  24       <div class="date">11th April 2014</div>
  25       <div class="body"><p>For 12 år siden, skrev jeg et lite notat om
  26 <a href="http://i18n.skolelinux.no/localekoder.txt">bruk av språkkoder
  27 i Norge</a>.  Jeg ble nettopp minnet på dette da jeg fikk spørsmål om
  28 notatet fortsatt var aktuelt, og tenkte det var greit å repetere hva
  29 som fortsatt gjelder.  Det jeg skrev da er fortsatt like aktuelt.</p>
  30
  31 <p>Når en velger språk i programmer på unix, så velger en blant mange
  32 språkkode.  For språk i Norge anbefales følgende språkkoder (anbefalt
  33 locale i parantes):</p>
  34
  35 <p><dl>
  36 <dt>nb (nb_NO)</dt><dd>Bokmål i Norge</dd>
  37 <dt>nn (nn_NO)</dt><dd>Nynorsk i Norge</dd>
  38 <dt>se (se_NO)</dt><dd>Nordsamisk i Norge</dd>
  39 </dl></p>
  40
  41 <p>Alle programmer som bruker andre koder bør endres.</p>
  42
  43 <p>Språkkoden bør brukes når .po-filer navngis og installeres.  Dette
  44 er ikke det samme som locale-koden.  For Norsk Bokmål, så bør filene
  45 være navngitt nb.po, mens locale (LANG) bør være nb_NO.</p>
  46
  47 <p>Hvis vi ikke får standardisert de kodene i alle programmene med
  48 norske oversettelser, så er det umulig å gi LANG-variablen ett innhold
  49 som fungerer for alle programmer.</p>
  50
  51 <p>Språkkodene er de offisielle kodene fra ISO 639, og bruken av dem i
  52 forbindelse med POSIX localer er standardisert i RFC 3066 og ISO
  53 15897.  Denne anbefalingen er i tråd med de angitte standardene.</p>
  54
  55 <p>Følgende koder er eller har vært i bruk som locale-verdier for
  56 "norske" språk.  Disse bør unngås, og erstattes når de oppdages:</p>
  57
  58 <p><table>
  59 <tr><td>norwegian</td><td>-> nb_NO</td></tr>
  60 <tr><td>bokmål   </td><td>-> nb_NO</td></tr>
  61 <tr><td>bokmal   </td><td>-> nb_NO</td></tr>
  62 <tr><td>nynorsk  </td><td>-> nn_NO</td></tr>
  63 <tr><td>no       </td><td>-> nb_NO</td></tr>
  64 <tr><td>no_NO    </td><td>-> nb_NO</td></tr>
  65 <tr><td>no_NY    </td><td>-> nn_NO</td></tr>
  66 <tr><td>sme_NO   </td><td>-> se_NO</td></tr>
  67 </table></p>
  68
  69 <p>Merk at når det gjelder de samiske språkene, at se_NO i praksis
  70 henviser til nordsamisk i Norge, mens f.eks.  smj_NO henviser til
  71 lulesamisk.  Dette notatet er dog ikke ment å gi råd rundt samiske
  72 språkkoder, der gjør
  73 <a href="http://www.divvun.no/">Divvun-prosjektet</a> en bedre
  74 jobb.</p>

 113       <div class="date"> 9th April 2014</div>
 114       <div class="body"><p>For a while now, I have been looking for a sensible offsite backup
 115 solution for use at home.  My requirements are simple, it must be
 116 cheap and locally encrypted (in other words, I keep the encryption
 117 keys, the storage provider do not have access to my private files).
