Capitalist environmentalism

While I could be considered concerned about the environment, I am by no means a tree-hugging hippie. For instance, I firmly believe that alternative energy sources should be economically feasible before being implemented for large-scale energy production.
For instance: how much does it cost to build and operate a windmill? How long will it last, and what is the value (price) of the energy that it generates? I know that ten years back, this sum yielded a negative result: the windmill itself was more expensive than the energy it generates. Using windmills back then was not a wise decision. I must admit I don't know about the current situation. With advances in engineering, it is quite possible that windmills are now feasible.
I think that, as 'traditional' energy sources become more expensive because of increasing consumption and, hence, shortages, the alternative sources will become viable. Subsidies are unneeded and, indeed, unwanted.

With respect to electronics, the tipping point has been reached. With increasing demand for stuff like gold and copper, the prices have gone up. This has made it viable to recycle discarded electronics -- not to spare the environment (though that is certainly a welcome side-effect), but because the recycling plant produces as much raw gold as a small goldmine. Recycling is, literally, a goldmine.

I think this is incredibly cool.

Step 1 completed

I finished converting the 'CDIndex'-application to a set of MySQL tables plus PHP pages. Now any OS with a LAMP stack can publish the information -- which is to say: all of them.
Since it's now a web-application (using the term 'application' very loosely...), I added stuff like being able to click through to other information. For instance, you can get a list of disc numbers that the episodes of a particular series are stored on (the main usage of CDIndex). But now the disc numbers are also links to a page that lists everything on that page. From there you can link on to the episode list of all the series that have an episode on that disc, etcetera.
Programming the combobox was a bit of a hassle, but it's done now.

The next step is to port 'FitOnCD', the application that calculates the 'optimal' filling of a disc, to a Python script.
