ReadWriteStream>>on:
by Ben Coman April 25, 2019

April 25, 2019

I notice... rs := ReadStream on: #( 1 2 3 4 5 6 7 8 9). rs do: [ :x | self inform: x printString ]. ==> shows 10 notifications. but... rws := ReadWriteStream on: #( 1 2 3 4 5 6 7 8 9). rws do: [ :x | self inform: x printString ] ==> nothing it seems because "readLimit" instance variable of ReadWriteStream is zero. Comparing... ReadStream(PositionalStream)>>on: aCollection readLimit := aCollection size. ReadWriteStream(WriteStream)>>on: aCollection readLimit := 0. I wonder if ReadWriteStream should override #on: to set readLimit similar to ReadStream, but are there subtleties in the stream hierarchy I'm not aware of ? cheers -ben

Call for Papers, The Programming Journal, Volume 4, Issue 2
by Fabio Niephaus April 25, 2019

April 25, 2019

======================================================================== The Programming Journal The Art, Science, and Engineering of Programming Call for Papers for Volume 4, Issue 2 http://programming-journal.org/cfp/ Follow us @programmingconf ======================================================================== The Art, Science, and Engineering of Programming was created with the goal of placing the wonderful art of programming on the map of scholarly works. Many academic journals and conferences exist that publish research related to programming, starting with programming languages, software engineering, and expanding to the whole Computer Science field. Yet, many of us feel that, as the field of Computer Science expanded, programming, in itself, has been neglected to a secondary role not worthy of scholarly attention. That is a serious gap, as much of the progress in Computer Science lies on the basis of computer programs, the people who write Them, and the concepts and tools available to them to express computational tasks. The Art, Science, and Engineering of Programming aims at closing this gap by focusing primarily on programming: the art itself (programming styles, pearls, models, languages), the emerging science of understanding what works and what doesnât work in general and in specific contexts, as well as more established engineering and mathematical perspectives. We solicit papers describing work from one of the following perspectives: Art: knowledge and technical skills acquired through practice and personal experiences. Examples include libraries, frameworks, languages, APIs, programming models and styles, programming pearls, and essays about programming. Science (Theoretical): knowledge and technical skills acquired through mathematical formalisms. Examples include formal programming models and proofs. Science (Empirical): knowledge and technical skills acquired through experiments and systematic observations. Examples include user studies and programming-related data mining. Engineering: knowledge and technical skills acquired through designing and building large systems and through calculated application of principles in building those systems. Examples include measurements of artifactsâ properties, development processes and tools, and quality assurance methods. Independent of the type of work, the journal accepts submissions covering several areas of expertise, including but not limited to: - General-purpose programming - Data mining and machine learning programming, and for programming - Database programming - Distributed systems programming - Graphics and GPU programming - Interpreters, virtual machines, and compilers - Metaprogramming and reflection - Model-based development - Modularity and separation of concerns - Parallel and multi-core programming - Program verification - Programming education - Programming environments - Security programming - Social coding - Testing and debugging - User interface programming - Visual and live programming All details, including the selection process are described on http://programming-journal.org/cfp/ Details on the submission processed are available at http://programming-journal.org/submission/ Authors of accepted papers will be invited to present at the <Programming>â20 conference in Porto, Portugal from March 23-26: https://2020.programming-conference.org/ ## Upcoming Deadlines We solicit submissions for the following upcoming deadlines: Submission: June 1 First notification: August 1 Revised submission: September 1 Final notification: September 7 Camera-ready: September 15 Weâll also solicit submissions for Issue 3, for full details, see: https://programming-journal.org/timeline/ ## Standing Review Committee Volume 4 Christophe Scholliers, Ghent University Coen De Roover, Vrije Universiteit Brussel Craig Anslow, Victoria University of Wellington New Zealand Didier Verna, EPITA / LRDE France Diego Garbervetsky University of Buenos Aires Edd Barrett, King's College London Erik Ernst, Google Felienne Hermans, Leiden University Francisco Sant'Anna, Rio de Janeiro State University Friedrich Steimann, FernuniversitÃ¤t Gordana Rakic, University of Novi Sad Guido Salvaneschi, TU Darmstadt Hidehiko Masuhara, Tokyo Institute of Technology Jeremy Gibbons, University of Oxford Jonathan Edwards, US Jun Kato, AIST Japan Luke Church, University of Cambridge Matthew Flatt, University of Utah Michael L.

