RAND terms - non-reasonable and discriminatory
-
19th April 2012
-

Here in Norway, the - Ministry of -Government Administration, Reform and Church Affairs is behind -a directory of -standards that are recommended or mandatory for use by the -government. When the directory was created, the people behind it made -an effort to ensure that everyone would be able to implement the -standards and compete on equal terms to supply software and solutions -to the government. Free software and non-free software could compete -on the same level.

- -

But recently, some standards with RAND -(Reasonable -And Non-Discriminatory) terms have made their way into the -directory. And while this might not sound too bad, the fact is that -standard specifications with RAND terms often block free software from -implementing them. The reasonable part of RAND mean that the cost per -user/unit is low,and the non-discriminatory part mean that everyone -willing to pay will get a license. Both sound great in theory. In -practice, to get such license one need to be able to count users, and -be able to pay a small amount of money per unit or user. By -definition, users of free software do not need to register their use. -So counting users or units is not possible for free software projects. -And given that people will use the software without handing any money -to the author, it is not really economically possible for a free -software author to pay a small amount of money to license the rights -to implement a standard when the income available is zero. The result -in these situations is that free software are locked out from -implementing standards with RAND terms.

- -

Because of this, when I see someone claiming the terms of a -standard is reasonable and non-discriminatory, all I can think of is -how this really is non-reasonable and discriminatory. Because free -software developers are working in a global market, it does not really -help to know that software patents are not supposed to be enforceable -in Norway. The patent regimes in other countries affect us even here. -I really hope the people behind the standard directory will pay more -attention to these issues in the future.

Gatemagasinet =Oslo får konkurrent fra Folk er Folk
+
19th June 2012
+

Aftenposten melder i dag at selgerne av +gatemagasinet =Oslo er +irritert +på at det er kommet en konkurrent på banen fra organisasjonen +Folk er Folk, +som støtter “rumenerne”, de mest uglesette av tiggerne i Norge. Min +første tanke da jeg leste nyheten er at slik må =Oslo-selgerne tåle +når de nekter "rumenerne" og andre utenlandske tiggere å selge +gatemagasinet sitt. Det ble rapportert for noen år siden at +utenlandske +tiggere ikke var velkomne som selgere, og å opprette en konkurrent +virker da for meg som et rasjonelt alternativ. Og at "rumerene" +utelukkes gjelder visst ikke bare i Oslo. I Adresseavisen fant jeg en +artikkel om at selgerne av +gateavisen +Sorgenfri i Trondheim også +utelukker +utenlandske selgere.

+ +

Men situasjonen er visst ikke så rett frem som opprinnelige +artikler kunne tyde på. Mens jeg søkte opp gamle artikler og +referanser om temaet, fant jeg et +leserbrev +fra en av stifterne av =Oslo, som protesterte på +påstander +fra likestillingsombudet om diskriminering og forteller at =Oslo +krever at de som selger magasinet skal kunne kommunisere med kundene +for å kunne representere magasinet utad, og at "rumererne" ikke +ekskluderes for å være utlendinger men pga. at de ikke kan snakke +norsk. Det er jo ikke urimelig å kreve at en selger skal kunne +kommunisere med kundene, men som kjøper har jeg ikke snakket så mye +med =Oslo-selgerne at det ville vært et problem for meg om selgeren +ikke kunne snakke norsk. Jeg er dermed i tvil om hvorvidt +argumentasjonen holder når effekten er at de mest uglesette tiggerne i +Norge ekskluderes.

+ +

Uansett tror jeg ikke markedet for gatemagasiner i Oslo er mettet. +Personlig kunne jeg godt tenkte meg å kjøpe flere, men gidder ikke +kjøpe den samme utgaven av =Oslo flere ganger. En konkurrent som Folk +er Folk kan dermed ende opp med å gjøre markedet større i stedet for å +spise av markedsandelene til =Oslo.

Forskning: "GPL gir lokal frihet og kontroll gjennom omfordeling av makt fra produsent til bruker"
-
15th April 2012
-

Da jeg googlet etter noe annet kom jeg tilfeldigvis over -en -hovedfagsoppgave ved Universitetet i Oslo som diskuterer verdien -av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert -over det som presenteres der. Her er sammendraget:

SQL-database med anbud publisert på Doffin
+
15th June 2012
+

Doffin er det offentlige Norges +portal for annonsering av anbudsutlysninger. Nettstedet er mye brukt, +men rådataene er ikke enkelt tilgjengelig for almenheten. For å bøte +på det har jeg som et NUUG-prosjekt +laget en Scraperwiki-skraper som +lager en +SQL-database +med nøkkelinformasjonen fra Doffin, slik at det er mulig å søke og +analysere Doffin-oppføringene. Det publiseres mellom 900-1500 anbud +hver måned via Doffin. Jeg har ingen konkrete planer for analyse, men +håper enklere tilgjengelighet gjør at flere griper sjansen. På sikt +håper jeg å bruke denne databasen som grunnlag for å lage en database +over anbudsdokumenter, som i dag ikke er tilgjengelig fra doffin, men +må bestilles fra hver enkelt utlyser.

