New Pharo Collections

by AlexanderBrenchev

Greetings to everyone. My name is Alexander Brenchev, and I want to tell you about my recent project, which will be my pre-bachelor work. The goal of my project is to make a new collections for Pharo Smalltalk. We have a great plans about list of important collections, but we also need your opinion about them. So, feel free to make your suggestions about collections which you want to be implemented. The project page is available here <http://smalltalkhub.com/#!/~OBrenchev/NewPharoCollections> Now I want to tell something about what I've done so far: 1) A brief documentation about current collections hierarchy <http://pillarhub.pharocloud.com/hub/brenchev/6a1y5kdcbxhpeh7nl52v7s5i3> 2) A workflow of developing new collections for Pharo <http://pillarhub.pharocloud.com/hub/brenchev/6jxn656dns6gzhrno97bw5ktj> 3) Little tutorial which describes how to bring new collections for Pharo <http://pillarhub.pharocloud.com/hub/brenchev/2v6tkm9e2s5xl8xikjg64278j> As you can see, PillarHub will be a platform for my blog, where I will tell you about my faults and victories. I have no great results for now, but I've tested the main idea of collections development workflow, and now i am well-armed to make something that really matters. Stay tuned to PillarHub, ESUG and smalltalkhub to see the latest progress of the project. Thanks everyone. -- View this message in context: http://forum.world.st/New-Pharo-Collections-tp4794762.html Sent from the ESUG mailing list archive at Nabble.com.

by Johan Fabry

Sorry, but no :-( I am always confused when people say ‘category’ because the word has so many overloaded meanings. The same happens in the blog post, it is not clear to me what category means here, and what does it have to do with the collection object? > On Dec 7, 2014, at 11:16, Tudor Girba <tudor(a)tudorgirba.com> wrote: > > Hi, > > Yes, we will still evolve the UI.

Hi, Yes, we will still evolve the UI. At the very least you will get the shortkeys directly on the actions. The answer to your question is in the blog post: GTSpotter offers an extra action: diving in a category. Pressing Cmd+Shift+ArrowRight dives in the collection object containing only the items from that category. Thus, we can continue refining the search inside the category. So, you will open the collection of that sub-category and you will see more items at once (not just 5). Is it clearer now?

Hola, Andrei demoed it to me on friday and it is *extremely* cool. I can’t wait to start using it for my next development session. I have one request though (as I already mentioned to Andrei). Since you are using a significant part of the screen, it would not be costly to (e.g. at the bottom) put a small legend of the non-obvious keystroke combinations. It would greatly increase discoverability of the features of the tool. Considering the blog post, the legend would be ( I don’t understand the difference between the last 2): Cmd+Shift+ArrowUp/ArrowDown = Next/Prev category, Cmd+RightArrow = Dive into, Cmd+Shift+RightArrow = ??? > On Dec 7, 2014, at 10:14, Tudor Girba <tudor(a)tudorgirba.com> wrote: > > Hi, > > Alex Syrel, Andrei Chis and I are happy to announce a new addition to the Glamorous Toolkit: > GTSpotter, a novel interface for spotting objects. > > GTSpotter has two goals: > - Provide a uniform yet moldable interface that can work on any object, and > - Handle searching through arbitrary levels of object nesting. > > We think this will have a significant impact on the development workflow in Pharo. > > Here is a couple of screenshots: > <gtspotter-packages-classes.png> <gtspotter-dive-class-method-sender.png> <gtspotter-playground.png> > > > A trailer is available here: > https://www.youtube.com/watch?v=PhSmjR3NOlU > > A detailed description is available here: > http://www.humane-assessment.com/blog/introducing-gtspotter > > It works already in Pharo 3.0 and can be played with by following the instructions from: > http://gt.moosetechnology.org > > Please let us know what you think. > > Enjoy, > The Glamorous Team ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

[ann] gtspotter: a moldable interface for spotting objects

by Tudor Girba

Hi, Alex Syrel, Andrei Chis and I are happy to announce a new addition to the Glamorous Toolkit: GTSpotter, a novel interface for spotting objects. GTSpotter has two goals: - Provide a uniform yet moldable interface that can work on any object, and - Handle searching through arbitrary levels of object nesting. We think this will have a significant impact on the development workflow in Pharo. Here is a couple of screenshots: [image: Inline image 2] [image: Inline image 1] [image: Inline image 3] A trailer is available here: https://www.youtube.com/watch?v=PhSmjR3NOlU A detailed description is available here: http://www.humane-assessment.com/blog/introducing-gtspotter It works already in Pharo 3.0 and can be played with by following the instructions from: http://gt.moosetechnology.org Please let us know what you think. Enjoy, The Glamorous Team

