pharo-launcher ppa - 32-bit OS problem

by Ben Coman

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

Re: [Pharo-users] Roassal2 RTDraggable grid and synchronized movement

by Peter UhnÃ¡k

Addendum: generally when it comes to Mouse events, using TRMouse* events should be the way to go? E.g. I want to add a control point when I click somewhere on the line so I could subscribe for TRMouseRightClick announcement. My question however is whether using TRachert events is ok. Shouldn't this be handled at Roassal level as it was done in Roassal1 (ROMouseRightClick)?

Roassal2 RTDraggable grid and synchronized movement

by Peter UhnÃ¡k

While playing with RTMultiLine I thought that it would be nice to have option for RTDraggable elements to snap to a grid / move only by fixed increments - for example the position could only be divisible by 10 (grid size would be 10), so dragging from 20@10 to 26@4 would jump to 30@0. Is something like this possible with current implementation? The second question is: is it possible for element to subscribe for position updates of another element? (I.e. element A watches for movement of element B and moves accordingly). I know I could add both of them to a composite shape or RTGroup (RTDraggable>>groupToDrag:), however I would prefer something more loosely coupled. In RTDraggable>>initializeElement: i found " element when: TRMouseDragging do: [ :e | e element translateBy: e step. e signalUpdate ]" however it is commented out so perhaps there some other way?

Data Narratives with Pharo (Re: Data Science with Pharo?)

by Offray Vladimir Luna CÃ¡rdenas

Hi, Is really nice to see this talk happening. I want to use Pharo for data narratives (it can be open/garage/citizen science or data Journalism) and I have recently talked about this on this list and the ones of Moose and SciSmalltalk, but seems that the thread initialized by Volkert got more traction, so I will continue here, which seems like a better place. I would like to advocate that the conditions for a Notebook for visual data narratives and open/citizen/garage science made in Smalltalk are there now that we have Pharo 3, Roassal and Moose Playgrounds. I think that this notebook could be made essentially by putting these playgrounds ordered in a tree/outliner. I have made a similar argument for a tree like interface for IPython notebooks on [1] and I'm using this tree-like writing experience for my own writing of my PhD Thesis [2] (Spanish) and I have started to explore some visual data narratives in Roassal/Moose[3] (Spanish). [1] http://mutabit.com/mutabit/default/wiki/ipython-deepness [2] http://mutabit.com/offray/static/blog/output/posts/la-forma-en-que-escribo-… [3] http://mutabit.com/offray/static/blog/output/posts/borrachos-bochinche-futb… I'm just making a mockup of this using Moose browsers while I learn Pharo with this problem oriented approach. I will ask in another thread my specific questions about the issues I found while working on this project. I think that the Tudor's video about PostgreSQL and visualization is a glimpse of the possibilities and Kilion work interfacing with blender/python shows that this outline could be even interface with IPython notebooks. Outliners can be a proper metaphor for exploratory computing and writing and as org-mode has shown, this simple but powerful metaphor can be a game changer. This are good times for data narratives in Pharo. I would try to help with this.

Re: [Pharo-users] Data Science with Pharo?

by kilon alios

Python works via integration 50% of its code is written in C. Same applies for its libraries. Tons of ported C/C++ libraries.Before that I was using Delphi a Pascal implementation that was using around the same amount of C++ Windows libraries. Two languages with millions of professional developers worldwide. I assume F# is a .NET language with direct access to .NET libraries. And of course we should not forget several popular java languages with Clojure being the latest example. Not only integration is a popular very successful choice but it wont be an exaggeration to state that it has been the foundation of the modern software industry. So no I don't agree even though my own implementation has a long way to go before its ideal. Of course, integration is always an option ... but not a good one in any case, even if there is a way ... ;-) I have seen your Pharo/Blender video. Nice work ... BW, Volkert Am 31.07.2014 um 12:38 schrieb kilon alios: I dont know anything about data sciences but this looks like the dilema I was into. I love making 3d graphics and I love pharo. But those two dont mix togethere. Available 3d libraries for pharo are nowhere near my needs. As an artist and coder I use Blender and its API. The Blender Api is not even in C so I can wrap it with nativeboost. Its in python. So the whole thing at first seemed too much trouble for little gain. With the help of great pharo people I found the way to exploit Blender via sockets I can use its python API and I can do this even using pharo syntax. To my surpriseb it was easy, fast and simple.Not that I have an issue coding in python. The project is WIP but so far it has been very succesful and it can only get better. So I can only agree with the saying "where there is a will there is a way" Afterall combining programming languages is a very popular choice.