+ +

Jeg var litt usikker på om det var rettighetsproblemer knyttet til +skraping av informasjon fra Doffin, men ser i +vilkårene til +Doffin følgende:

-

Motivasjonen til å skrive denne oppgaven er en personlig undring -over hvorfor det primært, og ofte eksklusivt, fokuseres på det -økonomiske aspektet ved utredninger om fri programvare er et godt valg -for det offentlige. Fri og produsenteid programvare bygger på -fundamentalt forskjellige ideologier som kan ha implikasjoner utover -økonomiske kostnader. Kunnskapskulturen som er med på å definere fri -programvare er basert på åpenhet, og er en verdi i seg selv.

- -

Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert -programvare gir visse friheter i forhold til produsenteid -programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning, -disse frihetene blir benyttet av ulike brukere og hvordan de -manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven -er:

+

Opphavsrett mv

-
    -
  • Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
    • -
  • Hvilke konsekvenser har programvarelisensen for de ulike brukere?
    • -
+

Ved innleggig av kunngjøringer på Doffin aksepterer Oppdragsgiver +at opphavsrett og andre rettigheter til materialet overføres til +Fornyings- og administrasjonsdepartementet, eller den departementet +utnevner. Oppdragsgiver har imidlertid bruksrett til materialet, og +kan benytte det til de formål de måtte ønske.

-

Fri programvare gir blant annet brukeren mulighet til å studere og -modifisere kildekoden. Denne formen for frihet erverves gjennom -kunnskap og krever at brukeren også er en ekspert. Hva skjer med -frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i -dialog med informantene.

- -

Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige -ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen -for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus -fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske -delen av oppgaven er delt inn i to seksjoner; den første omhandler -operativsystemet Skolelinux, den andre kontorprogrampakken -OpenOffice.org.

- -

Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling -av makt fra produsent til bruker. Brukerens makt analyseres gjennom -begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt -vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de -økonomiske begrepene nettverkseksternaliteter, innlåsing og -stiavhengighet. Dette er begreper av spesiell nytte når objektet som -omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien -til et slikt gode for en potensiell bruker avhenger av antall -eksisterende brukere av godet. I tilknytning til denne problematikken -inneholder oppgaven også en diskusjon rundt åpne standarder og -formater.

- -

Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er -laget for å beskytte er av avgjørende betydning for bruken av -OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i -skolene i Nittedal. Distribusjonen av handlekraft er ikke helt -symmetrisk. Det er først og fremst de profesjonelle utviklerne i -Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode, -mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske -friheten til å kunne distribuere programmene. Det er imidlertid også -slik at ingen aktør klarer seg uten alle disse «frihetene».

-

Jeg fant også en masteroppgave fra 2006, men der ligger ikke -komplett oppgave tilgjengelig. På tide å holde et øye med -Skolelinux-søket -til DUO...

- +

Hvis informasjonen er vernet av opphavsrettsloven (hvilket jeg +tviler på, gitt lovens begrensninger om informasjon fra det +offentlige), så er det FAD som har de immaterielle rettighetene. FAD +er en del av staten, som opererer på vegne av folket, og enhver borger +skulle dermed ha rett til å videreformidle informasjonen. Ingen av +offentlighetslovens unntak kommer til anvendelse, i og med at +informasjonen allerede er publisert.

Debian Edu interview: Andreas Mundt
-
15th April 2012
-

Behind Debian Edu and -Skolelinux there are a lot of people doing the hard work of -setting together all the pieces. This time I present to you Andreas -Mundt, who have been part of the technical development team several -years. He was also a key contributor in getting GOsa and Kerberos set -up in the recently released -Debian -Edu Squeeze version.

- -

Who are you, and how do you spend your days?

- -

My name is Andreas Mundt, I grew up in south Germany. After -studying Physics I spent several years at university doing research in -Quantum Optics. After that I worked some years in an optics company. -Finally I decided to turn over a new leaf in my life and started -teaching 10 to 19 years old kids at school. I teach math, physics, -information technology and science/technology.

- -

How did you get in contact with the Skolelinux/Debian Edu -project?

- -

Already before I switched to teaching, I followed the Debian Edu -project because of my interest in education and Debian. Within the -qualification/training period for the teaching, I started -contributing.

Debian Edu - some ideas for the future versions
+
11th June 2012
+

During my work on +Debian Edu +based on Squeeze, I came across some issues that should be +addressed in the Wheezy release. I finally found time to wrap up my +notes and provide quick summary of what I found, with a bit +explanation.

