  25       <div class="body"><p>Keeping your DVD collection safe from scratches and curious
  26 children fingers while still having it available when you want to see a
  27 movie is not straight forward.  My preferred method at the moment is
  28 to store a full copy of the ISO on a hard drive, and use VLC, Popcorn
  29 Hour or other useful players to view the resulting file.  This way the
  30 subtitles and bonus material are still available and using the ISO is
  31 just like inserting the original DVD record in the DVD player.</p>
  32
  33 <p>Earlier I used dd for taking security copies, but it do not handle
  34 DVDs giving read errors (which are quite a few of them).  I've also
  35 tried using
  36 <a href="http://people.skolelinux.org/pere/blog/Ripping_problematic_DVDs_using_dvdbackup_and_genisoimage.html">dvdbackup
  37 and genisoimage</a>, but these days I use the marvellous python library
  38 and program
  39 <a href="http://bblank.thinkmo.de/blog/new-software-python-dvdvideo">python-dvdvideo</a>
  40 written by Bastian Blank.  It is
  41 <a href"http://packages.qa.debian.org/p/python-dvdvideo.html">in Debian
  42 already</a> and the binary package name is python3-dvdvideo. Instead
  43 of trying to read every block from the DVD, it parses the file
  44 structure and figure out which block on the DVD is actually in used,
  45 and only read those blocks from the DVD.  This work surprisingly well,
  46 and I have been able to almost backup my entire DVD collection using
  47 this method.</p> So far, python-dvdvideo have failed on between 10 and
  48 20 DVDs, which is a small fraction of my collection.  The most common
  49 problem is
  50 <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720831">DVDs
  51 using UTF-16 instead of UTF-8 characters</a>, which according to
  52 Bastian is against the DVD specification (and seem to cause some
  53 players to fail too).  A rarer problem is what seem to be inconsistent
  54 DVD structures, as the python library
  55 <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079">claim
  56 there is a overlap between objects</a>.  An equally rare problem claim
  57 <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741878">some
  58 value is out of range</a>.  No idea what is going on there.  I wish I
  59 knew enough about the DVD format to fix these, to ensure my movie
  60 collection will stay with me in the future.</p>
  61
  62 <p>So, if you need to keep your DVDs safe, back them up using
  63 python-dvdvideo. :)</p>

  78       <div class="body"><p>Det offentlige Norge har mye kunnskap og informasjon.  Men hvordan
  79 kan en få tilgang til den på en enkel måte?  Takket være et lite
  80 knippe lover og tilhørende forskrifter, blant annet
  81 <a href="http://lovdata.no/dokument/NL/lov/2006-05-19-16">offentlighetsloven</a>,
  82 <a href="http://lovdata.no/dokument/NL/lov/2003-05-09-31">miljøinformasjonsloven</a>
  83 og
  84 <a href="http://lovdata.no/dokument/NL/lov/1967-02-10/">forvaltningsloven</a>
  85 har en rett til å spørre det offentlige og få svar.  Men det finnes
  86 intet offentlig arkiv over hva andre har spurt om, og dermed risikerer en
  87 å måtte forstyrre myndighetene gang på gang for å få tak i samme
  88 informasjonen på nytt.  <a href="http://www.mysociety.org/">Britiske
  89 mySociety</a> har laget tjenesten
  90 <a href="http://www.whatdotheyknow.com/">WhatDoTheyKnow</a> som gjør
  91 noe med dette.  I Storbritannia blir WhatdoTheyKnow brukt i
  92 <a href="http://www.mysociety.org/2011/07/01/whatdotheyknows-share-of-central-government-foi-requests-q2-2011/">ca
  93 15% av alle innsynsforespørsler mot sentraladministrasjonen</a>.
