Little how to
by stepharo March 9, 2016

March 9, 2016

Hi guys for the mooc I would like have a list of how to that students should look in the system and implement. The idea is to show to the participants that Pharo is open and that they can find information. For example, - extracting a sprite from a png file - access a time service of the web Now I would love to get your ideas and their solution. Stef

Call about Numerical Methods in Pharo :)
by stepharo March 9, 2016

March 9, 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

strange array instance
by Pavel Krivanek March 9, 2016

Hi, there is a strange array of size 1024 in the Pharo image that is not eaten by garbage collector even if no object points to it. I guess it is related to Spur. ((Array allInstances select: [ :i | i size = 1024 ]) select: [ :a | a second = SmallInteger ]) pointersTo What is it and is it accessible somehow? Cheers, -- Pavel