-

What do you see as the advantages of Skolelinux/Debian -Edu?

+

    -

    The advantages of Debian Edu are the well known name, the -out-of-the-box philosophy and of course the great free software of the -Debian Project!

    +
  • We need to rewrite our package installation framework, as tasksel +changed from using tasksel tasks to using meta packages (aka packages +with dependencies like our education-* packages), and our installation +system depend on tasksel tasks in +/usr/share/tasksel/debian-edu-tasks.desc for package +installation.
    • + +
  • Enable Kerberos login for more services. Now with the Kerberos +foundation in place, we should use it to get single sign on with more +services, and avoiding unneeded password / login questions. We should +at least try to enable it for these services: +
      -

      What do you see as the disadvantages of Skolelinux/Debian -Edu?

      +
    • CUPS for admins to add/configure printers and users when using + quotas.
      • +
    • Nagios for admins checking the system status.
      • +
    • GOsa for admins updating LDAP and users changing their passwords.
      • +
    • LDAP for admins updating LDAP.
      • +
    • Squid for users when exam mode / filtering is active.
      • +
    • ssh for admins and users to save a password prompt.
      • -

      As every coin has two sides, the out-of-the-box philosophy has its -downside, too. In my opinion, it is hard to modify and tweak the -setup, if you need or want that. Further more, it is not easily -possible to upgrade the system to a new release. It takes much too -long after a Debian release to prepare the -Edu release, perhaps -because the number of developers working on the core of the code is -rather small and often busy elsewhere.

      +
    • -

    The Debian LAN -project might fill the use case of a more flexible system.

    +
  • When we move GOsa to use Kerberos instead of LDAP bind to +authenticate users, we should try to block or at least limit access to +use LDAP bind for authentication, to ensure Kerberos is used when it +is intended, and nothing fall back to using the less safe LDAP bind
    • + +
  • Merge debian-edu-config and debian-edu-install. The split made +sense when d-e-install did a lot more, but these days it is just an +inconvenience when we update the debconf preseeding values.
    • + +
  • Fix partman-auto to allow us to abort the installation before +touching the disk if the disk is too small. This is +BTS report #653305 and the +d-i developers are fine with the patch and someone just need to apply +it and upload. After this is done we need to adjust +debian-edu-install to use this new hook.
    • + +
  • Adjust to new LTSP framework (boot time config instead of install +time config). LTSP changed its design, and our hooks to install +packages and update the configuration is most likely not going to work +in Wheezy. + +
  • Consider switching to NBD instead of NFS for LTSP root, to allow +the Kernel to cache files in its normal file cache, possibly speeding +up KDE login on slow networks.
    • + +
  • Make it possible to create expired user passwords that need to +change on first login. This is useful when handing out password on +paper, to make sure only the user know the password. This require +fixes to the PAM handling of kdm and gdm.
    • + +
  • Make GUI for adding new machines automatically from sitesummary. +The current command line script is not very friendly to people most +familiar with GUIs. This should probably be integrated into GOsa to +have it available where the admin will be looking for it..
    • + +
  • We should find way for Nagios to check that the DHCP service +actually is working (as in handling out IP addresses). None of the +Nagios checks I have found so far have been working for me.
    • + +
  • We should switch from libpam-nss-ldapd to sssd for all profiles +using LDAP, and not only on for roaming workstations, to have less +packages to configure and consistent setup across all profiles.
    • + +
  • We should configure Kerberos to update LDAP and Samba password +when changing password using the Kerberos protocol. The hook was +requested in BTS report +#588968 and is now available in Wheezy. We might need to write a +MIT Kerberos plugin in C to get this.
    • + +
  • We should clean up the set of applications installed by default. +
      -

      Which free software do you use daily?

      +
    • reduce the number of chemistry visualisers
      • +
    • consider dropping xpaint
      • +
    • and probably more?
      • +
    • -

    I am only using non-free software if I am forced to and run Debian -on all my machines. For documents I prefer LaTeX and PGF/TikZ, then -mutt and iceweasel for email respectively web browsing. At school I -have Arduino and Fritzing in use for a micro controller project.

