a href="http://www.docbook.org/">docbook</a> based version of the
  29 <a href="http://free-culture.cc/">Free Culture</a> book by Lawrence
  30 Lessig.  I've been trying to get both docboox-xsl+fop and dblatex to
  31 give me a good looking PDF, but in the end I went with dblatex, because
  32 its Debian maintainer and upstream developer were responsive and very
  33 helpful in solving my formatting challenges.</p>
  34
  35 <p>Last night, I finally managed to create a PDF that no longer made
  36 <a href="http://www.lulu.com/">Lulu.com</a> complain after uploading,
  37 and I ordered a text version of the book on paper.  It is lacking a
  38 proper book cover and is not tagged with the correct ISBN number, but
  39 should give me an idea what the finished book will look like.</p>
  40
  41 <p>Instead of using Lulu, I did consider printing the book using
  42 <a href="http://www.createspace.com/">CreateSpace</a>, but ended up
  43 using Lulu because it had smaller book size options (CreateSpace seem
  44 to lack pocket book with extended distribution).  I looked for a
  45 similar service in Norway, but have not seen anything so far.  Please
  46 let me know if I am missing out on something here.</p>
  47
  48 <p>But I still struggle to decide the book size.  Should I go for
  49 pocket book (4.25x6.875 inches / 10.8x17.5 cm) with 556 pages, Digest
  50 (5.5x8.5 inches / 14x21.6 cm) with 323 pages or US Trade (6x8 inches /
  51 15.3x22.9 cm) with 280 pages?  Fewer pager give a cheaper book, and a
  52 smaller book is easier to carry around.  The test book I ordered was
  53 pocket book sized, to give me an idea how well that fit in my hand,
  54 but I suspect I will end up using a digest sized book in the end to
  55 bring the prize down further.</p>
  56
  57 <p>My biggest challenge at the moment is making nice cover art.  My
  58 inkscape skills are not yet up to the task of replicating the original
  59 cover in SVG format.  I also need to figure out what to write about
  60 the book on the back (will most likely use the same text as the
  61 description on web based book stores).  I would love help with this,
  62 if you are willing to license the art source and final version using
  63 the same CC license as the book.  My artistic skills are not really up
  64 to the task.</p>
  65
  66 <p>I plan to publish the book in both English and Norwegian and on
  67 paper, in PDF form as well as EPUB and MOBI format.  The current
  68 status can as usual be found on
  69 <a href="https://github.com/petterreinholdtsen/free-culture-lessig">github</a>
  70 in the archive/ directory.  So far I have spent all time on making the
  71 PDF version look good.  Someone should probably do the same with the
  72 dbtoepub generated e-book.  Help is definitely needed here, as I
  73 expect to run out of steem before I find time to improve the epub
  74 formatting.</p>
  75
  76 <p>Please let me know via github if you find typos in the book or
  77 discover translations that should be improved.  The final proof
  78 reading is being done right now, and I expect to publish the finished
  79 result in a few months.</p>

  93       <div class="date">16th July 2015</div>
  94       <div class="body"><p>I'm still working on the Norwegian version of the
  95 <a href="http://free-culture.cc/">Free Culture book by Lawrence
  96 Lessig</a>, and is now working on the final typesetting and layout.
  97 One of the features I want to get the structure similar to the
  98 original book is to typeset the footnotes as endnotes in the notes
  99 chapter.  Based on the
 100 <a href="https://bugs.debian.org/685063">feedback from the Debian
 101 maintainer and the dblatex developer</a>, I came up with this recipe I
 102 would like to share with you.  The proposal was to create a new LaTeX
 103 class file and add the LaTeX code there, but this is not always
 104 practical, when I want to be able to replace the class using a make
 105 file variable.  So my proposal misuses the latex.begindocument XSL
 106 parameter value, to get a small fragment into the correct location in
 107 the generated LaTeX File.</p>
 108
 109 <p>First, decide where in the DocBook document to place the endnotes,
 110 and add this text there:</p>
 111
 112 <pre>
 113 &lt;?latex \theendnotes ?&gt;
 114 </pre>
 115
 116 <p>Next, create a xsl stylesheet file dblatex-endnotes.xsl to add the
 117 code needed to add the endnote instructions in the preamble of the
 118 generated LaTeX document, with content like this:</p>
 119
 120 <pre>
 121 &lt;?xml version='1.0'?&gt;
 122 &lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'&gt;
 123   &lt;xsl:param name="latex.begindocument"&gt;
 124     &lt;xsl:text&gt;
 125 \usepackage{endnotes}
 126 \let\footnote=\endnote
 127 \def\enoteheading{\mbox{}\par\vskip-\baselineskip }
 128 \begin{document}
 129     &lt;/xsl:text&gt;
 130   &lt;/xsl:param&gt;
 131 &lt;/xsl:stylesheet&gt;
 132 </pre>
 133
 134 <p>Finally, load this xsl file when running dblatex, for example like
 135 this:</p>
 136
 137 <pre>
 138 dblatex --xsl-user=dblatex-endnotes.xsl freeculture.nb.xml
 139 </pre>
 140
 141 <p>The end result can be seen on github, where
 142 <a href="https://github.com/petterreinholdtsen/free-culture-lessig">my
 143 book project</a> is located.</p>

 158       <div class="body"><p>I går fikk vi endelig lansert en norsk version av mySocietys
 159 <a href="https://www.whatdotheyknow.com/">WhatDoTheyKnow</a>.