  94 Prosjektet heter <a href="http://www.alaveteli.org/">Alaveteli</A>, og
  95 er takk i bruk en rekke steder etter at løsningen ble generalisert og
  96 gjort mulig å oversette.  Den hjelper borgerne med å be om innsyn,
  97 rådgir ved purringer og klager og lar alle se hvilke henvendelser som
  98 er sendt til det offentlige og hvilke svar som er kommet inn, i et
  99 søkpart arkiv.  Her i Norge holder vi i foreningen NUUG på å få opp en
 100 norsk utgave av Alaveteli, og her trenger vi din hjelp med
 101 oversettelsen.</p>
 102
 103 <p>Så langt er 76 % av Alaveteli oversatt til norsk bokmål, men vi
 104 skulle gjerne vært oppe i 100 % før lansering.  Oversettelsen gjøres
 105 på <a href="https://www.transifex.com/projects/p/alaveteli/">Transifex,
 106 der enhver som registrerer seg</a> og ber om tilgang til
 107 bokmålsoversettelsen får bidra.  Vi har satt opp en test av tjenesten
 108 (som ikke sender epost til det offentlige, kun til oss som holder på å
 109 sette opp tjenesten) på maskinen
 110 <a href="http://alaveteli-dev.nuug.no/">alaveteli-dev.nuug.no</a>, der
 111 en kan se hvordan de oversatte meldingen blir seende ut på nettsiden.
 112 Når tjenesten lanseres vil den hete
 113 <a href="https://www.mimesbrønn.no/">Mimes brønn</a>, etter
 114 visdomskilden som Odin måtte gi øyet sitt for å få drikke i.  Den
 115 nettsiden er er ennå ikke klar til bruk.</p>
 116
 117 <p>Hvis noen vil oversette til nynorsk også, så skal vi finne ut
 118 hvordan vi lager en flerspråklig tjeneste.  Men i første omgang er
 119 fokus på bokmålsoversettelsen, der vi selv har nok peiling til å ha
 120 fått oversatt 76%, men trenger hjelp for å komme helt i mål. :)</p>

 134       <div class="date">14th March 2014</div>
 135       <div class="body"><p>The <a href="https://wiki.debian.org/FreedomBox">Freedombox
 136 project</a> is working on providing the software and hardware for
 137 making it easy for non-technical people to host their data and
 138 communication at home, and being able to communicate with their
 139 friends and family encrypted and away from prying eyes.  It has been
 140 going on for a while, and is slowly progressing towards a new test
 141 release (0.2).</p>
 142
 143 <p>And what day could be better than the Pi day to announce that the
 144 new version will provide "hard drive" / SD card / USB stick images for
 145 Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization
 146 system), and can also be installed using a Debian installer preseed
 147 file.  The Debian based Freedombox is now based on Debian Jessie,
 148 where most of the needed packages used are already present.  Only one,
 149 the freedombox-setup package, is missing.  To try to build your own
 150 boot image to test the current status, fetch the freedom-maker scripts
 151 and build using
 152 <a href="http://packages.qa.debian.org/vmdebootstrap">vmdebootstrap</a>
 153 with a user with sudo access to become root:
 154
 155 <pre>
 156 git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
 157   freedom-maker
 158 sudo apt-get install git vmdebootstrap mercurial python-docutils \
 159   mktorrent extlinux virtualbox qemu-user-static binfmt-support \
 160   u-boot-tools
 161 make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
 162 </pre>
 163
 164 <p>Root access is needed to run debootstrap and mount loopback
 165 devices.  See the README for more details on the build. If you do not
 166 want all three images, trim the make line.  But note that thanks to <a
 167 href="https://bugs.debian.org/741407">a race condition in
 168 vmdebootstrap</a>, the build might fail without the patch to the
 169 kpartx call.</p>
 170
 171 <p>If you instead want to install using a Debian CD and the preseed
 172 method, boot a Debian Wheezy ISO and use this boot argument to load
 173 the preseed values:</p>
 174
 175 <pre>
 176 url=<a href="http://www.reinholdtsen.name/freedombox/preseed-jessie.dat">http://www.reinholdtsen.name/freedombox/preseed-jessie.dat</a>
 177 </pre>
 178
 179 <p>But note that due to <a href="https://bugs.debian.org/740673">a
 180 recently introduced bug in apt in Jessie</a>, the installer will