    +
  • Some hardware need external firmware to work properly. This is +mostly the case for WiFi network cards, but there are some other +examples too. For popular laptops to work out of the box, such +firmware need to be installed from non-free, and we should provide +some GUI to do this. Ubuntu already have this implemented, and we +could consider using their packages. At the moment we have some +command line script to do this (one for the running system, another +for the LTSP chroot).
    • + + +
  • In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We +should extend the list to Xfce and Sugar, and preferably find a way to +install several and allow the admin or the user to select which one to +use.
    • + +
  • The golearn tool from the goplay package make it easy to check out +interesting educational packages. We should work on the package +tagging in Debian to ensure it represent all the useful educational +packages, and extend the tool to allow it to use packagekit to install +new applications with a simple mouse click.
    • + +
  • The Squeeze version got half a exam solution already in place, +with the introduction of iptable based network blocking, but for it to +be a complete exam solution the Squid proxy need to enable +filtering/blocking as well when the exam mode is enabled. We should +implement a way to easily enable this for the schools that want it, +instead of the "it is documented" method of today.
    • + +
  • A feature used in several schools is the ability for a teacher to +"take over" the desktop of individual or all computers in the room. +There are at least three implementations, +italc, +controlaula og +epoptes and we should pick one of +them and make it trivial to set it up in a school. The challenges is +how to distribute crypto keys and how to group computers in one room +and how to set up which machine/user can control the machines in a +given room.
    • + +
  • Tablets and surf boards are getting more and more popular, and we +should look into providing a good solution for integrating these into +the Debian Edu network. Not quite sure how. Perhaps we should +provide a installation profile with better touch screen support for +them, or add some sync services to allow them to exchange +configuration and data with the central server. This should be +investigated.
    • -

    Which strategy do you believe is the right one to use to -get schools to use free software?

    +

-

One of the major problems is the vendor lock-in from top to bottom: -Especially in combination with ignorant government employees and -politicians, this works out great for the "market-leader". The school -administration here in Baden-Wuerttemberg is occupied by that vendor. -Documents have to be prepared in non-free, proprietary formats. Even -free browsers do not work for the school administration. Publishers -of school books provide software only for proprietary platforms.

- -

To change this, political work is very important. Parts of the -political spectrum have become aware of the problem in the last years. -However it takes quite some time and courageous politicians to 'free' -the system. There is currently some discussion about "Open Data" and -"Free/Open Standards". I am not sure if all the involved parties have -a clue about the potential of these ideas, and probably only a -fraction takes them seriously. However it might slowly make free -software and the philosophy behind it more known and popular.

+

I guess we will discover more as we continue to work on the Wheezy +version.

Litt statistikk fra Offentlig Elektronisk postjournal

De siste månedene har jeg sammen med andre i NUUG jobbet med å +gjøre det enklere å få innsyn i offentlige dokumenter, og dette +inkluderer å gjøre postjournaler enklere tilgjengelig for maskinell +analyse og søk. I den forbindelse tok jeg i dag å tittet litt på +Offentlig Elektronisk Postjournal +(OEP), FAD/DIFIs fellesløsning for departementer og statlige +etater.

+ +

Her er antall oppføringer pr. måned det siste året, +summert +opp ved hjelp av +en +Scraperwiki-database. Merk at denne Scraperwikien har +ytelsesproblemer pga. mengden data.

Det er også interessant å se hvor ofte ulike etater sender inn sine +journaloppføringer til OEP.

Debian Edu interview: Justin B. Rye

It take all kind of contributions to create a Linux distribution -like Debian Edu / Skolelinux, -and this time I lend the ear to Justin B. Rye, who is listed as a big -contributor to the -Debian -Edu Squeeze release manual. - -

Who are you, and how do you spend your days?

- -

How did you get in contact with the Skolelinux/Debian Edu -project?

I'm neither a developer nor a Skolelinux/Debian Edu user! The only -reason my name's in the credits for the documentation is that I hang -around on debian-l10n-english waiting for people to mention things -they'd like a native English speaker to proofread... So I did a sweep -through the wiki for typos and Norglish and inconsistent spellings of -"localisation".

- -

These questions are too hard for me - I don't use it! In fact I -had hardly any contact with I.T. until long after I'd got out of the -education system.

- -

I can tell you the advantages of Debian for me though: it soaks up -as much of my free time as I want and no more, and lets me do -everything I want a computer for without ever forcing me to spend -money on the latest hardware.

- -

Which free software do you use daily?

- -

I've been using Debian since Rex; popularity-contest says the -software that I use most is xinit, xterm, and xulrunner (in other -words, I use a distinctly retro sort of desktop).

TV with face recognition, for improved viewer experience

Why the KDE menu is slow when /usr/ is NFS mounted - and a workaround
-
6th April 2012
-

Recently I have spent time with -Skolelinux Drift AS on speeding -up a Debian Edu / Skolelinux -Lenny installation using LTSP diskless workstations, and in the -process I discovered something very surprising. The reason the KDE -menu was responding slow when using it for the first time, was mostly -due to the way KDE find application icons. I discovered that showing -the Multimedia menu would cause more than 20 000 IP packages to be -passed between the LTSP client and the NFS server. Most of these were - -NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the -ping times between the client and the server were in the range 2-20 -ms, the menus would be very slow. Looking at the strace of kicker in -Lenny (or plasma-desktop i Squeeze - same problem there), I see that -the source of these NFS calls are access(2) system calls for -non-existing files. KDE can do hundreds of access(2) calls to find -one icon file. In my example, just finding the mplayer icon required -around 230 access(2) calls.

