  1. Re:This cow can be milked. on Germany's New Internet License Fee · · Score: 1

    Yes, Grundversorgung only means "basic supply", thanks for correcting it. Regarding the megaphones: You are right. Applying the same ratio here means a tax on ears. If you are able to listen to news with two ears, you are eligible for a discount on the second ear though ;)

  2. This cow can be milked. on Germany's New Internet License Fee · · Score: 2, Informative

    The term used for justification is Grundversorgung (basic supply with news) really pisses me of. The first thought is, why should I pay for something, regardless wether I'm using it or not. Exspecially cable-modem users will be ridiculed (who will open the phone-line for 1 Euro/hour to listen to internet-radio?).
    Basic supply with news only is required because of possible catastrophic event. But this fee should be paid by every citizen equally, because the emergency plans include sending around police cars with megaphones. Why is there no GEZ-fee on using megaphones??? Ok, better don't remind them. Where I'm getting my day-to-day news from on the other hand, should be my decision.
    An internet connection is not necessarily a channel for "Grundversorgung" (what about washing machines with internet connection?). You have to pay already only if it is possible for you to access these channels (which are not only news like tagesschau.de but also come with a lot of other crap no sane person would pay for and which is not accessibly by internet anyway). The GEZ is extending its mandate way beyond basic supply with news and expects to get paid for it by mandatory fees. No thanks!

  3. Open-source software of the MiCRoN project on Swarms of Microrobots Over Europe? · · Score: 1
    I've both participated in the MINIMAN- and the MiCRoN-project.

    Micro-manipulation in our days is either done with an expensive customized systems (chip-manufacturement) or manually (cell-manipulation). The aim of micro-robotic projects is to bring automation to the micro-scale.

    At the end of the MiCRoN project at least 3 robots where build and fully assembled. For example there is a list of robots, which were build in the MINIMAN-project already. Only 2 of them were used for the final demonstration. Many prototypes had to be build and discarded, before the design was completed.

    It is true, that PCB-soldering is fully automated, but this is done with highly customized systems. On the macro-scale even the industry is interested in making assembly lines more flexible. It is also true, that cell-manipulation has become a common task in research and industry. But it is rarely done in an automated way. If a project requires injecting 10000 cells with a fluid, most probably the project will be dropped.

    When researchers are operating a scanning electron microscope, they regularly have to break the vacuum to do a very simple manipulation. A microrobot in the vacuum chamber can save a lot of time here.

    The MiCRoN public report has not yet been released. However the MINIMAN-report is here and we have published a lot of pictures and demonstration-videos on our MMVLWiki.

    Note, that most of the control- and computer-vision-software is running under Linux. The real-time computer-vision library called Mimas and the computer-vision software of the MiCRoN project is available for free under the terms of the GNU license.

  5. Messing up the time systems on U.S. Scientists Call for a Time Change · · Score: 3, Informative
    Ever since the beginning of measurement of time the main goal was to keep time in sync with the rotation of the earth and the date with the orbiting around the sun as accurately as possible. Otherwise a date wouldn't tell the season and the time of day wouldn't tell about the sun's position.

    Programmers of astronomical software already have trouble enough:

    1. The year -1 is followed by the year 1
    2. 4.10.1582 is followed by 15.10.1582, because only then the length of a year was measured with sufficient accuracy. The new system of leap years will only need a fix of one day in another thousand years.
    3. Last century Ephemeridical Time (ET) was introduced to serve as a constant measure of time (in contrast to the Universal Time (UT)). The commonly used time is UTC, which is running with the same "speed" as ET and being corrected every once in a while, when (UTC-UT) becomes greater than 0.9 seconds. Astronomical software has to know UT as well as the difference ET-UT: The positions of other planets have to be computed with ET and the rotational angle of the earth with UT.
    ET-UT is more than 60 seconds at the moment already. Replacing UT/UTC with ET-60 s will not really make things easier and it will deprieve the old system of its benefits! If someone needs a ET-clock for doing satellite navigation, he shouldn't force everyone else to do so as well. If the U.S. scientists keep pushing, I'll switch to a russian time-server in the future.

  7. kphone & vic (Linux software) on Open Source Alternative for Skype · · Score: 1
    I think, that it is better to have a VoIP-softphone.

    In contrast to skype (and openwengo?) kphone f.e. uses standard codecs (G711u, GSM, iLBC for audio and H261, H263 for video) for communication. I'm using the provider voiptalk.org (website is currently down) to get connections to/from landline-phones (using GSM-codec) as well.

    Here is a document on how to install it.

    But maybe the Openwengo developers are planning to do this anyway (I couldn't see this from the project's website though).

    I agree. According to The Decline and Fall of Global Warming Siberia is subject to a local greenhouse-effect caused by a rise of the air's humidity. Furthermore it is said:

    Nothing is free from risk of danger!

    A good measure (at least on earth) is the ratio "death per billion passenger-kilometers". These are the numbers for Europe (1999):

    • Airplane: 0.8
    • Train: 0.4
    • Car: 8

    I don't have the numbers for the Space Shuttle, but I think, that even counting the full distance travelled (relative to earth), that the Space Shuttle would look quite bad.

    Out of university or out of software-development? ;-)

    Most people don't apply the discipline of personal software process to themselves.

    From what I see I gather, that the success of a software-project (wether at university or in business) strongly depends on the amount of competition. As soon as your project is kind of in-house, individualism and code-ownership are the only remaining forces and you're in deep trouble.

    There's an interesting paper on how to do SVD-correspondence for (corner-)features.
    One can determine optical flow from this and it would be useful for sensing the motion of a flying robot f.e.

    Another interesting paper is about using correlation to estimate speed in an incremental way.

    You can see, that the problem gets feasible as soon as you restrict the domain sufficiently. Restricting the domain is crucial in computer-vision. Otherwise you'll end up searching for the holy grail of computer-vision ;-)

    A state-of-the-art solution would be using a UIML-renderer, which should be available for any platform and programming language one day.

    UIML is a subset of the XML-language for implementing platform- and programming-language-independent user-interfaces.

    Maybe you should have a look around, whether there is a good UIML-renderer for Java.

    If your research is into this topic, you may even want to develop a UIML-renderer for Java yourself! I'm sure many people would be interested in an open-source project with this aim.

    I am using Qt (with C++) and qt-designer myself, which is using a proprietary XML-format for rendering user-interfaces (ui-files).

  19. Not Scary! on Of Ants and Robots · · Score: 1

    I absolutely agree. I don't have the reference, but it's a known fact, that the message, how many new workers and soldiers have to be breed (the ratio), is being transmitted by hormones/pheromones while cross-feeding. That means, that on the second day, the composition of the population has adapted itself a bit to the new requirements. There's no need to call on a mysterious collective mind for explaining this! Give it an ant's lifetime (about a month?) and the time for coping with a destroyed nest will be back to the initial value.