 181 currently hang while setting up APT sources.  Killing the
 182 '<tt>apt-cdrom ident</tt>' process when it hang a few times during the
 183 installation will get the installation going.  This affect all
 184 installations in Jessie, and I expect it will be fixed soon.</p>
 185
 186 Give it a go and let us know how it goes on the mailing list, and help
 187 us get the new release published. :) Please join us on
 188 <a href="irc://irc.debian.org:6667/%23freedombox">IRC (#freedombox on

 205       <div class="date">12th March 2014</div>
 206       <div class="body"><p>On larger sites, it is useful to use a dedicated storage server for
 207 storing user home directories and data.  The design for handling this
 208 in <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, is
 209 to update the automount rules in LDAP and let the automount daemon on
 210 the clients take care of the rest.  I was reminded about the need to
 211 document this better when one of the customers of
 212 <a href="http://www.slxdrift.no/">Skolelinux Drift AS</a>, where I am
 213 on the board of directors, asked about how to do this.  The steps to
 214 get this working are the following:</p>
 215
 216 <p><ol>
 217
 218 <li>Add new storage server in DNS.  I use nas-server.intern as the
 219 example host here.</li>
 220
 221 <li>Add automoun LDAP information about this server in LDAP, to allow
 222 all clients to automatically mount it on reqeust.</li>
 223
 224 <li>Add the relevant entries in tjener.intern:/etc/fstab, because
 225 tjener.intern do not use automount to avoid mounting loops.</li>
 226
 227 </ol></p>
 228
 229 <p>DNS entries are added in GOsa², and not described here.  Follow the
 230 <a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted">instructions
 231 in the manual</a> (Machine Management with GOsa² in section Getting
 232 started).</p>
 233
 234 <p>Ensure that the NFS export points on the server are exported to the
 235 relevant subnets or machines:</p>
 236
 237 <p><blockquote><pre>
 238 root@tjener:~# showmount -e nas-server
 239 Export list for nas-server:
 240 /storage         10.0.0.0/8
 241 root@tjener:~#
 242 </pre></blockquote></p>
 243
 244 <p>Here everything on the backbone network is granted access to the
 245 /storage export.  With NFSv3 it is slightly better to limit it to
 246 netgroup membership or single IP addresses to have some limits on the
 247 NFS access.</p>
 248
 249 <p>The next step is to update LDAP.  This can not be done using GOsa²,
 250 because it lack a module for automount.  Instead, use ldapvi and add
 251 the required LDAP objects using an editor.</p>
 252
 253 <p><blockquote><pre>
 254 ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
 255 </pre></blockquote></p>
 256
 257 <p>When the editor show up, add the following LDAP objects at the
 258 bottom of the document.  The "/&" part in the last LDAP object is a
 259 wild card matching everything the nas-server exports, removing the
 260 need to list individual mount points in LDAP.</p>
 261
 262 <p><blockquote><pre>
 263 add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no
 264 objectClass: automount
 265 cn: nas-server
 266 automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
 267
 268 add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
 269 objectClass: top
 270 objectClass: automountMap
 271 ou: auto.nas-server
 272
 273 add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
 274 objectClass: automount
 275 cn: /
 276 automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/&
 277 </pre></blockquote></p>
 278
 279 <p>The last step to remember is to mount the relevant mount points in
 280 tjener.intern by adding them to /etc/fstab, creating the mount
 281 directories using mkdir and running "mount -a" to mount them.</p>
 282
 283 <p>When this is done, your users should be able to access the files on
 284 the storage server directly by just visiting the
 285 /tjener/nas-server/storage/ directory using any application on any
 286 workstation, LTSP client or LTSP server.</p>

 300       <div class="date"> 7th March 2014</div>
