VÃ¥rt konkurransebidrag til #apps4norge bruker @opnedata
-
1st May 2013
-

For noen uker siden, innen fristen 2013-04-15, leverte jeg og -Morten Kjelkenes vårt bidrag til -DIFIs apps4norge-konkurranse -under lagnavnet NUUGs tannlegeteam. -Vi leverte følgende i idé-kategorien:

- -
- -

Tittel: Stikk innom tannlegen

- -

- -

Beskrivelse:

- -

Idéen - -

Gjøre det enklere å finne en tannlege som er praktisk for deg, der -pris og reisetid med kollektivt, til fots eller med bil er tatt med i -beregningen, ved å oppgi hvor en bor og jobber, og få forslag til -tannleger både i nærheten og på veien mellom disse stedene.

- -

Brukeren oppgir hjemmeadresse og jobbadresse, og kanskje også -barnehage. Så kan en også oppgi egen timelønn (for å beregne taps -arbeidsfortjeneste) og om en reiser med kollektivt, til fots eller -kjører bil. Så trykker en søk, og får opp en todelt side med kart og -tekstliste. I kartdelen vises aktuelle tannleger (for eksempel maks -7), og i tekstdelen er de samme tannlegene listet opp, med pris og -reisetid for kollektivtransport, og pris pluss reisekostnad hvis en -reiser med bil. En kan endre sorteringsrekkefølge for listen ved å -trykke på aktuell kolonne, og velge om en skal sortere på pris, -reisetid eller totalkostnad. Kun tannleger som tar imot nye kunder tas -i utganspunktet med i listen. Når brukeren trykker med musa en -tannlegemarkør på kartet kommer det en popup med detaljer om -tannlegen, den samme informasjonen som finnes i listen under kartet, -og lenke til mer informasjon om tannlegen.

- -

For hvert enkelt tannlegekontor er det tilgjengelig en -informasjonsside med adresse, hjemmesideurl, telefonnummer, lenke til -side for å finne reisebeskrivelse, åpningstider, etc.

How to fix a Thinkpad X230 with a broken 180 GB SSD disk
+
17th July 2013
+

Today I switched to +my +new laptop. I've previously written about the problems I had with +my new Thinkpad X230, which was delivered with an +180 +GB Intel SSD disk with Lenovo firmware that did not handle +sustained writes. My hardware supplier have been very forthcoming in +trying to find a solution, and after first trying with another +identical 180 GB disks they decided to send me a 256 GB Samsung SSD +disk instead to fix it once and for all. The Samsung disk survived +the installation of Debian with encrypted disks (filling the disk with +random data during installation killed the first two), and I thus +decided to trust it with my data. I have installed it as a Debian Edu +Wheezy roaming workstation hooked up with my Debian Edu Squeeze main +server at home using Kerberos and LDAP, and will use it as my work +station from now on.

+ +

As this is a solid state disk with no moving parts, I believe the +Debian Wheezy default installation need to be tuned a bit to increase +performance and increase life time of the disk. The Linux kernel and +user space applications do not yet adjust automatically to such +environment. To make it easier for my self, I created a draft Debian +package ssd-setup to handle this tuning. The +source +for the ssd-setup package is available from collab-maint, and it +is set up to adjust the setup of the machine by just installing the +package. If there is any non-SSD disk in the machine, the package +will refuse to install, as I did not try to write any logic to sort +file systems in SSD and non-SSD file systems.

+ +

I consider the package a draft, as I am a bit unsure how to best +set up Debian Wheezy with an SSD. It is adjusted to my use case, +where I set up the machine with one large encrypted partition (in +addition to /boot), put LVM on top of this and set up partitions on +top of this again. See the README file in the package source for the +references I used to pick the settings. At the moment these +parameters are tuned:

    -
  • sparer tid pÃ¥ tannlegebesøk
    • -
  • kan utnytte normal reisevei mellom hjem/jobb/barnehage
    • -
  • kan finne aktuell tannlege basert pÃ¥ flere kriterier
    • -
  • sile bort tannleger som ikke tar imot flere kunder
    • -
  • fÃ¥r kart som viser tannleger i nærheten, pÃ¥ tvers av kommunegrenser
    • -
- -

Grad av innovasjon, nytenkning og kreativitet

- -

Enkel tjeneste som fokuserer på det vi selv mener er relevant ved valg -av tannlege.

- -

Tjenestekonseptet kan også brukes til andre næringer, f.eks. lege, -butikk, leiebiler, hvis en har aktuell datakilde å koble med.

- -

Skulle gjerne hatt med vurdering av tannlegene tilgjengelig, slik -at en kunne finne "flinke" tannleger basert på et eller annet -kriterium.

- -

Markedspotensiale - potensiale for å slå gjennom hos mange -brukere

- -
    -
  • Alle som ønsker eller vurderer Ã¥ skaffe seg ny tannlege, f.eks. nyinnflyttede og studenter
    • -
  • Familier med en travel hverdag
    • -
-

Felles er at den gjør tannlegen lettere tilgjengelig for de som vil spare tid eller penger.

