                <pubDate>Tue, 19 Jun 2012 10:00:00 +0200</pubDate>
                <description>&lt;p&gt;Aftenposten melder i dag at selgerne av
&lt;a href=&quot;www.erlikoslo.no/&quot;&gt;gatemagasinet =Oslo&lt;/a&gt;
&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/Oslo-selgerne-irritert-pa-nytt-gatemagasin-6850970.html&quot;&gt;er
irritert&lt;/a&gt; på at det er kommet en konkurrent på banen fra
organisasjonen &lt;a href=&quot;http://oslo.folkerfolk.no/&quot;&gt;Folk er Folk&lt;/a&gt;,
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 &quot;rumenerne&quot; og andre utenlandske tiggere å selge
gatemagasinet sitt.  Det ble rapportert for noen år siden at
&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/Ikke-rom-i-herberget-6677803.html&quot;&gt;utenlandske
tiggere ikke var velkomne som selgere&lt;/a&gt;, og å opprette en konkurrent
virker da for meg som et rasjonelt alternativ.  Og at &quot;rumerene&quot;
utelukkes gjelder visst ikke bare i Oslo.  I Adresseavisen fant jeg en
artikkel om at selgerne av gateavisen Sorgenfri i Trondheim også
&lt;a href=&quot;http://www.adressa.no/nyheter/trondheim/article1122005.ece?index=20&quot;&gt;utelukker
utenlandske selgere&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;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
&lt;a href=&quot;http://www.dagbladet.no/kultur/2008/07/29/542041.html&quot;&gt;leserbrev
fra en av stifterne av =Oslo&lt;/a&gt;, som protesterte på
&lt;a href=&quot;http://www.dagbladet.no/nyheter/2008/07/23/541530.html&quot;&gt;påstander
fra likestillingsombudet om diskriminering&lt;/a&gt; og forteller at =Oslo
krever at de som selger magasinet skal kunne kommunisere med kundene
for å kunne representere magasinet utad, og at &quot;rumererne&quot; 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.&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

                <title>SQL-database med anbud publisert på Doffin</title>
                <link>http://people.skolelinux.org/pere/blog/SQL_database_med_anbud_publisert_p__Doffin.html</link>
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/SQL_database_med_anbud_publisert_p__Doffin.html</guid>
                <pubDate>Fri, 15 Jun 2012 13:30:00 +0200</pubDate>
                <description>&lt;p&gt;&lt;a href=&quot;http://www.doffin.no/&quot;&gt;Doffin&lt;/a&gt; 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 &lt;a href=&quot;htt://www.nuug.no/&quot;&gt;NUUG-prosjekt&lt;/a&gt;
laget en &lt;a href=&quot;http://scraperwiki.com/&quot;&gt;Scraperwiki&lt;/a&gt;-skraper som
lager en
&lt;a href=&quot;https://scraperwiki.com/scrapers/norwegian-doffin/&quot;&gt;SQL-database
med nøkkelinformasjonen fra Doffin&lt;/a&gt;, 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.&lt;/p&gt;

&lt;p&gt;Jeg var litt usikker på om det var rettighetsproblemer knyttet til
skraping av informasjon fra Doffin, men ser i
&lt;a href=&quot;http://www.doffin.no/sitehelp/help_terms.aspx&quot;&gt;vilkårene til
Doffin&lt;/a&gt; følgende:&lt;/p&gt;

&lt;p&gt;&lt;blockquote&gt;

&lt;p&gt;Opphavsrett mv&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

                <title>Debian Edu - some ideas for the future versions</title>
                <link>http://people.skolelinux.org/pere/blog/Debian_Edu___some_ideas_for_the_future_versions.html</link>
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu___some_ideas_for_the_future_versions.html</guid>
                <pubDate>Mon, 11 Jun 2012 14:30:00 +0200</pubDate>
                <description>&lt;p&gt;During my work on
&lt;a href=&quot;http://www.debian.org/News/2012/20120311.nb.html&quot;&gt;Debian Edu
based on Squeeze&lt;/a&gt;, 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.&lt;/p&gt;

&lt;p&gt;&lt;ul&gt;

&lt;li&gt;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.&lt;/li&gt;

&lt;li&gt;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:
&lt;ul&gt;

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

&lt;/ul&gt;&lt;/li&gt;

&lt;li&gt;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&lt;/li&gt;

&lt;li&gt;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.&lt;/li&gt;

&lt;li&gt;Fix partman-auto to allow us to abort the installation before
touching the disk if the disk is too small.  This is
&lt;a href=&quot;http://bugs.debian.org/653305&quot;&gt;BTS report #653305&lt;/a&gt; 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.&lt;/li&gt;

&lt;li&gt;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.

