Smalltalk Impact
by Sean DeNigris Jan. 20, 2014

Jan. 20, 2014

Last week I attended an event at the The Metropolitan Museum of Art Media Lab. While networking, two educators told me that they use Scratch with their kidsâ¦ not knowing I knew anything about it. They showed me some of their students' projects and were so proud and excited. They were also intrigued when I shared Scratch's lineage, connecting the dots back to the dynabook vision of computers as a metamedium to transform human thought. I talked about Smalltalk, and directed them to Phratch - and its ability to create tiles - as a bridge between tile-based and "full fledged" programming, for those students who yearn for more expressive power. I thought you'd like to know that all of our work is rippling out in ways we can't imagineâ¦ Cheers, Sean

PhD Position on Dynamic Reflective Language Integration with FPGAs for Robotic Applications
by jannik laval Jan. 20, 2014

Jan. 20, 2014

The position is available now. Interested candidates may apply as soon as possible. *Title:* Ph.D. Student Position on Dynamic Reflective Language Integration with FPGAs for Robotic Applications *Location:* Mines de Douai and ENSTA Brest (France) *Advisor and contacts:* Noury Bouraqadi (noury.bouraqadi(a)mines-douai.fr) Luc Fabresse (luc.fabresse(a)mines-douai.fr) LoÃ¯c Lagadec (loic.lagadec(a)ensta-bretagne.fr) Jannik Laval (jannik.laval(a)mines-douai.fr) *Profile:* the candidate must must hold a recent Master of Science degree in Computer Science or Software Engineering and must have solid skills in dynamic reflective language (Smalltalk). *Description of the work:* The goal of this PhD is to study Smalltalk integration with FPGAs for robotic applications. This integration will enable us get the best from both worlds. Developers are provided with a high-level dynamic reflective language (Smalltalk) for building and debugging their applications. Still, we can have high performances by projecting part of the programs into FPGAs. These reconfigurable hardware chips can achieve performance faster than C programs, while consuming much less energy. The work to do can decompose into the following tasks: -Build reference robotic applications fully in Pharo Smalltalk using actual robots (see http://car.mines-douai.fr/robots/) -Analyze these applications to identify critical parts to project on FPGAs to significantly increase performances (speed, energy) -Do the actual projection to FPGA and evaluate performances of the transformed applications -Generalize the approach and define a methodology for turning Smalltalk code into FPGA -Propose a solution to automate the methodology The Ph.D student will receive a grant which net amount is approximately 1420 euros per month for 3 years (36 months). He will be co-supervised by LoÃ¯c Lagadec from the ENSTA-Bretagne (Lab-STICC, Brest) and Jannik Laval, Luc Fabresse and Noury Bouraqadi from Ecole des Mines de Douai (CAR, http://car.mines-douai.fr/) The first 18th month will be spent in Douai (Lille area), while the last half of the PhD will be spent in Brest. However, during the full 3 years, there will be a strong interaction with co-supervisers from both labs. *Bibliography:* -A Robust Layered Control System For A Mobile Robot. R. Brooks.

unload all
by Pavel Krivanek Jan. 20, 2014

Jan. 20, 2014

Hi, I finally successfully created a script that is able to unload everything *by Monticello* except kernel packages, network, Monticello, Gofer and related packages. I will setup a job when Jenkins will be healthy again. It uses several temporary patches that we need to solve properly: - make NativeBoost optional - make UserManager optional - small super-easy issue https://pharo.fogbugz .com/f/cases/12679/change-package-of-ClassTrait-soleInstance The size of resultant image is about 6.6 MB, 4.9 MB without MC data and caches. BTW in the full image Monticello data have about 5MB. The image has no Undeclared nor obsolete classes and is really able to load something using Gofer. With some care we can make it usable base for the next remodularizationeffort. Cheers, -- Pavel

[ANN] MessageTally in GTInspector
by Tudor Girba Jan. 20, 2014

Jan. 20, 2014

Hi, The GTInspector just became a performance analysis tool, too. You can simply inspect a MessageTally and you get several useful views that help you identify performance problems. You can read a more detailed description here: http://www.humane-assessment.com/blog/assessing-pharo-performance-with-gtin… As an appetizer, I attached a screenshot with a Graph-ET chart (thank you Daniel Aviv for developing this engine). [image: Inline image 1] To play with the code, you can just work in the latest Moose 5.0 image: https://ci.inria.fr/moose/job/moose-5.0/lastSuccessfulBuild/artifact/moose-… Please let me know what you think. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

Question on Unclassified / _UnpackagedPackage
by Goubier Thierry Jan. 20, 2014

Jan. 20, 2014

Hi all, I'm looking at classes without package and/or without system category. Nautilus offers a _UnpackagedPackage; some code in Class use 'Unclassified' when compiling without explicit category. So far, creating an 'Unclassified' class does not register in _UnpackagedPackage (however, I do see an 'Unclassified' RPackage with, of course, no MCWorkingCopy associated). anybody knows how this is supposed to work?