 118 One idea me and my friends had many years ago, before the cloud
 119 storage providers showed up, was to use Google mail as storage,
 120 writing a Linux block device storing blocks as emails in the mail
 121 service provided by Google, and thus get heaps of free space.  On top
 122 of this one can add encryption, RAID and volume management to have
 123 lots of (fairly slow, I admit that) cheap and encrypted storage.  But
 124 I never found time to implement such system.  But the last few weeks I
 125 have looked at a system called
 126 <a href="https://bitbucket.org/nikratio/s3ql/">S3QL</a>, a locally
 127 mounted network backed file system with the features I need.</p>
 128
 129 <p>S3QL is a fuse file system with a local cache and cloud storage,
 130 handling several different storage providers, any with Amazon S3,
 131 Google Drive or OpenStack API.  There are heaps of such storage
 132 providers.  S3QL can also use a local directory as storage, which
 133 combined with sshfs allow for file storage on any ssh server.  S3QL
 134 include support for encryption, compression, de-duplication, snapshots
 135 and immutable file systems, allowing me to mount the remote storage as
 136 a local mount point, look at and use the files as if they were local,
 137 while the content is stored in the cloud as well.  This allow me to
 138 have a backup that should survive fire.  The file system can not be
 139 shared between several machines at the same time, as only one can
 140 mount it at the time, but any machine with the encryption key and
 141 access to the storage service can mount it if it is unmounted.</p>
 142
 143 <p>It is simple to use.  I'm using it on Debian Wheezy, where the
 144 package is included already.  So to get started, run <tt>apt-get
 145 install s3ql</tt>.  Next, pick a storage provider.  I ended up picking
 146 Greenqloud, after reading their nice recipe on
 147 <a href="https://greenqloud.zendesk.com/entries/44611757-How-To-Use-S3QL-to-mount-a-StorageQloud-bucket-on-Debian-Wheezy">how
 148 to use S3QL with their Amazon S3 service</a>, because I trust the laws
 149 in Iceland more than those in USA when it come to keeping my personal
 150 data safe and private, and thus would rather spend money on a company
 151 in Iceland.  Another nice recipe is available from the article
 152 <a href="http://www.admin-magazine.com/HPC/Articles/HPC-Cloud-Storage">S3QL
 153 Filesystem for HPC Storage</a> by Jeff Layton in the HPC section of
 154 Admin magazine.  When the provider is picked, figure out how to get
 155 the API key needed to connect to the storage API.  With Greencloud,
 156 the key did not show up until I had added payment details to my
 157 account.</p>
 158
 159 <p>Armed with the API access details, it is time to create the file
 160 system.  First, create a new bucket in the cloud.  This bucket is the
 161 file system storage area.  I picked a bucket name reflecting the
 162 machine that was going to store data there, but any name will do.
 163 I'll refer to it as <tt>bucket-name</tt> below.  In addition, one need
 164 the API login and password, and a locally created password.  Store it
 165 all in ~root/.s3ql/authinfo2 like this:
 166
 167 <p><blockquote><pre>
 168 [s3c]
 169 storage-url: s3c://s.greenqloud.com:443/bucket-name
 170 backend-login: API-login
 171 backend-password: API-password
 172 fs-passphrase: local-password
 173 </pre></blockquote></p>
 174
 175 <p>I create my local passphrase using <tt>pwget 50</tt> or similar,
 176 but any sensible way to create a fairly random password should do it.
 177 Armed with these details, it is now time to run mkfs, entering the API
 178 details and password to create it:</p>
 179
 180 <p><blockquote><pre>
 181 # mkdir -m 700 /var/lib/s3ql-cache
 182 # mkfs.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
 183   --ssl s3c://s.greenqloud.com:443/bucket-name
 184 Enter backend login:
 185 Enter backend password:
 186 Before using S3QL, make sure to read the user's guide, especially
 187 the 'Important Rules to Avoid Loosing Data' section.
 188 Enter encryption password:
 189 Confirm encryption password:

 205 <p>The next step is mounting the file system to make the storage available.

 225 #
 226 </pre></blockquote></p>
 227
 228 <p>The file system is now ready for use.  I use rsync to store my
 229 backups in it, and as the metadata used by rsync is downloaded at
 230 mount time, no network traffic (and storage cost) is triggered by
 231 running rsync.  To unmount, one should not use the normal umount
 232 command, as this will not flush the cache to the cloud storage, but
 233 instead running the umount.s3ql command like this:
 234
 235 <p><blockquote><pre>
 236 # umount.s3ql /s3ql
 237 #
 238 </pre></blockquote></p>
 239
 240 <p>There is a fsck command available to check the file system and
 241 correct any problems detected.  This can be used if the local server
 242 crashes while the file system is mounted, to reset the "already
 243 mounted" flag.  This is what it look like when processing a working
 244 file system:</p>
 245

