Squeak leadership meeting june 4 208
by tim Rowledge 05 Jun '08

05 Jun '08

Deliberately concise message this time - 3.10.x - will continue to be pushed by Randal as needed. 4.x will be driven by Craig as a license-clean, modular system. Licensing issues will be addressed to Craig as he continues to be the conduit to SFLC etc. We discussed, without reaching a conclusion, the issue of naming VMs and images. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Loyalty oaths.Secret searches.No-fly lists.Detention without legal recourse.Remind me - who won the cold war?

My view on Traits
by Igor Stasenko 04 Jun '08

04 Jun '08

Traits is major feature added since 3.9. And i think it should STAY. I don't see any good reason, why next releases should not support traits. Instead of thinking about, how to get rid of them, i think we should think about, what in traits implementation prevents people from loading code based on 3.8 without much stress, and based on this knowledge, refactor traits to be more compatible with other non-traitified code. But they should stay! -- Best regards, Igor Stasenko AKA sig.

The version 3.10 does not work on Linux.
by Diogenes Moreira 03 Jun '08

03 Jun '08

--------- Sorry by my google english-------------- The version 3.10 does not work on Linux. Folks. This afternoon download the 2 (3.10 and 3.10-1 Versions) official versions from the official FTP but these images doesn't run on Linux (my desktop is a kubuntu.). By someone reason, world doesn't is displayed . As I did not leave any log or anything similar I cant give you more details. I Understand, that most of you have mac and this is the test platform by excellence, but take into consideration that there are an enormous number of people who do not have the resources and the only alternative we have left (without falling into piracy, off course) , is linux. Furthermore, since the personal field, I recommend give more support to open sources platforms, of which we are a part. Giving more support as Mac and Windows platforms, is a sort of betrayal. I really cant judge (in addition to recently that I am in this community) what are the motivations that each has to carry squeak ahead, but I can say is that Squeak must be faithful to their roots and ideals and become an option allowing the development of quality in the purest form possible POO. Since no environments objects "Clean" are not part of the technology of "Main Stream" I think that everyone is responsible is reached REALES consistent with what is preaches in Squeak and not just to be supportive "dummy" to open source platforms and development is made on platforms and shut out of reach for most of us who we live south of Rio Grande. As a last resort I had to download and use the latest images of Demian Causses (which actually runs on all platforms supported by squeak). I do not take bad, but I think that instead of discussing fribolidades as renaming a squeak or if it is only a platform for research or not, we should seek to improve this towards a modular platform and have a solid. For this goal we need the board to take reins in the matter and will lead to the release team with a clear objective, and not be carried by winds from a list of mail or those who IRC # pass. I believe that the inclusion of Dan Ingalls on the board would take such an effect, but it seems that we will have to wait for another leader emerges who drives the fate of squeak. I hope you do not take my comments wrong, try to be as frank as possible. I ask forgiveness if something political mistake committed, but this is what I think. I write the mail in two languages I know to be more clear with everyone. Honestly. La version 3.10 no funciona en linux. Amigos: Esta tarde baje las 2 versiones oficiales, que estan el ftp de squeak y ninguna de estas funciona en linux (mi desktop es un kubuntu.). Por algún motivo particular nunca se abre el mundo. Como no me deja ningun log no puedo darles mas detalles. Yo en tiendo que la mayoría de ustedes tenga mac, y esa sea la plataforma de prueba por excelencia, pero tengan en cuenta que hay una enorme cantidad de gente que no disponemos de los recursos y la única alternativa que nos queda (sin caer en la piratería porsupuesto), es linux. Por otro lado, y ya desde el ambito personal, les recomiendo que apoyen mas a las plataformas open sources, de la cuales somos parte. Dar mas soporte a plataformas como mac y windows, es algún tipo de traición. Realmente no puedo juzgar. (ademas que hace poco tiempo que estoy en esta comunidad) cuales son las motivaciones que cada uno tiene para formar parte de Squeak, pero lo que si puedo decir, es que Squeak debe ser fiel a sus raices e ideales, y convertirse en una opcion de calidad que permita desarrollar en la forma mas pura posible la POO. Dado que los entornos de objetos "Limpios" no son parte de las tecnología del "Main Stream" creo que es reponsabilidad de todos, que los se llegue a realeses coherentes con lo que se predica en Squeak y no solo que se de soporte "dummy" a las plataformas open source, y que el desarrollo se haga sobre plataformas cerradas y fuera del alcance de la mayoria de nosotros que vivimos al sur de rio grande. Como ultimo recurso tuve que bajar y usar las ultimas imagenes de Demian Causso (que realmente funcionan en todos las plataforma soportadas por squeak). No me tomen a mal, pero creo que en lugar de discutir fribolidades como cambiar el nombre a squeak o si es solo una plataforma de investigacion o no, deberíamos buscar mejorar esta en pos de una tener una plataforma modular y solida. Para este objetivo necesitamos que el board tome acciones al respeto y conduzca al release team con un objetivo claro, y no sea llevado por los vientos de una lista de mail o los que pase en #IRC. Yo crei que la inclusion de Dan Ingalls en el board iba a tener en ese efecto, pero parece que vamos a tener que esperar que surja otro lider que conduzca el destino de squeak. Espero que no tomen a mal mis comentarios, trate de ser lo mas franco posible. Les pido perdon si cometi algo error politico, pero esto es lo que pienso. Sinceramente.

