<a href=
"https://wiki.debian.org/FreedomBox">Freedombox
26 project
</a> is working on providing the software and hardware to make
27 it easy for non-technical people to host their data and communication
28 at home, and being able to communicate with their friends and family
29 encrypted and away from prying eyes. It is still going strong, and
30 today a major mile stone was reached.
</p>
32 <p>Today, the last of the packages currently used by the project to
33 created the system images were accepted into Debian Unstable. It was
34 the freedombox-setup package, which is used to configure the images
35 during build and on the first boot. Now all one need to get going is
36 the build code from the freedom-maker git repository and packages from
37 Debian. And once the freedombox-setup package enter testing, we can
38 build everything directly from Debian. :)
</p>
40 <p>Some key packages used by Freedombox are

49 documentation is maintained on the Debian wiki. Please
50 <a href=
"https://wiki.debian.org/FreedomBox/Manual/Jessie">check out
51 the manual
</a> and help us improve it.
</p>
53 <p>To test for yourself and create boot images with the FreedomBox
54 setup, run this on a Debian machine using a user with sudo rights to
58 sudo apt-get install git vmdebootstrap mercurial python-docutils \
59 mktorrent extlinux virtualbox qemu-user-static binfmt-support \
61 git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
63 make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
66 <p>Root access is needed to run debootstrap and mount loopback
67 devices. See the README in the freedom-maker git repo for more
68 details on the build. If you do not want all three images, trim the
69 make line. Note that the virtualbox-image target is not really
70 virtualbox specific. It create a x86 image usable in kvm, qemu,
71 vmware and any other x86 virtual machine environment. You might need
72 the version of vmdebootstrap in Jessie to get the build working, as it
73 include fixes for a race condition with kpartx.
</p>
75 <p>If you instead want to install using a Debian CD and the preseed
76 method, boot a Debian Wheezy ISO and use this boot argument to load
77 the preseed values:

</a>
83 <p>I have not tested it myself the last few weeks, so I do not know if
86 <p>If you wonder how to help, one task you could look at is using
87 systemd as the boot system. It will become the default for Linux in
88 Jessie, so we need to make sure it is usable on the Freedombox. I did
89 a simple test a few weeks ago, and noticed dnsmasq failed to start
90 during boot when using systemd. I suspect there are other problems
91 too. :) To detect problems, there is a test suite included, which can
92 be run from the plinth web interface.
</p>
94 <p>Give it a go and let us know how it goes on the mailing list, and help
95 us get the new release published. :) Please join us on

114 <div class=
"body"><p>For
12 år siden, skrev jeg et lite notat om
115 <a href=
"http://i18n.skolelinux.no/localekoder.txt">bruk av språkkoder
116 i Norge
</a>. Jeg ble nettopp minnet på dette da jeg fikk spørsmål om
117 notatet fortsatt var aktuelt, og tenkte det var greit å repetere hva
118 som fortsatt gjelder. Det jeg skrev da er fortsatt like aktuelt.
</p>
120 <p>Når en velger språk i programmer på unix, så velger en blant mange
121 språkkoder. For språk i Norge anbefales følgende språkkoder (anbefalt
122 locale i parantes):
</p>
125 <dt>nb (nb_NO)
</dt><dd>Bokmål i Norge
</dd>
126 <dt>nn (nn_NO)
</dt><dd>Nynorsk i Norge
</dd>
127 <dt>se (se_NO)
</dt><dd>Nordsamisk i Norge
</dd>
130 <p>Alle programmer som bruker andre koder bør endres.
</p>
132 <p>Språkkoden bør brukes når .po-filer navngis og installeres. Dette
133 er ikke det samme som locale-koden. For Norsk Bokmål, så bør filene
134 være navngitt nb.po, mens locale (LANG) bør være nb_NO.
</p>
136 <p>Hvis vi ikke får standardisert de kodene i alle programmene med
137 norske oversettelser, så er det umulig å gi LANG-variablen ett innhold
138 som fungerer for alle programmer.
</p>
140 <p>Språkkodene er de offisielle kodene fra ISO
639, og bruken av dem i
141 forbindelse med POSIX localer er standardisert i RFC
3066 og ISO
142 15897. Denne anbefalingen er i tråd med de angitte standardene.
</p>
144 <p>Følgende koder er eller har vært i bruk som locale-verdier for
145 "norske" språk. Disse bør unngås, og erstattes når de oppdages:
</p>
148 <tr><td>norwegian
</td><td>-
> nb_NO
</td></tr>
149 <tr><td>bokmål
</td><td>-
> nb_NO
</td></tr>
150 <tr><td>bokmal
</td><td>-
> nb_NO
</td></tr>
151 <tr><td>nynorsk
</td><td>-

