That means, you cannot materialize with this version a stream which was serialized with an older version. What you have to do is: 1) materialize your graph. 2) update Fuel. 3) serialize again. > This version does not add any new concrete functionality but has two main > achievements: a performance improvement and a design clean up. > > Many changes included in this release are part of a design clean up.

Re: [Pharo-project] Squeak/Pharo on touchscreen: requesting opinions

by StÃ©phane Ducasse

HI dimitry I'm slowly working on a clean of the way event are managed in Pharo (double dispatch instead of large case statements, use of objects instead of array). The idea is to be able to support extension like multitouch support, genie use. So if you are interested we could pair-clean but this is far from your current work. I'm eager to play with Pharo on an android device.

One can pass Aliens through the FFI. So to use callbacks with the FFI one creates Alien callbacks and passes them as arguments through FFI calls. Simple.

[Pharo-project] [ANN] Fuel release version 1.6

by Martin Dias

Hello! I want to announce the new release version number 1.6 of Fuel, a binary serialization framework for Pharo that provides extremely fast deserialization. More information on our home page<http://rmod.lille.inria.fr/web/pier/software/Fuel>. Again, I thank ESUG for sponsoring me through the SummerTalk<http://www.esug.org/wiki/pier/Promotion/SummerTalk/SummerTalk2011>program. You can download this version in Pharo 1.2.1 with: Gofer new squeaksource: 'Fuel'; package: 'ConfigurationOfFuel'; load. ((Smalltalk at: #ConfigurationOfFuel) project version: '1.6') load. This version does not add any new concrete functionality but has two main achievements: a performance improvement and a design clean up. Many changes included in this release are part of a design clean up. They are a necessary step forward to new functionalities that are coming soon. They make code more understandable. They enable simpler extension. Happily they also helped to improve serialization performance by reducing unnecessary interactions. And it is specially important a bottleneck in graph analysis stage we have successfully attacked, obtaining great results. Details: - Removed explicit references to cluster classes scattered around the system. For example, in previous versions Float>>fuelCluster has an explicit reference to FLFloatCluster. This version replaces this by a double dispatch interaction. - Clusters: Better reification. Removed annoying IDs. Removed Singleton instance creation mechanism, now mappers manage uniqueness in a better way. - Mappers: They were simplified. New mapping machanism inspired on Chain of Responsibility pattern. The global objects detection has been optimized considerably. - Analyzer: Part of its behavior and state has been moved to a new abstraction called 'clusterization'. Best regards, MartÃn Dias