- -

Samfunnsøkonomisk nytte - bidrar til å løse -samfunnsutfordringer

- -

Kutter tid brukt på tannlegebesøk, og penger frigjøres som kan brukes på andre områder. Oppfordrer til bedre bruk av kollektivtransport ved å gi tips om tannleger i nærheten av allerede brukt reisevei mellom hjemme og jobb når en reiser kollektivt.

- -

X-faktor - “Det lille ekstra...”

- -

Denne tjenesten gir det lille ekstra ved at den ikke slår opp -avstand til tannlege fra et enkelt punkt men avstand fra en reisevei, -slik at en får flere tannleger å velge imellom og kanskje kan spare -enda mer tid og penger enn en ville gjort ved å sjekke kun de nærmest -hjemme eller jobb.

- -

Tjenesten gir informasjonen både som kart og som tekstlig oversikt, for å sikre at blinde og svaksynte kan få tilgang til informasjonen selv om de ikke får brukt kartvisningen.

Vinneren annonseres 2013-05-08 ved -prisutdelingen -hos DIFI 09:00 til 12:00. Konkurransen blir hard. Det meldes at -38 apper og 50 ideer er registrert som kandidater. Jeg frykter at jeg -ikke rekker innom selv, på grunn av jobb og forpliktelser på -hjemmebanen.

+

During installation, I cancelled the part where the installer fill +the disk with random data, as this would kill the SSD performance for +little gain. My goal with the encrypted file system is to ensure +those stealing my laptop end up with a brick and not a working +computer. I have no hope in keeping the really resourceful people +from getting the data on the disk (see +XKCD #538 for an explanation why). +Thus I concluded that adding the discard option to crypttab is the +right thing to do.

+ +

I considered using the noop I/O scheduler, as several recommended +it for SSD, but others recommended deadline and a benchmark I found +indicated that deadline might be better for interactive use.

+ +

I also considered using the 'discard' file system option for ext3 +and ext4, but read that it would give a performance hit ever time a +file is removed, and thought it best to that that slowdown once a day +instead of during my work.

+ +

My package do not set up tmpfs on /var/run, /var/lock and /tmp, as +this is already done by Debian Edu.

+ +

I have not yet started on the user space tuning. I expect +iceweasel need some tuning, and perhaps other applications too, but +have not yet had time to investigate those parts.

+ +

The package should work on Ubuntu too, but I have not yet tested it +there.

+ +

As for the answer to the question in the title of this blog post, +as far as I know, the only solution I know about is to replace the +disk. It might be possible to flash it with Intel firmware instead of +the Lenovo firmware. But I have not tried and did not want to do so +without approval from Lenovo as I wanted to keep the warranty on the +disk until a solution was found and they wanted the broken disks +back.

Intel SSD 520 Series 180 GB with Lenovo firmware still lock up from sustained writes
+
10th July 2013
+

A few days ago, I wrote about +the +problems I experienced with my new X230 and its SSD disk, which +was dying during installation because it is unable to cope with +sustained write. My supplier is in contact with +Lenovo, and they wanted to send a +replacement disk to try to fix the problem. They decided to send an +identical model, so my hopes for a permanent fix was slim.

+ +

Anyway, today I got the replacement disk and tried to install +Debian Edu Wheezy with encrypted disk on it. The new disk have the +same firmware version as the original. This time my hope raised +slightly as the installation progressed, as the original disk used to +die after 4-7% of the disk was written to, while this time it kept +going past 10%, 20%, 40% and even past 50%. But around 60%, the disk +died again and I was back on square one. I still do not have a new +laptop with a disk I can trust. I can not live with a disk that might +lock up when I download a new +Debian Edu / Skolelinux ISO or +other large files. I look forward to hearing from my supplier with +the next proposal from Lenovo.

+ +

The original disk is marked Intel SSD 520 Series 180 GB, +11S0C38722Z1ZNME35X1TR, ISN: CVCV321407HB180EGN, SA: G57560302, FW: +LF1i, 29MAY2013, PBA: G39779-300, LBA 351,651,888, LI P/N: 0C38722, +Pb-free 2LI, LC P/N: 16-200366, WWN: 55CD2E40002756C4, Model: +SSDSC2BW180A3L 2.5" 6Gb/s SATA SSD 180G 5V 1A, ASM P/N 0C38732, FRU +P/N 45N8295, P0C38732.

+ +

The replacement disk is marked Intel SSD 520 Series 180 GB, +11S0C38722Z1ZNDE34N0L0, ISN: CVCV315306RK180EGN, SA: G57560-302, FW: +LF1i, 22APR2013, PBA: G39779-300, LBA 351,651,888, LI P/N: 0C38722, +Pb-free 2LI, LC P/N: 16-200366, WWN: 55CD2E40000AB69E, Model: +SSDSC2BW180A3L 2.5" 6Gb/s SATA SSD 180G 5V 1A, ASM P/N 0C38732, FRU +P/N 45N8295, P0C38732.

+ +

The only difference is in the first number (serial number?), ISN, +SA, date and WNPP values. Mentioning all the details here in case +someone is able to use the information to find a way to identify the +failing disk among working ones (if any such working disk actually +exist).