 292 <p>Thanks to the cache, working on files that fit in the cache is very
 293 quick, about the same speed as local file access.  Uploading large
 294 amount of data is to me limited by the bandwidth out of and into my
 295 house.  Uploading 685 MiB with a 100 MiB cache gave me 305 kiB/s,
 296 which is very close to my upload speed, and downloading the same
 297 Debian installation ISO gave me 610 kiB/s, close to my download speed.
 298 Both were measured using <tt>dd</tt>.  So for me, the bottleneck is my
 299 network, not the file system code.  I do not know what a good cache
 300 size would be, but suspect that the cache should e larger than your
 301 working set.</p>
 302
 303 <p>I mentioned that only one machine can mount the file system at the
 304 time.  If another machine try, it is told that the file system is
 305 busy:</p>
 306
 307 <p><blockquote><pre>
 308 # mount.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
 309   --ssl --allow-root s3c://s.greenqloud.com:443/bucket-name /s3ql
 310 Using 8 upload threads.
 311 Backend reports that fs is still mounted elsewhere, aborting.
 312 #
 313 </pre></blockquote></p>
 314
 315 <p>The file content is uploaded when the cache is full, while the
 316 metadata is uploaded once every 24 hour by default.  To ensure the
 317 file system content is flushed to the cloud, one can either umount the
 318 file system, or ask S3QL to flush the cache and metadata using
 319 s3qlctrl:
 320
 321 <p><blockquote><pre>
 322 # s3qlctrl upload-meta /s3ql
 323 # s3qlctrl flushcache /s3ql
 324 #
 325 </pre></blockquote></p>
 326
 327 <p>If you are curious about how much space your data uses in the
 328 cloud, and how much compression and deduplication cut down on the
 329 storage usage, you can use s3qlstat on the mounted file system to get
 330 a report:</p>
 331
 332 <p><blockquote><pre>
 333 # s3qlstat /s3ql
 334 Directory entries:    9141
 335 Inodes:               9143
 336 Data blocks:          8851
 337 Total data size:      22049.38 MB
 338 After de-duplication: 21955.46 MB (99.57% of total)
 339 After compression:    21877.28 MB (99.22% of total, 99.64% of de-duplicated)
 340 Database size:        2.39 MB (uncompressed)
 341 (some values do not take into account not-yet-uploaded dirty blocks in cache)
 342 #
 343 </pre></blockquote></p>
 344
 345 <p>I mentioned earlier that there are several possible suppliers of
 346 storage.  I did not try to locate them all, but am aware of at least
 347 <a href="https://www.greenqloud.com/">Greenqloud</a>,
 348 <a href="http://drive.google.com/">Google Drive</a>,
 349 <a href="http://aws.amazon.com/s3/">Amazon S3 web serivces</a>,
 350 <a href="http://www.rackspace.com/">Rackspace</a> and
 351 <a href="http://crowncloud.net/">Crowncloud</A>.  The latter even
 352 accept payment in Bitcoin.  Pick one that suit your need.  Some of
 353 them provide several GiB of free storage, but the prize models are
 354 quite different and you will have to figure out what suits you
 355 best.</p>
 356
 357 <p>While researching this blog post, I had a look at research papers
 358 and posters discussing the S3QL file system.  There are several, which
 359 told me that the file system is getting a critical check by the
 360 science community and increased my confidence in using it.  One nice
 361 poster is titled
 362 "<a href="http://www.lanl.gov/orgs/adtsc/publications/science_highlights_2013/docs/pg68_69.pdf">An
 363 Innovative Parallel Cloud Storage System using OpenStack’s SwiftObject
 364 Store and Transformative Parallel I/O Approach</a>" by Hsing-Bung
 365 Chen, Benjamin McClelland, David Sherrill, Alfred Torrez, Parks Fields
 366 and Pamela Smith.  Please  have a look.</p>
 367
 368 <p>Given my problems with different file systems earlier, I decided to
 369 check out the mounted S3QL file system to see if it would be usable as
 370 a home directory (in other word, that it provided POSIX semantics when
 371 it come to locking and umask handling etc).  Running
 372 <a href="http://people.skolelinux.org/pere/blog/Testing_if_a_file_system_can_be_used_for_home_directories___.html">my
 373 test code to check file system semantics</a>, I was happy to discover that
 374 no error was found.  So the file system can be used for home
 375 directories, if one chooses to do so.</p>
 376
 377 <p>If you do not want a locally file system, and want something that
 378 work without the Linux fuse file system, I would like to mention the
 379 <a href="http://www.tarsnap.com/">Tarsnap service</a>, which also
