Keep it alive so that we can slowly migrate. Because migrating takes a lot of time. > > Cheers, > The SCG Team

You only need a plain web server to serve static files, that's what the mirror is doing.

Re: [Pharo-users] "Modern" mathematics with Morphic

by phil＠highoctane.be

Hi, I did that in school as well (and happen to have a bunch of super old math books over that from the sixties - from my mother in law, she was a maths teacher, as is my wife (there is a stream there)). Anyway, I did a pharo Morphic little app with drag and drop in areas where one drags and drops numbers and signs from one area to another, so doing that kind of thing is pretty doable. My app runs on the iPad with the StackVM. Drag and drop works perfectly well on it.

"Modern" mathematics with Morphic

by Alain Busser

Hi, when I was a child the times were to what was called "modern mathematics". It was quite strange, and we children had to draw Venn diagrams around pentagons (amongst other polygons) or the like. Now modern mathematics have become quite ancient (much like me) and everybody forgot about these "patatoids" (that's how we used to call them in french). Yet nowadays with tablets, exercises can be designed where, instead of drawing a Venn diagram *around* pentagons, the pupil could *move* the pentagons *inside* their Venn diagram (for a linguistic example, imagine moving the letters here: http://en.wikipedia.org/wiki/File:Venn_diagram_gr_la_ru.svg) These exercises where the pupil is to categorize objects or concepts, would be useful also in biology or grammar, if only... Well, ahem, I found out how to devise such exercises in JavaScript with jQuery UI (just declare any element as "draggable", then the sets as "droppable"). But I found out that it seems easy to drop a Morph (element) to another one (set), then make some set theory with "serious games". After all, that's what is shown in "Pharo by example" (drag and drop, and devise one's own method as to what can be dropped or not). Hence my question: Am I the first "genius" to think about this (doubtful) or (more probably) who did already this kind of exercises about set theory? Maybe in Etoys? Maybe not in mathematics but linguistics or other? A short bibliography on the subject: *http://www.cut-the-knot.org/LewisCarroll/tridiagram.shtml (was actually sold in wood with checkers pieces and an instruction book) * http://www.college-de-france.fr/site/stanislas-dehaene/course-2013-01-29-09… the baby learns to speak: There is classification to grasp vocabulary) * http://www.college-de-france.fr/site/stanislas-dehaene/course-2013-02-12-09… following: The baby uses bayesian inference to solve these kind of problems). If I understand well, the minimum age to play to these games is, after Dehaene, 6 months (!) Alain

Re: [Pharo-users] the future of squeaksource

by Paul DeBruicker

I think it would be helpful to have those public open source licensed projects that are not yet loaded on ss3 or smalltalk hub copied there for posterity. Maybe make a squeaksource archive account on each platform that does the copying.

Yes, I think this is the way to goâ¦ there are better things to do than to keep it alive with the limited resources we have. And if the file system is available, all scripts loading things from there will continue to work. Marcus
