The last few days I came across a few good causes that should get -wider attention. I recommend signing and donating to each one of -these. :)
- -Via Debian -Project News for 2013-10-14 I came across the Outreach Program for -Women program which is a Google Summer of Code like initiative to get -more women involved in free software. One debian sponsor has offered -to match any donation done to Debian -earmarked for this initiative. I donated a few minutes ago, and -hope you will to. :)
- -And the Electronic Frontier Foundation just announced plans to -create video -documentaries about the excessive spying on every Internet user that -take place these days, and their need to fund the work. I've already -donated. Are you next?
- -For my Norwegian audience, the organisation Studentenes og -Akademikernes Internasjonale Hjelpefond is collecting signatures for a -statement under the heading -Bloggers United for Open -Access for those of us asking for more focus on open access in the -Norwegian government. So far 499 signatures. I hope you will sign it -too.
+ +Yesterday, I had the pleasure of attending a talk with the +Norwegian Unix User Group about +the +OpenPGP keyserver pool sks-keyservers.net, and was very happy to +learn that there is a large set of publicly available key servers to +use when looking for peoples public key. So far I have used +subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former +were misbehaving, but those days are ended. The servers I have used +up until yesterday have been slow and some times unavailable. I hope +those problems are gone now.
+ +Behind the round robin DNS entry of the +sks-keyservers.net service +there is a pool of more than 100 keyservers which are checked every +day to ensure they are well connected and up to date. It must be +better than what I have used so far. :)
+ +Yesterdays speaker told me that the service is the default +keyserver provided by the default configuration in GnuPG, but this do +not seem to be used in Debian. Perhaps it should?
+ +Anyway, I've updated my ~/.gnupg/options file to now include this +line:
+ ++ ++keyserver pool.sks-keyservers.net +
With GnuPG version 2 one can also locate the keyserver using SRV +entries in DNS. Just for fun, I did just that at work, so now every +user of GnuPG at the University of Oslo should find a OpenGPG +keyserver automatically should their need it:
+ ++ ++% host -t srv _pgpkey-http._tcp.uio.no +_pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net. +% +
Now if only +the +HKP lookup protocol supported finding signature paths, I would be +very happy. It can look up a given key or search for a user ID, but I +normally do not want that, but to find a trust path from my key to +another key. Given a user ID or key ID, I would like to find (and +download) the keys representing a signature path from my key to the +key in question, to be able to get a trust path between the two keys. +This is as far as I can tell not possible today. Perhaps something +for a future version of the protocol?
Wireless mesh networks are self organising and self healing -networks that can be used to connect computers across small and large -areas, depending on the radio technology used. Normal wifi equipment -can be used to create home made radio networks, and there are several -successful examples like -Freifunk and -Athens Wireless Metropolitan Network -(see -wikipedia -for a large list) around the globe. To give you an idea how it -work, check out the nice overview of the Kiel Freifunk community which -can be seen from their -dynamically -updated node graph and map, where one can see how the mesh nodes -automatically handle routing and recover from nodes disappearing. -There is also a small community mesh network group in Oslo, Norway, -and that is the main topic of this blog post.
- -I've wanted to check out mesh networks for a while now, and hoped -to do it as part of my involvement with the NUUG member organisation community, and -my recent involvement in -the Freedombox project -finally lead me to give mesh networks some priority, as I suspect a -Freedombox should use mesh networks to connect neighbours and family -when possible, given that most communication between people are -between those nearby (as shown for example by research on Facebook -communication patterns). It also allow people to communicate without -any central hub to tap into for those that want to listen in on the -private communication of citizens, which have become more and more -important over the years.
- -So far I have only been able to find one group of people in Oslo -working on community mesh networks, over at the hack space -Hackeriet at Husmania. They seem to -have started with some Freifunk based effort using OLSR, called -the Oslo -Freifunk project, but that effort is now dead and the people -behind it have moved on to a batman-adv based system called -meshfx. Unfortunately the wiki -site for the Oslo Freifunk project is no longer possible to update to -reflect this fact, so the old project page can't be updated to point to -the new project. A while back, the people at Hackeriet invited people -from the Freifunk community to Oslo to talk about mesh networks. I -came across this video where Hans Jørgen Lysglimt interview the -speakers about this talk (from -youtube):
- - - -I mentioned OLSR and batman-adv, which are mesh routing protocols. -There are heaps of different protocols, and I am still struggling to -figure out which one would be "best" for some definitions of best, but -given that the community mesh group in Oslo is so small, I believe it -is best to hook up with the existing one instead of trying to create a -completely different setup, and thus I have decided to focus on -batman-adv for now. It sure help me to know that the very cool -Serval project in Australia -is using batman-adv as their meshing technology when it create a self -organizing and self healing telephony system for disaster areas and -less industrialized communities. Check out this cool video presenting -that project (from -youtube):
- - - -According to the wikipedia page on -Wireless -mesh network there are around 70 competing schemes for routing -packets across mesh networks, and OLSR, B.A.T.M.A.N. and -B.A.T.M.A.N. advanced are protocols used by several free software -based community mesh networks.
