Re: [Pharo-users] Using VirtualGPU
Hi Serge, I made some experiments with GPU computing with JavaScript. I understood that the computings are made forever inside the GPU, so you just throw data and programs once and you let the GPU compute for you. Yet the problem is to read the data once they are computed. With webGL it seems impossible, with webCL it is possible and not easy. Hence the choice of openCL I guess. I relate here how I could compute the powers of a Markov matrix here: http://revue.sesamath.net/spip.php?article651 (especially click on "webGL sans three.js"). I also made some experiments here: http://irem.univ-reunion.fr/spip.php?article797 (but they use three.js if I remember well) Happy readings, and, yes, I feel interersted in these subjects Alain On Tue, May 12, 2015 at 7:48 PM, Serge Stinckwich < serge.stinckw...@gmail.com> wrote: > Dear all, > > just to let you know, Cheikhou (in CC) is starting a student > internship in my lab. > He will work on Epidemiology Modelling with KENDRICK: > http://ummisco.github.io/kendrick/ > the platform that we are developing in order to analyse and visualise > diseases models behaviours. > > We would like first to implement a GPU version of the Gillespie > Stochastic Simulation Algorithm (GSSA): > http://en.wikipedia.org/wiki/Gillespie_algorithm and after that also > implement SPH simulations: > https://en.wikipedia.org/wiki/Smoothed-particle_hydrodynamics > > We are looking at the code of OpenCL and VirtualGPU done by Ronnie. > What we have understand until now : > - OpenCL package : low-level stuff to be able to interface OpenCL > kernels with Pharo > - VirtualGPU: high-level API on top of OpenCL in order to ease the > task of people who wants to use OpenCL.

Re: [Pharo-users] New random generator
the method from l'Ecuyer is already used in the texas instruments graphic calculators. But they don't seem to have patented it (I don't know how to check that). Anyway I agree to have more RNGs which can be useful for statistics simulations or kryptography. And I would like to know how one can play with the bacteria ;-) Alain PS did anyone receive the mail that I sent yesterday about syllogisms?

[Pharo-users] Logic in Pharo ?
Hello, I am currently working on mechanical means to solve Aristotle's syllogisms. My project is here: https://github.com/AlainBusser/LogicGame (programmed in CoffeeScript for a webApp). When I will present it (in a little more than two months) I plan to solve the same syllogisms with a software tool which must be free, of course. I am thinking about a lightweighted Prolog. Does this exist on Pharo? Or anything which would be similar (computing in a boolean algebra, something like alt-ergo etc)... and, if it runs on Raspbian it will be even better ;-) Alain
[Pharo-users] a successful success story
It is in French so I try to translate some parts. My goal was to teach as fast as possible the binomial distribution (number of successes when independently repeating a Bernoulli experiment) to students who, either have never seen an algorithm, or have seen some algorithmics in math lessons and don't like it at all. Both categories loved what I did with them. I precise that almost all of them are allergic to english language. The assignment was "throwing 10 dices, what is the probability of having at least 2 times "6" around the 10 results?" The whole job is related here: http://irem.univ-reunion.fr/IMG/pdf/binomiale.pdf (but I did only pages 1-5 in one hour) The first step was to show how one can simulate the throwing of 10 dices. I can do it without having to make a variable vary (explicitely at least), thanks to Seymour Papert: 10 timesRepeat: [ Transcript show: (6 atRandom)]. Then I spoke about the usefulness of the Bag object when there are statistics: Adding the 10 results (small integers) inside a Bag makes it an object where one can see and count the 6es: | urn | urn := #( ) asBag. 10 timesRepeat: [ urn add: (6 atRandom)]. Transcript show: urn. (Why "urn"? This is the word used by Bernoulli, he was thinking about balls concealed inside a vase for which the latin word was "urna"; the balls where called "billets" by Condorcet, so that they could instead be pieces of paper; whatever they were, a vase was use to conceal them) Then there remains only one difficulty: How can I automatize the counting of the 6es inside the bag? There is the most frightening challenge: Use a block with students who have never seen Pharo before. Very good surprise: They didn't seem to find this that difficult, I just had to say that 1. The pipe symbol means "such that" like in my lessons 2. The first time I use the letter "x" I have to tell Pharo that it is yet no variable to evaluate, hence the need to precede it with a colon. With that in mind, counting the 6es is the same as counting the x-es such x equals 6: | urn | urn := #( ) asBag. 10 timesRepeat: [ urn add: (6 atRandom)]. Transcript show: (urn count: [ :x | x=6]). Afterwards it remained only to repeat the whole experiment and, instead of showing the number of 6es, adding it to another bag called "stats", then displaying this bag. The end was made with a tool which exists only in mathsOntologie: The displaying of a bar chart in a translucent Morph, so that the most rapid of the students could compare several bar charts by superposition and guess the shape of the distribution. Once again, they all loved it, either because they found Pharo a better tool than whatever they knew before (and disliked), or because they knew nothing similar before (one exception: A girl who never learned algorithmics but just happens to love playing with a computer, here she is: http://reunion.la1ere.fr/2014/06/04/miss-reunion-muriel-roger-candidate-ndeg-9-158293.html ). I insist on the fact that they never saw anything like Smalltalk before, and did not seem to "rtfm": Is it because Smalltalk is a natural language or because MathsOntologie mimics the french language, I lack elements of comparison to answer to this. But I insist also to say that these students seem to dislike probability theory too. Finally, some stats about these stats: I can rapidly find the bugs when the text appears in red, and most of the time a point was missing at the end of a line, or a right bracket was missing or misplaced. Sometimes they add a space inside a word like asBag which becomes "as Bag". Alain Busser IREM La Réunion
Re: [Pharo-users] how do you use scripts?
For me, a script is an example for MathsOntologie, which is what I want to run when copied in the Workspace then Alt-D-ed. I distribute them with MathsOntologie and they are not versioned. I have ont script per file, all the scripts are grouped in an "exeamples" folder on disk, but I can not always open them because of utf-8 characters which are not correctly imported. Every file has a name recalling the script. I don't use "example" objects because I never thought about it (so, thanks for the idea). But if I knew how to incorporate MathsOntologie inside DrGeo I would use Hilaire's way of storing the examples of course...

