Frikanalen - Complete TV station organised using the web
-
3rd March 2013
-

Do you want to set up your own TV station, schedule videos and -broadcast them on the air? Using free software? With video on demand -support using -free and -open standards? Included a web based video stream as well? And -administrate it all in your web browser from anywhere in the world? A -few years now the Norwegian public access TV-channel -Frikanalen have been building a -system to do just this. The source code for the solution is licensed -using the GNU LGPL, and -available from github.

- -

The idea is simple. You upload a video file over the web, and -attach meta information to the file. You select a time slot in the -program schedule, and when the time come it is played on the air and -in the web stream. It is also made available in a video on demand -solution for anyone to see it also outside its scheduled time. All -you need to run a TV station - using your web browser.

- -

There are several parts to this web based solution. I'll mention -the three most important ones. The first part is the database of -videos and the schedule. This is written in Django and include a REST -API. The current database is SQLite, but the plan is to migrate it to -PostgreSQL. At the moment this system can be tested on -beta.frikanalen.tv. The -second part is the video playout, taking the schedule information from -the database and providing a video stream to broadcast. This is done -using CasparCG from SVT and -Media Lovin' Toolkit. Video -signal distribution is handled using -Open Broadcast Encoder. The -third part is the converter, handling the transformation of uploaded -video files to a format useful for broadcasting, streaming and video -on demand. It is still very much work in progress, so it is not yet -decided what it will end up using. Note that the source of the latter -two parts are not yet pushed to github. The lead author want to clean -them up a bit more first.

- -

The development is coordinated on the -#frikanalen IRC -channel (irc.freenode.net), and discussed on -the -frikanalen mailing list. The lead developer is Benjamin Bruheim -(phed on IRC). Anyone is welcome to participate in the -development.

Good causes: Debian Outreach Program for Women, EFF documenting the spying and Open access in Norway
+
15th October 2013
+

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.

Dr. Richard Stallman, founder of Free Software Foundation, give a talk in Oslo March 1st 2013
-
27th February 2013
-

Dr. Richard Stallman, -founder of Free Software Foundation, -is giving a -talk in Oslo March 1st 2013 17:00 to 19:00. The event is public -and organised by Norwegian Unix Users Group (NUUG) -(where I am the chair of the board) and -The Norwegian Open Source Competence -Center. The title of the talk is «The Free Software Movement and -GNU», with this description: - -

-The Free Software Movement campaigns for computer users' freedom to -cooperate and control their own computing. The Free Software Movement -developed the GNU operating system, typically used together with the -kernel Linux, specifically to make these freedoms possible. -

- -

The meeting is open for everyone. Due to space limitations, the -doors opens for NUUG members at 16:15, and everyone else at 16:45. I -am really curious how many will show up. See -the event -page for the location details.

Oslo community mesh network - with NUUG and Hackeriet at Hausmania
+
11th October 2013
+

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:

+ +

+ + + + + +
SettingValue
Protocol / kernel modulebatman-adv
ESSIDmeshfx@hackeriet
Channel / Frequency11 / 2462
Cell ID02: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.

Skolelinux-intervju: Helge Tore Høyland
-
22nd February 2013
-

Etter en lang pause og travle uker har jeg endelig klart å få -samlet et nytt intervju med en av folkene i -Skolelinux-miljøet. -Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på -epostlistene og ellers i prosjektet.

- -

Hvem er du, og hva driver du med til daglig?

- -

Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn -Uno IT. Uno IT er eit lite firma som -drifter nettverk og maskiner for små og mellomstore firma -Steinkjer-området. Per dags dato er me 2 ansatte. Min faglege bakgrunn -er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og -server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye -maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit -vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux -har eg hatt i forbindelse med drifting av -Bjørkly skule, ein privat -grunnskule i Namsos-området. I dag har skulen 65 elever, 15 lærere, 1 -hovedserver og ca 60 klienter som kjører halvtjukt. Eg har bygd og -driftet systemet sidan summaren 2006.

- -

Hvordan kom du i kontakt med Skolelinux-prosjektet?

- -

Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit -fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie -hadde pusla med nettverk for ein annan skule, fatta eg straks -interesse for prosjektet.

- -

Hva er fordelene med Skolelinux slik du ser det?

- -

Fordelane med Skolelinux er sentralisert administrasjon og svært -mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte 60 -klientar med berre å «bry» seg med ein server. Levetid for systemets -hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt -sikkerhet og mindre lisenskostnader. Etter min erfaring er det og -mykje mindre driftskostnader med eit slikt system enn konkurrerande -system, pga enkelhet med sentralisert administrasjon. På grunn av at -Skolelinux er basert på Debian er det òg svært stabilt.

