  25   <div class="body">
  26 <p>As I continue to explore
  27 <a href="http://www.bitcoin.org/">BitCoin</a>, I've starting to wonder
  28 what properties the system have, and how it will be affected by laws
  29 and regulations here in Norway.  Here are some random notes.</p>
  30
  31 <p>One interesting thing to note is that since the transactions are
  32 verified using a peer to peer network, all details about a transaction
  33 is known to everyone.  This means that if a BitCoin address has been
  34 published like I did with mine in my initial post about BitCoin, it is
  35 possible for everyone to see how many BitCoins have been transfered to
  36 that address.  There is even a web service to look at the details for
  37 all transactions.  There I can see that my address
  38 <a href="http://blockexplorer.com/address/15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a>
  39 have received 16.06 Bitcoin, the
  40 <a href="http://blockexplorer.com/address/1LfdGnGuWkpSJgbQySxxCWhv8MHqvwst3">1LfdGnGuWkpSJgbQySxxCWhv8MHqvwst3</a>
  41 address of Simon Phipps have received 181.97 BitCoin and the address
  42 <a href="http://blockexplorer.com/address/1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt">1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt</A>
  43 of EFF have received 2447.38 BitCoins so far.  Thank you to each and
  44 every one of you that donated bitcoins to support my activity. The
  45 fact that anyone can see how much money was transfered to a given
  46 address make it more obvious why the BitCoin community recommend to
  47 generate and hand out a new address for each transaction.  I'm told
  48 there is no way to track which addresses belong to a given person or
  49 organisation without the person or organisation revealing it
  50 themselves, as Simon, EFF and I have done.</p>
  51
  52 <p>In Norway, and in most other countries, there are laws and
  53 regulations limiting how much money one can transfer across the border
  54 without declaring it.  There are money laundering, tax and accounting
  55 laws and regulations I would expect to apply to the use of BitCoin.
  56 If the Skolelinux foundation
  57 (<a href="http://linuxiskolen.no/slxdebianlabs/donations.html">SLX
  58 Debian Labs</a>) were to accept donations in BitCoin in addition to
  59 normal bank transfers like EFF is doing, how should this be accounted?
  60 Given that it is impossible to know if money can across the border or
  61 not, should everything or nothing be declared?  What exchange rate
  62 should be used when calculating taxes?  Would receivers have to pay
  63 income tax if the foundation were to pay Skolelinux contributors in
  64 BitCoin?  I have no idea, but it would be interesting to know.</p>
  65
  66 <p>For a currency to be useful and successful, it must be trusted and
  67 accepted by a lot of users.  It must be possible to get easy access to
  68 the currency (as a wage or using currency exchanges), and it must be
  69 easy to spend it.  At the moment BitCoin seem fairly easy to get
  70 access to, but there are very few places to spend it.  I am not really
  71 a regular user of any of the vendor types currently accepting BitCoin,
  72 so I wonder when my kind of show would start accepting BitCoins.  I
  73 would like to buy electronics, travels and subway tickets, not herbs
  74 and books. :) The currency is young, and this will improve over time
  75 if it become popular, but I suspect regular banks will start to lobby
  76 to get BitCoin declared illegal if it become popular.  I'm sure they
  77 will claim it is helping fund terrorism and money laundering (which
  78 probably would be true, as is any currency in existence), but I
  79 believe the problems should be solved elsewhere and not by blaming
  80 currencies.</p>
  81
  82 <p>The process of creating new BitCoins is called mining, and it is
  83 CPU intensive process that depend on a bit of luck as well (as one is
  84 competing against all the other miners currently spending CPU cycles
  85 to see which one get the next lump of cash.  The "winner" get 50
  86 BitCoin when this happen.  Yesterday I came across the obvious way to
  87 join forces to increase ones changes of getting at least some coins,
  88 by coordinating the work on mining BitCoins across several machines
  89 and people, and sharing the result if one is lucky and get the 50
  90 BitCoins.  Check out
  91 <a href="http://www.bluishcoder.co.nz/bitcoin-pool/">BitCoin Pool</a>
  92 if this sounds interesting.  I have not had time to try to set up a
  93 machine to participate there yet.</p>