Re: [Pharo-users] [Ann] Phratch 4.0
They are *really* lazy, to the point that nothing can make them work (at all, for example they never do their homework). But as they never work, they are often punished and as their teacher I have to give them some extra work during the punishments so I will give them this kind of "punishment". Besides, when one of them understands that it is the only way to have a software in reunionese creole maybe it will give them some energy, we can still dream...

Re: [Pharo-users] Scratch in Flash or Phratch?

Re: [Pharo-users] The fourth R
Strangely, I am preparing a Python session for pupils who are supposed ti know almost nothing about programming; and I finally came up with the turtle module! I realized that *COBOL has been invented so that people who work in banks and do not know how to program, can program *Basic was supposed to be usable by beginners (hence the "b" letter); which imho is false *LOGO has been invented so that such silly creatures as robots could program; and of course children could program in LOGO (and even, as I read, tech programmation at the age of 4) *Smalltalk has been created to cope with the mice and windows, but thinking about programmation for children (hence, Etoys and Scratch) *In France there was a thing called "LSE" which was supposed to help writing the program in a language neighboring French language. No one remembers that, but there were other experiments like "execalgo" or "algobox" (not mentionning MathsOntologie ;-)) Seeing that, I realize that a programming tool especially made for children is not really a new idea, but Python is cool for that. In France too Python is heavily used, especially for students. What surprises me is that the English government choose Python for *children* instead of, say, Scratch. I would not use xMaxima to teach fractions just because xMaxima is able to compute integrals!

Then the browser had helped you, as you would have found that the "-" is a method for subtraction only. But it takes more time to look inside this browser... The reward is that you find gold nuggets here and there; for example, when I saw that there were a "asRomanLitteral" for the integers, I was astonished and pleased at the same time.

Re: [Pharo-users] Number is not accepted by UI
That's where the Inspector comes in: To debug, it is good to insert a self width inspect so that the inspector opens up and reveals what exactly the width is. OK, it is a number; then open the browser and look at the number's methods; or in the finder, try 2 . -2 in the examples...

You're right but it should not have a fixed length because I want to remove numbers from it. I guess an SortedCollection is the best way to retrieve the next prime number.

