  26 <p>Half a year ago I
  27 <a href="http://people.skolelinux.org/pere/blog/Officeshots_taking_shape.html">wrote
  28 a bit</a> about <a href="http://www.officeshots.org/">OfficeShots</a>,
  29 a web service to allow anyone to test how ODF documents are handled by
  30 the different programs reading and writing the ODF format.</p>
  31
  32 <p>I just had a look at the service, and it seem to be going strong.
  33 Very interesting to see the results reported in the gallery, how
  34 different Office implementations handle different ODF features.  Sad
  35 to see that KOffice was not doing it very well, and happy to see that
  36 LibreOffice has been tested already (but sadly not listed as a option
  37 for OfficeShots users yet).  I am glad to see that the ODF community
  38 got such a great test tool available.</p>

  54 <p>Jeg flikket litt på OpenStreetmap.org i går, og oppdaget ved en
  55 tilfeldighet at det er en rekke noder som representerer
  56 overvåkningskamera som ikke blir med på kartet med overvåkningskamera
  57 i Norge som
  58 <a href="http://people.skolelinux.org/pere/blog/Kart_over_overv__kningskamera_i_Norge.html">jeg
  59 laget</a> for snart to år siden.  Fra før tok jeg med noder merket med
  60 man_made=surveillance, mens det er en rekke noder som kun er merket
  61 med highway=speed_camera.  Endret på koden som henter ut kameralisten
  62 fra OSM, og vips er antall kamera økt til 165.</p>
  63
  64 <a href="http://people.skolelinux.no/pere/surveillance-norway/">Kartet</a>
  65 er fortsatt ikke komplett, så hvis du ser noen kamera som mangler,
  66 legg inn ved å følge instruksene fra

  68 Hvis du vet om noen flere måter å merke overvåkningskamera i OSM, ta
  69 kontakt slik at jeg kan få med også disse.</p>

  83   <div class="date">2010-12-22 14:55</div>
  84   <div class="body">
  85 <p>The last few days I have spent at work here at the <a
  86 href="http://www.uio.no/">University of oslo</a> testing if the new
  87 batch of computers will work with Linux.  Every year for the last few
  88 years the university have organized shared bid of a few thousand
  89 computers, and this year HP won the bid.  Two different desktops and
  90 five different laptops are on the list this year.  We in the UNIX
  91 group want to know which one of these computers work well with RHEL
  92 and Ubuntu, the two Linux distributions we currently handle at the
  93 university.</p>
  94
  95 <p>My test method is simple, and I share it here to get feedback and
  96 perhaps inspire others to test hardware as well.  To test, I PXE
  97 install the OS version of choice, and log in as my normal user and run
  98 a few applications and plug in selected pieces of hardware.  When
  99 something fail, I make a note about this in the test matrix and move
 100 on.  If I have some spare time I try to report the bug to the OS
 101 vendor, but as I only have the machines for a short time, I rarely
 102 have the time to do this for all the problems I find.</p>
 103
 104 <p>Anyway, to get to the point of this post.  Here is the simple tests
 105 I perform on a new model.</p>
 106
 107 <ul>
 108
 109 <li>Is PXE installation working?  I'm testing with RHEL6, Ubuntu Lucid
 110 and Ubuntu Maverik at the moment.  If I feel like it, I also test with
 111 RHEL5 and Debian Edu/Squeeze.</li>
 112
 113 <li>Is X.org working?  If the graphical login screen show up after
 114 installation, X.org is working.</li>
 115
 116 <li>Is hardware accelerated OpenGL working?  Running glxgears (in
 117 package mesa-utils on Ubuntu) and writing down the frames per second
 118 reported by the program.</li>
 119
 120 <li>Is sound working?  With Gnome and KDE, a sound is played when
 121 logging in, and if I can hear this the test is successful.  If there
 122 are several audio exits on the machine, I try them all and check if
 123 the Gnome/KDE audio mixer can control where to send the sound.  I
 124 normally test this by playing
 125 <a href="http://www.nuug.no/aktiviteter/20101012-chef/ ">a HTML5
 126 video</a> in Firefox/Iceweasel.</li>
 127
 128 <li>Is the USB subsystem working?  I test this by plugging in a USB
 129 memory stick and see if Gnome/KDE notices this.</li>
 130
 131 <li>Is the CD/DVD player working?  I test this by inserting any CD/DVD
 132 I have lying around, and see if Gnome/KDE notices this.</li>
 133
 134 <li>Is any built in camera working?  Test using cheese, and see if a
 135 picture from the v4l device show up.</li>
 136
 137 <li>Is bluetooth working?  Use the Gnome/KDE browsing tool to see if
 138 any bluetooth devices are discovered.  In my office, I normally see a
 139 few.</li>
 140
 141 <li>For laptops, is the SD or Compaq Flash reader working.  I have
 142 memory modules lying around, and stick them in and see if Gnome/KDE
 143 notice this.</li>
 144
 145 <li>For laptops, is suspecd/hibernate working?  I'm testing if the
 146 special button work, and if the laptop continue to work after
 147 resume.</li>
 148
 149 <li>For laptops, is the extra buttons working, like audio level,
 150 adjusting background light, switching on/off external video output,
 151 switching on/off wifi, bluetooth, etc?  The set of buttons differ from
 152 laptop to laptop, so I just write down which are working and which are
 153 not.</li>
 154
 155 <li>Some laptops have smart card readers, finger print readers,
 156 acceleration sensors etc.  I rarely test these, as I do not know how
 157 to quickly test if they are working or not, so I only document their
 158 existence.</li>
 159
 160 </ul>
 161
 162 <p>By now I suspect you are really curious what the test results are
 163 for the HP machines I am testing.  I'm not done yet, so I will report
 164 the test results later.  For now I can report that HP 8100 Elite work
 165 fine, and hibernation fail with HP EliteBook 8440p on Ubuntu Lucid,
 166 and audio fail on RHEL6.  Ubuntu Maverik worked with 8440p.  As you
 167 can see, I have most machines left to test.  One interesting
 168 observation is that Ubuntu Lucid has almost twice the framerate than
 169 RHEL6 with glxgears.  No idea why.</p>