 160 Tjenesten heter Mimes brønn, og ble
 161 <a href="http://www.nuug.no/news/NUUG_lanserer_innsynstjenesten_Mimes_Br_nn.shtml">annonsert
 162 av NUUG</a> via blogg, epost og twitter til NUUG-assosierte personer.
 163 Det har tatt noen år, men de siste dagene fikk vi endelig tid til å få
 164 på plass de siste bitene.  Vi er to, Gorm og meg selv, som har vært
 165 primus motor for det hele, men vi har fått hjelp med oversettelser og
 166 oppsett fra mange flere.  Jeg vil si tusen takk til hver og en av dem,
 167 og er veldig fornøyd med at vi klarte å få tjenesten opp å kjøre før
 168 ferietiden slo inn for fullt.</p>
 169
 170 <p>Vi er usikker på hvor mye belastning den virtuelle maskinen der
 171 tjenesten kjører klarer, så vi har lansert litt i det stille og ikke
 172 til for mange folk for å se hvordan maskinen klarer seg over sommeren,
 173 før vi går mer aktivt ut og annonserer til høsten.  Ta en titt, og se
 174 om du kanskje har et spørsmål til det offentlige som er egnet å sende
 175 inn via Mimes brønn.</p>
 176
 177 <p>Hvis du lurer på hva i alle dager en slik tjenestes kan brukes til,
 178 anbefaler jeg deg å se
 179 <a href="http://beta.frikanalen.no/video/625321">TED-foredraget til
 180 Heather Brook</a> om hvordan hun brukte WhatDoTheyKnow til å lære
 181 hvordan offentlige midler ble misbrukt.  Det er en inspirerende
 182 historie.</p>

 196       <div class="date"> 7th July 2015</div>
 197       <div class="body"><p>After asking the Norwegian Broadcasting Company (NRK)
 198 <a href="http://people.skolelinux.org/pere/blog/Hva_gj_r_at_NRK_kan_distribuere_H_264_video_uten_patentavtale_med_MPEG_LA_.html">why
 199 they can broadcast and stream H.264 video without an agreement with
 200 the MPEG LA</a>, I was wiser, but still confused.  So I asked MPEG LA
 201 if their understanding matched that of NRK.  As far as I can tell, it
 202 does not.</p>
 203
 204 <p>I started by asking for more information about the various
 205 licensing classes and what exactly is covered by the "Internet
 206 Broadcast AVC Video" class that NRK pointed me at to explain why NRK
 207 did not need a license for streaming H.264 video:
 208
 209 <p><blockquote>
 210
 211 <p>According to
 212 <a href="http://www.mpegla.com/Lists/MPEG%20LA%20News%20List/Attachments/226/n-10-02-02.pdf">a
 213 MPEG LA press release dated 2010-02-02</a>, there is no charge when
 214 using MPEG AVC/H.264 according to the terms of "Internet Broadcast AVC
 215 Video".  I am trying to understand exactly what the terms of "Internet
 216 Broadcast AVC Video" is, and wondered if you could help me.  What
 217 exactly is covered by these terms, and what is not?</p>
 218
 219 <p>The only source of more information I have been able to find is a
 220 PDF named
 221 <a href="http://www.mpegla.com/main/programs/avc/Documents/avcweb.pdf">AVC
 222 Patent Portfolio License Briefing</a>, which states this about the
 223 fees:</p>
 224
 225 <ul>
 226  <li>Where End User pays for AVC Video
 227   <ul>
 228    <li>Subscription (not limited by title) – 100,000 or fewer
 229      subscribers/yr = no royalty; &gt; 100,000 to 250,000 subscribers/yr =
 230      $25,000; &gt;250,000 to 500,000 subscribers/yr = $50,000; &gt;500,000 to
 231      1M subscribers/yr = $75,000; &gt;1M subscribers/yr = $100,000</li>
 232
 233    <li>Title-by-Title - 12 minutes or less = no royalty; &gt;12 minutes in
 234      length = lower of (a) 2% or (b) $0.02 per title</li>
 235   </ul></li>
 236
 237  <li>Where remuneration is from other sources
 238   <ul>
 239    <li>Free Television - (a) one-time $2,500 per transmission encoder or
 240      (b) annual fee starting at $2,500 for &gt; 100,000 HH rising to
 241      maximum $10,000 for &gt;1,000,000 HH</li>
 242
 243    <li>Internet Broadcast AVC Video (not title-by-title, not subscription)