Bitcoin er ikke anonymt - føres Stortinget bak lyset av finansministeren?
-
22nd April 2013
-

Bitcoin er mye i mediene for -tiden. Jeg følger med via Mylder for å finne -artikler som omtaler -temaet, og takket være dette oppdaget jeg at stortingsrepresentant -Ketil Solvik-Olsen fra FrP nylig har spurt finansminister Sigbjørn -Johnsen om hans syn på Bitcoin, og -fått -svar for noen dager siden. Jeg bet meg spesielt merke til -følgende formulering fra finansministeren:

- -

-«Det er også utfordringer ved at handel med Bitcoins er uregulert og -at transaksjonene er anonyme.» -

- -

At Bitcoin er anonymt er en myte som spres av både journalister og -andre, så det er ikke veldig overraskende at også finansministeren har -gått på limpinnen. Det er dog litt rart, da jeg håper at -finansdepartementet ikke baserer seg på rykter og myter når de -besvarer Stortinget. Men du trenger ikke bare tro på meg som kilde -til påstanden om at Bitcoin ikke er anonymt. Sondre Rønjom har -via Sikkerhetsbloggen -hos Nasjonal Sikkerhetsmyndighet uttalt følgende:

- -

-«At [bitcoin] i utgangspunktet -ikke er anonymt, -kommer kanskje som en overraskelse på mange.» -

- -

Enhver bevegelse av Bitcoin er offentlig tilgjengelig for alle på -Internet, og en må legge svært mye innsats inn hvis en skal hindre at -nettverksanalyse av transaksjonsloggene kan brukes til å identifisere -brukerne. F.eks. kan en enkelt se hva jeg har mottatt til min -offentliggjorte mottaksadresse ved å besøke blockexplorer og slå opp -adressen -15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b. -Det virker dermed på meg ganske klart at å påstå at -Bitcoin-transaksjoner er anonyme strengt tatt er å føre Stortinget bak -lyset.

- -

Finansministeren er ikke den eneste som har latt seg forlede av -medieomtalen. I spørsmålet fra Hr. Solvik-Olsen skriver han at «For -noen dager siden kom den første bitcoin-minibanken på Kypros», hvilket -så vidt jeg har klart å finne ut ikke er riktig. Det er annonsert -planer om en slik minibank (fra -BitcoinATM), men jeg finner -intet tegn til at en slik minibank er utplassert noe sted.

- -

Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til -mine aktiviteter, så setter jeg pris på Bitcoin-donasjoner til min -adresse -15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b.

The Thinkpad is dead, long live the Thinkpad X230?
+
5th July 2013
+

Half a year ago, I reported that I had to find a +replacement +for my trusty old Thinkpad X41. Unfortunately I did not have much +time to spend on it, and it took a while to find a model I believe +will do the job, but two days ago the replacement finally arrived. I +ended up picking a +Thinkpad X230 +with SSD disk (NZDAJMN). I first test installed Debian Edu Wheezy as +a roaming workstation, and it seemed to work flawlessly. But my +second installation with encrypted disk was not as successful. More +on that below.

+ +

I had a hard time trying to track down a good laptop, as my most +important requirements (robust and with a good keyboard) are never +listed in the feature list. But I did get good help from the search +feature at Prisjakt, which +allowed me to limit the list of interesting laptops based on my other +requirements. A bit surprising that SSD disk are not disks according +to that search interface, so I had to drop specifying the number of +disks from my search parameters. I also asked around among friends to +get their impression on keyboards and robustness.

+ +

So the new laptop arrived, and it is quite a lot wider than the +X41. I am not quite convinced about the keyboard, as it is +significantly wider than my old keyboard, and I have to stretch my +hand a lot more to reach the edges. But the key response is fairly +good and the individual key shape is fairly easy to handle, so I hope +I will get used to it. My old X40 was starting to fail, and I really +needed a new laptop now. :)

+ +

Turning off the touch pad was simple. All it took was a quick +visit to the BIOS during boot it disable it.

+ +

But there is a fatal problem with the laptop. The 180 GB SSD disk +lock up during load. And this happen when installing Debian Wheezy +with encrypted disk, while the disk is being filled with random data. +I also tested to install Ubuntu Raring, and it happen there too if I +reenable the code to fill the disk with random data (it is disabled by +default in Ubuntu). And the bug with is already known. It was +reported to Debian as BTS +report #691427 2012-10-25 (journal commit I/O error on brand-new +Thinkpad T430s ext4 on lvm on SSD). It is also reported to the Linux +kernel developers as +Kernel bugzilla +report #51861 2012-12-20 (Intel SSD 520 stops working under load +(SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the +Lenovo forums, both for +T430 +2012-11-10 and for +X230 +03-20-2013. The problem do not only affect installation. The +reports state that the disk lock up during use if many writes are done +on the disk, so it is much no use to work around the installation +problem and end up with a computer that can lock up at any moment. +There is even a +small C program +available that will lock up the hard drive after running a few +minutes by writing to a file.

