All collections with an Array as backing store do not perform well in a large memory setting. That's not only a problem in a 64-bit image. Stephan

[Pharo-project] Collection >> collectDistinct: ??
by Mariano Martinez Peck March 12, 2010

March 12, 2010

Hi. I was needing something like the SQL select distinct, that doesn't take into account repeated objects. I didn't found anything useful in Collection, and thus, I have implemented this: Collection >> collectDistinct: aBlock collectDistinct: aBlock "Evaluate aBlock with each of the receiver's elements as the argument. Collect the resulting values into a Set, thus repeated objects will not be present. Answer the new collection." | newSet | newSet := self species new asSet. self do: [:each | newSet add: (aBlock value: each)]. ^ newSet Is there a better way ? Do you think it make sense to put this in Pharo ? Cheers Mariano

[Pharo-project] We applied!!!
by Mariano Martinez Peck March 12, 2010

March 12, 2010

See the final application at: http://gsoc2010.esug.org/application.html. See final project ideas at: http://gsoc2010.esug.org/ideas.html It seems that we managed to activate our whole community to propose a record number of projects in a record short time this year. We namely have 35 project ideas (comparing to 15 in 2009, 18 in 2008, 24 in 2007) Proposed projects seem also of a high quality and this won't get unnoticed by Google, we can be sure. So, let we keep fingers crossed for a few days until Thursday, 16.March for Google to decide... Thanks to all for the project submissions, ideas, feedback and corrections! Janko and Mariano

Not a big fancy report for big bosses of course. But a result in some easy understand form to base further decisions on. > Consensus doesn't accomplish anything. Many truly great things are not understood by a voting majority. A mixture of pride and reward is required to get work done. Few would anonymously give away great ideas. Who is going to implement a commonly recognized "great" idea that is not their own? Usually the quality and results of work lacking incentive are mediocre at best. What about the destructive personalities that take pride in destroying good ideas? It is those types that love to participate in consensus groups because that is how they derive satisfaction. The outcome of what you are proposing would be the common (mis)understanding of problems. Consensus doesn't mean that understanding is correct. Consensus doesn't mean that what is proposed will really accomplish anything. Consensus doesn't get the goals actually achieved. Consensus work does little more than mimic what someone else already struggled to prove successful--diminishing incentive from people who deserve the credit. I've never seen anything good come from a consensus. About consensus: I don't have in mind bad compromises etc, but moving the initial majory voting result from too frequent 51/49% slowly closer to ideal 100/0%. By continuing the argumented debate, revoting etc. Remember that majory voting usualy leaves a substantial percent of voters unsatisfied, which is not good and can lead to polarization of a community. Seeking a consensus is a technique to lower this percent. But this is also a cultural thing, Japanese are for instance more inclined to consensus seeking. About destructive personalities: Anonymity is here to solve and silence such people, because everyone can say what has in his mind freely, without fear of exposure and any represalies of any form. Also, the result of such idea gathering and voting is a strong argument against such the people. We have just now an example in Squeak community and with a collection of "ideas" with such a tool I'm sure we'd measure what a community really think quite precisely and this will be an undeniable argument against the guy, who thinks that only he knows well, what the community really think. About pride and reward: Well, authors of the best ideas at the end can be announced, but on the other side author of such idea will know that he wins even if he stays anonymous. Also remember that such a tool is not good for every possible case. I think the best is for collecting initial ideas as freely as possible and measuring the opinion about them from others. This can then be a base for the real decisions. Best regards Janko > Better to act in an environment that forms a cycle of individual liberty and reward. Create a market for change where people can work for reward. Pride is the dominant incentive in young markets. Incentive markets originate from pride in the hope to establish a market for financial reward. > > "Stalemate"? That means that there is a gatekeeper blocking change or destroying incentives. What stops a Linux developer from evolving code? Obviously the cost of getting Microsoft to change their code would be a disincentive. Smalltalk is between those extremes, but with fewer incentives to overcome the cost-of-change. To me, Smalltalk development is about rapid evolution. Years ago I stopped caring about releasing code though gatekeepers. I expect you'll find many people have already done really great things but are not sharing them. That is a market opportunity for someone smart enough to develop it. > > Paul Baumann > > > > -----Original Message----- > From: vwnc-bounces(a)cs.uiuc.edu [mailto:vwnc-bounces@cs.uiuc.edu] On Behalf Of Janko MivÅ¡ek > Sent: Thursday, March 11, 2010 6:15 AM > To: Squeak; Pharo-project(a)lists.gforge.inria.fr; GNU Smalltalk; GemStone Seaside beta discussion; 'VWNC' > Subject: [vwnc] GSoC idea: Brainstorming portal for better community decision process > > Dear Smalltalkers, > > Becasue we have quite some problems in a community with seeking a consensus on important questions, from organization ones and on, I came to idea to build a tool for help.

[Pharo-project] image overload
by Eliot Miranda March 12, 2010

March 12, 2010

Hi All, I'm sure Im opening an old topic but anyway, as I was riding the train to work today I saw a shop called "Audio Images" and it struck me how overloaded the term image is, and how poor a term for the contents of the image file Smalltalk image is. What's in the image is a snapshot of... almost the entire system (minus platform-specific virtual machine and possibly minus sources). So Smalltalk system file would be a far better term and stsys a more unique file extension (and according to Wikipedia STS is unused too). I can imagine that changing form image would be hugely expensive in documentation terms (docs, websites, workspaces, etc, etc). But I can at least dream of a better term. P.S. I know, wasting one's time worrying about names. Almost as bad as worrying about colours "And the wheel," said the Captain, "What about this wheel thingy? It sounds a terribly interesting project." "Ah," said the marketing girl, "Well, we're having a little difficulty there." "Difficulty?" exclaimed Ford. "Difficulty? What do you mean, difficulty? It's the single simplest machine in the entire Universe!" The marketing girl soured him with a look. "Alright, Mr. Wiseguy," she said, "if you're so clever, you tell us what colour it should be."

[Pharo-project] Class comments are in the .sources ?
by Mariano Martinez Peck March 12, 2010

March 12, 2010

Hi folks. I was playing a bit with the ClassOrganizer stuff. I thought that class comments were in the image, but it seems they are kept in the .source. Is this correct ? They are ALWAYS kept in the .sources? I know that the class of the instancia variable "classComment" in the ClassOrganizer can be Text, ByteString or even RemoteString. I though that only those who have RemoteString were in .sources but it seems all are there. I am correct ? is this the desired behavior ? Thanks! Mariano
