  1. Obesity on Scientists Say the Future Looks Bleak For Our Bones · · Score: 3, Funny

    Maybe the added weigh of obesity, will cause more force on our bones and compensate for the lack of it by moving less.

  2. Bootstrapping and time travel on Physicist Kip Thorne On the Physics of "Interstellar" · · Score: 3, Interesting

    Spoiler alert for the movie Interstellar

    It seems he did not get the main idea of the movie. The whole movie rests on the idea that it is possible to manipulate gravity in the past. The traversable wormhole was created by some humans in the far future and allowed the main character to communicate with the past, causing himself to join a space program, which would lead him to the place to communicate with the past, and by this save human kind from some disaster and in the far future allow to develop the technology to create the wormhole and a black hole with strange properties. So, it also involves a form of bootstrapping. Which makes even less sense, if indead traversable wormholes could be made at all.

  3. People are the problem on "Ambulance Drone" Prototype Unveiled In Holland · · Score: 4, Insightful

    Here in the Netherlands the problem is not in getting an AED on the site, but to find someone who can apply it. There are many people trained in using AED's and we here in the Netherlands possibly have the highest density of AED's, and although there is an elobrate system to call trained people to a person with a cardiac arrest, the problem is still in getting enough volunteers to join in. It is no use to have an AED within 200 meters from every house, if you don't have people who can apply them. AED's are not difficult to use, but in a case of emergencie, you need someone who can keep his/her head calm and follow the instructions.

  4. MRI did have some effect with my wife on Magnetic Stimulation Boosts Memory In Humans · · Score: 2

    In 2006 my wife reported that her memory improved after she had an MRI taken of her head when she was suffering from memory problems. A few months later, also based on lumbal puncture, she was diagnosed with early-onset Alzheimers disease. She reported that her thinking became much more clear. The effect only lasted for half a day. When I told her neurologists, she laughed it away.

  5. Another ring: Method Engineering on Peer Review Ring Broken - 60 Articles Retracted · · Score: 1

    There are whole fields within Computer Science, one being "Method Engineering", that basically are one big ring. For your information, "Method Engineering" is about methods for developing software.

    I guess that the language where you could shuffle your cards is DYNAMO.

  7. 1978: IBM Fortran to Cyber Fortran on One-a-Day-Compiles: Good Enough For Government Work In 1983 · · Score: 1
    The summer of 1978, I spend some time to convert a large Fortran program in the IBM dialect to Fortran on a Cyber mainframe. The program consisted of about 1500 punch cards. At first I would load the whole deck every time. After some time, I discovered it was possible to store the program on disk and edit them by-line using a program called Update. This still requires typing punch cards. Everytime, I checked the cards many times to make sure, I did not make any mistakes. And then it was waiting before the monitors showing he input, the execution, and the output queue, If it was out of the output queue, you still had to wait before the output was dropped in one of the labled boxes, which could take another ten minutes. In those times memory usages was billed in the Kbytes per second. I did it for nothing. Just the fun to work on a real mainframe was enough. Afterwards, I was rewarded with the book `Finite Mathematics' by Seymour Lipschutz.

    The person giving me the assignment also wrote programs in some kind of simulation language where the lines could be in any order. Sometimes he would shuffle the cards while standing in line for the cards to be read, just to make fun of the other waiting.

  8. Programming is hard, is because computers are slow on Toward Better Programming · · Score: 0

    One of the main reasons why programming is hard, is because computers are slow. This may sound very counter intuitive, but the fact that computers look like they are fast because they make use of many smart tricks, most of which we are no longer aware off. It is important to realize that computers all rely on the memory piramid, where in the top of the memory there is a little very fast memory and at the bottom there is a vast amouth of slow memory (often distributed in a system called The Internet). The range in speed and size is more than 9 powers of 10. A lot of effort is spend in copy data between the kinds of memory inside this memory piramid. And to be able to implement systems that appear fast, we have to deal with all the small tricks that are used in the system to make it look fast. Knuth has said that very often premature optimization is the root of all problems. The real fact is that almost every act of programming (in an imperative language) is an act of optimization, namely finding an implementation of a function with given constraints. Take for example the simple fact that whenever we deal with an integer in a program, it is an integer within a limited range. But an integer could be arbitrary large. So as soon as you declare an integer in your program, you are performing an act of optimization, because you decide that in your case the range of values within your function are limited to a certain power of 2. (Except if your language has an implementation for BigInt, but even these always have a limit.)

  10. Google for: "elektrische fiets" on Invention Makes Citibikes Electric · · Score: 1

    Here in the Netherlands, where we have as many bikes as inhabitants, electrical supported bikes, have become very common. Google for "elektrische fiets" for some images of these. The battery packs are either build into the frame or put under the luggage carrier at the back. We installed under the luggage carrier, it often is a battery pack that can be taken out. The electrical motors are build into the wheel and there is a small dial on the steering wheel with which you can control the extra support needed. To still have to padel yourself, but the electronics will add some extra power to it. Often these bike have a display showing you the battery status. From a first glance these bikes look like normal bikes. Both old en young people are using these kinds of bikes.