 244      – no royalty for life of the AVC Patent Portfolio License</li>
 245   </ul></li>
 246 </ul>
 247
 248 <p>Am I correct in assuming that the four categories listed is the
 249 categories used when selecting licensing terms, and that "Internet
 250 Broadcast AVC Video" is the category for things that do not fall into
 251 one of the other three categories?  Can you point me to a good source
 252 explaining what is ment by "title-by-title" and "Free Television" in
 253 the license terms for AVC/H.264?</p>
 254
 255 <p>Will a web service providing H.264 encoded video content in a
 256 "video on demand" fashing similar to Youtube and Vimeo, where no
 257 subscription is required and no payment is required from end users to
 258 get access to the videos, fall under the terms of the "Internet
 259 Broadcast AVC Video", ie no royalty for life of the AVC Patent
 260 Portfolio license?  Does it matter if some users are subscribed to get
 261 access to personalized services?</p>
 262
 263 <p>Note, this request and all answers will be published on the
 264 Internet.</p>
 265 </blockquote></p>
 266
 267 <p>The answer came quickly from Benjamin J. Myers, Licensing Associate
 268 with the MPEG LA:</p>
 269
 270 <p><blockquote>
 271 <p>Thank you for your message and for your interest in MPEG LA.  We
 272 appreciate hearing from you and I will be happy to assist you.</p>
 273
 274 <p>As you are aware, MPEG LA offers our AVC Patent Portfolio License
 275 which provides coverage under patents that are essential for use of
 276 the AVC/H.264 Standard (MPEG-4 Part 10).  Specifically, coverage is
 277 provided for end products and video content that make use of AVC/H.264
 278 technology.  Accordingly, the party offering such end products and
 279 video to End Users concludes the AVC License and is responsible for
 280 paying the applicable royalties.</p>
 281
 282 <p>Regarding Internet Broadcast AVC Video, the AVC License generally
 283 defines such content to be video that is distributed to End Users over
 284 the Internet free-of-charge.  Therefore, if a party offers a service
 285 which allows users to upload AVC/H.264 video to its website, and such
 286 AVC Video is delivered to End Users for free, then such video would
 287 receive coverage under the sublicense for Internet Broadcast AVC
 288 Video, which is not subject to any royalties for the life of the AVC
 289 License.  This would also apply in the scenario where a user creates a
 290 free online account in order to receive a customized offering of free
 291 AVC Video content.  In other words, as long as the End User is given
 292 access to or views AVC Video content at no cost to the End User, then
 293 no royalties would be payable under our AVC License.</p>
 294
 295 <p>On the other hand, if End Users pay for access to AVC Video for a
 296 specific period of time (e.g., one month, one year, etc.), then such
 297 video would constitute Subscription AVC Video.  In cases where AVC
 298 Video is delivered to End Users on a pay-per-view basis, then such
 299 content would constitute Title-by-Title AVC Video.  If a party offers
 300 Subscription or Title-by-Title AVC Video to End Users, then they would
 301 be responsible for paying the applicable royalties you noted below.</p>
 302
 303 <p>Finally, in the case where AVC Video is distributed for free
 304 through an "over-the-air, satellite and/or cable transmission", then
 305 such content would constitute Free Television AVC Video and would be
 306 subject to the applicable royalties.</p>
 307
 308 <p>For your reference, I have attached
 309 <a href="http://people.skolelinux.org/pere/blog/images/2015-07-07-mpegla.pdf">a
 310 .pdf copy of the AVC License</a>. You will find the relevant
 311 sublicense information regarding AVC Video in Sections 2.2 through
 312 2.5, and the corresponding royalties in Section 3.1.2 through 3.1.4.
