Sebastian Trüg on K3b 1.0 and More
==================================

   Today we talk with the author of the K3b Project, the well known
application that lets you burn CDs/DVDs and that lets you rip music from
CD audio and films from DVD Video. We are going  to talk with Sebastian
about his story: when he started using KDE, when he started to create
K3b and to talk about his plans in KDE 4 with a new KDE 4 project.  This
interview was originally released
[http://www.kde-it.org/index.php?option=com_content&task=view&id=108&Itemid=1]
for KDE Italia.

     Hello Sebastian. What did you think when I asked you an interview
for KDE Italia? Oh man, yet another interview? ;) No, really, I am
honored to be of interest to you as an interview partner.

     Can you introduce yourself to the KDE Italia readers? What did you
study? What is your day job? Originally I come from the north of Germany
where I was raised in rainy weather. Once I finished school I "fled" to
the south of Germany to study computer science in Freiburg. It is hard
to go more south than Freiburg if you want to stay in Germany. Since
August of last year I am working for Edge-IT, a subsidiary of Mandriva.
I am still living in Freiburg working remotely from home. It is great. I
finally can do what I like best and get payed for it: working on KDE
software. In particular the Nepomuk-KDE project
[http://nepomuk-kde.semanticdesktop.org/] which is part of Nepomuk, the
European semantic desktop initiative.
     When did you hear of KDE for the first time? I think it was in
1997. When I came to Freiburg a friend "introduced" me to SuSE
5.something or 4.foobar. It came with KDE 1 and Qt 1.4. In the beginning
I was not really interested since I did no programming yet. Then I
started to learn Qt development in a software project we did at the
university and I got hooked.

     How and when did you get involved in KDE? My interest in Qt started
with the software project mentioned above. If I recall it correctly that
was the time when I really began to try Linux/KDE. It was still KDE 1.4
back then and the desktop was by far not as powerful and nice as it is
today. I wanted to see if I could do everything I normally did on my
Windows system (which was not much ;) on Linux. The first thing that did
not work as I wanted it to was CD burning. Especially Audio CD burning
was near to impossible with the existing tools. I wanted to drag my mp3
files somewhere and click a few buttons, not manually decode the files
using mpg123 and then burn the CD on the commandline or use something
like xcdroast or kcreatecd. These tools simply did not provide what I
needed. So I asked myself: "Why don't you try it yourself?" And I did.
The first version of K3b I released was 0.3.1 and with it the at times
strange K3b versioning system started. It was very well received and I
just kept going.

     What makes you develop for KDE instead of the competition? Easy: Qt
and the KDE libs. IMHO Qt is the best widget-library there is. It's
easy, it's powerful, and it looks good. And the kdelibs are very well
designed and solve so many standard problems so as a developer I can
focus on the really important stuff in my application. And in the end
"real programming" can only be done with C++. ;)

     Can you say that programming for KDE was an investment? You got
C++/Qt programming experience that helped you in enriching your personal
skill set. Can this be of help getting a job? Could it be a good
attribute to take to a job interview with a software company? K3b was
without a doubt my ticket into the professional world. It built a nice
reputation and raised a lot of interest. I surely would not have my
current job if I would never have done K3b.

     Can you explain what "DVD authoring" is? Some users said K3b does
"DVD authoring". You are the K3b author so no one better than you can
tell us. This is a really strange question. You must be talking about
Video DVD because otherwise it would just be burning DVDs. And authoring
Video DVDs means preparing the movie material, cutting it, adding
subtitles, creating a menu. K3b can do none of those things. So, no, I
am not the best one to talk to about Video DVD authoring. Maybe I will
be some day when I start implementing it in K3b but that is nearly as
much work as all of K3b was until now.

     What are the more important new K3b features shipped with the
version 1.0? The most important new feature for me is the K3b
MediaCache. It knows at all times which medium is in which drive and
thus, provides a basis for a much improved user feedback and GUI
adjustments. One example is the CD copy dialogue: K3b now only shows the
settings suitable for the inserted source medium. If you copy an audio
CD you only get the audio copy options. It also provides a means to
automatically adjust the project size to the inserted writable medium.
Then there is the new Video DVD ripping. It provides a very easy way to
encode Video DVD titles to MPEG4 (for example Xvid) movies. The user
interface is quite similar to the audio CD ripping and is focused on
simplicity. It is by far not as powerful as for example DVD:Rip but it
is easy to use.

     Was in the past K3b part of the standard KDE modules? K3b was once
in the kdemultimedia package but only for a very short time. It was
never released with kdemultimedia. Frankly. I am glad we moved it out of
there and into the Extragear because I could never have kept up with the
kdemultimedia release cycle. K3b needs many little bugfix releases due
to the many different CD and DVD devices that all behave a little
different and I cannot test all of them because I don't have them all
(actually I tried getting testing devices from many companies, but apart
from LG I never received any). So Extragear is actually the perfect
place for K3b.