 301       <div class="body"><p>For noen uker siden ble NXCs fri programvarelisenserte
 302 NOARK5-løsning
 303 <a href="http://www.nuug.no/aktiviteter/20140211-noark/">presentert hos
 304 NUUG</a> (video
 305 <a href="https://www.youtube.com/watch?v=JCb_dNS3MHQ">på youtube
 306 foreløbig</a>), og det fikk meg til å titte litt mer på NOARK5,
 307 standarden for arkivhåndtering i det offentlige Norge.  Jeg lurer på
 308 om denne kjernen kan være nyttig i et par av mine prosjekter, og for ett
 309 av dem er det mest aktuelt å lagre epost.  Jeg klarte ikke finne noen
 310 anbefaling om hvordan RFC 822-formattert epost (aka Internett-epost)
 311 burde lagres i NOARK5, selv om jeg vet at noen arkiver tar
 312 PDF-utskrift av eposten med sitt epostprogram og så arkiverer PDF-en
 313 (eller enda værre, tar papirutskrift og lagrer bildet av eposten som
 314 PDF i arkivet).</p>
 315
 316 <p>Det er ikke så mange formater som er akseptert av riksarkivet til
 317 langtidsoppbevaring av offentlige arkiver, og PDF og XML er de mest
 318 aktuelle i så måte.  Det slo meg at det måtte da finnes en eller annen
 319 egnet XML-representasjon og at det kanskje var enighet om hvilken som
 320 burde brukes, så jeg tok mot til meg og spurte
 321 <a href="http://samdok.com/">SAMDOK</a>, en gruppe tilknyttet
 322 arkivverket som ser ut til å jobbe med NOARK-samhandling, om de hadde
 323 noen anbefalinger:
 324
 325 <p><blockquote>
 326 <p>Hei.</p>
 327
 328 <p>Usikker på om dette er riktig forum å ta opp mitt spørsmål, men jeg
 329 lurer på om det er definert en anbefaling om hvordan RFC
 330 822-formatterte epost (aka vanlig Internet-epost) bør lages håndteres
 331 i NOARK5, slik at en bevarer all informasjon i eposten
 332 (f.eks. Received-linjer).  Finnes det en anbefalt XML-mapping ala den
 333 som beskrives på
 334 &lt;URL: <a href="https://www.informit.com/articles/article.aspx?p=32074">https://www.informit.com/articles/article.aspx?p=32074</a> &gt;?  Mitt
 335 mål er at det skal være mulig å lagre eposten i en NOARK5-kjerne og
 336 kunne få ut en identisk formattert kopi av opprinnelig epost ved
 337 behov.</p>
 338 </blockquote></p>
 339
 340 <p>Postmottaker hos SAMDOK mente spørsmålet heller burde stilles
 341 direkte til riksarkivet, og jeg fikk i dag svar derfra formulert av
 342 seniorrådgiver Geir Ivar Tungesvik:</p>
 343
 344 <p><blockquote>
 345 <p>Riksarkivet har ingen anbefalinger når det gjelder konvertering fra
 346 e-post til XML.  Det står arkivskaper fritt å eventuelt definere/bruke
 347 eget format.  Inklusive da - som det spørres om - et format der det er
 348 mulig å re-etablere e-post format ut fra XML-en.  XML (e-post)
 349 dokumenter må være referert i arkivstrukturen, og det må vedlegges et
 350 gyldig XML skjema (.xsd) for XML-filene. Arkivskaper står altså fritt
 351 til å gjøre hva de vil, bare det dokumenteres og det kan dannes et
 352 utrekk ved avlevering til depot.</p>
 353
 354 <p>De obligatoriske kravene i Noark 5 standarden må altså oppfylles -
 355 etter dialog med Riksarkivet i forbindelse med godkjenning. For
 356 offentlige arkiv er det særlig viktig med filene loependeJournal.xml
 357 og offentligJournal.xml. Private arkiv som vil forholde seg til Noark
 358 5 standarden er selvsagt frie til å bruke det som er relevant for dem
 359 av obligatoriske krav.</p>
 360 </blockquote></p>
 361
 362 <p>Det ser dermed ut for meg som om det er et lite behov for å
 363 standardisere XML-lagring av RFC-822-formatterte meldinger.  Noen som
 364 vet om god spesifikasjon i så måte?  I tillegg til den omtalt over,
 365 har jeg kommet over flere aktuelle beskrivelser (søk på "rfc 822
 366 xml", så finner du aktuelle alternativer).</p>

 509       <div class="date">22nd February 2014</div>
 510       <div class="body"><p>Many years ago, I wrote a GPL licensed version of the netgroup and
 511 innetgr tools, because I needed them in
 512 <a href="http://www.skolelinux.org/">Skolelinux</a>.  I called the project
 513 ng-utils, and it has served me well.  I placed the project under the
 514 <a href="http://www.hungry.com/">Hungry Programmer</a> umbrella, and it was maintained in our CVS