&lt;li&gt;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.&lt;/li&gt;

&lt;li&gt;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.&lt;/li&gt;

&lt;li&gt;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..&lt;/li&gt;

&lt;li&gt;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.&lt;/li&gt;

&lt;li&gt;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.&lt;/li&gt;

&lt;li&gt;We should configure Kerberos to update LDAP and Samba password
when changing password using the Kerberos protocol.  The hook was
requested in &lt;a href=&quot;http://bugs.debian.org/588968&quot;&gt;BTS report
#588968&lt;/a&gt; and is now available in Wheezy.  We might need to write a
MIT Kerberos plugin in C to get this.&lt;/li&gt;

&lt;li&gt;We should clean up the set of applications installed by default.
&lt;ul&gt;

&lt;li&gt;reduce the number of chemistry visualisers&lt;/li&gt;
&lt;li&gt;consider dropping xpaint&lt;/li&gt;
&lt;li&gt;and probably more?&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;

&lt;li&gt;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).&lt;/li&gt;


&lt;li&gt;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.&lt;/li&gt;

&lt;li&gt;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.&lt;/li&gt;

&lt;li&gt;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 &quot;it is documented&quot; method of today.&lt;/li&gt;

&lt;li&gt;A feature used in several schools is the ability for a teacher to
&quot;take over&quot; the desktop of individual or all computers in the room.
There are at least three implementations,
&lt;a href=&quot;italc.sourceforge.net/&quot;&gt;italc&lt;/a&gt;,
&lt;a href=&quot;http://www.itais.net/help/en/&quot;&gt;controlaula&lt;/a&gt; og
&lt;a href=&quot;http://www.epoptes.org/&quot;&gt;epoptes&lt;/a&gt; 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.&lt;/li&gt;

&lt;li&gt;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.&lt;/li&gt;

&lt;/ul&gt;&lt;/p&gt;

&lt;p&gt;I guess we will discover more as we continue to work on the Wheezy
version.&lt;/p&gt;

                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Litt_statistikk_fra_Offentlig_Elektronisk_postjournal.html</guid>
                <pubDate>Sun, 10 Jun 2012 20:30:00 +0200</pubDate>
                <description>&lt;p&gt;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
&lt;a href=&quot;http://www.oep.no/&quot;&gt;Offentlig Elektronisk Postjournal
(OEP)&lt;/a&gt;, FAD/DIFIs fellesløsning for departementer og statlige
etater.&lt;/p&gt;

&lt;p&gt;Her er antall oppføringer pr. måned det siste året,
&lt;a href=&quot;https://api.scraperwiki.com/api/1.0/datastore/sqlite?format=htmltable&amp;name=postliste-oep&amp;query=select%20strftime(%22%25Y-%25m%22%2C%20%60recordpublishdate%60)%20as%20oeppubmonth%2C%20count(*)%20from%20%60swdata%60%20group%20by%20oeppubmonth%20order%20by%20oeppubmonth&quot;&gt;summert
opp&lt;/a&gt; ved hjelp av
&lt;a href=&quot;https://scraperwiki.com/scrapers/postliste-oep/&quot;&gt;en
Scraperwiki-database&lt;/a&gt;.  Merk at denne Scraperwikien har
ytelsesproblemer pga. mengden data. &lt;/p&gt;

&lt;p&gt;&lt;table border=&quot;1&quot;&gt;
&lt;tr&gt;&lt;th&gt;Måned&lt;/th&gt;&lt;th&gt;Antall&lt;/th&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;2011-07&lt;/td&gt;&lt;td&gt;164355&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;2011-08&lt;/td&gt;&lt;td&gt;153662&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;2011-09&lt;/td&gt;&lt;td&gt;173134&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;2011-10&lt;/td&gt;&lt;td&gt;170665&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;2011-11&lt;/td&gt;&lt;td&gt;198409&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;2011-12&lt;/td&gt;&lt;td&gt;175908&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;2012-01&lt;/td&gt;&lt;td&gt;206875&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;2012-02&lt;/td&gt;&lt;td&gt;202862&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;2012-03&lt;/td&gt;&lt;td&gt;204225&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;2012-04&lt;/td&gt;&lt;td&gt;207931&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td&gt;2012-05&lt;/td&gt;&lt;td&gt;223754&lt;/td&gt;&lt;/tr&gt;
&lt;/table&gt;&lt;/p&gt;