 313 You will also find the definitions of Title-by-Title AVC Video,
 314 Subscription AVC Video, Free Television AVC Video, and Internet
 315 Broadcast AVC Video in Section 1 of the License.  Please note that the
 316 electronic copy is provided for informational purposes only and cannot
 317 be used for execution.</p>
 318
 319 <p>I hope the above information is helpful.  If you have additional
 320 questions or need further assistance with the AVC License, please feel
 321 free to contact me directly.</p>
 322 </blockquote></p>
 323
 324 <p>Having a fresh copy of the license text was useful, and knowing
 325 that the definition of Title-by-Title required payment per title made
 326 me aware that my earlier understanding of that phrase had been wrong.
 327 But I still had a few questions:</p>
 328
 329 <p><blockquote>
 330 <p>I have a small followup question.  Would it be possible for me to get
 331 a license with MPEG LA even if there are no royalties to be paid?  The
 332 reason I ask, is that some video related products have a copyright
 333 clause limiting their use without a license with MPEG LA.  The clauses
 334 typically look similar to this:
 335
 336 <p><blockquote>
 337   This product is licensed under the AVC patent portfolio license for
 338   the personal and non-commercial use of a consumer to (a) encode
 339   video in compliance with the AVC standard ("AVC video") and/or (b)
 340   decode AVC video that was encoded by a consumer engaged in a
 341   personal and non-commercial activity and/or AVC video that was
 342   obtained from a video provider licensed to provide AVC video. No
 343   license is granted or shall be implied for any other use. additional
 344   information may be obtained from MPEG LA L.L.C.
 345 </blockquote></p>
 346
 347 <p>It is unclear to me if this clause mean that I need to enter into
 348 an agreement with MPEG LA to use the product in question, even if
 349 there are no royalties to be paid to MPEG LA.  I suspect it will
 350 differ depending on the jurisdiction, and mine is Norway.  What is
 351 MPEG LAs view on this?</p>
 352 </blockquote></p>
 353
 354 <p>According to the answer, MPEG LA believe those using such tools for
 355 non-personal or commercial use need a license with them:</p>
 356
 357 <p><blockquote>
 358
 359 <p>With regard to the Notice to Customers, I would like to begin by
 360 clarifying that the Notice from Section 7.1 of the AVC License
 361 reads:</p>
 362
 363 <p>THIS PRODUCT IS LICENSED UNDER THE AVC PATENT PORTFOLIO LICENSE FOR
 364 THE PERSONAL USE OF A CONSUMER OR OTHER USES IN WHICH IT DOES NOT
 365 RECEIVE REMUNERATION TO (i) ENCODE VIDEO IN COMPLIANCE WITH THE AVC
 366 STANDARD ("AVC VIDEO") AND/OR (ii) DECODE AVC VIDEO THAT WAS ENCODED
 367 BY A CONSUMER ENGAGED IN A PERSONAL ACTIVITY AND/OR WAS OBTAINED FROM
 368 A VIDEO PROVIDER LICENSED TO PROVIDE AVC VIDEO. NO LICENSE IS GRANTED
 369 OR SHALL BE IMPLIED FOR ANY OTHER USE. ADDITIONAL INFORMATION MAY BE
 370 OBTAINED FROM MPEG LA, L.L.C. SEE HTTP://WWW.MPEGLA.COM</p>
 371
 372 <p>The Notice to Customers is intended to inform End Users of the
 373 personal usage rights (for example, to watch video content) included
 374 with the product they purchased, and to encourage any party using the
 375 product for commercial purposes to contact MPEG LA in order to become
 376 licensed for such use (for example, when they use an AVC Product to
 377 deliver Title-by-Title, Subscription, Free Television or Internet
 378 Broadcast AVC Video to End Users, or to re-Sell a third party's AVC
 379 Product as their own branded AVC Product).</p>
 380
 381 <p>Therefore, if a party is to be licensed for its use of an AVC
 382 Product to Sell AVC Video on a Title-by-Title, Subscription, Free
 383 Television or Internet Broadcast basis, that party would need to
 384 conclude the AVC License, even in the case where no royalties were
 385 payable under the License.  On the other hand, if that party (either a
 386 Consumer or business customer) simply uses an AVC Product for their
 387 own internal purposes and not for the commercial purposes referenced
 388 above, then such use would be included in the royalty paid for the AVC
 389 Products by the licensed supplier.</p>
 390
 391 <p>Finally, I note that our AVC License provides worldwide coverage in
 392 countries that have AVC Patent Portfolio Patents, including
 393 Norway.</p>
 394
 395 <p>I hope this clarification is helpful.  If I may be of any further
 396 assistance, just let me know.</p>
