Reward for a "MagSafe to MagSafe 2 Converter"

by Sean P. DeNigris

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...

Camp Smalltalk

by Johan Brichau

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

PhD topics with RMOD

by Stéphane Ducasse

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.