     Is it true that some people wanted K3b in KDE 4 standard modules?
Is this possible or not? I never heard anyone ask K3b to become part of
KDE4. In theory it is possible but I really don't want it to. I like the
freedom I have with K3b. This way I have my own release cycle and I can
change whatever I want, whenever I want. After all it is not clear which
advantage would come from putting K3b into KDE4 itself. A tighter
integration with other applications can also be achieved with K3b being
a separate package. KDELibs and KDE-Parts bless.

     When do you think to release next K3b versions (1.0.2, ...)? When
do you start KDE 4 porting? I am now preparing 1.0.2 which will fix all
the bugs the "real" users find in 1.0 and 1.0.1. In the end all those
previews and release candidates have only been tested by geeks like me
and we are not the best when it comes to exploiting bugs. After K3b 1.1
I will start porting K3b to KDE 4 libraries.

     Are you being paid to work on KDE? Until last August when I started
working for Edge-IT I did all the work on K3b in my spare time except
for a three-month internship for SuSE. Now, however, I am working
full-time on KDE, namely the Nepomuk-KDE project as mentioned before.

     I've seen in your commit and from some news around the web you are
working on a new KDE project. It's related to KDE 4. Nepomuk. Can you
talk about it? Sure. Nepomuk-KDE is a subproject of the European
research project Nepomuk. The goal is to implement the standards and
technologies defined there on the KDE desktop. I will not try to explain
the whole Nepomuk project here but focus on the part that I do for KDE
at the moment. The keyword is metadata. At the moment the only metadata
handled in KDE is what you can extract from files, for example id3 tags
in an mp3 file, and maybe some tags and ratings specific to certain
applications. Nepomuk-KDE (Hopefully it will soon get a fancy new name)
aims to unify the access to metadata for all applications. Applications
will have the possibility to create and retrieve metadata from one
central storage. Imagine for example that you want to find all resources
related to a certain person. With Nepomuk-KDE you will then get the
KAddressbook entry, all the emails the person has written, the emails
you wrote to the person, maybe the images the person took, or those that
show the person and most importantly second-degree resources like the
pdf document that person sent you. The idea is that metadata (and I am
not talking about the metadata already contained in files which is
extracted and indexed by systems like Strigi or Beagle) is created by
basicaly all KDE applications and interconnected automatically or
semi-automatically.

     How would you define your experience with KDE and KDE developers?
Did you meet any of them personally or you just know them by emails? The
first time I met some of the KDE guys was at last year's Akademy. Before
that all contact was through email, I never even went in to the IRC.
Today I know that you have to do that in order to stay connected. And
now that I know some of the nice KDE faces personally chatting became
much more interesting.

     Have you ever stayed at an Akademy? If so can you tell us briefly
how it was? What did you do? Do you think a KDE user/developer has to
participate at least once to the KDE developers conference (Akademy) in
his/her life? As I said: I participated in last year's Akademy. It was a
very nice experience and I think that it makes a lot of sense to go
there every year if you want to be part of KDE. Working together is much
easier if you know the people personally. This year, however, I won't be
able to attend the Akademy since I am getting married at the exact same
time in France.

     Oh, than many wishes :D . Do your parents and friends use Linux and
KDE? My girlfriend surely uses KDE. She actually uses it in a way that
she misses a lot of the great functionality when she sits in front of a
Windows machine.

     What could be your slogan to attract people to KDE? Can you give
also some "reasons to stay with *nix/KDE"? "Come on, use KDE, please....
PLEASE!" (Man, I should have gone into advertising!)

     If, one day, you stopped working on KDE, what could be the reason?
Too much time to dedicate to a new job, to your family or what else? Or,
simply, your passion for KDE is spent and so you leave the KDE team?
What would you miss of the KDE experience? (Obviously we hope you can
work in the KDE team for at least the next 30 years :)) How should I
know what I will be doing in the future. But I would probably miss
creating something. When I was a child I created stuff with Lego, now I
am a programmer. Actually, I don't think it is important what I create.
I just need to create something that is usable and impresses people.
When I was little my Lego models were usable too since I played with
them and my parents were impressed by them. Today the software I write
is usable to a lot of people and many are impressed by it.

     How much time do you usually spend on KDE? All of it. ;) Well,
probably 8 hours a day.

     What was your first Linux distribution? Did you try many ones
before you found the right one? I started with SuSE. Later I tried many
more. I actually have installations of many different for testing
purposes.

     Which distribution do you use now? Why? On my laptop I am running
Mandriva Cooker and not only because they pay me to do so. It actually
works perfect and as far as rpm goes I know of nothing fancier then
urpmi. My big machine at home runs Gentoo because I like compiling stuff
and having an optimised system.

     What is your favourite place in the world? I haven't found that yet
(No, it just can't be in front of the computer screen! ;)

     Have you ever been in Italy? If not, do you plan to come here and
visit our country? Sure I have been to Italy. Many times.... ok, once,
when I still was in school. But I loved it and who wouldn't? It is warm
almost all the time.

     Thank you for your time and good luck with K3b and Nepomuk. I think
they're two of the best apps written for KDE. Thanks a lot for the
interview.
