There was a work with Tiny Core Linux, that could easily be adapted for this.

Re: [Pharo-project] bump: pharo wikipedia page sucks

by ClÃ©ment Bera

I tried to write some more stuff on the French Pharo wiki page : http://fr.wikipedia.org/wiki/Pharo . I moved all the reference to history (birth of smalltalk, relation with companies, forking) in the history section. I tried to focus the page on How to use Pharo and Who uses Pharo. I would like the add a part 'Why Pharo is so great' with all its nice features, which are kind of already in the introduction of the page but I don't know how to present it well and what to focus on. Right now it is more like 'It is smalltalk so it is great' but not 'This is Pharo and these are the reasons why it is great' like they have on Amber web page. Tell me if you like the way I made the French Pharo wiki page I will translate it in English. If you have somewhere a list of great features of Pharo to inspire me so I can write it down in a section. Some more reference on how to learn Smalltalk would be nice too (Adding to Pharo by example 1 & 2) 2013/3/28 Marcus Denker <marcus.denker(a)inria.fr> > > On Mar 28, 2013, at 1:50 PM, stephane ducasse <stephane.ducasse(a)free.fr> > wrote: > > > Yes but also I do not want that people think that I want to have less > Squeak on the pharo page. > > To me a Pharo page should be about: all the history about the squeak > fork is now history for me. > > As a newbie I wante to get excited by pharo not understand the history > of ant fighting while > > elephants are running around.

[Pharo-project] One more project for GSoc 2012

by Serge Stinckwich

One more project idea for Smalltalk GSoC 2013. ---------------------------------------------------------------------- Title: Phratch, a port of Scratch to Pharo 2.0 Level: intermediate Possible mentor: Jannick Laval Possible second mentor: Serge Stinckwich Description: Phratch (https://code.google.com/p/phratch/) is an ongoing port of Scratch and BYOB on Pharo 2.0. The current prototype is still suffering from a lot of bugs. Part of the work will be to add unit tests to the existing project. Even if this is a port to Pharo, we will try to build a new version that is flavor-independent. The long term objective of Phratch is to be able to use it for teaching software engineering and robotics. Technical Details: Pharo and some knowledge of Squeak Benefits to the Student: Student will participate to a very cool project. Benefits to the Community: Scratch will be rebuild on top of a modern Smalltalk version and will benefit from lastest development in the core library and VM. ---------------------------------------------------------------------- -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://doesnotunderstand.org/

[Pharo-project] Ring & namespaces

I see in a few scattered bits and pieces that Ring will support namespaces. So that presumably that will assist in porting VW code to Pharo? How near is that functionality? cheers -ben

Re: [Pharo-project] about a new pharo site

https://lastpass.com/ http://www.atlassian.com/ http://belighted.com/ A common fixture is at the bottom with the footer including a ton of links under the fold.