 397 </blockquote></p>
 398
 399 <p>The mentioning of Norwegian patents made me a bit confused, so I
 400 asked for more information:</p>
 401
 402 <p><blockquote>
 403
 404 <p>But one minor question at the end.  If I understand you correctly,
 405 you state in the quote above that there are patents in the AVC Patent
 406 Portfolio that are valid in Norway.  This make me believe I read the
 407 list available from &lt;URL:
 408 <a href="http://www.mpegla.com/main/programs/AVC/Pages/PatentList.aspx">http://www.mpegla.com/main/programs/AVC/Pages/PatentList.aspx</a>
 409 &gt; incorrectly, as I believed the "NO" prefix in front of patents
 410 were Norwegian patents, and the only one I could find under Mitsubishi
 411 Electric Corporation expired in 2012.  Which patents are you referring
 412 to that are relevant for Norway?</p>
 413
 414 </blockquote></p>
 415
 416 <p>Again, the quick answer explained how to read the list of patents
 417 in that list:</p>
 418
 419 <p><blockquote>
 420
 421 <p>Your understanding is correct that the last AVC Patent Portfolio
 422 Patent in Norway expired on 21 October 2012.  Therefore, where AVC
 423 Video is both made and Sold in Norway after that date, then no
 424 royalties would be payable for such AVC Video under the AVC License.
 425 With that said, our AVC License provides historic coverage for AVC
 426 Products and AVC Video that may have been manufactured or Sold before
 427 the last Norwegian AVC patent expired.  I would also like to clarify
 428 that coverage is provided for the country of manufacture and the
 429 country of Sale that has active AVC Patent Portfolio Patents.</p>
 430
 431 <p>Therefore, if a party offers AVC Products or AVC Video for Sale in
 432 a country with active AVC Patent Portfolio Patents (for example,
 433 Sweden, Denmark, Finland, etc.), then that party would still need
 434 coverage under the AVC License even if such products or video are
 435 initially made in a country without active AVC Patent Portfolio
 436 Patents (for example, Norway).  Similarly, a party would need to
 437 conclude the AVC License if they make AVC Products or AVC Video in a
 438 country with active AVC Patent Portfolio Patents, but eventually Sell
 439 such AVC Products or AVC Video in a country without active AVC Patent
 440 Portfolio Patents.</p>
 441 </blockquote></p>
 442
 443 <p>As far as I understand it, MPEG LA believe anyone using Adobe
 444 Premiere and other video related software with a H.264 distribution
 445 license need a license agreement with MPEG LA to use such tools for
 446 anything non-private or commercial, while it is OK to set up a
 447 Youtube-like service as long as no-one pays to get access to the
 448 content.  I still have no clear idea how this applies to Norway, where
 449 none of the patents MPEG LA is licensing are valid.  Will the
 450 copyright terms take precedence or can those terms be ignored because
 451 the patents are not valid in Norway?</p>

 464       <div class="title"><a href="http://people.skolelinux.org/pere/blog/New_laptop___some_more_clues_and_ideas_based_on_feedback.html">New laptop - some more clues and ideas based on feedback</a></div>
 465       <div class="date"> 5th July 2015</div>
 466       <div class="body"><p>Several people contacted me after my previous blog post about my
 467 need for a new laptop, and provided very useful feedback.  I wish to
 468 thank every one of these.  Several pointed me to the possibility of
 469 fixing my X230, and I am already in the process of getting Lenovo to
 470 do so thanks to the on site, next day support contract covering the
 471 machine.  But the battery is almost useless (I expect to replace it
 472 with a non-official battery) and I do not expect the machine to live
 473 for many more years, so it is time to plan its replacement.  If I did
 474 not have a support contract, it was suggested to find replacement parts
 475 using <a href="http://www.francecrans.com/">FrancEcrans</a>, but it
 476 might present a language barrier as I do not understand French.</p>
 477
 478 <p>One tip I got was to use the
 479 <a href="https://skinflint.co.uk/?cat=nb">Skinflint</a> web service to
 480 compare laptop models.  It seem to have more models available than
 481 prisjakt.no.  Another tip I got from someone I know have similar
 482 keyboard preferences was that the HP EliteBook 840 keyboard is not
 483 very good, and this matches my experience with earlier EliteBook
 484 keyboards I tested.  Because of this, I will not consider it any further.