- -

The KDE code seem to search for icons using a list of icon -directories, and the list of possible directories is large. In -(almost) each directory, it look for files ending in .png, .svgz, .svg -and .xpm. The result is a very slow KDE menu when /usr/ is NFS -mounted. Showing a single sub menu may result in thousands of NFS -requests. I am not the first one to discover this. I found a -KDE bug report -from 2009 about this problem, and it is still unsolved.

- -

My solution to speed up the KDE menu was to create a package -kde-icon-cache that upon installation will look at all .desktop files -used to generate the KDE menu, find their icons, search the icon paths -for the file that KDE will end up finding at run time, and copying the -icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to -these icon files in one of the first directories where KDE will look -for them. This cut down the number of file accesses required to find -one icon from several hundred to less than 5, and make the KDE menu -almost instantaneous. I'm not quite sure where to make the package -publicly available, so for now it is only available on request.

- -

The bug report mention that this do not only affect the KDE menu -and icon handling, but also the login process. Not quite sure how to -speed up that part without replacing NFS with for example NBD, and -that is not really an option at the moment.

Web service to look up HP and Dell computer hardware support status
+
6th June 2012
+

A few days ago +I +reported how to get the support status out of Dell using an +unofficial and undocumented SOAP API, which I since have found out was +discovered +by Daniel De Marco in february. Combined with my web scraping +code for HP, Dell and IBM +from +2009, I got inspired and wrote +a +web service based on Scraperwiki to make it easy to look up the +support status and get a machine readable result back.

+ +

This is what it look like at the moment when asking for the JSON +output: + +

+% GET https://views.scraperwiki.com/run/computer-hardware-support-status/?format=json&vendor=Dell&servicetag=2v1xwn1
+supportstatus({"servicetag": "2v1xwn1", "warrantyend": "2013-11-24", "shipped": "2010-11-24", "scrapestamputc": "2012-06-06T20:26:56.965847", "scrapedurl": "http://143.166.84.118/services/assetservice.asmx?WSDL", "vendor": "Dell", "productid": ""})
+%
+
+ +

It currently support Dell and HP, and I am hoping for help to add +support for other vendors. The python source is available on +Scraperwiki and I welcome help with adding more features.

Kommentar til artikkel i Adresseavisa som omtaler FiksGataMi
+
2nd June 2012
+

Jeg oppdaget nylig en +artikkel +i Adresseavisa i Trondheim som nevner FiksGataMi, og der Trondheim +kommune ser ut til å fortelle at de ikke følger forvaltningslovens +krav ved mottak av meldinger sendt inn via FiksGataMi. La derfor +nettopp inn denne kommentaren til artikkelen:

+ +

+ +

Her er en liten faktaoppdatering om FiksGataMi-tjenesten, da noen +ser ut til å ha misforstått hvordan den fungerer.

+ +

FiksGataMi er et privat initiativ opprettet og drevet av +medlemsforeningen NUUG. FiksGataMi tar imot meldinger om feil i +offentlig infrastruktur, og sender meldingen skriftlig videre på vegne +av innmelder til aktuell aktør i det offentlige, det være seg kommune, +fylke eller vegvesenregion. Offentlig etat blir valgt ut fra +geografisk plassering og kategori valgt av innsender. Offentlige +etater er i følge forvaltningsloven pliktig å følge opp og besvare +skriftlige henvendelser, og hvis noen av mottakerne ikke gjør dette +kan en klage på lovbrudd i det offentlige. FiksGataMi fungerer dermed +som en slags epostklient for innbyggerne der kopi av innsendte +meldinger gjøres tilgjengelig og knyttes til kartplassering for enkel +gjenfinning. Å sende inn nye problemrapporter via FiksGataMi er +dermed ikke avhengig av at kommunen aktivt må følge med på meldinger +hos FiksGataMi, da de får dem tilsendt på sine offisielle +epostmottakspunkter. Hvorvidt noe blir fikset og om innbyggerne er +opp til mottaker av meldingene. For Trondheim kommune er +mottaksadressen bydrift.vegdrift@trondheim.kommune.no, en adresse jeg +inntil jeg leste denne artikkelen trodde ble håndtert i henhold til +forvaltningslovens krav.

+ +

Kan ellers fortelle at 57 kommuner lenker til FiksGataMi fra sine +nettsider, og at 37 % (4182 av 11266 ) av problemrapportene sendt inn +via FiksGataMi er markert som løst i løsningen. Trondheim kommune har +fått tilbud om å få rapportene levert på datamaskinlesbart format i +stedet for epost, men har ikke takket ja så langt.