+ +

I've contacted my supplier and asked how to handle this, and after +contacting PCHELP Norway (request 01D1FDP) which handle support +requests for Lenovo, his first suggestion was to upgrade the disk +firmware. Unfortunately there is no newer firmware available from +Lenovo, as my disk already have the most recent one (version LF1i). I +hope to hear more from him today and hope the problem can be +fixed. :)

A netbooting +environment is prepared using PXE, so after initial installation of +the main server from CD, DVD 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 fourth test release based on Debian Wheezy. Basically +this is an updated and slightly improved version compared to the +Squeeze release.

    +

    Software updates

    +
      +
    • Dropped ispell dictionaries from our default installation.
      • +
    • Dropped menu-xdg from the KDE desktop option, to drop the Debian + submenu. It was not included with Gnome, LXDE or Xfce, so this + brings KDE in line with the others.
      • +
    • Dropped xdrawchem, xjig and xsok from our default installation as + they don't have a desktop menu entry and thus won't show up in the + menu now that menu-xdg was removed.
      • +
    • Removed the killer system to kill left behind processes on + multi-user machines, as it was no longer able to understand when a + X display was in use and killed the processes of the active users + too.
      • +
    • Dropped the golearn (from goplay) package as the debtags in wheezy + are too few to make the package useful.

Sandy Island - øya som er synlig hver tirsdag og fredag?
-
7th April 2013
-

For en stund tilbake gikk nyheten om -Sandy -Island, en øy som var dukket opp på noen kart, men som ikke var -synlig når en sjekket den på satellittbilder. Dagbladet meldte for -eksempel at -«denne -øya finnes på kart, men ikke i virkeligheten». Noe senere begynte -jeg å lese -historier -om Ruffen til mine barn. Dette er historier om sjøormen Ruffen -skapt av Tor Åge Bringsværd, som starter med følgende beskrivelse:

- -

-«Langt ute i havet ligger en mystisk øy. Den er bare synlig hver -tirsdag og fredag. Derfor står den ikke på noe kart. På denne øya -ligger et slott, og i slottet bor en gammel, fin sjøormfamilie.» -

- -

Det virker åpenbart at Hr. Bringsværd tok feil når han trodde den -ikke var på noe kart, og at noen tydeligvis har vært i nærheten en -tirsdag eller en fredag og fått den med på et kart, mens -satellittbildene er tatt på noen av de fem andre dagene i uka og -dermed ikke ser øya. :)

- -

I følge -en -senere artikkel i Dagbladet hevder Shaun Higgins, en forsker fra -New Zealand, at et hvalfangstskip fra 1876 er opprinnelsen til at -spøkelsesøya i det hele tatt havnet på kartet. Det fremgår ikke fra -historien hvilken ukedag de var innom.

Jeg har stor sans for Tor Åge Bringsværd. Og han viste nylig en -svært fin side av seg selv da han sa ja til EFNs forespørsel om å gi -ut novellen Kodémus med -Creative Commons-lisens.

Isenkram 0.2 finally in the Debian archive
-
3rd April 2013
-

Today the Isenkram -package finally made it into the archive, after lingering in NEW -for many months. I uploaded it to the Debian experimental suite -2013-01-27, and today it was accepted into the archive.

- -

Isenkram is a system for suggesting to users what packages to -install to work with a pluggable hardware device. The suggestion pop -up when the device is plugged in. For example if a Lego Mindstorm NXT -is inserted, it will suggest to install the program needed to program -the NXT controller. Give it a go, and report bugs and suggestions to -BTS. :)

Automatically locate and install required firmware packages on Debian (Isenkram 0.4)
+
25th June 2013
+

It annoys me when the computer fail to do automatically what it is +perfectly capable of, and I have to do it manually to get things +working. One such task is to find out what firmware packages are +needed to get the hardware on my computer working. Most often this +affect the wifi card, but some times it even affect the RAID +controller or the ethernet card. Today I pushed version 0.4 of the +Isenkram package +including a new script isenkram-autoinstall-firmware handling the +process of asking all the loaded kernel modules what firmware files +they want, find debian packages providing these files and install the +debian packages. Here is a test run on my laptop:

+ +

+# isenkram-autoinstall-firmware 
+info: kernel drivers requested extra firmware: ipw2200-bss.fw ipw2200-ibss.fw ipw2200-sniffer.fw
+info: fetching http://http.debian.net/debian/dists/squeeze/Contents-i386.gz
+info: locating packages with the requested firmware files
+info: Updating APT sources after adding non-free APT source
+info: trying to install firmware-ipw2x00
+firmware-ipw2x00
+firmware-ipw2x00
+Preconfiguring packages ...
+Selecting previously deselected package firmware-ipw2x00.
+(Reading database ... 259727 files and directories currently installed.)
+Unpacking firmware-ipw2x00 (from .../firmware-ipw2x00_0.28+squeeze1_all.deb) ...
+Setting up firmware-ipw2x00 (0.28+squeeze1) ...
+# 
+

+ +

When all the requested firmware is present, a simple message is +printed instead:

+ +

+# isenkram-autoinstall-firmware 
+info: did not find any firmware files requested by loaded kernel modules.  exiting
+# 
+

+ +

It could use some polish, but it is already working well and saving +me some time when setting up new machines. :)

+ +

So, how does it work? It look at the set of currently loaded +kernel modules, and look up each one of them using modinfo, to find +the firmware files listed in the module meta-information. Next, it +download the Contents file from a nearby APT mirror, and search for +the firmware files in this file to locate the package with the +requested firmware file. If the package is in the non-free section, a +non-free APT source is added and the package is installed using +apt-get install. The end result is a slightly better working +machine.

