the future of squeaksource
by Andrei Vasile Chis May 14, 2013

May 14, 2013

Hi all, Given that SmalltalkHub is now stable we were considering to discontinue SqueakSource. Our idea is to provide a grace period of a couple of months to allow the current active users to migrate their projects to the new service and then simply put squeaksource in read-only mode (simply exposing the directory structure and allowing downloads). What do you think about it ? Are there any good reasons to still keep SqueakSource alive? Cheers, The SCG Team

WideString and FTP Client
by Hilaire Fernandes May 13, 2013

May 13, 2013

Hello, I am using FTP Client to save xml file. Some of these files may be WideString, in that case the FTP Client fails. I got a ByteArray(Object)>>errorImproperStore The code snippet to save is like this (client is ftp client) readonlyStream := ReadStream on: stream contents. client putFileStreamContents: readonlyStream as: aFilename If I convert the content to ByteArray, in that case file is x4 times greater, which should not be the case. Enclosed PharoDebug Thanks Hilaire -- Dr. Geo http://drgeo.eu

May 13, 2013

I've updated nabble to work with the new users list. I'm not exactly sure what's going on with the dev list... is there a new url / email address? I tried http://lists.pharo.org/mailman/listinfo/pharo-project_lists.pharo.org, but got "No such list..." ----- Cheers, Sean -- View this message in context: http://forum.world.st/New-list-s-tp4687029.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hi, As the old setup stopped working last week, we decided to move the mailing list to a new server. New Address: pharo-users(a)lists.pharo.org Web: http://lists.pharo.org/mailman/listinfo/pharo-users_lists.pharo.org -> digest option is preserverd -> others we will fix by hand later this morning (or you can do it yourself now We unsubscribed all users with the "Nomail" option set before retrieving the list of users.

Sockstream vs ZnSocketStream
by Luc Fabresse May 11, 2013

May 11, 2013

Hi all, I am *experimenting* with the replacement of the current network layer with OCEAN. My current plan is to make Zinc tests green while working on the top of OCEAN. And investigate the removal of all the current Network classes (does it play?). After looking at Zinc code, there are few dependencies. Basically, I implemented an OCNSOcketStream (inheriting from SocketStream) and redefined some methods of ZnNetworkingUtils. It seems to play so far (green tests). But then, I discovered that Zodiac introduces a new SocketStream hierarchy (ZdcAbstractSocketStream). Now remember the mails of Sven. So my questions are: 1) Is the intent of ZdcSocketStream to be a future replacement for SocketStream? 2) why ZnNetworkingUtils>>initialize makes use of SocketStream instead of ZdcSocketStream? why the code isn't something like that: ZnNetworkingUtils>>initialize super initialize. self socketStreamClass: (Smalltalk globals at: #ZdcSocketStream ifAbsent: [ SocketStream ]) . self secureSocketStreamClass: (Smalltalk globals at: #ZdcSecureSocketStream ifAbsent: [ nil ]) Moreover, I guess that ZdcSocketStream should speed up things (it says optimized version in the name of the superclass ;-)). So probably, my OCNSOcketStream should better inherit from ZdcSocketStream. Thanks for giving me some light here, Luc

Hi! I just took some time to load and test opendbx in 2.0, with the latest fixes to be able to load ffi. The configuration stable version loads cleanly in Pharo 2.0 and the configuration is available in the configuration browser. I'll continue with Glorp & friends following :) Guille

"Modern" mathematics with Morphic
by Alain Busser May 7, 2013

May 7, 2013

Hi, when I was a child the times were to what was called "modern mathematics". It was quite strange, and we children had to draw Venn diagrams around pentagons (amongst other polygons) or the like. Now modern mathematics have become quite ancient (much like me) and everybody forgot about these "patatoids" (that's how we used to call them in french). Yet nowadays with tablets, exercises can be designed where, instead of drawing a Venn diagram *around* pentagons, the pupil could *move* the pentagons *inside* their Venn diagram (for a linguistic example, imagine moving the letters here: http://en.wikipedia.org/wiki/File:Venn_diagram_gr_la_ru.svg) These exercises where the pupil is to categorize objects or concepts, would be useful also in biology or grammar, if only... Well, ahem, I found out how to devise such exercises in JavaScript with jQuery UI (just declare any element as "draggable", then the sets as "droppable"). But I found out that it seems easy to drop a Morph (element) to another one (set), then make some set theory with "serious games". After all, that's what is shown in "Pharo by example" (drag and drop, and devise one's own method as to what can be dropped or not). Hence my question: Am I the first "genius" to think about this (doubtful) or (more probably) who did already this kind of exercises about set theory? Maybe in Etoys? Maybe not in mathematics but linguistics or other? A short bibliography on the subject: *http://www.cut-the-knot.org/LewisCarroll/tridiagram.shtml (was actually sold in wood with checkers pieces and an instruction book) * http://www.college-de-france.fr/site/stanislas-dehaene/course-2013-01-29-09… the baby learns to speak: There is classification to grasp vocabulary) * http://www.college-de-france.fr/site/stanislas-dehaene/course-2013-02-12-09… following: The baby uses bayesian inference to solve these kind of problems). If I understand well, the minimum age to play to these games is, after Dehaene, 6 months (!) Alain