 183   <div class="date">2010-12-11 15:10</div>
 184   <div class="body">
 185 <p>As I continue to explore
 186 <a href="http://www.bitcoin.org/">BitCoin</a>, I've starting to wonder
 187 what properties the system have, and how it will be affected by laws
 188 and regulations here in Norway.  Here are some random notes.</p>
 189
 190 <p>One interesting thing to note is that since the transactions are
 191 verified using a peer to peer network, all details about a transaction
 192 is known to everyone.  This means that if a BitCoin address has been
 193 published like I did with mine in my initial post about BitCoin, it is
 194 possible for everyone to see how many BitCoins have been transfered to
 195 that address.  There is even a web service to look at the details for
 196 all transactions.  There I can see that my address
 197 <a href="http://blockexplorer.com/address/15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a>
 198 have received 16.06 Bitcoin, the
 199 <a href="http://blockexplorer.com/address/1LfdGnGuWkpSJgbQySxxCWhv8MHqvwst3">1LfdGnGuWkpSJgbQySxxCWhv8MHqvwst3</a>
 200 address of Simon Phipps have received 181.97 BitCoin and the address
 201 <a href="http://blockexplorer.com/address/1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt">1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt</A>
 202 of EFF have received 2447.38 BitCoins so far.  Thank you to each and
 203 every one of you that donated bitcoins to support my activity. The
 204 fact that anyone can see how much money was transfered to a given
 205 address make it more obvious why the BitCoin community recommend to
 206 generate and hand out a new address for each transaction.  I'm told
 207 there is no way to track which addresses belong to a given person or
 208 organisation without the person or organisation revealing it
 209 themselves, as Simon, EFF and I have done.</p>
 210
 211 <p>In Norway, and in most other countries, there are laws and
 212 regulations limiting how much money one can transfer across the border
 213 without declaring it.  There are money laundering, tax and accounting
 214 laws and regulations I would expect to apply to the use of BitCoin.
 215 If the Skolelinux foundation
 216 (<a href="http://linuxiskolen.no/slxdebianlabs/donations.html">SLX
 217 Debian Labs</a>) were to accept donations in BitCoin in addition to
 218 normal bank transfers like EFF is doing, how should this be accounted?
 219 Given that it is impossible to know if money can across the border or
 220 not, should everything or nothing be declared?  What exchange rate
 221 should be used when calculating taxes?  Would receivers have to pay
 222 income tax if the foundation were to pay Skolelinux contributors in
 223 BitCoin?  I have no idea, but it would be interesting to know.</p>
 224
 225 <p>For a currency to be useful and successful, it must be trusted and
 226 accepted by a lot of users.  It must be possible to get easy access to
 227 the currency (as a wage or using currency exchanges), and it must be
 228 easy to spend it.  At the moment BitCoin seem fairly easy to get
 229 access to, but there are very few places to spend it.  I am not really
 230 a regular user of any of the vendor types currently accepting BitCoin,
 231 so I wonder when my kind of shop would start accepting BitCoins.  I
 232 would like to buy electronics, travels and subway tickets, not herbs
 233 and books. :) The currency is young, and this will improve over time
 234 if it become popular, but I suspect regular banks will start to lobby
 235 to get BitCoin declared illegal if it become popular.  I'm sure they
 236 will claim it is helping fund terrorism and money laundering (which
 237 probably would be true, as is any currency in existence), but I
 238 believe the problems should be solved elsewhere and not by blaming
 239 currencies.</p>
 240
 241 <p>The process of creating new BitCoins is called mining, and it is
 242 CPU intensive process that depend on a bit of luck as well (as one is
 243 competing against all the other miners currently spending CPU cycles
 244 to see which one get the next lump of cash).  The "winner" get 50
 245 BitCoin when this happen.  Yesterday I came across the obvious way to
 246 join forces to increase ones changes of getting at least some coins,
 247 by coordinating the work on mining BitCoins across several machines
 248 and people, and sharing the result if one is lucky and get the 50
 249 BitCoins.  Check out
 250 <a href="http://www.bluishcoder.co.nz/bitcoin-pool/">BitCoin Pool</a>
 251 if this sounds interesting.  I have not had time to try to set up a
 252 machine to participate there yet, but have seen that running on ones
 253 own for a few days have not yield any BitCoins througth mining
 254 yet.</p>
 255
 256 <p>Update 2010-12-15: Found an <a
 257 href="http://inertia.posterous.com/reply-to-the-underground-economist-why-bitcoi">interesting
 258 criticism</a> of bitcoin.  Not quite sure how valid it is, but thought
 259 it was interesting to read.  The arguments presented seem to be
 260 equally valid for gold, which was used as a currency for many years.</p>