&lt;p&gt;Det er også interessant å se hvor ofte ulike etater sender inn sine
journaloppføringer til OEP.  OEP inneholder en liste med sist
innrapporteringsdato for alle som sender til OEP, og ved å se når og
hvor ofte det blir sendt inn fra etatene kan
&lt;a href=&quot;https://api.scraperwiki.com/api/1.0/datastore/sqlite?format=htmltable&amp;name=postliste-oep-deliverydates&amp;query=select%20agency%2C%0A(julianday(datetime(&#39;now&#39;))%20-%20%0A%20julianday(min(%60deliverydate%60)))%2Fcount(*)%20as%20dayfreq%2C%0A%20count(*)%0Afrom%20%60swdata%60%20group%20by%20agency%20order%20by%20dayfreq%20desc&quot;&gt;frekvensen
beregnes&lt;/a&gt;.  Her er bunnlista, dvs. de som leverer sjeldnere enn hver 10.

&lt;tr&gt; &lt;td&gt;Medietilsynet&lt;/td&gt; &lt;td&gt;33.7527546296&lt;/td&gt; &lt;td&gt;1&lt;/td&gt; &lt;/tr&gt;
&lt;tr&gt; &lt;td&gt;Departementenes servicesenter&lt;/td&gt; &lt;td&gt;23.8763773148&lt;/td&gt; &lt;td&gt;2&lt;/td&gt; &lt;/tr&gt;
&lt;tr&gt; &lt;td&gt;Kunnskapsdepartementet&lt;/td&gt; &lt;td&gt;15.8763773148&lt;/td&gt; &lt;td&gt;2&lt;/td&gt; &lt;/tr&gt;

&lt;tr&gt; &lt;td&gt;Toll- og avgiftsdirektoratet&lt;/td&gt; &lt;td&gt;15.3763773148&lt;/td&gt; &lt;td&gt;2&lt;/td&gt; &lt;/tr&gt;
&lt;tr&gt; &lt;td&gt;Fredskorpset&lt;/td&gt; &lt;td&gt;12.5842515432&lt;/td&gt; &lt;td&gt;3&lt;/td&gt; &lt;/tr&gt;
&lt;tr&gt; &lt;td&gt;Statens legemiddelverk&lt;/td&gt; &lt;td&gt;12.1881886574&lt;/td&gt; &lt;td&gt;4&lt;/td&gt; &lt;/tr&gt;
&lt;tr&gt; &lt;td&gt;Utlendingsnemnda&lt;/td&gt; &lt;td&gt;11.5842515432&lt;/td&gt; &lt;td&gt;3&lt;/td&gt; &lt;/tr&gt;
&lt;tr&gt; &lt;td&gt;Politidirektoratet&lt;/td&gt; &lt;td&gt;10.9175848765&lt;/td&gt; &lt;td&gt;3&lt;/td&gt; &lt;/tr&gt;
&lt;tr&gt; &lt;td&gt;Skattedirektoratet&lt;/td&gt; &lt;td&gt;10.9175848765&lt;/td&gt; &lt;td&gt;3&lt;/td&gt; &lt;/tr&gt;
&lt;tr&gt; &lt;td&gt;Statens innkrevingssentral&lt;/td&gt; &lt;td&gt;10.5842515432&lt;/td&gt; &lt;td&gt;3&lt;/td&gt; &lt;/tr&gt;
&lt;tr&gt; &lt;td&gt;Barne-, ungdoms- og familiedirektoratet&lt;/td&gt; &lt;td&gt;10.2509182099&lt;/td&gt; &lt;td&gt;3&lt;/td&gt; &lt;/tr&gt;
&lt;tr&gt; &lt;td&gt;Kunst i offentlige rom&lt;/td&gt; &lt;td&gt;10.2509182099&lt;/td&gt; &lt;td&gt;3&lt;/td&gt; &lt;/tr&gt;

&lt;/table&gt;&lt;/p&gt;

&lt;p&gt;En kan beregne lignende frekvenser ved å sammenligne
journalføringsdato med publiseringsdato for hver enkelt oppføring i
OEP, men den lenken legger jeg ikke ved her for å unngå at
søkemotorroboter begynner å overbelaste Scraperwiki-databasen.&lt;/p&gt;

&lt;p&gt;Jeg har spurt Norges geologiske undersøkelse om hvorfor de leverer
så sjelden, og det kommer av at de har problemer etter oppgradering av
arkivsystemet sitt og jobber med å fikse det slik at de kan gå tilbake
til å levere hver uke.  Har ikke undersøkt noen av de andre.&lt;/p&gt;