- -

Hva er ulempene med Skolelinux slik du ser det?

- -

Ulemper er mangel på vilje til å følge standarer ute i markedet, -som fører til mangel på støtte til nokre mykje brukte ting. Flash og -Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å -ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti -at program vert «for gamle». Det er spesielt nettlesaren som er -utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg, -for «alle» platformer fører òg til noko hovudbry.

- -

Hvilken fri programvare bruker du til daglig?

- -

Til dagleg bruker eg svært mange forskjellige «fri programvare» -program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla, -OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.

- -

Hvilken strategi tror du er den rette å bruke for å få -skoler til å ta i bruk fri programvare?

- -

Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så -fokusert på at det er fri programvare men at det skal «berre fungere». -Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux -sin del må ein få eit betre fokus på overganger. Utbytting av servere -må gå meir automatisk, import og eksport av brukerbase og maskinbase -med meir må kunne gå enkelt og oppgradering til neste versjon må bli -mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette -opp frå start når ein byter ut ein server eller oppgraderer til neste -versjon. For å få Skolelinux til å bli eit betre alternativ for skular -må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte -dei protokollar og tillegg som vert brukt av forlag med meir. Etter -kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og -viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i -bruk opne standarer, men inntil det skjer, må systemet kunne brukast -mot desse fagsystema.

- -

For meg har prosjektet med Skolelinux vore ein svært artig og -lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok, -men det er svært hjelpevillig og engasjert.

Skolelinux / Debian Edu 7.1 install and overview video from Marcelo Salvador
+
8th October 2013
+

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).

"Electronic" paper invoices - using vCard in a QR code
-
12th February 2013
-

Here in Norway, electronic invoices are spreading, and the -solution promoted -by the Norwegian government require that invoices are sent through -one of the approved facilitators, and it is not possible to send -electronic invoices without an agreement with one of these -facilitators. This seem like a needless limitation to be able to -transfer invoice information between buyers and sellers. My preferred -solution would be to just transfer the invoice information directly -between seller and buyer, for example using SMTP, or some HTTP based -protocol like REST or SOAP. But this might also be overkill, as the -"electronic" information can be transferred using paper invoices too, -using a simple bar code. My bar code encoding of choice would be QR -codes, as this encoding can be read by any smart phone out there. The -content of the code could be anything, but I would go with -the vCard format, as -it too is supported by a lot of computer equipment these days.

- -

The vCard format support extentions, and the invoice specific -information can be included using such extentions. For example an -invoice from SLX Debian Labs (picked because we -ask -for donations to the Debian Edu project and thus have bank account -information publicly available) for NOK 1000.00 could have these extra -fields:

- -

-X-INVOICE-NUMBER:1
-X-INVOICE-AMOUNT:NOK1000.00
-X-INVOICE-KID:123412341234
-X-INVOICE-MSG:Donation to Debian Edu
-X-BANK-ACCOUNT-NUMBER:16040884339
-X-BANK-IBAN-NUMBER:NO8516040884339
-X-BANK-SWIFT-NUMBER:DNBANOKKXXX
-

- -

The X-BANK-ACCOUNT-NUMBER field was proposed in a stackoverflow -answer regarding -how -to put bank account information into a vCard. For payments in -Norway, either X-INVOICE-KID (payment ID) or X-INVOICE-MSG could be -used to pass on information to the seller when paying the invoice.

- -

The complete vCard could look like this:

- -

-BEGIN:VCARD
-VERSION:2.1
-ORG:SLX Debian Labs Foundation
-ADR;WORK:;;Gunnar Schjelderups vei 29D;OSLO;;0485;Norway

-X-BANK-IBAN-NUMBER:NO8516040884339
-X-BANK-SWIFT-NUMBER:DNBANOKKXXX
-END:VCARD
-

- -

The resulting QR code created using -qrencode would look -like this, and should be readable (and thus checkable) by any smart -phone, or for example the zbar -bar code reader and feed right into the approval and accounting -system.

- -

- -

The extension fields will most likely not show up in any normal -vCard reader, so those parts would have to go directly into a system -handling invoices. I am a bit unsure how vCards without name parts -are handled, but a simple test indicate that this work just fine.

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.

+ + +

cheers, +

Sleep until morning - home automation for the kids
-
10th February 2013
-

- -

With kids in the house, one challenge is getting them to sleep -during the night and wake up when it is morning. I mean, when I -believe it is morning, and not two hours earlier. In our household we -have decided that 07:00 is the turning point, but getting the kids to -sleep until 07:00 is a small challenge every day. They have adapted -quite well, and rarely wake up at 05:00 any more, but some times wake -up at times like 05:50, 06:15, 06:30 or 06:45, and it is hard to put -the awake one to bed again without disturbing and waking the rest. -And I understand perfectly well that they fail to sleep until 07:00 -some times, as there is no way for them to know if it is before or -after the magic moment without coming and asking us parents.