- -The batman-adv protocol is a bit special, as it provide layer 2 -(as in ethernet ) routing, allowing ipv4 and ipv6 to work on the same -network. One way to think about it is that it provide a mesh based -vlan you can bridge to or handle like any other vlan connected to your -computer. The required drivers are already in the Linux kernel at -least since Debian Wheezy, and it is fairly easy to set up. A -good -introduction is available from the Open Mesh project. These are -the key settings needed to join the Oslo meshfx network:
- -Setting | Value |
---|---|
Protocol / kernel module | batman-adv |
ESSID | meshfx@hackeriet | Channel / Frequency | 11 / 2462 | -Cell ID | 02:BA:00:00:00:01 | -
The reason for setting ad-hoc wifi Cell ID is to work around bugs -in firmware used in wifi card and wifi drivers. (See a nice post from -VillageTelco about -"Information -about cell-id splitting, stuck beacons, and failed IBSS merges! -for details.) When these settings are activated and you have some -other mesh node nearby, your computer will be connected to the mesh -network and can communicate with any mesh node that is connected to -any of the nodes in your network of nodes. :)
- -My initial plan was to reuse my old Linksys WRT54GL as a mesh node, -but that seem to be very hard, as I have not been able to locate a -firmware supporting batman-adv. If anyone know how to use that old -wifi access point with batman-adv these days, please let me know.
- -If you find this project interesting and want to join, please join -us on IRC, either channel -#oslohackerspace -or #nuug on -irc.freenode.net.
- -While investigating mesh networks in Oslo, I came across an old -research paper from the university of Stavanger and Telenor Research -and Innovation called -The -reliability of wireless backhaul mesh networks and elsewhere -learned that Telenor have been experimenting with mesh networks at -Grünerløkka in Oslo. So mesh networks are also interesting for -commercial companies, even though Telenor discovered that it was hard -to figure out a good business plan for mesh networking and as far as I -know have closed down the experiment. Perhaps Telenor or others would -be interested in a cooperation?
- -Update 2013-10-12: I was just -told -by the Serval project developers that they no longer use -batman-adv (but are compatible with it), but their own crypto based -mesh system.
+ +Two years later, I am still not sure if it is legal here in Norway +to use or publish a video in H.264 or MPEG4 format edited by the +commercially licensed video editors, without limiting the use to +create "personal" or "non-commercial" videos or get a license +agreement with MPEG LA. If one +want to publish and broadcast video in a non-personal or commercial +setting, it might be that those tools can not be used, or that video +format can not be used, without breaking their copyright license. I +am not sure. +Back +then, I found that the copyright license terms for Adobe Premiere +and Apple Final Cut Pro both specified that one could not use the +program to produce anything else without a patent license from MPEG +LA. The issue is not limited to those two products, though. Other +much used products like those from Avid and Sorenson Media have terms +of use are similar to those from Adobe and Apple. The complicating +factor making me unsure if those terms have effect in Norway or not is +that the patents in question are not valid in Norway, but copyright +licenses are.
+ +These are the terms for Avid Artist Suite, according to their +published +end user +license +text (converted to lower case text for easier reading):

The other day I was pleased and surprised to discover that Marcelo -Salvador had published a -video on -Youtube showing how to install the standalone Debian Edu / -Skolelinux profile. This is the profile intended for use at home or -on laptops that should not be integrated into the provided network -services (no central home directory, no Kerberos / LDAP directory etc, -in other word a single user machine). The result is 11 minutes long, -and show some user applications (seem to be rather randomly picked). -Missed a few of my favorites like celestia, planets and chromium -showing the Zygote Body 3D model -of the human body, but I guess he did not know about those or find -other programs more interesting. :) And the video do not show the -advantages I believe is one of the most valuable featuers in Debian -Edu, its central school server making it possible to run hundreds of -computers without hard drives by installing one central -LTSP server.
