Neste mann ut er Marius Kotsbak, styremedlem i
-FRISK og mangeårig
-bidragsyter i
-Skolelinux-prosjektet.
-
-
Hvem er du, og hva driver du med til daglig?
-
-
Jeg er en systemutvikler/kybernetiker og jobber med dette til
-daglig. PÃ¥ fritiden tester jeg ut/bruker mye fri programvare, og
-bidrar med testing og utvikling når jeg ser stort nok behov for det og
-jeg har noe å bidra med.
-
-
Hvordan kom du i kontakt med Skolelinux-prosjektet?
-
-
Hmm, det er lenge siden, så det er nesten så jeg ikke husker. Jeg
-hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
-opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
-skoler i nærområdet med å installere Skolelinux og finne brukt
-IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
-Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
-klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
-på skolene, kun med kostnaden til servere.
-
-
Hva er fordelene med Skolelinux slik du ser det?
-
-
Det er et system spesielt skreddersydd for drift av et stort antall
-klienter mot servere, og da spesielt i henhold til skolers behov. Det
-er enkelt og billig å installere og drifte, og det trenger ikke ny
-maskinvare for god ytelse.
-
-
Hva er ulempene med Skolelinux slik du ser det?
-
-
Hardwarestøtten kunne vært bedre og i enda større grad
-installerbart rett ut av boksen. Distribusjonen har til tider hatt
-litt gammel programvare pga. at den følger Debian sine utgivelser.
-Kanskje man skulle vurdert en versjon basert på Ubuntu eller andre
-distribusjoner i tillegg?
-
-
Hvilken fri programvare bruker du til daglig?
-
-
Oi, det er ikke lite. Her er det jeg kommer på i farta. Jeg bruker
-Linux og Ubuntu, og på Ubuntu programene Firefox, Thunderbird,
-Chromium, Pidgin, Digikam, OpenOffice, Wireshark, git og irssi.
-Telefonen min er en Android, og der bruker jeg programmene K-9 Mail,
-OI Shopping list, Shuffle, ZXing, OI Notepad og ADW Desktop. PÃ¥ jobb
-bruker jeg JBoss, Eclipse, uCLinux for Blackfin, RCF-CPP, Qt, Maven,
-og boost-bibliotekene for C++.
-
-
Hvilken strategi tror du er den rette å bruke for å få
-skoler til å ta i bruk fri programvare?
-
-
En bør fokusere på totalkostnader inkludert driftsbehov,
-fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
-lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
-fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
-elevene. En bør også forbedre den fri programvaren ved testing,
-bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
-uten at man har forsikret seg at den har tilstrekkelig kvalitet,
-ellers kan man lett oppnå det motsatte. Tror en bør selge inn
-konseptet til fylkes-/statsnivå, kanskje med bidrag til
-utviklingsarbeid fra disse som alle landets skoler kan få glede
-av.