                <description>&lt;p&gt;Slashdot got a story about Intel planning a
&lt;a href=&quot;http://entertainment.slashdot.org/story/12/06/09/0012247/intel-to-launch-tv-service-with-facial-recognition-by-end-of-the-year&quot;&gt;TV
with face recognition&lt;/a&gt; to recognise the viewer, and it occurred to
me that it would be more interesting to turn it around, and do face
recognition on the TV image itself.  It could let the viewer know who
is present on the screen, and perhaps look up their credibility,
company affiliation, previous appearances etc for the viewer to better
evaluate what is being said and done.  That would be a feature I would
be willing to pay for.&lt;/p&gt;

&lt;p&gt;I would not be willing to pay for a TV that point a camera on my
household, like the big brother feature apparently proposed by Intel.
It is the telescreen idea fetched straight out of the book
&lt;a href=&quot;http://gutenberg.net.au/ebooks01/0100021.txt&quot;&gt;1984 by George
Orwell&lt;/a&gt;.&lt;/p&gt;

                <description>&lt;p&gt;A few days ago
&lt;a href=&quot;http://people.skolelinux.org/pere/blog/SOAP_based_webservice_from_Dell_to_check_server_support_status.html&quot;&gt;I
reported how to get&lt;/a&gt; the support status out of Dell using an
unofficial and undocumented SOAP API, which I since have found out was
&lt;a href=&quot;http://lists.us.dell.com/pipermail/linux-poweredge/2012-February/045959.html&quot;&gt;discovered
by Daniel De Marco in february&lt;/a&gt;.  Combined with my web scraping
code for HP, Dell and IBM
&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Checking_server_hardware_support_status_for_Dell__HP_and_IBM_servers.html&quot;&gt;from
2009&lt;/a&gt;, I got inspired and wrote
&lt;a href=&quot;https://views.scraperwiki.com/run/computer-hardware-support-status/&quot;&gt;a
web service&lt;/a&gt; based on Scraperwiki to make it easy to look up the
support status and get a machine readable result back.&lt;/p&gt;

&lt;p&gt;This is what it look like at the moment when asking for the JSON
output:

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

&lt;p&gt;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.&lt;/p&gt;

                <pubDate>Sat, 2 Jun 2012 19:30:00 +0200</pubDate>
                <description>&lt;p&gt;Jeg oppdaget nylig en
&lt;a href=&quot;http://www.adressa.no/nyheter/trondheim/article1831198.ece&quot;&gt;artikkel
i Adresseavisa&lt;/a&gt; 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:&lt;p&gt;

&lt;p&gt;&lt;blockquote&gt;

&lt;p&gt;Her er en liten faktaoppdatering om FiksGataMi-tjenesten, da noen
ser ut til å ha misforstått hvordan den fungerer.&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;Vennlig hilsen Petter Reinholdtsen, en av NUUG-folkene bak FiksGataMi.no&lt;/p&gt;

&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;Det høres for meg ut som om innbyggerne i Trondheim burde klage på
kommunens potensielle lovbrudd.&lt;/p&gt;

                <title>Debian Edu interview: Mike Gabriel</title>
                <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Mike_Gabriel.html</link>
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Mike_Gabriel.html</guid>
                <pubDate>Sat, 2 Jun 2012 15:00:00 +0200</pubDate>
                <description>&lt;p&gt;Back in 2010, Mike Gabriel showed up on the
&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu and Skolelinux&lt;/a&gt;
mailing list.  He quickly proved to be a valuable developer, and
thanks to his tireless effort we now have Kerberos integrated into the
&lt;a href=&quot;http://www.debian.org/News/2012/20120311.html&quot;&gt;Debian Edu
Squeeze&lt;/a&gt; version.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;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).&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;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&#39;s name is
&quot;IT-Zukunft Schule&quot; (IT future for schools). The project links IT
skills with communication skills.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux/Debian Edu
project?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;While preparing our own customised Linux distribution for
&quot;IT-Zukunft Schule&quot; 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.&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;We came to two conclusions:&lt;/p&gt;

&lt;p&gt;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&#39;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.&lt;/p&gt;

&lt;p&gt;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. &quot;IT-Zukunft Schule&quot;
tries to provide an approach for this.&lt;/p&gt;

&lt;p&gt;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&#39;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.&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
Edu?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux/Debian
Edu?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Every coin has two sides:&lt;/p&gt;

&lt;p&gt;Technically: &lt;a href=&quot;http://bugs.debian.org/311188&quot;&gt;BTS issue
#311188&lt;/a&gt;, 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).&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;For my daily business, I do not use commercial software at all.&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;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&#39;s software center.&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;My favourite terminal emulator is KDE&#39;s Yakuake.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
get schools to use free software?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Communicate, communicate, communicate. Enrol people, enrol people,
enrol people.&lt;/p&gt;

