I found this book: http://books.google.com/books?id=QPX7_MP8w5UC&lpg=PP1&ots=bIsemiaRUC&dq=did… Then from that found this code: http://sourceforge.net/projects/dhbnumerics/ Then checked with the maintainers of that code and got permission to post it up on squeaksource here: http://www.squeaksource.com/DHBNumerical.html It seems to work just fine for what I needed. Thanks again Paul

Are there Chi-Square, Power, Normal, Binomial, Uniform, Student's-T etc distributions ?

by Paul DeBruicker

Hi - Is there a standard library access and make calculations from the distributions mentioned in the subject of this email? I'm interested in random draws from those distributions. I haven't found anything looking in the image or on squeaksource. Thanks Paul

[GSoC] Problems, Students bio and projects without mentor

by Mariano Martinez Peck

Hi everybody. I hope everybody is fine. As you may have noticed, the ESUG GSoC has been quite busy the last weeks. Students started to register in the website, discuss with mentors, etc... A little problem that we saw few times: when you register (as a student or mentor) you should receive a confirmation email. I don't know why but some people reported this mail was filtered in the spam folder. So, if you are mentor or student and didn't receive a confirmation email, please check you spam folder. Students, when you edit your profile there is a tab called "Biography". Please, take the time to complete that. There are multiple students per project and that may help the mentor to choose the student. Another problem is that we have two projects without mentors. 1. Native windows for Squeak and Pharo http://gsoc2010.esug.org/projects/native-windows 2. OpenSSL Smalltalk wrapper http://gsoc2010.esug.org/projects/openssl Fortunately no student yet expressed interest on any of them. There is a deadline in Monday to remove them if there won't be any mentor found. That's all for the moment. Mariano ESUG GSoC admin esug.gsoc.adm2010(a)gmail.com http://gsoc2010.esug.org/

using weak collections

by Yoandy RodrÃguez MartÃnez

Hello again: I need to create an object's registry that keeps certain objects in a dictionary and a second registry that keeps only objects currently in the first registry so i thought it was a good idea to user IdentityDictionary and WeakIdentityKeyDictionary so when the any object in the first registry is removed then the second registry remove's it too. Problem is that when i try to test my code, the second assertion fails. Is there anything wrong with my test or weak collections are not suppose to work like that? ColonyTest>>testWeakRefs |registry anotherRegistry object | registry:= Registry uniqueInstance. "this keeps weak references" anotherRegistry := Colony new. object:= ColonyMember new. registry register: anotherRegistry. anotherRegistry addMember: object. registry register: object. "object is into the second registry" self assert:[ anotherRegistry contains: object]. "if we unregister this reference then the registry should lose it too" registry unregister: object. self deny:[ anotherRegistry contains: object]