 147 not be trusted to handle money transactions.
 148 A blog post from
 149 <a href="http://webmink.com/2010/12/06/now-accepting-bitcoin/">Simon
 150 Phipps on bitcoin</a> reminded me about a project that a friend of
 151 mine mentioned earlier.  I decided to follow Simon's example, and get
 152 involved with <a href="http://www.bitcoin.org/">BitCoin</a>.  I got
 153 some help from my friend to get it all running, and he even handed me
 154 some bitcoins to get started.  I even donated a few bitcoins to Simon
 155 for helping me remember BitCoin.</p>
 156
 157 <p>So, what is bitcoins, you probably wonder?  It is a digital
 158 crypto-currency, decentralised and handled using peer-to-peer
 159 networks.  It allows anonymous transactions and prohibits central
 160 control over the transactions, making it impossible for governments
 161 and companies alike to block donations and other transactions.  The
 162 source is free software, and while the key dependency wxWidgets 2.9
 163 for the graphical user interface is missing in Debian, the command
 164 line client builds just fine.  Hopefully Jonas
 165 <a href="http://bugs.debian.org/578157">will get the package into
 166 Debian</a> soon.</p>
 167
 168 <p>Bitcoins can be converted to other currencies, like USD and EUR.
 169 There are <a href="http://www.bitcoin.org/trade">companies accepting
 170 bitcoins</a> when selling services and goods, and there are even
 171 currency "stock" markets where the exchange rate is decided.  There
 172 are not many users so far, but the concept seems promising.  If you
 173 want to get started and lack a friend with any bitcoins to spare,
 174 you can even get
 175 <a href="https://freebitcoins.appspot.com/">some for free</a> (0.05
 176 bitcoin at the time of writing).  Use
 177 <a href="http://www.bitcoinwatch.com/">BitcoinWatch</a> to keep an eye
 178 on the current exchange rates.</p>
 179
 180 <p>As an experiment, I have decided to set up bitcoind on one of my
 181 machines.  If you want to support my activity, please send Bitcoin
 182 donations to the address
 183 <b>15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</b>.  Thank you!</p>

 201 følgende
 202 <a href="http://www.bekkelund.net/2010/12/09/en-stille-bonn/">korte
 203 oppsummering</a> rundt datalagringsdirektivet, som jeg videreformidler
 204 her.</p>
 205
 206 <p><blockquote><strong>Det pågår i disse dager en intens diskusjon om
 207 innføring av Datalagringsdirektivet (<acronym
 208 title="Datalagringsdirektivet">DLD</acronym>) i norsk rett. Kanskje
 209 har du gjort deg opp en mening, kanskje er du usikker. I begge
 210 tilfeller ber jeg deg lese videre.</strong></p>
 211
 212 <p>Samtlige fagmiljøer, både i Norge og EU, har konkludert med at
 213 <acronym title="Datalagringsdirektivet">DLD</acronym> ikke bør
 214 innføres på nåværende tidspunkt. Den tekniske kvaliteten på direktivet
 215 er dårlig, det griper uforholdsmessig inn i personvernet, det har
 216 store mangler og viktige spørsmål som hvem som skal ha tilgang og
 217 hvordan data skal lagres er fortsatt uavklart.</p>
 218
 219 <ul>
 220 <li><a href="http://ikt-norge.no/norge-kan-slippe-datalagringsdirektivet/">EU-ekspertene sier</a> at konsekvensene av å benytte vetoretten er minimale</li>

 223 <li><a href="http://www.bekkelund.net/?s=dld">Teknologene sier</a> at sikker lagring ikke er mulig, at det er svært enkelt å omgå og mulig å manipulere data og produsere falske beviser</li>

