Cog VM on Raspberry Pi ?

by Sven Van Caekenberghe

Hi, Does a (faster) Cog VM for the Raspberry Pi actually exist ? I tried comparing the latest OpenSmalltalk VM with some older ones, only to find that they are all equally fast (slow actually): pi@raspberrypi ~/Pharo $ ./pharo -nodisplay Pharo.image printVersion [version] 5.0 #50581 "http://files.pharo.org/vm/pharoS/raspbian/latest.zip" pi@raspberrypi ~/Pharo $ ./pharo -nodisplay Pharo.image eval '1 tinyBenchmarks' '167429692 bytecodes/sec; 11160247 sends/sec' "http://www.mirandabanda.org/files/Cog/VM/VM.r3427/cogspurlinuxhtARM-15.33.3…" pi@raspberrypi ~/Pharo $ ./products/phcogspurlinuxhtRPi/pharo -nodisplay Pharo.image eval '1 tinyBenchmarks' '166992824 bytecodes/sec; 11337746 sends/sec' "https://bintray.com/opensmalltalk/vm/download_file?file_path=cog_linux32ARM…" pi@raspberrypi ~/Pharo $ ./products/phcogspurlinuxhtRPi/pharo -nodisplay Pharo.image eval '1 tinyBenchmarks' '166992824 bytecodes/sec; 11337746 sends/sec' That is no significant difference on a RPi 3, at all. Is this normal ? Am I missing something ? Thx, Sven PS: Just for reference, my Mac Book Pro is 10 times faster 1 tinyBenchmarks "'1323852617 bytecodes/sec; 174185794 sends/sec'"

Re: [Pharo-users] Garage sqlite on pharo > 5

Why declare that as dead? It is there and is okay to use. People can update it if needed. Why say this? That's not constructive, man. We need DB access. Pharo without DB access is going nowhere in the industry. Just had a pairing session w/ Doru and guess what? The data I need for Moose/Roassal usage is in a database. -_O Phil On Mon, Oct 17, 2016 at 7:29 PM, stepharo <stepharo(a)free.fr> wrote: > Guillermo created Garage because the consortium asked and payed him to do > and I think that he did it well.

Seaside can not be used with Pharo 60261

by Pierre CHANSON

In #SmalltalkImage>>metacelloPlatformAttributes, #'pharo5.x' #'pharo5.0.xâ have been removed and Seaside does not have configuration for pharo6. Is there a plan to update the configuration of Seaside ? Thanks ! Pierre and Norbert

Guillermo created Garage because the consortium asked and payed him to do and I think that he did it well. Now Guillermo does not use any database during his development and he is busy to work on many important tasks for Pharo. I will ask Guillermo to declare Garage as dead and people should not come and cry that DB is not well supported in Pharo. I never understood why the code of UDBC was not pushed into Garage.

Garage SQLite driver doesn't work on Pharo 5, the FFI API changed and Garage wasn't updated to use UFFI. You have to use Torsten version in UDBC.

[JOB][Research] Postdoc "'Higher level IDEs for BlockChain Technologies"

by Marcus Denker

We are looking to fill a Postdoc position. The candidate should : - hold a PhD degree in Computer Science - be fluent in English (French is an advantage but not required) - have good programming skills Experience with DSLs, IDEs, Models, compilers, code analysis... is a plus. Topic: Higher level IDEs for BlockChain Technologies ==================================================== With Ethereum, BlockChain technology moves from being an implementation technology for virtual currency to being the basis for developing new kinds of software with smart contracts. The goal of this project is to analyse and improve high-level development and analysis tools for this new kind of software. Users like banks and insurance companies need tools that model their processes and level of confidentiality of the information shared though blockchain technology, especially on public blockchains. For this, users need a solution that provides a higher level way to model systems than solidity code or even low-level byte-code. In addition, blockchain based solutions often use multiple programming languages. Especially the later poses a risk for later software maintenance. The goal of this Postdoc is to work on high level IDE / modelling tools for blockchain technology like Ethereum. The plan is to - Analyse the current state of tools and languages in the context of blockchain technologies. - Analyse the current state: modelling tools and processes with a focus in decision processes both in communities and commercial use. - Explore how to improve the state of the art, with a focus on how tools can support users of blockchain solutions. - Realize prototypes for IDEs/modelling tools for Ethereum, possibly using Pharo. Directions to explore will be both related to generating and analysing solidity code as well as complete solutions for users in an industrial setting. - Results will be submitted to be publish in international conferences and journals. The work is a collaboration between Inria Lille (RMOD) and Utocat SAS. Duration : 2 years Salary: 31 644â¬ brut Employer: Inria More information: contact marcus.denker(a)inria.fr Utocat: ====== Utocat was created in October 2014 by ClÃ©ment Francomme to help merchants accepting bitcoin payments and converting it directly in euros. In 2015, Utocat joined the EuraTechnologies acceleration program and pivoted to propose Blockchainiz : the dedicated access platform for Banks and Insurance companies. Laurent Koszyczek and Alexis MÃ©vellec partnered with ClÃ©ment Francomme to improve the technical and commercial aspects. As a Platform As A Service (PAAS), Blockchainiz accompanies projects up to the production stage. Blockchainiz connects the functional processes to the blockchain. Data is not replicated on different IT systems anymore. Blockchain is used as a common repository for every part of the process. Hence, it enables to limit the typing errors, to optimize the costs and delays while the customer experience is improved. More information at: https://www.blockchainiz.io Inria Lille =========== Inria is a research institute dedicated to promoting âscientific excellence in the service of technology transfer and society as a wholeâ. Inria employs a staff of 2700, drawn from the worldâs most prestigious universities, to address the latest challenges in computer science and mathematics. The Institute operates eight Research Centres throughout France. The Inria Lille - Nord Europe Research Centre was founded in 2008 and employs a staff of 360, including 300 scientists working in sixteen research teams. Recognised for its outstanding contribution the socio-economic development of the Nord - Pas-de-Calais Region, the Inria Lille - Nord Europe Research Centre undertakes research in the field of computer science in collaboration with a range of academic, institutional and industrial partners. The strategy of the Centre is to develop an internationally renowned centre of excellence with a significant impact on the City of Lille and its surrounding area. It works to achieve this by pursuing a range of ambitious research projects in such fields of computer science as the intelligence of data and adaptive software systems. Building on the synergies between research and industry, Inria is a major contributor to skills and technology transfer in the field of computer science. https://www.inria.fr/centre/lille RMOD ==== The goal of RMoD is to support remodularization and development of modular object-oriented applications. We tackle this objective from two complementary perspectives: reengineering, and constructs for dynamic languages. In the context of languages, we revisit language concepts such as modules and composition; we are also working on a new generation of reflective systems. We experiment with these programming constructs using Pharo, an open source, reflective, object-oriented language. http://rmod.inria.fr
