11th of July in HEL

The first thing I really noticed in the morning was that I missed the breakfast, again.
On the other hand this wall in the cafeteria caught my lens - this is a clock up in the air, aprox. 3-4 meters up from the floor. Now that you know, where it is, notice the power plugs ... I mean ... why???

Soon after that I got the chance to play around with the new Nokia 770 toy. It really is a marvel - beautiful software, great hardware. You can see it here accessing the Slashdot over GPRS.

One of the talks I've been more interested in was the CDD talk by Andreas Tille (see my other blog entery about it):

I didn't take many photos this day, so this one gets into top packages - this is the cafeteria full with Debian Developers over the dinner time.

Soon after that I went to the dorm room to do some UI prototyping in Glade for my SoC project, but I was too tired and I had to go to sleep after a couple of hours.

CDD ideas

I am now at the speach of Andreas Tille about CDDs and let me dump here my idea, what the CDD framerowk should do.

  • it should be enough to write one structured text file to create a CDD
  • you can select a set of packages that are: needed, recommended, conflicted;
  • you can preseed debconf database with answers;
  • you can do some specific changes to the conffiles or other files (as diffs or rewrite rules);
  • you can add/remove some text or binary files;
  • you can recompile a package (with a patch);
  • you can add some package that is not yet in Debian;
  • the framework can generate a set of packages that could be uploaded to Debian, to allow a Debian user to 'apt-get install cdd-something'
  • the framework can generate a simplified installation CD that installs the CDD with a minimum amount of questions
  • the framework can generate a LiveCD with the CDD
  • a summary of bug reports that relate to the CDD should be gettable
  • all the actions for a CDD should be possible to be done on Debian infrastructure. portal with standartized interfaces for every CDD for documentation, information, bug summaries, cvs/arch/svn/... links, links to all CDs, links to web forums, ...
  • all the actions for a CDD should be possible to be done fully independently from Debian. Packages for that should be inside Debian and should be easy to install/configure
  • a CDD must be able to do releases independantly from Debian
  • the should be a way to do security updates for all relased CDDs for some fixed time period
  • any CDD could be derrived either from plain Debian of from any other CDD
  • The feature set must be complete enough to have Ubuntu as a CDD
  • I will add more, once I remember more ideas.

    Delayed photoblog - July 10

    This day is rich on pictures - 8 of them got in here, but that is a bit compensated by low number of photos tomorrow :)
    Here is a photo of the cafeteria where all meal are served at the Debconf. It is not a bomb bunker.

    This is the breakfast of mine for the day. You might wonder - why does that look so much like a lunch? Because it is. I missed the breakfast and only woke up at lunch. Doh.

    And the I arrived at the talks and the first thing that I see on the screen is ...

    Branden followed that up with a detailed talk about man pages. You can now also see that debconf2x-man generates better man pages then the first version.

    The talk by Enriko was also very interesting, but despite being a bit sleepy, he moved so fast all the time, that I have no usable picture of him :(
    Going back to Smokki we went by 'the lost band':

    Here is a very bad attempt of mine to make a panoramic photo of the Smokki hacklab:

    Many people wondered, why the hacklab webcam vibrates while going right and left. Here you can see it:

    After the long hacking hours, many developers like to relax and have some kind of movement, for example like this:

    Also sauna is an option. Today sauna was particulary good as it was finnaly turned up to 100 C, like I asked for the last two days :)

    DC5 - Jul 9

    After some nice breakfast, the Debian Day started with an address from the leader.

    Jaldhar H. Vyas did a nice talk about the Debian in general, touching a lot of later subjects too - due to some technical problems, he had to go without his slides:

    Then Gunnar Wolf did a talk about free software, where he also touched on the patent issues. After that my talk was up. While the video team was trying to get a nicer display of my presentation on the complex presentation system of the room, I introduced myself and noted my involvement with the swpat issues in EU. After the applause stopped, the hardware was ready and I could start with my talk. It went very well despite being prepared the night before - the CDD possible relationship with Ubuntu inspired some ideas that, I hope, will make Ubuntu into a kind of CDD.

    Here is a picture of internals of the CS department building that the talks are happening in. You can see that the weather here is just perfect.

    Alexander Schmehl's speach about involvement into Debian as an end-user was even more funny then expected because of repeated and different hardware failures of the presentation beamer control system and attempts of the video team to repair it. I didn't manage to get a clear picture of Alex banging his head against the blackboard, but this face expression of his is allmost as good, but see the video for the best effect. :D

    After that allmost all DDs went to the Smokki hacklab to do some hacking. Here we can see some GAIM hacking in progress :)

    Later in the evening there was a great game of Ultimate (5 on 5). I was on the same team as Mark Shuttleworth and I participated in all scorings from our team, but the problem was that there was not too many of those. While we didn't keep the score (this game is very exhausting), our team definately lost :(. After that the Ultimate players occupied the sauna - Ultimate Sauna was that. It was quite fun despite the low temperature. No photos from there, again. :)

    1.08 Euro?!?!

    This will not wait until the daily summary: in Extremadura all mainterance costs of all LinEx distributions, including a dedicated system administrator in every school and including three developers only cost them 1.08 euro per computer per year !!!
    This is simply fenomenal.

    Debconf - first day + morning

    Let us try out a photoblogging format for the daily Debconf5 reportings.
    I only arrived here yesterday and here is the schedule of the bus from the center of Helsinki to the campus region:

    After following the many friendly signs, I arrived to the site and spotted the first developers:

    Some more were just around the corner:

    After trying to start the wireless according to several mystical HowTo's and giving up after two hours, I had to plug myself into the Ethernet jack in the dorm room and start working on the presentation for tomorrow. Actually I was not the only one doing that on the last night - developers are lazy :)

    The night was long and funny

    Around 70 developers were said to have arrived on this day

    No photos from the dorm sauna, sorry :)

    In the morning we only got up half an hour before the end of the breakfast - around 8:30.

    Anime night

    A couple of days ago I was at an event of the local anime society - half a night of anime. The selected movies were really psyhic. It started with a simple and easy "She and her cat", continued with a nice and romantic "Voices of a distant star" and then went into overdrive with "1001 night", "Perfect Blue", "Cat soup" and "Tales of the Labyrinth". In the end there was a chillout period with "Ghiblis" and another version of "She and her cat".

    As that was not enough for us - we went for an afterparty: watching "Fruit basket" 'till the morning :D

    Slow and Strange hangs

    Yesterday I started to try to configure my desktop and my notebook to talk to each other via wireless using the AdHoc mode. The results were far from good - the best I could get, after few hours of desperate hacking around, was a working link with 100 Kbit/s.
    The best thing was that my desktop started behaving erratically - almost all programs started to have strange 2 minute hangs all the time. Strace showed that they tried to connect to the portmapper. Disabling, enabling or even removing the portmapper didn't help. After much head bumping I traced the culpit back to a SNAT statement that I put up to allow my notebook to get some Internet - I appeared to SNAT all localhost connections and they had to timeout instead of getting an instant 'Connection refused'.

    Return from BXL

    When I came back from Brussels, my bag went missing in the airport. It seams that BXL airport folks lost a trolley or something, as I was not alone in this. The airport people took my phone number, home address, tag and ticket numbers and a description of the bag.
    The next day they called in to say that they found it. In a half an hour a delivery man from the airport came to my house to bring my bag.
    All well what ends well.