- -Anyway, check out the video, embedded below and linked to above:
- - - -Are there other nice videos demonstrating Skolelinux? Please let -me know. :)

A few hours ago, the announcement for the first stable release of -Debian Edu Wheezy went out from the Debian publicity team. The -complete announcement text can be found at -the Debian News -section, translated to several languages. Please check it out.
- -There is one minor known problem that we will fix very soon. One -can not install a amd64 Thin Client Server using PXE, as the /var/ -partition is too small. A workaround is to extend the partition (use -lvresize + resize2fs in tty 2 while installing).
+ +The complete and free âout of the boxâ software solution for +schools, Debian Edu / +Skolelinux, is used quite a lot in Germany, and one of the people +involved is Bernd Zeitzen, who show up on the project mailing lists +from time to time with interesting questions and tips on how to adjust +the setup. I managed to interview him this summer.
+ +Who are you, and how do you spend your days?
+ +My name is Bernd Zeitzen and I'm married with Hedda, a self +employed physiotherapist. My former profession is tool maker, but I +haven't worked for 30 years in this job. 30 years ago I started to +support my wife and become her officeworker and a few years later the +administrator for a small computer network, today based on Ubuntu +Server (Samba, OpenVPN). For her daily work she has to use Windows +Desktops because the software she needs to organize her business only +works with Windows . :-(
+ +In 1988 we started with one PC and DOS, then I learned to use +Windows 98, 2000, XP, â¦, 8, Ubuntu, MacOSX. Today we are running a +Linux server with 6 Windows clients and 10 persons (teacher of +children with special needs, speech therapist, occupational therapist, +psychologist and officeworkers) using our Samba shares via OpenVPN to +work with the documentations of our patients.
+ +How did you get in contact with the Skolelinux / Debian Edu +project?
+ +Two years ago a friend of mine asked me, if I want to get a job in +his school (Gymnasium +Harsewinkel). They started with Skolelinux / Debian Edu and they +were looking for people to give support to the teachers using the +software and the network and teaching the pupils increasing their +computer skills in optional lessons. I'm spending 4-6 hours a week +with this job.
+ +What do you see as the advantages of Skolelinux / Debian +Edu?
+ +The independence.
+ +First: Every person is allowed to use, share and develop the +software. Even if you are poor, you are allowed to use the software +included in Skolelinux/Debian Edu and all the other Free Software.
+ +Second: The software runs on old machines and this gives us the +possibility to recycle computers, weeded out from offices. The +servers and desktops are running for more than two years and they are +working reliable.
+ +We have two servers (one tjener and one terminal server), 45 +workstations in three classrooms and seven laptops as a mobile +solution for all classrooms. These machines are all booting from the +terminal server. In the moment we are installing 30 laptops as mobile +workstations. Then the pupils have the possibility to work with these +machines in their classrooms. Internet access is realized by a WLAN +router, connected to the schools network. This is all done without a +dedicated system administrator or a computer science teacher.
+ +What do you see as the disadvantages of Skolelinux / Debian +Edu?
+ +Teachers and pupils are Windows users. <Irony on> And Linux +isn't cool. It's software for freaks using the command line. <Irony +off> They don't realize the stability of the system.
+ +Which free software do you use daily?
+ +Firefox, Thunderbird, LibreOffice, Ubuntu Server 12.04 (Samba, +Apache, MySQL, Joomla!, ⦠and Skolelinux / Debian Edu)
+ +Which strategy do you believe is the right one to use to +get schools to use free software?
+ +In Germany we have the situation: every school is free to decide +which software they want to use. This decision is influenced by +teachers who learned to use Windows and MS Office. They buy a PC with +Windows preinstalled and an additional testing version of MS +Office. They don't know about the possibility to use Free Software +instead. Another problem are the publisher of school books. They +develop their software, added to the school books, for Windows.

+ +This summer I finally had time to continue working on the Norwegian +docbook version of the 2004 book +Free Culture by Lawrence Lessig, +to get a Norwegian text explaining the problems with todays copyright +law. Yesterday, I finally completed translated the book text. There +are still some foot/end notes left to translate, the colophon page +need to be rewritten, and a few words and phrases still need to be +translated, but the Norwegian text is ready for the first proof +reading. :) More spell checking is needed, and several illustrations +need to be cleaned up. The work stopped up because I had to give +priority to other projects the last year, and the progress graph of +the translation show this very well:
+ +If you want to read the result, check out the +github +project pages and the +PDF, +EPUB +and HTML version available in the +archive +directory.