Poor Squeak performance on Vista
by Maurice Rabb 03 Jun '08

03 Jun '08

Hello, One of our students is having trouble with very poor Squeak performance on Vista. I was hoping that someone with Windows experience could help diagnose his problem. Philip writes: "Is anyone else having problems with Squeak being incredibly slow to respond? It was fine the past couple of days, but it just started happening to me tonight. I have reset Squeak, and my system. I have also downloaded new images. Nothing seems to help. Also, my HD light isn't on, nor is my comp processor utilization being eaten up. Any ideas?" Also: "I have closed most of the [Squeak] windows and that doesn't help." "I tried the roundedWindowCorners preference and the higherPerformance preference, and I changed the VM system configuration to disable "Reduce CPU usage". None of this helps. I am not doing any memory or internet intensive things. There is sometimes up to a 10 second delay between me clicking, and the World menu showing up. I am using VM Version 3.10.6 and Squeak system version 3.9.1. I have Windows Vista (unfortunately). I checked the Process Browser and idle process definitely is the max value averaging around 90% and the rest of the percentage going to the GUI and the auto-update. Any other thoughts? Philip" Thank you, Maurice

Two methods sharing source code?
by Martin Beck 03 Jun '08

03 Jun '08

Hi there, for some reasons, I want to have two methods sharing the same source code base. So if I change one method within the browser, the other would change, too. Is this possible in Squeak? And, would the usual tools work with that? Regards, Martin

About SQLite and squeak, seaside
by Torsten Bergmann 03 Jun '08

03 Jun '08

Hi Witali, anything you need is - FFI (take care of the FFI fix in http://bugs.squeak.org/view.php?id=6980 if you use a new 3.10 image) - http://www.squeaksource.com/DeveloperWorkspace/SQLite3-tbn.1.mcz (which is just the code from http://map.squeak.org/package/b396aec0-e9cd-4e70-8746-eb38284f75af packaged as Monticello versioned file) - the native library for your platform from http://www.sqlite.org/download.html The library name is defined in SqliteLibrary(class)>>moduleName, so you need the sqlite3.dll for Windows for example (sqlitedll-3_5_9.zip on the download page). Place it in the same directory as the Squeak virtual machine. Have fun Torsten -- GMX startet ShortView.de. Hier findest Du Leute mit Deinen Interessen!