 485
 486 <p>When I wrote my blog post, I was not aware of Thinkpad X250, the
 487 newest Thinkpad X model.  The keyboard reintroduces mouse buttons
 488 (which is missing from the X240), and is working fairly well with
 489 Debian Sid/Unstable according to
 490 <a href="http://www.corsac.net/X250/">Corsac.net</a>.  The reports I
 491 got on the keyboard quality are not consistent.  Some say the keyboard
 492 is good, others say it is ok, while others say it is not very good.
 493 Those with experience from X41 and and X60 agree that the X250
 494 keyboard is not as good as those trusty old laptops, and suggest I
 495 keep and fix my X230 instead of upgrading, or get a used X230 to
 496 replace it.  I'm also told that the X250 lack leds for caps lock, disk
 497 activity and battery status, which is very convenient on my X230.  I'm
 498 also told that the CPU fan is running very often, making it a bit
 499 noisy.  In any case, the X250 do not work out of the box with Debian
 500 Stable/Jessie, one of my requirements.</p>
 501
 502 <p>I have also gotten a few vendor proposals, one was
 503 <a href="http://pro-star.com">Pro-Star</a>, another was
 504 <a href="http://shop.gluglug.org.uk/product/libreboot-x200/">Libreboot</a>.
 505 The latter look very attractive to me.</p>
 506
 507 <p>Again, thank you all for the very useful feedback.  It help a lot
 508 as I keep looking for a replacement.</p>
 509
 510 <p>Update 2015-07-06: I was recommended to check out the
 511 <a href="">lapstore.de</a> web shop for used laptops.  They got several
 512 different
 513 <a href="http://www.lapstore.de/f.php/shop/lapstore/f/411/lang/x/kw/Lenovo_ThinkPad_X_Serie/">old
 514 thinkpad X models</a>, and provide one year warranty.</p>

 529       <div class="body"><p>My primary work horse laptop is failing, and will need a
 530 replacement soon.  The left 5 cm of the screen on my Thinkpad X230
 531 started flickering yesterday, and I suspect the cause is a broken
 532 cable, as changing the angle of the screen some times get rid of the
 533 flickering.</p>
 534
 535 <p>My requirements have not really changed since I bought it, and is
 536 still as
 537 <a href="http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html">I
 538 described them in 2013</a>.  The last time I bought a laptop, I had
 539 good help from
 540 <a href="http://www.prisjakt.no/category.php?k=353">prisjakt.no</a>
 541 where I could select at least a few of the requirements (mouse pin,
 542 wifi, weight) and go through the rest manually.  Three button mouse
 543 and a good keyboard is not available as an option, and all the three
 544 laptop models proposed today (Thinkpad X240, HP EliteBook 820 G1 and
 545 G2) lack three mouse buttons).  It is also unclear to me how good the
 546 keyboard on the HP EliteBooks are.  I hope Lenovo have not messed up
 547 the keyboard, even if the quality and robustness in the X series have
 548 deteriorated since X41.</p>
 549
 550 <p>I wonder how I can find a sensible laptop when none of the options
 551 seem sensible to me?  Are there better services around to search the
 552 set of available laptops for features?  Please send me an email if you
 553 have suggestions.</p>
 554
 555 <p>Update 2015-07-23: I got a suggestion to check out the FSF
 556 <a href="http://www.fsf.org/resources/hw/endorsement/respects-your-freedom">list
 557 of endorsed hardware</a>, which is useful background information.</p>

 577 finally happened the last few days.  A few talks are missing because
 578 the speakers asked the organizers to not publish them, but most of the
 579 talks are available.  The talks are being broadcasted on RiksTV
 580 channel 50 and using multicast on Uninett, as well as being available

 633 <p>Part of the reason this took so long was that the scripts NUUG had
 634 to prepare a recording for publication were five years old and no
 635 longer worked with the current video processing tools (command line
