Call about Numerical Methods in Pharo :)
by stepharo March 6, 2016

March 6, 2016

Hi guys I met Didier Besset and we had a great hacking session and discussions with Serge Stinckwich. Didier would like to help Pharo and the numerical part of it. ***Big thanks*** Didier. We would like to do several things: - Work on "Hows to" The numerical methods in Pharo is good but the gap between us and the math is too large :) so the idea is to have a series of "how to ..." - histomgram (simple, based on distribution) - Improve the SciPharo/NumPha (previously SciSmalltalk) library This morning we started to implement a ComponentPrincipalDecomposition by combining two of the objects available in SciPharo. Then we started to enhance the distributions to make sure that we can plug other distribution for having controlled random number. - Do a public call to know what is missing for you: this is this mail :) Didier would like to work on concrete cases. I love that attitude So tell us :) Hernan ?? Alex: ?? pvalue? better distribution? Vincent: covariance? CPA? Philippe: times series Serge R frames? Sami: Better random number and various distributions? - Organise a two day lectures with practices on concrete case in September with a recording session. Either at IRD Bondy or Lille. - Make sure that the Numerical Method book will get on lulu :) with a better cover and title :) Stef

Starting to add class comment and test on BlElements
by stepharo March 6, 2016

March 6, 2016

Hi blockers and alek in particular, the code is cool and I like that each method is commented. I'm starting to write a real class comment that we will be able to use in a documentation. But I cannot run the example so this is difficult to write tests. So Alek how do you know that you make progress? Where should I start? I thought BlElement was the starting point. Side note: Now I wonder if we want to have all the assert: May be yes and we should have an opal plugin to turn them off after. allChildrenDo: aBlock "Evaluate aBlock for all my children gathered recursively (excluding the receiver). aBlock must not be nil. aBlock must accept exactly one argument" self assert: aBlock isNotNil. self assert: aBlock argumentCount = 1. self childrenDo: [ :child | aBlock value: child. child allChildrenDo: aBlock ] Stef

[Bloc] about resizing
by stepharo March 6, 2016

March 6, 2016

Hi alex I would like rewrite exact: aNumber self resizing: (BlLayoutExactResizer new size: aNumber) as exact: aNumber self resizer: (BlLayoutExactResizer new size: aNumber) you have Object subclass: #BlLayoutAxisParams instanceVariableNames: 'resizing' classVariableNames: '' package: 'Bloc-Core-LayoutStrategy-Core' and the resizing method is in private protocol however it looks like it is used a lot outside. So should I change all the senders + protocol? Stef

I do not know in which world you live. You are probably not exposed to students and to technology stack, techno center, hackaton and other place were developers gather and hack. You probably use Smalltalk for your hobby and this is great. I'm selling Pharo to industry and programmers and the competition is real. I'm sad because you did not get anything that I'm said. Sorry but I will not continue this thread. Now you will not force us to market Pharo the way it should. If you are not happy, put money on the consortium and come to talk to us but you will be disappointed because the complete board is thinking the same. We are marketing our future. Now I will ask to be ban from this list such recurrent discussions. Why because we all lose time and you make me losing a lot of energy and frankly I would be you I would prefer that Stephane Ducasse, the Great Energizer is focusing on producing cool videos, new books or whatever instead of talking about this "pharo is smalltalk" shit. Yes you see I spent 14 hours to go to discuss with didier and we pushed the numerical method book (that I reviewed in the past several times), with serge we edited the new version of the book, we patiently collected all the libraries over the years, we are fighting with dependencies and more. So it gives the right to do what we want and if you are not happy, I'm sorry about it but this is like that! Stef

[Bloc] what is the purpose of OpenGL package?
by stepharo March 6, 2016

March 6, 2016

HI alex What is the purpose of OpenGL package? How does it relate to bloc? Because I thought that the point was not to have direct opengl dependencies in Bloc. You see how it is painful for me to read your ming? So may be I should stop trying to help documenting Bloc Stef

Who is using Pharo Launcher and for what
by Damien Cassou March 6, 2016

March 6, 2016

For my CV, I need to know who is using the stuff I'm doing. If you use the Pharo Launcher, could you please tell me in which context (e.g., which company, open-source project) and what you use it for (e.g., download from CI, standard Pharo)? I don't need long paragraphs, just give me the keywords please.

Rubric mutability issue in RubTextComposer binary search
by Aliaksei Syrel March 5, 2016

March 5, 2016

Hi, seems like there is a rather rare bug in Rubric. I opened an issue with explanation: https://pharo.fogbugz.com/f/cases/15153/Rubric-mutability-issue-in-RubTextC… Would be nice to fix it until release. It was caught in Spotter - as it heavily uses multithreading. Any suggestions are welcome if it is known :) Cheers, Alex
