Making Cultural simulations on Kedama
by Offray Vladimir Luna Cárdenas 19 Oct '06

19 Oct '06

Hi all, First, thanks for the SqueakFest2006. It was really awesome to be here, to know all that squeakers, to listen them, and to speak with them (a little). If love is the key to make visitors become residents, thanks for such warm act of love in such nice city :) I'm now getting back to my academical activities and I'm wondering, after the speak of Yoshiki, if Kedama can be used to make cultural simulations also (may be you remember that I'm interested in the "Cultural Thing" of cognition also). I'm thinking to start with a specific simulations showed in the book The Complexity of Cooperation from Robert Axelrod. It's about culture dissemination. Axelrod model different cultures as part of a grid (that where the idea of using Kedama come from). Every culture is a cell in that grid and every culture has a number of traits (for example 5) wich can have different values (lets say 10). What Axelrod says is that when two agents (cultures) are similar one to each other (it' means they share the same value in the same trait) they have more possibilities to interact and become even more similar. The algorithm is something like this: Repeat these two steps as much as wanted: 1) Select randomly a culture in the grid and select randomly a neighbor of that culture (in such grid neighbors can be on north, south, west or est). 2) This two cultures interact with a probability equal to their cultural similarity (that is, the number of similar values in the same trait of these two cultures). That interaction consist in selecting a trait where this two cultures are different and change the value of that trait for the value of the neighbor. The process define a set of culture regions. You can find the source code of the implementation of Axelrod's algorithm in: http://www.cscs.umich.edu/Software/CC/CC7/CULTURE.P.html (<- Pascal version) http://www.cscs.umich.edu/Software/CC/CC7/FullCulture.p.html (<- Full Pascal version) http://www.cscs.umich.edu/Software/CC/CC7/CULTURE.BAS.html (<- Visual Basic version) ¿Do you think is feasible to implement the same model in Kedama? If yes, ¿Where is the best way to start implementing it? Thanks a lot, Offray Ps: I will be probably on Wikimania next weekend (I have the scholarship acceptance and now I'm trying to get the proper permissions in the University). So may be we can see there :). ___________________________________ AVISO LEGAL: El presente correo electronico no representa la opinion o el consentimiento oficial de la PONTIFICIA UNIVERSIDAD JAVERIANA.

Re: [Squeakland] squeakland plugin for unix
by Brad Fuller 22 Sep '06

22 Sep '06

Hi All, New to this list. I submitted the following email to squeak-dev. Anyone here answer these? ======================= a few questions on the squeakland browser plugin for unix, if someone in-the-know can answer: Is the squeakland image special? (different from the regular ol' squeak images?) Is the vm different too? Or is the only difference the npspeak.so file and the symbolic link it creates (e.g. create symbolic link `/usr/lib/firefox-1.5/plugins/npsqueak.so' to `/usr/lib/squeak/3.7-7/npsqueak.so') I'm afraid the squeakland vm will overwrite my current vm. Is that needless worrying? Can I run them independently (that is without changing directories and creating links so they don't interfere in the "default" installation process) ======================= BTW: I receive this error: 'Error loading http://www.squeakland.org/uploads/WeaselEssay1.015/resource.10.form when loading the project on this page: http://www.squeakland.org/whatis/a_essays.html

squeakfest conclusions
by José L. Redrejo Rodríguez 02 Aug '06

Hi, all I've checked the Squeakfest'06 schedule page and donwloaded some of the materials that are available there. Unfortunately, the sound of the S. Papert speech recording is pretty bad, specially for those who don't have english as our native language, the noise make some parts really hard to be understood. Anyway, it's wonderful to be able to see it for all of us who haven't could attend this year. I would like to know more about how the event has gone, some of the topics of the schedule that look very promising, as SimBuilder, don't have any information at all, to know the state of the art for this project. But, what for me would be more useful is to know the general impression of the attendants to the current state of the Squeak use in particular, and of computers at schools in general. Squeak is more or less involved in a good bunch of projects as Tweak, Sophie, Croquet, Scratch, OLPC, etc, but the feeling I have from the distance is that all that cloud of projects don't seem to be followed by the educators, they just look like laboratory experiments, not being applied to the classroom except for some testing purposes. The main Squeak community seems to be quite stationary and almost no new projects (in terms of .pr files and also, in term of the application use) have arrived for the last year. Maybe it's just an impression as the squeakland site is not updated too often, maybe it's the real world. Some of you know that in Spain, in our Extremadura region, some crazy people are fighting trying to use the computers to build a new way of thinking and a new way of teaching, but the main stream in the educative community is really strong, and what I see here, and in the rest of the world is that most of the budget is going to pay applications or platforms that just translate the text books to the computers, as if that were enough to justify the use of computers in the classroom. When the teachers have their curricula contents in the computer as in the book, they feel safe. That's a stupid way of thinking for me as the text book is cheaper and easier to use, but people feel comfortable that way. So, ending with this too long mail, my main questions are: - what's the feeling people have brought after attending squeakfest? - Are there new development or projects being made in Squeak, or around its projects? - Any other related thing you would like to tell to all who felt sad not being in Chicago listening and learning.. Best Regards. José L.

Thanks so much for your notes. I have could get some of them from the video, but I have learnt some others from your blog. Anyway, the video lasts more than an hour, so I suppose there are many more ideas left..

I'm sorry to hear that Seymour Papert's address didn't come out so well on video and audio. I took some very sketchy notes of his address and posted them on my blog, Shiftin' Paradigm Blues; the URL is in my sig below. It was truly an inspiring address; I hope you can get some sense of it from my notes.

[ANN] SuperSwiki2 Server Bootable ISO image
by Masashi UMEZAWA 17 Jul '06

17 Jul '06

Hi, I have created a special USB bootable version of SuperSwiki2 Server. Features: o SuperSwiki2 starts automatically after booting. o Other SuperSwiki2 clients recognize the SuperSwiki2 server automatically. o The uploaded project data is stored in the USB memory automatically. Just booting up from a USB memory, you can start eToys project server. Project data is saved in the same USB memory, so it is very handy to carry with from classrooms to classrooms. More info: http://swikis.ddo.jp/SuperSwiki2/24 Enjoy! P.S. I do not attend SqueakFest. But my friend, Abe-san, will attend the fest and have a sample USB memory of this bootable SuperSwiki2 Server. So, if you have some interest, please ask him. --- [:masashi | ^umezawa]

Brilliant, thanks Kim! My two-year-old and I whiled away some time yesterday with a lovely rocket launcher Etoy from NASA. Launching rockets is not something we can do safely in the physical world until he is a little older :) For what it is worth, it might be helpful to the clueless, like me, to bring all the Etoys, both community ones and VPRI ones, under a single Etoys link on the home page. That link right now goes to the squeak fest 2004 contributions. David