 636 argument changes).  In addition, we needed better audio normalization,
 637 which sent me on a detour to

 655       <div class="body"><p>I en global verden med eierskap på tvers, trengs det informasjon om
 656 hvem som har kontrollen i selskaper og bedrifter.  Og for å få tilgang
 657 til slik informasjon for alle som ønsker å analysere eierskap, holder
 658 med ikke med nasjonale databaser over eierskap, det må globale
 659 samledatabaser med åpne data til.  Heldigvis finnes det en
 660 internasjonal bevegelse for å gjøre selskapsinformasjon for alle land
 661 offentlig tilgjengelig.  En slik database heter
 662 <a href="http://opencorporates.com">OpenCorporates</a>, der
 663 informasjonen er gratis tilgjengelig med en "del på samme
 664 vilkår"-lisens.  De samler inn selskapsinformasjon, eierskap,
 665 konsesjonstildelinger og lignende.  De manglet ganske mye for Norge,
 666 da bruksvilkårene til Norsk offentlig informasjon i stor grad
 667 blokkerer OpenCorporates fra å samle den inn.</p>
 668
 669 <p>Men jeg er jo involvert i
 670 <a href="http://www.frikanalen.no/">Frikanalen</a>, som har
 671 TV-konsesjon, og tenkte det kunne være fint om informasjon om alle
 672 mediakonsesjoner var tilgjengelig i OpenCorporates, så jeg sendte
 673 avgårde følgende spørsmål til Medietilsynet 2015-06-22:</p>
 674
 675 <blockquote>
 676 <p>Hei.  Finnes det en oversikt over enhetene som Mediatilsynet fører
 677 tilsyn med som åpne data?  Jeg lette etter den på
 678 &lt;URL:<a href="http://data.norge.no/">http://data.norge.no/</a>&gt; og
 679 &lt;URL:<a href="http://hotell.difi.no/">http://hotell.difi.no/</a>&gt; uten å
 680 finne noe der, og fant heller ikke noe under
 681 &lt;URL:<a href="http://www.medietilsynet.no/">http://www.medietilsynet.no/</a>&gt;.</p>
 682
 683 <p>Jeg tenker på alle som har fått kringkastingskonsesjon og alle som
 684 er omtalt under
 685 &lt;URL:<a href="http://www.medietilsynet.no/mediebildet/">http://www.medietilsynet.no/mediebildet/</a>&gt;.</p>
 686
 687 <p>Jeg skulle gjerne hatt dette maskinlesbart, og inkludert
 688 organisasjonsnummer og hva slags forhold mediatilsynet har til
 689 organisasjonene.  Tanken er å importere det i
 690 &lt;URL:<a href="https://opencorporates.com/">https://opencorporates.com/</a>&gt; for analyse, så det bør ikke ha
 691 bruksbegresninger som gjør dette umulig.</p>

 693

 695 tilgjengelig.  Svaret fra Hanne Sekkelsten hos Medietilsynet var
 696 informativt og imøtekommende.</p>

 756 <p>Desverre er formatene for ustrukturerte til maskinell behandling og

 796 <pre>
 797 % time ./bin/eierskap-dotty 958033540 > dagbladet.dot
 798
 799 real    0m2.841s
 800 user    0m0.184s
 801 sys     0m0.036s
 802 %
 803 </pre>
 804
 805 <p>The script accept several organisation numbers on the command line,
 806 allowing a cluster of companies to be graphed in the same image.  The
 807 resulting dot file for the example above look like this.  The edges
 808 are labeled with the ownership percentage, and the nodes uses the
 809 organisation number as their name and the name as the label:</p>
 810
 811 <pre>
 812 digraph ownership {
 813 rankdir = LR;
 814 "Aller Holding A/s" -> "910119877" [label="100%"]
 815 "910119877" -> "998689015" [label="100%"]
 816 "998689015" -> "958033540" [label="99%"]
 817 "974530600" -> "958033540" [label="1%"]
 818 "958033540" [label="AS DAGBLADET"]
 819 "998689015" [label="Berner Media Holding AS"]
 820 "974530600" [label="Dagbladets Stiftelse"]
 821 "910119877" [label="Aller Media AS"]
 822 }
 823 </pre>
 824
 825 <p>To view the ownership graph, run "<tt>dotty dagbladet.dot</tt>" or
 826 convert it to a PNG using "<tt>dot -T png dagbladet.dot >
 827 dagbladet.png</tt>".  The result can be seen below:</p>
 828
 829 <img src="http://people.skolelinux.org/pere/blog/images/2015-06-15-ownership-graphs-norway-dagbladet.png" width="80%">
 830
 831 <p>Note that I suspect the "Aller Holding A/S" entry to be incorrect