- -Debian Edu, also known as Skolelinux, is a Linux distribution based -on Debian providing an out-of-the box environment of a completely -configured school network. Immediately after installation a school -server running all services needed for a school network is set up just -waiting for users and machines being added via GOsa², a comfortable -Web-UI. A netbooting environment is prepared using PXE, so after -initial installation of the main server from CD or USB stick all other -machines can be installed via the network. The provided school server -provides LDAP database and Kerberos authentication service, -centralized home directories, DHCP server, web proxy and many other -services. The desktop contains more than 60 educational software -packages and more are available from the Debian archive, and schools -can choose between KDE, Gnome, LXDE and Xfce desktop environment.
- -This is the seventh test release based on Debian Wheezy. Basically -this is an updated and slightly improved version compared to the -Squeeze release.
- -Notes for upgrades from Alpha Prereleases
- -Alpha based installations should reinstall or downgrade the -versions of gosa and libpam-mklocaluser to the ones used in this beta -release. Both alpha and beta0 based installations should reinstall or -deal with gosa.conf manually; there are two options: (1) Keep -gosa.conf and edit this file as outlined on the mailing list. (2) -Accept the new version of gosa.conf and replace both contained admin -password placeholders with the password hashes found in the old one -(backup copy!). In both cases all users need to change their password -to make sure a password is set for CIFS access to their home -directory.

The Debian Edu / Skolelinux +project provide an instruction manual for teachers, system +administrators and other users that contain useful tips for setting up +and maintaining a Debian Edu installation. This text is about how the +text processing of this manual is handled in the project.
+ +One goal of the project is to provide information in the native +language of its users, and for this we need to handle translations. +But we also want to make sure each language contain the same +information, so for this we need a good way to keep the translations +in sync. And we want it to be easy for our users to improve the +documentation, avoiding the need to learn special formats or tools to +contribute, and the obvious way to do this is to make it possible to +edit the documentation using a web browser. We also want it to be +easy for translators to keep the translation up to date, and give them +help in figuring out what need to be translated. Here is the list of +tools and the process we have found trying to reach all these +goals.
+ +We maintain the authoritative source of our manual in the +Debian +wiki, as several wiki pages written in English. It consist of one +front page with references to the different chapters, several pages +for each chapter, and finally one "collection page" gluing all the +chapters together into one large web page (aka +the +AllInOne page). The AllInOne page is the one used for further +processing and translations. Thanks to the fact that the +MoinMoin installation on +wiki.debian.org support exporting pages in +the Docbook format, we can fetch +the list of pages to export using the raw version of the AllInOne +page, loop over each of them to generate a Docbook XML version of the +manual. This process also download images and transform image +references to use the locally downloaded images. The generated +Docbook XML files are slightly broken, so some post-processing is done +using the documentation/scripts/get_manual program, and the +result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and +a handfull of images. The XML file can now be used to generate PDF, HTML +and epub versions of the English manual. This is the basic step of +our process, making PDF (using dblatex), HTML (using xsltproc) and +epub (using dbtoepub) version from Docbook XML, and the resulting files +are placed in the debian-edu-doc-en binary package.
+ +But English documentation is not enough for us. We want translated +documentation too, and we want to make it easy for translators to +track the English original. For this we use the +poxml package, +which allow us to transform the English Docbook XML file into a +translation file (a .pot file), usable with the normal gettext based +translation tools used by those translating free software. The pot +file is used to create and maintain translation files (several .po +files), which the translations update with the native language +translations of all titles, paragraphs and blocks of text in the +original. The next step is combining the original English Docbook XML +and the translation file (say debian-edu-wheezy-manual.nb.po), to +create a translated Docbook XML file (in this case +debian-edu-wheezy-manual.nb.xml). This translated (or partly +translated, if the translation is not complete) Docbook XML file can +then be used like the original to create a PDF, HTML and epub version +of the documentation.
+ +The translators use different tools to edit the .po files. We +recommend using +lokalize, +while some use emacs and vi, others can use web based editors like +Poodle or +Transifex. All we care about +is where the .po file end up, in our git repository. Updated +translations can either be committed directly to git, or submitted as +bug reports +against the debian-edu-doc package.