                <pubDate>Fri, 1 Jun 2012 15:20:00 +0200</pubDate>
                <description>&lt;p&gt;A few years ago I wrote
&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Checking_server_hardware_support_status_for_Dell__HP_and_IBM_servers.html&quot;&gt;how
to extract support status&lt;/a&gt; for your Dell and HP servers.  Recently
I have learned from colleges here at the
&lt;a href=&quot;http://www.uio.no/&quot;&gt;University of Oslo&lt;/a&gt; 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:&lt;/p&gt;

&lt;p&gt;&lt;pre&gt;
use strict;
use warnings;
use SOAP::Lite;
use Data::Dumper;
my $GUID = &#39;11111111-1111-1111-1111-111111111111&#39;;
my $App = &#39;test&#39;;
my $servicetag = $ARGV[0] or die &quot;Please supply a servicetag. $!\n&quot;;
my ($deal, $latest, @dates);
my $s = SOAP::Lite
    -&gt; uri(&#39;http://support.dell.com/WebServices/&#39;)
    -&gt; on_action( sub { join &#39;&#39;, @_ } )
    -&gt; proxy(&#39;http://xserv.dell.com/services/assetservice.asmx&#39;)
    ;
my $a = $s-&gt;GetAssetInformation(
    SOAP::Data-&gt;name(&#39;guid&#39;)-&gt;value($GUID)-&gt;type(&#39;&#39;),
    SOAP::Data-&gt;name(&#39;applicationName&#39;)-&gt;value($App)-&gt;type(&#39;&#39;),
    SOAP::Data-&gt;name(&#39;serviceTags&#39;)-&gt;value($servicetag)-&gt;type(&#39;&#39;),
);
print Dumper($a -&gt; result) ;
&lt;/pre&gt;&lt;/p&gt;

&lt;p&gt;The output can look like this:&lt;/p&gt;

&lt;p&gt;&lt;pre&gt;
$VAR1 = {
          &#39;Asset&#39; =&gt; {
                     &#39;Entitlements&#39; =&gt; {
                                       &#39;EntitlementData&#39; =&gt; [
                                                            {
                                                              &#39;EntitlementType&#39; =&gt; &#39;Expired&#39;,

                                        }
                   }
        };
&lt;/pre&gt;&lt;/p&gt;

&lt;p&gt;I have not been able to find any documentation from Dell about this
service outside the
&lt;a href=&quot;http://xserv.dell.com/services/assetservice.asmx?op=GetAssetInformation&quot;&gt;inline
documentation&lt;/a&gt;, and according to
&lt;a href=&quot;http://iboyd.net/index.php/2012/02/14/updated-dell-warranty-information-script/&quot;&gt;one
comment&lt;/a&gt; it can have stability issues, but it is a lot better than
scraping HTML pages. :)&lt;/p&gt;

&lt;p&gt;Wonder if HP and other server vendors have a similar service.  If
you know of one, drop me an email. :)&lt;/p&gt;

                <pubDate>Fri, 1 Jun 2012 10:40:00 +0200</pubDate>
                <description>&lt;p&gt;På onsdag rakk jeg såvidt innom
&lt;a href=&quot;http://www.meetup.com/osloopendata/&quot;&gt;Oslo Open Data Forums&lt;/a&gt;
møte, og fikk lagt hendene mine på DIFIs helt nye veileder
&quot;&lt;a href=&quot;http://veileder.data.norge.no/&quot;&gt;Åpne data.  Del og skap
verdier.  Veileder i tilgjengeliggjøring av offentlig data&lt;/a&gt;&quot; (også
&lt;a href=&quot;http://www.difi.no/filearchive/veileder-i-tilgjengeliggjoring-av-offentlig-data-web.pdf&quot;&gt;tilgjengelig
som PDF&lt;/a&gt; fra DIFI).&lt;/p&gt;

&lt;p&gt;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
&lt;a href=&quot;https://github.com/difi/veileder-opnedata&quot;&gt;tilgjengelig via
github&lt;/a&gt;, og en kan rapportere tilbakemeldinger og forslag til
forbedringer der (eller via epost og twitter for de som ønsker
det).&lt;/p&gt;

&lt;p&gt;Det eneste jeg virkelig savnet i veilederen var omtale av
&lt;a href=&quot;http://www.w3.org/DesignIssues/LinkedData.html&quot;&gt;w3cs
stjerneklassifisering&lt;/a&gt; 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
&lt;a href=&quot;https://github.com/difi/veileder-opnedata/issues/1&quot;&gt;rapportert
en github-bug&lt;/a&gt; om dette, så får vi se hvordan den blir behandlet.&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;
