Great concert, little short maybe, but well… Making it longer won’t make it long enough :)

The setlist was something like this (taken from a gig in Danmark, changed where I knew the differences):

• KGB
• Delikatessen
• Knekker deg til sist
• Hevnervals
• Container
• Señor Flamingos Adieu
• Blitzregn Baby
• Bøn Fra Helvete
• Mann Mot Mann
• Kontroll På Kontinentet
• Christiania (yes, the self-governed community in Denmark, but also the former name of Oslo)
• På Ditt Skift
• Die Polizei (request from audience)
• Di Grind
• Dieter Meyers Institution
• Evig Pint
• Ompa til Du dør
• Maestro

Reprise:

• Mr. Kaizer…
• Bak et Halleluja
• Resistansen

Thanks to Lotte, Sjoerd, and Bram for joining me. Ah, and Lowlands is a no go, since I’ll be in Iceland by then after all (I thought Lowlands was in July).

And I found some English translations to the lyrics!

Ooooh, my first visualization application!

For the course Visualization I write a fluids flow visualization. Based on some sample code and a simulation, this little beast already miaows a bit. We had smoke and hedgehogs, two fairly standard techniques in visualization. It shows you the density and direction of the flow of a fluid (or gas if you like) when you inject some fluid in it (using your mouse in this simulation).

By the way, the whole thing is animated of course.

The two standard visualizations

Now I added streamlines, another technique. Currently it uses Euler’s numerical integration, which is fairly inaccurate for this application. I think I’ll have to change it before I hand it in.

The newly added visualization

There is this little problem with streamlines; you don’t know in advance where they will end up. Thus you’ll never know whether you cover an area well enough to be able to say something about it. Maybe there are some clever algorithms that can, but we should probably look into something else.

Combining all three techniques is pretty, but completely useless!

Coming up: Isolines. You know, the things you see on the weather map indicating areas with the same air pressure, well here it will be matter density, but the idea remains the same of course. They are much easier to evenly distribute them over the whole image, but are a bit harder to construct.

Update: People wanted to play with it already, so I made a fluids-0.0.0 release.

Finally, after having Hoefnix for more than a year, I’m booting Linux on my Mac more and more often. There were a few reasons I sticked to OS X, one of them was I didn’t really had a reason to over to Linux; everything worked for me… Well, sort of, I’m getting fed up with looking for warez and shit while there is an enormous repository of Free Software in the world just waiting to be discovered and used.

The course of Visualization led me back to Linux, since the libraries that I needed aren’t available in DarwinPorts at the time and they are in Debian, which is just so much easier. Gotta love a good package management system :-)

So now I’m dualbooting again, like in the old days with Windows and Linux. Basically for all the imaging stuff I use OS X. Ah, and for Democracy TV of course (Linux player still in very early alpha).

Carnaval is well over by now. In the Netherlands, it is fairly common for a city to have a different name, I was in Breda at my parents’, which is called Kielegat during Carnaval.

Sunday was the big parade in Prinsenbeek or better: Boemeldonck. Prinsenbeek is a village (population 11.000) right next to Breda and it has a large tradition of carnaval. Everyone seems to be in some way connected to the celebrations, via one of the many carnaval clubs, or active in the organization of activities during carnaval.

Yes, well, actually it’s been almost a month now since we came back from Edinburgh, but I didn’t want to post without pictures being online and I had to edit them plus I didn’t have a decent piece of photo gallery software.

But now I do! It is called p.hot.os and it is going to be my photo gallery page, so here it is, the post on Edinburgh.

Actually, p.hot.os is nothing more than webgen with a custom gallery layouter (and you can even do without that one). So, basically, I now use webgen for my gallery needs! Please tell me what you think of it, I still have some ideas to implement (for instance something with Google Maps, like most of you probably already saw in my Coppermine gallery).

So, back to Edinburgh… Uhm, I’m back from Edinburgh and it was a great weekend. We saw a lot of the city and got a hint of its surroundings, took a lot of pictures, but didn’t get on the 41 however. I’d like to thank you, Paul, for your hospitality and hope to see you soon (in a few minutes, since you’re coming home at the moment I’m writing this).

It’s good to be prepared when going on a trip to Edinburgh, so, which LRT bus are you?

Which LRT bus route are you?

To all who read this, a happy new year. Just came back from family.

Looks a bit fuzzy, huh? Next time I should probably try to focus better

Bit late maybe (we’re already in week 4), but here’s the list of courses of this trimester.

• Proving with computer assistance (assignment + exam)
• Advanced algorithms (assignment + paper)
• Heuristic search (exam)
• Visualization (assignment)
• Requirement analysis, design and verification (exam + assignment)
• Wiskunde 4 (exam)

Well, then there still are those three assignment courses…

• History of Computing assignment still needs a subject.
• The Linux Operating System assignment.
• Hypermedia Systems assignment will be started after having read all the course hypertext.

Well, it is truly dead then

Serenity, may you light your fire in our hearts and fly forever (bweh, that’s cheesy).

Created a del.icio.us account and imported all of my bookmarks. I’ll probably still have to retag stuff and make the titles somewhat better. Now if there would be a browser plugin which in realtime fetches the bookmarks and if you add them locally they will get submitted…

Nope, I have nothing to do with the del.icio.us power outage just hours after I created the account ;-)

I also updated my Technorati profile – yeah, I have such a thing, still dunno why – to the “new” location of the journal. There I found out that I apparantly had dinner with some Austrian guy last October :-)

Today (yesterday if you like) Utopia held its annual HCC Dagen meeting!

The number of merchants was saddingly low, they even had to close down two half halls (and the worst: the most interesting stuff was traditionally in those two halls). I fear for the existence of the current setup; the goods the shops had to offer was thirteen-in-a-dozen standard stuff and all the same.

Where did the times go where you could find the most obscure hardware at the HCC Dagen? Where were the big companies like Philips? Intel had a modest stand. Even Microsoft didn’t have a big over-the-top stand this year. Not that I was in any way interested in those, but they bring a lot of money in the organisation.

Photos of the meeting are online, waiting to be integrated in the Utopia website.

And then, all of a sudden, out of nowhere it came: First snow and frost.

Traffic-jams (84 consecutive kilometers on the A1 today), canceled trains, failing electricity… The standard problems in the Netherlands when the temperature suddenly drops and snow falls over the country. Some photos I took.