+ +

I hope someone find time to implement a more polished version of +this script as part of the hw-detect debian-installer module, to +finally fix BTS report +#655507. There really is no need to insert USB sticks with +firmware during a PXE install when the packages already are available +from the nearby Debian mirror.

EFN nyutgir novellen Kodémus av Tor Åge Bringsværd
-
27th March 2013
-

For noen dager siden nevnte jeg at vi jobbet med å typesette en -novelle med DocBook. I dag ble -utgivelsen annonsert med følgende pressemelding fra Elektronisk -Forpost Norge), som jeg gjengir i sin helhet:

- -

- -

EFN nyutgir Kodémus:

- -

Tor Åge Bringsværd-novelle om IT og overvåkning fra -informasjonsteknologiens spedbarndom får nytt liv

- -

Elektronisk Forpost Norge (EFN) er veldig glad for anledningen til -å nyutgi Tor Åge Bringsværds novelle Kodémus i digitalt format for nye -(og gamle) generasjoner. Novellen ble skrevet så tidlig som vinteren -1968, og første gang trykt i novellesamlingen Probok på Gyldendal -samme år.

- -

Informasjonsteknologi spiller en sentral rolle i Kodémus, og det er -spennende å sammenligne beskrivelsen av IT fra 1968 med dagens IT i -2013. Forskjellene er mange -- men det er jammen likhetene også. Ikke -minst det at idag går jo nesten alle rundt med lillebrødre på seg!

- -

"Riktignok er det ikke påbudt å ha mobil," sier Thomas Gramstad, -leder i EFN. "Men vi holder på å lage et samfunn der det blir så -upraktisk eller tungvint å ikke ha det, at man i praksis ikke slipper -unna. Og disse lillebrødrene sladrer hele tiden til staten (og til -mange andre) om hvor vi er, hva vi gjør, hva vi bryr oss om, hva vi -liker..."

- -

Det at Kodémus åpenbart er skrevet i en annen tid med en annen type -IT og likevel virker så relevant idag, er i seg selv et hardtslående -tankekors.

- -

Tross sitt IT-tema fantes ikke Kodémus i elektronisk form, og -frivillige i EFN har skannet inn, OCR-tolket og korrekturlest -novellen, og deretter kodet den i en rekke digitale formater.

- -

Forfatteren har gitt tillatelse til publisering av Kodémus under ny -lisens, og novellen utgis av EFN med en Creative Commons (CC) -fribrukslisens (nærmere bestemt lisensen CC-BY-NC-ND). For leserne -eller brukerne innebærer dette at de får en klar og standardisert -beskjed om hvilke rettigheter de har til å dele novellen videre med -andre. For forfatteren innebærer dette økt synlighet og -tilgjengelighet for verket, slik at det ikke blir glemt, da -søkemotorer og nettlesere inneholder egne søkevalg for CC-lisenser, og -mange brukere søker etter verk som de vet de kan dele og bruke på -lovlig vis.

- -

EFN oppfordrer andre forfattere om å gi ut sine gamle tekster med -en fribrukslisens, slik at tekstene ikke blir glemt og for å stimulere -lovlig deling på nettet. EFN kan være behjelpelig med digitalisering -og utlegging på nett, i den grad det finnes kapasitet blant EFNs -medlemmer til dette. Vi mener at nyutgivelser av tekster under frie -lisenser kan øke interessen rundt forfatterskapet, og vil gjerne bidra -til dette.

- -

EFN utgir og deler med dette en novelle fra den digitale -informasjonsteknologiens tidligste barndom. En novelle som fortsatt er -full av vitalitet og aktualitet, og som derfor kan bidra til, og gi -ettertanke i dagens debatter om IT, personvern, overvåkning og -individets frihet og integritet.

- -

Du finner novellen her: -
http://efn.no/kodemus/

- -

i flere forskjellige formater, for ulike plattformer. Per idag -finnes novellen i disse formatene: EPUB, MOBI, XML, HTML, PDF og -txt. Det kan bli flere formater senere, og evt. frivillige -bidragsytere til dette er velkommen.

Jeg håper flere forfattere ser verdien av å gjøre kulturen -tilgjengelig for flere, og slår følge med Hr.

The value of a good distro wide test suite...
+
22nd June 2013
+

In the Debian Edu / +Skolelinux project, we include a post-installation test suite, +which check that services are running, working, and return the +expected results. It runs automatically just after the first boot on +test installations (using test ISOs), but not on production +installations (using non-test ISOs). It test that the LDAP service is +operating, Kerberos is responding, DNS is replying, file systems are +online resizable, etc, etc. And it check that the PXE service is +configured, which is the topic of this post.

