[Pharo-project] [ANN] Fuel release version 1.6
by Martin Dias Aug. 19, 2011

Aug. 19, 2011

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

If I remember correctly she also created the skin for pharocasts and Marea: http://www.pharocasts.com/2010/01/learn-smalltalk-with-profstef.html http://rmod.lille.inria.fr/web/pier/software/Marea/GhostProxies Really nice and clean design! Mmmhhh ... Pharo still needs: - a better icon set (than the toyish squeak icons) to look more professional - a nice splash screen - better design templates for articles, books, refcards, powered by, ... Currently we only have http://www.pharo-project.org/pharo-download/media-files I would like to see more templates (SVG, ...) one can use to mix it for own designs, webpages, ... - ... Maybe she can help us here? Thx T. -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

[Pharo-project] Squeak/Pharo on touchscreen: requesting opinions
by Dimitry Golubovsky Aug. 19, 2011

Aug. 19, 2011

Hi, As I am progressing through the Stack Cog port for Android (basically I can load a recent PharoCore or Squeak image althoug some stability issues still exist), I would like to collect opinions from prospective users, which is a better way to interact with Squeak (meaning Pharo and others as well) on a touch screen. 9" tabet screen is not much smaller than say EEE PC netbook's, so at 800x480 px resolution menus and other Squeak GUI elements are well readable, and can be easily pointed at with a stylus. So Squeak environment itself can be as well used even on my rather cheap device. Squeak requires a lot of mousing to interact. On an Android device, there is a touch screen, and possibly several hardware buttons. In the current implementation taps on the screen are treated as "red" clicks, and pressing one of hardware buttons prior to tapping the screen change click color just for one click: see this picture: http://wiki.squeakvm-tablet.googlecode.com/hg/pics/pdn-land.jpg That is, in order to get a context menu in Squeak, one has to press the "Yellow" hardware button (in PharoCore it is the "Blue" button), and then tap the screen; the menu appears. See the whole explanation at http://code.google.com/p/squeakvm-tablet/wiki/TestDrive This is how the classic (based on Andreas' code) Squeak VM port works now, and I have the same working in Stack Cog. Advantages of this method: it is close to the way traditional mobile applications interact. In a Squeak application, a Morph has to set proper handling of red button clicks in order to enable interaction with user. Morph drag can be done with one hand (however by a reason I could not explain, morphs disappear from the screen while being dragged, and reappear in new location only when tap is released). Disadvantages: current mouse position is unknown/invisible to the user, mouse over is impossible (hence no balloon help). Also due to high touchscreen sensitivity, holding a finger/stylus on the screen may generate many events within short period of time, since even one pixel change in touch position causes an event to be generated, and some involuntary finger movements always take place. Such frequently reported events may "choke" the interpreter, given the CPU is slow, and Android OS quickly kills it due to unresponsiveness. While I am trying to address these issues in various ways, there seems to be another way to interact via touchscreen. This method has not been implemented yet, and I would like to hear from the community whether it could be good to have. A mouse pointer is displayed as part of the activity interface (maybe even done entirely in Java, so mouse movement itself will not put any load on the interpreter). Finger movements on the screen move the pointer, but new position is reported (with button mask 0) only when the screen tap is released. So mouse over becomes possible: just leave the pointer where needed. The hardware buttons are used as before (one becomes Red, another Blue, and a chord would be Yellow), but clicks only are reported when those buttons are pressed or released*. To drag a Morph, one would have to hold one of the hardware buttons, and slide their finger/stylus on the screen. So this hypothetical mode is more like laptops' trackpads work. One obvious advantage of this method is less load on the interpreter in terms of the frequency of events, and hence greater stability, although less convenience. Again, to run an end-user application, the former mouse tracking method may be enabled. I am asking your opinion here (as much of opinion can be had about something only imaginary) - is the latter method worth implementing: would one like to use it if available? Thanks. ------------------------- * or long taps may be recognized as red clicks -- Dimitry Golubovsky Anywhere on the Web

[Pharo-project] Alien bug fix
by Eliot Miranda Aug. 19, 2011

Aug. 19, 2011

Hi All, I've just published Alien-eem.14 to http://www.squeaksource.com/Alien. This fix needs to be integrated into each dialect's version of Alien. The bug causes VM crashes due to trying to free stale pointers from previous runs. Alien-eem.14 Author: eem Time: 18 August 2011, 10:34:20.024 am UUID: 39bedad1-6159-4ba4-be35-277df2a25977 Ancestors: Alien-eem.13 Fix startUp: discarding of stale values from Alien's GCMallocedAliens class var. -- best, Eliot