Re: [Pharo-users] A question about sets
About the use of sets I found another idea: Eratosthene's sieve. Basically you create a set containing all integers from 2 to, say, 200. Then, beginning with 2, you choose remove all multiples of the number you choose from the set. Then you go to the next number in the set and so on... The difficulty is to choose the right collection, as a set is not ordered and it is not easy to loop on the prime divisors... I made it on this article (near the middle): http://irem.univ-reunion.fr/spip.php?article742 Of course you can have the set of primes directly under Pharo with isPrime as we did here: http://www.epi.asso.fr/revue/articles/a1211b.htm (I had forgotten this) Alain On Thu, Jun 26, 2014 at 8:21 PM, Hilaire Fernandes < hilaire.fernan...@gmail.com> wrote: > Great! > Now I wonder how it could be used within Dr. Geo. > > Thanks > > Hilaire > > Le 25/06/2014 18:33, Alain Busser a écrit : > > About the birthday problem, I already pulished something that I had > > exeperimented in the classroom, but it is in French: > > http://irem.univ-reunion.fr/spip.php?article618 (clic on "problème des > > anniversaires" tab).

Yes, and if there are no solution, you get an empty set instead of an error message. I find it more coherent, and simpler to use.

Re: [Pharo-users] Question on style
As solving an equation is basically giving the set of its solutions, I prefer to use a set to solve the equation.Instead of the OrederedCollection of course. It simplifies the algorithm if the discriminant is 0, because adding two times the same root yields a set with only one element, not the same element counted twice. The algorithm (much like the one with ordered collection) goes like this: *create an empty set with Set new. *compute the discriminant. *if it is positive, add to the set the "two" roots. *you're done!

First of all, you could simplify your code with dotProduct, writing dot2 := p1 dotProduct: p2.

Re: [Pharo-users] Writing a GUI - Where to start?
Hi, as I have a similar need, I guess what you are aiming at is a tutorial for absolute beginners in Spec, so the question is more "where could we find such a tutorial?".

Re: [Pharo-users] SmalltalkWorld chartFrameworks.
I didn't *have to* download file by file, I just wanted to try everything that I could. Doing the Gofer trick still does not allow me to launch a PPBrowser. If I try with a fresh image, it works OK, that may prove that Petit works well on Pharo 2.0, but on my own image it don't work, so there may well be some competition between Athens and Petit (or MathsOntologie and Petit?) Next step: I removed, by hand, any package which name begins with "petit", then to crash Pharo I just have to do Gofer new smalltalkhubUser: 'Moose' project: 'PetitParser'; package: 'ConfigurationOfPetitParser'; load. and that's all! With a fresh image, I will have to load Athens and MathsOntologie again, won't I? Plus the changes that I already made to MathsOntologie...

Re: [Pharo-users] SmalltalkWorld chartFrameworks.
Yes, I done it as you wrote with Gofer, then I used Monticello to download petit (file by file), then I done the Gofer trick again, and I still have the same problem: A nil as "bottom" which blocks a subtraction... If I am the only one to encounter the problem, it probably comes from somewhere else but where?

Re: [Pharo-users] SmalltalkWorld chartFrameworks.
I dropped the image on Pharo and I still have this illegal subtraction message. I don't build anything, I just downloaded Pharo 2.0 "one click" and added MathsOntologie, DrGeo and PetitParser. Plus the (almost) daily updates. The debugger says that GLMSystemWindow's "addMorph: fullFrame" method has a subtraction where WindowBorderWidth (which equals 4) is subtracted to bottom; and bottom is nil, so it don't understand the "-" message (I doubt a nil object understands anything). So I guess the question is "why is bottom nil?" I see that at the beginning there is bottom := frame bottomOffset. Whereas frame is a LayoutFrame ( (0@0) + (4@4)px corner: (1@1) + (-4@nil)px ) so I imagine the nil comes from this point, no?

in the "world" menu, "tools" then "petitparser"; the browser method is "openWith: aRender" which fails to render anything in GLMMorphicRenderer...

Re: [Pharo-users] SmalltalkWorld chartFrameworks.
OK, I used Monticello with the Moose address, and downloaded petitsmalltalk and PetitParser, as well as configuration files. I made (Smalltalk at: #ConfigurationOfPetitParser) perform: #loadDefault. once again, and clicked on the petit entry in the tools menu ... and Pharo crashed!