 380 provide locally encrypted backup using a command line client.  It have
 381 a nicer access control system, where one can split out read and write
 382 access, allowing some systems to write to the backup and others to
 383 only read from it.</p>

 488       <div class="date"> 1st April 2014</div>
 489       <div class="body"><p>Microsoft have announced that Windows XP reaches its end of life
 490 2014-04-08, in 7 days.  But there are heaps of machines still running
 491 Windows XP, and depending on Windows XP to run their applications, and
 492 upgrading will be expensive, both when it comes to money and when it
 493 comes to the amount of effort needed to migrate from Windows XP to a
 494 new operating system.  Some obvious options (buy new a Windows
 495 machine, buy a MacOSX machine, install Linux on the existing machine)
 496 are already well known and covered elsewhere.  Most of them involve
 497 leaving the user applications installed on Windows XP behind and
 498 trying out replacements or updated versions. In this blog post I want
 499 to mention one strange bird that allow people to keep the hardware and
 500 the existing Windows XP applications and run them on a free software
 501 operating system that is Windows XP compatible.</p>
 502
 503 <p><a href="http://www.reactos.org/">ReactOS</a> is a free software
 504 operating system (GNU GPL licensed) working on providing a operating
 505 system that is binary compatible with Windows, able to run windows
 506 programs directly and to use Windows drivers for hardware directly.
 507 The project goal is for Windows user to keep their existing machines,
 508 drivers and software, and gain the advantages from user a operating
 509 system without usage limitations caused by non-free licensing.  It is
 510 a Windows clone running directly on the hardware, so quite different
 511 from the approach taken by <a href="http://www.winehq.org/">the Wine
 512 project</a>, which make it possible to run Windows binaries on
 513 Linux.</p>
 514
 515 <p>The ReactOS project share code with the Wine project, so most
 516 shared libraries available on Windows are already implemented already.
 517 There is also a software manager like the one we are used to on Linux,
 518 allowing the user to install free software applications with a simple
 519 click directly from the Internet.  Check out the
 520 <a href="http://www.reactos.org/screenshots">screen shots on the
 521 project web site</a> for an idea what it look like (it looks just like
 522 Windows before metro).</p>
 523
 524 <p>I do not use ReactOS myself, preferring Linux and Unix like
 525 operating systems.  I've tested it, and it work fine in a virt-manager
 526 virtual machine.  The browser, minesweeper, notepad etc is working
 527 fine as far as I can tell.  Unfortunately, my main test application
 528 is the software included on a CD with the Lego Mindstorms NXT, which
 529 seem to install just fine from CD but fail to leave any binaries on
 530 the disk after the installation.  So no luck with that test software.
 531 No idea why, but hope someone else figure out and fix the problem.
 532 I've tried the ReactOS Live ISO on a physical machine, and it seemed
 533 to work just fine.  If you like Windows and want to keep running your
 534 old Windows binaries, check it out by
 535 <a href="http://www.reactos.org/download">downloading</a> the
 536 installation CD, the live CD or the preinstalled virtual machine
 537 image.</p>

 551       <div class="date">30th March 2014</div>
 552       <div class="body"><p><a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>
 553 keep gaining new users.  Some weeks ago, a person showed up on IRC,
 554 <a href="irc://irc.debian.org/#debian-edu">#debian-edu</a>, with a
 555 wish to contribute, and I managed to get a interview with this great
 556 contributor Roger Marsal to learn more about his background.</p>
 557
 558 <p><strong>Who are you, and how do you spend your days?</strong></p>
 559
 560 <p>My name is Roger Marsal, I'm 27 years old (1986 generation) and I
 561 live in Barcelona, Spain. I've got a strong business background and I
 562 work as a patrimony manager and as a real estate agent.  Additionally,
 563 I've co-founded a British based tech company that is nowadays on the
 564 last development phase of a new social networking concept.</p>
 565
 566 <p>I'm a Linux enthusiast that started its journey with Ubuntu four years
 567 ago and have recently switched to Debian seeking rock solid stability
 568 and as a necessary step to gain expertise.</p>
