DurÃ©e : 6 mois, dÃ©but en fÃ©vrier ou mars (stage de fin d'Ã©tude) Description (Contexte technique, objectifs et dÃ©finition prÃ©cise du travail) : Notre entitÃ© dÃ©veloppe rÃ©guliÃ¨rement des maquettes dâinterfaces homme-machine innovantes. Lâinnovation se situe autant au niveau de lâergonomie quâau niveau du design graphique visuel ou des Ã©lÃ©ments dâinteraction. Le maquettage est souvent utilisÃ© en sÃ©ance avec les opÃ©rationnels, dâoÃ¹ lâemploi dâun langage dynamique comme Smalltalk permettant la modification rapide (et en sÃ©ance) du code et des Ã©lÃ©ments dâinteraction. Le maquettage/prototypage des interfaces Homme-Machine est donc actuellement rÃ©alisÃ© sous SMOCK, un framework de maquettage dÃ©veloppÃ© en Smalltalk Visualworks (Commercial). De nombreux Smalltalk existent sur le marchÃ©, cependant une communautÃ© parmi les autres semble de plus en plus active et moderne, Ã la fois en terme de langage et dâaspects interfaces homme machine : la communautÃ© Smalltalk Pharo (OpenSource). Nous souhaitons expÃ©rimenter les apports de Pharo en terme dâinterfaces homme-machine innovantes. Pour ce faire nous proposons au candidat dâeffectuer un portage de notre framework de maquettage composÃ© de SCM (modÃ¨le en composant) et de CADE (Framework orientÃ© dessin et animations). Un exemple dâihm utilisant les Ã©lÃ©ments portÃ©s validera le travail effectuÃ©. CONNAISSANCES SOUHAITEES : Le stagiaire devra avoir une connaissance du Smalltalk ou Ãªtre motivÃ© par lâapprentissage de celui-ci. Il devra ensuite Ãªtre motivÃ© par la conception dâinterface homme machine de nouvelles gÃ©nÃ©rations et novatrices.

Browsing, I found CFTunneledHttpClient, but the protocol of this class is different from the missing one. Furthermore, I don't understand where this code should be located, so that self reference makes sense. I'm using Pharo 1.3 , as I think it is the Pharo version contemporary with this package and post. Is there some updated documentation for this? is someone using this package or connecting to twitter from pharo? Thanks af

The primitives are in AioPlugin (http://www.squeaksource.com/AioPlugin/) which connects to the low level select() implementation that Ian Piumarta developed for the unix VMs. I think that this works on Mac and on Cog VMs also if the plugin is provided (but it will not work on Windows). Note that the socket that you use in the image may already be using select() to respond to incoming data. HTH, Dave

Bag of Permutations

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?

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

Re: [Pharo-users] SHA256 hashing with secret key..

by StÃ©phane Ducasse

to me it shows that the package crypto should be improved. So publish a new version with the helper methods once you get the right way of making it work. We are all newbies in a domain or another one and I want a system for newbies (with documentation, nice comment, API, testsâ¦.).

Pharo on Ubuntu ARM

by Marc Hanisch

Hello, I'm running Ubuntu ARM (armhf) on my Toshiba AC100. With the help of apt-get I've installed the squeak-vm and the squeak-image, which both run fine. Now I've downloaded the Pharo-image, but could not find the cog-vm for ARM. Running the Pharo-image with the squeak-vm just gives me a segmentation fault: -1550458048 [] in ByteSymbol>? /usr/bin/squeak: line 277: 4603 Segmentation fault (core dumped) $VM I don't know if it is in general possible to run the image with the squeak-vm. Does an ARM-build for the cog-vm exists? Thanks in advance, Marc

I've downloaded the Cog-mac.zip from: http://www.pharo-project.org/pharo-download/unstable-2-0 How can I find out the version/revision number? It would be cool to have the number in the file name.

You need an HMAC signed SHA256 secret. https://en.wikipedia.org/wiki/HMAC https://en.wikipedia.org/wiki/SHA-2 First step is to get the correct SHA256 part then the second step is to make it the correct HMAC Does that help?
