[Pharo-project] keeping up with lively-kernel (morphic)
by Lawson English Feb. 2, 2012

Feb. 2, 2012

It seems to me that the most active place where development of Morphic is taking place is in the context of Lively Kernel. Is anyone tracking what the LK people are doing and seeing how it can be backported, or used to create a new version, or integrated with the current version of Morphic or Cuis, etc? Lawson

[Pharo-project] Boolean Logic
by Robert Sirois Feb. 2, 2012

Feb. 2, 2012

Ok, this may be from a simple lack of understanding, but I just have to know ;) Why can I call #or: (Boolean and friends) with a block, but #xor: only takes a Boolean? I would think the paradigm would remain the same and be able to compose operators like #or:, etc.? What am I missing? Thanks! RS

[Pharo-project] Fwd: [vwnc] Smalltalk for small projects only?
by Janko MivÅ¡ek Feb. 2, 2012

Feb. 2, 2012

-------- Prvotno sporoÄilo -------- Datum: Tue, 31 Jan 2012 07:54:58 -0600 Od: Peter Hunsberger <peter.hunsberger(a)gmail.com> With all due respect to the experience of everyone here, people really need to give up on this naive belief that Smalltalk development is any more efficient than development in any other language. The simple fact is that within the Smalltalk community a large portion of the developers have been using the tools for a long time and are very good at using them. Throw them at another environment and they are not as efficient. However, if you take new developers and throw them at a Smalltalk project it takes longer to get them up to speed than throwing them at a Java project simply because of the fact that Smalltalk is not as ubiquitous. I switched to Java back when IBM dropped Smalltalk, so I've seen both sides of this issue for a long time, so let me related some anecdotal experience: I'm currently working on a Smalltalk project that has about about 50 man years of effort in it over 10 years. Prior to this I worked on a Java and XSLt project that had about the same effort over the same period. Both have web based GUI's with a fair amount of JavaScript and the usual HTML crud and use a relational DB back end (SQL server and Oracle respectively). The Smalltalk project has had a mix of very experienced Smalltalk developers and inexperienced ones. The Java project was mainly junior and intermediate experience devs. I'd say the overall architecture and design was about equivalent; very different, but equally well done and comprehensive. The projects are very similar in concept and execution. The Java project had about twice as many function points (some pretty major) implemented and four times as many use cases supported at the point I switched to the Smalltalk project. For the most part this has little to do with the language itself. Rather, it is mainly, the supporting infrastructure that one is able to draw on in Java projects and this includes Eclipse, Git, etc. Open Source projects also played a big part of this, in the Java world one can pull in large chunks of functionality at very low cost (eg. XSLt 2.0 processors and pipelines, Spring, Hadoop, you name it) that are just not quite matched in the Smalltalk world. You can often get close, but it seems that there is always something missing, if only because the teams supporting the Smalltalk projects are often much smaller and just can't quite keep up with the every changing specs and requirements. Bottom line, don't kid yourself that there is any inherent advantage in using Smalltalk development over any other language. It is faster for experienced devs in small projects, but if you've got to pull a team together from scratch for some medium to large complexity enterprise scale project it is probably not going to fair as well. Now onto the main question posed here.... I have also worked on a successful 200 man year project (C and C++ in this case), which broke down to a little less than 100 people over a little more than 2 years. This was in the telecom world and involved many main frame billing interfaces and switching equipment interfaces, all very mission critical. In this case about 60% of the team was heads down developers. The rest of it was dedicated testers, tech writers, business analysts, project managers and managers. Here again the supporting infrastructure played an important role. Business analysts could write up use cases that got stored in a repository (a proprietary system) that could be used to generate test case stubs and documentation stubs. The development team tracked progress and bug reports in the same repository and source code version control was tied to the repository. End user documentation was stored in the repository and version controlled. It was simple to know what was going on anywhere in the project and to know where the problems were and what code did what and to see the entire life cycle of any portion of the code base from customer requirement to final deliverable. I know of no support infrastructure that even comes close in the Smalltalk world and would consider it madness to even consider taking on such a project using Smalltalk.