Dear Smalltalking Friends I would like to this mail with you. ESUG is happy to have supported this cool action. Stef > Dear ESUG Board, > > As you may know, last week was held the Summer School on OOP with Smalltalk, in Cochabamba, Bolivia. We would like to share with you some of great moments we had, and what we plan for the future. > > The week was structured as follow: > - Each morning was Smalltalk classes. On Monday and Tuesday we have theoretical questions and some exercises. Wednesday, Thursday, and Friday we had small project developments. > - In the afternoon, we had tutorials (Seaside, Gemstone, Fuel, Profiling, Empirical studies) in addition to some academic meetings (with other professors, to foster research in Bolivia). > > Students were really enthusiastic. A core of 20 students attended at all the classes. Few local teachers were also part of the students. > > On Friday, we had a 1 hour session that where students presented and demonstrated their small projects. It went pretty well! Quality of the presentation were excellent, comparable with what we experience in Chile, Argentina or in Europe. > Most of the projects were made around Roassal and Moose. ObjectProfile sponsored a book "Deep into pharo", in addition to some certificated for distinguished projects. > > For the future, we will take the following actions: > - Nelson will work on a Ruby importer for Moose. He is already in contact with people from Bern > - Two students will continue to work on a code execution profiler, we hope to produce an academic artifact from this effort > - Next year we have planed to conduct another summer school > - Some students have also expressed their interesting in doing a Master in Chile > > Here are some links: > http://sla.memi.umss.edu.bo > https://sites.google.com/site/escuelaveranosmalltalk22014/ > https://www.icloud.com/photostream/#AK5nhQSTKlnaq;53972395-E8D5-48EF-A00E-5… > > > Kind regards, > Alexandre > > -- > _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: > Alexandre Bergel http://www.bergel.eu > ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. > > >

[Job] Search for job opportunities from Jan2015

by Jean Baptiste Arnaud

Hello, I am Arnaud Jean-Baptiste. I am working in Pharo community since five year. The Rmod adventure arrived to its term at the end of the month. I looking for jobs opportunities. I am interested to stay around the Smalltalk community, especially if it is in low level stuff :-) but I am open mind. I am available from January 2015. I am now in France, but moving even far away is not a problem. Here is a link to my linkedin page: https://www.linkedin.com/pub/jean-baptiste-arnaud/72/889/515 Here is a condense resume: My Experience: Since 5 years, I am in the Rmod team working on Pharo language: First I conducted a PhD focused on how to integrate new language features (I reified references), to enforce security policy. During my PhD, I acquired a deep knowledge of the Pharo virtual machine, language design and understanding complexe legacy software (when I began a PhD there are no correct documentation to rebuild the VM in a clean way). My PhD can be found on my website: http://jeanbaptiste-arnaud.eu/phd/ During my Post-doc, I parsed python language using moose for extract security information rely to static analysis. During my two last year I actively contribute to the Pharo/Squeak Virtual Machine. In addition, I worked 6 months with Synectique (software quality company focus on legacy langage), my job was to parse and extract data from Cobol language to provide visualisation (more detail can be found: http://jeanbaptiste-arnaud.eu/cobol/) On other side, I cultivate interrest on low level features, I am the maintainer the NBOpenGL implementation and provide some tutorial and simple tool (texture importer, mpeg renderer, etc.). I am the actual developer and maintainer of the RaspberryPi PharoVM project: (http://files.pharo.org/vm/pharoS/raspbian/) I began to introduce FFI for ARM. I revive the android project based now on the unix source (source are now merged in Pharo master, (after the refactor the code will be merge with the squeak repo too)), and soon a release will arrive I am testing it now. Other projects or more fun projects: - Opal compiler, at beginning of my PhD I was developer on the Opal project: - Storm, a binding of a 2D physical engine (focus for game), I am contributor on the project of Esteban Lorenzano, - Gameboy, I began to do from scratch a gameboy emulator (try to be closest possible of the hardware), on Pharo based on the documentation found on: http://gbdev.gg8.se/wiki/articles/Main_Page, It is fun and I made great advance (graphic/engine/memory/processor ok, need to finish material binding interrupt and debug), but sadly I do not have time anymore. - Phratch, I also contribute to Phratch project Obviously, I am a Pharo contributor. Here some peoples that can recommend me: Pharo community contacts: - Stephane Ducasse, my actual boss lead the Pharo community: stephane.ducasse(a)inria.fr - Igor Stasenko, a Senior developer involve in Pharo community: siguctua(a)gmail.com - Esteban Lorenzano, a Senior developer involve in Pharo community: estebanlm(a)gmail.com Synectique contacts: - Nicolas Anquetil, researche and lead member of Synectique: Nicolas.Anquetil(a)inria.fr - Usman Bhatti, developer and project lead. usman.bhatti(a)gmail.com Here is my pdf a academic version of my resume: Best Regards Dr Arnaud jbaptiste.arnaud(a)gmail.com