+ +One challenge is images, which both might need to be translated (if +they show translated user applications), and are needed in different +formats when creating PDF and HTML versions (epub is a HTML version in +this regard). For this we transform the original PNG images to the +needed density and format during build, and have a way to provide +translated images by storing translated versions in +images/$LANGUAGECODE/. I am a bit unsure about the details here. The +package maintainers know more.
+ +If you wonder what the result look like, we provide +the content +of the documentation packages on the web. See for example the +Italian +PDF version or the +German +HTML version. We do not yet build the epub version by default, +but perhaps it will be done in the future.
+ +To learn more, check out +the +debian-edu-doc package, +the +manual on the wiki and +the +translation instructions in the manual.
I was introduced to the -Freedombox project -in 2010, when Eben Moglen presented his vision about serving the need -of non-technical people to keep their personal information private and -within the legal protection of their own homes. The idea is to give -people back the power over their network and machines, and return -Internet back to its intended peer-to-peer architecture. Instead of -depending on a central service, the Freedombox will give everyone -control over their own basic infrastructure.
- -I've intended to join the effort since then, but other tasks have -taken priority. But this summers nasty news about the misuse of trust -and privilege exercised by the "western" intelligence gathering -communities increased my eagerness to contribute to a point where I -actually started working on the project a while back.
- -The initial -Debian initiative based on the vision from Eben Moglen, is to -create a simple and cheap Debian based appliance that anyone can hook -up in their home and get access to secure and private services and -communication. The initial deployment platform have been the -Dreamplug, -which is a piece of hardware I do not own. So to be able to test what -the current Freedombox setup look like, I had to come up with a way to install -it on some hardware I do have access to. I have rewritten the -freedom-maker -image build framework to use .deb packages instead of only copying -setup into the boot images, and thanks to this rewrite I am able to -set up any machine supported by Debian Wheezy as a Freedombox, using -the previously mentioned deb (and a few support debs for packages -missing in Debian).
- -The current Freedombox setup consist of a set of bootstrapping -scripts -(freedombox-setup), -and a administrative web interface -(plinth + exmachina + -withsqlite), as well as a privacy enhancing proxy based on -privoxy -(freedombox-privoxy). There is also a web/javascript based XMPP -client (jwchat) -trying (unsuccessfully so far) to talk to the XMPP server -(ejabberd). The -web interface is pluggable, and the goal is to use it to enable OpenID -services, mesh network connectivity, use of TOR, etc, etc. Not much of -this is really working yet, see -the -project TODO for links to GIT repositories. Most of the code is -on github at the moment. The HTTP proxy is operational out of the -box, and the admin web interface can be used to add/remove plinth -users. I've not been able to do anything else with it so far, but -know there are several branches spread around github and other places -with lots of half baked features.
- -Anyway, if you want to have a look at the current state, the -following recipes should work to give you a test machine to poke -at.
- -Debian Wheezy amd64
- --
-
-
- Fetch normal Debian Wheezy installation ISO. -
- Boot from it, either as CD or USB stick. -
Press [tab] on the boot prompt and add this as a boot argument -to the Debian installer:
-
url=http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat
-
-- Answer the few language/region/password questions and pick disk to -install on. - -
- When the installation is finished and the machine have rebooted a -few times, your Freedombox is ready for testing. - -
Raspberry Pi Raspbian
- --
-
-
- Fetch a Raspbian SD card image, create SD card. -
- Boot from SD card, extend file system to fill the card completely. -
Log in and add this to /etc/sources.list:
--deb http://www.reinholdtsen.name/freedombox wheezy main -
-Run this as root:
--wget -O - http://www.reinholdtsen.name/freedombox/BE1A583D.asc | \ - apt-key add - -apt-get update -apt-get install freedombox-setup -/usr/lib/freedombox/setup -
-- Reboot into your freshly created Freedombox. - -
You can test it on other architectures too, but because the -freedombox-privoxy package is binary, it will only work as intended on -the architectures where I have had time to build the binary and put it -in my APT repository. But do not let this stop you. It is only a -short "apt-get source -b freedombox-privoxy" away. :)
- -Note that by default Freedombox is a DHCP server on the -192.168.1.0/24 subnet, so if this is your subnet be careful and turn -off the DHCP server by running "update-rc.d isc-dhcp-server -disable" as root.
- -Please let me know if this works for you, or if you have any -problems. We gather on the IRC channel -#freedombox on -irc.debian.org and the -project -mailing list.
