Scientists Discover That Exercise Changes Your DNA

prefec2 Re:What does this mean...? (22 comments)

No. The genes are already present. They only get activated when you exercise. Therefore, you should leave your basement and walk or run around your block for 45 minutes a day or alternatively walk or cycle to the pizza or Chinese place instead of delivery any you have the same improvement. However, if you do not desire a healthy and long life, and a more optimistic view on the world then please don't do it.

RFID-Blocking Blazer and Jeans Could Stop Wireless Identity Theft

prefec2 Perfect! I combine it with my tinfoil hat (107 comments)

Well great idea. First, I chip me, my clothes, my belongings, my accessories. And then I use a tinfoil jacket and trousers to block them all. Great idea. On a second thought. Such clothes are the perfect addition to my tinfoil hat. However, for complete protection I would recommend tinfoil underwear, socks, and - because this is slashdot - condoms to be absolutely safe.

Ask Slashdot: How Should a Liberal Arts Major Get Into STEM?

prefec2 Start a STEM topic (275 comments)

The solution is simple. Study a STEM topic at a real university. If you live in the US you also need proper funding. In many EU countries you could just enroll. And starting studying with 25 is not too late at all. You could still finish MSc in 5 years.

The Case For Flipping Your Monitor From Landscape to Portrait

prefec2 What the fuck? (566 comments)

Honestly, why does that gets posted on slashdot? Turning monitors sideways is an flipping old feature. And people where using it now for years. Even my professor has one of his screens sideways. The old Xerox machine with the first graphical UI had such screen orientation. For documents it makes much more sense to have it that way. In programming most tools fill up the screen on the left and right. Therefore, for that purpose portrait mode is not an option as long as the tools are that way. But for writing, viewing and editing text portrait is perfect. And I do not need an article about that fact, promoting it like it is some super genius idea.

EU May Not Unify Its Data Protection Rules After All

prefec2 In other news (55 comments)

The German government was in favor of net neutrality. If Merkel's reelection might be in jeopardy due to her position on net neutrality she will change her position. So this is not the end of it.

Furthermore, if a fragmented EU market hinders US monopolies to extend their services to the EU then this is not necessarily a problem for the citizens here in the EU.

Which Programming Language Pays the Best? Probably Python

prefec2 Embedded Systems (277 comments)

In Germany embedded systems make up 22 billion eur while information systems are only 8 billion. In embedded sys. you need c and that ISO language bundle.

In both cases entry is 30 or 40 k eur. And real good figures normally involve an architectural or management role where only little programming is left.

Security Experts Believe the Internet of Things Will Be Used To Kill Someone

prefec2 Bathtubs are dangerous too (165 comments)

Humans have killed people with all sort of technology. They are quite creative about the topic. They drowned people in their own bathtub or toilet. They burned down houses and even used pest invested dead people as weapon. Of course they will use any new technology also to do it. However, using model planes or helicopters to kill people is not new. Furthermore, they are not Internet of Things or IoT is any remote controlled vehicle implying the radio control is also some sort of Internet. In general IoT is a stupid term as is it Internet of Humans. Internet is just the combinations of networks to form a large one. When at all, it should be called Internet for Humans and Internet for Things.

LinkedIn Study: US Attracting Fewer Educated, Highly Skilled Migrants

prefec2 Re:map of worldâ(TM)s most racially tolerant (338 comments)

Interesting link. Thanks. However, the question here is the image of the US which I tried to describe. So it is not necessarily necessary that all hold. Anyway, the bureaucratic mayhem which is involved when trying to get to the US is real (and it has nothing to do with the US citizens at all).

Two Google Engineers Say Renewables Can't Cure Climate Change

prefec2 Rubbish (652 comments)

For starters all renewable energy scenarios involve a reduction in energy us by 80% which is easily achievable when you isolate your homes and make devices more efficient.

The EU thinks this change is possible. And for example Denmark want to be totally free of carbon emissions by 2050.

The problem of these two guys is that they want renewable energy at the same price as coal plants which are directly and indirectly subsidized in many ways. In addition you normally do not pay for the environmental impact of extracting the coal from the soil. There for coal is much cheaper.