-------- Prvotno sporoÄilo -------- Datum: Wed, 1 Feb 2012 11:54:22 -0500 Od: Paul Baumann <paul.baumann(a)theice.com> Peter's point that "that there is [not] any inherent advantage in using Smalltalk development over any other language" is true by the criteria that he defined to judged it. It is funny to see "Smalltalk efficiency" is being framed by a standard of high resource requirements, and that Java having twice as many function points and four times as many cases for equivalent architecture and design was somehow a less relevant measure. One might observe that having such a wide variety of similar tools for a language like Java can indicate a limitation of reuse and extension. Smalltalk syntax is less restrictive in how a framework can be reused and extended; that is a better criteria to judge efficiency of the language. "Smalltalk" is syntax and a basic class library; it is not defined by the availability of a vendor features. IBM failures are more relevant than a Smalltalk failure. Large IBM projects of that era failed from Analysis Paralysis. A common goal was compliance with the latest buzz that IBM sold. There were a multitude of management styles in vogue at that time and all could be characterized as top-down management. The "60% heads down developers" were given static designs that had a high and continuous cycle of costs as theory met reality. Large amounts of dumb and redundant code would be generated early. Code inertia and resistance to change would preclude opportunity that is discovered later (like the ability to eliminate thousands of classes with a single reusable type). The result is as predictable as any top-down management style. All design problems were prevented from being fixed until they caused serious and recognizable problems. The management styles of the time promised theoretical efficiencies of scale that had been determined from earlier failures with less malleable languages than Smalltalk. Effectiveness of these feudalistic management styles had yet to be recognized as Dark Ages in the context of software development. Smalltalk does well when individual developers are given opportunity and responsibility, and to the extent that implementation is not restricted. Success with Smalltalk is about rewarding independent action that furthers an objective goal. Management of a Smalltalk project is about providing healthy incentives while minimizing barriers to change. Top-down management (sold by IBM) was more to blame than "Smalltalk". Smalltalk is successfully used for large mission-critical projects that affect global markets. It doesn't take even a dozen Smalltalk developers to do that. Smalltalk can be more efficient than other languages when a compatible management style is used. Smalltalk struggled through the Dark Ages of project management while more popular languages were developed outside of those conditions. Smalltalk is a victim of timing, management, and vision. The more popular languages provide opportunity of market more so than opportunity of syntax. Languages have evolved to be increasingly more malleable like Smalltalk; that is recognition of an advantage that Smalltalk has always had rather than proof that Smalltalk never was more efficient. Some people value opportunity of syntax that Smalltalk offers and have the vision to leverage that to a competitive advantage. Other people recognize that the availability of resources and frameworks can also be leveraged as an advantage over Smalltalk. It is possible to find success or failure either way.

[Pharo-project] Clickable Source Code
by Camillo Bruni Feb. 2, 2012

Feb. 2, 2012

hi everyone, Today I hacked the ST80 Styler to support clickable source code links: - clicking on a Class name opens a Browser - clicking on a instVar shows al users of it ... The current limitation is the mouse-handling. Right now I run the actions on normal clicks, not really nice. I wish to only run an action on cmd-click (like in eclipse). However left / middle / right clicks are already handled high up in the morphic tree to generate these mostly useless menues... So I wonder is there a way to only get register for ctrl-click / alt-click / cmd-click? best cami

[Pharo-project] GL on fbdev (was: Re: [squeak-dev] Building Cog with vm-display-fbdev)
by Michael J. Zeder Feb. 1, 2012

Feb. 1, 2012

thanks to the hint of Eliot, I did some code updates. fbdev module for Cog is now committed. One thing I'm playing around with, and I have questions about, is the following (Eliot suggested to post it here): > A project for supporting the openGL lib to render output to fbdev (like that: http://www.mesa3d.org/fbdev-dri.html) would need major efforts, right? As far as I understand linux graphics architecture, it should be possible to render directly to the framebuffer device (maybe by a memcopy from a "FBO": http://songho.ca/opengl/gl_fbo.html) > But my knowledge doesn't reach far enough to figure out, if, how, and where that could integrate with existing/emerging squeak/GL infrastructure... I don't know if that would be a project of major importance ;) but â as squeak's/pharo's future graphics architecture is currently under discussion â I think it should be considered, that there are many different backends... The reason I asked is, that I currently build me a tiny core linux system with a smalltalk user land. It does work and it is fun... So thanks for any feedback! I enjoy Smalltalk :) Cheers Michael Am 30.01.2012 um 18:54 schrieb Eliot Miranda: > Hi Michael, > > On Sun, Jan 29, 2012 at 1:12 PM, Michael J.

That support was implemented for vm-display-X11 and vm-display-null but not for vm-display-fbdev. You'll need to implement similar stubs that you'll find in the vm-display-null, since most of these primitives don't make sense/don't do anything in the context of fbdav (which takes control of the frame buffer and is hence always full-screen).