 515 repository.  But many years ago, the CVS repository was dropped (lost,
 516 not migrated to new hardware, not sure), and the project have lacked a
 517 proper home since then.</p>
 518
 519 <p>Last summer, I had a look at the package and made a new release
 520 fixing a irritating crash bug, but was unable to store the changes in
 521 a proper source control system.  I applied for a project on
 522 <a href="https://alioth.debian.org/">Alioth</a>, but did not have time
 523 to follow up on it.  Until today. :)</p>
 524
 525 <p>After many hours of cleaning and migration, the ng-utils project
 526 now have a new home, and a git repository with the highlight of the
 527 history of the project.  I published all release tarballs and imported
 528 them into the git repository.  As the project is really stable and not
 529 expected to gain new features any time soon, I decided to make a new
 530 release and call it 1.0.  Visit the new project home on
 531 <a href="https://alioth.debian.org/projects/ng-utils/">https://alioth.debian.org/projects/ng-utils/</a>
 532 if you want to check it out.  The new version is also uploaded into

 547       <div class="date"> 3rd February 2014</div>
 548       <div class="body"><p>A few days ago I decided to try to help the Hurd people to get
 549 their changes into sysvinit, to allow them to use the normal sysvinit
 550 boot system instead of their old one.  This follow up on the
 551 <a href="https://teythoon.cryptobitch.de//categories/gsoc.html">great
 552 Google Summer of Code work</a> done last summer by Justus Winter to
 553 get Debian on Hurd working more like Debian on Linux.  To get started,
 554 I downloaded a prebuilt hard disk image from
 555 <a href="http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz">http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz</a>,
 556 and started it using virt-manager.</p>
 557
 558 <p>The first think I had to do after logging in (root without any
 559 password) was to get the network operational.  I followed
 560 <a href="https://www.debian.org/ports/hurd/hurd-install">the
 561 instructions on the Debian GNU/Hurd ports page</a> and ran these
 562 commands as root to get the machine to accept a IP address from the
 563 kvm internal DHCP server:</p>
 564
 565 <p><blockquote><pre>
 566 settrans -fgap /dev/netdde /hurd/netdde
 567 kill $(ps -ef|awk '/[p]finet/ { print $2}')
 568 kill $(ps -ef|awk '/[d]evnode/ { print $2}')
 569 dhclient /dev/eth0
 570 </pre></blockquote></p>
 571
 572 <p>After this, the machine had internet connectivity, and I could
 573 upgrade it and install the sysvinit packages from experimental and
 574 enable it as the default boot system in Hurd.</p>
 575
 576 <p>But before I did that, I set a password on the root user, as ssh is
 577 running on the machine it for ssh login to work a password need to be
 578 set.  Also, note that a bug somewhere in openssh on Hurd block
 579 compression from working.  Remember to turn that off on the client
 580 side.</p>
 581
 582 <p>Run these commands as root to upgrade and test the new sysvinit
 583 stuff:</p>
 584
 585 <p><blockquote><pre>
 586 cat > /etc/apt/sources.list.d/experimental.list &lt;&lt;EOF
 587 deb http://http.debian.net/debian/ experimental main
 588 EOF
 589 apt-get update
 590 apt-get dist-upgrade
 591 apt-get install -t experimental initscripts sysv-rc sysvinit \
 592     sysvinit-core sysvinit-utils
 593 update-alternatives --config runsystem
 594 </pre></blockquote></p>
 595
 596 <p>To reboot after switching boot system, you have to use
 597 <tt>reboot-hurd</tt> instead of just <tt>reboot</tt>, as there is not
 598 yet a sysvinit process able to receive the signals from the normal
 599 'reboot' command.  After switching to sysvinit as the boot system,
 600 upgrading every package and rebooting, the network come up with DHCP
 601 after boot as it should, and the settrans/pkill hack mentioned at the
 602 start is no longer needed.  But for some strange reason, there are no
 603 longer any login prompt in the virtual console, so I logged in using
 604 ssh instead.