+ +

The last week I've fixed the DVD and USB stick ISOs for our Debian +Edu Wheezy release. These ISOs are supposed to be able to install a +complete system without any Internet connection, but for that to +happen all the needed packages need to be on them. Thanks to our test +suite, I discovered that we had forgotten to adjust our PXE setup to +cope with the new names and paths used by the netboot d-i packages. +When Internet connectivity was available, the installer fall back to +using wget to fetch d-i boot images, but when offline it require +working packages to get it working. And ad the packages changed name +from debian-installer-6.0-netboot-$arch to +debian-installer-7.0-netboot-$arch, we no longer pulled in the +packages during installation. Without our test suite, I suspect we +would never have discovered this before release. Now it is fixed +right after we got the ISOs operational.

+ +

Another by-product of the test suite is that we can ask system +administrators with problems getting Debian Edu to work, to run the +test suite using /usr/sbin/debian-edu-test-install and see if +any errors are detected. This usually pinpoint the subsystem causing +the problem.

+ +

If you want to help us help kids learn how to share and create, +please join us on +#debian-edu on +irc.debian.org and the +debian-edu@ mailing +list.

Change the font, save the world (and save some money in the process)
-
26th March 2013
-

Would you like to help the environment and save money at the same -time, without much sacrifice? A small step could be to change the -font you use when printing.

- -

Three years ago, -Ars -Technica reported how the University of Wisconsin-Green Bay -changed their default front from -Arial to -Century -Gothic to save money. The Century Gothic font uses 30% less toner -than Arial to print the same text. In other word, you could cut your -toner costs by 30% (or actually, increase your toner supply life time -by more than 30%), by simply changing the default font used in your -prints.

- -

But it is not quite obvious how much one will save by switching. -The University of Wisconsin-Green Bay said it used $100,000 per year -on ink and toner cartridges, according to -a report from -TwinCities.com, and expected to save between $5,000 and $10,000 -per year by asking staff and students to use a different font. Not -all PDFs and documents are created internally, and those from external -sources will most likely still use a different font. Also, the -Century Gothic font is slightly wider than Arial, and thus might use -more sheets of paper to print the same text, so the total saving -depend on the documents printed.

- -

But it is definitely something to consider, if you want to reduce -the amount of trash, decrease the amount of toner used in the world, -and save some money in the process.

- -

Update 2013-04-10: If you want to know how much ink/toner could be -saved when switching between fonts, Inkfarm got a -service to calculate the -difference between font pairs. They also -recommend -which fonts to use to save ink. Check it out. :) While updating -this blog post, I also came across a blog post from InkCloners, -listing -the fonts they recommend, with Centory Gothic at the top.

Debian Edu interview: Victor Nițu
+
17th June 2013
+

The Debian Edu and +Skolelinux distribution have users and contributors all around the +globe. And a while back, an enterprising young man showed up on +our IRC channel +#debian-edu and started asking questions about how Debian Edu +worked. We answered as good as we could, and even convinced him to +help us with translations. And today I managed to get an interview +with him, to learn more about him.

+ +

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

+ +

I'm a 25 year old free software enthusiast, living in Romania, +which is also my country of origin. Back in 2009, at a New Year's Eve +party, I had a very nice beer discussion with a +friend, when we realized we have no organised Debian community in our +country. A few days later, we put together the infrastructure for such +community and even gathered a nice Debian-ish crowd. Since then, I +began my quest as a free software hacker and activist and I am +constantly trying to cover as much ground as possible on that +field.

+ +

A few years ago I founded a small web development company, which +provided me the flexible schedule I needed so much for my +activities. For the last 13 months, I have been the Technical Director +of Fundația Ceata, which is a free +software activist organisation endorsed by the FSF and the FSFE, and +the only one we have in our country.

+ +

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

+ +

The idea of participating in the Debian Edu project was a surprise +even to me, since I never used it before I began getting involved in +it. This year I had a great opportunity to deliver a talk on +educational software, and I knew immediately where to look. It was a +love at first sight, since I was previously involved with some of the +technologies the project incorporates, and I rapidly found a lot of +ways to contribute.

+ +

My first contributions consisted in translating the installer and +configuration dialogs, then I found some bugs to squash (I still +haven't fixed them yet though), and I even got my eyes on some other +areas where I can prove myself helpful. Since the appetite for free +software in my country is pretty low, I'll be happy to be the first +one around here advocating for the project's adoption in educational +environments, and maybe even get my hands dirty in creating a flavour +for our own needs. I am not used to make very advanced plannings, so +from now on, time will tell what I'll be doing next, but I think I +have a pretty consistent starting point.

+ +

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

+ +

Not a long time ago, I was in the position of configuring and +maintaining a LDAP server on some Debian derivative, and I must say it +took me a while. A long time ago, I was maintaining a bigger +Samba-powered infrastructure, and I must say I spent quite a lot of +time on it. I have similar stories about many of the services included +with Skolelinux, and the main advantage I see about it is the +out-of-the box availability of them, making it quite competitive when +it comes to managing a school's network, for example.

+ +

Of course, there is more to say about Skolelinux than the +availability of the software included, its flexibility in various +scenarios is something I can't wait to experiment "into the wild" (I +only played with virtual machines so far). And I am sure there is a +lot more I haven't discovered yet about it, being so new within the +project.