And by the way we had in western Europe a decline in energy consumption over the last decades while still the economy was growing. There for, the assumption that growth implies more energy consumption is not generally valid. And furthermore, economic growth might not be a present indefinitely. So many assumptions of those two Google guys are wrong and therefore their conclusion is also wrong.

LinkedIn Study: US Attracting Fewer Educated, Highly Skilled Migrants

prefec2 Re: Unsurprising if you think about it (338 comments)

Here is a list of reasons why many Europeans won't come. You are not one of those socialist European countries with a public healthcare system. You have 12 times more people shot per year and per inhabitant then any EU country. There is a lot of racism in the US. Your immigration procedures and your fear of terrorism.
All in all your image sucks. You are no t the country of the free and brave. You are quite the opposite. There is also a lot if violence in your country. All causes not to come. And for EU citizens the lack of a welfare state shocks us even more than the high rate of gun possessions.

Multiple Manufacturers Push Hydrogen Fuel Cell Cars, But Can They Catch Tesla?

prefec2 Re:Bad idea (293 comments)

A fuel cell + hydrogen tank have a much higher energy density (even when measured in fuel cell output) as any battery in the next couple of years will have. Therefore, there could be a market. Especially, as with renewable energy sources the production of hydrogen could be triggered just then when there is an overproduction of electricity and store it.

But, true cars (electric or otherwise) are not the best solution for all our transportation problems. Therefore, we must move away from them where they are a sub optimal solution.

Alva Noe: Don't Worry About the Singularity, We Can't Even Copy an Amoeba

prefec2 Re: AI researcher here (455 comments)

AI are more or less reasoning machines which is not the same as intelligence. There is no awareness or understanding which are necessary to call it intelligence. Most likely your definition of intelligence and that of other scientists differ tremendously. To understand the professor you must obviously use the definition from his field and not yours.

Ask Slashdot: Best Practices For Starting and Running a Software Shop?

prefec2 Outsource (176 comments)

When you setup up accountancy and have a lawyer, you can create a development team. Depending on your domains, expertise, and scale you want to enlist people for domain analysis, requirements engineering, software design, programming, UI design, etc. As it is too expensive to hire so many people, it might be best to outsource that to freelancers. Therefore, you need an appointment with your lawyer to draft the necessary contracts.

Indian Brick-and-Mortar Retailers Snub Android One Phones

prefec2 Re:Indians screw Indians for a change (53 comments)

The Indians or Chinese did not screw the US tech. industry. The management in the US did. Nobody was forced to outsource to India or China. However, someone (and I am not pointing fingers ... well ok, I am) lowered import duties to establish a global market for products and services resulting in direct competition of First World (FW) workers with all their benefits with Third World (TW) workers without any benefits, resulting in more profits for the companies and either less benefits for FW workers or no jobs for FW workers.

If you want to change that policies then you have to vote in the US for erm. I don't know the commies or the Green party, as Democrats and Republicans both love globalization of markets. In the EU you might vote for the so called far left. Do not vote for social democrats as they also love globalization just like their conservative friends. And don't tax the rich.

Harvard Scientists Say It's Time To Start Thinking About Engineering the Climate

prefec2 Yeah, lets play Zauberlehrling! (367 comments)

We do not know in detail how the climate system works. True, we have some understanding and we know what happens when we release CO2, methane, CFCs to the atmosphere. However, our models are never good enough to predict the outcome of specific effects we introduce to fix the other problems. Normally such things only work in Star Trek and you can run away in your ship if you fail (however they never fail in the series).

But who cares? Lets play Zauberlehrling (engl. sorcerer's apprentice) http://en.wikipedia.org/wiki/T... (poem from J.W.v.Goethe) and f*** up the climate. They are from Harvard, therefore that is a really brilliant idea. Well, after reading the original article, they (he) is more into lets address this research topic. Therefore, we need funding. Hello? We need funding for this very important thing otherwise we are all doomed or must stop driven SUVs which means we are all doomed. Thanks.