Re: [Pharo-users] SmalltalkWorld chartFrameworks.
I made Gofer new renggli: 'petit'; package: 'ConfigurationOfPetitParser'; load. (Smalltalk at: #ConfigurationOfPetitParser) perform: #loadDefault. The tool is actually loaded but when I try to launch it from the system menu I get a receiver of "-" is nil Same message if in the workspace I type PPBrowser new open, but not if I try PPBrowser new inspect (there, I have an inspector open on the PPBrowser) I'll switch to smalltalkhub now Alain On Fri, May 17, 2013 at 10:44 AM, stephane ducasse wrote: > ALL*** the moose people are using PetitParser and it loads in 20. > so where you took the code from? > > The official repositories are on SmalltalkHub/Moose > > Stef > > On May 16, 2013, at 8:27 PM, Alain Busser wrote: > > Hi, > > I have a similar problem with PetitParser (loads well under Pharo 1.4, not > as well under Pharo 2.0) > > Alain > > > On Thu, May 16, 2013 at 8:56 PM, Camille Teruel > wrote: > >> >> On 16 mai 2013, at 17:59, stephane ducasse wrote: >> >> yes normally the moose people. >> This is strange because eyesee is in Moose and we load it daily in 2.0. >> >> >> Maybe the smalltalk hub repo is more up to date? >> >> >> Stef >> >> Thanks for your answer Camille! >> >> I tried it. >> It loads well on 1.4 but in 2.0 shows warining about a non satisfied >> blockclosure class. >> >> Then when I run the test there is a faliure with the anouncements, which >> also accured when I tried the examples. >> >> Is someone maintaining this? >> >> Thanks again, >> Juan >> >> >> On Thu, May 16, 2013 at 11:27 AM, Camille Teruel < >> camille.ter...@gmail.com> wrote: >> >>> Hi Juan, >>> >>> You can have a look to eyeSee: >>> >>> Gofer it >>> squeaksource: 'EyeSee'; >>> package: 'ConfigurationOfEyeSee'; >>> load. >>> (Smalltalk at: #ConfigurationOfEyeSee) loadDefault >>> >>> >>> On 16 mai 2013, at 16:03, Juan Ignacio Vaccarezza wrote: >>> >>> Hi all, >>> >>> Does anybody know a chart framework?

Re: [Pharo-users] SmalltalkWorld chartFrameworks.
Hi, I have a similar problem with PetitParser (loads well under Pharo 1.4, not as well under Pharo 2.0) Alain On Thu, May 16, 2013 at 8:56 PM, Camille Teruel wrote: > > On 16 mai 2013, at 17:59, stephane ducasse wrote: > > yes normally the moose people. > This is strange because eyesee is in Moose and we load it daily in 2.0. > > > Maybe the smalltalk hub repo is more up to date? > > > Stef > > Thanks for your answer Camille! > > I tried it. > It loads well on 1.4 but in 2.0 shows warining about a non satisfied > blockclosure class. > > Then when I run the test there is a faliure with the anouncements, which > also accured when I tried the examples. > > Is someone maintaining this? > > Thanks again, > Juan > > > On Thu, May 16, 2013 at 11:27 AM, Camille Teruel > wrote: > >> Hi Juan, >> >> You can have a look to eyeSee: >> >> Gofer it >> squeaksource: 'EyeSee'; >> package: 'ConfigurationOfEyeSee'; >> load. >> (Smalltalk at: #ConfigurationOfEyeSee) loadDefault >> >> >> On 16 mai 2013, at 16:03, Juan Ignacio Vaccarezza wrote: >> >> Hi all, >> >> Does anybody know a chart framework?

[Pharo-users] a 'doesNotUnderstand' message that I do not understand...
Hi all, Exploring the system browser (Pharo 2.0), I see that there exists a class called TextEditorDialogWindow; as this name sounds interesting to me, I want to test one, and I see that there is only one method in the category 'create': this method is called newTextEditorMorph. So, I send the message newTextEditorMorph to the class TextEditorDialogWindow, daring a: TextEditorDialogWindow newTextEditorMorph At the 'Do It', I get this error message: 'TextEditorDialogWindow class(Object)doesNotUnderstand: #newTextEditorMorph' That's what I don't understand: If the class has a method called this way, why does it not understand the corresponding message? What did I miss? Alain