154 <tr><td>no_NY
</td><td>-
> nn_NO
</td></tr>
155 <tr><td>sme_NO
</td><td>-
> se_NO
</td></tr>
158 <p>Merk at når det gjelder de samiske språkene, at se_NO i praksis
159 henviser til nordsamisk i Norge, mens f.eks. smj_NO henviser til
160 lulesamisk. Dette notatet er dog ikke ment å gi råd rundt samiske

</a></div>
202 <div class=

2014</div>
203 <div class=
"body"><p>For a while now, I have been looking for a sensible offsite backup
204 solution for use at home. My requirements are simple, it must be
205 cheap and locally encrypted (in other words, I keep the encryption
206 keys, the storage provider do not have access to my private files).
207 One idea me and my friends had many years ago, before the cloud
208 storage providers showed up, was to use Google mail as storage,
209 writing a Linux block device storing blocks as emails in the mail
210 service provided by Google, and thus get heaps of free space. On top
211 of this one can add encryption, RAID and volume management to have
212 lots of (fairly slow, I admit that) cheap and encrypted storage. But
213 I never found time to implement such system. But the last few weeks I
214 have looked at a system called
215 <a href=
"https://bitbucket.org/nikratio/s3ql/">S3QL
</a>, a locally
216 mounted network backed file system with the features I need.
</p>
218 <p>S3QL is a fuse file system with a local cache and cloud storage,
219 handling several different storage providers, any with Amazon S3,
220 Google Drive or OpenStack API. There are heaps of such storage
221 providers. S3QL can also use a local directory as storage, which
222 combined with sshfs allow for file storage on any ssh server. S3QL
223 include support for encryption, compression, de-duplication, snapshots
224 and immutable file systems, allowing me to mount the remote storage as
225 a local mount point, look at and use the files as if they were local,
226 while the content is stored in the cloud as well. This allow me to
227 have a backup that should survive fire. The file system can not be
228 shared between several machines at the same time, as only one can
229 mount it at the time, but any machine with the encryption key and
230 access to the storage service can mount it if it is unmounted.
</p>
232 <p>It is simple to use. I'm using it on Debian Wheezy, where the
233 package is included already. So to get started, run
<tt>apt-get
234 install s3ql
</tt>. Next, pick a storage provider. I ended up picking
235 Greenqloud, after reading their nice recipe on
236 <a href=
"https://greenqloud.zendesk.com/entries/44611757-How-To-Use-S3QL-to-mount-a-StorageQloud-bucket-on-Debian-Wheezy">how
237 to use S3QL with their Amazon S3 service
</a>, because I trust the laws
238 in Iceland more than those in USA when it come to keeping my personal
239 data safe and private, and thus would rather spend money on a company
240 in Iceland. Another nice recipe is available from the article
241 <a href=
"http://www.admin-magazine.com/HPC/Articles/HPC-Cloud-Storage">S3QL
242 Filesystem for HPC Storage
</a> by Jeff Layton in the HPC section of
243 Admin magazine. When the provider is picked, figure out how to get
244 the API key needed to connect to the storage API. With Greencloud,
245 the key did not show up until I had added payment details to my
248 <p>Armed with the API access details, it is time to create the file
249 system. First, create a new bucket in the cloud. This bucket is the
250 file system storage area. I picked a bucket name reflecting the
251 machine that was going to store data there, but any name will do.
252 I'll refer to it as
<tt>bucket-name
</tt> below. In addition, one need
253 the API login and password, and a locally created password. Store it
254 all in ~root/.s3ql/authinfo2 like this:
258 storage-url: s3c://s.greenqloud.com:
443/bucket-name
259 backend-login: API-login
260 backend-password: API-password
261 fs-passphrase: local-password
262 </pre></blockquote></p>
264 <p>I create my local passphrase using
<tt>pwget
50</tt> or similar,
265 but any sensible way to create a fairly random password should do it.
266 Armed with these details, it is now time to run mkfs, entering the API
267 details and password to create it:
</p>
270 # mkdir -m
700 /var/lib/s3ql-cache
271 # mkfs.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
272 --ssl s3c://s.greenqloud.com:
443/bucket-name
274 Enter backend password:
275 Before using S3QL, make sure to read the user's guide, especially
276 the 'Important Rules to Avoid Loosing Data' section.
277 Enter encryption password:

294 <p>The next step is mounting the file system to make the storage available.
297 # mount.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
298 --ssl --allow-root s3c://s.greenqloud.com:

317 <p>The file system is now ready for use. I use rsync to store my
318 backups in it, and as the metadata used by rsync is downloaded at
319 mount time, no network traffic (and storage cost) is triggered by
320 running rsync. To unmount, one should not use the normal umount
321 command, as this will not flush the cache to the cloud storage, but
322 instead running the umount.s3ql command like this:
327 </pre></blockquote></p>
329 <p>There is a fsck command available to check the file system and
330 correct any problems detected. This can be used if the local server
331 crashes while the file system is mounted, to reset the "already
332 mounted" flag. This is what it look like when processing a working

381 <p>Thanks to the cache, working on files that fit in the cache is very
382 quick, about the same speed as local file access. Uploading large
383 amount of data is to me limited by the bandwidth out of and into my
384 house. Uploading
685 MiB with a
100 MiB cache gave me
305 kiB/s,
385 which is very close to my upload speed, and downloading the same
386 Debian installation ISO gave me
610 kiB/s, close to my download speed.
387 Both were measured using
<tt>dd
</tt>. So for me, the bottleneck is my
388 network, not the file system code. I do not know what a good cache
389 size would be, but suspect that the cache should e larger than your
392 <p>I mentioned that only one machine can mount the file system at the
393 time. If another machine try, it is told that the file system is
397 # mount.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
398 --ssl --allow-root s3c://s.greenqloud.com:

8 upload threads.
400 Backend reports that fs is still mounted elsewhere, aborting.

404 <p>The file content is uploaded when the cache is full, while the
405 metadata is uploaded once every
24 hour by default. To ensure the
406 file system content is flushed to the cloud, one can either umount the
407 file system, or ask S3QL to flush the cache and metadata using
411 # s3qlctrl upload-meta /s3ql
412 # s3qlctrl flushcache /s3ql
414 </pre></blockquote></p>
416 <p>If you are curious about how much space your data uses in the
417 cloud, and how much compression and deduplication cut down on the
418 storage usage, you can use s3qlstat on the mounted file system to get
423 Directory entries:

22049.38 MB

99.22% of total,
99.64% of de-duplicated)

434 <p>I mentioned earlier that there are several possible suppliers of
435 storage. I did not try to locate them all, but am aware of at least

446 <p>While researching this blog post, I had a look at research papers
447 and posters discussing the S3QL file system. There are several, which
448 told me that the file system is getting a critical check by the
449 science community and increased my confidence in using it. One nice

455 and Pamela Smith. Please have a look.</p>
457 <p>Given my problems with different file systems earlier, I decided to
458 check out the mounted S3QL file system to see if it would be usable as
459 a home directory (in other word, that it provided POSIX semantics when
460 it come to locking and umask handling etc). Running