  11. Re:Cameras and phones on CES 2014: 3-D Scanners are a Logical Next Step After 3-D Printers · · Score: 1

    It seems that all the good solutions are commercial and that most of the freeware solutions are crappy, meaning that either the UI is difficult or that the output has many artifacts or is incomplete. Still looking for a good solution with which you can create a good 3D-model using a set of pictures, like PTGui, which allows you to tweak the results of the various steps and correcting mistakes made by the automatic steps.

  12. Why? Natural resources. on How Quickly Will the Latest Arms Race Accelerate? · · Score: 3, Insightful

    Why this arms race? There can only be one reason: access to natural resources. Some natural resources (such as cheap fossile fuels) are on the decline, and China wants to keeps ite growing population happy, otherwise those in power might lose their position. The other superpowers also want to keep their positions. Cheap natural resources (ranging from water to fossile fuels to rare earth metals) are an essential fact for a healthy economy.

  13. His bio: Solution for n-particle problem on Kazakh Professor Claims Solution of Another Millennium Prize Problem · · Score: 3, Interesting

    In his bio it is claimed that he found explicit formulas for n-particle motion in the space (in the framework of Einstein’s relativity theory). If that would be true, I guess it would have be known in the rest of the world as well, if he had.

  14. Why not in English? on Kazakh Professor Claims Solution of Another Millennium Prize Problem · · Score: 4, Insightful

    If it is such an important article, why did he not find someone to translate it to English? He did get some related papers published in English. It seems that those are about approximations. Interesting non the less.

  15. Results are from simulation on MIT Uses Machine Learning Algorithm To Make TCP Twice As Fast · · Score: 1

    If you read the page, you will see that the results are from a simulation and not based on experiments in a real network. And the given performance only works under certain stable conditions. Some remarks seem to imply that if you are moving around (like with a mobile device) the results no longer apply. Still, I believe that machine learning techniques could out perform human coded algorithms, but probably not as much as the 'theoretical' results presented in this research/paper.

  16. 80 missing in Canada on Boeing 777 Crashes At San Francisco Airport · · Score: 1

  17. Maybe both of you are mistaken on Ask Slashdot: What To Do When Another Dev Steals Your Work and Adds Their Name? · · Score: 1

    Usually when software is developed for a payment, the copyrights lie with the organisation paying the money, not with the developer, except when specified otherwise, which rarely happens. Many employment contracts even state that all software developed is owned by the company you work for, including software you develop in your private time. The reason for this being that you are not supposed to work (paid or unpaid) without written permission from your employer, and that there is often a thin line between what you do for your work and what not. In most cases employers don't mind you develop software in your private time and claim copyright, but there might be cases in which they might want to claim copyright, when for example, you develop some algorithm using knowledge you learned while working at your company that in someway could be profitable for your company.

  18. Real reason: not enough resources on Dutch Bill Seeks To Give Law Enforcement Hacking Powers · · Score: 3, Insightful

    It has been argued that one of the real reasons behind this bill is the lack of resources with the police to follow-up all the now already available means of tracking down offenders. Appearantly, it is much cheaper to use hacking tools than to do some old style research and detective work. Or at least that is the impression given by those marketing these hacking tools.

  20. LOFAR - interferometric array on IBM Designing Superman Servers For World's Largest Telescope · · Score: 2

    ASTRON is the organisation that is also running LOFAR, which is basically a smaller version of SKA in a different frequency range. It is an interferometric array which requires a central system to process all the signals into one result. LOFAR is using a lot of dedicated hardware and a IBM Blue Gene/L supercomputer for this purpose. Because all the signals are digitized at the receivers, this result is a very large stream of data, which are processed (but not stored) by a pipe-line of processors, each combining more and more signals, into one final image.

  21. Bike production CO2 footprint on State Rep. Says Biking Is Not Earth Friendly Because Breathing Produces CO2 · · Score: 1

    It would not surprise me, if the production of the bike causes more CO2 to be released than all the extra CO2 that is produced while using the bike. Also, one would also need to look at the life style effects of people who do bike and who don't to determine if cyclist do produce more CO2.

  23. Christian Freeling on AI Systems Designing Games · · Score: 2

    I guess that you should read How I invented games and why not by Christian Freeling to understand that designing games with AI is nonsense, because the best games always come from combining mechanisms and not by changing the properties of some of the pieces at random and trying to find an interesting combination. Chess like games, with pieces with different properties, are not the class of most interesting board games.

    I remember that in the sixties you could buy boxes with just pieces from one colour. I would not consider thoses sets. I also remember buying a container with Duplo blocks for my daughter about 15 years ago. Although Duplo is technically not Lego, it is produced by the same company and compatible with Lego. Although they are rare, these sets with only simple block, still are being sold. As for example Lego set 5509.