- -

But yesterday I came up with a method to solve this problem. It -involve home automation. A few years ago I bought a -Tellstick and RF -switches at the local Clas -Ohlson shop, allowing me to control lights and other electrical -gadgets using my Linux server. When I moved from the old flat to a -small house, I put away all this equipment as most of the lighting in -the house was not using wall sockets and thus not easy to connect to -the gadgets I had. But recently I bought a -Tellstick -Net to be able to read sensor input as well as control power -sockets. I want to control ovens in the basement to avoid the pipes -to freeze, and monitor the humidity to detect flooding. The default -setup for Tellstick Net is to be controlled by the vendor web service, -which to me is a security problem, but it is also possible to build -ones own -firmware -with local access instead of being controlled by a Swedish -company, thanks to the release of the GPL licensed firmware source -code. I plan to get that running before I let it control anything -important. But while working on this, one idea to make it easier for -the kids came to me yesterday. We can set up a night light controlled -by the computer, and turn it automatically on at 07:00. The kids can -then check the light in the morning to know if they are supposed to -get up or not. They joined me in setting everything up, and I -repeated the concept several times before bed times to make sure they -remembered to check the light before getting up in the morning.

- -

We tested it this morning, and all the kids stayed in bed until -after 07:00, and every one of them commented on the fact that the -"morning light" was turned on and signalled that the morning had -arrived. So this look like a success, and I am excited to see how -this develops the next few days. :) I really hope this can allow us -all to sleep a bit longer in the morning.

- -

A nice advantage of this setup is that we can remote control when -to tell the kids to get up. We do not have to wait until 07:00, and -can also delay it if we want to.

Recipe to test the Freedombox project on amd64 or Raspberry Pi
+
10th September 2013
+

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

+ +
    + +
  1. Fetch normal Debian Wheezy installation ISO.
    2. +
  2. Boot from it, either as CD or USB stick.
    3. +

  3. 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
    4. + +
  4. Answer the few language/region/password questions and pick disk to +install on.
    5. + +
  5. When the installation is finished and the machine have rebooted a +few times, your Freedombox is ready for testing.
    6. + +
+ +

Raspberry Pi Raspbian

+ +
    + +
  1. Fetch a Raspbian SD card image, create SD card.
    2. +
  2. Boot from SD card, extend file system to fill the card completely.
    3. +

  3. Log in and add this to /etc/sources.list:

    +
    +deb http://www.reinholdtsen.name/freedombox wheezy main
+
    4. +

  4. 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
+
    5. +
  5. Reboot into your freshly created Freedombox.
    6. + +
+ +

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'.

Hva stemte hver stortingsrepresentant i voteringene om datalagringsdirektivet?
-
9th February 2013

Nytt stortingsvalg er på trappene, og folket får igjen mulighet til -å påvirke sammensetningen i vår lovgivende forsamling.

Datalagringsdirektivet gjør at Oslo Høyre og Arbeiderparti ikke får min stemme i år
+
8th September 2013
+

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:

Økt overvåkning applauderes igjen av Arbeiderpartiet, Høyre og Fremskrittspartiet

Second beta release (beta 1) of Debian Edu/Skolelinux based on Debian Wheezy
+
22nd August 2013
+

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).

Bitcoin GUI now available from Debian/unstable (and Ubuntu/raring)
-
2nd February 2013
-

My -last -bitcoin related blog post mentioned that the new -bitcoin package for -Debian was waiting in NEW. It was accepted by the Debian ftp-masters -2013-01-19, and have been available in unstable since then. It was -automatically copied to Ubuntu, and is available in their Raring -version too.

- -

But there is a strange problem with the build that block this new -version from being available on the i386 and kfreebsd-i386 -architectures. For some strange reason, the autobuilders in Debian -for these architectures fail to run the test suite on these -architectures (BTS #672524). -We are so far unable to reproduce it when building it manually, and -no-one have been able to propose a fix. If you got an idea what is -failing, please let us know via the BTS.

- -

One feature that is annoying me with of the bitcoin client, because -I often run low on disk space, is the fact that the client will exit -if it run short on space (BTS -#696715). So make sure you have enough disk space when you run -it. :)

As usual, if you use bitcoin and want to show your support of my -activities, please send Bitcoin donations to my address -15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b.

Intel 180 SSD disk with Lenovo firmware can not use Intel firmware
+
18th August 2013
+

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.