Re: [Pharo-dev] [vwnc] most energy efficient AI system - challenge of the German Federal Ministry of Education and Research BMBF
by Bernhard HÃ¶fner April 24, 2019

April 24, 2019

Hello group, Bernard Portier from University Brest allowed me to forward his ideas referring to works of different scientists. It may help to concretize an AI-project or to fertilize discussion. I am not an AI-specialist and sorry not to be able to participate on a discussion. Best Regards, Bernhard â¦ Dear Bernhard, This is a summary of work done at University of Brest for mapping Smalltalk computation to hardware. 1) efficiency is concurrency in execution During decades researchers and industry was running behind the work of Xerox PARC on micro- programmed computers, such as the Dorado. The Dorado implemented a pipeline for decoding languages intermediate code developped for this purpose. Smalltalk bytecodes as delivered for Smalltalk-80 were of this kind. Behind the streaming engine that prepared the execution, there was the micro-machine routines translated by PARC into micro-program control executing several internal operations in parallel. The blue book implementation part is just a description of how the instructions are executed. (For those who do not know about micro-programming, there are primers written in the 70's by Michael Flynn to explain link between the instruction set, micro-program structure, and program execution. It takes 1 day to read, understand, and experiment: look at Ci lines that activate concurrent operations from a micro-code word.) [Flynn] Micro-programming, includes Rosin machine, in Computer Architecture 1972. Annex 1. [Dorado] Retrospective, Pier. http://bitsavers.trailing-edge.com/pdf/xerox/parc/techReports/ISL-83 <http://bitsavers.trailing-edge.com/pdf/xerox/parc/techReports/ISL-83>- 1_A_Retrospective_on_the_Dorado_A_High-Performance_Personal_Computer.pdf So, Smalltalk was fast enough in 1980, it was well understood for a machine execution, and became so slow when executed on micro processors, despite valuable efforts at UCBerkeley, Stanford and others. 2) concurrency is now easily available Probably one could implement Rosin machine in few days, plus a compiler to translate a calculator syntax into instruction set for it. Research could rather examine chances to execute high level computer language at the current level of resources as FPGAs devices and shared memory accelerators. In the second case, one can recall that previous generation of massive parallel computers used Smalltalk to model execution. It was the case for Maspar machine which debugger was showing clearly a ParcPlace support to display assertions on parallel (plural) variables. This debugger inspired some work to support parallel execution on GPU as shown in [VanLong]. [VanLong] Master report. Annex 2. http://wsn.univ-brest.fr/pottier/long.pdf <http://wsn.univ-brest.fr/pottier/long.pdf> (See also https://www.mdpi.com/1424-8220/18/7/2323 <https://www.mdpi.com/1424-8220/18/7/2323> about parallel physical simulation) 3) execution and definition of object spaces can replace types. Smalltalk does not have types. Types ease program checking and preparation of execution on machines. Instead, Smalltalk provides classes to resolve call to methods. Instead of relying on class tags, we can also rely on object sets (called contexts), solve binding on these object sets, and produce logic networks that will replace the slow interpretation or execution by one call to a dedicated function block. Computer operative parts are either logic networks, combinational or sequential, defined at boolean level. Thus this schema is the common way to produce operative blocks, even dynamically. The first stage is a high level look-up table tree production organized around method calls, with evolved backtracking memory optimizers. This could be suitable for architectures such as GPUs or memory based nano-architectures. The second stage is mapping to reconfigurable architectures, expecially those oriented to logic, such as FPGAs. The Madeo framework address Smalltalk to technology translation in its different stages address this question, such as: [FCCM96] Smalltalk blocks to logic, 4th IEEE Symposium on FPGAs for Custom Computing Machines (FCCM '96), Napa Valley, CA, USA, April 17-19, 1996. IEEE 1996, ISBN 0-8186-7548-9 also at http://wsn.univ-brest.fr/reports/96/st80-2-FPGA.ps.Z <http://wsn.univ-brest.fr/reports/96/st80-2-FPGA.ps.Z> [SAMOS2002] A LUT based approach for high level synthesis, Shuvra S. Bhattacharyya, E.F. Deprettere, Jurgen Teich, (Eds.), Domain-Specific Processors: Systems, Architectures, Modeling, and Simulation, Hardcover, pp. 261, plus XV, Marcel Dekker, Inc., New York, 2004, ISBN 0-8427-4711-9 also at http://wsn.univ-brest.fr/reports/2002/samos2.pdf <http://wsn.univ-brest.fr/reports/2002/samos2.pdf> 4) Mapping LUT systems to hardware were addressed by two excellent PhD works, one that draws a flattened LUT tree on an FPGA, the other one that address nano technologies, largely connected to Pr Moritz work at Umass. As a conclusion (I hope it is not final), there are large opportunities to improve specific execution speed of Smalltalk engines using new 'back to the future' approaches. We just need to stop doing bad copies of the sacred 40 years implementation, pretending that it is a 'virtual machine' for today, look to GPUs, reconfigurable devices, and new technologies especially those based on low energy and fast physical memories.