 312 <a href="http://www.salon.com/technology/dan_gillmor/2010/12/06/war_on_speech">free
 313 speech</a>, it has become obvious that PayPal, visa and mastercard can
 314 not be trusted to handle money transactions.
 315 A blog post from
 316 <a href="http://webmink.com/2010/12/06/now-accepting-bitcoin/">Simon
 317 Phipps on bitcoin</a> reminded me about a project that a friend of
 318 mine mentioned earlier.  I decided to follow Simon's example, and get
 319 involved with <a href="http://www.bitcoin.org/">BitCoin</a>.  I got
 320 some help from my friend to get it all running, and he even handed me
 321 some bitcoins to get started.  I even donated a few bitcoins to Simon
 322 for helping me remember BitCoin.</p>
 323
 324 <p>So, what is bitcoins, you probably wonder?  It is a digital
 325 crypto-currency, decentralised and handled using peer-to-peer
 326 networks.  It allows anonymous transactions and prohibits central
 327 control over the transactions, making it impossible for governments
 328 and companies alike to block donations and other transactions.  The
 329 source is free software, and while the key dependency wxWidgets 2.9
 330 for the graphical user interface is missing in Debian, the command
 331 line client builds just fine.  Hopefully Jonas
 332 <a href="http://bugs.debian.org/578157">will get the package into
 333 Debian</a> soon.</p>
 334
 335 <p>Bitcoins can be converted to other currencies, like USD and EUR.
 336 There are <a href="http://www.bitcoin.org/trade">companies accepting
 337 bitcoins</a> when selling services and goods, and there are even
 338 currency "stock" markets where the exchange rate is decided.  There
 339 are not many users so far, but the concept seems promising.  If you
 340 want to get started and lack a friend with any bitcoins to spare,
 341 you can even get
 342 <a href="https://freebitcoins.appspot.com/">some for free</a> (0.05
 343 bitcoin at the time of writing).  Use
 344 <a href="http://www.bitcoinwatch.com/">BitcoinWatch</a> to keep an eye
 345 on the current exchange rates.</p>
 346
 347 <p>As an experiment, I have decided to set up bitcoind on one of my
 348 machines.  If you want to support my activity, please send Bitcoin
 349 donations to the address
 350 <b>15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</b>.  Thank you!</p>

