[JOB] Pharo Engineer, IoT
by Marcus Denker Dec. 12, 2015

Dec. 12, 2015

Engineer Position 1 Year =================== INRIA RMoD and the Pharo Consortium are looking for a full-time engineer for helping with developing Pharo. The focus of this job is "Pharo on embedded and mobile devices for the internet of things". - Embedded Pharo on ARM The currently available class of ARM devices (BeagleBone, Raspberry PI) are a very interesting platform for Pharo. The engineer should strengthen the existing efforts to get Pharo working on these platforms. - Pharo on Android Improve the support of Android devices. With Pharo6, we will migrate to a complete new design and implementation of UI, Windowing and graphics. The engineer will work on making these features available on Android devices. - Pharo itself The engineer is expected to be actively involved in helping to improve the infrastructure that the Pharo community used (CI server for continues integration, interplay with issue tracking) and to actively help with day-to-day bug fixing. We are looking for a candidate with some prior experience with Pharo - Knowledge in Dynamic Languages - Experience with mobile development is a plus - English Work in a research lab, but no paper writing, no teaching, no administration. In addition: - centrally located (one hour from Paris, 1h20 from London, 35 min from Brussels) - try a lot of good beer (our office is just 10km from the border to Belgium) - Program with Pharo all day! 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). Duration: 12 month Starting date: as soon as possible (Spring 2016) Salary: 2600-3200 euros brut / month, depending on experience Location: Lille (no remote job possible) More about Pharo: http://www.pharo.org INRIA RMOD: http://rmod.lille.inria.fr INRIA Lille: http://www.inria.fr/lille/ INRIA in General: http://www.inria.fr Lille: http://en.wikipedia.org/wiki/Lille http://wikitravel.org/en/Lille Do not hesitate to contact us for more information.

[JOB] Pharo Engineer, Infrastructure
by Marcus Denker Dec. 12, 2015

Dec. 12, 2015

Engineer Position 1 year + 1 year ================================== INRIA RMoD and the Pharo Consortium are looking for a full-time engineer for helping with developing Pharo and the infrastructure around it. The focus of this job is the infrastructure that Pharo provides to external projects as well as the infrastructure we use to develop Pharo itself. - Infrastructure for external projects Pharo is used in many contexts: an ever growing number of frameworks are contributed by the community. Pharo already provides CI infrastructure, but what is missing is the automatic check of collections of frameworks and libraries. We want to provides validated "distributions" focussing on certain tasks, for example Pharo for Web development. - Pharo and Git Pharo has some support for using Git. The goal is to improve the support of git and other versioning systems. - Pharo itself The engineer is expected to be actively involved in helping to improve the infrastructure that the Pharo community uses (CI server for continues integration, interplay with issue tracking) and to actively help with day-to-day bug fixing. We are looking for a candidate with prior experience with Pharo and possibly some background in continuous integration: - Knowledge in Dynamic Languages - Continuous integration and deployment - English Work in a research lab, but no paper writing, no teaching, no administration. In addition: - Centrally located (one hour from Paris, 1h20 from London, 35 min from Brussels) - Try a lot of good beer (our office is just 10km from the border to Belgium) - Program with Pharo all day! 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). Duration: 12 + 12 months Starting date: Feb or March 2016 Salary: 2600-3200 euros brut / month, depending on experience Location: Lille (no remote job possible) More about Pharo: http://www.pharo.org INRIA RMOD: http://rmod.lille.inria.fr INRIA Lille: http://www.inria.fr/lille/ INRIA in General: http://www.inria.fr Lille: http://en.wikipedia.org/wiki/Lille http://wikitravel.org/en/Lille Do not hesitate to contact us for more information.

Quantum computers and Pharo
by Dimitris Chloupis Dec. 10, 2015

Dec. 10, 2015

Still far fetched reality for the average pharo coder but Quantum computers are a reality non the less for the supercomputer world. http://9to5google.com/2015/12/08/google-says-it-has-now-proven-that-d-waves… With a claim that is 100.000.000 time faster than the average supercomputer, its hard to compute the potential of Pharo in such a computer. Quite a quantum leap for imagination :) http://arstechnica.com/science/2015/09/d-wave-unveils-new-quantum-computing… http://www.dwavesys.com/blog/2015/08/announcing-d-wave-2x-quantum-computer http://www.dwavesys.com/d-wave-two-system http://www.gizmag.com/silicon-quantum-computer/39711/

When a metaclass is initialised by the system ?
by Dimitris Chloupis Dec. 9, 2015

Dec. 9, 2015

I have read that a metaclass (class side of the class) is initialised when its loaded to the image by monticello, Are there any other cases when the initialize method of the the metaclass is being called ?

I have been coming across quite a bunch of online coding tools lately. e.g. http://www.codeskulptor.org/#demos-starwars.py Would be nice to have something like that in our community. Phil