- -Once you get your freedombox operational, you can visit -http://your-host-name:8001/ to see the state of the plint -welcome screen (dead end - do not be surprised if you are unable to -get past it), and next visit http://your-host-name:8001/help/ -to look at the rest of plinth. The default user is 'admin' and the -default password is 'secret'.
+ +Jeg har fortsatt behov for å kunne laste ned innslag fra NRKs +nettsted av og til for å se senere når jeg ikke er på nett, men +min +oppskrift fra 2011 sluttet å fungere da NRK byttet +avspillermetode. I dag fikk jeg endelig lett etter oppdatert løsning, +og jeg er veldig glad for å fortelle at den enkleste måten å laste ned +innslag er å bruke siste versjon 2014.06.07 av +youtube-dl. Støtten i +youtube-dl kom +inn for 23 dager siden og +versjonen i +Debian fungerer fint også som backport til Debian Wheezy. Det er +et lite problem, det håndterer kun URLer med små bokstaver, men hvis +en har en URL med store bokstaver kan en bare gjøre alle store om til +små bokstaver for å få youtube-dl til å laste ned. Rapporterte +nettopp +problemet til +utviklerne, og antar de får fikset det snart.
+ +Dermed er alt klart til å laste ned dokumentarene om +USAs +hemmelige avlytting og +Selskapene +bak USAs avlytting, i tillegg til +intervjuet +med Edward Snowden gjort av den tyske tv-kanalen ARD. Anbefaler +alle å se disse, sammen med +foredraget +til Jacob Appelbaum på siste CCC-konferanse, for å forstå mer om +hvordan overvåkningen av borgerne brer om seg.
+ +Takk til gode venner på foreningen NUUGs IRC-kanal +#nuug på irc.freenode.net +for tipsene som fikk meg i mål.
+ +Oppdatering 2014-06-17: Etter at jeg publiserte +denne, ble jeg tipset om bloggposten +"Downloading +HD content from tv.nrk.no" av Ingvar Hagelund, som har alternativ +implementasjon og tips for å lage mkv-fil med undertekstene inkludert. +Kanskje den passer bedre for deg? I tillegg ble feilen i youtube-dl +ble fikset litt senere ut på dagen i går, samt at youtube-dl fikk +støtte for å laste ned undertitler. Takk til Anders Einar Hilden for +god innsats og youtube-dl-utviklerne for rask respons.
I 2011 raderte et stortingsflertall bestående av Høyre og -Arbeiderpartiet vekk en betydelig del av privatsfæren til det norske -folk. Det ble vedtatt at det skulle registreres og lagres i et halvt -år hvor alle som bærer på en mobiltelefon befinner seg, hvem de -snakker med og hvor lenge de snakket sammen. Det skal også -registreres hvem de sendte SMS-meldinger til, hvem en har sendt epost -til, og hvilke nett-tjenere en besøkte. Saken er kjent som -Datalagringsdirektivet -(DLD), og innebærer at alle innbyggerne og andre innenfor Norges -grenser overvåkes døgnet rundt. Det ble i praksis innført brev og -besøkskontroll av hele befolkningen. Rapporter fra de landene som -allerede har innført slik total lagring av borgernes -kommunikasjonsmønstre forteller at det ikke hjelper i -kriminalitetsbekjempelsen. Den norske prislappen blir mange hundre -millioner, uten at det ser ut til å bidra positivt til politiets -arbeide. Jeg synes flere hundre millioner i stedet burde vært brukt -på noe som kan dokumenteres å ha effekt i kriminalitetsbekjempelsen. -Se mer på -Wikipedia -og Jon Wessel-Aas.
- -Hva er problemet, tenkter du kanskje? Et åpenbart problem er at -medienes kildevern i praksis blir radert ut. Den innsamlede -informasjonen gjør det mulig å finne ut hvem som har snakket med -journalister på telefon, SMS og epost, og hvem som har vært i nærheten -av journalister så sant begge bar med seg en telefon. Et annet er at -advokatvernet blir sterkt redusert, der politiet kan finne ut hvem -som har snakket med en advokat når, eller vært i møter en med advokat. -Et tredje er at svært personlig informasjon kan avledes fra hvilke -nettsteder en har besøkt. Har en besøkt hivnorge.no, -swingersnorge.com eller andre sider som kan brukes til avlede -interesser som hører til privatsfæren, vil denne informasjonen være -tilgjengelig takket være datalagringsdirektivet.
