Matrix error
by Offray Vladimir Luna CÃ¡rdenas Oct. 24, 2015

Oct. 24, 2015

Hi, I was testing the code here: =[1]========= | medMatrix | medMatrix := Matrix new. medMatrix numberOfColumns: 7; numberOfRows: 5. 1 to: medMatrix numberOfRows do: [:row | 1 to: medMatrix numberOfColumns do: [ :column | "medMatrix at: row at: column put: 0." Transcript show: row asString, ',', column asString, '|'. ]. Transcript show: cr. ]. medMatrix. =========== and I got a transcript like this: =[2]========== 1,1|1,2|1,3|1,4|1,5|1,6|1,7|nil2,1|2,2|2,3|2,4|2,5|2,6|2,7|nil3,1|3,2|3,3|3,4|3,5|3,6|3,7|nil4,1|4,2|4,3|4,4|4,5|4,6|4,7|nil5,1|5,2|5,3|5,4|5,5|5,6|5,7|nil'[Spotter] Exception while collecting processors for <Matrix>: Error: Instances of UndefinedObject are not indexable' '[Spotter] Exception while collecting processors for <Matrix>: Error: Instances of UndefinedObject are not indexable' '[Spotter] Exception while collecting processors for <Matrix>: Error: Instances of UndefinedObject are not indexable' '[Spotter] Exception while collecting processors for <Matrix>: Error: Instances of UndefinedObject are not indexable' ============= I tried also with SciSmalltalk matrix, but they seem to be only square ones. What's is the problem with matrices? Why I'm getting Undefined Objects while trying to iterate or populate them? Thanks, Offray

by Offray Vladimir Luna CÃ¡rdenas Oct. 24, 2015

Oct. 24, 2015

Hi, In my effort to more create more meaningful computer mediated experiences for me and other and to use Pharo as a medium for that I have proposed the following project: --- - Name: Data Kitchen: Frictionless data, moldable tools, pocket infrastructures & permanent workshops for community empowerment - url: https://www.newschallenge.org/challenge/data/entries/data-kitchen-frictionl… --- It combines the ideas of moldable tools, agile visualization in this community with some of other like frictionless data, by Open Knowledge Foundation and what I call "pocket infrastructures". Any feedback is welcomed. You can make it here in this list, but if you can made it on their platform, from a simple "heart" (+1) or drop me a line, it would be greatly appreciated and it will help to make more visible the project. Thanks, Offray

#collect:as:Dictionary
by Peter UhnÃ¡k Oct. 24, 2015

Oct. 24, 2015

Hi, is this intentional behavior? #(a b c) collect: [ :each | each -> each first asciiValue ] as: Dictionary. "a Dictionary(1->#a->97 2->#b->98 3->#c->99 )" (#(a b c) collect: [ :each | each -> each first asciiValue ]) asDictionary. "a Dictionary(#a->97 #b->98 #c->99 )" I would expect that collect:as: for Dictionaries would act in the same way as #asDictionary. {eter

Fwd: FOSDEM 2016 devroom selection
by stephan Oct. 23, 2015

Oct. 23, 2015

-------- Forwarded Message -------- Subject: FOSDEM 2016 devroom selection Date: Thu, 22 Oct 2015 13:18:25 +0200 From: Johan van Selst <johans(a)fosdem.org> To: devrooms(a)fosdem.org Hi, I'm sorry to inform you that we declined your devroom proposal. To clarify, your request was perfectly valid, but we had to choose. Unfortunately we do not have a sufficient number of rooms at our disposal to cover all requests. This year, we had over 60 requests for a devroom and were only able to accept 37 of those. However, some requests have been combined into a single devroom. Nevertheless, there are other ways to participate in FOSDEM too. You can still: - have a stand at FOSDEM, - hold a 15 minute 'lightning talk' in one of the biggest rooms, - speak in one of the other devrooms (CfP to follow), - hold a session in the community meeting room (new; CfP to follow). The full list of accepted devrooms will be published on the FOSDEM website later this week. On behalf of the FOSDEM devroom team, Johan van Selst

Feedback on #assert: vs. #assert:equals:
by Nahuel Garbezza Oct. 23, 2015

Oct. 23, 2015

Hi everyone, I'm using Pharo for teaching and we use TDD since the beginning. I've noticed that if you use #assert: on a test, like this: self assert: object messageReturningBoolean It gives you strange results in terms of feedback if the result is not a boolean. I would expect an AssertionFailed (yellow test) but I got a NonBooleanReceiver (red test). What we do in our course is to write the assertion like this: self assert: object messageReturningBoolean equals: true So we got a "expected true but was <other object>" error which is a lot more helpful to the students. I was thinking that is better to have #assert: implementation based on #assert:equals:. It is like saying #assert:equals: is the "primitive" assertion message, which makes sense to me since you are always comparing if an object is equal to another, there's no reason to handle the booleans' case differently. What do you think? Thank you! Nahuel

Hello, Is it me, or is there a problem with WideString and Artefact? The following produces an empty page: page add: ((PDFFormattedTextElement from: 10mm @ 20mm to: 277mm @ 30mm) alignment: PDFAlignment left; text: 'Argent de poche : 1â¬'). The text is WideString. Removing the â¬, it went ok. Hilaire -- Dr. Geo http://drgeo.eu http://google.com/+DrgeoEu

crashed image ?
by Jean Baptiste Arnaud Oct. 21, 2015

Oct. 21, 2015

Hi, maybe a useful question :-) I crashed a image :-) And I ask myself: - There are a more advance (thinking bout maybe epicea) change browser ? Because a list of 1293801283 changes and just 1 options select all (which is broken you should use shortcut) will not really helpme - Oz is usable on 5.0 image ? That can be the more efficient solution. Just want to stop some process. I exactly know what trigger the crash. And the "Igor hex tricksâ will not work here. Export my code. - why cannot drag a .change on another image anymore ? bug or choice ? Best Regards JB jbaptiste.arnaud(a)gmail.com