+ +

Vennlig hilsen Petter Reinholdtsen, en av NUUG-folkene bak FiksGataMi.no

+ +

+ +

Det høres for meg ut som om innbyggerne i Trondheim burde klage på +kommunens potensielle lovbrudd.

Germany is a core area for the +

Debian Edu interview: Mike Gabriel
+
2nd June 2012
+

Back in 2010, Mike Gabriel showed up on the Debian Edu and Skolelinux -user community, and this time I managed to get hold of Wolfgang -Schweer, a valuable contributor to the project from Germany. +mailing list. He quickly proved to be a valuable developer, and +thanks to his tireless effort we now have Kerberos integrated into the +Debian Edu +Squeeze version.

Who are you, and how do you spend your days?

-

I've studied Mathematics at the university 'Ruhr-Universität' in -Bochum, Germany. Since 1981 I'm working as a teacher at the school -"Westfalen-Kolleg -Dortmund", a second chance school. Here, young adults is given -the opportunity to get further education in order to do the school -examination 'Abitur', which will allow to study at a university. This -second chance is of value for those who want a better job perspective -or failed to get a higher school examination being teens.

- -

Besides teaching I was involved in developing online courses for a -blended learning project called 'abitur-online.nrw' and in some other -information technology related projects. For about ten years I've been -teacher and coordinator for the 'abitur-online' project at my -school. Being now in my early sixties, I've decided to leave school at -the end of April this year.

+

My name is Mike Gabriel, I am 38 years old and live near Kiel, +Schleswig-Holstein, Germany. I live together with a wonderful partner +(Angela Fuß) and two own children and two bonus children (contributed +by Angela).

+ +

During the day I am part-time employed as a system administrator +and part-time working as an IT consultant. The consultancy work +touches free software topics wherever and whenever possible. During +the nights I am a free software developer. In the gaps I also train in +becoming an osteopath.

+ +

Starting in 2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel) +have set up a free software project in the area of Kiel that aims at +introducing free software into schools. The project's name is +"IT-Zukunft Schule" (IT future for schools). The project links IT +skills with communication skills.

How did you get in contact with the Skolelinux/Debian Edu project?

-

The first information about Skolelinux must have come to my -attention years ago and somehow related to LTSP (Linux Terminal Server -Project). At school, we had set up a network at the beginning of 1997 -using Suse Linux on the desktop, replacing a Novell network. Since -2002, we used old machines from the city council of Dortmund as thin -clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of -reach. At home I'm using Debian since years and - subscribed to the -Debian news letter - heard from time to time about Skolelinux. About -two years ago I proposed to replace the (somehow undocumented and only -known to me) system at school by a well known Debian based system: -Skolelinux.

- -

Students and teachers appreciated the new system because of a -better look and feel and an enhanced access to local media on thin -clients. The possibility to alter and/or reset passwords using a GUI -was welcomed, too. Being able to do administrative tasks using a GUI -and to easily set up workstations using PXE was of very high value for -the admin teachers.

+

While preparing our own customised Linux distribution for +"IT-Zukunft Schule" we were repeatedly asked if we really wanted to +reinvent the wheel. What schools really need is already available, +people said. From this impulse we started evaluating other Linux +distributions that target being used for school networks.

+ +

At the end we short-listed two approaches and compared them: a +commercial Linux distribution developed by a company in Bremen, +Germany, and Skolelinux / Debian Edu. Between 12/2010 and 03/2011 we +went to several events and met people being responsible for marketing +and development of either of the distributions. Skolelinux / Debian +Edu was by far much more convincing compared to the other product that +got short-listed beforehand--across the full spectrum. What was most +attractive for me personally: the perspective of collaboration within +the developmental branch of the Debian Edu project itself.

+ +

In parallel with this, we talked to many local and not-so-local +people. People teaching at schools, headmasters, politicians, data +protection experts, other IT professionals.

+ +

We came to two conclusions:

+ +

First, a technical conclusion: What schools need is available in +bits and pieces here and there, and none of the solutions really fit +by 100%. Any school we have seen has a very individual IT setup +whereas most of each school's requirements could mapped by a standard +IT solution. The requirement to this IT solution is flexibility and +customisability, so that individual adaptations here and there are +possible. In terms of re-distributing and rolling out such a +standardised IT system for schools (a system that is still to some +degree customisable) there is still a lot of work to do here +locally. Debian Edu / Skolelinux has been our choice as the starting +point.

+ +

Second, a holistic conclusion: What schools need does not exist at +all (or we missed it so far). There are several technical solutions +for handling IT at schools that tend to make a good impression. What +has been missing completely here in Germany, though, is the enrolment +of people into using IT and teaching with IT. "IT-Zukunft Schule" +tries to provide an approach for this.

