Who uses Exception >> #resignalAs: ? Because I would like to change to from ------------------------------------------------------------------- resignalAs: replacementException "Signal an alternative exception in place of the receiver." self resumeUnchecked: replacementException signal ------------------------------------------------------------------- to ------------------------------------------------------------------- resignalAs: replacementException "Signal an alternative exception in place of the receiver." ^ replacementException signalIn: signalContext ------------------------------------------------------------------- In my opinion better of course ;). Facts: ------- 1) there are no users of #resignalAs: in the image 2) my change doesn't break the Exception tests

Ph.D. Student Position on Dynamic Reflective Language Integration with FPGAs for Robotic Applications
by jannik.laval July 11, 2013

July 11, 2013

Dear Smalltalkers, We are searching for a PhD Student. Following you will find the proposal. Best regards, ====== Location: Mines de Douai and ENSTA Brest (France) Advisor and contacts: Noury Bouraqadi, Luc Fabresse, Jannik Laval (car(a)mines-douai.fr, website: http://car.mines-douai.fr/) LoÃ¯c Lagadec (loic.lagadec(a)ensta-bretagne.fr) Profile: the candidate must hold a recent Master of Science degree in Computer Science or Software Engineering and must have solid skills in dynamic reflective language and OOP. 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.