 397 rulleblad, og med unntak av to fartsbøter har jeg aldri vært en byrde
 398 for samfunnet. Det akter jeg å fortsette med. Det er mange som meg,
 399 lovlydige, pliktoppfyllende borgere som aldri vil utgjøre en trussel
 400 mot noe som helst. Vi synes derfor det er trist og sårende at all vår

 437 <p>A few days ago, I was introduces to some students in the robot
 438 student assosiation <a href="http://www.robotica.no/">Robotica
 439 Osloensis</a> at the University of Oslo where I work, who planned to
 440 get their own 3D printer.  They wanted to learn from me based on my
 441 work in the area.  After having a short lunch meeting with them, I
 442 offered them to borrow my reprap kit, as I never had time to complete
 443 the build and this seem unlike to change any time soon.  I look
 444 forward to see how this goes.  This monday their volunteer driver
 445 picked up my kit and drove it to their lab, and tomorrow I am told the
 446 last exam is over so they can start work on getting the 3D printer
 447 operational.</p>
 448
 449 <p>The robotic group have already build several robots on their own,
 450 and seem capable of getting the reprap operational.  I really look
 451 forward to being able to print all the cool 3D designs published on
 452 <a href="http://www.thingiverse.com/">Thingiverse</a>.  I even got
 453 some 3D scans I got made during Dagen@IFI when one of the groups at
 454 the computer science department at the university demonstrated their
 455 very cool 3D scanner.</p>

 499   <div class="date">2010-11-27 11:30</div>
 500   <div class="body">
 501 <p>In the latest issue of Linux Journal, the readers choices were
 502 presented, and the winner among the multimedia player were VLC.
 503 Personally, I like VLC, and it is my player of choice when I first try
 504 to play a video file or stream.  Only if VLC fail will I drag out
 505 gmplayer to see if it can do better.  The reason is mostly the failure
 506 model and trust.  When VLC fail, it normally pop up a error message
 507 reporting the problem.  When mplayer fail, it normally segfault or
 508 just hangs.  The latter failure mode drain my trust in the program.<p>
 509
 510 <p>But even if VLC is my player of choice, we have choosen to use
 511 mplayer in <a href="http://www.skolelinux.org/">Debian
 512 Edu/Skolelinux</a>.  The reason is simple.  We need a good browser
 513 plugin to play web videos seamlessly, and the VLC browser plugin is
 514 not very good.  For example, it lack in-line control buttons, so there
 515 is no way for the user to pause the video.  Also, when I
 516 <a href="http://wiki.debian.org/DebianEdu/BrowserMultimedia">last
 517 tested the browser plugins</a> available in Debian, the VLC plugin
 518 failed on several video pages where mplayer based plugins worked.  If
 519 the browser plugin for VLC was as good as the gecko-mediaplayer
 520 package (which uses mplayer), we would switch.</P>
 521
 522 <p>While VLC is a good player, its user interface is slightly
 523 annoying.  The most annoying feature is its inconsistent use of
 524 keyboard shortcuts.  When the player is in full screen mode, its
 525 shortcuts are different from when it is playing the video in a window.
 526 For example, space only work as pause when in full screen mode.  I
 527 wish it had consisten shortcuts and that space also would work when in
 528 window mode.  Another nice shortcut in gmplayer is [enter] to restart
 529 the current video.  It is very nice when playing short videos from the
 530 web and want to restart it when new people arrive to have a look at
 531 what is going on.</p>