+ +

Only some schools have some sort of a media concept which explains, +defines and gives guidance on how to use IT in class. Most schools in +Northern Germany do not have an IT service provider, the school's IT +equipment is managed by one or (if the school is lucky) two (admin) +teachers, most of the workload these admin teachers get done in there +spare time.

+ +

We were surprised that only a very few admin teachers were +networked with colleagues from other schools. Basically, every school +here around has its individual approach of providing IT equipment to +teachers and students and the exchange of ideas has been quasi +non-existent until 2010/2011.

+ +

Quite some (non-admin) teachers try to avoid using IT technology in +class as a learning medium completely. Several reasons for this +avoidance do exist.

+ +

We discovered that no-one has ever taken a closer look at this +social part of IT management in schools, so far. On our quest journey +for a technical IT solution for schools, we discussed this issue with +several teachers, headmasters, politicians, other IT professionals and +they all confirmed: a holistic approach of considering IT management +at schools, an approach that includes the people in place, will be new +and probably a gain for all.

What do you see as the advantages of Skolelinux/Debian Edu?

-

It's open source, easy to set up, stable and flexible due to it's -Debian base. It integrates LTSP out-of-the-box. And it is documented! -So it was a perfect choice.

- -

Being open source, there are no license problems and so it's -possible to point teachers and students to programs like -OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It's of -high value to be able to adapt parts of the system to special needs of -a school and to choose where to get support for this.

+

There is a list of advantages: international context, openness to +any kind of contributions, do-ocracy policy, the closeness to Debian, +the different installation scenarios possible (from stand-alone +workstation to complex multi-server sites), the transparency within +project communication, honest communication within the group of +developers, etc.

What do you see as the disadvantages of Skolelinux/Debian Edu?

-

Nothing yet.

+

Every coin has two sides:

+ +

Technically: BTS issue +#311188, tricky upgradability of a Debian Edu main server, network +client installations on top of a plain vanilla Debian installation +should become possible sometime in the near future, one could think +about splitting the very complex package debian-edu-config into +several portions (to make it easier for new developers to +contribute).

+ +

Another issue I see is that we (as Debian Edu developers) should +find out more about the network of people who do the marketing for +Debian Edu / Skolelinux. There is a very active group in Germany +promoting Skolelinux on the bigger Linux Days within Germany. Are +there other groups like that in other countries? How can we bring +these marketing people together (marketing group A with group B and +all of them with the group of Debian Edu developers)? During the last +meeting of the German Skolelinux group, I got the impression of people +there being rather disconnected from the development department of +Debian Edu / Skolelinux.

Which free software do you use daily?

-

At home (Debian Sid with Gnome Desktop): Iceweasel, LibreOffice, -Mutt, Gedit, Document Viewer, Midnight Commander, flpsed (PDF -Annotator). At school (Skolelinux Lenny): Iceweasel, Gedit, -LibreOffice.

+

For my daily business, I do not use commercial software at all.

+ +

For normal stuff I use Iceweasel/Firefox, Libreoffice.org. For +serious text writing I prefer LaTeX. I use gimp, inkscape, scribus for +more artistic tasks. I run virtual machines in KVM and Virtualbox.

+ +

I am one of the upstream developers of X2Go. In 2010 I started the +development of a Python based X2Go Client, called PyHoca-GUI. +PyHoca-GUI has brought forth a Python X2Go Client API that currently +is being integrated in Ubuntu's software center.

+ +

For communications I have my own Kolab server running using Horde +as web-based groupware client. For IRC I love to use irssi, for Jabber +I have several clients that I use, mostly pidgin, though. I am also +the Debian maintainer of Coccinella, a Jabber-based interactive +whiteboard.

+ +

My favourite terminal emulator is KDE's Yakuake.

Which strategy do you believe is the right one to use to get schools to use free software?

SOAP based webservice from Dell to check server support status
+
1st June 2012
+

A few years ago I wrote +how +to extract support status for your Dell and HP servers. Recently +I have learned from colleges here at the +University of Oslo that Dell have +made this even easier, by providing a SOAP based web service. Given +the service tag, one can now query the Dell servers and get machine +readable information about the support status. This perl code +demonstrate how to do it:

+ +

+use strict;
+use warnings;
+use SOAP::Lite;
+use Data::Dumper;
+my $GUID = '11111111-1111-1111-1111-111111111111';
+my $App = 'test';
+my $servicetag = $ARGV[0] or die "Please supply a servicetag. $!\n";
+my ($deal, $latest, @dates);
+my $s = SOAP::Lite
+    -> uri('http://support.dell.com/WebServices/')
+    -> on_action( sub { join '', @_ } )
+    -> proxy('http://xserv.dell.com/services/assetservice.asmx')
+    ;
+my $a = $s->GetAssetInformation(
+    SOAP::Data->name('guid')->value($GUID)->type(''),
+    SOAP::Data->name('applicationName')->value($App)->type(''),
+    SOAP::Data->name('serviceTags')->value($servicetag)->type(''),
+);
+print Dumper($a -> result) ;
+