 569
 570 <p>In a nutshell, I spend my days working and learning as much as I
 571 can to face both my job, entrepreneur project and feed my Linux
 572 hunger.</p>
 573
 574 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
 575 project?</strong></p>
 576
 577 <p>I discovered the <a href="http://www.ltsp.org/">LTSP</a> advantages
 578 with "Ubuntu 12.04 alternate install" and after a year of use I
 579 started looking for an alternative.  Even though I highly value and
 580 respect the Ubuntu project, I thought it was necessary for me to
 581 change to a more robust and stable alternative.  As far as I was using
 582 Debian on my personal laptop I thought it would be fine to install
 583 Debian and configure an LTSP server myself.  Surprised, I discovered
 584 that the Debian project also supported a kind of Edubuntu equivalent,
 585 and after having some pain I obtained a Debian Edu network up and
 586 running.  I just loved it.</p>
 587
 588 <p><strong>What do you see as the advantages of Skolelinux / Debian
 589 Edu?</strong></p>
 590
 591 <p>I found a main advantage in that, once you know "the tips and
 592 tricks", a new installation just works out of the box. It's the most
 593 complete alternative I've found to create an LTSP network. All the
 594 other distributions seems to be made of plastic, Debian Edu seems to
 595 be made of steel.</p>
 596
 597 <p><strong>What do you see as the disadvantages of Skolelinux / Debian
 598 Edu?</strong></p>
 599
 600 <p>I found two main disadvantages.</p>
 601
 602 <p>I'm not an expert but I've got notions and I had to spent a considerable
 603 amount of time trying to bring up a standard network topology. I'm quite
 604 stubborn and I just worked until I did but I'm sure many people with few
 605 resources (not big schools, but academies for example) would have switched
 606 or dropped.</p>
 607
 608 <p>It's amazing how such a complex system like Debian Edu has achieved
 609 this out-of-the-box state. Even though tweaking without breaking gets
 610 more difficult, as more factors have to be considered. This can
 611 discourage many people too.</p>
 612
 613 <p><strong>Which free software do you use daily?</strong></p>
 614
 615 <p>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
 616 Virtualbox.</p>
 617
 618
 619 <p><strong>Which strategy do you believe is the right one to use to
 620 get schools to use free software?</strong></p>
 621
 622 <p>I don't think there is a need for a particular strategy. The free
 623 attribute in both "freedom" and "no price" meanings is what will
 624 really bring free software to schools. In my experience I can think of
 625 the <a href="http://www.r-project.org/">"R" statistical language</a>; a
 626 few years a ago was an extremely nerd tool for university people.
 627 Today it's being increasingly used to teach statistics at many
 628 different level of studies.  I believe free and open software will
 629 increasingly gain popularity, but I'm sure schools will be one of the
 630 first scenarios where this will happen.</p>

 653 Jeg har sett dokumentaren, og jeg anbefaler enhver å se den selv.  Som
 654 oppvarming mens vi venter anbefaler jeg Bjørn Stærks kronikk i
 655 Aftenposten fra i går,
 656 <a href="http://www.aftenposten.no/meninger/kronikker/Autoritar-gjokunge-7514915.html">Autoritær
 657 gjøkunge</a>, der han gir en grei skisse av hvor ille det står til med
 658 retten til privatliv og beskyttelsen av demokrati i Norge og resten
 659 verden, og helt riktig slår fast at det er vi i databransjen som
 660 sitter med nøkkelen til å gjøre noe med dette.  Jeg har involvert meg
 661 i prosjektene <a href="http://www.dugnadsnett.no/">dugnadsnett.no</a>
 662 og <a href="https://wiki.debian.org/FreedomBox">FreedomBox</a> for å
 663 forsøke å gjøre litt selv for å bedre situasjonen, men det er mye
 664 hardt arbeid fra mange flere enn meg som gjenstår før vi kan sies å ha
 665 gjenopprettet balansen.</p>
 666
 667 <p>Jeg regner med at nettutgaven dukker opp på
 668 <a href="http://tv.nrk.no/program/koid75005313/tema-dine-digitale-spor-datalagringsdirektivet">NRKs
 669 side om filmen om datalagringsdirektivet</a> om fem dager.  Hold et

 684       <div class="date">25th March 2014</div>
 685       <div class="body"><p>Did you ever need to store logs or other files in a way that would
 686 allow it to be used as evidence in court, and needed a way to
 687 demonstrate without reasonable doubt that the file had not been
 688 changed since it was created?  Or, did you ever need to document that
