you can find the current list of packages in script loader latest version.

Re: [Pharo-project] Looking for a package to do some statistics in Pharo

by Douglas McPherson

Indeed, you should check out DHBNumerical. I'm using it for Kalman filter development/simulation, and have previously done Galois field simulation using Bessett's DHBPolynomial. These are many included probability distributions and statistical queries built in, so quite likely has what you need. No underscores needed :) Doug On Mar 2, 2012, at 10:12 , StÃ©phane Ducasse wrote: > Hi guys > > I would like to know if there is a package doing some statistics in Pharo. > I should check the work of didier besset but I want to know if there is more. > > It would be good to have such kind of package. > > > Stef >

And you know this. Release early, release often is also valid for pharo. And is not done, you just tell everyone else to do it like this ;) :) But I'm exclusively using 1.4a to code :). Seriously we want to make sure that in the future we can release anytime. Now it means that we need help to fix red tests and other bugs. Stef

Re: [Pharo-project] Looking for a package to do some statistics in Pharo

by Schwab,Wilhelm K

Stef, I think our banned troll is back :( Beyond that, nothing as important as statistics is off-topic here. I tend to use R because it does "everything," though its language is almost purely syntax over substance - hardly the OO bliss that its creators seem to believe it is. Some things (e.g. linear regression, medians, quintiles in general) have filtered into my reach with Pharo. Attached is some work so far on GSL, targeted at 1.3 and up. You *might* find what you need in #gsl_stats_* methods, but no promises yet. I regenerated the whole mess to use underscores, making it *far* easier to match code with the GSL documentation. Ditto on the structures, which are a big mess right now. I am trying to isolate "bad" things in packages marked "old" to ease ridding myself of Camel case where it hurts (interfacing). Camel case is nice in wrappers, and I am using it there. This will take time to finish, but I hope to release a set of wrappers that are important to me (YMMV) and the generated methods and structs to follow along in wrapping things important to others. It is big library. Challenges over time have included the long absence of callbacks, and various levels of underscore support that forced me to Camel case when I should not have done so, but had no choice "back when," and now problems passing void* and bumps in generating struct field accessors in recent FFIs. Failing those things, this would have been done a while ago, but that's a lot of "ifs."

[Pharo-project] ConfigurationOfRefactoringBrowser fails

by Benjamin

In the method postLoadRBSpelling "We want to initialize and download the dictionary file so that tests can be run without internet." Smalltalk at: #RBInternalSpellChecker ifPresent: [:cl | cl new ]. the new invocation leads to Error: Improper store into indexable object. And due to that, Nautilus builds fail. I have to go to bed now, but if someone could have a look, I will appreciate :) Thanks in advance, Ben

Hi Janko-- 1. Name minimal virtual machine Level intermediate Possible mentor Craig Latta Possible second mentor Eliot Miranda (I'm volunteering him :) Description Create a minimal Squeak virtual machine, to accompany the minimal object memory provided by the Spoon project (http://netjam.org/spoon) Technical Details Benefits to the Student The student will learn the organization of the Squeak virtual machine. Benefits to the Community The community will benefit from an improved virtual machine organization, making it easier to learn and easier for newcomers to contribute. 2. Name object memory modularization Level intermediate Possible mentor Craig Latta Possible second mentor (volunteers sought) Description Modularize the Squeak object memory into Naiad modules (see http://netjam.org/spoon) Technical Details Organize the classes and methods of Squeak into composable modules using Naiad, Spoon's history system. Develop tools to aid in this process. Benefits to the Student The student will learn how to create deployable Squeak applications, by helping to invent the process. Benefits to the Community The community will benefit from improved techniques for collaboration and deployment. thanks! -C -- Craig Latta www.netjam.org/resume +31 6 2757 7177 + 1 415 287 3547