In the Debian boot system, several packages include scripts that
+are started from /etc/rcS.d/. In fact, there is a bite more of them
+than make sense, and this causes a few problems. What kind of
+problems, you might ask. There are at least two problems. The first
+is that it is not possible to recover a machine after switching to
+runlevel 1. One need to actually reboot to get the machine back to
+the expected state. The other is that single user boot will sometimes
+run into problems because some of the subsystems are activated before
+the root login is presented, causing problems when trying to recover a
+machine from a problem in that subsystem. A minor additional point is
+that moving more scripts out of rcS.d/ and into the other rc#.d/
+directories will increase the amount of scripts that can run in
+parallel during boot, and thus decrease the boot time.
+
+
So, which scripts should start from rcS.d/. In short, only the
+scripts that _have_ to execute before the root login prompt is
+presented during a single user boot should go there. Everything else
+should go into the numeric runlevels. This means things like
+lm-sensors, fuse and x11-common should not run from rcS.d, but from
+the numeric runlevels. Today in Debian, there are around 115 init.d
+scripts that are started from rcS.d/, and most of them should be moved
+out. Do your package have one of them? Please help us make single
+user and runlevel 1 better by moving it.
+
+
Scripts setting up the screen, keyboard, system partitions
+etc. should still be started from rcS.d/, but there is for example no
+need to have the network enabled before the single user login prompt
+is presented.
+
+
As always, things are not so easy to fix as they sound. To keep
+Debian systems working while scripts migrate and during upgrades, the
+scripts need to be moved from rcS.d/ to rc2.d/ in reverse dependency
+order, ie the scripts that nothing in rcS.d/ depend on can be moved,
+and the next ones can only be moved when their dependencies have been
+moved first. This migration must be done sequentially while we ensure
+that the package system upgrade packages in the right order to keep
+the system state correct. This will require some coordination when it
+comes to network related packages, but most of the packages with
+scripts that should migrate do not have anything in rcS.d/ depending
+on them. Some packages have already been updated, like the sudo
+package, while others are still left to do. I wish I had time to work
+on this myself, but real live constrains make it unlikely that I will
+find time to push this forward.

The Gnash project is still
-the most promising solution for a Free Software Flash implementation.
-A few days ago the project
-announced
-that it will participate in Google Summer of Code. I hope many
-students apply, and that some of them succeed in getting AVM2 support
-into Gnash.

While at Debconf11, I have several times during discussions
+mentioned the issues I believe should be improved in Debian for its
+desktop to be useful for more people. The use case for this is my
+parents, which are currently running Kubuntu which solve the
+issues.
+
+
I suspect these four missing features are not very hard to
+implement. After all, they are present in Ubuntu, so if we wanted to
+do this in Debian we would have a source.
+
+
+
+- Simple GUI based upgrade of packages. When there
+are new packages available for upgrades, a icon in the KDE status bar
+indicate this, and clicking on it will activate the simple upgrade
+tool to handle it. I have no problem guiding both of my parents
+through the process over the phone. If a kernel reboot is required,
+this too is indicated by the status bars and the upgrade tool. Last
+time I checked, nothing with the same features was working in KDE in
+Debian.
+
+- Simple handling of missing Firefox browser
+plugins. When the browser encounter a MIME type it do not
+currently have a handler for, it will ask the user if the system
+should search for a package that would add support for this MIME type,
+and if the user say yes, the APT sources will be searched for packages
+advertising the MIME type in their control file (visible in the
+Packages file in the APT archive). If one or more packages are found,
+it is a simple click of the mouse to add support for the missing mime
+type. If the package require the user to accept some non-free
+license, this is explained to the user. The entire process make it
+more clear to the user why something do not work in the browser, and
+make the chances higher for the user to blame the web page authors and
+not the browser for any missing features.
+
+- Simple handling of missing multimedia codec/format
+handlers. When the media players encounter a format or codec
+it is not supporting, a dialog pop up asking the user if the system
+should search for a package that would add support for it. This
+happen with things like MP3, Windows Media or H.264. The selection
+and installation procedure is very similar to the Firefox browser
+plugin handling. This is as far as I know implemented using a
+gstreamer hook. The end result is that the user easily get access to
+the codecs that are present from the APT archives available, while
+explaining more on why a given format is unsupported by Ubuntu.
+
+- Better browser handling of some MIME types. When
+displaying a text/plain file in my Debian browser, it will propose to
+start emacs to show it. If I remember correctly, when doing the same
+in Kunbutu it show the file as a text file in the browser. At least I
+know Opera will show text files within the browser. I much prefer the
+latter behaviour.
+
+
+
+
There are other nice features as well, like the simplified suite
+upgrader, but given that I am the one mostly doing the dist-upgrade,
+it do not matter much.
+
+
I really hope we could get these features in place for the next
+Debian release. It would require the coordinated effort of several
+maintainers, but would make the end user experience a lot better.
