Comment Different kind of APIs (Score 1) 173

APIs have different complexities. There are simple APIs that shouldn't be eligible for copyright because they don't meet the minimum standards of originality (from the viewpoint of an experienced programmer). They only serve as a technical construct needed for interoperability of modules. But Java is not one of them. It has a huge library with many interacting classes and class member functions. Typically, in object-oriented languages, the interface code is a large part of the total amount of code. I think it needs to be decided on a case-by-case basis whether an API can get copyright. The really stupid decision by Google was to use a proprietary language like Java for Android and not an open-source language.

Comment Acer Travelmate B117M (Score 1) 187

http://ixsoft.de/ is a Linux shop in Germany that offers netbooks with all kinds of Linux distros preinstalled, so I assume the netbooks they use are compatible. One model they offer is the Acer Travelmate B117M, which Acer targeted at the educational sector. It is robust, has a non-glare display and a replacable battery.

Comment Old hat? (Score 3) 80

Solar thermal collectors that can boil water have existed for decades. You don't need concentration for that, simply use a black absorber plate with pipes under a glass plate and put a vacuum between the absorber and the glass. Selective absorbers or glasses will improve the efficiency.

There are two problems with it: The generated steam will have a low temperature not much above boiling water. Most industrial applications need process steam of a much higher temperature (although there are some exceptions).

There are also problems with the two-phase flow of the steam-water mixture in the pipes, which is generally unstable and difficult to control. Technically it is much easier to concentrate sunlight, use an oil with a high boiling point as the carrier liquid and use it to generate the steam in a seperate unit.

The CSU is no longer opposition. Since the election in 2014, Munich is governed by a coalition of the Social Democrats (SPD) and the conservatives (CSU). Linux was introduced when a coalition of the SPD and the Green Party held the government with Christian Ude (SPD) as mayor. Ude fully supported the migration. The new mayor Dieter Reiter (SPD) is more critical and did not object in an interview to being characterized as a "Microsoft fan". He was involved in the negotiations about Microsoft moving its HQ into the city. The new deputy mayor Schmid (CSU) also critized Linux shortly after the election.

Comment What about butter? (Score 1) 851

Trans-fat does not only occur in margarine or other hydrogenated vegetable oils, but also in butter, which contains up to 4% trans-fat (of the total fat content). While this is less than in most (but not all) margarines, it is not insignificant.

Doxygen doesn't cost anything and is very useful for exploring an unknown C++ code. You should configure it to include private functions and the source code browser. Then you can navigate through the source/reference with a simple web browser, and it will allow you to dive deeper into the details when necessary and easily backtrack after it.

It might be true that the ovens need to be run with different parameters or even built differently, but taking the wet garden and kitchen waste out of the mix is a good thing. Obviously some energy goes into drying the wet components before they can burn. Also, if the burning plant is used for electricity generation (and many plants in Europe are hybrid, i.e. they produce both electricity and heat), then burning at a hotter temperature produces more electricity out of the same amount of trash (see Carnot's law of thermodynamics).

Comment No reputation (Score 3) 247

Crowdfunding works only together with reputation. If you simply give money to any unknown person who starts a project, then it's your own fault if they run away with it. Reputation means that creators seeking funding need to do their first few projects for free until there are enough fans who believe that the creator will really deliver and who like the quality of the previous products.

Nuclear Energy Now More Expensive Than Solar 635

js_sebastian writes "According to an article on the New York Times, a historical cross-over has occurred because of the declining costs of solar vs. the increasing costs of nuclear energy: solar, hardly the cheapest of renewable technologies, is now cheaper than nuclear, at around 16 cents per kilowatt hour. Furthermore, the NY Times reports that financial markets will not finance the construction of nuclear power plants unless the risk of default (which is historically as high as 50 percent for the nuclear industry) is externalized to someone else through federal loan guarantees or ratepayer funding. The bottom line seems to be that nuclear is simply not competitive, and the push from the US government to subsidize it seems to be forcing the wrong choice on the market."

Doubled Yield For Bio-Fuel From Waste 97

hankwang writes "Dutch chemical company DSM announced a new process for production of ethanol from agricultural waste. Most bio-fuel ethanol now is produced from food crops such as corn and sugar cane. Ethanol produced from cellulose would use waste products such as wood chips, citrus peel, and straw. The new process is claimed to increase the yield by a factor of two compared to existing processes, thanks to new enzymes and special yeast strains."