- -De fleste partiene var mot, kun to partier stemte for. Høyre og -Arbeiderpartiet. Og både Høyre og Arbeiderpartiet i Oslo har -DLD-forkjempere på toppen av sine lister (har ikke sjekket de andre -fylkene). Det er dermed helt uaktuelt for meg å stemme på disse -partiene. Her er oversikten over partienes valglister i Oslo, med -informasjon om hvem som stemte hva i første DLD-votering i Stortinget, -basert på informasjon fra mine venner i -Holder de -Ord samt data.stortinget.no. -Først ut er stortingslista fra Høyre for Oslo:

The second wheezy based beta release of Debian Edu was wrapped up -today, slightly delayed because of some bugs in the initial Windows -integration fixes . This is the release announcement:
- -New features for Debian Edu 7.1+edu0~b1 released 2013-08-22
- -These are the release notes for Debian Edu / Skolelinux -7.1+edu0~b1, based on Debian with codename "Wheezy".
- -About Debian Edu and Skolelinux
- -Debian Edu, also known as -Skolelinux, is a Linux distribution based on Debian providing an -out-of-the box environment of a completely configured school -network. Immediately after installation a school server running all -services needed for a school network is set up just waiting for users -and machines being added via GOsa², a comfortable Web-UI. A netbooting -environment is prepared using PXE, so after initial installation of -the main server from CD or USB stick all other machines can be -installed via the network. The provided school server provides LDAP -database and Kerberos authentication service, centralized home -directories, DHCP server, web proxy and many other services. The -desktop contains -more -than 60 educational software packages and more are available from -the Debian archive, and schools can choose between KDE, Gnome, LXDE -and Xfce desktop environment.
- -This is the sixth test release based on Debian Wheezy. Basically this -is an updated and slightly improved version compared to the Squeeze -release.
- -ALERT: Alpha based installations should reinstall or downgrade the -versions of gosa and libpam-mklocaluser to the ones used in this beta -release. Both alpha and beta0 based installations should reinstall or -deal with gosa.conf manually; there are two options: (1) Keep -gosa.conf and edit this file as outlined -on -the mailing list. (2) Accept the new version of gosa.conf and -replace both contained admin password placeholders with the password -hashes found in the old one (backup copy!). In both cases every user -need to change their their password to make sure a password is set for -CIFS access to their home directory.
- -Software updates
- --
-
-
- Added ssh askpass packages to default installation, to ensure ssh - work also without a attached tty. -
- Add the command-not-found package to the default installation to - make it easier to figure out where to find missing command line - tools. Please note, that the command 'update-command-not-found' - has to be run as root to actually make it useful (internet access - required). - -
Other changes
- --
-
-
- Adjusted the USB stick ISO image build to include every tool -needed for desktop=xfce installations. -
- Adjust thin-client-server task to work when installing from USB -stick ISO image. -
- Made new grub artwork (changed png from indexed to RGB format). -
- Minor cleanup in the CUPS setup. -
- Make sure that bootstrapping of the Samba domain really happens - during installation of the main server and adjust SID handling to - cope with this. -
- Make Samba passwords changeable (again) via GOsa². -
- Fix generation of LM and NT password hashes via GOsa² to avoid - empty password hashes. -
- Adapted Samba machine domain joining to latest change in the - smbldap-tools Perl package, fixing bugs blocking Windows machines - from joining the Samba domain. - -
Known issues
- --
-
-
- KDE fails to understand the wpad.dat file provided, causing it to - not use the http proxy as it should. -
- Chromium also fails to use the proxy when using the KDE desktop - (using the KDE configuration). - -

How to report bugs
- -http://wiki.debian.org/DebianEdu/HowTo/ReportBugs +
+I've been following the Gnash +project for quite a while now. It is a free software +implementation of Adobe Flash, both a standalone player and a browser +plugin. Gnash implement support for the AVM1 format (and not the +newer AVM2 format - see +Lightspark for that one), +allowing several flash based sites to work. Thanks to the friendly +developers at Youtube, it also work with Youtube videos, because the +Javascript code at Youtube detect Gnash and serve a AVM1 player to +those users. :) Would be great if someone found time to implement AVM2 +support, but it has not happened yet. If you install both Lightspark +and Gnash, Lightspark will invoke Gnash if it find a AVM1 flash file, +so you can get both handled as free software. Unfortunately, +Lightspark so far only implement a small subset of AVM2, and many +sites do not work yet.