[Q] About updating Squeak and some troubles
by Edgar J. De Cleene 03 Jun '08

03 Jun '08

Folks: I trying to do a .cs only of 3.10 Ralph always wish we could hit load updates button from 3.9 and load the updates. Except in the few cases of loading very complex changes for Monticello this works When hit load updates button from 3.9 fresh image fail, I start to dig why Utilities class>>extractThisVersion:list gives us today #('Squeak2.5' 'Squeak2.6alpha' 'Squeak2.6' 'Squeak2.7alpha' 'Squeak2.7' 'Squeak2.8alpha' 'Squeak2.8' 'Squeak2.9alpha' 'Squeak3.0' 'Squeak3.1alpha' 'Squeak3.1beta' 'Squeak3.2alpha' 'Squeak3.2gamma' 'Squeak 3.2' 'Squeak3.2' 'Squeak3.2.1' 'Squeak3.3alpha' 'Squeak3.4alpha' 'Squeak3.4beta' 'Squeak3.4gamma' 'Squeak3.4' 'Squeak3.5alpha' 'Squeak3.5beta' 'Squeak3.5gamma' 'Squeak3.6alpha' 'Squeak3.6beta' 'Squeak3.6gamma' 'Squeak3.6' 'Squeak3.7alpha' 'Squeak3.7beta' 'Squeak3.7gamma' 'Squeak3.7' 'Squeak3.8alpha' 'Squeak3.8beta' 'Squeak3.8gamma' 'Squeak3.8' 'Squeak3.8.1a' 'Squeak3.8.1' 'Squeak3.8.2a' 'Squeak3.9alphaold' 'Squeak3.9alpha' 'Squeak3.9gamma' 'Squeak3.9.1' 'Squeak3.9.2' 'Squeak3.10alpha' 'Squeak3.10beta' 'Squeak3.10.1-basic' 'Squeak3.10.1') And in updates.list file I see #Squeak3.9.1 7068advance391a.cs 7069FixingDirtyMultilangual.cs 7070UnloadingOB.cs 7071FreeFixes.cs 7072SemaphoreFixes.cs 7073DelayFixes.cs 7074FixOrderOfRegisteringStartUpList.cs 7075FixingRefToImageBrowser.cs #Squeak3.9.2 7068AdvanceToThreeDotTenAlpha.cs #Squeak3.10alpha 7069ConvertTo3dot10.cs Seems odd to me having 3.8, 3.8.1. 3.8.2 and 3.9, 3.9.1, 3.9.2 and 3.10 , 3.10.1 etc Seems odd to me having same numbers for different things. When one release ends, we should learn from mistakes and move to the. You don't try to load Vista programs in your Windows 98 , don't you? Edgar

Questionable constraint in ProportionalSplitterMorph
by Trygve Reenskaug 03 Jun '08

03 Jun '08

Squeak3.10.gamma.7159, WinXP/SP2 I have a window with four panes: top left: LayoutFrame fractions: (0@0 corner: 0.2(a)0.5)). top right pane: LayoutFrame fractions: (0.2@0 corner: 1(a)0.5). bottom left pane: LayoutFrame fractions: (0(a)0.5 corner: 0.19@1). bottom right pane: LayoutFrame fractions: (0.19(a)0.5 corner: 1@1). self addPaneSplitters does its impressive magic; a horizontal pane splitter right across the window at y=0.5 two vertical pane splitters one between top left and top right and another between bottom left and bottom right. (The latter two has 'splitsTopAndBottom'=false) The curious thing is that the two vertical pane splitters are linked; any one of them cannot be moved past the other one. The constraint is in these methods /*ProportionalSplitterMorph>>*/ *normalizedX: x* ^ (x max: self leftBoundary) min: self rightBoundary *rightBoundary* ^ (self splitterRight ifNil: [self containingWindow panelRect right] ifNotNil: [self splitterRight left]) - 50 *splitterRight* | splitters | splitters _ ((self siblingSplitters select: [:each | each x > self x]) asSortedCollection: [:a :b | a x < b x]). ^ splitters ifEmpty: nil ifNotEmpty: [splitters first] *siblingSplitters* ^ self owner submorphsSatisfying: [:each | (each isKindOf: self class) and: [self splitsTopAndBottom = each splitsTopAndBottom] and: [each ~= self]] Does anybody know the motivation for this curious behavior? The easiest workaround would be to hack *siblingSplitters *to return an empty collection. Perhaps it would be better with a new preference? (Subclassing /*ProportionalSplitterMorph*/ does not seem practicable). I'll be grateful for enlightenment about this curious behavior. --Trygve ** -- Trygve Reenskaug mailto: trygver(a)ifi.uio.no Morgedalsvn. 5A http://heim.ifi.uio.no/~trygver N-0378 Oslo Tel: (+47) 22 49 57 27 Norway