 689 a given document was received at some point in time, like some
 690 archived document or the answer to an exam, and not changed after it
 691 was received?  The problem in these settings is to remove the need to
 692 trust yourself and your computers, while still being able to prove
 693 that a file is the same as it was at some given time in the past.</p>
 694
 695 <p>A solution to these problems is to have a trusted third party
 696 "stamp" the document and verify that at some given time the document
 697 looked a given way.  Such
 698 <a href="https://en.wikipedia.org/wiki/Notarius">notarius</a> service
 699 have been around for thousands of years, and its digital equivalent is
 700 called a
 701 <a href="http://en.wikipedia.org/wiki/Trusted_timestamping">trusted
 702 timestamping service</a>.  <a href="http://www.ietf.org/">The Internet
 703 Engineering Task Force</a> standardised how such service could work a
 704 few years ago as <a href="http://tools.ietf.org/html/rfc3161">RFC
 705 3161</a>.  The mechanism is simple.  Create a hash of the file in
 706 question, send it to a trusted third party which add a time stamp to
 707 the hash and sign the result with its private key, and send back the
 708 signed hash + timestamp.  Both email, FTP and HTTP can be used to
 709 request such signature, depending on what is provided by the service
 710 used. Anyone with the document and the signature can then verify that
 711 the document matches the signature by creating their own hash and
 712 checking the signature using the trusted third party public key.
 713 There are several commercial services around providing such
 714 timestamping.  A quick search for
 715 "<a href="https://duckduckgo.com/?q=rfc+3161+service">rfc 3161
 716 service</a>" pointed me to at least
 717 <a href="https://www.digistamp.com/technical/how-a-digital-time-stamp-works/">DigiStamp</a>,
 718 <a href="http://www.quovadisglobal.co.uk/CertificateServices/SigningServices/TimeStamp.aspx">Quo
 719 Vadis</a>,
 720 <a href="https://www.globalsign.com/timestamp-service/">Global Sign</a>
 721 and <a href="http://www.globaltrustfinder.com/TSADefault.aspx">Global
 722 Trust Finder</a>.  The system work as long as the private key of the
 723 trusted third party is not compromised.</p>
 724
 725 <p>But as far as I can tell, there are very few public trusted
 726 timestamp services available for everyone.  I've been looking for one
 727 for a while now. But yesterday I found one over at
 728 <a href="https://www.pki.dfn.de/zeitstempeldienst/">Deutches
 729 Forschungsnetz</a> mentioned in
 730 <a href="http://www.d-mueller.de/blog/dealing-with-trusted-timestamps-in-php-rfc-3161/">a
 731 blog by David Müller</a>.  I then found
 732 <a href="http://www.rz.uni-greifswald.de/support/dfn-pki-zertifikate/zeitstempeldienst.html">a
 733 good recipe on how to use the service</a> over at the University of
 734 Greifswald.</p>
 735
 736 <p><a href="http://www.openssl.org/">The OpenSSL library</a> contain
 737 both server and tools to use and set up your own signing service.  See
 738 the ts(1SSL), tsget(1SSL) manual pages for more details.  The
 739 following shell script demonstrate how to extract a signed timestamp
 740 for any file on the disk in a Debian environment:</p>
 741
 742 <p><blockquote><pre>
 743 #!/bin/sh
 744 set -e
 745 url="http://zeitstempel.dfn.de"
 746 caurl="https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt"
 747 reqfile=$(mktemp -t tmp.XXXXXXXXXX.tsq)
 748 resfile=$(mktemp -t tmp.XXXXXXXXXX.tsr)
 749 cafile=chain.txt
 750 if [ ! -f $cafile ] ; then
 751     wget -O $cafile "$caurl"
 752 fi
 753 openssl ts -query -data "$1" -cert | tee "$reqfile" \
 754     | /usr/lib/ssl/misc/tsget -h "$url" -o "$resfile"
 755 openssl ts -reply -in "$resfile" -text 1>&2
 756 openssl ts -verify -data "$1" -in "$resfile" -CAfile "$cafile" 1>&2
 757 base64 < "$resfile"
 758 rm "$reqfile" "$resfile"
 759 </pre></blockquote></p>
 760
 761 <p>The argument to the script is the file to timestamp, and the output
 762 is a base64 encoded version of the signature to STDOUT and details
 763 about the signature to STDERR.  Note that due to
 764 <a href="http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=742553">a bug
 765 in the tsget script</a>, you might need to modify the included script
 766 and remove the last line.  Or just write your own HTTP uploader using
 767 curl. :) Now you too can prove and verify that files have not been
 768 changed.</p>
 769
 770 <p>But the Internet need more public trusted timestamp services.