 832 data in the official ownership register, as that name is not
 833 registered in the official company register for Norway.  The ownership
 834 register is sensitive to typos and there seem to be no strict checking
 835 of the ownership links.</p>

 840 <p>Update 2015-06-15: Since the initial post I've been told that
 841 "<a href="http://www.proff.dk/firma/carl-allers-etablissement-aktieselskab/københavn-v/hovedkontorer/13624518-3/">Aller
 842 Holding A/S</a>" is a Danish company, which explain why it did not
 843 have a Norwegian organisation number.  I've also been told that there
 844 is a <a href="http://www.brreg.no/automatiske/webservices/">web
 845 services API available</a> from Brønnøysundsregistrene, for those
 846 willing to accept the terms or pay the price.</p>

 860       <div class="date">11th June 2015</div>
 861       <div class="body"><p>Television loudness is the source of frustration for viewers
 862 everywhere.  Some channels are very load, others are less loud, and
 863 ads tend to shout very high to get the attention of the viewers, and
 864 the viewers do not like this.  This fact is well known to the TV
 865 channels.  See for example the BBC white paper
 866 "<a href="http://downloads.bbc.co.uk/rd/pubs/whp/whp-pdf-files/WHP202.pdf">Terminology
 867 for loudness and level dBTP, LU, and all that</a>" from 2011 for a
 868 summary of the problem domain.  To better address the need for even
 869 loadness, the TV channels got together several years ago to agree on a
 870 new way to measure loudness in digital files as one step in
 871 standardizing loudness.  From this came the ITU-R standard BS.1770,
 872 "<a href="http://www.itu.int/rec/R-REC-BS.1770/en">Algorithms to
 873 measure audio programme loudness and true-peak audio level</a>".</p>
 874
 875 <p>The ITU-R BS.1770 specification describe an algorithm to measure
 876 loadness in LUFS (Loudness Units, referenced to Full Scale). But
 877 having a way to measure is not enough.  To get the same loudness
 878 across TV channels, one also need to decide which value to standardize
 879 on.  For European TV channels, this was done in the EBU Recommondaton
 880 R128, "<a href="https://tech.ebu.ch/docs/r/r128.pdf">Loudness
 881 normalisation and permitted maximum level of audio signals</a>", which
 882 specifies a recommended level of -23 LUFS.  In Norway, I have been
 883 told that NRK, TV2, MTG and SBS have decided among themselves to
 884 follow the R128 recommondation for playout from 2016-03-01.</p>
 885
 886 <p>There are free software available to measure and adjust the loudness
 887 level using the LUFS.  In Debian, I am aware of a library named
 888 <a href="https://tracker.debian.org/pkg/libebur128">libebur128</a>
 889 able to measure the loudness and since yesterday morning a new binary
 890 named <a href="http://bs1770gain.sourceforge.net">bs1770gain</a>
 891 capable of both measuring and adjusting was uploaded and is waiting
 892 for NEW processing.  I plan to maintain the latter in Debian under the
 893 <a href="https://qa.debian.org/developer.php?email=pkg-multimedia-maintainers%40lists.alioth.debian.org">Debian
 894 multimedia</a> umbrella.</p>
 895
 896 <p>The free software based TV channel I am involved in,
 897 <a href="http://www.frikanalen.no/">Frikanalen</a>, plan to follow the
 898 R128 recommondation ourself as soon as we can adjust the software to
 899 do so, and the bs1770gain tool seem like a good fit for that part of
 900 the puzzle to measure loudness on new video uploaded to Frikanalen.
 901 Personally, I plan to use bs1770gain to adjust the loudness of videos
 902 I upload to Frikanalen on behalf of <a href="http://www.nuug.no/">the
 903 NUUG member organisation</a>.  The program seem to be able to measure
 904 the LUFS value of any media file handled by ffmpeg, but I've only
 905 successfully adjusted the LUFS value of WAV files.  I suspect it
 906 should be able to adjust it for all the formats handled by ffmpeg.</p>