+ +

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

+ +

As usual, when it comes to Debian Blends, I see as the biggest +disadvantage the lack of a numerous team dedicated to the +project. Every day I see the same names in the changelogs, and I have +a constantly fear of the bus factor in this story. I'd like to see +Debian Edu advertised more as an entry point into the Debian +ecosystem, especially amongst newcomers and students. IMHO there are a +lot low-hanging fruits in terms of bug squashing, and enough +opportunities to get the feeling of the Debian Project's dynamics. Not +to mention it's a very fun blend to work on!

+ +

Derived from the previous statement, is the delay in catching up +with the main Debian release and documentation. This is common though +to all blends and derivatives, but it's an issue we can all work +on.

+ +

Which free software do you use daily?

+ +

I can hardly imagine myself spending a day without Vim, since my +daily routine covers writing code and hacking configuration files. I +am a fan of the Awesome window manager (but I also like the +Enlightenment project a lot!), +Claws Mail due to its ease of +use and very configurable behaviour. Recently I fell in love with +Redshift, which helps me +get through the night without headaches. Of course, there is much more +stuff in this bag, but I'll need a blog on my own for doing this!

+ +

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

+ +

Well, on this field, I cannot do much more than experiment right +now. So, being far from having a recipe for success, I can only assume +that:

+ +
    + +
  • schools would like to get rid of proprietary software
    • + +
  • students will love the openness of the system, and will want to + experiment with it - maybe we need to harvest the native curiosity + of teenagers more?
    • + +
  • there is no "right one" when it comes to strategies, but it would + be useful to have some success stories published somewhere, so + other can get some inspiration from them (I know I'd promote + them!)
    • + +
  • more active promotion - talks, conferences, even small school + lectures can do magical things if they encounter at least one + person interested. Who knows who that person might be? ;-)
    • + +
+ +

I also see some problems in getting Skolelinux into schools; for +example, in our country we have a great deal of corruption issues, so +it might be hard(er) to fight against proprietary solutions. Also, +people who relied on commercial software for all their lives, would be +very hard to convert against their will.

Typesetting a short story using docbook for PDF, HTML and EPUB
-
24th March 2013
-

A few days ago, during a discussion in -EFN about interesting books to read -about copyright and the data retention directive, a suggestion to read -the 1968 short story Kodémus by -Tore Åge Bringsværd -came up. The text was only available in old paper books, and thus not -easily available for current and future generations. Some of the -people participating in the discussion contacted the author, and -reported back 2013-03-19 that the author was OK with releasing the -short story using a Creative -Commons license. The text was quickly scanned and OCR-ed, and we -were ready to start on the editing and typesetting.

- -

As I already had some experience formatting text in my project to -provide a Norwegian version of the Free Culture book by Lawrence -Lessig, I chipped in and set up a -DocBook processing framework to -generate PDF, HTML and EPUB version of the short story. The tools to -transform DocBook to different formats are already in my Linux -distribution of choice, Debian, so -all I had to do was to use the -dblatex, -dbtoepub -and xmlto tools to do the -conversion. After a few days, we decided to replace dblatex with -xsltproc/fop (aka -docbook-xsl), -to get the copyright information to show up in the PDF and to get a -nicer <variablelist> typesetting, but that is just a minor -technical detail.

- -

There were a few challenges, of course. We want to typeset the -short story to look like the original, and that require fairly good -control over the layout. The original short story have three -parts/scenes separated by a single horizontally centred star (*), and -the paragraphs do not contain only flowing text, but dialogs and text -that started on a new line in the middle of the paragraph.

- -

I initially solved the first challenge by using a paragraph with a -single star in it, ie <para>*</para>, but it made sure a -placeholder indicated where the scene shifted. This did not look too -good without the centring. The next approach was to create a new -preprocessor directive <?newscene?>, mapping to "<hr/>" -for HTML and "<fo:block text-align="center"><fo:leader -leader-pattern="rule" rule-thickness="0.5pt"/></fo:block>" -for FO/PDF output (did not try to implement this in dblatex, as we had -switched at this time). The HTML XSL file looked like this:

- -

-<?xml version='1.0'?> 
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
-  <xsl:template match="processing-instruction('newscene')">
-    <hr/>
-  </xsl:template>
-</xsl:stylesheet> 
-

- -

And the FO/PDF XSL file looked like this:

- -

-<?xml version='1.0'?> 
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
-  <xsl:template match="processing-instruction('newscene')">
-    <fo:block text-align="center">
-      <fo:leader leader-pattern="rule" rule-thickness="0.5pt"/>
-    </fo:block>
-  </xsl:template>
-</xsl:stylesheet> 
-

- -

Finally, I came across the <bridgehead> tag, which seem to be -a good fit for the task at hand, and I replaced <?newscene?> -with <bridgehead>*</bridgehead>. It isn't centred, but we -can fix it with some XSL rule if the current visual layout isn't -enough.