Interviews: Ask Adora Svitak About Education and Women In STEM and Politics

prefec2 Women and STEM Topics (155 comments)

There have been a lot of talk and even initiatives to improve the number of women in the STEM field. While I myself participated in assessments for young women to encourage them to choose STEM topics, I am less and less convinced that these initiatives are working. The main problem is that we do not really know why women choose other topics. True they have been asked what they want and why they have chosen this instead of STEM. However, this does not give us the root cause which pushed them in that particular direction.
The lack of female "nerds" cannot be the root cause, as they tend to study pharmacy or accounting. Therefore, it must be something else and we should start resarching to uncover the truth. However, I doubt that this will ever been done, because getting to the bottom of things is much more pain then fooling around and starting ineffective programs.

Japanese Maglev Train Hits 500kph

prefec2 Re: 510kph is airliner speed? (419 comments)

This might have something to do with the fact that the two Hokkaido and Tokyo are on two different islands.

In addition you can fly in Germany from Hamburg to Berlin and Munich. But still most people use the train. For two reasons. Hamburg Berlin is 1.5 hours by train you cannot reach the plane in that time and definitely not fly. Munich req. 6 hours by train so a plane might be faster, but you can jump on a train every hour without planning for a specific hour. You cannot do that with a plane.

Japanese Maglev Train Hits 500kph

prefec2 Maglev is expensive (419 comments)

Germany developed similar technology, but was unable to sell it to the public for two reasons. First, it is expensive compared to normal tracks. This includes maintenance and construction. Second, it must run on a bridge like thing. A ground based solution is still 2 m above the ground.

The Chinese tried out that German solution. They built a small line but skipped the extension.

The French TGV can go 500 km/h but normally runs 300 or 350 km/h.

In Germany the next generation of trains will be even slower which makes perfect sense, as Germany is densly populated and there are many stops. So hhigh speed would not result in a big time savings

Open Access Petition

prefec2 prefec2 writes  |  more than 5 years ago

prefec2 (875483) writes "I know Slashdot is just a site, read mostly in the US and other English spoken countries. However, this might be still interesting for readers of Slashdot and may be some Germans read it too. In Germany it is possible to send and sign e-petitions to the parliament (Bundestag). And I want to point out that there is a petition on Open Access waiting to be signed from you guys. If more then 50 000 people sign it, the initiators can make a public appearance before the Committee of Petitions, which will give the topic more publicity. So please go and sign it. The e-petition site is available here: https://epetitionen.bundestag.de/index.php?action=petition;sa=details;petition=7922 [translated version of the petition] The German parliament (Deutscher Bundestag) may enact, that scientific publications, which where funded buy the public, shall be accessible to all citizens without any fees. Institutions, which manage public research fund autonomously, shall be requested by the Bundestag to release appropriate directives and provide the technical means to publish results for free (as in beer and as in speech). Rationale The public sector finances research and development with 12 billion Euros every year (according to the ministry of education and research). However, the results of this research are mostly published in journals which are available only for a fee. It is not appropriate that the text payers have to pay again for research results they financed. Research results are only available in a few libraries, because of the high costs and the multiplicity of journals and other publications. The access of research results funded by the public is therefore hindered and even made impossible for normal citizens. To exclude citizens from the sciences is not only destructive, it is also unnecessary. Other countries already implemented similar rules. The US American agency National Institutes of Health (NIH) requires, that all publications funded by NIH have to be made available to the public at a centralized location in 12 month. The basic structure of the scientific publication system is by such actions not changed."

Censorship Law passed Parliament in Germany

prefec2 prefec2 writes  |  more than 5 years ago

prefec2 writes "After a long debate in Germany, a bill for Internet censorship passed the Bundestag (federal parliament). The politicians say that they only use the new censorship infrastructure to hide child pornography form accidental access. However, it is easy for criminals to circumvent this blockade. For news sites, like Slashdot, the Times, or Wikileaks, the censorship technology is harmful. After the implementation of this new filter, the censorship can easily be expanded to other areas. Some politicians are already lobbying for blocking file-sharing sites, "killer game sites", and other security threats. More information can be found on heise http://www.heise.de/newsticker/Bundestag-verabschiedet-Gesetz-fuer-Web-Sperren--/meldung/140746 (german) and the law draft http://dip21.bundestag.de/dip21/btd/16/128/1612850.pdf (german).

We all grieve for our constitution, which has been ripped by our own parliament."