 771 Perhaps something for <a href="http://www.uninett.no/">Uninett</a> or
 772 my work place the <a href="http://www.uio.no/">University of Oslo</a>
 773 to set up?</p>

 801 and program
 802 <a href="http://bblank.thinkmo.de/blog/new-software-python-dvdvideo">python-dvdvideo</a>
 803 written by Bastian Blank.  It is
 804 <a href="http://packages.qa.debian.org/p/python-dvdvideo.html">in Debian
 805 already</a> and the binary package name is python3-dvdvideo. Instead
 806 of trying to read every block from the DVD, it parses the file
 807 structure and figure out which block on the DVD is actually in used,
 808 and only read those blocks from the DVD.  This work surprisingly well,
 809 and I have been able to almost backup my entire DVD collection using
 810 this method.</p>
 811
 812 <p>So far, python-dvdvideo have failed on between 10 and
 813 20 DVDs, which is a small fraction of my collection.  The most common
 814 problem is
 815 <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720831">DVDs
 816 using UTF-16 instead of UTF-8 characters</a>, which according to
 817 Bastian is against the DVD specification (and seem to cause some
 818 players to fail too).  A rarer problem is what seem to be inconsistent
 819 DVD structures, as the python library
 820 <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079">claim
 821 there is a overlap between objects</a>.  An equally rare problem claim
 822 <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741878">some
 823 value is out of range</a>.  No idea what is going on there.  I wish I
 824 knew enough about the DVD format to fix these, to ensure my movie
 825 collection will stay with me in the future.</p>
 826
 827 <p>So, if you need to keep your DVDs safe, back them up using
 828 python-dvdvideo. :)</p>

 843       <div class="body"><p>Det offentlige Norge har mye kunnskap og informasjon.  Men hvordan
 844 kan en få tilgang til den på en enkel måte?  Takket være et lite
 845 knippe lover og tilhørende forskrifter, blant annet
 846 <a href="http://lovdata.no/dokument/NL/lov/2006-05-19-16">offentlighetsloven</a>,
 847 <a href="http://lovdata.no/dokument/NL/lov/2003-05-09-31">miljøinformasjonsloven</a>
 848 og
 849 <a href="http://lovdata.no/dokument/NL/lov/1967-02-10/">forvaltningsloven</a>
 850 har en rett til å spørre det offentlige og få svar.  Men det finnes
 851 intet offentlig arkiv over hva andre har spurt om, og dermed risikerer en
 852 å måtte forstyrre myndighetene gang på gang for å få tak i samme
 853 informasjonen på nytt.  <a href="http://www.mysociety.org/">Britiske
 854 mySociety</a> har laget tjenesten
 855 <a href="http://www.whatdotheyknow.com/">WhatDoTheyKnow</a> som gjør
 856 noe med dette.  I Storbritannia blir WhatdoTheyKnow brukt i
 857 <a href="http://www.mysociety.org/2011/07/01/whatdotheyknows-share-of-central-government-foi-requests-q2-2011/">ca
 858 15% av alle innsynsforespørsler mot sentraladministrasjonen</a>.
 859 Prosjektet heter <a href="http://www.alaveteli.org/">Alaveteli</A>, og
 860 er takk i bruk en rekke steder etter at løsningen ble generalisert og
 861 gjort mulig å oversette.  Den hjelper borgerne med å be om innsyn,
 862 rådgir ved purringer og klager og lar alle se hvilke henvendelser som
 863 er sendt til det offentlige og hvilke svar som er kommet inn, i et
 864 søkpart arkiv.  Her i Norge holder vi i foreningen NUUG på å få opp en
 865 norsk utgave av Alaveteli, og her trenger vi din hjelp med
 866 oversettelsen.</p>
 867
 868 <p>Så langt er 76 % av Alaveteli oversatt til norsk bokmål, men vi
 869 skulle gjerne vært oppe i 100 % før lansering.  Oversettelsen gjøres
 870 på <a href="https://www.transifex.com/projects/p/alaveteli/">Transifex,
 871 der enhver som registrerer seg</a> og ber om tilgang til
 872 bokmålsoversettelsen får bidra.  Vi har satt opp en test av tjenesten
 873 (som ikke sender epost til det offentlige, kun til oss som holder på å
 874 sette opp tjenesten) på maskinen
 875 <a href="http://alaveteli-dev.nuug.no/">alaveteli-dev.nuug.no</a>, der
 876 en kan se hvordan de oversatte meldingen blir seende ut på nettsiden.
