  • This weekend, programmers from all over Europe will be gearing up to compete in the 5'th Catalysts Coding Coding Contest (CCC'11). This year, the theme is Astronautics.
  • The competition is also open to online participants.
  • Individuals or teams of up to three people will be given a series of challenging problems that must be solved as quickly as possible.
  • ...2 more annotations...
  • As a contestant, you must conceive of a proper solution and produce the correct output in order to advance to the next level. How you get there is completely up to you. You may use any computational means at your disposal.
  • Online contestants will not be eligible for prizes – they compete for glory alone.

    One more nice citizen scientist example as I try to find for space since some time. Any good ideas this mit inspire you to?

    IF THERE IS A MUSHROOM IDENTIFICATION APP I BUY AN IPHONE IMMEDIATELY!!!

    why don't you programme one and get rich?

    Would love to but this requires *TIME* :-( Automatic image-based mushroom recognition... perhaps could do as a FP7 study... it may save lives actually!

    anything happening on this since 3 years?

    yes it seems like. most of it seems however directed toward understanding this effect, and not toward applications. But i'm still convinced that we could find many very interesting applications !!! a few references from ADS: 1 2011PhRvA..83f3807B 1.000 06/2011 A E X R C U Brida, G.; Chekhova, M. V.; Fornaro, G.

    Could be stimulating to watch the episodes during a ACT meeting as a base for brain storming. Especially interesting for YGTs or RFs with no space experience. The episodes will be repeated starting form 17 feb. Will be available in german and french

    Any viral licence is a bad license...

    I'm pretty confident I'm about to open a can of worms, but mind explaining why? :)

    I am less worried about the can of worms ... actually eager to open it ... so why????

    Well, the topic GPL vs other open-source licenses (e.g., BSD, MIT, etc.) is old as the internet and it has provided material for long and glorious flame wars. The executive summary is that the GPL license (the one used by Linux) is a license which imposes some restrictions on the way you are allowed to (re)use the code. Specifically, if you re-use or modify GPL code and re-distribute it, you are required to make it available again under the GPL license. It is called "viral" because once you use a bit of GPL code, you are required to make the whole application GPL - so in this sense GPL code replicates like a virus. On the other side of the spectrum, there are the so-called BSD-like licenses which have more relaxed requirements. Usually, the only obligation they impose is to acknowledge somewhere (e.g., in a README file) that you have used some BSD code and who wrote it (this is called "attribution clause"), but they do not require to re-distribute the whole application under the same license. GPL critics usually claim that the license is not really "free" because it does not allow you to do whatever you want with the code without restrictions. GPL proponents claim that the requirements imposed by the GPL are necessary to safeguard the freedom of the code, in order to avoid being able to re-use GPL code without giving anything back to the community (which the BSD license allow: early versions of Microsoft Windows, for instance, had the networking code basically copy-pasted from BSD-licensed versions of Unix). In my opinion (and this point is often brought up in the debates) the division pro/against GPL mirrors somehow the division between anti/pro anarchism. Anarchists claim that the only way to be really free is the absence of laws, while non-anarchist maintain that the only practical way to be free is to have laws (which by definition limit certain freedoms). So you can see how the topic can quickly become inflammatory :) GPL at the current time is used by aro

    whoa, the comment got cut off. Anyway, I was just saying that at the present time the GPL license is used by around 65% of open source projects, including the Linux kernel, KDE, Samba, GCC, all the GNU utils, etc. The topic is much deeper than this brief summary, so if you are interested in it, Leopold, we can discuss it at length in another place.

    Thanks for the record long comment - am sure that this is longest ever made to an ACT diigo post! On the topic, I would rather lean for the GPL license (which I also advocated for the Marek viewer programme we put on source forge btw), mainly because I don't trust that open source is by nature delivering a better product and thus will prevail but I still would like to succeed, which I am not sure it would if there were mainly BSD like licenses around. ... but clearly, this is an outsider talking :-)
  • LeopoldS on 01 Nov 09
     
    btw: did not know the anarchist penchant of Marek :-)
  • Ma Ru on 01 Nov 09
     
    Well, not going into the discussion about GPL/BSD, the viral license in this particular case in my view simply undermines the "clean and clear" motivations of the initiative authors - why should *they* be credited for using something they have no rights for? And I don't like viral licences because they prevent using things released under this licence to all those people who want to release their stuff under a different licence, thus limiting the usefulness of the stuff released on that licence :) BSD is not a perfect license too, it also had major flaws And I'm not an anarchist, lol
