.pharo file on Pharo 1.4
by Francois Stephany April 18, 2012

April 18, 2012

I remember some discussions about a .pharo(rc) file in the home folder that would be executed every time you launch a Pharo image. Did that eventually make it into the base? Is there a way to load different files like 1. ~/.pharo 2. <imageDir>/.pharo ? Cheers, Francois

[JOB] Young Engineer: Smalltalk VM related
by Marcus Denker April 18, 2012

April 18, 2012

2 year Young Engineer Position =============================== INRIA RMoD is looking for a full-time young engineer for helping with developing our research infrastructure. Young engineer means someone who finished with a degree (Master or Engineer) not longer than 2 years ago. The engineer position is focussed on virtual machine related work. As researchers, we need a system to explore new ideas with. The job of the engineer is to help us by improving the infrastructure we use for our daily work. What this of course means is that it's kind of a cool job: work in a research lab, but no paper writing, no teaching, no administration. In addition: - live in France (one hour from Paris, 1h20 from London, 35 min from Brussels) - try a lot of good beers (our office is just 10km from the border to Belgium) - french food - Smalltalk! (in the form of Pharo) Lille is an active city but not expensive (lot of students...), centrally located with good connections by train to everywhere (including CDG and Brussels airports). The idea of the job is to strengthen RMoD with regard to virtual machine development and improve our research infrastructure. In research we are often faced with doing experiments that need VM changes. We want to be able to make these changes as easy as possible so researchers can focus on trying out new ideas. In particular we are working on an easy to understand and modify research virtual machine that is implemented in Smalltalk. The goal here is not a fast production VM but instead infrastructure that is easy to learn and extend for research experiments. The job will include working on the research VM as well as helping with Pharo related VM level development: - extend and develop the research VM. - implement a simple GC in Smalltalk for this VM. - help with Pharo VM related development (build system, fixes, improvements) - improvement of the NativeBoost native code backend. Therefore we are looking for a candidate with some prior experience with Smalltalk (Pharo/Squeak) and possibly some background in implementation of dynamic languages. - Knowledge in Dynamic Languages, preferably Smalltalk - Compiler construction - Implementation of dynamic langauges (Virtual Machines) - Good knowledge in low-level programming (C, Asm) - English Duration: 24 months Starting date: 2012 October or later Sallary: 2 527,74 euros brut / month Location: Lille (no remote job possible) Needed: - degree (Master or Engineering, 5 years) - need to have finished the degree max 2 years ago.

Native widgets?
by Scott McLaughlin April 18, 2012

April 18, 2012

Hi Guys, I am brand new to this list and please be kind if this is a DEAD HORSE already BUT I searched the archives and could not find much. Does Pharo have any plans for implementing native widgets? It would be a real zinger if this could be done as this sort of thing has always been a sticking point for many people (inside and out of the Smalltalk community at large). Cheers, I love Pharo either way, Scott McLaughlin

GSoC news: 13 stipendiums!
by Janko MivÅ¡ek April 12, 2012

April 12, 2012

Dear Smalltalkers, Wonderful news, we got 13 "slots" from Google, that is, 13 students and their proposals will be accepted for Google and they will receive stipendiums if they will do their projects right. More exactly, part of 4500 USD immediately, part after interim evaluation and part at successful finish of their projects. We have currently 18 paired projects, that is, projects paired with one student among their many proposals. You can see that from project table, see which are currently accepted (column Acc.): http://gsoc2012.esug.org/projects?view=projectTable Now mentors need to review and score those 18 project proposals to indicate which are the best among all that nice proposals and to come with number down to 13. This will happen until next Friday 20.April, when we will finally decide, which 13 students to accept. Google will then officially confirm them in few days after. Best regards Janko & Carla -- Smalltalk GSoC Admin Team http://gsoc2012.esug.org

logging/tallying what is getting garbage collected?
by Paul DeBruicker April 11, 2012

April 11, 2012

Is there a way to learn what is getting garbage collected in an image? In a part of an application I've written the Qwaq profiler & Pharo profiler consistently report that 2 full GC's (3% uptime) and ~400 incremental GC's (9% uptime) are run. That makes me think I'm creating and discarding a bunch of stuff and maybe I don't need to, but I also don't have a strong idea where to begin looking. Thanks Paul
