IMPORTANT: ESUG social event on wednesday
by Johan Brichau Aug. 28, 2012

Aug. 28, 2012

To all ESUG participants: There is some confusion concerning the social event schedule due to the entire afternoon being marked as 'social event' on the ESUG programme. Here is the one and only truth: - The social event starts at 17h15 at the designated meeting point (see the map on the conference website http://www.esug.org/wiki/pier/Conferences/2012) - The awards prize ceremony will be at the social event dinner In addition: if you have changed your mind w.r.t. attending the social event (i.e. different from what your online registration says): TALK TO ME. There is a limited number op places at the social event _and_ about 30% of all participants have registered in the last 3 weeks, which means I have run out of spare seats. Hope you are enjoying esug!

Reward for a "MagSafe to MagSafe 2 Converter"
by Sean P. DeNigris Aug. 25, 2012

Aug. 25, 2012

If anyone coming to the conference has an extra $10 little Macbook-pro-retina-to-every-other-mbp-in-the-world power adapter (a.k.a. a "MagSafe to MagSafe 2 Converter" [1]), or will be passing an apple store and can pick one up, I would not only reimburse you, but reward you in powerful belgian beer :) I forgot my power cord, and just realized that my laptop is totally incompatible with everyone else's... Thanks, Sean [1] http://store.apple.com/us/product/MD504ZM/A/magsafe-to-magsafe-2-converter -- View this message in context: http://forum.world.st/Reward-for-a-MagSafe-to-MagSafe-2-Converter-tp4645261… Sent from the ESUG mailing list archive at Nabble.com.

Camp Smalltalk
by Johan Brichau Aug. 25, 2012

Aug. 25, 2012

To those coming to Camp Smalltalk this weekend: There is a flea market in the entire neighbourhood. This means there is also a vendor in front of our door, but I have put a sign on the door and the vendor made a passageway. Just ring the bell and I will come down to open the door. But in case you get lost: +32 476 78 64 45 Johan

GSoC - Package management with Fuel
by Martin Dias Aug. 24, 2012

Aug. 24, 2012

Hi This week has ended Google Summer of Code program 2012. I have to thank Marcus and Carlos Ferro, my mentors, as well as Mariano, Guille Polito, Camillo Bruni, and others, who collaborated in different ways during these three months. Also thank, of course, to Carla and Janko... and Google ;) The main purpose of this mail is to summarize the work done for my project, named "Package management with Fuel" [1][2]. Tools for managing code in Pharo export classes, traits, and methods as series of source definitions, which then import by evaluating them with the compiler. This is basically how FileOut/FileIn or Monticello works. This is slow on large pieces of code, so if you want to install a big package, you need a lot of time compiling it. Why should you compile it again, given that it was all compiled when you exported the package? The bytecodes will be the same again, you know... If you just could load the Classes and Compiled Methods instead of compiling it all again, you can save time. With this goal in mind, I started working in FuelPackageLoader[4] (now Tanker[3]), a prototype we wrote last year, which already exports and imports packages without using any compiler. But it has two important issues: it wasn't capable of export source code, and it wasn't able to tolerate class-shape changes in hierarchies (ie, a change on inst vars in a external superclass). So, we decided to start from scratch with a new prototype, code name Carbono. The idea was to reify how FileOut and FileIn are done, but storing binary information so that compilation can be avoided. In a nutshell, Carbono stores a package into two files: - A sources file, imitating the traditional FileOut chunk format. - A binary file, where uses Fuel[5] to serialize a series of code definitions. Each of them knows the position in the sources file where its source code counterpart is. For example, a class definition knows the position of its comment (in the case it exists), and a method definition knows the position of its source code. A basic example, to export a couple of classes: TAExport new binariesOn: aBinaryStream sourcesOn: aTextStream; behaviors: {ClassA. ClassB}; methods: {}; initializeClasses: true; run. which then you can import with: TAImport new binariesFrom: aBinaryStream sourcesFrom: aTextStream; run. Anyway, you can also choose to: - export only binaries or only sources - import only binaries (source code can be decompiled) - import only sources (via #fileIn) Mariano Martinez Peck worked a lot on it, fixing bugs, and especially optimizing it A LOT, so I hope you will enjoy his demonstration this Monday on ESUG Innovation Awards. Seems that he could export Seaside, Pier and Magritte, and import them in another image, with source code, and just in a few seconds ;) Also, some ultra confidential WikiLeaks revealed that he could export almost all Pharo packages, and import them in a kernel image, all with source codes but without using the compiler :) Note1: Tolerating class-shape changes in hierarchies is not yet done, but it should in some days. So far, the only strategy when a change is detected will be to recompile methods, but it may be more sophisticated in a not-so-far future. Note2: Although finally it was not strictly necessary, Guillermo Polito and me wrote tests for a new ClassBuilder. It is part of Slot, a kind of reification of objects layout made by Toon Verwaest and Camillo Bruni. It is too long to explain it here, but the thing is that was not an easy job, and we hope it will be integrated in Pharo. This is a work in progress, but you can install and try it on latest Pharo 2.0, evaluating: Gofer it squeaksource3: 'PharoTaskForces'; package: 'Slot'; package: 'SlotTests'; load. (Smalltalk at: #SlotVirus) perform: #spread. Gofer it squeaksource3: 'PharoTaskForces'; package: 'SlotsClassBuilderIntegration'; load. Gofer new smalltalkhubUser: 'marianopeck' project: 'Tanker'; package: 'ConfigurationOfTanker'; load. (Smalltalk at: #ConfigurationOfTanker) loadBleedingEdge. Gofer new squeaksource: 'FuelExperiments'; package: 'Carbono'; package: 'CarbonoTests'; load.

PhD topics with RMOD
by Stéphane Ducasse Aug. 24, 2012

Aug. 24, 2012

Hi guys we have a position for a PhD. If you are interested we can talk at ESUG 2012 or by Skype. Stef Context: Dynamically-typed languages cannot take advantage of static type information. In this context we would like to study the benefit of the introduction of static types *annotations* on library design and general robustness. The benefits can be at the level of the robustness (bug identification), but also tools (IDE) and support for assembly generation/c in case of JIT. The PhD grant is financed in the context of the Safe Python project therefore the Ph.D. will have to work in contact do we with the project partners and help in the context of some deliverables. The following tasks have to be done: - RPython is not formally defined. One of the first task will be to define the formal semantic of RPython. One approach is to write a RPython interpreter based on an operational semantics and to compare the output with the RPython interpreter. We will certainly use PLT redex which is a domain-specific language to specify and debug operational semantics. - We may use the abstract syntax tree of PyLint and use the Frama-C infrastructure. We will also consider to build a Python parser based on petitParser. - Define of some default metrics may also be necessary for the SafePython project. Their definition should be trivial on ASTs. - Analysis of the benefits of static typing for RPython. One idea is to study the existing python libraries and analyze the "distance" to the RPython subset. - Exploring type checking in presence of inconsistent type annotations. - Since we are developing Pharo and that static type annotation are important to support C or assembly generation, we would like to apply the same technique to Pharo: - define a syntax to support type annotation (reuse the one developed by Pleaid team member) - perform some analysis of existing library.