Blant annet har den tyske forfatningsdomstolen funnet at måten <acronym title="Datalagringsdirektivet">DLD</acronym> er innført på er i strid med tysk grunnlov</li>
 226 <li>Alle de store <a href="http://www.bekkelund.net/2010/12/08/lokasjonsdata-og-datalagringsdirektivet/">operatørene og tilbyderne sier nei</a>, av tekniske og personvernmessige årsaker</li>
 227 </ul>
 228
 229 <p>Jeg liker å tro at jeg er en hyggelig fyr. Jeg har et rent
 230 rulleblad, og med unntak av to fartsbøter har jeg aldri vært en byrde
 231 for samfunnet. Det akter jeg å fortsette med. Det er mange som meg,
 232 lovlydige, pliktoppfyllende borgere som aldri vil utgjøre en trussel
 233 mot noe som helst. Vi synes derfor det er trist og sårende at all vår
 234 atferd skal overvåkes døgnkontinuerlig.</p>

 271 student assosiation <a href="http://www.robotica.no/">Robotica
 272 Osloensis</a> at the University of Oslo where I work, who planned to
 273 get their own 3D printer.  They wanted to learn from me based on my
 274 work in the area.  After having a short lunch meeting with them, I
 275 offered them to borrow my reprap kit, as I never had time to complete
 276 the build and this seem unlike to change any time soon.  I look
 277 forward to see how this goes.  This monday their volunteer driver
 278 picked up my kit and drove it to their lab, and tomorrow I am told the
 279 last exam is over so they can start work on getting the 3D printer
 280 operational.</p>
 281
 282 <p>The robotic group have already build several robots on their own,

 332   <div class="date">2010-11-27 11:30</div>
 333   <div class="body">
 334 <p>In the latest issue of Linux Journal, the readers choices were
 335 presented, and the winner among the multimedia player were VLC.
 336 Personally, I like VLC, and it is my player of choice when I first try
 337 to play a video file or stream.  Only if VLC fail will I drag out
 338 gmplayer to see if it can do better.  The reason is mostly the failure
 339 model and trust.  When VLC fail, it normally pop up a error message
 340 reporting the problem.  When mplayer fail, it normally segfault or
 341 just hangs.  The latter failure mode drain my trust in the program.<p>
 342
 343 <p>But even if VLC is my player of choice, we have choosen to use
 344 mplayer in <a href="http://www.skolelinux.org/">Debian
 345 Edu/Skolelinux</a>.  The reason is simple.  We need a good browser
 346 plugin to play web videos seamlessly, and the VLC browser plugin is
 347 not very good.  For example, it lack in-line control buttons, so there
 348 is no way for the user to pause the video.  Also, when I
 349 <a href="http://wiki.debian.org/DebianEdu/BrowserMultimedia">last
 350 tested the browser plugins</a> available in Debian, the VLC plugin
 351 failed on several video pages where mplayer based plugins worked.  If
 352 the browser plugin for VLC was as good as the gecko-mediaplayer
 353 package (which uses mplayer), we would switch.</P>
 354
 355 <p>While VLC is a good player, its user interface is slightly
 356 annoying.  The most annoying feature is its inconsistent use of
 357 keyboard shortcuts.  When the player is in full screen mode, its
 358 shortcuts are different from when it is playing the video in a window.
 359 For example, space only work as pause when in full screen mode.  I
 360 wish it had consisten shortcuts and that space also would work when in
 361 window mode.  Another nice shortcut in gmplayer is [enter] to restart
 362 the current video.  It is very nice when playing short videos from the
 363 web and want to restart it when new people arrive to have a look at
 364 what is going on.</p>

