This is strange because I do not see why it would crash. Do you have a log file of the crash?

Re: [Pharo-users] Bag of Permutations

I don't know why you'd need to make a copy inside the block but this works: | m p | m := #(1 2 3). p := Bag new. m permutationsDo: [:each | Transcript show: each ; cr. p add: each copy. Transcript show: p ; cr. ]. Transcript show: '------'; cr. p do: [:each| Transcript show: each; cr] The Transcript shows: #(1 2 3) a Bag(#(1 2 3)) #(1 3 2) a Bag(#(1 2 3) #(1 3 2)) #(2 1 3) a Bag(#(1 2 3) #(1 3 2) #(2 1 3)) #(2 3 1) a Bag(#(2 3 1) #(1 2 3) #(1 3 2) #(2 1 3)) #(3 2 1) a Bag(#(2 3 1) #(1 2 3) #(1 3 2) #(2 1 3) #(3 2 1)) #(3 1 2) a Bag(#(2 3 1) #(1 2 3) #(1 3 2) #(2 1 3) #(3 2 1) #(3 1 2)) ------ #(2 3 1) #(1 2 3) #(1 3 2) #(2 1 3) #(3 2 1) #(3 1 2) On 10/01/2012 10:14 AM, Ginny Hendry wrote: > I would like to get a collection of permutations of another > collection but I can't make it work. > > This ends up incorrectly with the same element many times in Bag p: > > | m p | > m := #(1 2 3). > p := Bag new. > m permutationsDo: [:each | > Transcript show: each ; cr. > p add: each. > Transcript show: p ; cr. > ]. > Transcript show: '------'; cr. > p do: [:each| Transcript show: each; cr] > > But this very similar code ends up correctly with different > elements in Bag p: > > | m p | > m := #(1 2 3). > p := Bag new. > m do: [:each | > Transcript show: each ; cr. > p add: each. > Transcript show: p ; cr. > ]. > Transcript show: '------'; cr. > p do: [:each| Transcript show: each; cr] > > Any ideas about what am I doing wrong?

Bag of Permutations

by Ginny Hendry

I would like to get a collection of permutations of another collection but I can't make it work. This ends up incorrectly with the same element many times in Bag p: | m p | m := #(1 2 3). p := Bag new. m permutationsDo: [:each | Transcript show: each ; cr. p add: each. Transcript show: p ; cr. ]. Transcript show: '------'; cr. p do: [:each| Transcript show: each; cr] But this very similar code ends up correctly with different elements in Bag p: | m p | m := #(1 2 3). p := Bag new. m do: [:each | Transcript show: each ; cr. p add: each. Transcript show: p ; cr. ]. Transcript show: '------'; cr. p do: [:each| Transcript show: each; cr] Any ideas about what am I doing wrong? How can I get a collection of permutations? Working in Pharo 1.4 one-click for Mac OSX. Thanks. -Ginny

I think it crashed because the Toshiba AC100 has just 512MB of RAM. Greetings, Marc -- â Esperanto - Lingvo internacia â http://www.esperanto.de â http://e-gikoj.com â

persist data across a redirect..

by sergio_101

the way the facebook authorization scheme works is as follows: 1. on the first go round, facebook sends a POST with some data in it that needs to be parsed to pull an authorization code out of it. 2. if the app isn't authorized, i need to redirect to an authorization dialog to so that the user can authorize my app. 3. once the user does that, my app receives an oauth code, and i am on my way. i have everything working, except, i am not sure where to store the authorization code.. in my main component's renderOn, it looks to see if the a instance variable 'oauthToken' is set. if not, it renders some javascript that is really just a redirect to the facebook authorization screen. once the app is authorized, 'oauthToken' is set to the correct value. then, the authorization dialog sends the request BACK to the root url.. everything works correctly..BUT.. on the second time back, the redirect from facebook, it looks like it starts a brand new session (there is a new instance of the main component created). i was hoping that this would all be one session, and that i could just set an instance variable once, and not even touch the session, but i don't think this is going to happen. plus, it looks like i will be firing up a new session on return anyway, so what i have saved in session will be lost. anyone have any ideas on how to cleanly persist this variable after facebook's redirect? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101
