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).

Richard Stallman's Solution To 'Too Big To Fail' 649

lcam writes "A Richard Stallman opinion piece appears at Reuters addressing the 'Too big to fail' view that has recently caused large corporations to be bailed out by taxpayer dollars. His solution is elegant: 'We tax a company’s gross income, with a tax rate that increases as the company gets bigger. Companies would be able to reduce their tax rates by splitting themselves up.' However, it could use some refining. For example, his measure would create a required minimum 'Return on Investment' scale that corporations need to follow to be viable, and these types of metrics are very industry specific. Another issue is that many large corporations stay in business because they don't take unnecessary risk. Companies like Intel, Lockheed, Walmart are very large and have a very low chance of failure, yet Stallman would have them split up as a result of the excessive risks that banks and insurance companies were seen to have taken. It also has the potential to cause problems with the global market; some multinationals may find it better to simply 'move out' to a country that doesn't compromise their business models. How can this idea be made better?"

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.

Coming To a War Near You: Nuclear Powered Drones 202

An anonymous reader writes "American scientists and engineers are researching a new generation of UAV's that would be nuclear-powered. Why do this? They would have the capacity to stay over a target area for months and only be limited by the ordinance they could drop on a potential foe. They would be similar to a nuclear attack submarine but not limited to the amount of food on-board. The article notes: 'The blueprints for the new drones, which have been developed by Sandia National Laboratories – the U.S. government's principal nuclear research and development agency – and defense contractor Northrop Grumman, were designed to increase flying time "from days to months" while making more power available for operating equipment, according to a project summary published by Sandia,' the paper reported."

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."