464 directories, if one chooses to do so.</p>

"><p>Microsoft have announced that Windows XP reaches its end of life
579 2014-04-08, in 7 days. But there are heaps of machines still running
580 Windows XP, and depending on Windows XP to run their applications, and
581 upgrading will be expensive, both when it comes to money and when it
582 comes to the amount of effort needed to migrate from Windows XP to a
583 new operating system. Some obvious options (buy new a Windows
584 machine, buy a MacOSX machine, install Linux on the existing machine)
585 are already well known and covered elsewhere. Most of them involve
586 leaving the user applications installed on Windows XP behind and
587 trying out replacements or updated versions. In this blog post I want
588 to mention one strange bird that allow people to keep the hardware and
589 the existing Windows XP applications and run them on a free software
590 operating system that is Windows XP compatible.</p>
592 <p><a href="http://www.reactos.org/
">ReactOS</a> is a free software
593 operating system (GNU GPL licensed) working on providing a operating
594 system that is binary compatible with Windows, able to run windows
595 programs directly and to use Windows drivers for hardware directly.
596 The project goal is for Windows user to keep their existing machines,
597 drivers and software, and gain the advantages from user a operating
598 system without usage limitations caused by non-free licensing. It is
599 a Windows clone running directly on the hardware, so quite different
600 from the approach taken by <a href="http://www.winehq.org/
">the Wine
601 project</a>, which make it possible to run Windows binaries on
604 <p>The ReactOS project share code with the Wine project, so most
605 shared libraries available on Windows are already implemented already.
606 There is also a software manager like the one we are used to on Linux,
607 allowing the user to install free software applications with a simple
608 click directly from the Internet. Check out the
609 <a href="http://www.reactos.org/screenshots
">screen shots on the
610 project web site</a> for an idea what it look like (it looks just like
611 Windows before metro).</p>
613 <p>I do not use ReactOS myself, preferring Linux and Unix like
614 operating systems. I've tested it, and it work fine in a virt-manager
615 virtual machine. The browser, minesweeper, notepad etc is working
616 fine as far as I can tell. Unfortunately, my main test application
617 is the software included on a CD with the Lego Mindstorms NXT, which
618 seem to install just fine from CD but fail to leave any binaries on
619 the disk after the installation. So no luck with that test software.
620 No idea why, but hope someone else figure out and fix the problem.
621 I've tried the ReactOS Live ISO on a physical machine, and it seemed
622 to work just fine. If you like Windows and want to keep running your
623 old Windows binaries, check it out by

641 <div class="body
"><p><a href="http://www.skolelinux.org/
">Debian Edu / Skolelinux</a>
642 keep gaining new users. Some weeks ago, a person showed up on IRC,
643 <a href="irc://irc.debian.org/#debian-edu
">#debian-edu</a>, with a
644 wish to contribute, and I managed to get a interview with this great
645 contributor Roger Marsal to learn more about his background.</p>
647 <p><strong>Who are you, and how do you spend your days?</strong></p>
649 <p>My name is Roger Marsal, I'm 27 years old (1986 generation) and I
650 live in Barcelona, Spain. I've got a strong business background and I
651 work as a patrimony manager and as a real estate agent. Additionally,
652 I've co-founded a British based tech company that is nowadays on the
653 last development phase of a new social networking concept.</p>
655 <p>I'm a Linux enthusiast that started its journey with Ubuntu four years
656 ago and have recently switched to Debian seeking rock solid stability
657 and as a necessary step to gain expertise.</p>
659 <p>In a nutshell, I spend my days working and learning as much as I
660 can to face both my job, entrepreneur project and feed my Linux
663 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
664 project?</strong></p>
666 <p>I discovered the <a href="http://www.ltsp.org/
">LTSP</a> advantages
667 with "Ubuntu
12.04 alternate install" and after a year of use I
668 started looking for an alternative. Even though I highly value and
669 respect the Ubuntu project, I thought it was necessary for me to
670 change to a more robust and stable alternative. As far as I was using
671 Debian on my personal laptop I thought it would be fine to install
672 Debian and configure an LTSP server myself. Surprised, I discovered
673 that the Debian project also supported a kind of Edubuntu equivalent,
674 and after having some pain I obtained a Debian Edu network up and
675 running. I just loved it.
</p>
677 <p><strong>What do you see as the advantages of Skolelinux / Debian
680 <p>I found a main advantage in that, once you know "the tips and
681 tricks", a new installation just works out of the box. It's the most
682 complete alternative I've found to create an LTSP network. All the
683 other distributions seems to be made of plastic, Debian Edu seems to
684 be made of steel.
</p>
686 <p><strong>What do you see as the disadvantages of Skolelinux / Debian
689 <p>I found two main disadvantages.
</p>
691 <p>I'm not an expert but I've got notions and I had to spent a considerable
692 amount of time trying to bring up a standard network topology. I'm quite
693 stubborn and I just worked until I did but I'm sure many people with few
694 resources (not big schools, but academies for example) would have switched
697 <p>It's amazing how such a complex system like Debian Edu has achieved
698 this out-of-the-box state. Even though tweaking without breaking gets
699 more difficult, as more factors have to be considered. This can
700 discourage many people too.
</p>
702 <p><strong>Which free software do you use daily?
</strong></p>
704 <p>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
708 <p><strong>Which strategy do you believe is the right one to use to
709 get schools to use free software?
</strong></p>
711 <p>I don't think there is a need for a particular strategy. The free
712 attribute in both "freedom" and "no price" meanings is what will
713 really bring free software to schools. In my experience I can think of
714 the
<a href=
"http://www.r-project.org/">"R" statistical language
</a>; a
715 few years a ago was an extremely nerd tool for university people.
716 Today it's being increasingly used to teach statistics at many
717 different level of studies. I believe free and open software will
718 increasingly gain popularity, but I'm sure schools will be one of the
719 first scenarios where this will happen.

