Re: [Pharo-users] searching for protocols

by Ben Coman

Also interested in this. A few times I would have like to have done something like... 'someProtocol' allMethods and got a list like ClassA>>method1 ClassB>>method1 ClassB>>method2 but I haven't needed it enough to bother working it out. Actually its the sort of thing that would fit well as a feature added to Finder. cheers -ben On Fri, Mar 20, 2015 at 5:16 AM, Peter UhnÃ¡k <i.uhnak(a)gmail.com> wrote: > Hi, > > is it possible to find which class uses particular protocol? > > Typically I am not sure how to name a protocol so I would like to check > out other classes. > For example the system offers me to name protocol as "enum primitives" but > I don't know who uses it and for what exactly. > > Thanks, > Peter >

Re: [Pharo-users] New random generator

by Alain Busser

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?

searching for protocols

by Peter UhnÃ¡k

Hi, is it possible to find which class uses particular protocol? Typically I am not sure how to name a protocol so I would like to check out other classes. For example the system offers me to name protocol as "enum primitives" but I don't know who uses it and for what exactly. Thanks, Peter

But I wanted to know what you think. Great ! Maybe better to integrate them in Sci-talk with the existing Random Number Generator (RNG). We have already 5 RNGs. I'm working on refactoring the RNG and distributions in Sci-Talk, because there is some redundancy until now: https://groups.google.com/forum/#!topic/scismalltalk/zXEyeGvTmJk Regards, -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

New random generator

by stepharo

Hi guys Konstantin who is a biologist developed for a "bacteria" eating monster simulation system, two new random number generators. I think that this is great because we need more random generators :) - Combined Random Number Generator is based on the algorithm described by PIERRE L'ECUYER in "Efficient and Portable Combined Random Number Generators" [Communications of the ACM, June 19, Volume 31, Number 6, pp. 742-749, references p.774]. - ExpInvConGen is an explicit inversive congruential generator, constructed according to "Good random number generators are (not so) easy to find" by P. Hellekalek (1998) and extended euclidean algorithm. I plan to package them and publish them in SciTalk with their own configuration. But I wanted to know what you think. Stef