 605
 606 <p>Note that there are some race conditions in Hurd making the boot
 607 fail some times.  No idea what the cause is, but hope the Hurd porters
 608 figure it out.  At least Justus said on IRC (#debian-hurd on
 609 irc.debian.org) that they are aware of the problem.  A way to reduce
 610 the impact is to upgrade to the Hurd packages built by Justus by
 611 adding this repository to the machine:</p>
 612
 613 <p><blockquote><pre>
 614 cat > /etc/apt/sources.list.d/hurd-ci.list &lt;&lt;EOF
 615 deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
 616 EOF
 617 </pre></blockquote></p>
 618
 619 <p>At the moment the prebuilt virtual machine get some packages from
 620 http://ftp.debian-ports.org/debian, because some of the packages in
 621 unstable do not yet include the required patches that are lingering in
 622 BTS.  This is the completely list of "unofficial" packages installed:</p>
 623
 624 <p><blockquote><pre>
 625 # aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))'

 642 </pre></blockquote></p>
 643
 644 <p>All in all, testing hurd has been an interesting experience. :)
 645 X.org did not work out of the box and I never took the time to follow
 646 the porters instructions to fix it.  This time I was interested in the
 647 command line stuff.<p>

 661       <div class="date">29th January 2014</div>
 662       <div class="body"><p>Bitcoin is a incredible use of peer to peer communication and
 663 encryption, allowing direct and immediate money transfer without any
 664 central control.  It is sometimes claimed to be ideal for illegal
 665 activity, which I believe is quite a long way from the truth.  At least
 666 I would not conduct illegal money transfers using a system where the
 667 details of every transaction are kept forever.  This point is
 668 investigated in
 669 <a href="https://www.usenix.org/publications/login">USENIX ;login:</a>
 670 from December 2013, in the article
 671 "<a href="https://www.usenix.org/system/files/login/articles/03_meiklejohn-online.pdf">A
 672 Fistful of Bitcoins - Characterizing Payments Among Men with No
 673 Names</a>" by Sarah Meiklejohn, Marjori Pomarole,Grant Jordan, Kirill
 674 Levchenko, Damon McCoy, Geoffrey M. Voelker, and Stefan Savage.  They
 675 analyse the transaction log in the Bitcoin system, using it to find
 676 addresses belong to individuals and organisations and follow the flow
 677 of money from both Bitcoin theft and trades on Silk Road to where the
 678 money end up.  This is how they wrap up their article:</p>
 679
 680 <p><blockquote>
 681 <p>"To demonstrate the usefulness of this type of analysis, we turned
 682 our attention to criminal activity. In the Bitcoin economy, criminal
 683 activity can appear in a number of forms, such as dealing drugs on
 684 Silk Road or simply stealing someone else’s bitcoins. We followed the
 685 flow of bitcoins out of Silk Road (in particular, from one notorious
 686 address) and from a number of highly publicized thefts to see whether
 687 we could track the bitcoins to known services. Although some of the
 688 thieves attempted to use sophisticated mixing techniques (or possibly
 689 mix services) to obscure the flow of bitcoins, for the most part
 690 tracking the bitcoins was quite straightforward, and we ultimately saw
 691 large quantities of bitcoins flow to a variety of exchanges directly
 692 from the point of theft (or the withdrawal from Silk Road).</p>
 693
 694 <p>As acknowledged above, following stolen bitcoins to the point at
 695 which they are deposited into an exchange does not in itself identify
 696 the thief; however, it does enable further de-anonymization in the
 697 case in which certain agencies can determine (through, for example,
 698 subpoena power) the real-world owner of the account into which the
 699 stolen bitcoins were deposited.  Because such exchanges seem to serve
 700 as chokepoints into and out of the Bitcoin economy (i.e., there are