+ +A few months ago, I started looking at +Coverity, the static source +checker used to find heaps and heaps of bugs in free software (thanks +to the donation of a scanning service to free software projects by the +company developing this non-free code checker), and Gnash was one of +the projects I decided to check out. Coverity is able to find lock +errors, memory errors, dead code and more. A few days ago they even +extended it to also be able to find the heartbleed bug in OpenSSL. +There are heaps of checks being done on the instrumented code, and the +amount of bogus warnings is quite low compared to the other static +code checkers I have tested over the years.
+ +Since a few weeks ago, I've been working with the other Gnash +developers squashing bugs discovered by Coverity. I was quite happy +today when I checked the current status and saw that of the 777 issues +detected so far, 374 are marked as fixed. This make me confident that +the next Gnash release will be more stable and more dependable than +the previous one. Most of the reported issues were and are in the +test suite, but it also found a few in the rest of the code.
+ +If you want to help out, you find us on +the +gnash-dev mailing list and on +the #gnash channel on +irc.freenode.net IRC server.
Earlier, I reported about -my -problems using an Intel SSD 520 Series 180 GB disk. Friday I was -told by IBM that the original disk should be thrown away. And as -there no longer was a problem if I bricked the firmware, I decided -today to try to install Intel firmware to replace the Lenovo firmware -currently on the disk.
- -I searched the Intel site for firmware, and found -issdfut_2.0.4.iso -(aka Intel SATA Solid-State Drive Firmware Update Tool) which -according to the site should contain the latest firmware for SSD -disks. I inserted the broken disk in one of my spare laptops and -booted the ISO from a USB stick. The disk was recognized, but the -program claimed the newest firmware already were installed and refused -to insert any Intel firmware. So no change, and the disk is still -unable to handle write load. :( I guess the only way to get them -working would be if Lenovo releases new firmware. No idea how likely -that is. Anyway, just blogging about this test for completeness. I -got a working Samsung disk, and see no point in spending more time on -the broken disks.
+ +It would be nice if it was easier in Debian to get all the hardware +related packages relevant for the computer installed automatically. +So I implemented one, using +my Isenkram +package. To use it, install the tasksel and isenkram packages and +run tasksel as user root. You should be presented with a new option, +"Hardware specific packages (autodetected by isenkram)". When you +select it, tasksel will install the packages isenkram claim is fit for +the current hardware, hot pluggable or not.
+ +
The implementation is in two files, one is the tasksel menu entry +description, and the other is the script used to extract the list of +packages to install. The first part is in +/usr/share/tasksel/descs/isenkram.desc and look like +this:
+ ++ ++Task: isenkram +Section: hardware +Description: Hardware specific packages (autodetected by isenkram) + Based on the detected hardware various hardware specific packages are + proposed. +Test-new-install: mark show +Relevance: 8 +Packages: for-current-hardware +
The second part is in +/usr/lib/tasksel/packages/for-current-hardware and look like +this:
+ ++ ++#!/bin/sh +# +( + isenkram-lookup + isenkram-autoinstall-firmware -l +) | sort -u +
All in all, a very short and simple implementation making it +trivial to install the hardware dependent package we all may want to +have installed on our machines. I've not been able to find a way to +get tasksel to tell you exactly which packages it plan to install +before doing the installation. So if you are curious or careful, +check the output from the isenkram-* command line tools first.
+ +The information about which packages are handling which hardware is +fetched either from the isenkram package itself in +/usr/share/isenkram/, from git.debian.org or from the APT package +database (using the Modaliases header). The APT package database +parsing have caused a nasty resource leak in the isenkram daemon (bugs +#719837 and +#730704). The cause is in +the python-apt code (bug +#745487), but using a +workaround I was able to get rid of the file descriptor leak and +reduce the memory leak from ~30 MiB per hardware detection down to +around 2 MiB per hardware detection. It should make the desktop +daemon a lot more useful. The fix is in version 0.7 uploaded to +unstable today.
+ +I believe the current way of mapping hardware to packages in +Isenkram is is a good draft, but in the future I expect isenkram to +use the AppStream data source for this. A proposal for getting proper +AppStream support into Debian is floating around as +DEP-11, and +GSoC +project will take place this summer to improve the situation. I +look forward to seeing the result, and welcome patches for isenkram to +start using the information when it is ready.
+ +If you want your package to map to some specific hardware, either +add a "Xb-Modaliases" header to your control file like I did in +the pymissile +package or submit a bug report with the details to the isenkram +package. See also +all my +blog posts tagged isenkram for details on the notation. I expect +the information will be migrated to AppStream eventually, but for the +moment I got no better place to store it.