I did not find a good DocBook compliant way to solve the -linebreak/paragraph challenge, so I ended up creating a new processor -directive <?linebreak?>, mapping to <br/> in HTML, and -<fo:block/> in FO/PDF. I suspect there are better ways to do -this, and welcome ideas and patches on github. The HTML XSL file now -look like this:

- -

-<?xml version='1.0'?> 
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
-  <xsl:template match="processing-instruction('linebreak)">
-    <br/>
-  </xsl:template>
-</xsl:stylesheet> 
-

- -

And the FO/PDF XSL file looked like this:

- -

-<?xml version='1.0'?> 
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'
-  xmlns:fo="http://www.w3.org/1999/XSL/Format">
-  <xsl:template match="processing-instruction('linebreak)">
-    <fo:block/>
-  </xsl:template>
-</xsl:stylesheet> 
-

One unsolved challenge is our wish to expose different ISBN numbers -per publication format, while keeping all of them in some conditional -structure in the DocBook source. No idea how to do this, so we ended -up listing all the ISBN numbers next to their format in the colophon -page.

If you want to check out the finished result, check out the -source repository at -github -(future/new/official -repository). We expect it to be ready and announced in a few -days.

Debian Edu interview: Jonathan Carter
+
12th June 2013
+

There is a certain cross-over between the +Debian Edu / Skolelinux +project and the Edubuntu +project, and for example the LTSP packages in Debian are a joint +effort between the projects. One person with a foot in both camps is +Jonathan Carter, which I am now happy to present to you.

+ +

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

+ +

I'm a South-African free software geek who lives in Cape Town. My +days vary quite a bit since I'm involved in too many things. As I'm +getting older I'm learning how to focus a bit more :)

+ +

I'm also an Edubuntu contributor and I love when there are +opportunities for the Edubuntu and Debian Edu projects to benefit from +each other.

+ +

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

+ +

I've been somewhat familiar with the project before, but I think my +first direct exposure to the project was when I met Petter +[Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in 2005 in +London. They provided great feedback that helped the bootstrapping of +Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and +it was great getting input from people who have been around longer. I +was also still very excitable and said yes to everything and to this +day I have a big todo list backlog that I'm catching up with. I think +over the years the relationship between Edubuntu and Debian-Edu has +been gradually improving, although I think there's a lot that we could +still improve on in terms of working together on packages. I'm sure +we'll get there one day.

+ +

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

+ +

Debian itself already has so many advantages. I could go on about +it for pages, but in essence I love that it's a very honest project +that puts its users first with no hidden agendas and also produces +very high quality work.

+ +

I think the advantage of Debian Edu is that it makes many common +set-up tasks simpler so that administrators can get up and running +with a lot less effort and frustration. At the same time I think it +helps to standardise installations in schools so that it's easier for +community members and commercial suppliers to support.

+ +

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

+ +

I had to re-type this one a few times because I'm trying to +separate "disadvantages" from "areas that need improvement" (which is +what I originally rambled on about)

+ +

The biggest disadvantage I can think of is lack of manpower. The +project could do so much more if there were more good contributors. I +think some of the problems are external too. Free software and free +content in education is a no-brainer but it takes some time to catch +on. When you've been working with the same proprietary eco-system for +years and have gotten used to it, it can be hard to adjust to some +concepts in the free software world. It would be nice if there were +more Debian Edu consultants across the world. I'd love to be one +myself but I'm already so over-committed that it's just not possible +currently.

+ +

I think the best short-term solution to that large-scale problem is +for schools to be pro-active and share their experiences and grow +their skills in-house. I'm often saddened to see how much money +educational institutions spend on 3rd party solutions that they don't +have access to after the service has ended and they could've gotten so +much more value otherwise by being more self-sustainable and +autonomous.

+ +

Which free software do you use daily?

+ +

My main laptop dual-boots between Debian and Windows 7. I was +Windows free for years but started dual-booting again last year for +some games which help me focus and relax (Starcraft II in +particular). Gaming support on Linux is improving in leaps and bounds +so I suppose I'll soon be able to regain that disk space :)

+ +

Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi, +git, Tomboy, KVM, VLC and LibreOffice. Recently I've been torn on +which desktop environment I like and I'm taking some refuge in Xfce +while I figure that out. I like tools that keep things simple. I enjoy +Python and shell scripting. I went to an Arduino workshop recently and +it was awesome seeing how easy and simple the IDE software was to get +up and running in Debian compared to the users running Windows and OS +X.

+ +

I also use mc which some people frown upon slightly. I got used to +using Norton Commander in the early 90's and it stuck (I think the +people who sneer at it is just jealous that they don't know how to use +it :p) + +

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

+ +

I think trying to force it is unproductive. I also think that in +many cases it's appropriate for schools to use non-free systems and I +don't think that there's any particular moral or ethical problem with +that.

+ +

I do think though that free software can already solve so so many +problems in educational institutions and it's just a shame not taking +advantage of that.

+ +

I also think that some curricula need serious review. For example, +some areas of the world rely heavily on very specific versions of MS +Office, teaching students to parrot menu items instead of learning the +general concepts. I think that's very unproductive because firstly, MS +Office's interface changes drastically every few years and on top of +that it also locks in a generation to a product that might not be the +best solution for them.

+ +

To answer your question, I believe that the right strategy is to +educate and inform, giving someone the information they require to +make a decision that would work for them.
