Data Science with Pharo?
by volkert＠nivoba.de Aug. 3, 2014

Here a really nice video on interactive data aquiring, analysis und visualization with F#. http://channel9.msdn.com/posts/Understanding-the-World-with-F Is this the way Pharo + Roassal + ... goes? Ok, we have moose, but a i understand it puts the focus on sw analysis and sw visualization. What about a new easy to use and interactive data science platform?

Trying to understand the "display: children:" messages of Moose browsers.
by Offray Vladimir Luna CÃ¡rdenas Aug. 3, 2014

Aug. 3, 2014

Hi, I'm trying to understand the workings of the "display: children:" message of Moose Browsers. Based on the Help Browser example, I have write a node object which contains a header, a body and a ordered collection of Children, wich are other nodes. Now I would like to use moose browsers to navigate a tree made of such nodes. For that I am modifying the "packagesIn:" tree of the PBE2 book example in the Moose chapter. I have something like this: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= UbakyeBrowser>>packagesIn: constructor | defaultTree | defaultTree := UbakyeNode new. defaultTree becomeDefaultTree. constructor tree display: [:treeHeaders | treeHeaders := defaultTree headers]; children: [:currentNode | self headersOf: currentNode ]; format: #asString -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= The display part is working just because I'm sending a collection of node names (headers), but I don't know how to relate the current selected node with the things that should be shown by the "children:" message. Any help on this is appreciated. By the way, I would like to share my code and point to it, instead of sharing just cut and pasted snippets, because may be I'm doing tons of errors in a lot of places. I have already asked in a separate thread about how to sync local cache and SmalltalkHub repos. Cheers, Offray

Syncing local cache and SmalltalkHub

-------- Original Message -------- Subject: Syncing local cache and SmalltalkHub Date: Thu, 31 Jul 2014 12:12:29 -0500 From: Offray Vladimir Luna CÃ¡rdenas <offray(a)riseup.net> To: pharo-users(a)lists.gforge.inria.fr Hi, I have my outliner buggy mockup on local cache, and I would like to share the code and point to it online using SmalltalkHub for my questions. I have followed the chapter on Source code management with Monticello y PBE2, and it says that you can have your code on SmalltalkHub, but says nothing about how to sync from local cache to your SmalltalkHub account. Can some one could point me the way to do it? Cheers, Offray

Hello

Hello I'm totally new to Pharo and Smalltalk, but not new to programming. I want to learn Pharo and Smalltalk especially to use Moose, Roasall and other data visualization frameworks. Where should I start? I have lot of time to study and want something intensive with exercises and a solid theory background. thanks Soseki Ichiro -- View this message in context: http://forum.world.st/Hello-tp4771473.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Dear All, The chapter âQuickStartâ is now online on http://agilevisualization.com This chapter comes with some examples about using Roassal. It would really help us if some could read it and give us feedback. Feel free to send us feedback on hello(a)agilevisualization.com Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

pharo-launcher ppa - 32-bit OS problem
by Ben Coman Aug. 1, 2014

Aug. 1, 2014

I successfully used the "Ubuntu ppa" instructions at http://pharo.org/download to install Pharo Launcher on 64-bit Linux Mint 17, but doing the same on 32-bit Linux Mint 17 gives an error... $ sudo apt-get install pharo-launcher The following packages have unmet dependencies: pharo-launcher : Depends: pharo-vm-desktop:i386 but it is not installable E: Unable to correct problems, you have held broken packages. This is both without and with the second line "sudo dpkg --add-architecture i386" since I wasn't sure if it made sense to do this when already $ dpkg --print-architecture # reports... i386 The following worked without error $ sudo apt-get install pharo-vm-desktop I had a look at the package info with... $ sudo apt-get download pharo-launcher $ cp /var/cache/apt/pharo-launcher*deb /tmp $ cd /tmp $ dpkg -I pharo-launcher*deb which displayed... Architecture: any Depends: pharo-vm-desktop:386 and it seemed to me the hardcoding of :386 might be the trouble, and wondered if the following would work better for both 32-bit and 64-bit OS? Architecture: i386 Depends: pharo-vm-desktop I repackaged the deb per instructions at http://ailoo.net/2009/06/repack-a-deb-archive-with-dpkg-deb as... Package: pharo-launcher-test With a local repository set up per https://help.ubuntu.com/community/Repositories/Personal the following worked. $ sudo apt-get --allow-unauthenticated install pharo-launcher-test $ pharo However I no longer have the 64-bit LinuxMint install to test if this change is compatible. Can someone do this? cheers, Ben