+ +

The output can look like this:

+ +

+$VAR1 = {
+          'Asset' => {
+                     'Entitlements' => {

I have not been able to find any documentation from Dell about this +service outside the +inline +documentation, and according to +one +comment it can have stability issues, but it is a lot better than +scraping HTML pages. :)

Wonder if HP and other server vendors have a similar service. If +you know of one, drop me an email. :)

Linux-skoler har høyere PC-tetthet enn landsgjennomsnittet - pressemelding fra FRiSK
-
30th March 2012
-

I dag har FRiSK -sendt ut følgende pressemelding basert på mine beregninger av -PC-tetthet på Linux-skoler:

- -

Linux-skoler har høyere PC-tetthet enn -landsgjennomsnittet

- -

Oslo, 30 Mars 2012

- -

Det er store forskjeller på skolenes digitale tilstand, viser -undersøkelsen Monitor 2011 som er laget på oppdrag fra -Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i -skolen, og om de med Linux i skolen gjør det bedre bedre eller -dårligere enn snittet i landet.

- -

Nå har vi tallene. Skoler med Linux har 36% større PC-tetthet en -landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større -PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i -Nord-Odal:

- -

"Vi erfarer at klienter med Skolelinux har god funksjon -til de er 8 til 10 år gamle. Dette er omtrent dobbelt så lenge som -andre løsninger, og skolene får mer datautstyr for -pengene."

- -

Undersøkelsen baserer seg på 56 skoler som har gjort det offentlig -at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er -med Windows i skolenettet. Når en sammenligner PC-tetthetene på -skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal, -Nord-Odal og Randaberg, er det i snitt 2,28 elev pr. PC på skolene med -Linux. På landsbasis er det 3.11 elev per PC i grunnskolen, i følge -side 95 i Monitor-rapporten for 2011. Målingen viser dermed 36% større -PC-tetthet i skoler med Linux.

Om Skolelinux/Debian Edu

- -

Skolelinux har til hensikt å gi alle barn full tilgang til -skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med -godt over 100 skoleaktuelle programmene laget for læring. De fleste -programmene er oversatt til over 50 språk. Elevene skal også kunne -studere alle sider av dataprogrammene. Derfor følger også kildekode -med. Elever med interesse kan lære av eksperter som har laget -systemet. Dette med enkelt programmering i læreprogram som KTurtle, -til profesjonelle verktøy som Qt Creator eller Java.

- -

Skolelinux er laget for sentralisert drift, der alt teknisk -administrasjon av alle skolene kan gjøres sentralt fra kommunehuset -eller sentralt i en region. F.eks. drifter to-tre personer 70.000 -skoledatamaskiner på 200 skoler i delstaten Extremadura i -Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten -over til Debian på 40.000 datamaskiner i administrasjonen. Det er idag -mange selskap som tilbyr profesjonell støtte til innføring og drift i -Norge og verden.

Veileder fra DIFI om publisering av offentlige data
+
1st June 2012
+

På onsdag rakk jeg såvidt innom +Oslo Open Data Forums +møte, og fikk lagt hendene mine på DIFIs helt nye veileder +"Åpne data. Del og skap +verdier. Veileder i tilgjengeliggjøring av offentlig data" (også +tilgjengelig +som PDF fra DIFI).

+ +

Veilederen er veldig bra, og nevner viktige problemstillinger og +skisserer f.eks. både verdiskapningspotensialet og formatmulighetene +som en bør ha i bakhodet når en publiserer offentlig informasjon på +maskinlesbart format. Kildekoden til veilederen er +tilgjengelig via +github, og en kan rapportere tilbakemeldinger og forslag til +forbedringer der (eller via epost og twitter for de som ønsker +det).

+ +

Det eneste jeg virkelig savnet i veilederen var omtale av +w3cs +stjerneklassifisering av åpne datakilder, som jeg tror ville være +nyttige mentale knagger for de som vurderer å publisere sin +informasjon på som åpne data. Jeg har +rapportert +en github-bug om dette, så får vi se hvordan den blir behandlet.

+ +

Det slo meg at det var veldig lite konkret i veilederen om valg av +bruksvilkår ved publisering (aka lisens), men jeg er ikke sikker på om +det hører hjemme der, da det er et vanskelig tema som kanskje heller +hører hjemme i sin egen veileder. Uansett, anbefaler alle å ta en +titt på veilederen og sikre at alle offentlige etater en har kontakt +med får en kopi.