 877 Når tjenesten lanseres vil den hete
 878 <a href="https://www.mimesbrønn.no/">Mimes brønn</a>, etter
 879 visdomskilden som Odin måtte gi øyet sitt for å få drikke i.  Den
 880 nettsiden er er ennå ikke klar til bruk.</p>
 881
 882 <p>Hvis noen vil oversette til nynorsk også, så skal vi finne ut
 883 hvordan vi lager en flerspråklig tjeneste.  Men i første omgang er
 884 fokus på bokmålsoversettelsen, der vi selv har nok peiling til å ha
 885 fått oversatt 76%, men trenger hjelp for å komme helt i mål. :)</p>

 899       <div class="date">14th March 2014</div>
 900       <div class="body"><p>The <a href="https://wiki.debian.org/FreedomBox">Freedombox
 901 project</a> is working on providing the software and hardware for
 902 making it easy for non-technical people to host their data and
 903 communication at home, and being able to communicate with their
 904 friends and family encrypted and away from prying eyes.  It has been
 905 going on for a while, and is slowly progressing towards a new test
 906 release (0.2).</p>
 907
 908 <p>And what day could be better than the Pi day to announce that the
 909 new version will provide "hard drive" / SD card / USB stick images for
 910 Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization
 911 system), and can also be installed using a Debian installer preseed
 912 file.  The Debian based Freedombox is now based on Debian Jessie,
 913 where most of the needed packages used are already present.  Only one,
 914 the freedombox-setup package, is missing.  To try to build your own
 915 boot image to test the current status, fetch the freedom-maker scripts
 916 and build using
 917 <a href="http://packages.qa.debian.org/vmdebootstrap">vmdebootstrap</a>
 918 with a user with sudo access to become root:
 919
 920 <pre>
 921 git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
 922   freedom-maker
 923 sudo apt-get install git vmdebootstrap mercurial python-docutils \
 924   mktorrent extlinux virtualbox qemu-user-static binfmt-support \
 925   u-boot-tools
 926 make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
 927 </pre>
 928
 929 <p>Root access is needed to run debootstrap and mount loopback
 930 devices.  See the README for more details on the build. If you do not
 931 want all three images, trim the make line.  But note that thanks to <a
 932 href="https://bugs.debian.org/741407">a race condition in
 933 vmdebootstrap</a>, the build might fail without the patch to the
 934 kpartx call.</p>
 935
 936 <p>If you instead want to install using a Debian CD and the preseed
 937 method, boot a Debian Wheezy ISO and use this boot argument to load
 938 the preseed values:</p>
 939
 940 <pre>
 941 url=<a href="http://www.reinholdtsen.name/freedombox/preseed-jessie.dat">http://www.reinholdtsen.name/freedombox/preseed-jessie.dat</a>
 942 </pre>
 943
 944 <p>But note that due to <a href="https://bugs.debian.org/740673">a
 945 recently introduced bug in apt in Jessie</a>, the installer will
 946 currently hang while setting up APT sources.  Killing the
 947 '<tt>apt-cdrom ident</tt>' process when it hang a few times during the
 948 installation will get the installation going.  This affect all
 949 installations in Jessie, and I expect it will be fixed soon.</p>
 950
 951 <p>Give it a go and let us know how it goes on the mailing list, and help
 952 us get the new release published. :) Please join us on
 953 <a href="irc://irc.debian.org:6667/%23freedombox">IRC (#freedombox on
 954 irc.debian.org)</a> and
 955 <a href="http://lists.alioth.debian.org/mailman/listinfo/freedombox-discuss">the
 956 mailing list</a> if you want to help make this vision come true.</p>