 380 <p>Jeg registrerer med vond smak i munnen at Den Norske Dataforening
 381 <a
 382 href="http://www.dataforeningen.no/hedret-med-rosingprisen.4849070-133913.html">hedrer
 383 overvåkning av barn med Rosingsprisen for kreativitet i år</a>.  Jeg
 384 er glad jeg nå er meldt ut av DND.</p>
 385
 386 <p>Å elektronisk overvåke sine barn er ikke å gjøre dem en tjeneste,
 387 men et overgrep mot individer i utvikling som bør læres opp til å ta
 388 egne valg.</p>
 389
 390 <p>For å sitere Datatilsynets nye leder, Bjørn Erik Thon, i
 391 <a href="http://www.idg.no/computerworld/article174262.ece">et intervju
 392 med Computerworld Norge</A>:</p>
 393
 394 <p><blockquote>
 395 - For alle som har barn, meg selv inkludert, er førstetanken at det
 396 hadde vært fint å vite hvor barnet sitt er til enhver tid. Men ungene
 397 har ikke godt av det. De er små individer som skal søke rundt og finne
 398 sine små gjemmesteder og utvide horisonten, uten at foreldrene ser dem
 399 i kortene. Det kan være fristende, men jeg ville ikke gått inn i
 400 dette.
 401 </blockquote></p>
 402
 403 <p>Det er skremmende å se at DND mener en tjeneste som legger opp til
 404 slike overgrep bør hedres.  Å flytte oppveksten for barn inn i en
 405 virtuell
 406 <a href="http://en.wikipedia.org/wiki/Panopticon">Panopticon</a> er et
 407 grovt overgrep og vil gjøre skade på barnenes utvikling, og foreldre
 408 burde tenke seg godt om før de gir etter for sine instinkter her.</p>
 409
 410 <p>Blipper-tjenesten får meg til å tenke på bøkene til
 411 <a href="http://en.wikipedia.org/wiki/John_Twelve_Hawks">John Twelve
 412 Hawks</a>, som forbilledlig beskriver hvordan et totalitært
 413 overvåkningssamfunn bygges sakte men sikkert rundt oss, satt sammen av
 414 gode intensjoner og manglende bevissthet om hvilke prinsipper et
 415 liberalt demokrati er fundamentert på.  Jeg har hatt stor glede av å
 416 lese alle de tre bøkene.</p>

 432 <p>Michael Biebl suggested to me on IRC, that I changed my automated
 433 upgrade testing of the
 434 <a href="http://people.skolelinux.org/~pere/debian-upgrade-testing/">Lenny
 435 Gnome and KDE Desktop</a> to do <tt>apt-get autoremove</tt> when using apt-get.
 436 This seem like a very good idea, so I adjusted by test scripts and
 437 can now present the updated result from today:</p>

 865 <p>Running apt-get autoremove made the results using apt-get and
 866 aptitude a bit more similar, but there are still quite a lott of
 867 differences.  I have no idea what packages should be installed after
 868 the upgrade, but hope those that do can have a look.</p>

 884 <p>Most of the computers in use by the
 885 <a href="http://www.skolelinux.org/">Debian Edu/Skolelinux project</a>
 886 are virtual machines.  And they have been Xen machines running on a
 887 fairly old IBM eserver xseries 345 machine, and we wanted to migrate
 888 them to KVM on a newer Dell PowerEdge 2950 host machine.  This was a
 889 bit harder that it could have been, because we set up the Xen virtual
 890 machines to get the virtual partitions from LVM, which as far as I
 891 know is not supported by KVM.  So to migrate, we had to convert
 892 several LVM logical volumes to partitions on a virtual disk file.</p>
 893
 894 <p>I found
 895 <a href="http://searchnetworking.techtarget.com.au/articles/35011-Six-steps-for-migrating-Xen-virtual-machines-to-KVM">a
 896 nice recipe</a> to do this, and wrote the following script to do the
 897 migration.  It uses qemu-img from the qemu package to make the disk
 898 image, parted to partition it, losetup and kpartx to present the disk
 899 image partions as devices, and dd to copy the data.  I NFS mounted the
 900 new servers storage area on the old server to do the migration.</p>