 701 few alternative ways to cash out), we conclude that using Bitcoin for
 702 money laundering or other illicit purposes does not (at least at
 703 present) seem to be particularly attractive."</p>
 704 </blockquote><p>
 705
 706 <p>These researches are not the first to analyse the Bitcoin
 707 transaction log.  The 2011 paper
 708 "<a href="http://arxiv.org/abs/1107.4524">An Analysis of Anonymity in
 709 the Bitcoin System</A>" by Fergal Reid and Martin Harrigan is
 710 summarized like this:</p>
 711
 712 <p><blockquote>
 713 "Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a
 714 complicated issue. Within the system, users are identified by
 715 public-keys only. An attacker wishing to de-anonymize its users will
 716 attempt to construct the one-to-many mapping between users and
 717 public-keys and associate information external to the system with the
 718 users. Bitcoin tries to prevent this attack by storing the mapping of
 719 a user to his or her public-keys on that user's node only and by
 720 allowing each user to generate as many public-keys as required. In
 721 this chapter we consider the topological structure of two networks
 722 derived from Bitcoin's public transaction history. We show that the
 723 two networks have a non-trivial topological structure, provide
 724 complementary views of the Bitcoin system and have implications for
 725 anonymity. We combine these structures with external information and
 726 techniques such as context discovery and flow analysis to investigate
 727 an alleged theft of Bitcoins, which, at the time of the theft, had a
 728 market value of approximately half a million U.S. dollars."
 729 </blockquote></p>
 730
 731 <p>I hope these references can help kill the urban myth that Bitcoin
 732 is anonymous.  It isn't really a good fit for illegal activites.  Use
 733 cash if you need to stay anonymous, at least until regular DNA
 734 sampling of notes and coins become the norm. :)</p>

 758 <a href="https://scan.coverity.com/">check of free software projects as
 759 a community service</a>, and many hundred free software projects are
 760 already checked.  A few days ago I decided to have a closer look at
 761 the Coverity system, and discovered that the
 762 <a href="http://www.gnu.org/software/gnash/">gnash</a> and
 763 <a href="http://sourceforge.net/projects/ipmitool/">ipmitool</a>
 764 projects I am involved with was already registered.  But these are
 765 fairly big, and I would also like to have a small and easy project to
 766 check, and decided to <a href="http://scan.coverity.com/projects/1179">request
 767 checking of the chrpath project</a>.  It was
 768 added to the checker and discovered seven potential defects.  Six of
 769 these were real, mostly resource "leak" when the program detected an
 770 error.  Nothing serious, as the resources would be released a fraction
 771 of a second later when the program exited because of the error, but it
 772 is nice to do it right in case the source of the program some time in
 773 the future end up in a library.  Having fixed all defects and added
 774 <a href="https://lists.alioth.debian.org/mailman/listinfo/chrpath-devel">a
 775 mailing list for the chrpath developers</a>, I decided it was time to
 776 publish a new release.  These are the release notes:</p>
 777
 778 <p>New in 0.16 released 2014-01-14:</p>
 779
 780 <ul>
 781
 782   <li>Fixed all minor bugs discovered by Coverity.</li>
 783   <li>Updated config.sub and config.guess from the GNU project.</li>
 784   <li>Mention new project mailing list in the documentation.</li>
 785
 786 </ul>
 787
 788 <p>You can
 789 <a href="https://alioth.debian.org/frs/?group_id=31052">download the
 790 new version 0.16 from alioth</a>.  Please let us know via the Alioth
 791 project if something is wrong with the new release.  The test suite
 792 did not discover any old errors, so if you find a new one, please also
 793 include a test suite check.</p>