742 Jeg har sett dokumentaren, og jeg anbefaler enhver å se den selv. Som

747 retten til privatliv og beskyttelsen av demokrati i Norge og resten
748 verden, og helt riktig slår fast at det er vi i databransjen som
749 sitter med nøkkelen til å gjøre noe med dette. Jeg har involvert meg
750 i prosjektene

774 <div class=
"body"><p>Did you ever need to store logs or other files in a way that would
775 allow it to be used as evidence in court, and needed a way to
776 demonstrate without reasonable doubt that the file had not been
777 changed since it was created? Or, did you ever need to document that
778 a given document was received at some point in time, like some
779 archived document or the answer to an exam, and not changed after it
780 was received? The problem in these settings is to remove the need to
781 trust yourself and your computers, while still being able to prove
782 that a file is the same as it was at some given time in the past.
</p>
784 <p>A solution to these problems is to have a trusted third party
785 "stamp" the document and verify that at some given time the document
786 looked a given way. Such
787 <a href=
"https://en.wikipedia.org/wiki/Notarius">notarius
</a> service
788 have been around for thousands of years, and its digital equivalent is
790 <a href=
"http://en.wikipedia.org/wiki/Trusted_timestamping">trusted
791 timestamping service
</a>.
<a href=
"http://www.ietf.org/">The Internet
792 Engineering Task Force
</a> standardised how such service could work a
793 few years ago as
<a href=
"http://tools.ietf.org/html/rfc3161">RFC
794 3161</a>. The mechanism is simple. Create a hash of the file in
795 question, send it to a trusted third party which add a time stamp to
796 the hash and sign the result with its private key, and send back the
797 signed hash + timestamp. Both email, FTP and HTTP can be used to
798 request such signature, depending on what is provided by the service
799 used. Anyone with the document and the signature can then verify that
800 the document matches the signature by creating their own hash and
801 checking the signature using the trusted third party public key.
802 There are several commercial services around providing such
803 timestamping. A quick search for
804 "
<a href=
"https://duckduckgo.com/?q=rfc+3161+service">rfc
3161
805 service
</a>" pointed me to at least
806 <a href="https://www.digistamp.com/technical/how-a-digital-time-stamp-works/

">Global
811 Trust Finder</a>. The system work as long as the private key of the
812 trusted third party is not compromised.</p>
814 <p>But as far as I can tell, there are very few public trusted
815 timestamp services available for everyone. I've been looking for one
816 for a while now. But yesterday I found one over at
817 <a href="https://www.pki.dfn.de/zeitstempeldienst/

819 <a href="http://www.d-mueller.de/blog/dealing-with-trusted-timestamps-in-php-rfc-

820 blog by David Müller</a>. I then found
821 <a href="http://www.rz.uni-greifswald.de/support/dfn-pki-zertifikate/zeitstempeldienst.html
">a
822 good recipe on how to use the service</a> over at the University of
825 <p><a href="http://www.openssl.org/
">The OpenSSL library</a> contain
826 both server and tools to use and set up your own signing service. See
827 the ts(1SSL), tsget(1SSL) manual pages for more details. The
828 following shell script demonstrate how to extract a signed timestamp
829 for any file on the disk in a Debian environment:</p>
834 url="http://zeitstempel.dfn.de"
835 caurl="https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt"
836 reqfile=$(mktemp -t tmp.XXXXXXXXXX.tsq)
837 resfile=$(mktemp -t tmp.XXXXXXXXXX.tsr)
839 if [ ! -f $cafile ] ; then
840 wget -O $cafile "$caurl"
842 openssl ts -query -data "$
1" -cert | tee "$reqfile" \
843 | /usr/lib/ssl/misc/tsget -h "$url" -o "$resfile"
844 openssl ts -reply -in "$resfile" -text
1>&
2
845 openssl ts -verify -data "$
1" -in "$resfile" -CAfile "$cafile"
1>&
2
847 rm "$reqfile" "$resfile"
848 </pre></blockquote></p>
850 <p>The argument to the script is the file to timestamp, and the output
851 is a base64 encoded version of the signature to STDOUT and details
852 about the signature to STDERR. Note that due to
853 <a href=
"http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=742553">a bug
854 in the tsget script
</a>, you might need to modify the included script
855 and remove the last line. Or just write your own HTTP uploader using
856 curl. :) Now you too can prove and verify that files have not been

