Letzte Woche spielte Deutschland auf Zypern. Nach 90 Minuten stand es 1:1 - zum ersten Mal seit der WM hatten wir nicht gewonnen und natürlich war das ein gefundenes Fressen für Presse, Funk und Fernsehen. Da konnte man doch endlich mal diese überbezahlten Idioten abkanzeln, die einen Haufen Kohle dafür bekommen, gegen den Ball zu treten und dann doch nur einen Punkt bei einem Niemandsgegner wie Zypern zustande bekommen. Eine Freundin von uns hat sogar alle 10 Minuten den Live-Ticker gecheckt, ob wir auch ja noch zurück liegen.
Dieses Ereignis hat mir mal wieder zu Denken gegeben. Im letzten Sommer waren wir noch alle stolz auf unser Team - der Fußball war gut und die Euphorie wurde nicht einmal durch die Niederlage im Halbfinale gebremst. Mit Eintreten der kalten Jahreszeit scheint sich nun aber auch wieder des Deutschen Gemüt zu kühlen.
Und was finden wir nun, tief in den Wurzeln unserer politisch korrekten und historisch bereinigten Leitkultur? Wir sehen, dass es da Leute gibt, denen es besser geht als uns - Fussballer, die wenig leisten und trotzdem unglaublich viel mehr Geld, Ruhm und Status erlangen als wir das je in unserem Leben erreichen werden. Für viele ist das offenbar ein Grund, wieder alles schlecht zu machen. Willkommen zurück in der Deutschen Neidkultur.
Hat sich einer der Neider eigentlich schon mal überlegt, warum diese Jungs so reich sind? Ganz einfach: weil es Leute gibt, die bereit sind, für Fussball zu bezahlen. Fans zahlen, weil sie Fußball lieben. Firmen zahlen, weil sie beim Fußball Werbung machen und die zahlenden Fans dann hinterher in den extra länger geöffneten Supermarkt rennen, um all die tollen Produkte zu erwerben. Dieses Spiel ist ein relevanter Teil unserer Marktwirtschaft.
Sportler sind ein wichtiger Teil dieses Spiels - warum sollen sie also nicht auch finanziell daran teilhaben? Können wir uns nicht einfach an ihnen erfreuen und ihr Können bewundern?

Exokernel snow
It's been a while since I posted some stuff on this blog. I really didn't know what to talk about at the moment. Don't want to go into details about football - Dynamo is a shame these days and I can only hope that this winter is not going to be as frustrating as last year's. There's also not much to talk about work - I am currently participating in porting our Device Driver Environment to support Linux 2.6 drivers. This is quite interesting for me, but there is not yet much to talk about.
The first rainy flakes of snow are cumulating on the rooftop window above me and I realize that although nights are getting longer, days becoming colder and the winds getting stronger, there are still nearly two months left until Christmas. (Best wishes to my friends Lars, Rene and Dina currently being in "icy" Russia... *wave*).
Winter term has started and we are doing some teaching again. Besides the normal exercise stuff and some advanced lectures on microkernel design, we are once again trying to start a Paper Reading Group. Neal, one of our students, is kind of interested in scientific papers from the old days. He proposed reading a lot of papers from the 1960's and 1970's. Today was the first meeting and as I'm always keen to gain more experience in giving talks, I volunteered for one of the first presentations. My talk was based upon two papers on Exokernels by Frans Kashoek, Dawson Engler and others:
The Exokernel does not do any resource management apart from tracking who is in possession of a resource (allocation, revocation, sharing). Security policies are implemented in the applications with only minimal support being necessary from the exokernel.
On top of the low-level hardware abstractions, exokernels implement higher-level operating system services in a library. These so-called libOSes are linked to each application and let application performance be at least as performant as traditional operating systems. The guys even implemented some custom-tailored applications that exploit the low-level exokernel layer in ways that enable very high performance.
I think I learned some interesting ideas, even though I don't agree with all the statements from these papers. Moreover, my conclusion is, that I need to read more scientific papers. Just sitting around all day, waiting for ideas to become rich, will not suit me well. Next is a paper about network packet filtering dating back to 1986...
