So, jetzt ist es also passiert. SPIEGEL ONLINE berichtet, dass die UNESCO Dresden den Weltkulturerbetitel aberkannt hat, wegen der Waldschlösschenbrücke. Ist vielleicht besser so, denn jetzt kehrt hoffentlich Ruhe ein. Man konnte die ewigen Diskussionen ja nicht mehr hören.
Man kann die Brücke ja gut oder schlecht finden. Was ich aber nicht nachvollziehen kann ist Folgendes. Das Dresdner Elbtal war ja auf der Liste des Weltkulturerbes, nicht etwa des Weltnaturerbes; das gibt es auch. Kultur also im Sinne von vom Menschen Erschaffenes, nicht nur Musik und Malerei oder sowas. Das, was die UNESCO als schützenswert auserkoren hatte, waren also nicht die schönen grünen Elbwiesen, sondern das Elbtal von Pillnitz bis Übigau, mitsamt Parks, Gebäuden, Brücken, Werften und Schiffen, so die Begründung für die Aufnahme. Die Begründung erwähnt, dass verschiedene Errungenschaften vom 16. bis zum 20. Jahrhundert im Dresdner Elbtal versammelt sind. Warum muss aber die Kultur im 21. Jahrhundert aufhören? Die Menschheit entwickelt sich schließlich weiter, und die Zeichen, die diese Entwicklung setzt, können und sollen auch in eine außerordentliche Kulturlandschaft einfließen. Im Dresdner Elbtal wurden schon diverse Brücken gebaut, die teilweise wie das "Blaue Wunder" selbst Sehenswürdigkeiten sind und sogar ausdrücklich von der UNESCO erwähnt sind. Die neue Waldschlösschenbrücke ist vielleicht nicht die schönste Brücke der Welt, aber sie ist ein Ausdruck der Kultur der Gegenwart.
Der andere Aspekt, der diese Geschichte zur Farce machte, ist das Lamentieren der hohen Politik und nationalen Prominenz. Fakt ist: Die Dresdner Bürger haben in einer Volksabstimmung für die Brücke gestimmt. Und selbst nachdem die UNESCO angefangen hatte, ernsthaft damit zu drohen, den Titel abzuerkennen, haben in mehreren Umfragen deutliche Mehrheiten gemeint, dass sie trotzdem wieder für eine Brücke stimmen würden. Warum das so ist, sei dahingestellt. Vielleicht ist den Dresdnern der schnelle Weg zu Arbeit oder zum Flughafen wichtiger. Oder man hat erkannt, dass das kulturell wertvolle Blaue Wunder eigentlich ein Verkehrsnadelöhr ist. Aber die Bürger haben entschieden und das gilt es zu akzeptieren. Die Bürger können ja später auch mal dafür stimmen, die Brücke wieder abzureißen.

Praise to LXDE
I've been know to rant at times about crappy Linux desktop software. So here's a praise for a change: a praise to LXDE.
You know when the name of a piece of technology starts with "Simple" or "Lightweight", it's really not? SMTP, SNMP, LDAP? Well, LXDE proves that wrong.
I first heard about LXDE from Klaus Knopper's presentation at Chemnitzer Linux-Tage 2009, where he described why he chose LXDE as the new default desktop for his well-known Knoppix live CD/DVD/environment.
I have never really been interested in the debate of late about how short we can possibly get the boot time of a Linux machine/desktop, since I've been using suspend-to-disk for years everywhere. I only reboot for kernel upgrades, and possibly when the wakeup gets botched, which happens about once a month, I guess. But that's a different matter. What I was interested in was a lightweight desktop environment to run inside a VirtualBox.
So LXDE. apt-get install lxde gives you the whole thing. Well, the only thing that's missing is a web browser, which you will have to select and install yourself. I had reported previously on the amusing quest to find a "lightweight" web browser.
Unlike some geek-enabled minimal desktop environments, LXDE doesn't surprise the average user with an unusual layout. You have a taskbar at the bottom (can be moved to the top, for those used to GNOME), with a menu button, buttons for file manager, terminal, browser, minimize all windows; on the right, there is a CPU meter, a clock, a screen lock and a logout button. At least on Debian, the terminal and browser buttons call x-terminal-emulator and x-www-browser, respectively, so whatever browser you choose to install, it will work. There is also an image viewer and a handful of minor tools and settings available through the menu. And you can start random commands with Alt+F2. But that's more or less it.
Another thing that is interesting about LXDE is that it makes "ps" useful again. Under KDE, a "ps x" on relatively idle desktop produces what feels like 50 processes. Under LXDE it shows 15, which includes the terminal, bash, and ps processes to produce the listing. And it looks like with a bit of effort that number could be reduced even further.
Even though it's quite small, LXDE supports freedesktop standards. It uses desktop files, dbus, openbox as window manager, and supports compiz if you want. You can easily run GNOME or KDE applications, and they will behave reasonably. Once you do, however, they will of course load their lot of libraries and daemons, and the lightweightness will be gone. So on a workstation desktop, where you might want to run a graphical mail program, a calendar application, network manager, update notifier, and so on, LXDE will probably not buy you much. But on netbooks and virtual boxes, where all you need is a browser and a shell, this is a great alternative that is usable by everyone, and one that is true to its lightweight attribute. So far.

SlideShare and Creative Commons
Today I uploaded all the presentations that I have held at tech conferences over the years to SlideShare. (At least those that were in a reasonable format. I was a user of DocBook Slides in the early days, which produces HTML, which you can't upload to SlideShare.) That was quite a trip through history for me; 6 years of traveling, meeting people, pondering ideas.
I have also gone through and licensed all presentations and this blog under a Creative Commons license. For various reasons I chose different variants of Creative Commons for different bits, but in the future I plan to mostly use the CC-BY variant, which is much like the BSD license in spirit.