8 characters
</a>, which according to
906 Bastian is against the DVD specification (and seem to cause some
907 players to fail too). A rarer problem is what seem to be inconsistent
908 DVD structures, as the python library
909 <a href=
"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079">claim
910 there is a overlap between objects
</a>. An equally rare problem claim
911 <a href=
"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741878">some
912 value is out of range
</a>. No idea what is going on there. I wish I
913 knew enough about the DVD format to fix these, to ensure my movie
914 collection will stay with me in the future.
</p>
916 <p>So, if you need to keep your DVDs safe, back them up using
917 python-dvdvideo. :)

932 <div class=
"body"><p>Det offentlige Norge har mye kunnskap og informasjon. Men hvordan
933 kan en få tilgang til den på en enkel måte? Takket være et lite
934 knippe lover og tilhørende forskrifter, blant annet
935 <a href=
"http://lovdata.no/dokument/NL/lov/2006-05-19-16">offentlighetsloven
</a>,
936 <a href=
"http://lovdata.no/dokument/NL/lov/2003-05-09-31">miljøinformasjonsloven
</a>
938 <a href=
"http://lovdata.no/dokument/NL/lov/1967-02-10/">forvaltningsloven
</a>
939 har en rett til å spørre det offentlige og få svar. Men det finnes
940 intet offentlig arkiv over hva andre har spurt om, og dermed risikerer en
941 å måtte forstyrre myndighetene gang på gang for å få tak i samme
942 informasjonen på nytt.
<a href=
"http://www.mysociety.org/">Britiske
943 mySociety
</a> har laget tjenesten
944 <a href=
"http://www.whatdotheyknow.com/">WhatDoTheyKnow
</a> som gjør
945 noe med dette. I Storbritannia blir WhatdoTheyKnow brukt i
946 <a href=
"http://www.mysociety.org/2011/07/01/whatdotheyknows-share-of-central-government-foi-requests-q2-2011/">ca
947 15% av alle innsynsforespørsler mot sentraladministrasjonen
</a>.
948 Prosjektet heter
<a href=
"http://www.alaveteli.org/">Alaveteli
</A>, og
949 er takk i bruk en rekke steder etter at løsningen ble generalisert og
950 gjort mulig å oversette. Den hjelper borgerne med å be om innsyn,
951 rådgir ved purringer og klager og lar alle se hvilke henvendelser som
952 er sendt til det offentlige og hvilke svar som er kommet inn, i et
953 søkpart arkiv. Her i Norge holder vi i foreningen NUUG på å få opp en
954 norsk utgave av Alaveteli, og her trenger vi din hjelp med
957 <p>Så langt er
76 % av Alaveteli oversatt til norsk bokmål, men vi
958 skulle gjerne vært oppe i
100 % før lansering. Oversettelsen gjøres
959 på
<a href=
"https://www.transifex.com/projects/p/alaveteli/">Transifex,
960 der enhver som registrerer seg
</a> og ber om tilgang til
961 bokmålsoversettelsen får bidra. Vi har satt opp en test av tjenesten
962 (som ikke sender epost til det offentlige, kun til oss som holder på å
963 sette opp tjenesten) på maskinen
964 <a href=
"http://alaveteli-dev.nuug.no/">alaveteli-dev.nuug.no
</a>, der
965 en kan se hvordan de oversatte meldingen blir seende ut på nettsiden.
966 Når tjenesten lanseres vil den hete
967 <a href=
"https://www.mimesbrønn.no/">Mimes brønn
</a>, etter
968 visdomskilden som Odin måtte gi øyet sitt for å få drikke i. Den
969 nettsiden er er ennå ikke klar til bruk.
</p>
971 <p>Hvis noen vil oversette til nynorsk også, så skal vi finne ut
972 hvordan vi lager en flerspråklig tjeneste. Men i første omgang er
973 fokus på bokmålsoversettelsen, der vi selv har nok peiling til å ha
974 fått oversatt
76%, men trenger hjelp for å komme helt i mål. :)
